Can lambs be fed with urea added silage, and why should sheep be fed urea?

It can be fed gradually and appropriately, and it is better not to feed it, it is too dangerous.

1. Strictly control the dosage: each adult sheep can supplement 10 15 grams of urea per day, and too much dosage is easy to cause poisoning.

2. Use with caution for the first time: the first time you feed urea, you should feed it according to 1 10 of the daily amount of urea, and then gradually increase it, so that the rumen microorganisms can adapt to it for 10 days before you can feed the full amount.

3. Daily feeding in batches: The daily dosage cannot be fed in 1 time, but should be fed in 2 or 3 times. A certain amount of urea is first dissolved in water, and then sprayed on the dry material or mixed into the concentrate and fed.

4. Control drinking water after feeding: do not let the sheep drink water immediately after feeding urea-containing dry material, and should provide drinking water after 30 minutes of feeding. Do not dissolve urea in water for sheep to drink, that will cause sheep urea poisoning.

5. Cooperate 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, cornmeal, melon dry powder, etc.

6. Add protein feed: urea can not replace all protein feed, while feeding urea, it should also be supplemented with soybean cake, vetch or alfalfa and other protein-containing feed. It should be noted that soybean cake contains urease, which can accelerate the decomposition of urea, so it is not possible to mix soybean cake with urea.

If the crude protein content of the diet is higher than 12%, urea does not need to be added.

7. Supplement mineral elements: Appropriate amount of sulfur and phosphorus in the diet can improve the utilization rate of urea. Phosphorus can be supplied from bone meal, and sulfur can be supplemented with potassium sulfate or sodium sulfate.

8. Control the timing of feeding: for sick sheep and thin sheep, urea should not be fed;When the sheep is excessively hungry, do not feed urea immediately.

9. Must be used continuously: rumen microorganisms have an adaptation process to the use of urea, and continuous use can have the desired effect.

10. Prevention and treatment of urea poisoning: once urea poisoning occurs in sheep, it should be quickly injected with 10% 25% glucose solution, with 100 200 ml each time. Giving a kilogram of vinegar to the poisoned sheep also has a good first-aid effect.

Sheep belong to ruminants, and their rumen microorganisms can synthesize bacterial protein from non-protein nitrogenous feed such as nitrogen in urea, which can be digested and absorbed for their own body use. Therefore, urea can be fed to sheep.

Urea is not a true protein, as a special protein**, it must be decomposed and transformed in the rumen, and the transformation process and results are affected by many factors, which further affects the health of the animal.

1) The amount of urea added should account for about i% of the diet, generally each daily feeding amount of young sheep over 6 months old is 8 12 grams, adult sheep is 13 18 grams. The daily feed should not exceed 1 3 of the dietary crude protein requirement, nor should it exceed its body weight. (2) Feeding method mixed into feed, added to silage, sprayed on hay for ad libitum feeding, made into urea bricks for sheep to lick, or made into liquid urea concentrate, etc.

3) Precautions There must be a certain amount of carbohydrates, a certain proportion of protein (usually 10% and 12%), appropriate and balanced minerals, and an appropriate amount of vitamins in the diet to improve the utilization of urea.

Urea should be mixed evenly with the feed and feed intake should be limited to avoid overfeeding of sheep, especially hungry sheep.

Raw bean cakes, raw beans, bush clover seeds, alfalfa seeds or mustard seeds should never be mixed into urea-containing cereal feed, lest the urease of the seeds break down urea into ammonia and carbon dioxide, resulting in an ammonia smell that disgusts sheep.

Feeding urea should have a period of adaptation (generally 5 7 days), drinking water is appropriate, and the roughage before feeding urea-containing concentrate should not be too bad, so as not to increase the rumen pH after feeding.

Urea poisoning is prone to occur due to uneven feed mixing, excessive dosage, wrong proportioning, improper adaptation period, and poor roughage quality. The symptoms of poisoning are typical of ammonia poisoning: shortness of breath, muscle tremors, prolonged sweating, incoordination, and in severe cases, foaming at the mouth.

It usually appears 15 to 40 minutes after feeding, and if it is not timely**, it will die within hours. If poisoning is found, it can be treated with dilute acetic acid, yogurt, sour whey, vinegar or lactic acid**.

Sheep are ruminants, you know. Urea provides ruminants with sufficient non-protein nitrogen**, urea can be released and absorbed in the rumen of ruminants, and the microorganisms in the rumen can decompose the carbamic acid produced by urea when it meets water, so urea can replace part of the protein feed in the ruminant diet.

For monogastric animals, there is no "preconditioning" organ like the rumen of ruminants, and the carbamic acid produced by ammonia and water in urea can be toxic to the body.

Even ruminants should pay attention to the adaptation period when eating urea, and the amount in the feed should be appropriate, the stirring should be even, and it is better not to feed urea in a hungry state. 1.It can only be used by adult animals over 6 months of age, and is not suitable for feeding calves and lambs, and the amount does not exceed 1 3 total nitrogen in the diet.

Because the rumen function of juvenile livestock is not perfect, it cannot make good use of the ammonia released by urea, which is easy to cause ammonia poisoning. 2.Do not use with raw soybeans or soybean meal high in urease.

3.The dosage should be increased gradually, with a minimum of a three-week filtration period to complete the change.

Urea is a good protein additive for sheep, 1 kg of urea is equivalent to kg of crude protein, which is equivalent to -6 kg of soybean cake. Supplementing sheep with an appropriate amount of urea is an effective way to fatten, so how to grasp the dosage?

One method is to feed urea directly and evenly with concentrate by mixing it in the concentrate according to the amount of concentrate.

Another method is to make urea salt bricks for sheep to lick and eat. The ratio of urea salt bricks is 40% urea, 10% salt and honey, sodium phosphate, and a small amount of cobalt.

The third method is to mix the green fodder in a certain proportion when feeding the silage, and the correct ratio is 1000 kg of green fodder plus 5-6 kg of urea.

Pay special attention to the following points: Master the amount of urea to feed. The amount fed per day represents the weight of the sheep and does not exceed 1% of the dry matter in the diet.

The daily feeding amount of adult sheep is 10-15 grams, and the young sheep over 6 months old are 6-8 grams. However, the first feeding amount can only be fed according to the prescribed amount of 1 10, and then gradually increased, until the prescribed amount is reached after 10 days. Urea can not be fed alone, nor can it be fed in water, and it cannot be drunk immediately after feeding urea, and drinking water should be 30 minutes later.

Sick sheep and sheep with weak constitution should be fed less or no at all.

Feed the sheep, do you want the sheep to die.
