Technical guidance for dairy cows feeding silage
Feeding quantity The amount of silage administered should be determined based on the weight of the adult cow and the amount of milk produced. 1. A lactating cow with a body weight of 500 kg and a daily milk production of 25 kg or more can feed about 25 kg of silage each day and about 5 kg of hay; a milking cow with a daily milk output of over 30 kg can feed 30 kg of silage and hay. 8 kg or so. 2. For lactating cattle with a body weight of 350-400 kg and a milk yield of 20 kg per day, 20 kg of silage and 5-8 kg of hay can be fed. 3. Cows with a body weight of 350 kilograms and a daily milk yield of 15-20 kilograms can feed 15-20 kilograms of silage and 8-10 kilograms of hay. 4. Dairy cows with a daily milk output of 15 kg or less have 15 kg of silage and 10-12 kg of hay. 5. Feeding of silage should be stopped 15 days before and 15 days after delivery. 6. Dry-milk cows are fed 10 to 15 kg of silage each day, and other supplies of hay are appropriate. 7. The amount of silage fed to the breeding cattle should be less, preferably within 5-10 kg. 8. For young animals, feed less or not. Feeding method 1. When feeding, you should feed less at the beginning, and then gradually increase to enough to allow the cow to adapt. Must not be fed at one time in sufficient quantities, resulting in too much silage in the rumen of dairy cows and excessive acidity, which will affect the normal feeding and milk production performance of dairy cows. 2. Baking soda should be added to the cows in time. When the silage is fed, the pH value of the rumen of the cows is reduced, and acidosis can easily occur. It can add 1.5% baking soda to the concentrate to promote gastric peristalsis, neutralize acidic substances in the rumen, increase pH, increase feed intake, increase digestibility, and increase milk production. 3. Each time feed silage should be evenly mixed with hay, then fed to dairy cows to avoid picky eaters. Conditional dairy cows, it is best to fully stir the concentrate, silage, and hay to produce a "full-mix diet" to feed the cows. The effect will be better. 4. Silage or other roughage is best fed 3 times or 4 times a day to increase the number of ruminants in the cow. Cows produce and swallow saliva during rumination, helping to buffer stomach acid, promoting nitrogen recycling, and promoting digestion and utilization of feed by microorganisms. There are many dairy cows who feed twice a day are extremely unscientific. The first is to increase the burden on the rumen of dairy cows and affect the number and time of normal rumination in dairy cows. The conversion rate of feed is reduced, and in the long term it can easily cause cow's stomach disease. The second is to affect the digestive rate of dairy cows, resulting in decreased milk production and fat percentage. 5. Frozen silage cannot be fed to dairy cows. It must be thawed before feeding, otherwise it is easy to cause miscarriage in pregnant cattle. Access method 1. It is advisable to take one time each time in the morning and in the afternoon. The thickness of each time taken should be not less than 10 cm to guarantee the fresh quality of the silage, good palatability, and minimize the nutrient loss to feed the silage. The best results. 2. Remove the silage can not be exposed to sunlight, do not bulk heap, scattered, it is best to use bags, placed in the cow house in the shade. 3. After taking the silage each time, press it again and then cover it with plastic cloth. Precautions 1. During the feeding process, if dairy cows are found to have diarrhea, they should immediately reduce or stop feeding. Check whether silage is mixed with moldy silage or other disease causes dairy cows to diarrhea. Continue feeding after returning to normal. 2. To clear the feeding trough in time, especially in the corners, clean up the degraded silage and then feed the fresh silage. 3. After feeding silage, the amount of concentrate feed should be reduced as appropriate, depending on the amount of milk produced by the cow and the amount of feed, but it should not be reduced too much or too quickly. 4. The silo and silage should be strictly protected against rodents and avoid transmitting diseases to cows.
