Title: Effects of Enzyme Additives in Wheat-and Double Low Rapeseed Meal-based Diets on Performance of Growing-finishing Pigs
Abstract: A total of 65 crossbred piglets(Duroc Large White Landrace) weighing 22.5 kg were allotted,based on weight and sex,to five dietary treatments with 13 replicate pens each and 1 pig per pen as a replicate.The five dietary treatments were diet 1 based on corn and soybean meal(control),diets 2 and 3 based on double low rapeseed meal and supplemented with enzyme A and B,at 0.01% of diet,and diets 4 and 5 based on wheat and supplemented with enzyme A and B,at 0.01% of diet.The experiment were conducted in two phases(phase 1: 22.5~70 kg;phase 2: 70~90 kg) for 80 days.During any phase,double low rapeseed meal-based diets with enzymes A or B additives had a growth rate and feed efficiency similar(P0.05) to the control.However,compared to the control,double low rapeseed meal-based diets with either enzyme A or B additives decreased cost per kg of gain by 0.51 and 0.47 yuan,and 0.69 and 0.81 yuan,respectively,during phase 1 and phase 2.During phase 1,wheat-based diet with enzyme supplementation significantly improved growth rate(P0.05) and feed efficiency((P)0.01) than the control,and also reduced cost per kg of gain by 0.52 and 0.53 yuan,respectively,compared to the control.During overall phase,wheat-based diet with enzyme A supplementation improved significantly feed efficiency(P0.01) than the control.The results indicated that both enzymeshad positive effect on growth performance of pigs fed on double low rapeseed meal-and wheat-based diet.Wheat-based diet's effect was more obvious.
