Abstract
An experiment was conducted to determine development of muscle and marbling in Kazakh white-headed breed by feeding cake and fuzz of pumpkin seeds. For experiment were formed 3 groups at 10 calves age of 10 months. The experiment lasted 8 months. Calves of control group received basic feed, I group at the basic diet enhanced by 180 g of cattle cake, II 180 g fuzz of pumpkin seeds. The nutritional value of feed for testing calves was calculated to receive an average daily gain of live weight on the level of 1100-1200 g. The basic feed for testing calves depending on their age consisted from 2.0 to 3.5 kg hay of cereal and pulses, 9.0-15.0 kg of haylage, 3.1-4.0 kg compound feed and 0.4 kg molasses beet. For development marble beef technology was carried evaluation of exterior and dynamics the daily gain of animals. There were assessing varietal composition of carcass, the deposition, localization, and quality of adipose tissue. Analysis of the data revealed that introduction into feed the cattle cake and fuzz of pumpkin seeds allows to increase by 29.8 kg gain and obtain the beef of A3 category by standard B.M.S. (Beef Marbling standard). Using cake and fuzz of pumpkin seeds allows enhance development muscle and formation marbling in beef of Kazakh white-headed breed.
