甘肃鼢鼠粪尿气味对侵占行为的影响

The Gansu zokor ( Myospalax cansus) is a solitary fossorial rodent, which inhabits its own tunnel system. The Gansu zokor are highly aggressive, and encounters between of two animals may end in the death or injury of one of them. In order to investigate the effect of fecaluria odor of the Gansu zokor on its invading behaviour, the behavioral methods were used to determine whether Gansu zokors use faeces to mark their own territorial boundaries and the effect on its excavation pattern. The results showed that when an intruder was introduced, the test animal almost always shifted its latrine location to the intruder’s side. The Gansu zokor can detect the conspecific odor. In nonbreeding season, the odor of urine and faeces of Gansu zokors prolongs excavation of homosexual intruders and play a role in delaying conspecifics from entering the territory .

丝兰提取物产品饲喂荷斯坦奶牛对其粪尿气味及生产性能影响

试验旨在研究荷斯坦奶牛日粮中添加丝兰提取物产品是否能消除或是减弱其尿液中氨氮含量,从而降低粪尿臭味,提升牛舍内空气质量;同时研究对奶牛生产性能的影响。以丝兰提取物产品添加量3 g/d·头,试验期90 d为条件进行试验。结果显示,丝兰提取物产品可降低奶牛尿液中氨氮含量,提高生鲜乳蛋白含量。因此得出结论,日粮添加丝兰提取物产品可以缓解牛舍粪尿臭味,提升奶牛生产性能。
