The results of the research work: - according to the results of regression analysis, it was established that the selection of Holstein dairy cattle to increase protein milk yield should be continued, as selection for fat milk production will significantly reduce the protein content in milk; - live weight of heifers and body structure measurements partially influenced the sex of the offspring during the 1st calving - bulls were more often born to first-borns who had a higher live weight at the age of 9-18 months and larger linear body structure measurements, which agrees with the Trivers hypothesis. Willard; - estimates of individual heterozygosity for 10 loci of MS-DNA and mean multilocus estimates of d2 were weakly related to the live weight of heifers of the southern meat breed; - the correlation between heterozygosity and signs of reproduction of sows of large white breed had a negative sign, that is, we are dealing with the manifestation of negative cases of HFCs; therefore, care should be taken when mating animals of different origins (English and Hungarian selection) to avoid outbred depression; - 3-4-year cycles of fluctuations in live weight of piglets, due to the duration of productive life of the main livestock in the farm; the live weight of piglets at birth showed a probable effect of climatic conditions of the month preceding farrowing, while the live weight at weaning of the influence of climatic conditions was not recorded; - both the number of farrowing and the size of the nest at birth show a compensatory effect in the formation of quantitative characteristics of stillbirth in sows Product Description popup.authors Atamaniuk Ihor P Kramarenko Olexander S.
