The method of improving masked palm civet's fecundity

Abstract: masked palm civet is a seasonal multi-cycle oestrus, which is the estrus season from mid-January to late July every year. Wild masked palm civet can only give birth to one child a year, 1-2 per birth, domesticated artificially, and can give birth to 2 births a year, 3-4 per fetus. Let's take a look at the ways to improve masked palm civet's fecundity.

Masked palm civet is a seasonal multi-cycle oestrus, which is the estrus season from mid-January to late July every year. The wild masked palm civet can only give birth to one child a year, 1-2 per fetus, domesticated artificially, and can give birth to 2 births a year, 3-4 each. Let's take a look at the ways to improve masked palm civet's fecundity.

Cultivate highly propagated populations

The main results are as follows: 1. In order to obtain a breeding herd with strong reproductive ability, it is necessary to make directional selection.

① female beaver: gentle temperament, high litter rate, no less than 3 per litter, neat and symmetrical nipple arrangement, strong lactation ability, good motherhood, no bad habit of eating baby beaver.

② male beaver: the growth speed is fast, the feed reward is high, the weight is 6kg-6.5kg, the male is strong, the double testicles are symmetrical, the size is moderate, the coat color requirement is grayish yellow, the head face black and white cross should be clear. In order to obtain a good population with stable and excellent characters, it can only be formed through directional cultivation and accumulation of 3-4 generations.

2. Mating: the female beaver is selected to mate with the most obvious signs of oestrus, the old mating is early, the little mating is late, and the middle mating is in the middle. Repetitive mating and double mating can be used in the female beaver's estrus. The same male beaver is used to mate twice successively, and double mating means that the female beaver uses two male beavers to mate with the female one after another during the same period of estrus. The interval between mating is about 20 hours.

Shorten production cycle

1. Engage in artificial breast-feeding to shorten the lactation period of the young beaver. Before May of each year, the first-born young beaver was taken out and placed in an incubator at the age of 7-10 days after birth, and then fed with milk. The initial temperature was 29 ℃ and decreased to 26 ℃ after 20 days of age. The formula of artificial milk is 25 grams of milk powder, 30 grams of malt milk, 10 grams of sugar, 1 tablet of calcium and 1 tablet of yeast, mixed with boiling water into 250ml, cooling to 40 ℃, adding compound vitamin B solution 3ml to 5ml, feeding in human milk bottle, 4 meals a day, and training young beavers to eat after 30 days of age. After 45 days of age, young beavers can eat well and are gradually weaned.

2. The mixed culture of male and female beavers makes the female beavers come into estrus earlier during the diestrus. Raising male and female beavers in the same cage (enclosure) can promote oestrus and mating of female cats. Or the non-estrus female beaver is close to or raised in the same cage with the non-estrus and mating female beaver, and through the influence of the oestrus and mating behavior of the non-estrus female beaver, stimulate the non-estrus female beaver to estrus and ovulate.

3. Drug treatment of anestrus female beaver after weaning. For female beavers that are not in estrus 15-20 days after weaning, sex hormones can be used to induce estrus. Diethylstilbestrol tablets are given 10 tablets at a time for 3 days. At the same time, the contents of trace element selenium and retinol E in food were appropriately increased to improve the sexual function of male and female civet.

Improve the survival rate of young beavers

1. The delivery of female beaver and the feeding and management of young beaver. After one month of pregnancy, the female beaver should be fed in the delivery room alone to prevent miscarriage or stillbirth caused by disturbance and fighting among the beavers. In order to ensure the safe delivery of the female beaver, the expected birth date should be calculated according to the mating date. A file should be set up for each beaver and recorded day by day. The due date is 58 days after the last meatball (vaginal suppository) was found in Dibu. More than 80% of female beavers give birth on this day. Be prepared to deliver labor. For young beavers with "fake death", after cleaning the mucus in their nose, they can do human-factory breathing, and the female beaver with "eating disease" should be stopped in time. When the female beaver is difficult to give birth, she is given midwifery or caesarean section. If there is massive bleeding in the birth canal, you should immediately block the vagina with skimmed cotton and inject vitamin K, 10 mg in time. The female beaver 1mi was given warm red sugar water within 2 days after delivery, and the feeding amount was increased after 3 days. Young beavers should pay attention to iron supplement within 7 days of age, with "iron-rich" intramuscular injection, the dose is 1 ml per animal.

2. Correct feeding and management is an important factor to improve the survival rate. Young beavers should be dewormed in time when they are 45 days old, and be fed with levamisole according to the prescribed dosage for 2 days, and at the same time, enough trace elements, vitamins, calcium, etc., to enhance their physique, improve their disease resistance, and begin to be vaccinated at the age of 60 days. the baby beaver must be vaccinated with measles vaccine, and then vaccinated with dog vaccination half a month later. At the same time, the young beaver was given a pill of traveling Angong Pill every day for 3 days, and the effect was very good. When the young beaver is sick or weak, it can be fed with Banlangen granule 4MUE for 5 days, 2 packs a day. After the baby beaver recovers, it will be fed with travel Angong pills, and the baby beaver can ride out the danger safely.
