LIVEWEIGHT GAIN IN ZABAIKALSKAYA YOUNG HORSES AND THEIR HYBRIDS WITH RUSSIAN DRAFT HORSES
Abstract
Results are given from a comparative study on liveweight gains in the young stock of horses of different genotypes. The study was conducted in 2012–2015 on two groups of young horses: purebred Zabaikalskaya and their hybrids with Russian Draft horses. The live weights of foals were monitored by weighing them in third day after birth, at 6, 12, 18, 24, and 30 months of age. The live weights at birth in hybrid foals ranged from 38 to 44 kg, in native Zabaikalskaya foals from 38 to 42 kg. The maximum liveweight gain was observed in the period from birth to 6 months of age, where the highest parameters were recorded in hybrid foals. In this period, Russian Draft horse hybrids had the average liveweight gain of 185.1 kg, native Zabaikalskaya horses 170.5 kg. The difference in gains made up on average 14.6 kg, or 8.56 percent. During subsequent age periods, superiority of hybrid foals over Zabaikalskaya ones in live weight remained. The foals’ ages of 12 and 24 months were for winter keeping and insufficient feeding and severe climatic conditions. In connection with that, a reduction in live weight, as compared to that at 6 and 18 months of age, was observed in both hybrids and native horses. The animals of the experimental groups had rather high average daily liveweight gains even in the absence of extra nutrient. During this period, draft horse hybrids also exceeded native horses in the average daily liveweight gain by 79.8 g, or 8.5 percent.
