Bamboo Rat Reproduction Technology
Bamboo rats are pregnant for about 60 days, a week before delivery, nipples prominent, reduced appetite, often not moving, eat enough to sleep. 1-2 days before birth, restless, with abdominal pain, appetite completely stopped, issued a "squeak, squeak" cry, hind legs bent like defecation, and scrawl to do nest. If the male and female are raised together, the female rat will drive out the male rat from the nest and the two sides will be torn apart. In severe cases, the male rat will be killed. When the mother's teat can squeeze out a small amount of white milk, it indicates that she will give birth within one day. When she is pregnant, the mother mouse discharges purple or pink amniotic fluid and contaminated blood, and the fetus heads out first, then the body. After the farrowing is completed, the mother bites off the umbilical cord, eats the placenta, and dehydrates the amniotic fluid from the offspring. The birth number of 1-2 births is usually 1-2, and the number of normal litters after the third birth is usually 3-5, and 5-7 are high-yield. For 3-5 babies, the production process takes about 3 hours. It's best not to take the cover plate to watch the mother's baby for a week. It's easy to scare her mother. The frightened mother is very easy to eat, and the feeding should be done gently.
1) Matching breeding: If there is a shortage of mother rats at the time of purchase, parents and males can be paired. Pairs of male and female rats must have different nests (indicated when they are born). This 1 male and 1 female pair is suitable for detailed breeding records. It is beneficial to maintain pure breeding, and breeding seeds are often used for this method.
2) Matching group breeding: a group consisting of 1 male and 2 females or 1 male and 3 females. However, most of the methods are dubbed 2 males and 4 females or 2 males and 6 females or 3 males and 12 females. Rats are allowed to be in the same nest. Male rats must not be allowed to have their own litter. They must also pay attention to the affinity between the male and female rats during the matching process. When the male and female co-educate for a week, there is still fighting or multiple estrus and no species. Explain that the combination of the mother and the difference in strength is not suitable for matching groups and should be regrouped.
3). Monogamy: The bamboo rat has a strong memory and is basically a monogamous system. Once paired or matched, it is very difficult to disassemble the regrouping group. Therefore, whether it is a pairing or matching group, it must be a small group. Make proper arrangements.
4) to prevent inbreeding: Where three generations of male and female rats with immediate genetic relationship are not suitable for breeding. Therefore, male and female rats in the same litter cannot be paired or matched directly. They must cross and collude with another litter to avoid inbreeding. In larger farms, different litters of pups are kept alone for one month after weaning, and then placed in large pools for breeding. The groupings are sold after the grouping. Therefore, all introduced breeders should pay attention to this issue.
5), breeding technology:
A, conventional mating method: maternal and maternal mothers from a small group of mixed maternity, allowing them to freely choose to mate and found pregnant pregnant mothers separated after the separate breeding. After the weaned mother had been weaned for 30-35 days, the dams were transferred to Dachi and other males and females for cohort rearing, or separated and fed separately with the original male rats. Good nutritional conditions, weaning time is exactly the time of maternal estrus, male and female cohorts will be able to match after 2-3 days, if found to be weaned mothers bite, and the feed is not lacking, it means that maternal premature estrus The mother must be isolated in time to allow the male to breed with him in time.
B. Blood Matching Method: This method is an effective method for shortening the breeding cycle and raising the maternal calving capacity. When males and females are housed in cages, the male and female must be separated during the farrowing period. After 12 hours of maturation, the mood has stabilized. When there is a search for male rats, you can perform "blood matching." The method is to put the female rat into the cage for 12 to 48 hours after farrowing, and compound it with two male rats separately. The two male rats must be raised together and close to each other when they are young. Otherwise, the mother and the mother will fight each other endlessly. The first mating can be performed 12-24 hours after childbirth, and the second one is mated 25-48 hours after childbirth. The time for each cage is 1 hour. After the breeding is completed, the maternal mice are returned to the farrowing litter. This repeated breeding can increase the litter size of the number of litters, only the implementation of "blood allocation", only one year before the possible birth of 5 tires, only the implementation of the compound, a litter size can reach 5 - 6 or more, but this method Not suitable for beginners to try.
