The work was carried out in the Seed Laboratory of the Agronomy Department, in the Cerrado Biomass Laboratory of the Department of Nutrition and in the Laboratory of Plant Anatomy of the Department of Biological Sciences of the Federal University of the Jequitinhonha and Mucuri Valleys - UFVJM, Diamantina, MG. Seeds of CNPA G2 (lot 1) from the 2010 crop, CNPA G3 (lot 2) from the 2010 crop, CNPA G4 (lot 3) from the 2014 crop and BRS Silk (lot 4) from the 2015 harvest were used, provided by Embrapa Algod?o ? Para?ba and safflower grains purchased from the company Terra dos P?ssaros, harvest 2015. To characterize sesame and safflower seedlings, analysis was conducted for the variables moisture level, germination, first germination count, speed index, emergence, initial booth, emergence speed index. In order to ascertain the sanitary quality of the lots, a sanitary test was performed. The determination of the centesimal composition of the sesame and safflower seeds was also carried out. For the morphological characterization of seed and seedlings the biometric aspects were evaluated and the characteristics of their structures were analyzed. In addition, the studies of seed image analysis, the anatomical characterization, were carried out. In addition, the studies of image analysis were carried out with the help of the SAS System and the anatomical characterization. It was concluded that the sesame seed lots presented similar physiological quality and that part of the physiological quality may have been affected by the presence of pathogens in the lots. The centesimal composition confirmed the species as oleaginous. The image analysis allowed to verify characteristics for the distinction between the lots of sesame seeds. Anatomical analyzes between batches were similar. It was verified that the low rate of germination of safflower grains is due to sanitary quality. It has been found that safflower grains are high in fiber.

Walp) ? uma das principais culturas alimentares do nordeste brasileiro. No Rio Grande do Norte, o feij?o caupi, feij?o vigna ou feij?o macassar, como ? conhecido, tem grande import?ncia socioecon?mica como fonte de nutrientes na alimenta??o humana, com grande destaque entre os produtos agr?colas. Para melhorar a produtividade e resist?ncia contra pragas, duas cultivares foram desenvolvidas, exclusivamente pela EMPARN (Empresa de Pesquisa Agropecu?ria do Rio Grande do Norte), por melhoramento gen?tico. As amostras foram fornecidas pela EMPARN, sendo duas melhoradas (Potiguar e Riso do ano) e duas crioulas (Costela de vaca e Canapu). As sementes foram trituradas e transformadas em farinhas e com as amostras foram realizadas as determina??es de umidade e cinzas por m?todos gravim?ticos, lip?deos por extra??o com Soxhlet, fibras com determinador de fibras, carboidratos por diferen?a e minerais por ICP-OES, exceto o f?sforo analisado por UVvis. Os resultados mostraram um alto conte?do de fibras (55,55% e 55,32% amostras melhoradas e 50,04% e 50,32% amostras crioulas) e prote?nas (25,52% e 25,27% amostras melhoradas e 27,23% e 24,99% amostras crioulas). Comparando os resultados dos teores de minerais, as cultivares melhoradas se destacaram em rela??o a Ca, Co, P, Mg, Mo e Na. As cultivares crioulas apresentaram melhores resultados de Cu, Cr (baixo teor), Fe, Mn, Ni, K e Zn. Os resultados obtidos ser?o importantes em futuras pesquisas nutricionais e para constru??o de uma tabela brasileira de composi??o qu?mica de alimentos. / The cowpea (Vigna unguiculata L. Walp) is a major food crops in northeastern Brazil. In Rio Grande do Norte, the cowpea, vigna beans or cowpea, as it is known, has great socioeconomic importance as a source of nutrients in food, with great emphasis among agricultural products. To improve productivity and resistance to pests, two cultivars were developed exclusively by EMPARN (Agricultural Research Corporation of Rio Grande do Norte), for breeding. The samples were provided by EMPARN, two improved (Potiguar and Laugh year) and two landraces (Rib of beef and Canapu). The seeds were ground and made into flour samples and the determination of moisture and ash by gravim?ticos methods, lipids by Soxhlet extraction, fibers with determiner fiber, carbohydrates by difference and minerals by ICP-OES were performed except the match analyzed by UVvis. The results showed a high fiber content (55.55% and 55.32% and 50.04% improved samples and 50.32% creole samples) and protein (25.52% and 25.27% improved and 27 samples, 23% and 24.99% creole samples). Comparing the results of the mineral content, the improved cultivars stood out in relation to Ca, Co, P, Mg, Mo and Na. Creole cultivars showed better results for Cu, Cr (low), Fe, Mn, Ni, K and Zn. The results will be important in future nutritional research and to build a table of Brazilian chemical composition of foods.

