ENZYME PREPARATION OF “KLERIZIM GRANULAR” IN THE FEEDING OF LAYING HENS REPLACEMENT

The article presents a review of literature data concerning the enzyme lysozyme and its use in animals feeding. The technique of experiment for the use of the enzyme lysozyme in the feeding of laying hens replacement was shown. The experiment was started on the farm of agricultural enterprise LTD "Eco-farm Zoria” in Sarata Region, Odessa Oblast. Replacement hens of Adlerska Silver breed at the age of 10 days were chosen as the object and 3 experimental groups: 1-control, 2 and 3 experimental, 50 heads in each were formed. The enzyme preparation under the trade name of "Klerizym granular" (CLERIZYM GRANULATE) was used for the experiment, which will be added to the complete feed for animals of 2 and 3 experimental groups at the dose of 0.3 kg/t and 0.4 kg/t respectively. The experiment lasted 140 days. During the period of research such indicators as live weight, absolute, average daily and relative gains, livestock's maintenance, feed costs as well as development of the digestive tract and the reproductive organs, morphological and biochemical blood indicators; economic efficiency at the end of research will be accounted. The purpose of scientific-economical experiment is to increase the body weight, absolute, relative and average daily gains of replacement laying hens, improving the safety of herds, reducing feed costs in farming. As a result of use in feeding of the enzyme preparation "Klerizym Granulate", it became known that the live mass of research chickens of the II and III group during all experience was higher on average than 2 and 3,8% in comparison with control. Also naturally the difference is traced in indicators absolute, average daily and relative additional weights. The maximum difference in indicators of absolute and average daily additional weights of live mass of research chickens I was at the age of 60 days which made 4,11 and 7,86% in comparison with control group. It has been established that use of the enzyme preparation "Klerizym Granulate" in feeding of repair young growth of laying hens positively influences their growth, the characterizing absolute and average daily additional weights of the II and III research groups. The maximum result was shown by the III research group, therefore the optimum norm of input of the enzyme preparation in a diet makes 0,4 kg on compound feed ton.
