Sendo assim, a tese foi composta por introdução, objetivos, capítulos (I e II) e conclusão geral. A introdução apresentou os principais estudos sobre massa óssea e da técnica de avaliação deste tecido por meio da ultrassonografia de falange. No capítulo I e II encontram-se os artigos que foram redigidos segundo as normas específicas de cada periódico a que foram submetidos. Na conclusão geral foram apresentadas as principais conclusões dos dois artigos. As referências bibliográficas foram apresentadas no final de cada capítulo e da tese.

Objetivo: avaliar a quantidade e qualidade óssea, por meio de ultrassonografia das falanges, em escolares saudáveis, brancos e negros, em relação ao nível socioeconômico e composição corporal, e ainda comparar a quantidade óssea com referências européias. Materiais e Métodos: participaram do estudo 1.356 escolares saudáveis de diferentes níveis socioeconômicos, divididos em brancos e negros com idades de seis a onze anos, de ambos os gêneros. Por métodos antropométricos foram avaliados o peso e a estatura e calculados o percentual de gordura, massa gorda, massa magra e índice de massa corporal, que foi transformado em escore z para idade. Para definir os desvios de normalidade foram adotados como pontos de corte valores abaixo de -2 e acima de +2 dos valores do escore z. Para o procedimento de coleta das medidas individuais do parâmetro de quantidade óssea (AD-SoS = Amplitude Dependent of Speed Sound) e qualidade óssea (UBPI = Ultrasound Bone Profile Index) utilizou-se o ultra-som nas falanges com o aparelho DBM Sonic® BP, IGEA, de 3ª geração. Os valores médios de AD-SoS deste estudo foram comparados a cinco referências européias que apresentam valores normativos para crianças e adolescentes. Foi realizada a análise descritiva dos dados, e para a comparação da idade, dos gêneros e das cores da pele com as variáveis AD-SoS e UBPI, utilizou-se a análise de variância (ANOVA - two way) seguida pelo teste de comparações múltiplas de Tukey (p<0,05). Aplicaram-se ainda os testes Mann-Whitney, qui-quadrado, coeficiente de correlação e análise de regressão linear múltipla com significância de 5%. Para a comparação da AD-SoS dos escolares, de ambos os gêneros e cores de pele em relação às referências, recorreu-se ao teste t Student, que compara duas médias, sendo uma delas a referência. Resultados: Os escolares negros predominaram nos níveis socioeconômicos baixos. Os meninos negros apresentaram valores superiores no peso e estatura, enquanto as meninas negras na massa magra, em relação aos escolares brancos do mesmo gênero e idade. Observou-se variação crescente dos seis aos onze anos para ambos os gêneros e cor da pele nas médias de AD-SoS. Os brancos apresentaram valores superiores de AD-SoS e UBPI em relação aos negros. As variáveis antropométricas, gênero e nível socioeconômico explicaram apenas 17 e 11% da variabilidade de AD-SoS e UBPI, respectivamente. Comparando a AD-SoS deste estudo com as cinco referências européias, observou-se para ambos os gêneros e cores de pele valores inferiores ao estudo polonês e semelhante aos demais para as meninas, enquanto que os meninos apresentaram valores semelhantes aos estudos italianos e inferiores ao espanhol. Conclusão: Sendo assim, o presente estudo, apresentou massa óssea, avaliada por ultrassonografia das falanges, maior nos brancos que nos negros. A quantidade óssea dos escolares deste estudo aumentou dos seis aos onze anos de idade para ambos os gêneros e cores da pele. A quantidade óssea encontrada nas crianças brasileiras de ambos os gêneros e cores de pele foi inferior em relação aos poloneses, semelhante aos italianos; e em relação ao estudo espanhol, os gêneros não apresentaram uniformidades, sendo as meninas semelhantes e os meninos com valores inferiores. / Abstract: Thesis Structuring: The present study opted for the "Scandinavian Model" which is called the "Alternative Model" in the Post-Graduation Program in Child and Adolescent Health from the Medical Sciences College of University of Campinas (UNICAMP). Therefore, the thesis was compounded by introduction, objective, chapters (I and II) and general conclusion. The introduction presented the main studies on bone mass and the evaluation technique of this tissue by the use of phalanx ultrasound. The articles that were written according to the specific norms of each journal to which they were submitted to are found on chapters I and II. On the general conclusion the main conclusions of both articles were presented. The bibliographical references were presented at the end of each chapter and of the thesis. Further, the main information about the structuring of both chapters of the thesis was presented. Objective: to evaluate the bone quantity