Effects Of Compound Enzyme GSM Preparations Supplemented To Different Meals On Broilers

This experiment was conducted to investigate the effects of diets GSM complex enzymes on growth performance, terminal ileum nutrient digestibility and ileum chyme relative viscosity of AA white broilers fed wheat-based diets and corn-based diets. It was selected and the growth of normal, healthy 1-day-old AA broilers 1296, were randomly divided into 12 groups, each with nine replicates of 12 chickens, male and female in half, each repeating a significant difference chick initial body weight without (P> 0.05). In the 1-12 group,1-6 group test chickens fed corn-soybean meal diet, the first group of test chickens fed wheat 7-12-soybean meal diet, while the diet group were 1-6 as follows: Group 1 was normal energy level basal diet (feeding two stages, dietary metabolizable energy were 12.35MJ/kg and 12.77MJ/kg); the second group and the third group were fed on the basis of group Save on food 0.314 MJ/kg and 0.628 MJ/kg metabolic energy of low-energy diets; Group 4,5 and 6 in the third group on the basis were added 300 g/t · GSM,600g/t · GSM,300g/t· GSM+500g/t· emulsifier.7-12 diet group were:7 normal energy level group basal diet group (two-phase diet metabolizable energy were:12.35MJ/kg and 12.77MJ/kg); Group 8 and Group 9 They were set on the basis of the diet minus 0.314 MJ/kg and 0.628 MJ/kg metabolic energy of low-energy diets; and 12 groups of 10,11 is added 300 g, respectively on the basis of Group 9/t · GSM, 600 g/t· GSM,300g/t· GSM+500g/t· emulsifier, the whole test period of 42 d. Tests 22 d and 43 d to repeat as a unit, weighing fasting, said remaining material weight, body weight gain calculation stage (BWG), feed intake (FI) and feed conversion ratio F/G; when test 44 d,3,4,6,9,10 and 12 in each group were randomly selected five chickens, bled to death after epilation neck cut open, remove the gut, ligation ileum digesta taken part chyme and frozen at -20℃ with the determination of ileal digestibility of nutrients and energy efficiency, part of ileal digesta for measuring the relative viscosity.. The results showed that, (1) Addstion GSM complex enzyme to the corn-based diets has no obvious effect on the growth of broilers (P> 0.05); while added 600g/t · GSM to wheat-based diets can certainly improve the broilers production performance (P>0.05) compared with the 9th group (deceased 0.628 MJ/kg diet) body weight increased by 2.1%, feed intake lowered by 2.4%, material weight ratio decreased by 4.9%. (2) Added GSM to the corn-based diets has no significant influence on broilers terminal ileum nutrient digestibility(P> 0.05); Added to the wheat-soybean meal type diet broilers terminal ileum nutrient digestibility has varying degrees of improvement, in which add of 300 g/t · GSM+500g/t·emulsifier can obviously increase the terminal ileum digestibility of protein and phosphorus (P< 0.05). (3) Added GSM in the corn-based diets has no significant effect on broilers ileum chyme relative viscosity (P> 0.05); Added GSM to the wheat-based diets can lower the ileum chyme relative viscosity approximate 8%(P< 0.05).(4) The economic analysis by adding 600g/t· GSM produce best.The comprehensive results show that the GSM is added in the wheat-soybean meal type fodder can significantly reduce the ileum chyme relative viscosity, improving some nutrient digestibility, thus improve the poultry production performance, and in the corn-the effect is not significant in soybean meal type fodder; Wheat-soybean meal fodder to reduce 0.628 MJ/kg fodder metabolism can also add 600 g/t. GSM can achieve normal metabolism can fairly set of production performance and the GSM and the effect of emulsifying agent combined effect is superior to the single use of GSM and economic analysis by adding 600g/t· GSM produce best.
