Fifth, the recovery period of male and female animals;
Sixth, the juvenile growth period;
Seven, winter wool growth period.
Because all kinds of foxes, minks and raccoons have different estrus periods, and there are mating, pregnancy, breastfeeding and larval growth at the same time. During this period, the feeding managers should pay special labor, carefully feed, and scientifically feed in order to have good results. The main points of different periods are as follows:
First, the preparation breeding period:
There are three main technologies to master:
L, in165438+1October, we will carefully check the herds that are finally ready for breeding, and resolutely eliminate some foxes that are not good at molting, not big enough, not strong enough in development, not good in coat color, not good in milk, not strong in protecting their young, and have a record of eating young and self-biting.
2. Feed proportion: (summary of practical experience)
Silver black fox-the breeding preparation period is 65438+February 1 to February next year 10.
Blue fox —— The breeding preparation period is 65438+February 1 to March 15 of the following year.
This period is a period of adjusting physical condition.
Average number of meals given to the population:
Blue fox: 65438+600g at the beginning of February, and decreased to 400g at the end of February.
Silver fox: 65438+500g at the beginning of February and 350g at the end of February.
Special attention: during this period, breeders should insist on increasing lean fox feed and reducing fat fox feed without changing the average diet, and can't engage in equalitarianism! When checking the population, the female livestock population should reach the same standard of fat and thin.
Proportion of various substances in feed: (weight ratio) calculated by dry feed.
Fish, meat, grains and vegetables
52% 30% 10% 8%
In addition, water accounting for 25.2% of the total weight of dry feed was added.
Add special feed during this period:
Each fox is fed 6 grams of green onion, 8 grams of yeast, 3 grams of feather powder and 0.5 grams of salt every day.
Feed them one by one every Monday, Wednesday and Friday: cod liver oil 1500 international unit and vitamin E30 mg.
Feed them one by one every Tuesday, Thursday and Saturday: vitamin B 1 30 30mg, vitamin B2 30mg. Under the premise of the same proportion, reduce seed sales and adjust physical condition. +65438 in February, from 600g at the beginning of the month to 400g at the end of the month, and it will be reduced once every 10 day. Sudden reduction is strictly prohibited.
January:
The diet of each blue fox was reduced from 400g at the beginning of the month to 300g at the end of the month. (Note: The deceleration depends on the weather temperature and the species status of technicians. ) The diet of Silver Black Fox decreased from 350g at the beginning of the month to 250g at the end of the month.
February:
The food intake of each blue fox increased from 300 grams at the beginning of the month to 350 grams at the end of the month (350 grams on average in the whole month).
The black fox keeps a diet of 300 grams before giving birth.
March:
The average food intake of each blue fox is 350 grams, which basically remains unchanged throughout the month.
3, physical condition control technology:
The fox's physical condition refers to the general name of the fox's physical health. Physical condition is closely related to its reproductive ability, and only when it is suitable can it have a high level of reproductive performance. Rest state control is to adjust the fox's physical state to an ideal level on the premise of satisfying nutrition and ensuring health, so as to improve its reproductive ability.
Male fox is overweight: it will cause decreased sexual desire, poor semen quality, decreased mating ability and frequency, etc.
The mother fox is overweight: too much fat accumulates around the egg, which affects the normal development of the egg and delays estrus. At the same time, fat oppresses the fallopian tube, hinders the combination of sperm and eggs, and affects the pregnancy rate. Excessive fat accumulation around the uterine body will increase the embryo absorption rate during pregnancy, and in the late pregnancy, it will cause uneven fetal development and different sizes. Obese female foxes can also cause dystocia, postpartum hypogalactia and other diseases.
The female fox is too thin: it also affects normal estrus, mating and pregnancy. The mother fox is too thin during pregnancy, which will cause pregnancy interruption.
