Optimization Model for Captive Breeding of Lake Sheep Based on Space Utilization

Abstract

 Power Lake sheep have excellent characteristics such as fast early growth, early sexual maturity, four-season estrus and can be kept in captivity, etc. It is of great significance to explore the development of appropriate production plans to improve the space utilization of farms in order to increase the annual turnout of lake sheep. In this paper, under the condition of continuous production, in order to determine the reasonable number of breeding rams and basic ewes in the farm and estimate the range of the annualized number of sheep, we used a set of inequalities to depict the breeding cycle of the lake sheep from the spatial and temporal dimensions, and established a model to analyze the number of annualized number of sheep under the condition of deterministic factors, and based on the analytical model, we solved the gap between the number of standard sheep pens and the number of standard sheep pens in the existing one, under the requirement of the farms to have not less than 1500 sheep pens per year. gap in the number of standard sheep pens. On the basis of the above model, taking into account the influence of uncertain factors such as the success rate of mating, the number of lambs delivered and the mortality rate, an optimization algorithm for fluctuating reproduction of lake sheep was adopted to achieve the optimization of the production plan in order to maximize the economic benefits.
