Embodiment 1

[0067] Effects of Compound Enzyme Preparations for Improving Breeding Performance of Broiler Chickens on Production Performance of Broilers

[0068] In this case, 320 1-day-old AA broilers were randomly divided into 4 treatment groups, each treatment had 4 replicates, and each replicate had 20 broilers. Treatment 1 is a positive control group; treatment 2 is a negative control group, fed with an energy diet that is 80 kcal / kg lower than the control group; treatment 3 is a negative control group + a compound enzyme preparation that improves broiler feeding performance; treatment 4 is a negative control group Control group + imported enzyme. The specific addition levels are shown in Table 1. The experiment was divided into two feeding stages: 1-21d and 22-42d. The feeding management is carried out according to the routine procedures of commercial chicken farms, the chicken house is kept clean and dry, and the mental status, activity status, feeding and diarrhea diseases of the...

[0098] Effects of compound enzyme preparation for improving broiler feeding performance on serum biochemical indexes and nutrient metabolism rate of broiler chickens

[0099] The experimental design and basal diet formula of this case are the same as case 1.

[0100] A total of 320 1-day-old AA broilers were selected and randomly divided into 4 treatment groups, with 4 replicates for each treatment and 20 broilers for each replicate. Processing 1 is a positive control group; Processing 2 is a negative control group, feeding an energy diet that reduces 80kcal / kg compared with the control group; Processing 3 is a negative control group+the compound enzyme preparation that improves broiler breeding performance of the present invention; processing 4 is the negative control group + imported enzyme. The specific addition levels are shown in Table 1. The experiment was divided into two feeding stages: 1-21d and 22-42d. The feeding management is carried out according to the routine...

Abstract

The invention discloses a complex enzyme preparation improving broiler chicken breeding performance. The complex enzyme preparation is characterized by being prepared from a carrier, xylanase, cellulase, alpha-galactosidase, beta-mannase, pectinase, amylase, lipase and protease, wherein xylanase, cellulase, alpha-galactosidase, beta-mannase, pectinase, amylase, lipase and protease are added in the carrier. In each gram of the complex enzyme preparation improving broiler chicken breeding performance, the activity of xylanase is 1000-10000 U, the activity of alpha-galactosidase is 2-40 U, the activity of cellulase is 100-3000 U, the activity of beta-mannase is 100-2500 U, the activity of pectinase is 100-3000 U, the activity of amylase is 100-3000 U, the activity of lipase is 50-2000 U, and the activity of protease is 1000-10000 U. According to application of the complex enzyme preparation improving broiler chicken breeding performance in broiler chicken feed, 100-1000 g of the complex enzyme preparation is added in each ton of complete feed. The complex enzyme preparation can generate the emergy of 25-85 kcal / kg, effectively degrade antinutritional factors such as soluble xylan, mannan and alpha-galactoside, increase the digestion rate of nutrients such as protein and amino acid, improve broiler chicken productivity and lower breeding cost.

Description

technical field [0001] The invention relates to a composite enzyme for improving the breeding performance of broilers and its application. Background technique [0002] The addition of 50% to 70% of corn in the corn-soybean meal-based diet provides 60% to 70% of the energy source of the formula, and its cost accounts for more than 60% of the total cost. The traditional view is that the digestibility of cornstarch is very high, often reaching more than 90%. However, studies in recent years have found that the digestibility of cornstarch is not as high as people thought. Milan et al. conducted research on chickens of different ages: from 3 days to 21 days, the starch digestibility of the terminal ileum did not exceed 85%, and it did not increase significantly with age. Studies by Antione and others have shown that the starch digestibility in the ileum of 35-day-old broiler chickens can be as low as 80%, and there are large differences among corn specimens. Microscopic observ...
