Several Trace Elements Affecting Reproductive Performance in Wild Boar Farming

1. Vitamin E

Vitamin E, also known as tocopherol, is closely related to animal reproductive performance and has effects such as promoting gonad and ovary development, facilitating conception, and preventing miscarriage. VE deficiency will cause reproductive dysfunction, failure to come into estrus or delayed estrus, infertility, miscarriage, stillbirth, and even loss of reproductive capacity. In addition, VE is also the material basis of humoral immunity, with effects of enhancing antibody levels, improving the body's resistance to disease, and strengthening stress resistance.

2. β-Carotene

β-Carotene is the precursor of vitamin A. Follicular development requires high concentrations of vitamin A. Vitamin A can hardly pass through the barrier between the blood and the follicular membrane to enter the follicle, while β-carotene can pass through the follicular membrane to enter the follicle and be converted into vitamin A, regulating reproductive activity. VA also has the effect of protecting the integrity and completeness of epithelial tissues, is an important material basis of mucosal immunity, and has a clear impact on the development of reproductive organs.

3. Methionine

Methionine must not be deficient in wild boar diets. The main role of methionine is to promote follicular development and ovulation.

4. Vitamin C

Vitamin C, also known as ascorbic acid, participates in redox reactions in the body, maintains the integrity of the intercellular substance of cells (such as eggs), and makes eggs robust. VC deficiency can also cause scurvy, anemia, and reduced resistance.
