Vyhodnocení reprodukčních ukazatelů ve vybraném chovu dojnic v ZOD "Podhradí" Choustník

NEZBEDOVÁ, Marie January 2017 (has links)
The aim of this thesis is to evaluate chosen influences on the extent of reproduction of randomly chosen milk cows that are bred in the same conditions. The chosen influences such as breed, age of the first calving, time of year of calving and level of yield were observed within breeds of Czech Fleckvieh and Holstein cattle. Evaluation was carried out in ZOD "Podhradí" Choustník company, specifically in Budislav farm. 191 cows were chosen for the basic sample. 95 of them were Holstein cattle and 96 were Czech mottled cattle. Chosen influences were evaluated according to data gained from the set of milk yield inspections. A statistically significant difference was observed between Czech ticks and Holstein cows in the length of service period per second and first lactation where Holstein cows have a second lactation period longer than 44 days (P <0.001). Evaluation of first calving age did not show any influence on the level of reproduction neither within Czech Fleckvieh nor within Holstein cattle. During the annual evaluation, it emerged that Holstein cows calved in spring and winter have significantly bigger insemination interval compared to cows that were calved during summer or autumn. This fact was also proven by correlation analysis. This analysis also confirmed the relation between annual period and insemination interval Rxy=0,21(P<0,05). The correlation analysis also proved the relation between annual period and service period as well as interim of Czech Fleckvieh cattle Rxy= 0,327 (P<0,01). Statistically significant influence was not proven within Holstein cattle. Correlation analysis only pointed out the relation between yield and service period Rxy=0,213 (P<0,05). Unlike Holstein cattle, gradual increase of service period figures and interim depending on yield was noticed. Breeding cows milking more that 7,5 thousand kg of milk per lactation had service period of 132 days (P<0,01) and interim 407 days (P<0,01). Economical losses caused by prolonged interim during monitored herd of cattle reached 400.490 CZK in year of 2016.

Faktory ovlivňující reprodukční ukazatele dojnic ve vybraném chovu

ZERZÁNKOVÁ, Veronika January 2019 (has links)
This thesis provides an overview of the literature on reproduction attributes of the Holstein Friesian cattle and its influence on the cattle reproductive indices. One of the goals was to evaluate the influence of selected factors on the reproduction indices for a pre-selected group of dairy cattles. The data has been processed and sorted by the lactation production levels, daily production, order of lactation and the age of the first calving. The data about the used bulls has been processed as well. Another goal of the thesis was acquisition of the data about excluded cows. For the excluded cows, the age, order of lactation, reason for exclusion and life-long production have been recorded. The data for the thesis have been obtained from the production control records and database of breeds in the selected Holstein cattle breeding. The dairy cattles, which got in calf during the years 2017 and 2018 have been evaluated. In particular, for 2017 and 2018, the evaluation was carried out on 190 and 229 dairy cattles respectively, which makes the total of 419 evaluated cows. For those dairy cows, the insemination index data, insemination interval, gestation after first insemination, service period and gestation period has been recovered from the zootechnical register. The evaluation of excluded dairy cows contained 339 dairy cows, which have been excluded during years 2017 and 2018. For the evaluation of the used bulls, the total count and description of how the bull for insemination have been selected is provided. Evaluation the influence of level of lactation production on the reproduction indices has shown a significant (p0,05) statistical relation between production levels and duration of the service period. It has also been proven that this has an influence on the insemination index levels. The lowest values (p0,05) of service period and insemination index have been detected for dairy cattles with production up to 6 999 kg. On the other hand, the highest values of service period and insemination index have been recorded for the dairy cattles with production up to 9 000 kg (p0,05). The influence of daily dairy production levels on the reproduction indices have been evaluated as well. It can be clearly seen from the results that as the daily dairy production increases, the service period increases as well. The lowest values (p0,05) of the service period was recorded for breeds, who had the daily production levels up to 24.99 kg. Opposed to that, the highest values of service period have been recorded for dairy cattles with average daily milk production over 30 kg. The evaluation of order of lactation on the reproduction indices did not show any significant statistical results (p0,05). Furthermore, during the evaluation of first calving, no statistically significant differences have been shown (p0,05). Last reproduction index we have evaluated was gestation after the first insemination. The groups were divided by the production levels, daily milk production, order of lactation and age of the first calving. For each group, the percentage of cattles that got in calf after first insemination has been computed. On average, this value was 36.28%.

