不同高氟日粮添加硒对绵羊机体营养物质消化代谢的影响

为了研究不同高氟日粮与硒相互作用对绵羊机体营养物质消化代谢率的影响。选16只健康的蒙古公羊,体重(35.0±1.4) kg,随机分组,4只羊为一组,分批进行试验,测定营养物质消化代谢率。日粮1(35∶65精粗比)有助于机体对营养物质的消化吸收;在日粮1条件下,硒能促进氟的排泄,能起到一定的解毒作用。适量的氟与硒摄入有利于机体的健康,硒在一定浓度范围内对高氟引起的毒害起颉颃作用,提高日粮精料水平会促进机体氟的排泄,降低氟的生物学利用率,日粮1(35∶65精粗比)比日粮2(30∶70精粗比) 更能促进营养物质的吸收。

Different Fluoride Dietary and Selenium Affect Digestion and Metabolism of Nutrients on Sheep Body

In order to study the different levels of fluoride dietary and selenium interact effect on nutrients digestion and metabolism on sheep,16 healthy Mongolia rams, weight (35.0 ± 1.4) kg, were randomly assigned to a group of four sheep, batch experiments to determine rate of digestion and metabolism of nutrients. Diet 1 helps the body digest and absorb nutrients, diet 1 selenium can promote the excretion of fluorine,can play a detoxification role. Amount of fluorine and selenium intake is conducive to the health of the body, selenium in a certain range of concentration of fluoride toxicity arising from the antagonistic role in enhancing the level of concentrate diet will promote the body's excretion of fluoride and reduce the bioavailability of fluoride, the absorption of diet 1 nutrients can be enhanced.
