摘要
研究蜂花粉对人工采精中采不出精液的公鸡的繁殖性能及内分泌机能的影响。结果表明:日粮中添加2%的蜂花粉,能显著改善公鸡的精液量、精子活力、精子密度和有效精子数(P<0.05),对精子畸形率影响不大(P>0.05),有效缓解血浆T水平的下降(P<0.05),对E2水平无明显影响;与对照组相比,添加蜂花粉后试验组血浆T3含量升高(P<0.05)、T4含量(P<0.05)和皮质醇含量(P>0.05)下降,说明蜂花粉改善了热应激公鸡的甲状腺功能和肾上腺功能。
The research was used to study the effect of adding bee pollen in diets on the multiplication and endocrine of breeder cocks which can not ejaculate under artificial fertilization. The results showed: the 2%treatment significantly improved the semen quantity,sperm activity,sperm density and available sperm(P≤0.05),but has little effect on the deformity of sperm(P>0.05),and no difference on estradiol,but respited the decrease of T in plasma.Compared with the control,concentration of thyroxine(T4) and testosterone decreased(P<0.05),at the same time,triiodothyronine(T3) concentration increased(P<0.05). The results showed:feeding cocks with the diet added bee pollen can improve the thyroid and adrenalin function.