Fázová výživa dojnic v daném zemědělském podniku

VACEK, Tomáš January 2019 (has links)
In this work, I analyzed phase nutrition dairy cattle practiced on a farm. Furthermore, the work focused on quality of bulky feeds from maize silage, grass-clover silage and field bean silage. Feeding method, composition of rations and production parameters were also evaluated, while taking welfare of the animals into account. For data analysis, a nutrition program was used. Indicators of nutritional values and fermentation characteristics, including microbiological testing of silage feeds (maize silage, grass-clover silage, field bean silage), correspond to a very good standard. For maize silage and grass-clover silage, NDV, ADV and NEL values were shown to be slightly below the national average. When evaluating the nutritional level based on the feed ration optimization, we can conclude that the differences in the monitored nutritional values are within the tolerance limits of the recommended values. The level of nutrition corresponds to the production achieved. Fat and starch content of the feed ration are consistent with the recommended values present in literature.

Ekonomická analýza plodnosti u stáda dojeného skotu

MAČLOVÁ, Jaroslava January 2019 (has links)
The aim of the work was to evaluate the milk production and fertility of the herd of Czech piebald cattle and to express the economic impact of the use of various breeding bulls used for breeding. The results of milk yield and insemination were evaluated in the years 2017 - 2018 for the last closed lactation sequence in the groups according to the order of lactation (1st lactation, 2nd lactation, 3rd lactation, 4th and next lactation). The indicators were evaluated for the three most commonly used breeding bulls. The average efficiency by the lactation sequence was in the 1st lactation 5143 kilogrammes of milk (P 0.001), the 2nd lactation 6520 kilogrammes of milk (P 0.01), the 3rd lactation 8186 kilogrammes of milk (P 0.001) and in the 4th and next lactation 7855 kilogrammes of milk. The efficiency of the whole herd was 6856 kilogrammes of milk contains 4.09% of fat and 3.46% of proteins. The avarige age at the first calving was 945 days, the length of the herd´s interval was 416 days, the insemination interval was 93 days and the service period was 129 days. The success rate of the 1st insemination in 2017 was 75%, in 2018 74%. The success rate of all insemination was 69% in both years. The costs of insemination of the whole herd with using all bulls in 2017 was 618 CZK and in 2018 was 577 CZK. Was found economic difference in using individual breeding bulls included in reprodudtion in a given herd.

Vybrané vlivy na růst telat masného skotu

TOMKOVÁ, Michaela January 2019 (has links)
The aim of this work was to analyze selected effects on the growth of calves of a selected herd of aberdeen angus cattle in Mýto farm in Hořice na Šumavě for the monitored period of 6 years (2012 - 2017). A total of 242 pure-bred calves of the aberdeen angus breed born during the reference period was included in the evaluation. Birth weight, weight at 120, 210 and 365 days were determined in calves. Subsequently, the group of calves was sorted by sex, year of birth, month of birth, birth order, father's individuality and mother's exterior. The data were statistically processed in Microsoft Excel and evaluated in Statsoft Statistica. When confronted with the national average published in the KUMP deadlines, the observed calves always had a lower birth weight, but higher weight at 120, 210 and 365 days. When evaluating the effect of the year of birth on calf growth, it was found that calves born in 2012 and 2013 achieved the best results. The best months for calving aberdeen angus breeds on the monitored breed were February to April. In terms of birth order, calves born to cows after the third calving achieved the best results. The worst results were achieved by calves from heifers and cows after the ninth calving. The best breeding-bull in breed regarding to the growth ability of calves was the sire ZAA 916. The PAA 027 sire showed the best results in terms of ease of delivery. There was no significant difference in the effect of maternal exterior on the growth ability of calves.

