Milk productivity and live weight of cows at ООО “PskovAgroInvest”

Abstract

Currently, the food problem occupies an important place among the global problems of mankind. Despite a slight increase in food production, the level of nutrition of the population is not reaching optimal levels. This is especially true for Russia. One of the ways to solve this problem is the development of agriculture, in particular animal husbandry. Over the five analyzed years, there has been an increase in the level of milk production in cows of all ages. Milk yield, fat and protein content in the milk of cows of all ages significantly exceed the breed standard. The live weight of cows of all ages for all years also significantly exceeds the breed standard, in particular, full-aged cows are characterized by a weight varying in the range of 599–606 kg. The fat content in milk of cows during this period ranges within 3.70–3.85% with a breed standard of 3.7%, protein content – 3.07–3.26% with a 3.0% breed standard, that is, exceeds the standard for the entire period taken into account. It should also be noted that every year there is an increase in indicators, reaching a maximum in 2020. It should be noted that a number of cows have been in the list of the best in OOO “PskovAgroInvest” for a number of years, improving their milk yield with each lactation. So, from Travinka 1330 in 2018, 10,573 kg of milk with a fat and protein content of 3.63% and 3.12% were milked, and in 2020 – already 11,239 kg with a fat and protein content of 3.71% and 3.18%; from cow Torpedo 234 the corresponding figures for the same years amounted to 9340 kg, 3.75%, 3.06% and 10,504 kg, 3.74%, 3.18% respectively.
