Premix feed for fattening beef cattle

Abstract

The invention relates to a premix feed for fattening beef cattle. Each kilogram of the premix feed for fattening beef cattle comprises 50000-200000 IU of vitamin A, 1000-40000 IU of vitamin D3, 250-800mg of vitamin E, 0.12-3g of nantokite, 0.8-9g of iron salt, 1.5-3.7g of zinc salt, 0.12-3.7g of manganese salt, 5-245mg of iodate, 2.5-12.4mg of selenium salt and 30-50g of bacillus subtilis. The premix feed for fattening beef cattle can effectively strengthen the rumen motility of the beef cattle, improve rumen acidosis condition of the beef cattle at the fattening later stage of beef cattle, shorten fattening time, reinforce fattening and weight increment effects, besides, increase the brightness of hair canals and improve the smell of excrement and urine.

Description

Technical field: [0001] The invention relates to a premixed feed, in particular to a premixed feed for fattening beef cattle. Background technique [0002] The fattening period of beef cattle refers to the process from breeding cattle weighing 250 kg to slaughtering cattle weighing 700 kg. This process can be divided into two stages. The first stage refers to the early stage of fattening when the weight of beef cattle is from 250 kg to 400 kg, and the second stage refers to the late stage of fattening when the weight of beef cattle is from 400 kg to 700 kg. Generally, it takes more than 12 months for beef cattle to fatten from 250 kg to 700 kg. [0003] The fattening time of beef cattle is affected by various factors such as the breed of beef cattle, improvement algebra, nutritional level, feeding management, and climate and environmental conditions. Due to the impact of the grazing prohibition policy, a large number of beef cattle are fattened in captivity. Due to the la...

AI Technical Summary

Problems solved by technology

Due to the impact of the grazing prohibition policy, a large number of beef cattle are fattened in captivity. Due to the lack of sufficient exercise and the lack of high-quality forage to provide nutrition, the slaughter cycle of beef cattle is greatly extended

In order to shorten the slaughter cycle and improve economic benefits, most breeders use a large amount of supplementary feed as a means of fast fattening beef cattle. Due to the excessive starch in the supplementary feed and the lack of good fiber, the beef cattle appear slow in weight gain in the late fattening period. In severe cases, symptoms of ruminal acidosis such as salivation, trembling, and numbness will appear, which will seriously affect the weight gain effect in the later stage of fattening

At the same time, the death of beef cattle will occur in the later stage of rumen acidosis, which will bring huge economic losses to the breeders.
