BEIJING, Dec. 25 (Xinhua) — In Longzhou County of south China’s Guangxi Zhuang Autonomous Location, farmers are hectic harvesting sugarcane in the fields. Sugarcane leaves, which used to be squander, will be processed and created into cattle feed at nearby feed factories.

“In the previous, sugarcane leaves and corn stalks had been possibly dumped or burned. Now it can be utilized as feed. Past calendar year, I earned 26,000 yuan (about 3,728 U.S. bucks) from providing stalks,” stated Ruan Zhenhong, a regional farmer.

A new mode of industrial utilization of rice straw has also been produced lately in the metropolis of Changde in central China’s Hunan Province, as folks have recycled rice straw and processed it into silage.

“Rice straw simply cannot be burned. The rotted kinds remaining in the fields are an ‘ecological stress.’ They may possibly have an effect on the subsequent cultivation and guide to plant disorders and insect pests,” explained Luo Yuanfeng, an official with the bureau of agriculture and rural affairs of Changde.

China’s feed market is witnessing fast improvement, transformation and upgrading. Endorsing biological feed technology is an inevitable route and strategic evaluate to guarantee the superior-excellent growth of China’s feed business, explained Xin Guochang, an official with the Ministry of Agriculture and Rural Affairs.

Organic feed is the standard expression for a new feed useful resource and feed additive, which is protected, productive, environmentally welcoming and residue-free of charge, and made by indicates of contemporary biotechnology these kinds of as genetic engineering, protein engineering, enzyme engineering and fermentation engineering, in accordance to a examine report on China’s organic feed market.

Organic feed enjoys a vast selection of resources. It is renewable and fewer costly than distinctive feed. The software of organic feed is valuable to producing unconventional feed methods and decreasing breeding expenditures. It is also conducive to preserving foodstuff and easing the trouble of persons and animals competing for food, the report stated.

The organic feed can also lower the discharge of nitrogen and phosphorus in livestock and poultry manures, drastically minimizing environmental pollution and promoting the healthful and sustainable advancement of the animal husbandry feed sector.

In current yrs, biological fermentation technology has accomplished excellent results in improving feed quality and feed utilization efficiency, and endorsing animal well being. Ecological pig feeding is a great illustration.

“Bio-fermented feed is a form of bioactive feed containing probiotics and their metabolites. Microbial fermentation can improve the digestibility fee of feed by altering the physicochemical houses of feed substrate,” mentioned Wang Yizhen, a professor at Zhejiang College.

He extra that the bio-fermented feed can also improve pigs’ intestinal operate and system immunity by way of the result of probiotics, serving to ensure pig wellbeing and superior-quality generation.

China attaches fantastic relevance to the advancement of the organic feed sector. At existing, there are much more than 1,000 enterprises engaged in bio-fermented feed creation in the place.

Chian has taken productive actions from the views of the administration procedure and complex specifications to boost the standardization of the business.

“The institution of guidelines and criteria has built significant contributions to the immediate development of China’s biological feed field, with an once-a-year output exceeding 4 million tonnes,” Wang reported.
