Deep litter system for raising cows and method for raising cows

Abstract

The invention relates to the technical field of livestock breeding, in particular to a deep litter system for raising cows and a method for raising cows. Biological bedding materials with the thickness of 50 cm-60 cm are arranged in the deep litter system and composed of raw materials comprising, by weight, 50-70 parts of solid cow dung obtained through solid-liquid separation after biological fermentation and high-temperature sterilization, 30-50 parts of chaff or coconut shell flour and 0.1-0.2 part of fermentation strains; the fermentation strains comprise proteases, amylases, bacillus subtilis and lactobacillus fermenti. The deep litter system for raising cows comprises the solid cow dung, so the use cost of the deep litter system is reduced; when cows are raised, beneficial microorganisms and microbial metabolites of the biological bedding materials will be eaten and absorbed by cows, and therefore the intestinal microbial environment is improved, ecological balance of intestinal flora is maintained, cow body metabolism is improved, and the feed conversion ratio is increased.

Description

technical field [0001] The invention relates to the technical field of poultry breeding, in particular to a biological bedding for raising cows and a method for raising cows. Background technique [0002] In recent years, the rapid development of my country's livestock and poultry breeding industry, especially the construction of a large number of dairy farms, has caused serious pollution and damage to our country's environment. At present, the cow manure treatment method still uses the traditional pen bedding, directly laying straw on the ground of the pen. This method has disadvantages such as poor sewage absorption ability, weak decomposition ability of waste such as feces and urine, short service life, and easy to cause livestock diseases. It cannot meet the requirements of promoting dairy cow growth, disease prevention, and pollutant discharge in modern dairy farming. Generally speaking, 20% of the productivity of livestock depends on the breed, 40% to 50% depends on t...

Problems solved by technology

At present, biological bedding has been widely used in poultry breeding such as pigs, and good results have been achieved. However, there is no method to apply biological bedding to dairy cow breeding, and a large number of technical difficulties need to be overcome in actual operation.
