Biotechnology makes straw into livestock nutrient feed
Through biotechnology "turning waste into treasure", using ordinary crop straws and alcohol waste liquid as raw materials to produce nutrient-rich high-protein new animal feed, recently this new high-protein biological straw feed was successfully developed in Harbin and put into mass production. This brand-new bio-agricultural high-tech product is of great significance for providing more safe, efficient, and cheap feed, effectively solving the competition for feed cultivation, realizing grassland recuperation, and developing an environmentally friendly circular economy.
In recent years, by investing in a new technology of microbial fermentation, high-protein bio-straw feed was produced using crop straw and alcohol waste liquid as raw materials. In 2010, the first phase of its holding Harbin China Brewery Co., Ltd. was completed with a scale of 100,000 tons Construction of high protein biological straw feed production line.
According to reports, the technology uses various types of crop straws as raw materials, through fine processing, to produce high-quality high-protein forage feed with high nutrition, good digestibility, and strong palatability. It uses the soluble protein in corn alcohol waste liquid and crop straw to inoculate microorganisms for solid aerobic and anaerobic continuous fermentation to produce high-protein biological straw feed, and realizes the recycling of industrial wastewater. After analysis and testing by the Heilongjiang Quality Supervision and Inspection Institute and the Ruminant Nutrition Laboratory of Northeast Agricultural University, the technical parameters and design of the new feed safety, fermentation quality, nutritional value, biological potency and feeding effect observation The indicators are basically consistent, achieving the expected nutritional value and feeding effect. After feeding trials on dairy cows, it is proved that not only the milk production is increased, but the quality of milk is also greatly improved. After the calculation, the price of high-protein bio-straw feed is far lower than the price of whole-plant corn silage and Leymus chinensis.
Experts believe that the production of high-protein bio-straw feed expands the source of high-quality forage feed and silage and opens up China's second grassland resources.
