酵母硒、无机硒对不同品种母猪繁殖性能、仔猪组织中硒沉积影响的研究

Effects of Selenium Yeast,Inorganic Selenium on the Reproduction Performance of Sows and the Selenium Deposition in Tissues of Piglet

为了研究酵母硒和无机硒对不同品种母猪繁殖性能的影响及硒沉积规律,试验选择长白母猪和藏母猪各18头,在日粮中分别添加0.3mg/kg亚硒酸钠和0.2、0.5mg/kg酵母硒,对不同品种母猪的繁殖性能、母乳中硒沉积及哺乳仔猪组织中硒存留进行了研究。结果表明,添加0.2、0.5mg/kg酵母硒后,母猪繁殖性能有改进;酵母硒较亚硒酸钠能显著提高初乳、常乳及仔猪组织中硒含量,特别是肌肉中硒含量;不同品种母猪对酵母硒的需求量有所不同,硒沉积的规律也有所不同。

To study the effects of selenium yeast and inorganic selenium on reproductive performance of sows in different varieties, and provide scientific basis for the reasonable application of selenium yeast and study on selenium deposition, each 18 Landrace sows and Tibet sows were fed in diets adding 0.3 mg/kg sodium selenite and 0.2, 0.5 mg/kg of selenium yeast. The effects of selenium yeast on the reproduction performance, selenium deposition in milk and in organization of suckling piglets were studied. The results showed that selenium yeast had improvement effect on the reproductive performance of sows, compared with the sodium selenite, selenium yeast could significantly increased the selenium deposition in colostrum, milk and piglet tissues, especially in muscle, different varieties sow had different demand for selenium yeast, selenium deposition had different rules in different varieties.
