Spring is the shortage of green and green feed. Many cattle and sheep farmers supplement the feed of cattle and sheep by feeding silage, but silage is the fermentation of lactic acid bacteria under the condition of sealed anaerobic crop straw. Improper use and feeding methods can easily lead to deterioration of silage and poisoning. Therefore, the farmers should pay attention to the following matters when feeding cattle and sheep to silage in spring.

1, to ensure the quality of feed, pay attention to the quality of forage
The quality silage is green or yellowish brown with a scent of wine and a soft and soft texture. The veins and fluff on the stems and leaves can be seen. Poor quality sticks into a group, indicating that there is more water; some are loose, dry, and hard, indicating less water. When using silage, you must use high-quality feed. For black or dark brown color, smelly and smelly, even moldy, rotten, and spoiled should be thrown away immediately. Do not feed cattle and sheep. If cattle and sheep are fed with spoiled silage, it is easy to cause miscarriage.
During spring grazing (especially within 10 days of grazing), cattle and sheep must be prevented from eating grass and eating toxic foods at any time to avoid bloating or poisoning.
2, with forage to be diversified
High-quality grass with sub-grass, short grass with long grass, such as wheat straw and straw with green hay, eucalyptus leaves, peanut mites and valerian, etc., so that the mixed forage is full of nutrients, cattle and sheep love to eat. When feeding concentrates, soft and hard combination is required. For example, when feeding hard materials such as corn and soybeans, soft materials such as bran and powder should be added. At the beginning, you can feed the forage first. When the beef and sheep are half full, add a little concentrate. When you are full, add more concentrate, and add the flavored essence. For example, the soybeans are ground and mixed in the grass, even if Without grass, cattle and sheep can also eat enough. In the spring, the night is long, and it is necessary to feed it during the day. At night, it is necessary to feed a trough, and the grass is fed 13 to 15 kg per day.
3, feed feed should be appropriate
Silage has a sour taste. Some cattle and sheep may not be used at the time of feeding. The principle of feeding from small to large, step by step should be observed. The hay can be placed on the upper layer, and the silage on the lower layer is fed on an empty stomach to allow it to gradually adapt. In most cases, yaks can be fed silage after weaning. The daily feeding amount of adult cattle and sheep silage is 20-25 kg, and the post-weaning yak sheep should be 5-15 kg.
4, feed access to science
When silage is used, it must be taken from the beginning of the silo, according to a certain thickness, layered from top to bottom, to prevent the infiltration of soil, should not be digging through a hole. It is advisable to feed the amount of feed each day. In the early spring, there is still a phenomenon of micro-freezing. After the silage is taken out, the silo pool mouth must be closed immediately to prevent the silage from deteriorating due to cold weather and long-term contact with the air.
5, supplement energy feed
Adding urea is an important measure to supplement the protein of cattle and sheep. It can be fed in the winter and spring. Generally, the yak is fed 40-60 grams per day for more than half a year, 70-100 grams for fattening cattle, and 150 grams for adult cows. The urea has poor palatability. It can be mixed with 1% of the diet and mixed with the concentrate to feed the grass. It can't drink water within half an hour after feeding.
6, pay attention to scientific matching
Although silage is a kind of high-quality roughage, it must be scientifically matched according to the actual needs of cattle and sheep and the concentrate to improve the utilization of feed. As far as we are concerned, the ratio of feed for cattle and sheep to silage (water content) is more reasonable in the range of 1:3-1:3.5. If the silage has a large acidity, add 5%-10% baking soda or 1%-2% lime water to the feed, rinse and feed to reduce acidity, improve palatability and promote digestion and absorption.
7, pay attention to moisture
In spring, there is a lot of rain, the environment is humid, the bacteria breeds faster, and the cattle and sheep are susceptible to diseases. Therefore, it is necessary to diligently clear the circle, diligently, diligently and change the bedding, and occasionally sprinkle lime or grass ash in the house to disinfect the moisture. Keep ventilation in the house and keep the air fresh.
8, grazing must be temperate
When cattle and sheep are grazing in spring, they are bloated because of greed. Before grazing, they should feed the cows with the right amount of hay. At the same time, the grazing cattle and sheep should be fed a certain amount of night grass and mixed concentrate, and provide sufficient drinking water to let the cattle and sheep eat enough. The feeding sequence is to first drink water, then feed the appropriate amount of hay. When the beef and sheep are eaten at 50 or 60%, they are fed with mixed concentrate, and the cattle and sheep are fed with light salt water. After 15 to 30 minutes of rest, graze. Grazing back to the cattle and sheep to prepare enough water and night grass, let it freely drink and eat.

The above is the precautions for spring cattle and sheep to feed silage. In spring, it is necessary to adjust the method of feeding in time. Because temperature, environment and winter are completely different, it is a period of frequent disease of cattle and sheep disease. We must pay attention to the above problems and find that the disease should be treated in time. .
