Winter feed coarse grain and increase efficiency
Roughage generally refers to plant feeds with high crude fiber content and low nutritional value, such as crop straws, leaves, hay, shell awns, glutinous rice pods, and soybean meal. These feeds are coarse in texture, large in size, poor in palatability, and non-digestible, but generally contain more minerals and have a good effect on bone development. The proper processing and preparation of roughage for feeding livestock and poultry, both resistant to hunger and diarrhea, is an effective way to promote the aquaculture industry and increase efficiency.
For short straw grass, as the saying goes: “The three grasses are not used.†Feeding grasshoppers after a short period of time generally saves about 20% of the feed, and the feed utilization rate increases by about 15%. Many feeds are fed The stalks that are eaten by the livestock less or are difficult to feed can be used effectively after a short period of time, and the digestibility is also increased. Generally, the stalks fed to cattle can be split into 4 to 6 cm long segments.
The coarse grass feed is used to mechanically pulverize the crop seed or straw, which facilitates the feeding and digestion of the livestock, and facilitates the mixing of the digestive juice and the grasshopper, thereby reducing the energy consumption in the gastrointestinal digestion process and improving the feed utilization rate.
Hard-grass soft feed is used for forage grass stems and leaves, sub-substances, etc. After salinization, saccharification, ammoniation or microbial fermentation treatment, it can greatly improve its palatability, is conducive to digestion and absorption.
With the coarse and fine forages fed first, the livestock are hungry and can eat more roughage, and then feed the concentrate or high-quality pasture according to their nutritional needs. This will not only save forage but also give full play to the characteristics of ruminants that can use roughage.
The crude vitamin content of rough and coarse feeds is generally low. Feeding livestock and poultry with roughage should be accompanied by appropriate feeding of some green succulent feeds and germinating feeds.
Coarse and coarse with feed for livestock and poultry, should pay attention to the rational adjustment of use, and strive to diversify, do not long-term single feeding a roughage. Otherwise, it will not only fail to meet the nutritional needs of livestock and poultry, but also cause disease. For example, long-term feeding of livestock with wheat straw can cause rumen retardation in cattle and sheep and dyspepsia in horses.
