Four seasons breeding characteristics of rabbits

(A) The spring spring has a mild climate, abundant forage, strong libido in male rabbits, and a high fertility rate for mating females, which is a good season for meat rabbit breeding. Male rabbits had the highest ejaculation and sperm density in the spring, and the female rabbits had a estrus rate of 80% or more. The fertility rate of the mating period was 90%, and the average litter size was 7-8. Therefore, farmers must seize this favorable opportunity to do a good job of breeding. However, due to the rainy season in the spring of South China, the humidity is too high and the puppies are susceptible to disease. Therefore, we must do well in preventing moisture and preventing diseases during breeding. (B) summer summer hot climate, high temperature and humidity, meat rabbits loss of appetite, physical fitness is weak, sexual function is not strong, the rate of mating fetus is low, fewer litter size. In summer, the spermatozoa of male rabbits decreased in vigor, the density decreased, and the number of abnormal sperms increased. The female estrus rate is only 20% to 40%, the conception rate is 50% to 40%, the average litter size per litter is 3 to 5, and the survival rate is also very low. If the female rabbit is in good conditions in summer and shade and heatstroke prevention conditions, and the temperature is lower than 32°C, breeding can still be arranged appropriately. (3) In autumn, the climate in autumn is mild, the feed is adequate and the nutrition is rich. The physique of the male and female rabbits begins to recover, the libido gradually becomes stronger, and the female rabbit has a higher conception rate and a higher number of litters, which is a good season for breeding rabbits. From September to November, male rabbits showed a strong libido and increased sperm vitality. The female estrus rate is about 80%, the mating rate is about 65%, and the average litter size is 6-7. Autumn is the fluffing season for meat rabbits, which consumes large amounts of nutrients and has an impact on breeding breeding. However, strengthening feeding and management can be avoided. Male rabbits may experience temporary infertility after summer leisure, so the first breeding must be compounded. (D) winter and winter temperatures are low, lack of green feed, nutritional levels decline, breeder thin and thin, female estrus is not normal, the rate of mating fetus is low, so if the rabbit does not have a thermal insulation device is very easy to freeze to death. Male rabbits generally do not have strong libido during the months from December to the following year, but they are proficient in vitality and density. Female estrus rate of 60% to 70%, mating fertility rate of 50% to 60%, average litter size 6-7. However, if there are rich feeds in winter and there are good conditions for keeping warm, good reproductive effects can still be obtained.