and quality, by phalanxes ultrasound, in healthy, black and white, schoolchildren, in relation to the socioeconomic level and body composition, and still, to compare the bone quantity to European references. Materials and Methods: 1,356 healthy schoolchildren from different socioeconomic level participated on this study, divided into black and white with ages from six to eleven years old, from both genders. The weight and height were evaluated by anthropometric methods as well as the percentage of fat, fat mass, lean mass and body mass index, which was transformed in score z for the age, were calculated. To define the normality deviations it was adopted, as cut points, values below -2 and above +2 from the values of the score z. For the procedure of collecting the individual data of the bone quantity parameter (AD-SoS = Amplitude Dependent of Speed Sound) and bone quality (UBPI = Ultrasound Bone Profile Index) it was used the ultrasound on the phalanxes with the 3rd generation DBM Sonic® BP, IGEA device. The average values of AD-SoS from this study were compared to five European references that presented normative values for children as well as for adolescents. The descriptive analysis of the data was realized, and for the age, genders and skin colors comparison with the variables AD-SoS and UBPI, the variance analysis was used (ANOVA - two way) followed by the test of multiple comparisons of Tukey (p<0,05). The Mann-Whitney, qui-squared, correlation coefficient and multiple linear regression analysis with 5% significance were also applied. For the comparison of AD-SoS of the schoolchildren, from both genders and skin colors in relation to the references, the t Student, that compares two averages, being one of them the reference, was chosen. Results: the black schoolchildren predominated on the low socio-economic levels. The black boys presented higher values for weight and height, while the black girls for lean mass, in relation to white schoolchildren from the same age and gender. It was observed a crescent variation from six to eleven years of age for both genders and color of skin in the averages of AD-SoS. The white schoolchildren presented higher values of AD-SoS and UBPI in relation to the black ones. The anthropometric variables, gender and socio-economic level explained only 17 and 11% of the variability of AD-SoS and UBPI, respectively. Comparing the AD-SoS from this study to the five European references, it was observed for both genders and colors of skin lower values than to the Polish study and similar to the other studies for the girls, while the boys presented similar values to the Italian studies and lower than the Spanish ones. This way, the present study, presented higher bone mass, evaluated by phalanxes ultrasound, in white schoolchildren than in black ones. The bone quantity of the schoolchildren from this study rose from the six to the eleven years of age for both genders and colors of skin. The bone quantity found in Brazilian children from both genders and colors of skin was lower in relation to the Polish, similar to the Italians; and in relation to the Spanish study, the genders didn't present uniformities, being the girls similar and the boys with lower values. / Doutorado / Saude da Criança e do Adolescente / Doutor em Saude da Criança e do Adolescente

Sendo assim, a tese foi composta por introdução geral, objetivos, capítulos (1 e 2) e conclusão geral. A introdução geral abordou aspectos sobre massa óssea e composição corporal, assim como os respectivos e principais estudos na área. Nos capítulos 1 e 2 encontram-se os artigos formatados segundo as normas específicas de cada periódico a que foram submetidos. Na conclusão geral foram apresentadas as principais conclusões dos dois artigos. As referências bibliográficas foram apresentadas no final de cada capítulo e da tese. A seguir, foram apresentadas as principais informações que se referem à estruturação dos dois capítulos da tese. Objetivo: Os objetivos do presente estudo foram: (1) avaliar as alterações na quantidade óssea em relação à idade, peso, altura, índice de massa corporal, nível socioeconômico e estadio puberal em estudantes de baixo nível socioeconômico e (2) avaliar a influência da composição corporal sobre a massa óssea em crianças e adolescentes. Materiais e Métodos: Participaram do estudo 270 estudantes saudáveis de baixo nível socioeconômico, de ambos os sexos com idades entre 7 e 19 anos. Por métodos antropométricos foram avaliados o peso e a estatura e calculados o índice de massa corporal (IMC), massa gorda, índice de massa gorda e percentual de gordura corporal, circunferência da cintura e do quadril e a relação cintura-quadril. A quantidade óssea (Amplitude Dependent Speed of