Features of broilers live weight gain in case of using the biotechnological additive “Ares”

Abstract

   The main costs of livestock production, including poultry farming, are related with the feed. Therefore it is very relevant to increase digestibility of feed, apply compound feeds from cheap raw materials produced domestically without reducing of nutritional value, and fully provide the poultry with substances necessary for their normal life. It is possible to achieve with the application of new feed additives, including biologically active substances. As a result of the research it was found that all broiler chickens showed high parameters of body condition during the boilers growing. The chickens from the II experimental group, which received the additive “Ares” in amount of 0.6 g/kg of feed, showed the highest live weight gain. Lower values were observed among the chickens of I and III experimental groups. However, in terms of live weight gain at the age of 36 days, these chickens exceeded the normal value parameters of the cross and the results obtained in the control group. The increase in the average daily weight gains in the first and third groups was observed throughout the entire period of fattening, and a slight decrease was observed in the second group in the period from 24th to 31th day with a sharp surge of weight gain in the last period from 31th to 36th day.
