在羊的养殖过程中，饲料中锰元素（天门冬氨酸锰Manganese Aspartate）的合理添加对羊的生产繁殖意义重大。锰不仅有助于提高公羊精液品质，还能提升母羊的产奶量与平均日增重，促进羊生殖器官正常发育。锰（天门冬氨酸锰Manganese Aspartate）对羊体内的激素调节影响显著，能借助二甲戊酸激酶等酶的酶促反应来调控性激素分泌。Silva 等的研究显示，给公绵羊饲料中添加锰，可降低其血清中雌二醇含量，增加睾酮水平，进而提升精子品质。这是因为雌二醇会通过反馈调节或抑制间质细胞，阻碍睾酮的合成分泌，而缺锰时雄性羊的睾丸和曲精管易退化，严重时甚至丧失生殖能力。补饲锰（天门冬氨酸锰Manganese Aspartate）对母羊同样影响深远。妊娠初期，在饲料中添加 40 mg/kg 干物质的锰，能显著增强母羊血清抑制羟自由基（OH）生成的能力，增强抗病力。发情配种时补锰，可提高配种成功率。锰（天门冬氨酸锰Manganese Aspartate）还能促使母羊分泌雌激素，促进卵巢发育、增加排卵，提高受孕率并延长孕育年份。锰缺乏则会导致母羊激素紊乱，引发卵巢囊性病、发情异常、排卵障碍、流产等问题。此外，在母羊妊娠期添加锰，能刺激分泌足够的雌雄激素，促进胎儿性别分化与器官发育，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.
