COMPARISON OF THE ECONOMIC AND USEFUL CHARACTERS OF PRIVESTIES OF THE SUMS DOMESTIC BREED TYPE OF THE UKRAINIAN BLACK AND BROWN DAIRY AND UKRAINIAN BROWN DAIRY BREEDS
Abstract
The breed factor has a significant impact on indicators of milk productivity of cows. Of particular interest is the study of milk productivity indicators of cows of new domestic dairy breeds, created on the basis of the mother of one local breed. An example of such breeds can be the Ukrainian brown dairy breed and the Sumy intrabreed type of the Ukrainian black and spotted dairy breed, which were created on the basis of the Lebedin breed. To fulfill the goal, research was conducted at the state breeding plant of the State Enterprise "Experimental farm of the Institute of Agriculture of the Northeast of the National Academy of Agrarian Sciences of Ukraine", Sumy district, on the first-borns of the Ukrainian brown dairy breed and the Sumy inbred type of the Ukrainian black-spotted dairy breed. Milk productivity was assessed by monthly control milkings with milk sampling. A counter – indicator IU-1 was used to take milk samples. The content of milk components was determined in the laboratory of the Institute of Animal Husbandry of the National Academy of Sciences by the method of infrared photometry on the equipment of the corporation "Bentley Instruments" (USA). The content of somatic cells in the milk of cows was determined by the method of laser flow cytometry, using the "Somacount 150" counter of the specified laboratory equipment. As a result of the conducted research, it was established that according to the average amount of milk yield, the amount of milk fat and protein, black-spotted littermates prevailed over brown littermates. No probable difference was found in the content of fat and protein in milk. The interbreeding differentiation based on the dynamics of changes in milk components during lactation was established. The fat content during lactation changed in a wave-like manner, the protein content had a clear tendency to gradually increase, starting from the third or fourth month of lactation. The content of dry matter and dry skimmed milk residue gradually increased from the beginning of lactation. The average number of somatic cells in milk did not exceed 200,000 cm3. Along with indicators of milk productivity, indicators of reproductive capacity were studied. According to them, the animals of both breeds met the desired values and characterized the animals of both studied breeds as meeting the standards of the breeds in terms of growth and development. Animals of the Sumy inbred type of the Ukrainian black and spotted dairy breed had lower values of the age of first insemination and calving.
