摘要
本文用运数学模型对藏系绵羊最佳屠宰年龄进行了模似。模型所涉及的参数可容易得到,且能较好的反映藏系绵羊的投入、产出过程。因此,模型具有实用性和准确性。模拟结果表明,在羔羊胴体偏小的藏羊产区,绵羊的最佳屠宰年龄为22月龄,这时绵羊的胴体重可达30斤以上(15.41公斤),且能剪二次毛。
In this paper we employ a mathematical model to strdy the optimum slaughter age of Tibetan sheep. This is first time that such a mathematical model has been applied by us. From the simulated results, the optimum slaughter age of Tibetan sheep is 22 months old. It is proved that the model is highly accurate and is suilable for the simulation the optimum slaughter age of Tibetan sheep.
