Chicken manure became the raw material of pig food

Introduction: working as "Hongniang" by the Municipal Office of production, education and research, relevant people from Changshu Municipal Bureau of township enterprises came to Shanghai Fisheries University today They are very interested in the invention of the University's experts to turn chicken manure into pig, mutton and fish rations It seems that the industrialization of the research results of chicken manure puffed feed has a door! Yin Zhaojun, a professor at the University of fisheries, said that because chickens have no chewing organs and have a short digestive tract, it's a pity that after eating, the nutrients in the food are not fully absorbed and then excreted out of the body According to the determination, 80% of chicken manure is undigested feed, with the content of crude protein ranging from 25% to 30% The content of crude protein in chicken manure is more than that in basic feed when chicken is eating, which mainly increases the role of microorganisms in intestinal biosynthesis Experts use the expansion processing method to process it into a new feed, which can be used for pig, mutton and fish First of all, chicken manure can contribute to solving urban environmental pollution According to the data, at present, there are more than 1600 large and medium-sized livestock farms in Shanghai, with an annual output of more than 7.4 million tons of feces and urine, of which chicken manure accounts for a large proportion The water quality of many rivers is obviously polluted However, due to the high cost of investment in the construction of pollution control facilities, many farms are unable to bear it If it can form a biological chain, it is no better to solve the problem of livestock manure Secondly, it can alleviate the problem of feed China's total feed output has increased from about 5 million tons at the beginning of 1980s to about 65 million tons at the end of the century However, with the increasing population and the reduction of arable land, the conventional feed resources for feed industry are becoming more and more scarce, and the contradiction between livestock and human is becoming increasingly prominent The development of chicken manure feed has greatly enriched the feed resources (author:) share to feed Weibo share to:
