Efficiency of Chickens-Broilers Rearing under Floor and Cage Indoor Treatment
When rearing chickens in a period from 0 to 14 days, experimental and control groups were given the compound feed of the recipe PK- 5-1-140. They also got 1% of hydrolyzed serum enriched by lactates, which contained 40% of dry matter. Its active acidity was 6.4 рН. The content of milk acid was 3.5 g, glucose - 3.5 g, and lactose - 2 g. At this age period the content of the compound feed included 69.4% of wheat without corn, and the exchange energy was 99.2 kkal. In the second period of rearing from 14 to 28 days, the chickens-broilers were fed with the compound feed of the recipe PK-5-2-133 which contained 40% of wheat and 33.3% of corn, and the power food value of day's ration was 324.7 kkal. In the third period of rearing from 28 to 42 days, the chickens were given the compound feed of the recipe PK-6-П-139, which included 66.6% of wheat without corn, and its food value in day's consumption was 476.22 kkal of the exchange energy. Getting the compound feed with addition of hydrolyzed serum enriched by lactates in the dose of 1%, the chickens-broilers in different age periods activated the palatability of the fodder. During the experience, it was found that when keeping the chickens-broilers in cages, the body weight was higher by 8.9 and 8.3% at the end of the rearing period in comparison with analogue chicken groups under the floor indoor treatment. There was no great difference between the feed expenses per 1 kg of the weight gain under the floor and cage indoor treatment (2.25-2.40 kg).
