Qorako‘l qo‘ylarining biologik xususiyatlarining sut mahsuldorligiga ta’siri

Abstract

This article investigates the biological characteristics, live weight dynamics, and their effect on the milk yield of Karakul sheep of various color strains (black, blue, and sur) under the environmental conditions of the "Nurtilek-qoraozek" farm in the Qorao‘zak district of the Republic of Karakalpakstan. The study revealed noticeable variations in live weight and growth dynamics across color groups during pregnancy and lactation periods. Specifically, black Karakul ewes demonstrated significantly higher milk productivity during the one-month lactation period (averaging 0.73 L/day) compared to blue (0.69 L/day) and sur (0.63 L/day) ewes by 4.2–5.2%, highlighting the vital role of milk yield in lamb growth and vitality.
