1, supplemented with nitrogen source
The commonly used nitrogen source is urea, which feeds no more than 1% of the dry matter of the sheep diet or 2-3% of the feed of the concentrate. The specific feeding amount of urea depends on the amount of energy feed in the sheep diet. Generally, the energy feed can be fed more often, and less when the energy feed is less. Urea must be fed with digestible concentrate or a small amount of molasses, appropriate amount of sulfur and phosphorus, can not be fed with bean cake and alfalfa, and can not be used to feed sick and starved sheep. Poisoned. When using, the urea should be sprinkled in the moist concentrate to make it dissolve evenly. It is forbidden to dissolve in water or feed alone. Sheep fed the urea diet should not drink water immediately, so it is advisable to drink water after two hours of feeding. If the sheep is poisoned due to improper feeding of urea, a large amount of cold water or an appropriate amount of dilute acetic acid, yoghurt, vinegar, etc. can be administered, and the sheep can be fed with 10% acetic acid plus glucose mixture 1.5-2 liters.
2, the use of rumen technology
Feeding rumen protein and ruminal starch can increase the feed intake of sheep and promote the absorption of amino acids in the small intestine, thereby increasing hair production and milk production.
3, plus fermentation energy
Grain feeds such as barley, wheat, oats, corn, and sorghum, which contain more starch, can increase the fermentation energy of the diet and increase the utilization rate of the roughage of the sheep.
4, supplemented silage
Supplementing a small amount of silage corn during the dry grass stage can promote the growth of rumen microorganisms in sheep and improve the utilization of roughage.
5, supplemented with minerals
The mineral elements that may be lacking in sheep, such as calcium, phosphorus, sodium, potassium, selenium and copper, can be supplemented by mixed feeding or salt bricks, mineral pills and sustained release devices.
