EFFECT OF FEEDING DIFFERENT DOSES OF TRITICAL GRAIN ON THE DEVELOPMENT OF RABBITS INTERNAL ORGANS

Abstract

The results of the study of the influence of Poliske 7 triticale grain for its addition into the standard granulated compound feed to replace cereal ingredients (barley and oats) at the rate of 100; 50; 25 and 12.5%, respectively are highlighted, in the I, II, III and IV research groups on the massometric indicators of the internal organs of young rabbits of the termon breed with the intensive technology of growing them for meat. It was established that feeding triticale grain as a part of a complete ration granulated compound feed in the period from 50 to 100 days of age to experimental groups of rabbits led to an improvement in the relative indicators of internal organs, compared to the control group. It was noted that the addition of triticale grain into the compound feed in the amount of 50 and 12.5% led to changes in the weight of internal organs, the weight of the stomach and the length of the small and large intestine sections compared to the control group, which may indicate a positive effect of triticale grain on young rabbits. The mass of the entire alimentary canal was 3.6% greater in the animals of the II experimental group compared to the control. The use of experimental compound feed in rations contributed to an increase in the weight of the empty stomach by 14.7% in rabbits of III and 11.2% of IV experimental groups, the weight of the small intestine with chyme in animals of II, III and IV experimental groups - by 19.6; 10.7 and 3.9% compared to the control, fat mass – by 7.4, respectively; 3.6 and 1.9%. Тriticale grain in the amount of 50 and 12.5% of the weight of the grain group contributed to the tendency to increase the edible body parts of young rabbits compared to the control. The weight of the cooled carcass of rabbits of all experimental groups increased by 9.6; 10.2; 3.4 and 14.7%. It should be noted that the mass of pulp in the carcasses of animals of the II and IV groups was higher by 11.1 and 1.5%, and the mass of internal fat was lower by 6.3 and 1.6% compared to the analogues, which indicates a positive the effect of feeding triticale grain as part of granulated compound feed. There was a tendency towards an increase in the weight ratio of the liver, lungs and heart of rabbits of all experimental groups compared to the control.
