Results are given from studies on productive qualities of young first-generation hybrid sheep (1/2 Zabaikalskaya Fine-Fleece, Khangilskiy type, + 1/2 Kulundinskaya Fine-Fleece) under the age of 7 months. Studies were conducted at the breeding enterprise Tsokto-Khangil, Transbaikal Territory, using conventional methods accepted in zootechnics. Fertility, lamb-producing capabilities and safety of young stock were taken into consideration in studying reproductive abilities in ewes. The control group consisted of rams and ewes of the Khangilskiy type of Zabaikalskaya Fine-Fleece, the experimental group was made up of rams of Kulundinskaya Fine-Fleece and ewes of the Khangilskiy type of Zabaikalskaya Fine-Fleece. The ewes from the control group produced 132 lambs, or 125.7 percent, those from the experimental group 109 lambs, or 121.1 percent. The safety of lambs was 97.3 percent in the control group and 96.9 percent in the experimental group. At 4 months of age, the hybrid ram lambs were heavier than their analogs by 1.3 kg, or 6.3 percent (p<0.001), the hybrid female lambs by 0.7 kg, or 3.2 percent; at 7 months of age, by 4.6 kg, or 13.6 percent (p<0.001), and by 1.5 kg, or 4.9 percent (p<0.001), respectively. Carcasses of the hybrid rams were heavier by 3.7 kg, or 27.0 percent, with slaughter yield of 46.8 percent compared to 44.6 percent in the control group that was higher by 2.2 absolute percent. It has been found that the hybrid young stock somewhat exceeds the pure-bred analogs of the Khangilskiy type of Zabaikalskaya Fine-Fleece in growth energy and meat productivity.
