Embodiment 1

[0012] With 10000IU / g cellulase and 30000IU / g xylanase and 10000IU / g glucanase and 2000IU / g amylase and 50000IU / g protease and 5000IU / g phytase and starch according to weight ratio 1.7: 0.06: 0.35: 0.02: 0.25: 0.15: 1 combination, the compound is evenly mixed to obtain a special compound enzyme feed additive for rice.

[0013] Add this additive by 0.05% of the weight of the complete compound feed.

[0014] The formula in this example is more suitable for poultry, and the trial effect is very good.

[0015] The meat duck experiment was carried out with the special compound enzyme feed additive for rice. 270 21-day-old Cherry Valley meat ducks with a body weight of 1130.83±2.07g were selected and randomly divided into 3 groups according to the principle of consistent body weight, with 3 repetitions (circles) in each group and 30 ducks in each group. They were divided into positive control group, negative control group and test group, and were fed with corn-soybean meal ration,...

Embodiment 2

[0027] With 10000IU / g cellulase and 30000IU / g xylanase and 10000IU / g glucanase and 2000IU / g amylase and 50000IU / g protease and 5000IU / g phytase and starch according to weight ratio 0.2: 0.12: 0.45 : 0.04 : 0.1 : 0.8 : 1 combination, the compound is evenly mixed to obtain a special compound enzyme feed additive for rice.

[0028] Add this additive by 0.01% of the weight of the complete compound feed.

[0029] The formula in this example is more suitable for pigs, and the trial effect is very good.

[0030] The piglet experiment was carried out with the special compound enzyme feed additive for rice. 48 piglets weighing 26.66±0.96kg were divided into two groups, each group had three replicates (pens), and each pen had 8 piglets. The origin, age and body weight of the piglets are similar, and the sexes are the same. Divided into control group and test group, they were fed with corn-soybean meal type diet, 40% rice-corn-soybean meal type diet+100g / t special enzyme preparation f...

Abstract

The present invention discloses a complex enzyme feed additive for rice only, which is mixed and made by cellulase, xylanase, glucanase, amylase, protease, and the compound of phytase and the carrier according to a certain proportion. The present invention has the highlight advantages that the feed additive contains a variety of non-starch polysaccharides enzyme, and contains protease and amylase, which can effectively reduce the anti-nutritional factors in the rice, and promote animal digestion; compared to the similar compound enzyme additives, which has the advantages of high efficiency, specificity and less quantity adding. Using the feed additive can promote animal growth and improve feed conversion efficiency.

Description

technical field [0001] The invention belongs to the technical field of animal husbandry or feed, and relates to a feed additive, in particular to a special compound enzyme feed additive for rice. Specifically, the invention relates to a rice-specific composite enzyme feed additive that can help livestock and poultry improve the digestibility of rice-type feed and reduce the feed-to-meat ratio. Background technique [0002] Scientific practice shows that rice can completely replace corn feed to feed pigs and chickens. As the prior art, the traditional feeding method of rice is directly crushed as feed, because rice contains fiber and a large amount of anti-nutritional factors that cannot be utilized by pigs and chickens as monogastric animals - xylan, β-glucan, etc. Its utilization value is much lower than that of corn, which severely limits the amount of rice used in feed. In order to increase the utilization value of rice, it is necessary to increase the energy utilizatio...
