Organic Selenium Animal Feed Yeast Selenium Nutritional Supplement For Livestock And Poultry:

INTRODUCTION

Yeast selenium is produced from many advanced process , choose special yeast species and Cane molasses , after deep liquid fermentation cultivation in selenium- rich environment , then wash , separate , concentrate and spray dry the se-enriched yeast , then the yeast selenium contains various organic selenium such as selenium methionine , selenium cystine etc . The total organic selenium is more than 98% . Is the important internal micro element that with good oxidation resistance , stress resistance ,To Promote fertility, Improve The immunity and The quality of feedings .

The efficacy of yeast selenium in animal feed

1. The absorption and metabolism of yeast selenium in livestock and poultry: The absorption of selenium in the animal intestine varies due to its different forms. Inorganic selenium is mainly passively absorbed in the small intestine, while organic selenium is actively absorbed in the form of amino acids; When selenium yeast is added, selenium is mainly excreted from feces, and most of the absorbed organic selenium is retained in muscle tissue, reducing the total excretion. Compared with inorganic selenium, it is reduced by 16% to 19%, and the utilization rate is significantly improved. Yeast selenium (mainly selenomethionine) can be converted to selenocysteine through sulfur conversion, and then β Under the action of lyases, it is reduced to hydrogen selenide for the synthesis of selenoproteins, and can also be deposited into tissues through the methionine pathway.

2. The effect of yeast selenium on livestock and poultry: The effect of yeast selenium on the growth and development of livestock and poultry Selenium is an essential trace element in animal bodies and plays an important role in animal growth and development. Through feeding studies on weaned piglets and growth finishing pigs, it was found that the level and source of selenium did not significantly affect the production performance of pigs after reaching normal requirements. In the basal diet with a selenium content of 0.18 mg/kg, different selenium sources and levels of supplementation had no significant effects on the daily weight gain, feed intake, and feed to weight ratio of growing and fattening pigs. Early research found that selenium deficiency in animals can cause a decrease in the activity of deiodinase I, reducing the synthesis of T3 (the main hormone that plays a physiological role in the body), and thus inhibiting animal growth. Researchers have found that adding 0.3 mg/kg and 0.4 mg/kg yeast selenium to the diet significantly increased serum T3 content and decreased feed to meat ratio (P<0.05), indicating that adding organic selenium to a low selenium diet is more beneficial for body growth.

3. The effect of yeast selenium on livestock and poultry reproduction: Selenium deficiency can lead to a decrease in animal reproductive performance. Adding selenium to pig diets can increase litter size and reduce piglet mortality. Throughout the growth and reproduction process of sows, feeding 0.15 mg/kg selenium rich yeast had a similar effect on their reproductive performance compared to feeding inorganic selenium. However, feeding organic selenium resulted in a lower stillbirth rate. The level of selenium in the diet also has a significant impact on semen quality and fertilization rate. Adding 0.5 mg/kg selenium to the diet can improve the sperm motility and fertilization ability of boars, further confirming that low sperm motility is related to sperm ATP concentration and selenium deficiency. The change in sperm ATP concentration is caused by abnormal mitochondrial structure, and there is a selenium containing protein in the outer membrane of mitochondria. Therefore, it can be inferred that this selenium containing protein plays an important role in maintaining sperm mitochondrial structure. Organic selenium can increase the selenium content in breeding eggs, thereby improving the physiological and internal environment in the later stages of breeding eggs and enhancing the adaptability of embryos. Progesterone may be an important factor that stimulates the secretion of luteinizing hormone. Progesterone in poultry plasma mainly comes from granulosa cells of follicles. The concentration of progesterone in hens before ovulation is much higher than during the ovulation cycle. Therefore, adding yeast selenium to the diet of laying hens can increase egg production and improve reproductive ability.

4. The effect of yeast selenium on meat quality of livestock and poultry: Yeast selenium also has significant advantages in regulating meat quality. Compared with adding sodium selenite, yeast selenium has lower muscle drip loss after 24-72 hours of slaughter. Feeding broiler chickens with yeast selenium had no significant effect on the muscle fiber diameter of yellow feathered broiler chickens throughout their growth period, but it could significantly reduce the dripping loss of 70 day old muscles. Eggs produced by laying hens fed with yeast selenium have a longer shelf life than those produced by regular laying hens. In summary, adding yeast selenium to feed can improve the reproductive ability of livestock and poultry, improve meat quality, and increase selenium deposition in the body. Moreover, adding yeast selenium to low selenium diets is more conducive to the growth of livestock and poultry.
