How to raise fur animals well

1. Feeding during sexual organ development

At the autumnal equinox, the sexual organs of furry animals begin to recover. Therefore, from September 20 of each year, the breeding animals can be raised as breeding season. Taking into account some practical circumstances, large feed is still winter hair feed, but premix (some places called small feed) must be used breeding period. Feed in breeding period should focus on the comprehensive balance of various nutrients to promote the overall healthy development of animals.

2. Scientific control of physical conditions

From late November onwards, fur animals have been very fat, coupled with the cold weather, animal appetite began to decline. At this time, the proportion of raw materials such as oil and corn flour in the feed can be appropriately reduced, and a small amount of raw materials such as vegetables and bran can be supplemented to avoid starvation before breeding because of excessive obesity. In addition, before breeding, prenatal such special stage, for individual body condition is not suitable, must be adjusted separately. Pre-mating and prenatal body condition control during breeding is critical.

3. Check the situation when injecting vaccine

Animals should be vaccinated around New Year's Day every year. At this time farmers must pay attention to check the female animal's estrus. Depending on the time of vaccination, about 30% to 40% of female pubic hair has begun to change. In some warm places, the proportion of female animals estrus can reach 40% in farmers who are vaccinated around January 10.

4. Timely mating

Fox and raccoon are seasonal and persistent estrous animals. Once a year, the season of estrus lasts for a long time, but once the estrus ends, it can only wait for the next year to estrus again. Therefore, once the fox and raccoon are in estrus, they should start to put them in pairs when the pubic mound begins to retract and the color is dark red. Generally, once a day, they can be put in pairs 2 to 3 times in a row. Mink is seasonal, repetitive estrous animal. During the estrous season, there are generally 5 to 8 estrous cycles, and the estrous cycle is 7 days. It is suggested that farmers should adopt 1+1 breeding method on February 20 (coastal, northern, cold places, cold winter years should be postponed 7 days to 15 days).

5, timely division

After each of the above steps is done according to the requirements, about 35 to 40 days, the litters can be divided according to the individual size of the pups. The standard weight of fox and raccoon litter is more than 3 jin, female mink is 7 or 8 liang, male mink is about 1 jin.

6, enhance nutrition

After hormone implantation, nutrition should be enhanced, especially the balance of protein and amino acids. After one month, the feed list of winter fur period is changed. About 60 days after the hormone implantation, the female mink begins to skin, and the male mink can mature and take skin in more than 70 days.

7. Control feed quality

From procurement, processing to feed preservation and other aspects, there are strict quality awareness.

8. Strengthen epidemic prevention and environmental sanitation

When vaccinating, it is better to do it slowly than as required. Regularly clean up feces, stagnant water and dirt. Periodically disinfect.
