The silage that entered the pits after 45 days of fermentation turned into a high-quality silage with soft texture, sweet and sour taste, and nutrient richness. When feeding silage to dairy cows, attention should be paid to the following issues in order to give full play to the role of silage, ensure the physiological health of dairy cows, and improve the production performance of dairy cows. 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. For lactating cattle with a body weight of 500 kg and a daily milk production of 25 kg or more, 25 kg of silage and 5 kg of hay can be fed daily. Dairy cows with a milk yield of more than 30 kg per day can feed 30 kg of silage and 8 kg of hay.
2. Cows with a body weight of 350-400 kilograms and a daily milk yield of 20 kilograms can feed 20 kilograms of silage and 5-8 kilograms of hay.
3. Cows with a body weight of 350 kg and a daily milk yield of 15-20 kg can feed 15-20 kg of silage and 8-10 kg of hay.
4. Dairy cows with a milk output of 15 kg or less daily will be fed with 15 kg of silage and about 10-12 kg of hay.
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. For silage or other roughage, it is best to feed 3 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 in the countryside. Feeding twice a day is extremely unscientific.
(1) Increased burden on the rumen of dairy cows, affecting 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.
(2) Affecting the feed digestibility of dairy cows, resulting in decreased milk production and milk 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.
