不同毛鸡只重对产品出成和综合售价影响的研究

以规模养殖的罗斯308毛鸡为研究对象,探究不同毛鸡只重对产品出成和综合售价的影响。以单因素实验,重点研究了毛鸡只重对肉鸡各部位出成、主副产品出成以及总出成和综合售价的影响。结果显示:不同只重毛鸡与腿产品、胸产品及主产品出成呈正比关系,翅产品出成随只重的增加呈先增加后下降的走势,副产品出成与只重呈反比关系。同时,根据毛鸡只重对出成和售价的影响分析,车间屠宰分割的最佳只重为2. 55kg。在此只重下,有较高出成率88. 23%和最高综合售价10 840元/t。以此来确定肉鸡屠宰车间毛鸡的最佳只重范围,实现车间最大化价值生产。

Advanced Agriculture of Israel Roots in its Decision Making Mechanism

In the past 70 years, Israel has not only realized the self-sufficiency of agricultural products, but also make its way to becoming one of leading exporters of agricultural products in the world rapidly. Undoubtedly, there are many reasons for this world famous "Miracle of Negev Desert" [1], but we consider the decision making mechanism as one of the most important reasons, because such a perfect integrated system consisting of researching system, experimental system and extension system is well organized and it booms the development of agriculture in Israel.
