This study organized two tests, using spraying liquid non-starch polysaccharide enzyme onto the particle feed decreased energy, and determining the growing performance of 21-42 day-old broilers and metabolic test of 21-35 day-old broilers, to assess the liquid NSP enzyme effects of particle feed, and provide a scientific basis for the application of non-starch polysaccharide enzyme and wheat.In Exp1, a randomized trial by the single factor was designed, selected 2400 healthy 22-42 day-old Ross broilers were randomly divided into four treatment groups. Each treatment group had 6 replicates of 100 birds. Positive control group used base diet, and the negative control group used the diet decreased 100 ME/kg. Group 1 is the negative control group based on dietary added 200ml/T liquid non-starch polysaccharide enzyme; the dietary decreased 150 Kcal/kg of the group two was added 200ml/T liquid non-starch polysaccharide enzyme. By determining the growing performance of two treatment, the results showed that there was an increased weight gain by 17%(P<0.05),7.7%(P<0.05)and 12.8%(P<0.05). Daily weight gain of the group 1 was higher than the negative control group and the group two by 10.4% (P<0.05) and 6%(P<0.05); FCR of the group one was lower than the negative group by 0.19, and the group two by 0.20, but the difference was no significant. Experiment 1 compared with the control group, the average full costs was lower 331 yuan per ton of feed; Increased the economic efficiency by 3.3%.In Exp 2, Selecting 288 similar 21-day weight, body condition and healthy meat cock Ross, were randomly divided into four treatment groups, each treatment group had 12 replicates of 6 chickens fed separately, Positive control group used base diet, and the negative control group used the diet decreased 100 ME/kg. Group 1 is the negative control group based on dietary added 200ml/T liquid non-starch polysaccharide enzyme; the dietary decreased 150 Kcal/kg of the group two was added 200ml/T liquid non-starch polysaccharide enzyme. The results showed:contrasted with negative control group, the food intake of expl was increased by 0.88%, daily weight gain increased by 0.85%, and an significant increased of AME of dietary by 50kcal/kg (P<0.05), and energy efficiency increased by 1.08 (P<0.05), viscosity of lleal decreased by 19.43%(P<0.05)The conclusions of this test:the wheat diet of broilers using liquid non-starch polysaccharide enzyme, Viscosity of Heal of broilers was decreased obviously, food intake and weight gain increased and FCR decreased, AME of dietary increased. Feed prices at the time, it increases the economic benefits of broilers。... |