The experiment was conducted in the physical area of the Study Group on Forage (GEFOR), located in the Academic Unit Specialized in Agricultural Sciences - Federal University of Rio Grande do Norte - UFRN in Maca?ba, RN, Brazil. We used 32 lambs SPRD, obtained from herds in the state, with liveweight (LW) of 24.5 kg were assigned randomly to four treatments consisting of tropical grasses, two cultivars of Brachiaria brizantha, Marandu and Piat?, and two of Panicum maximum, Aruana and Massai. The experimental area was 2.88 ha, divided into 4 paddocks of 0.72 ha, where each picket consisted of a farm and was divided into six plots of 0.12 ha, where the animals remained under rotational grazing. The period of adaptation to the pickets was seven days. At the beginning of the experiment the animals were weighed, identified with plastic earrings and necklaces colored according to the treatment, and treated against. The lambs were loose in the paddock at 8 am and collected at 16 hours, which returned to collective pens. During the time of grazing animals had free access to mineral supplement with monensin Ovinof?s ? and water. Before entering the paddocks of pasture were sampled to characterize the chemical composition. Every seven days occurred at weighing, with fasting, to monitor the weight development. Cultivars Marandu, Aruana, Piat? and Massai were grazed for 133, 129, 143 and 142 days, respectively, until the lambs reach slaughter weight. Arriving at 32 kg lambs were evaluated subjectively for body condition score by, passed through fasting period, diet and water for 16 hours were slaughtered. Measurements were made in the inner and outer casings in addition to subjective evaluations regarding muscling, finish and quantity of pelvic-renal fat, then each was divided longitudinally into two half-carcases and cuts were made in the commercial left half, and after heavy calculated their income. Between the 12th and 13th thoracic vertebrae, was performed a cut to expose the cross section of the Longissimus dorsi, which was drawn on the rib eye area (REA) in transparent film. Fat thickness and extent of AOL GR were determined using a caliper. A tissue composition was determined by dissection of the legs. Analyzes were performed physical (color, cooking loss and shear force) and chemical composition of meat (moisture, ash, protein and lipids) in Longissimus dorsi muscle. Grazing tropical grass Brachiaria brizantha cvs. Marandu and Piat? and Panicum maximum cvs. Aruana and Massai can be used for lambs SRPD in the rainy season, because not alter the physico-chemical and chemical composition of meat / Objetivou-se com este estudo avaliar a qualidade da carca?a e das caracter?sticas f?sico-qu?micas da carne de ovinos criados em pasto de Brachiaria brizantha e Panicum maximum. O experimento foi conduzido na ?rea f?sica do Grupo de Estudos em Forragicultura (GEFOR), situado na Unidade Acad?mica Especializada em Ci?ncias Agr?rias Universidade Federal do Rio Grande do Norte - UFRN, em Maca?ba, RN. Foram utilizados 32 cordeiros SPRD, obtidos de rebanhos do Estado, com peso vivo (PV) m?dio de 24,5kg, distribu?dos aleatoriamente em quatro tratamentos constitu?dos por gram?neas tropicais, sendo duas cultivares de Brachiaria brizantha, Marandu e Piat?; e duas de Panicum maximum, Aruana e Massai. A ?rea experimental tinha 2,88 ha, dividida em 4 piquetes de 0,72 ha, onde cada piquete consistia de uma cultivar e era dividido em 6 parcelas de 0,12 ha, onde os animais permaneciam sob pastejo rotacionado. O per?odo de adapta??o aos piquetes foi de sete dias. No in?cio do experimento os animais foram pesados, identificados com brincos pl?sticos e colares coloridos de acordo com o tratamento, e tratados contra endoparasitas. Os cordeiros eram soltos nos piquetes ?s 8 horas e recolhidos ?s 16 horas, onde retornavam ?s baias coletivas. Durante o tempo de pastejo os animais tinham livre acesso ao suplemento mineral Ovinof?s? com monensina e ?gua. Antes de entrarem nos piquetes eram colhidas amostras do pasto para caracteriza??o da composi??o qu?mica. A cada sete dias ocorriam ?s pesagens, com jejum pr?vio, para o acompanhamento do desenvolvimento ponderal. As cultivares Marandu, Aruana, Piat? e Massai foram pastejadas durante 133, 129, 143 e 142 dias, respectivamente, at? os cordeiros atingirem o peso de abate. Ao chegarem aos 32 kg os cordeiros foram avaliados subjetivamente quanto a condi??o corporal por meio escores, passaram por jejum de s?lidos, dieta h?drica durante 16 horas e foram abatidos. Foram feitas mensura??es internas e externas nas carca?as al?m de avalia??es subjetivas quanto ? musculosidade, acabamento e quantidade de gordura p?lvico-renal, depois cada uma foi dividida longitudinalmente em duas meias carca?as e foram feitos os cortes comerciais na meia carca?a esquerda, logo ap?s pesados e calculados seus rendimentos. Entre a 12? e a 13? v?rtebras tor?cicas, foi realizado um corte para expor a sec??o transversal do m?sculo Longissimus dorsi, sobre o qual foi tra?ada a ?rea de olho do lombo (AOL) em pel?cula transparente. A espessura de gordura da AOL e a medida GR foram determinadas utilizando-se de paqu?metro. A composi??o tecidual foi determinada atrav?s da disseca??o das pernas. Foram feitas as an?lises f?sicas (cor, perdas por coc??o e for?a de cisalhamento) e a composi??o centesimal da carne (umidade, cinzas, prote?na e lip?dios) no m?sculo Longissimus dorsi. Pastagem de gram?neas tropicais de Brachiaria brizantha cvs. Marandu e Piat? e de Panicum maximum cvs. Aruana e Massai podem ser utilizadas para cordeiros SRPD na ?poca chuvosa, pois n?o alteraram as caracter?sticas f?sico-qu?micas e composi??o centesimal da carne