Sound, AD-SoS) foi avaliada por meio de transmissão de sinais de ultrassom nas falanges utilizando-se a terceira geração do equipamento DBM Sonic BP (IGEA, Carpi, Italy). Para cálculo do z escore da AD-SoS foram usados a média e o desvio-padrão para idade e gênero de acordo com dados presentes no software do aparelho. Foi realizada a análise descritiva dos dados, e aplicaram-se os testes de Wilcoxon, Mann-Whitney, coeficiente de correlação linear de todas as idades e ambos os sexos. Em ambos os sexos AD-SoS apresentou Spearman e análise de regressão linear múltipla stepwise com significância de 5%. Resultados: No estudo longitudinal, observou-se que meninos e meninas apresentaram em geral ganho significativo de peso, altura e IMC, porém com diminuição da AD-SoS entre os meninos mais jovens e as meninas mais velhas. Porém, o z escore da AD-SoS girou em torno de zero na segunda avaliação para correlações significativas com idade, peso e altura, e IMC após um ano nos meninos e nas duas avaliações nas meninas, sendo a idade a única preditora nos meninos nas duas avaliações, e a idade, a altura, o estadio púbere e o IMC preditores na primeira avaliação, e a idade, o estadio púbere e o IMC preditores na segunda avaliação para as meninas. No estudo transversal, observou-se que as meninas apresentaram maior massa óssea em relação aos meninos com o avanço da idade e do estadio puberal. Em ambos os sexos, a massa óssea apresentou correlações significativas com idade, peso, altura, IMC, circunferência da cintura e quadril; com massa gorda, índice de massa gorda e percentual de gordura corporal apenas nas meninas; e correlação negativa com a relação cintura-quadril em ambos os sexos. A idade e a altura foram preditoras nos meninos e a idade, o estadio púbere e o índice de massa gorda preditores nas meninas. Conclusão: Apesar do aumento do peso, da altura e do avanço do estadiamento puberal, após um ano de acompanhamento não ocorreu um ganho proporcional de massa óssea neste grupo de estudantes de baixo nível socioeconômico; e a correlação entre massa óssea e composição corporal ocorreu em ambos os sexos, porém, apenas nas meninas, o índice de massa gorda foi preditor da massa óssea. / Abstract: Structure of the thesis: In this study we opted for the "Scandinavian Model", which is called "Alternative Model" in the Post-Graduate Program of Child and Adolescent Health of the Faculty of Medical Sciences, at State University of Campinas (FCM - UNICAMP). Thus, the thesis was composed of general introduction, objectives, chapters (1 and 2) and general conclusion. The general introduction approached aspects on bone mass and body composition as well as the major studies in the area. Chapters 1 and 2 contain the articles formatted according to the specific rules of the journals to which they were submitted. In general conclusion we presented the main conclusions of the two articles. References were presented at the end of each chapter and of the thesis. Next, we present the main information that refers to the structuring of the two chapters of the thesis. Objectives: The objectives of this study were: (1) to evaluate changes in bone density for age, weight, height, body mass index, socioeconomic status, and pubertal stage in Brazilian students from low socioeconomic status and (2) to evaluate the influence of body composition on the bone mass in healthy students of low socioeconomic status. Materials and Methods: The study included 270 healthy students of low socioeconomic status, of both genders aged 7 and 19 years. Anthropometric methods, weight and height, were obtained to calculate the body mass index (BMI), fat mass, fat mass index and percentage body fat, waist and hip circumferences were also obtained and the waist-hip ratio was calculated. The bone quantity (Amplitude Dependent Speed Sound, AD-SoS) was evaluated by means of signal transmission of ultrasound at the phalanges using the third generation of DBM Sonic BP device (Igea, Carpi, Italy). To calculate the z score of the AD-SoS, the mean and standard deviation for age and gender according to data on the device software were used. A descriptive analysis of the data was performed, followed by the Wilcoxon and Mann-Whitney tests, correlation coefficient and Spearman's analysis of stepwise linear regression with a AD-SoS among younger boys and older girls. However, z scores of AD-SoS was around zero in the second assessment for all ages and both genders. In both genders AD-SoS was significantly correlated with age, weight and height, and BMI after one year in boys and girls in both evaluations. Age was the only predictor among boys in both evaluations. Among girls, age, height, pubertal stage and BMI were predictors in the first evaluation, and