Problems solved by technology

At present, compound enzyme products for pigs, chickens and other corn-soybean meal-based diets have been widely used, but there is no compound enzyme product for the composition and structure characteristics of meat rabbit diets
Due to the major differences in the diet composition of meat rabbits, especially the composition of the diet ratio of meat rabbits in southern my country and the structure of corn-soybean meal-based diets such as pigs and chickens, the application of general-purpose compound enzymes for pigs and chickens in the diet of southern meat rabbits is lacking. sex, the use effect is poor

Abstract

The invention discloses a south type meat rabbit feed composite enzyme additive and applications thereof. The composite enzyme additive is composed of the following components in percentage by weight: 15 to 20% of cellulase, 8 to 12% of xylanase, 4 to 10% of beta-glucanase, 4 to 6% of beta-mannase, 10 to 15% of acidic protease, 1 to 3% of neutral protease, 10 to 14% of alpha-amylase, 2 to 4% of phytase, and 16 to 46% of carrier. The composite enzyme additive can decompose anti-nutritional factors in a south type meat rabbit feed such as coarse fibers, non-starch polysaccharides, phytic acid, and the like, so as to fully degrade nutrients (carbohydrates and proteins) in the feed; and at the same time, the additive can overcome the problem that the secretion of endogenous enzymes of meat rabbits is not enough, can increase the feed digestion and absorption rate of meat rabbits, increases the daily gain, reduces the feed-weight ratio, has high specificity and efficiency, and is capable of effectively improving the digesting performance of meat rabbits on south common type feeds.

Description

technical field [0001] The invention belongs to the technical field of animal feeding and relates to feed additives, in particular to a feed compound enzyme additive for southern meat rabbits and its application. Background technique [0002] According to FAO data, the global rabbit meat output in 2013 was 727,000 tons, accounting for 40.81% of the world's total rabbit meat output of 1.782 million tons. my country has become the world's largest rabbit raising country. Along with the development of the rabbit industry, the rabbit feed industry has also developed rapidly. According to statistics, in 2015, the output of compound feed for rabbits in the whole country was more than 2 million tons. The annual output of meat rabbit compound feed in the producing area also exceeds 1 million tons. [0003] The southern region is the main production area of ​​meat rabbits and the main consumption area of ​​rabbit meat in my country, but as we all know, the southern region of China is...
