Technical Field

The invention belongs to the field of livestock breeding feed, and particularly relates to a high-protein high-fiber pig feed and an application and a preparation method thereof.

Background

The livestock industry in China develops rapidly, the livestock and poultry stock keeping quantity and the annual output of livestock and poultry products are increased year by year, and therefore the demand quantity of the feed is also increased year by year. The total yield of the feed in China is increased from 1.37 hundred million tons in 2008 to 1.94 hundred million tons in 2012, and is increased by 41.6%. Compared with the prior art, the grain yield increase range in China is relatively low, and only 11.5% of the grain yield increase is realized between 2008 and 2012. However, with the development of economy and the advancement of urbanization in China, the cultivated land area in China is decreasing year by year. The cultivated land area of China in 2012 is 18.26 hundred million mu, which is close to the cultivated land red line (18 hundred million mu) specified by the country in 2007. In a word, the problem of shortage of feed raw materials in China always influences the development of animal husbandry in China, and becomes a great challenge for the future development of animal husbandry in China. Therefore, on the basis of guaranteeing the food safety, the search for new feed raw materials or unconventional feed raw materials to save bulk raw materials such as corn, bean pulp and the like is a research hotspot of the feed industry and animal husbandry at present.

Coconut trees are widely distributed in tropical regions, with main producing areas being indonesia, philippines, india and some south american countries. Worldwide coconut flour and coconut meal yields are about 2 million t (Soyatech, 2012). Coconut meal is a by-product produced by pressing or extracting pressed oil from desiccated coconut kernels. Coconut meal typically has a protein level of 20% -26% which can always be significantly higher than corn. The coconut pulp has high fiber content, low effective energy value and high arginine content (about 1.9-2.3%), and lacks lysine, methionine and histidine, and contains fat which belongs to saturated fatty acid and high vitamin B group. The bean dregs are the by-products in the process of producing bean products such as soymilk, bean curd or dried bean milk rolls, and the like, and because the consumption of bean products in China is large, the yield of the bean dregs is correspondingly large. The bean dregs have rich nutritive value, and the air-dried sample contains 18-23% of crude protein and 50-55% of total dietary fiber. Particularly, the bean dregs contain rich lysine, and the situation that the content of other raw materials in the feed is insufficient can be compensated by using the bean dregs as the raw materials to prepare the feed. The coconut pulp and the bean dregs have the characteristics of large yield and low price, and the feed prepared from the coconut pulp and the bean dregs can effectively relieve the problem of lack of feed raw material resources and effectively reduce the breeding cost.
