Characteristics of some indicators of metabolism in the organism of the laying hens when included in the diets of calcium gluconate "Calcium Makg" and "Protical Tri Plus"

The authors investigated the influence of dietary supplements of calcium gluconate "Calcium MAKG" and "Protical Tri plus" indicators, characterizing the metabolism in the body laying hens. For the study were formed 4 groups of hens of cross "Lomann-brown-classic" at the age of 15 weeks on a 100 goals each. Dietary supplements were fed poultry in addition to the basic diet with 15 to 19 week of life. As biologically active additives in the first experimental group used the calcium gluconate in the dose of 615 g per 1 ton of feed, in the second experimental group -"Calcium MAKG" in a dose of 615 g per 1 ton of feed, in the third experimental group "Protical Tri plus" in dose 500 g per 1 ton of feed. It is noted that the use of additives did not adversely affect the coefficients of digestibility of nutrients and use of calcium and phosphorus rations. Introduction in the diets of poultry supplements "Calcium MAKG" and "Protical Tri plus" significantly increased the digestibility of crude fat and nitrogen-free extractives. The introduction of calcium gluconate had a positive effect on digestibility of crude fiber. The results of biochemical blood analysis did
