Abstract

The results of a detailed analysis of the productivity of cows of Ukrainian black and white dairy cattle, depending on the age and lactation are presented at the article. Found that 91% of cows are cows 1st–4th lactations: 1st – 31%, 2nd – 25% 3rd – 20%, 4th –15%. In terms of age make up 95% of cows are cows 2–8 years old: 2 years – 14%, 3 – 29%, 4 – 20%, 5 – 11%, 6 – 15%, 7 – 6 %, 8 – 4%; cows of age betwin 9 and 15 years old accounted for only 5% of the total number of cows. Established wide distribution ranges of age cows during lactation resulting increase in the duration of the service period. Marked increase in the average productivity of dairy cows from 1st to 3rd lactation followed by a sharp decline of 13.3% in the 4th lactation and gradually increase to 8th lactation. The highest maximum milk yield (9875 kg) set in cows 2nd lactation with a gradual decrease to the 7th (6380 kg). Established gradual increase in milk production of cows up to 3 years of age, followed by a sharp increase at 13.2% in the age of 4 years with a smooth growth to the age of 7 years, a decrease in the age of 9 years, the increase in the age of 11 years and a decrease in the age of 13 years. The maximum milk yielddepending on the age was highest in the age of 3 years (9875 kg) and gradually decreased to 7160 kg at the age of 9 years.
