THE DEPENDENCE OF MILK PRODUCTIVITY OF HOLSTEIN COWS ON LIVE WEIGHT IN EXPERIMENTAL

This article provides information on the feeding conditions of red-and-white Holstein cows at the "Abdumalik Ota Vorislar" breeding farm in the Bakhmal district of the Jizzakh region. A group of Holstein cows with different live weights was monitored throughout a lactation period, with systematic recording of milk output and body condition. Statistical analysis revealed a moderate to strong positive correlation between higher live body weight and increased milk yield, though with diminishing returns beyond a certain threshold. The findings suggest that optimal weight management plays a crucial role in maximizing the dairy performance of Holstein cattle. These results can serve as practical guidance for breeders and farm managers seeking to improve herd productivity through targeted feeding strategies and selection protocols.
