Straw is characterized by high crude fiber content (30%-40%) and contains lignin. Although lignin cannot be used by pigs and chickens, it can be absorbed and utilized by ruminants such as cattle and sheep. Since straw is a poor quality rough feed, when it is used as a feed, it is necessary to pay attention to adding a proper amount of supplemental nutrients in order to increase its use value, increase the output of livestock and achieve reasonable use. The specific approach is: First, the metabolic energy of energy-supplemented straw feeds is generally no more than 8-37 MJ/kg (for ruminants), and the net energy is relatively lower. Therefore, only the general growth and development needs of livestock can be maintained. If you need to produce milk and gain weight, you must supplement fine material (treasure molasses or quality hay, etc.). According to the survey, the amount of general supplements should be between 20% and 60%. 2. The crude protein content of supplemental nitrogen crop straw is generally between 3% and 4%, so it can only maintain the usual growth and development requirements. Ruminants such as cattle and sheep can utilize non-protein nitrogen as a nitrogen supplement by rumen microbes. However, when using protein nitrogen as a nitrogen supplement, it is best to heat and formaldehyde, and then mix with forage grass for feeding. Third, supplement minerals and vitamins. Straw phosphorus content is generally 0.02% -0.16%, while the normal growth and reproduction of livestock requires about 0.3%. Therefore, if straw is used as the main feed to feed livestock, phosphorus, calcium and other trace elements such as zinc and selenium are needed. Vitamin supplementation is generally most important with vitamin A or carotene. This can be solved by feeding green feed or synthetic vitamin A.
