In recent years, more and more farmers are feeding whole-plant corn silage of dairy cows, and rational use of whole plant silage has brought considerable economic benefits to dairy farmers. However, due to the lack of experience of some dairy farmers, there is no comprehensive and systematic understanding of the properties of the whole plant silage. Feeding this large amount of watery, high acidity roughage on a single basis causes the cow's metabolic disease, acidosis, and stomach displacement. The increase in the number of dairy cows caused miscarriages and premature birth. It also brought some undue losses to dairy farmers.
Whole plant silage is rich in sugar, crude protein and vitamins and is a good cow roughage. However, its crude fiber and mineral content are insufficient. In particular, the lack of crude fiber dry matter, high acidity, easy fermentation is its weaknesses, we should make full use of advantages in the use, to avoid its own lack of harm to us, and hay (grass) L. can supplement it The lack of. Dairy farmers are advised to add some hay or yew as appropriate when feeding the spiked silage. This will not only fully exploit the benefits of the silage silage, but also avoid the harm that may be caused to dairy cows due to its own lack, and to raise healthy and productive dairy cows.
A cow with a weight of 600 kg and a milk yield of 30 kg or more must incorporate no less than 3 kg to 5 kg of hay per day in the diet, and 2 kg of legume hay can be blended in the place where conditions permit. The feeding amount of the material is 10 to 13 kilograms, which can exert the maximum milk production potential of cows on the premise of keeping the cows healthy and healthy.
Diets added to dairy cows must not be soaked in water. Roughage (silage + hay + legume forages) is blended evenly and dry powder concentrate is fed into the trough. There is enough clean tap water in the trough to allow the cow to drink water freely.
Some dairy farmers fed roughage with spike silage, bean curd residue, starch residue, and brewer's grains. The amount of hay feeding should also be increased in the roughage of these dairy cows, so as to meet the needs of dairy cows for crude fiber, otherwise the dairy cows will still have an accident.
A small amount of hay should be added to the roughage fed to the calf after weaning, and 1 kg to 2 kg of hay should be included in the diet of the breeding cattle from 6 months to 24 months. The roughage fed to the cow should preferably have more than three types of hay. The combination of forage grasses is beneficial to the body of the cattle and the cultivation of high-quality reserve cattle with large body size and high milk yield.
