Embodiment 1
[0020] According to xylanase 10%, cellulase 10%, β-mannanase 8%, α-galactosidase 15%, acid protease 10%, medium temperature amylase 10%, glucoamylase 10%, carrier 27 The ratio of % is uniformly combined to obtain a special compound enzyme feed additive of corn soybean meal type, and its main component analysis guarantee value is: xylanase 6000U / g; cellulase 700U / g; β-mannanase 2500U / g; α-galactosidase 300U / g; acid protease 10000U / g; medium temperature amylase 600U / g; glucoamylase 20000U / g.
[0021] Add the additive at 0.2‰ of the weight of the full-price compound feed.
[0022] The experiment adopts a single factor completely random design, selects 750 AA broilers of similar origin, age and body weight, and randomly divides them into 3 treatments, each treatment has 5 repetitions, and each repetition has 50 chickens. Positive control group, negative control group and test group were respectively set up, fed with corn-soybean meal-based ration, corn-soybean meal-based ration w...
Embodiment 2
[0028] Xylanase 12%, Cellulase 15%, β-Mannanase 5%, α-Galactosidase 5%, Acid Protease 5%, Moderate Amylase 10%, Glucoamylase 5%, Carrier 43% Combining uniform proportions, a special compound enzyme feed additive of corn soybean meal type is obtained, and its main component analysis guarantee values are: xylanase 7200U / g; cellulase 1000U / g; β-mannanase 2000U / g; α -Galactosidase 100U / g; acid protease 7500U / g; medium temperature amylase 600U / g; glucoamylase 10000U / g.
[0029] Add the additive at 0.5‰ of the weight of the full-price compound feed.
[0030] The formula in this example is more suitable for pigs, and the effect is very good.
[0031] The piglet experiment was carried out with the special compound enzyme feed additive of corn and soybean meal. The present embodiment is divided into a control group and a test group, and selects 48 piglets with an average body weight of 9.08 kg and is divided into two groups, each group is divided into three repetitions (columns), a...
