Development of marble beef technology

Abstract

Marble beef technology was tested on the bulls of Kazakh white breed (Zavolzhsky type), because they have genetic predisposition to formation fatty streaks. For the experiment 3 groups of 10 calves of the age of 10 months were formed. The experiment lasted for 8 months. The calves of the control group received basic feed, I group - at the basic diet were 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 of the marble beef technology evaluation of the exterior and dynamics of the daily gain of animals was carried out. Varietal composition of the carcass, deposition, localization, and the quality of adipose tissue were assessed. Analysis of the data has revealed that introduction into feed the cattle cake and fuzz of pumpkin seeds allows to increase by 29.8 kg gain and obtain beef of A3 category by the standard B.M.S. (Beef Marbling standard).
