The comprehensive technical measures for improving the fertility of musk rat are as follows:
1. Feeding diversity and ensuring nutritional requirements The dietary standards of muskrats are not significantly different in each feeding period, but the nutritional requirements in different periods are different. To ensure their nutritional needs, the necessary supplementary feeds should be adjusted and added according to the characteristics of each period. . In addition, a small amount of animal husbandry can be fed during the breeding season to promote reproductive function.
2. Early water supply and ground exchange are not only necessary for the life of musk rat, but also necessary for breeding. Practice has shown that in the early spring of March, the water supply to the May water supply can be given 1 month in advance and the number of births is also greatly increased. The early water supply can produce 3-4 tires per year, while the late water supply has fewer births. For example, measures to enhance insulation and temperature increase, such as solar plastic greenhouses, can produce 5 tires per year.
3, to strengthen the winter insulation and heat preservation in summer is the important measures to ensure that the musk rat over the winter, improve physical fitness, a direct impact on reproductive ability. Because of the poor insulation during the winter, some of the body will be extremely thin after winter and even have a tail. Toads are frozen and it is very difficult to return to normal conditions after spring, and it is impossible to invest in breeding. Summer heatstroke is also very important, otherwise stuffy rats will be hot and stuffy, will inhibit the breeder rats, reduce sexual desire or estrus delay, thus affecting their reproduction.
4, strengthen management, pay attention to hygiene Muskrat is a very loving clean animal, although self-cleaning ability, but the environment created by man-made dirty, musk rat itself is difficult to adapt. When the water in the bath or pool is not clean, it will feel uneasy and clean up the cleanliness of the nest to have a certain influence on its reproduction. In addition, eating the remaining unclean green feed or damp valerian in the summer, if not cleaned and replaced promptly, will often cause rot and mildew, resulting in high fever, easy to suffocate the pups or cause paralysis, and reduce the survival rate of the pups.
5, strengthen management, keep the environment quiet
6, self-employed one-mother combination
7. Discussing one male and female cohabitation, breeding or artificial insemination
8, to explore the impact of constant temperature bath water supply on reproduction at room temperature
9. Selecting and matching the seeds to improve the physique of the species
10. Strengthen rearing of young pigs and young rats
11, feeding and management seven elements