age, pubertal stage and BMI in the second. A cross-sectional study showed that girls had higher bone mass than boys with advancing age and pubertal stage. In both sexes, bone mass was significantly correlated with age, weight, height, BMI, waist circumference and hip. Correlation with fat mass, fat mass index and percentage of body fat was observed only in girls, and there was negative correlation with waist -hip in both genders. Age and height were predictors for boys and age, pubertal stage and fat mass index predictors for girls. Conclusion: Despite the increase in weight, height and advancement of pubertal stage, after a year of monitoring there was not a proportional gain of bone mass in this group of Brazilian students from low socioeconomic level; and girls tended to have higher body fat and higher bone density compared with boys, with a contribution of adiposity on bone density for the group of girls. significance of 5%. Results: In a longitudinal study, we observed that boys and girls showed a significant gain in overall weight, height and BMI, but with reduced. / Doutorado / Saude da Criança e do Adolescente / Doutor em Ciências

M.Phil. (Anthropology) / The primary aim of this study was to undertake the description and analysis of the manual and pedal hominin phalanges from Drimolen, South Africa. The specimens were contextualized by examining their counterparts in a series of extant and extinct specimens. As Drimolen preserves the remains of both Paranthropus robustus and early Homo, it provides an opportunity to contribute to our understanding of morphological variation and differences between these taxa, as well as providing an important first step in conceptualizing their evolutionary history and palaeobiology. The first section focused on the manual and pedal phalanges, while the second focused exclusively on the first metatarsal. Numerous studies have analyzed Plio-Pleistocene manual and pedal phalanges to evaluate tool-related behaviours and locomotion in early hominins. In this dissertation nine phalanges were described and analyzed for the first time. The manual specimens consist of one proximal (DNH 9), two proximal pollical (DNH 116 and DNH 119), four intermediates (DNH 48, DNH 63, DNH 65 and DNH 66) and one distal pollical phalanx (DNH 13). There is currently only one pedal proximal phalanx (DNH 117). As at Swartkrans, assignment of postcranial elements was hampered by the fact that two hominin species have been found at the site, namely Paranthropus robustus and early Homo. To analyze the specimens, multivariate statistics (PCA and CVA) were conducted on the specimens using raw and size-adjusted data. This was done within the context of a large extinct and extant dataset to compare size and shape data. In general, PCA and CVA yielded similar results but only the raw data was useful in discriminating between taxa. There was poor discrimination in the analyses based upon size-adjusted data because of the huge degree of overlap between fossil and extant taxa. Consequently, results were not diagnostic and it wasn’t possible to assign specimens confidently to either Paranthropus or Homo. This was exacerbated by the isolated nature of the remains, the presence of two hominin taxa and taxonomic uncertainties of several Swartkrans phalanges. Despite these difficulties, these specimens do provide insight into the degree of morphological variation present in the phalanges from the Plio-Pleistocene of South Africa. The second section described the fragmentary first metatarsal and quantified it by using laser scanning and calculating the curvature of the proximal articular surface. Univariate statistics were then calculated in order to examine the degree of curvature between each of the extant taxa and whether these differences were statistically significant. Finally, a simple bivariate plot was generated using the curvature results which showed that this joint surface was most curved in chimpanzees and western gorillas, moderately curved in eastern gorillas, and flattened in modern humans and baboons. Highly curved joint surfaces in this region suggest a more mobile hallux, whereas flattened surfaces suggest reduced joint mobility. The fossil specimens SK 1813, STW 573, STW 595 and OH-8 all grouped closely with modern humans; A.L. 333-54 and SKX 5017 grouped with chimpanzees, while DNH 115 grouped with eastern gorillas. Overall, these results indicate that SKX 5017 was the most curved of the South African specimens and is attributed to Paranthropus (Susman, 1988). It grouped closely with DNH 115 which suggested that climbing activities may have continued to play an important role in the behavioral repertoire of these individuals during the Plio-Pleistocene.

