Effects of Compound Enzymes on the Performance and profit of Growing Pigs Fed Low Protein and Low Soybean Meal Diets
The aim of this experiment is to investigate the effects of low protein and low soybean meal diets on the production performance and economic benefits of growing pigs.360 healthy Duroc growing pigs weighing around 36 kilograms were selected for the experiment and randomly divided into 4 groups,with 6 replicates in each group and 15 pigs in each replicate.Control group A was fed normal diet with high soybean meal(CP 17.0%).Group B was fed low protein diet with high soybean meal(CP 15.0%).Group C was fed low protein diet with low soybean meal(CP 15.0%),and group D was fed low protein diet adding compound enzymes with low soybean meal(CP 15.0%).The experimental period was 30 days.The experimental results indicate that:A low protein and low soybean meal diet had no significant effect on the average daily weight gain,average daily feed intake,and feed to weight ratio of growing pigs(P>0.05).The cost of weight gain per kilogram of body weight is best in the group D with low protein and low soybean meal and compound enzymes,which is 0.49 yuan/kg lower than the normal diet control group A.
