Four points of dairy cow silage

In the early spring, it is warm and cold, just as the green feed is scarce, and silage and crop straw become the main source of roughage for dairy cows. UUn China Feed Industry Information Network - based on feed, serving animal husbandry

Silage has the advantages of lower feeding cost, good palatability, improved utilization of crop straw, easy digestion, convenient preparation, long-term storage, and can increase the yield of dairy cows. Since silage is prepared by fermentation of lactic acid bacteria under the condition of sealed anaerobic conditions, if the method of improper use and feeding is improper, it will easily lead to deterioration of silage, causing cow poisoning and disease. Therefore, spring dairy cows must pay attention to the following four points when feeding silage: UUn China Feed Industry Information Network - based on feed, serving animal husbandry

Quality UUn China Feed Industry Information Network - Based on feed, serving animal husbandry

When using silage, you must use high quality silage. The quality silage is green or yellowish brown, the smell is fragrant, the texture is soft and moist, and the veins and fluff on the stems and leaves can be seen. For dark or dark brown color, silly smelly, even moldy, rotten, spoiled silage, do not feed the cows. Feeding these degraded silages can lead to diseases in the digestive tract of cows, which can cause miscarriage if they are eaten.

When using silage, it must be opened from the end of the silage, according to a certain thickness, from the top to the bottom layered to keep the surface flat, to prevent the soil from mixing, should not be digging a hole. It is advisable to feed the amount of feed each day. In spring, the weather gradually warms up, the reproductive speed of harmful microorganisms accelerates, and the contact time between silage and air is long, which is easy to cause mildew and deterioration of silage. Therefore, after the silage is taken out, the silage mouth should be closed immediately to prevent excessive air from entering the silo.

Silage has a certain sour taste. Some cows may not be used to it when they are first fed. They should follow the principle of less to many and gradual progress. Mix with other concentrates or hay, first place less silage, then gradually increase the amount, feed on an empty stomach, let it gradually adapt. Since silage contains a large amount of amino acids and has a laxative effect, the dams should not be fed more in the late pregnancy and should be stopped 15 days before delivery. Under normal circumstances, after the yak is weaned, it can be fed to silage. The daily feeding amount of adult dairy cow silage is suitable from 20 kg to 25 kg, and the post-weaning calf is in the range of 5 kg to 15 kg. As the feed of green feed is gradually increased, the amount of silage fed can be appropriately reduced. UUn China Feed Industry Information Network - based on feed, serving animal husbandry

Although silage is a kind of high-quality roughage, it must be scientifically matched with the concentrate according to the actual needs of the cows to improve the utilization rate of the feed. In terms of ingredients, the feed ratio of dairy concentrate to silage (water content) is more reasonable in the range of 1:3 to 1:3.5. If the silage has a large acidity, add 5%~10% baking soda or 1%~2% lime water to the feed. After washing, feed to reduce acidity, improve palatability and promote digestion and absorption.