The subject of this study is the exploitation of marrow in European elk (Alces alces), at two Stone Age settlements in northern Sweden. The bone material presented in this study originate from Bellsås in Jämtland county, and Bastuloken in Västernorrland county. Only bones containing white marrow have been analysed: the mandibula, the long bones, and the first and second phalanges. This study aims to understand if, and how the extraction and use of bone marrow varied between the two sites. Is there a difference in which elements that were chosen for exploitation between the two sites? What can differences in the choice of elements for marrow extraction tell us about changes in local preferences and alterations in practises over time? Can the stone material from the two sites in combination with the bones give any clue to how the localities were used? The results of this study shows that the difference in marrow exploitation between the two sites lies mainly in the choice to exploit phalanges as a source for marrow at Bastuloken but not at Bellsås. The reasons for this are discussed and the conclusion is that cultural choices or preferences, rather than nutritional stress, are the cause for the choice to use these elements as a source for marrow. The bone and stone material in combination show that the two localities have been used in different ways.

Uppsatsen undersöker björnklor upptäckta i järnåldersgravar (ca 500 e.Kr. – 1100 e.Kr.) på Gotland, Sverige. Brunbjörnen har aldrig funnits som en del av i öns fauna, vilket innebär att varje björnklo som upptäcks är ett spår av ett forntida utbyte mellan ön i fråga och omgivande fastlandsområden. Tidigare forskning inom ämnet har mest bestått av sammanställningar av gravkontexter med björnklor. För att ytterligare tolka björnklorna och för att diskutera det möjliga syftet bakom deponeringar i gravar behöver emellertid klor knytas till tillhörande tassar. En vanlig förklaring är att björnklor härstammar från pälsverk. Teorin om päls fungerar dock inte för alla upptäckta klor. Därför syftar uppsatsen till att skapa en metrisk metod genom mätningar av referensmaterial av björnklor. Tanken är att mätmetoden ska användasför att undersöka och tolka arkeologiska fynd av björnklor. Tolkningen av klorna är en viktig del i förståelsen om hur djurresurser nyttjades under förhistorisk tid. / This paper examines bear claws discovered in Iron Age graves (c. 500 AD – 1100 AD) in Gotland, Sweden. The brown bear has never existed as a part in the island's fauna, meaning that every bear claw discovered is a trace of the ancient exchange between this island and the surrounding mainlands. Previous research on the subject has mostly consisted of compilations of the number of grave contexts with bear claws. However, to further interpret bear claws from each burial context and to discuss the possible purpose behind deposition in the grave, claws need to be assessed for associated paws. A common explanation is that bear claws derives from fur. However, the theory of fur does not work for all discovered claws. Therefore, the paper aims to create a metric method through measurements of reference material of bear claws. The idea is that the measurement method could be used to examineand interpret the archaeological bear claws. The interpretation of the claws is an important part of the understanding of how animal resources were used in prehistoric times.

Some breeds of cattle and buffaloes still require determinations of these values for the digits. Thus, the objective with this research was to compare and correlate the condyles and phalanges, on radiographic images, and measurements of internal and external structures of the hoof, using computed tomography, to buffaloes and cattle breeds Nelore, Curraleira and Pantaneira. After submission and approval of the project by the Ethics Committee in Research of UFG, Protocol No. 090/2011, 114 were used digits of the locomotor members cattle and buffaloes without lameness in foot. Members were collected from an abattoir under Federal Inspection, disarticulated joints carpal/metacarpal and tarsal/metatarsal and by lot were used only thoracic and left pelvic limbs. For radiographic placements used were dorso-palmar/plantar and members of the CT scans were positioned with the palmar or plantar portion of the table CT scanner and the images obtained by transverse sections. From the radiographic images was measured the length of the condyles, proximal, middle and distal phalanges and the entire condyle and digit together. CT measurements were carried out: thickness of the sole; distance between the inner wall of the sole the distal phalanx; distance between the inner wall of the hoof the distal phalanx; thickness