| Abstract | The paper presents research materials on the use of heifers udder massage and the subsequent milk productivity of first-calf cows. Studies have shown that for first-calf cows (?ommercial dairy farm No. 1, vil. Kezdur), they were given manual udder massage. Milk yield for 305 days of lactation averaged 5111.6?41.80 kg; the content of the mass fraction of fat in milk 3.59?0.05%; the content of the mass fraction of protein 3.19?0.01%. In first-calf cows (?ommercial dairy farm No. 3, vil. Pazhman), that were given mechanical udder massage. Milk yield for 305 days of lactation averaged 5272.6?262.13 kg; the content of the mass fraction of fat in milk 3.55?0.04 %; the content of the mass fraction of protein 3.18?0.01 %. In first-calf cows (?ommercial dairy farm No. 2, vil. Klyuchevskaya), that were not given udder massage. Milk yield for 305 days of lactation on average for the study group was 4794.6?87.30 kg; the content of the mass fraction of fat in milk 3.52?0.18 %; the content of the mass fraction 3.18?0.02 %. In first-calf cows (?ommercial dairy farm No. 4, vil. Kamyshevo), which also were not given udder massage. Milk yield for 305 days of lactation of the studied cows averaged 4858.8?71.02 kg; the content of the mass fraction of fat in milk 3.48?0.18 %; the content of the mass fraction of protein 3.18?0.03 %. |
