The Influence of the Different Levels of Crude Proteins in Feed Mixture for Pigs and Poultry and Biopolym Adition to Concentrate for Farm Building Microclimate

Abstract

Reducing level of protein at the concentrates for pigs and poultry allowed to solve duality o fair conditions at the farme buildings. By the fattening pigs increased on 0.032 kg daily gain weight and decreased on 0.45 kg feed consumption respectively. The addition of 400 g of Biopolym increased pigs daily gain and feed consumption was reduced. At the broiler chickens by the 2.92 % les of protein decreased a mortality of chickens about 1.8% in experiment group. The others results were the same as in control group of chickens. The levels of ammonia and hydrogen sulfide were lover than maximum data from Czech norms (NH 3 max. 25 ppm and H2S max. 7-10 ppm) at experiment and control groups.
