Effect of protease supplementation of low protein broiler diets on growth parameters and carcass characteristic

Popis výsledku v původním jazyce

The experiment was conducted to evaluate the effect of addition of exogenous protease into broiler grower diets on growth parameters (body weight and feed conversion ratio) and carcass characteristic (carcass weight and yield). The used exogenous protease was enzyme a mono-component serine protease expressed in Bacillus licheniformis. For the in vivo studies, a heat stable formulated product containing 75,000 PROT/g was used. A total of 990 one-day-old ROSS 308 broiler chickens were randomly divided into 9 experimental units of 110 chickens per each and located randomly to 3 different experimental treatments. The experiment was realized between the 10th and 35th day of age. The basal diet was based on wheat, corn and soybean meal. The dietary treatments were a positive control diet (PC) contained a normal crude protein (CP) level (207 g CP per kg feed, 12.5 MJ/kg) and two low protein diets. The level of CP in the low protein diets (LP) was reduced by 4 % compare to PC. First LP diet (L
