錳元素（抗壞血酸錳Manganese Ascorbate）：動(dòng)物生殖與生長的關(guān)鍵調(diào)節(jié)者

錳（抗壞血酸錳Manganese Ascorbate）是維持畜禽正常生殖機(jī)能的必需元素，其在體內(nèi)含量失衡，無論是缺乏還是過量，均會(huì)擾亂生殖機(jī)能，嚴(yán)重時(shí)可致使雄性不育、雌性不孕。不過，在哺乳動(dòng)物中，錳缺乏的情況相對少見。王一冰等人在產(chǎn)蛋高峰期的黃羽肉種雞飼料里添加 90 - 120 mg/kg 的錳，顯著降低了胚胎早期死亡率。另有研究表明，飼糧中添加錳（抗壞血酸錳Manganese Ascorbate）會(huì)對 3 - 4 月齡獺兔的脂肪沉積和脂肪組織脂質(zhì)代謝產(chǎn)生影響。當(dāng)錳添加水平為 20 mg/kg 時(shí)，能有效促進(jìn)脂肪組織氧化分解，抑制其合成，降低體脂肪沉積率。王賀飛等發(fā)現(xiàn)，給產(chǎn)蛋期種鵝飼糧中添加適宜水平的錳，可提升繁殖性能、蛋殼厚度、蛋殼強(qiáng)度、血清總抗氧化能力和促卵泡素含量，同時(shí)降低血清丙二醛含量，建議產(chǎn)蛋期種鵝飼糧錳添加水平為 24.27 - 32.91 mg/kg（飼糧中錳含量為 60.67 - 69.31 mg/kg ）。此外，飼糧中添加 100 mg/kg 的錳，能提高雄性水貂生產(chǎn)性能，增加血清蛋白含量，提升氮代謝相關(guān)酶活性，且對脾無損害。錳元素（抗壞血酸錳Manganese Ascorbate）在動(dòng)物生長發(fā)育進(jìn)程中扮演著舉足輕重的角色，對保障動(dòng)物健康與生產(chǎn)性能意義重大。

Manganese (Manganese ascorbate): a key regulator of animal reproduction and growth

Manganese (manganese ascorbate) is an essential element for maintaining the normal reproductive function of livestock and poultry, and its content in the body is unbalanced, whether it is lack or excess, it will disrupt reproductive function, and in severe cases, it can cause male infertility and female infertility. However, in mammals, manganese deficiency is relatively rare. Wang Yibing et al. added 90 to 120 mg/kg of manganese to the feed of yellow-feathered broiler breeders at the peak of egg production, which significantly reduced the early embryonic mortality rate. Other studies have shown that the addition of manganese (Manganese ascorbate) to the diet has an effect on fat deposition and lipid metabolism in adipose tissue in 3-4 month old rex rabbits. When the level of manganese addition is 20 mg/kg, it can effectively promote the oxidative decomposition of adipose tissue, inhibit its synthesis, and reduce the rate of body fat deposition. Wang Hefei et al. found that adding an appropriate level of manganese to the diet of breeding geese during the laying period could improve reproductive performance, eggshell thickness, eggshell strength, serum total antioxidant capacity and follicle-stimulating hormone content, and at the same time reduce the content of serum malondialdehyde, and recommended that the manganese addition level of the diet of breeding geese during the laying period was 24.27 - 32.91 mg/kg (the manganese content in the diet was 60.67 - 69.31 mg/kg). In addition, the addition of 100 mg/kg of manganese to the diet could improve the production performance of male mink, increase serum protein content, and increase the activity of nitrogen metabolism-related enzymes, without harming the spleen. Manganese (Manganese ascorbate) plays a pivotal role in the growth and development of animals, and is of great significance to ensure animal health and performance.
