Abstract:在27±1℃,自然明暗比条件下,用大豆、小麦、酵母粉为主要原料配成的人工饲料饲养甜菜夜蛾,幼虫发育历期为10-14d;蛹历期为6-9d;单头蛹重平均为97.97±1.76mg,范围为48-141mg。各代中,雌蛹重量高于雄蛹重量,蛹重有随从工谢增加而降低的现象。未交尾的雌蛾产卵前期延长,怀卵量与产卵量均明显少于正常交尾的雌蛾,但产卵期和存活天数差异不大。

Abstract:利用60头杂交组合试验猪从遗传和环境两方面探讨影响肉质的因素,结果表明,75-85V,2400-3000HZ的电击昏明显优于220V、50HZ,且对肉质无显著影响,肌肉温度若高于40℃,则对了长肌的PH值有显著影响;遗传材料不同,肌肉品质各异,因此,规范化的宰前处理和屠宰条件是正确评判肉质的前提,遗传材料是影响肉质的主要因素。
