Zlochevs'kyj M. Biotechnology of obtaining and use of exogene immobilized glucoamylase for feeding yong cattle

Glucoamylase G20x, young cattle. Glucoamylaseenzyme stability increase elaboration ways by mean of absorptive immobilization on the zeolite and airpower as the bearers. Investigation on the received biocatalyst efficiency for feeding calves. Immobilization methods, catalytic activity determination, making zootechnical experiments and biochemical investigations. Spectrophotometr, ohmmetr. Immobilized enzyme keeps quite significant catalytic activity (64-68,2%) and is stable against the influence of the pH environment in a wide range (рН 1,5-8,0). Calves( ration inmixen is contributing their productivity increase by 10-21,1%. The cataiyst of prolonged action was received for the first time, its efficiency use was established in feeding yuong cattle. There were elaborated the recommendation for its use in animal husbandry. The methodical recommendations for conducting instruction on biotechnology for the students of zootechnical faculty and for veterinary medcine traning
