First, the amount of feed should be modest According to local experience, the daily feed volume per cow is appropriate to 7-8 kg, production performance has improved significantly, no adverse effects on cattle. The daily feeding amount of lactating cattle does not exceed 10 kg (especially in summer) and the maximum limit is 15 kg.
Second, fresh beer must have a large water content and deteriorate quickly. Therefore, it must be fresh when feeding, and it should be properly stored when it is fed. The summer brewers' grains should be fed daily and at the same time 150 to 200 grams of baking soda per head can be added.
Third, pay attention to the nutritional balance Although the rich crude protein content of beer grains, but the calcium and phosphorus content is low and the proportion is not appropriate, so feeding should increase the nutrient concentration of the diet concentrate, and pay attention to calcium. It is recommended that bone meal account for 2% of the dietary concentrate, which is beneficial to milk production and the health of dairy cows.
Fourth, pay attention to the feeding period of lactation cows within 1 month postpartum should try not to feed or feed a small amount of brewers so as not to increase the nutritional negative balance and delay the recovery of the reproductive system.
Fifth, the timely treatment of poisoning in the treatment of chronic bad beer poisoning, we must immediately reduce the amount of feed and symptomatic treatment in time, especially for laminitis, must be treated as an emergency, or later bad.
