Efficiency of Boars of Specialized Meat Breeds When Crossed with Sows of Large White and the Belarusian Meat Breeds
Abstract
The experiments helped to determine that the use of boars of meat type efficiency when crossed with sows of Large white and Belarusian meat breeds the heterosis effect of multiple pregnancy, compared with control groups amounted 5,2-8,0 %, the number of piglets, the litter weight to weaning increased by 2,0-4,4 %. The use for crossing of Duroc brred boars leads to a decrease in multiple pregnancy of sows of experimental groups at 0,95-1,35 animals.For fattening productivity two optimal variants of Belarusian meat breed sows crossingwith Duroc boars and Landrace boars were determined, providing high average daily weight gains (767-785 g) at a low feed cost (3,32-3,51 f.u.).Two-breed crosses of all experimental groups: LWxD, LWxL, BMxL, BMxD and LWxBM, characterized by high meatiness of carcasses (60,4-63,6 %), a large area of “muscular loin” (33,8-40,2 cm2), heavy ham (10,8-11,3 kg), which meets the requirements of present-day technology of pork production in industrial conditions.