of the wall hoof; base length of the distal phalanx; side length of the distal phalanx; height of the distal phalanx, length of the sole; length of the dorsal hoof wall; heel depth, angle between the lengths of the wall and the sole length and angle between the side and base of the distal phalanx. To compare the means between the races was used the Tukey test (p<0.05). The Pearson correlation was performed between the weight and all measurements and multivariate analysis tested the similarity of the groups. The results of radiographic verified for the buffaloes, the greater length of the proximal phalanx in forelimbs (Lateral: 6.28 ± 0.13; Medial: 6.31 ± 0.18) and the hindlimbs (Lateral: 6.48 ± 0.15; Medial: 6.38 ± 0.17). The lengths of these phalanges did not differ (p> 0.05) between the Pantaneiro and Curraleiro digits in the forelimbs. In CT scans measures the length of the base (Lateral5.58 ± 0.18; Medial 6.52 ± 0.32 / Lateral:5.39 ± 0.09; Medial:6.43 ± 0.18) length lateral (Lateral:5.44 ± 0.21; Medial:6.02 ± 0.24 / and Lateral:5.3 ± 0.17; Medial:6.07 ± 0.27) and height (Lateral: 3 , 98 ± 0.16 and Medial: 4.15 ± 0.12 / Lateral:3.93 ± 0.11; Medial:4.01 ± 0.12) of the distal phalanx, had the highest measured in buffalo and did not differ (p> 0.05) between breeds of cattle. Thus, we conclude that the buffaloes have larger dimensions of the condyles and phalanges. In tomographic imaging, measures the hoof were similar between Nelore and Curraleiro in forelimb and between Curraleiro and Pantaneiro in the hindlimb. / Exames radiográficos e tomográficos podem colaborar para o diagnóstico e prognóstico de enfermidades podais fundamentados no conhecimento de valores morfométricos referenciais. Várias raças de bovinos e a espécie bubalina ainda necessitam das determinações desses valores para os dígitos. Com isso, o objetivo com esta pesquisa foi comparar e correlacionar as medidas dos côndilos e falanges, em imagens radiográficas e as medidas das estruturas internas e externas dos cascos, em imagens tomográficas, para búfalos e bovinos das raças, Nelore, Curraleira e Pantaneira. Após submissão e aprovação do projeto pelo Comitê de Ética em Pesquisa da UFG, protocolo Nº 090/2011, foram utilizadas 114 extremidades distais dos membros locomotores de bovinos e bubalinos sem enfermidades podais. Os membros foram colhidos em frigorífico, sob Inspeção Federal, desarticulados nas junções carpo/metacarpo e tarso/metatarso e, por sorteio, foram utilizados apenas membros torácico e pélvico esquerdos. Para os exames radiográficos, os posicionamentos utilizados foram o dorso-palmar/plantar e para os exames tomográficos os membros foram posicionados com a porção palmar ou plantar sobre a mesa do tomógrafo e as imagens obtidas em cortes transversais. A partir das imagens radiográficas foram mensurados o comprimento dos côndilos, das falanges proximal, média e distal e de todo o dígito e côndilo juntos .As mensurações tomográficas realizadas foram: espessura da sola; distância entre parede interna da sola-falange distal; distância entre a parede interna do casco-falange distal; espessura da parede do casco; comprimento da base da falange distal; comprimento lateral da falange distal; altura da falange distal; comprimento da sola; comprimento da parede dorsal do casco; profundidade do talão; ângulo entre os comprimentos da parede e da sola e ângulo entre os comprimentos lateral e da base da falange distal. Para a comparação de médias entre as raças foi utilizado o teste de Tukey (p&#8804;0,05). A correlação de Pearson foi realizada entre o peso e todas as mensurações e a análise multivariada testou a similaridade dos grupos. Nos resultados dos exames radiográficos, verificou-se para os búfalos, maior comprimento de falange proximal, tanto nos membros torácicos (Lateral:6,28±0,13; Medial:6,31±0,18) quanto nos membros pélvicos (Lateral:6,48±0,15; Medial:6,38±0,17). Os comprimentos dessas falanges não diferiram (p>0,05) entre as raças Curraleira e Pantaneira nos dígitos dos membros torácicos. Nos exames tomográficos, as medidas do comprimento da base (Lateral:5,58±0,18 e Medial:6,52±0,32 / Lateral:5,39±0,09 e Medial:6,43±0,18), comprimento lateral (Lateral:5,44±0,21 e Medial:6,02±0,24 / Lateral:5,3±0,17 e Medial:6,07±0,27) e altura (Lateral:3,98±0,16 e Medial:4,15±0,12 / Lateral:3,93±0,11 e Medial:4,01±0,12)da falange distal, apresentaram as maiores medidas em búfalos e não diferiram (p>0,05) entre as raças de bovinos. Diante disso, conclui-se que os animais da espécie bubalina apresentam as maiores dimensões de côndilos e falanges. Em imagens tomográficas, medidas dos cascos foram similares entre as raças Curraleira e Nelore no membro torácico e entre Curraleiro e Pantaneiro no membro pélvico.
