錳元素（天門冬氨酸錳Manganese Aspartate）在羊生產繁殖中的關鍵作用

在羊的養殖過程中，飼料中錳元素（天門冬氨酸錳Manganese Aspartate）的合理添加對羊的生產繁殖意義重大。錳不僅有助于提高公羊精液品質，還能提升母羊的產奶量與平均日增重，促進羊生殖器官正常發育。錳（天門冬氨酸錳Manganese Aspartate）對羊體內的激素調節影響顯著，能借助二甲戊酸激酶等酶的酶促反應來調控性激素分泌。Silva 等的研究顯示，給公綿羊飼料中添加錳，可降低其血清中雌二醇含量，增加睪酮水平，進而提升精子品質。這是因為雌二醇會通過反饋調節或抑制間質細胞，阻礙睪酮的合成分泌，而缺錳時雄性羊的睪丸和曲精管易退化，嚴重時甚至喪失生殖能力。補飼錳（天門冬氨酸錳Manganese Aspartate）對母羊同樣影響深遠。妊娠初期，在飼料中添加 40 mg/kg 干物質的錳，能顯著增強母羊血清抑制羥自由基（OH）生成的能力，增強抗病力。發情配種時補錳，可提高配種成功率。錳（天門冬氨酸錳Manganese Aspartate）還能促使母羊分泌雌激素，促進卵巢發育、增加排卵，提高受孕率并延長孕育年份。錳缺乏則會導致母羊激素紊亂，引發卵巢囊性病、發情異常、排卵障礙、流產等問題。此外，在母羊妊娠期添加錳，能刺激分泌足夠的雌雄激素，促進胎兒性別分化與器官發育，防止胚胎畸形。

The key role of manganese (manganese aspartate) in sheep production and reproduction

In the process of sheep breeding, the reasonable addition of manganese (manganese aspartate) in the feed is of great significance to the production and reproduction of sheep. Manganese not only helps to improve the quality of ram semen, but also improves the milk production and average daily weight gain of ewes, and promotes the normal development of sheep reproductive organs. Manganese (Manganese Aspartate) has a significant effect on hormone regulation in sheep, and can regulate the secretion of sex hormones with the help of enzymatic reactions of enzymes such as valproic acid kinase. Silva et al.'s study showed that adding manganese to ram feed could reduce serum estradiol levels and increase testosterone levels, which in turn improved sperm quality. This is because estradiol will regulate or inhibit interstitial cells through feedback, hindering the synthesis and secretion of testosterone, and when manganese deficiency occurs, the testicles and seminiferous ducts of male sheep are prone to degeneration, and even lose reproductive ability in severe cases. Supplemental feeding of manganese (Manganese aspartate) also has a profound effect on ewes. In the early stages of gestation, the addition of 40 mg/kg of manganese dry matter to the feed can significantly enhance the ability of ewe serum to inhibit the formation of hydroxyl radicals (OH) and enhance disease resistance. Manganese supplementation during estrus breeding can improve the success rate of mating. Manganese (Manganese Aspartate) can also promote the secretion of estrogen by ewes, promote ovarian development, increase ovulation, increase pregnancy rate and prolong gestation years. Manganese deficiency can lead to hormonal disorders in ewes, causing problems such as ovarian cystic disease, estrus abnormalities, ovulation disorders, and abortion. In addition, the addition of manganese during the gestation period of ewes can stimulate the secretion of sufficient estrogen and androgen, promote fetal sex differentiation and organ development, and prevent embryonic malformation.
