Method for breeding small-tailed Han sheep in fattening period in summer high-temperature environment

Abstract

The invention relates to the technical field of animal breeding, and particularly relates to a method for breeding small-tailed Han sheep in a fattening period in a summer high-temperature environment. A semi-open house free-ranging mode is adopted, and the method comprises the steps of colony house site selection, colony house heat insulation construction, scientific management, combination of separate house feeding and grazing, colony house environment optimization, scientific immunization and epidemic prevention disinfection, timely slaughtering and the like. The advantages of the semi-opengrazing breeding of the small-tailed Han sheep are fully exerted; growth and development characteristics of the small-tailed Han sheep are kept, a good growth environment is provided for the small-tailed Han sheep, the sheep are cooled by combining multiple cooling modes such as natural cooling and forced cooling, the defect of summer fattening of the sheep is overcome, the fattening efficiency and effect are improved, and the whole method is simple, easy to operate and low in cost and has practical significance.

Description

technical field [0001] The invention relates to the technical field of animal breeding, in particular to a breeding method for small-tailed Han sheep during the fattening period in a high-temperature environment in summer. Background technique [0002] Small-tailed Han sheep has the advantages of large body, early maturity, fast growth and development, estrus in four seasons, multiple births and high yield, and rough feeding tolerance. In midsummer, with the increase of rainwater, a large number of mosquitoes and flies increase the probability of disease transmission, resulting in an increased risk of animal epidemics in summer and causing certain difficulties in summer breeding. [0003] For the animals themselves, the continuous high temperature stress in summer will not only reduce the excitability of the feeding center, reduce appetite, reduce feed intake, slow down the peristalsis of the digestive tract, weaken the role of gastrointestinal digestive enzymes, but also ch...
