Brewers cattle breeding technology

The beer grains are dregs. According to relevant reports, fresh brewers' grains are added to the dairy cow diet instead of corn silage, soybean meal and wheat bran to increase the crude protein content from 35% to 39%, which can significantly increase the daily milk production. Quantity, milk fat content and milk total dry matter content.

The direct feeding of brewer's grains is usually done in the fattening of young bulls. The use of distiller's grains accounts for about 40% of the dry matter of the feed, and it can reach as high as 60%. When the shelf ox generally accounts for 30%~35%, the effect is better and the carcass quality can be improved. Grade, and no harm to cows. According to the farmer's experiment, a large amount of brewers' grains was used to feed fattening cattle during the whole season of fortification, with an amount of 20 kilograms per cow per day, supplemented with concentrate feed and buffer, and the average daily gain of cattle was over 1000 grams without any problems. .

The brewer's dregs and chicken manure are mixed and fermented. The lactating dairy cows are then mixed with the fresh brewers' grains and the chicken manure after being mixed. The mixture is mixed uniformly and then loaded into a pre-prepared concrete pool and fermented for 1 week. The feeding results show that although the cows The average daily milk production and body weight gain were lower than those of the control group, but the feed cost was significantly reduced.

After the brewers' micro-storage, the cattle will cut the corn stalks into pieces of 2 cm to 4 cm in size, mix them with the ratio of 1:5 of the fresh lees that have been evaporated, and control the water content of the straw at about 55%. Then it was put into the tank and fermented for 30 days. Feeding the lactating dairy cows with this mixed stock can obviously increase the feed intake, milk production and feed conversion rate.

After the malt root micro-storage was added to the beer malt, 7.5% of the malt root was added after the malt root micro-reservoirs. The micro-storage under the effect of the high-efficiency complex bacteria increased the dry matter content from 25.03% to 30.1% and the crude protein content. From 7.5% to 8.20%, the results of feeding cows showed that under the same conditions, the test group fed micro-breweries dregs had a 3.75% increase in milk fat content compared with the control group fed fresh lees. , Daily milk production increased by 3%.

Attention should be paid to the proper amount of feed for the sake of feeding malting brewers. The daily feed volume per cow is appropriate from 7 kg to 8 kg, and the production performance is obviously improved without 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.

Try to feed fresh breweries. Brewer's grains have large water content and deteriorate quickly. Therefore, they must be fresh when feeding, and should be properly preserved when they are fed for a time. If storage is required, the effect of pit storage is good. In summer, the brewers' grains should be fed daily, and 150 grams to 200 grams of baking soda per head can be added daily.

Pay attention to keeping the nutritional balance. Although the crude protein content of brewer's grains is abundant, the content of calcium and phosphorus is low and the proportion is not appropriate. Therefore, the nutrient concentration of dietary concentrate should be increased when feeding, and calcium supplement should be noted at the same time. Bone meal accounts for 2% of the dietary concentrate, which is beneficial to the health of the cow. If the cow is fed, it is beneficial to the production of milk.

It is not appropriate to use the bad residue feed as the only coarse material for the diet. It should be mixed with dry coarse material and silage; in combination with silage, sodium bicarbonate should be added to the diet.

Pay attention to the feeding period. For lactating cows within 1 month after delivery, they should not feed or feed a small amount of brewer's grains, so as not to exacerbate the nutritional negative balance and delay the recovery of the reproductive system.

Deal with it in time after poisoning. In the case of chronic poisoning when feeding brewer's grains, it is necessary to immediately reduce the amount of feed and timely symptomatic treatment, especially for laminitis, must be treated as an emergency, or it will be worse afterwards.
