On October 18th, on-site observation and exchange of straw fermented feed was held at Hebei Agricultural University. The activity aims to transform the traditional feeding methods in the animal husbandry by understanding the straw fermented feed technology, develop and utilize straw to raise livestock, reduce the farming cost of farmers, ease the contradiction between human and livestock food, and promote the establishment of the livestock and poultry farming technology system.
It is understood that the straw fermenting feed probiotics technology was jointly developed by Professor Zhu Baocheng, a farmer and animal microbiology expert of Hebei Agricultural University, and Hebei Zhongbang Biotechnology Co., Ltd. This technology is specially used to ferment crop straw to prepare livestock and poultry feed. After the fermentation of the crop straw by the microbial agent, the nutritional value of the straw roughage can be significantly improved. In addition to being widely used in livestock and poultry breeding, the pollution caused by crop straw burning can also be reduced. At present, this technology has been tested by the Ministry of Agriculture's Feed Potency and Safety Supervision and Testing Center and the China Agricultural Microbial Culture Collection Management Center, and is gradually being put into the market for widespread promotion.
In Hebei Zhongbang Biotechnology Co., Ltd., the reporter saw the fungicide production equipment used in straw fermentation technology—100L seed tank, 2m3 stainless steel fermentation tank, disc-type continuous centrifuge. According to Gao Xiaoming, the person in charge of the company, the company was built after the straw fermented feed technology project was established. It mainly produces the microbial agents used in biological feed, which can meet the demand of more than ten thousand tons of microbial agents every year. These fungicides can be stored for a long time to meet the market requirements for microbial agents.
Li Yutang, director of the Grassland Professional Committee of the China Society of Systems Engineering, senior economist and researcher, gave a high evaluation of straw fermented feed technology. He said that the technology is to ferment crop waste straw and hay leaves into organic feed containing more than 20% protein, which can replace feed grain by about 30%, which greatly saves food, not only alleviates the food crisis, but also reduces it. The cost of animal husbandry has increased the income of farmers. At the same time, this technology is also in line with the sixth industrial revolution proposed by the current society - the biotechnology revolution, which uses industrial, agricultural, and domestic waste to be converted into human use by microbial technology.
Zhu Baocheng, a professor of technology research and development and a professor at Hebei Agricultural University, said that the technology actively responds to the national grain-saving policy, reduces feed grain, and saves production costs and farmers' feed costs. In addition, the technology has played a significant role in promoting the creation of a livestock and poultry farming technology system, protecting the environment, and promoting the development of a new rural circular economy.
In Baigou Town, Yunnan Wugu Sheep and Xiaoqingyang Breeding Base, the reporter could not smell the stench of any animal droppings. “Since the second half of 2010, our base has used this technology. Because it is fermented with straw, it can ensure the stability of feed for a long time, and at the same time improve the environment of the sheep pen, which will greatly promote the healthy growth of sheep. Statistics, sheep can eat this straw fermentation feed can grow 3 pounds of meat per month, according to 25 yuan per pound of lamb to calculate, earning 75 yuan a month. Compared with the previous use of straw fermented feed, the application of this technology makes We have increased our income by 30%-40% per sheep. At the same time, the use of straw for feed has reduced the cost of raising each sheep by 80-100 yuan. This is not an intangible benefit to us." Zhang Qingyun said happily.
