Sheep winter and spring feeding method
Sheep winter and spring supplement method In winter and spring season, there is less material in the grass and the supply of crude protein and other nutrients is seriously insufficient. At this time, the temperature is low and the energy consumption of the carcass is large. The ewes are pregnant, breast-feeding, long-haired, and long-haired. The demand for nutrients has increased, and grazing alone is far from meeting its nutritional needs and must be supplemented by supplementary feeding. For the main nutrient-limiting factors for grazing, the following methods can be used for supplementation. The common source of nitrogen for supplemental nitrogen sources is urea, which does not exceed 1% of the dry matter of the sheep's diet or 2% to 3% of its concentrate feed. The specific feeding amount of urea depends on the amount of energy feed in the sheep's diet. Generally, the energy feed can be fed for a long time, and the feed for energy can be fed less when the energy feed is low. Urea must be fed with digestible concentrate or a small amount of molasses, moderate amounts of sulphur and phosphorus, and fed in small amounts one after another. It cannot be fed with bean cakes or quail, nor can it be used to feed sheep that are in conditions of disease and starvation. Poisoning. When using, urea should be sprinkled in the wet concentrate to make it evenly dissolved. It is forbidden to be dissolved in water or fed separately. Sheep fed a urea diet cannot drink water immediately, and it is advisable to drink water after stopping feeding for two hours. If urea is fed improperly to cause sheep poisoning, a large amount of cold water or a proper amount of dilute acetic acid, yogurt, vinegar, etc. can be fed, and the sheep can be fed with 10% acetic acid plus glucose mixture 1.5 to 2 liters under certain conditions. Rumen-supplemented rumen protein and ruminal starch supplementation can increase sheep feed intake, promote amino acid absorption in the small intestine, and increase wool production and milk production. Increasing the amount of starch-rich feeds such as barley, wheat, oats, corn, and sorghum that can be supplemented with fermentation can increase the fermentation energy of the diet and increase the sheep's utilization of roughage. Compensatory silage supplemented with a small amount of silage corn in the withered period can promote the growth of rumen microbes in sheep, and improve its utilization of roughage. Mineral supplements Calcium, phosphorus, sodium, potassium, selenium, and copper, which may be lacking in minerals, may be supplemented by mixed feeding or salted bricks, mineral pellets, or sustained-release devices.
