Pay attention to feeding urea to sheep:
First, strictly control the dosage. Every adult sheep can be supplemented with urea 10 ~ 15g every day, and too much dosage is easy to cause poisoning. 2. Use urea with caution for the first time. Feed urea at the ratio of110 every day, and then gradually increase it to make rumen microorganisms adapt to10 days before feeding the whole amount.
Third, the daily feeding amount should not be 1 time a day, but should be fed in 2 ~ 3 times. Firstly, a certain amount of urea is dissolved in water, and then sprayed on dry materials or mixed with concentrated materials for feeding.
Fourth, after feeding, control drinking water. Don't let the sheep drink water immediately after feeding dry materials containing urea. Drink water after feeding for 30 minutes. Never dissolve urea in water for sheep to drink, which will lead to urea poisoning in sheep.
Five, with sugary feed urea must be fed with a certain sugary feed to have an ideal effect, and can be used with concentrates containing more carbohydrates, such as honey, corn flour, melon dry powder, etc.
Six, adding protein feed urea can not replace all protein feed, while feeding urea, it should also be supplemented with bean cakes, seeds or alfalfa and other feeds containing more protein. It should be noted that bean cake contains urease, which can accelerate the decomposition of urea, so bean cake and urea should not be mixed. If the crude protein content in the diet is higher than 12%, there is no need to add urea.
7. Adding appropriate mineral elements such as sulfur and phosphorus to the diet can improve the utilization rate of urea. Phosphorus can be supplemented with bone meal and sulfur can be supplemented with potassium sulfate or sodium sulfate.
Eight, control the feeding opportunity for sick sheep and weak sheep, it is not appropriate to feed urea; When sheep are excessively hungry, don't feed urea immediately.
Nine, we must continue to use rumen microorganisms to adapt to the utilization of urea, and continuous use can have ideal results. If it is interrupted for some reason, you still need to get used to it when feeding.
X. prevention and treatment of urea poisoning in sheep, when urea poisoning occurs, 10% ~ 25% glucose solution should be injected intravenously quickly, each time 100 ~ 200ml. Giving poisoned sheep 0.5 ~ 1 kg vinegar also has a good first aid effect.
