Straw into the belly (dynamic)

Introduction: yesterday, the reporter learned from Chengdu Municipal Bureau of agriculture and animal husbandry that the "agricultural straw series animal protein feed project" which has obtained the national patent and has been successfully tested is about to be put into operation and blossom Recently, a Taiwanese enterprise has signed an agreement to invest 80 million yuan in the production of straw feed It is reported that the project will be popularized and applied in Qingbaijiang District first, and will "digest" all straws in the whole district by next year, and then be popularized in Chengdu and Sichuan Province Adding bacteria straw to feed In Chengdu Hongyu high tech protein factory in Qingbaijiang District, the reporter saw this magic production process: the workers first broke the straw they received, put it into the reaction tank for humidification, heating and degradation, and then added a kind of magic biological bacteria to generate monosaccharide polysaccharide When it was mixed and fermented with bean cake, high-quality protein feed was generated The whole production process was It's automated, very simple According to experts from the Municipal Bureau of agriculture and animal husbandry, straw includes straw, wheat straw, corn cob, etc., which is mainly composed of crude fiber It is a by-product of the main agricultural and economic crops in Chengdu Plain It is useless for farmers to bring it, and they often burn it, causing "smoke" in the air over the city In recent years, the government has spent a lot of manpower and material resources to "prohibit burning", but there is no good way out, so it is still repeated It's not just forbidden Since 2001, Li Yongcheng, a professor in the school of biology of Sichuan University, has been cultivating a strain of bacteria, which uses the effect of biological enzymes to transform the fiber components in straw into protein that can be absorbed by animals It is reported that this technology has been studied for hundreds of years abroad, but it is still the first in China, so it also obtained the national invention patent in 2003 The cows fed with straw feed are 0.2m high Due to missing the beef cattle feeding season, the reporter did not see the beef cattle used for the experiment in the base, but through the short film, the reporter saw a group of data: because the protein content of the new feed is rich, so compared with the cattle fed with the common feed, the cattle fed with the new feed at the same time have a significantly larger body size, and the average height of each head is 0.2m by measurement! "This kind of feed is not only effective, but also cheap," the owner of a farm who bought it from Guangyuan told reporters It is understood that the traditional feed needs to use 20% of grain, and the price per ton is about 2000 yuan, while the price of straw feed raw materials is low, which can be 500-800 yuan cheaper per ton Therefore, during the experiment period, the new feed of Hongyu protein factory was in short supply Not only the nearby farmers like to use it, but also the farmers of Guangyuan and Wangcang came here It is understood that Chengdu needs nearly 4 million tons of feed every year If we use straw feed instead, we can not only save 800000 tons of grain per year, but also save 2 billion yuan of cost Due to the double benefits of economy and environment, the project has attracted great attention of Chengdu agriculture and science and technology department It is reported that by June 2005, a straw feed factory with an annual output of 10000 tons will be built in Qingbaijiang District, 40 large breeding households and corresponding technicians will be cultivated, and 50000 tons of straw will be used to produce 150000 tons of feed By the end of 2005 Chengdu has completed the layout of 900000 tons of straw production plant annually; by 2006, the whole city and some parts of Sichuan Province will basically popularize straw feed production technology, and soon, the problem of straw burning prohibition will be completely solved Reporter Wang Fengru and Liu Zhi travel around
