The effect of dry poultry litter on growth and feed utilisation in rats

In the conducted studies, the effect of dry bird droppings (SPP) on growth and feed use in rats was studied. The scientific and laboratory experiment was performed in the conditions of the experimental veterinary clinic (vivarium) of the Kazan state medical University IN 2019. 4 experimental groups of laboratory rats were formed using the method of par-analogs: one control group and three experimental groups with 5 heads each. Control group rats were fed a basic diet based on a wheat-barley-oat mixture. Rats of the I-th, II-th, III-th experimental groups also received the main diet, but in it, respectively, 10, 20 and 30% of the grain mixture was replaced by a similar amount of SPP. It was found that during the accounting period of xperimental feeding, the growth energy of rats of the I-th, II-th, III-th experimental groups was higher by 44.61%, 55.38% and 28.37%, and the feed consumption per unit weight gain is less by 34.01; 22.96 and 14.90 %, respectively, compared with control animals.
