2, lack of protein protein can cause ovulation delay in the ovary puberty, empty period extended. Protein levels are too high and have negative effects on fertility. In addition, feeding high-protein diets to increase the level of ammonia in the rumen will have a toxic effect on the embryos and may have other adverse effects on fertility.
3, the main source of vitamins required for vitamin sheep body are three aspects: First, the intake from the diet, the second is the synthesis of various vitamins, and the third is the synthesis of vitamins rumen microorganisms. Causes of vitamin deficiency: First, the vitamins are lost due to the long storage time of the feed. The second is long-term house feeding or long-term stress in the sheep, so that the synthesis of vitamins reduced. (a) Vitamin A. Vitamin A is essential for the underdevelopment of animal epithelial cells, and if it is absent it can cause infertility to some extent. Mainly as follows: puberty, ewes delay in the puberty, eczema miscarriage or less production, new born blindness or ataxia lambs, fetal clothing, high incidence, placental keratinization degeneration, increased incidence of metritis, The ram's libido decreased, the testicles shrank, the number of spermatozoa in the delicate tubules decreased, and the ovarian function of the ewes decreased. (b) Beta-carotene. It was found that in the absence of β-carotene and adequate vitamin A can cause hepatic ketone levels decreased, delayed ovulation, reduced estrus intensity, increased incidence of ovarian cysts, delayed uterine involution, prolonged recovery of postpartum ovarian function, early embryonic death The rate rose. (c) Vitamin D. Vitamin D deficiency can cause estrus delay. (d) Vitamin E. Vitamin E and selenium are important antioxidants, but its mechanism of action in reproduction is still unknown. It has been reported that vitamin E deficiency can cause congenital malformations in lambs.
4, lack of minerals or unbalanced minerals lack or imbalance can cause sheep infertility. Calcium indirectly affects reproduction. Phosphorus participates in energy metabolism and the development of bones and milk production, and therefore has a close relationship with reproduction. The lack of selenium mainly causes a decrease in fertility. Iodine is involved in the synthesis of thyroxine, so it affects the reproduction of sheep through the synthesis of thyroxine.
Relationship between nutritional deficiencies and sheep reproductive disorders
1. Carbohydrates Carbohydrates are the main components of animal diets. If the energy level of the diet is high before and after oestrus, the ovulation rate can be increased, and there is no adverse effect on the survival of embryos during early pregnancy. However, if the ewes gain too much weight or consume too much energy, the interval between conceptions will be prolonged. In order to improve reproductive performance, postpartum ewes should be provided with higher energy to avoid excessive weight loss, but the intake of energy should be gradually increased, otherwise it will cause obesity.
