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
Keywords:
Biopolym, farm building microclimate, pig, poultry, true proteinAbstract
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.
