Breeding method of beef cattle

Abstract

The invention relates to the breeding of beef cattle, and provides a breeding method of the beef cattle. Weaning cattle are fed by the following materials in parts by weight in a matching manner: a crude feed, a concentrated feed and a green feed, wherein the concentrated feed comprises the following components in parts by weight: 30-40 parts of corn, 8-15 parts of rape seed cakes, 5-9 parts of bran coat or bran, 15-20 parts of bean dregs, 25-30 parts of ammonified whole-plant corn straws, 5-7 parts of Chinese herbal medicine components, 0.5-0.8 part of dicalcium phosphate, 0.2-0.3 part of a beef cattle trace element additive, 0.3-0.5 part of table salt, 0.4-0.6 part of rumen-protected lysine, and 0.3-0.5 part of rumen-protected methionine; the concentrated feed also contains lipase of which the enzyme activity is over 6000U / g, and the dosage of the lipase is 0.6-0.8g for each kilo of the concentrated feed. According to the breeding method disclosed by the invention, in fact, the utilization rate of the concentrated feed is increased, and the raw materials which are beneficial to the growth and the development of the beef cattle are added to the concentrated feed, so that the digestibility of the beef cattle for the concentrated feed and the crude feed is increased, the breeding cost is reduced, and the breeding economic benefits are provided.

Description

technical field [0001] The invention relates to livestock breeding, in particular to a beef cattle breeding method. Background technique [0002] With the rapid development of animal husbandry, the breeding and production structure has been gradually adjusted, and the large-scale breeding and industrialization of beef cattle has progressed rapidly. Making full use of my country's existing roughage resources to develop grass-fed livestock production dominated by beef cattle will be an important way to solve my country's per capita grain shortage and reduce the consumption of refined grains in the breeding industry. [0003] Roughage, as an important nutrient source for the growth of beef cattle, refers to the feed with natural moisture content below 60%, crude fiber content in dry matter greater than or equal to 18%, and fed in the form of air-dried food. Such as beet pulp, crop straw, distiller's grains, etc. The nutritional value of roughage is generally lower than other ...

AI Technical Summary

Problems solved by technology

Nutrients such as dry matter, organic matter, crude fiber and crude protein contained in roughage are difficult to be digested by beef cattle, and the nutrient utilization rate is low

[0004] However, green fodder resources such as fresh grass are limited, and the cost of concentrated fodder is relatively high.
