Vitamin E, also known as tocopherol, enables the normal development of sexual cells to maintain reproductive function, plays an important role in preventing fat oxidation in feed, and participates in the body's normal metabolism and many biochemical processes.
Due to the special structure of mink diet, when the feed contains rancid fat, the content of unsaturated fatty acids is too high, or the supply of vitamin E is insufficient and the supply method is unreasonable, which often leads to the lack of vitamin E in blisters. So when there is a lack of vitamin E, how much will it affect the reproduction of leech?
According to the study, vitamin E deficiency in mink is mainly characterized by pathological changes of reproductive organs and disorders of reproductive function; male animals have low libido, smaller testicles, fine tube atrophy, semen production disorders, abnormal sperm morphology, and reduced numbers. Activity is weak, female animals are delayed in estrus, and mismatches increase. The most obvious manifestations are embryonic uptake, miscarriage or stillbirth, decreased number of births, poor maternality, and an increase in urgency and loss of normal fertility.
Case 1: In a market, 80% of public money in the breeding period cannot be used, there is no sexual desire, and the mother's esteem is not obvious (observe the vulva). Breeding fails. The reason for the analysis was the lack of vitamin E in the ration preparation ration. Although vitamin E capsules have also been added to the feed, they are not added in the same way. After they are dissolved in lukewarm water, they are rarely absorbed, causing vitamin E deficiency. In the second year, the same diet formula was used during the breeding preparation period. However, the vitamin E was added in different ways. Instead, it was heated and dissolved with vegetable oil, and was diluted and added to the feed. The results to the breeding period, 80% of the male libido is strong, the mother estrus estrus normal, and soon completed the breeding task.
Case 2: A miscarriage or abortion occurred during the pregnancy in one of the market. After farrowing, 70% of the mother-in-law have no milk, and she is hungry. She is snarled and crawls everywhere. The mother-in-law is disturbed and frequently goes out into the small room. She does not protect her baby in the nest, showing that her mother is not strong. In the market, taking the hairs around the breasts, and feeding breast milk tablets and other emergency prolactin measures, it has not seen any improvement. The youngsters have died one after another. Finally, the breeding of minks has failed. Comprehensive analysis of the reasons, it is understood that this market maternal vitamin E supplementation during pregnancy is based on 5 mg per day, and is added after the water-soluble. It can be concluded that the lack of vitamin E during pregnancy leads to fetalization and miscarriage. After delivery, the mother has no milk and motherhood is not strong. In the second year on the basis of the original diet, the amount of vitamin E added to the mother's lice during pregnancy increased to 12.5 milligrams per day, that is, human use of vitamin E capsules (100 milligrams), 8 capsules per jellyfish. , After the vegetable oil is melted, it is added to the feed, and it is evenly mixed and fed. As a result, mothers did not experience a miscarriage during pregnancy. After farrowing, 98% of mothers had sufficient lactation and good motherhood. The market is quiet and the mother-in-law eats food outside of the small room. She does not leave the room for the rest of the day to protect her.
In addition, vitamin E is used in the breeding of mink, and also has anti-oxidation, yellow bile fat prevention of blisters, treatment of blisters, tail hair removal, tail tip ulcers and other diseases. Special attention should be paid to the fact that vitamin E is a fat-soluble vitamin that needs to be heated and dissolved in oil and added to the feed.
