Concentrated calf fodder and use method thereof

Abstract

The invention relates to fodder and a use method, in particular to concentrated calf fodder and a use method thereof. The fodder comprises protein fodder and a premix compound, wherein the protein fodder is prepared from raw materials of bean cakes, corn protein powder, cotton dregs, complex enzymes, and the like; and the premix compound is prepared from common salt, fluorspar powder, magnesium sulfate, sodium diacetate, calcium hydrogen phosphate, soda, sodium humate, monensin, vitamins and trace elements of copper, iron, manganese, zinc, cobalt, and the like. The use method comprises the following steps: manually feeding calves at age of 3-5 days with a mixture of the concentrated calf fodder and a certain amount of milk; and stopping feeding the milk when the calves are at age of 60 days; and coming into a fatting period when the calves are at age of 120 days. The calf fodder has complete nutrients, reasonable proportion and low cost and is fed to the calves in a suckling period to substitute a great amount of milk, improve the commodity rate of the milk, facilitate the growth and the development of the calves, shorten the suckling period by 50 percent, increase the weight-gaining speed by about two times, shorten the deliver time by one half, increase the current fertility rate of milk cows by about two times, realize perennial milking, facilitate mechanical milking and scaled stabling management and remarkably improve the economic benefits, the social benefits and ecological benefits of cattle rearing in a plurality of aspects.

Description

technical field [0001] The invention relates to a feed and its usage, namely a concentrated feed for calves and its usage method. Background technique [0002] Dairy cows can only produce milk after calving, and part of the milk produced is for the calf to feed, and the rest becomes commercial milk. At present, calves of cattle live with cows and grow up on the milk of their mothers. There are many disadvantages of this method. First, a large amount of milk is eaten by calves, and the production of commercial milk is very small, which greatly affects the income of milk. The second is to feed calves for a long time, reduce the conception rate of dairy cows, and reduce the number of calving in the second year. The 3rd, cow and calf are accompanied, are unfavorable for mechanized milking, will knock cow's udder with calf every time during mechanical milking, after causing conditioned reflex, just can carry out mechanical milking, very inconvenient. Fourth, the calves that ar...

AI Technical Summary

Problems solved by technology

The third is that the cow and the calf are accompanied, which is not conducive to mechanized milking. Every time the machine is milked, the calf must be bumped into the breast of the cow, and the mechanical milking can only be performed after the conditioned reflex is caused, which is very inconvenient.

Fourth, calves that are mainly breast milk grow slowly and keep for a longer period of time

Dairy cows can only produce commercial milk after 120 days, and the annual milking days are only about 120 days, so milking can not be realized all year round, and the milk production income is greatly affected, and the mother and child companionship significantly reduces the conception rate of cows, and the calving rate in the second year is lower than 50% %

The benefit of raising cattle is very low, and the animal husbandry economy is subject to certain restrictions