Vybrané vlivy na reprodukci plemenic holštýnského skotu

ŠPAČKOVÁ, Vladislava January 2019 (has links)
The work deals with the evaluation of selected effects on reproduction of Holstein cattle breeds. The aim of the study was to evaluate reproductive parameters (insemination index, insemination interval, period service, interim, pregnancy after the first insemination) in a selected group of dairy cows. These reproductive indicators were subsequently evaluated depending on genotype, performance level, lactation order and age at first calving and used synchronization methods. The evaluation took place at the Vřesce farm, belonging to company Rynagro a.s. 260 Holstein breed cows and their hybrids were included. The results showed that some reproductive indicators (insemination interval, service period and interim) of the monitored group of dairy cows were lower than the average of the Czech Republic. When evaluating the genotype effect on reproductive parameters, a highly significant effect (p<0.01) of genotype on insemination interval was found. Holstein breed cows had a 7-day higher insemination interval than other crosses. In evaluating the effect of daily milk yield was not proven statistically significant differences (p>0.05) in period servis and interim. Statistically significant differences (p<0.05) in insemination index, insemination interval and pregnancy after the first insemination were proven in the performance evaluation. The p-value of the global null hypothesis was close to 0.05 and no significant differences between the compared groups were demonstrated in the subsequent multiple comparison. The effect of the order of lactation on reproductive parameters was not proven (p>0.05). However, interesting results were found by the impact of age at first calving. There was a statistically highly significant difference (p<0.01) between the groups in the insemination interval and the interim and a statistically significant difference (p<0.05) between the groups in the service period. Cows with a first calving age 23 months had all of these indicators lowest, the highest values were found within cows with a first calving age of 28 months. After evaluating the correlation analysis, a significant effect of age at first calving on insemination interval (p<0.05; r=0.13), on interim (p<0.01; r=0.17) and period service (p<0.01; r=0.17). Synchronization methods were used in 125 cows and the overall success rate after this treatment was 47%. The most commonly used protocol was the Ovsynch method. The calculations based on the extension of the service period quantified the theoretical loss for the extended cycle of dairy cows. This loss is 7 030, - CZK per cow and takes into account the losses for milk and the unborn calf, not the cost of further insemination and treatment of cows.

Vliv polymorfismu kandidátního lokusu na technologické vlastnosti mléka

VAŇKOVÁ, Adéla January 2019 (has links)
The aim of this diploma thesis was to investigate the influence of milk betacasein locus (CSN2) polymorfic variants on production characteristics and milk technological qualities in Czech Simmental cattle and Holstein cattle. DNA extracted from milk of 702 cows was genotyped using PCR and RFLP methods. The genotypes A1A1, A1A2, and A2A2 had the following distribution within the population studied: A1A1 in 11,40 %, A1A2 in 8,46 %, and A2A2 in 50,14 % cows. The studied milk parameters were the milk yield (kg), protein and fat percentage and protein and fat yield (kg). The statistical evaluation was made STATISTICA 12 program. We found no statisticaly significant influence of CSN2 genotype on the selected milk yields. The results might be biased by the relatively low amount of individuals studied. Research will continue within the QJ1510339 and GAJU028/2019/ Z grant.

Kulturskolan – ett kommunalt ansvar och en nationell angelägenhet? : En kvalitativ analys av nationella och lokala kulturpolitiska diskussioner och beslut i relation till kulturskolan / The Swedish Community School of Art – Municipal Responsibility and National Corncern? : A qualitative analysis of national and local cultural policy discussions and decisions in relation to the community school of art

Söderberg, Erika January 2019 (has links)
The aim of this thesis is to investigate how the conditions for the Swedish community school of art is affected by how it is organized and by political discussions and decisions on a national as well as on a local level. Additionally, how this affects children’s accessibility to the school. A qualitative content analysis of political documents was implemented through a mixture of Dorte Skot-Hansen’s model and Per Mangset’s definitions of cultural political rationalities, with the aim to both distinguish different rationalities used for giving the community school of art legitimacy, as well as discern possible tensions between economical, administrative and creative cultural political rationalities. The results show that there are various opinions about whether or not there should be a national strategy for support of the community school of art. Furthermore, that municipals have differences and similarities between their community schools of art. In conclusion, these different opinions and local variations in conditions affect the school’s accessibility to children.
