To improve grassland ecological environment, in the final analysis, it is necessary to solve the feed problem of cattle and sheep in the livestock husbandry of the grasslands, and to diversify the feed of cattle and sheep. The straw pellet meal developed by Daqing Jinshi Feed Co., Ltd. of Heilongjiang Province has solved this problem. The straw pellet feed is a new breed of cattle and sheep roughage developed on the basis of an in-depth investigation of the roughage of animals such as cows and goats in China, which fills a gap in the roughage of cattle and sheep in China and enables livestock husbandry in the grasslands to Simply relying on grassland forage changes to rely on feeding, thereby reducing the pressure on the grasslands. Straw granules obtained a number of national invention patents, they are: soybean straw granules, straw granules, corn stalk granules, and glutenous granules. Straw pellets and feeds have the following advantages: Straw granules are used for roughage, and the industrial production of cattle and sheep roughage is achieved. It has changed thousands of years of storage in open storage for storage. It produces 70°C temperature and heavy extrusion in production to prevent pests and diseases. Invasion of people, there is no emission of three wastes in production, and the moisture content of particulate plutonium is controlled at about 13%. It can be used in a variety of geographical environments and stored for a long period of time. The straw grain plutonium meets the characteristics of cattle and sheep roughage and is therefore known as cattle. Sheep's compressed biscuits. Reduced transportation costs. Straw pellets are 1/3 of the bale volume, and rail and water transport can reduce freight by 2/3 compared to straw bales. Ammoxidation and silage can only be sourced in the farming area, used on the spot, and cannot be transported over long distances. The bulk of the bales has a large freight rate, while the largest advantage of the pellets is low freight. In northern China's vast pastoral areas, snowstorms of varying degrees occur every winter and are referred to as white disasters by a large number of farmers and herdsmen. The characteristics of grain-grass feed itself are very favorable for fighting against disaster feed supplies and can be used as a commando for self-rescue against disasters. ". At present, particles and feedstuffs have been serialized and multi-variety varieties are available for users to choose. China has a vast land area, but the distribution of arable land is very uneven. The per capita arable land area is only 1.51 mu. The main grain-producing areas in each province are relatively concentrated and have different straw particles. The feed was developed for different varieties of grain in the major grain-producing areas. Its purpose is to form a vast area of ​​strawgrass feed near the provinces of the northern savannah of our country. The pellets are fed to the grasslands and lack grass feed. The region provides a large amount of roughage to meet the needs of animal husbandry development. China produces a total of 575.2 million tons of straw each year. If the use of 10% of the production of pellets and feeds amounts to 57.52 million tons, while other varieties of straw feed are selectively used, and the production process of pelleted feed is different, it can produce a variety of straw pellets and feed, that is, both hard and soft straw. Can be fully utilized, and achieve good palatability, cattle, sheep like the purpose.
