Rex rabbits are also called rabbits and velvet rabbits. Because its fur is similar to the otters, it was named Rex Rabbit. It is a rare skin rabbit species. First, Breeding: Rex rabbits can usually mate with 5 to 6 months of age. In breeding, we must choose the same color of the rabbit to mating, at the same time require that there can be no relatives within three generations to avoid inbreeding. Rex rabbits usually breed four times a year. Matching time The first child in late March, the second child in mid-June, the third child in mid-September, and the fourth child in the middle of the 12th is appropriate. The number of days of pregnancy is related to the number of embryos, which is generally 30-31 days. The period of inbreeding of rabbits is 2-3 days, and there is a phenomenon of title grass. Practice has proved that the earliest niche grass to make nests, the better the motherhood, pull hair is another feature of Rex rabbits labor, 2-4 hours can be litter. If a litter box with a short-cut straw is placed 1-2 days before delivery, the female rabbit that does not jump into the nest in the table box will generally not give birth in the table box. In the winter, this kind of female rabbit must pay attention to observation, otherwise the puppies will be frozen and die. Once the puppies are found outside the box, they must be returned to the box. For females whose genital swelling is more than 31 days after pregnancy, 5 units of synthetic oxytocin can be induced by intramuscular injection. In most cases, the female rabbit automatically jumps into the table box to give birth and to suckle the rabbit. Second, feeding and management: dietary standards and compound feed formulations due to the large variety of rabbits feed, the rabbit dietary standards and the proportion of compound feed are also different, under normal circumstances, rabbits daily supply of green feed 800-1000 grams, Compound feed 100-250 grams. Formulated feeds are as follows: Adult rabbit: corn 10%, bean cake 1%, barley 20%, bone meal 1.5%, wheat husk 40%, salt 0.5%, rice bran 10%, additives and auxin 1%, digestive energy 2911 Card/kg, digestible crude protein 126 g/kg. Young rabbits: 7% corn, 20% soybean cake, 17% barley, 3% fishmeal, 40% wheat, 0.5% salt, 1% bone meal, 1.5% auxin and additives, digestive energy 2939 kcal/kg, digestible Crude protein 148 g/kg. In terms of feeding, green feed is the main source in summer and autumn, and hay and succulent feed are the main products in winter and early spring. Don't come too suddenly when changing the feed. The newly-changed feed should gradually increase. If the change is too fast, it may cause food loss or food refusal. The green feed is fed three times a day. It is required to feed early in the morning, feed less at noon, and feed at night. The amount of night meal should account for more than 50% of the daily amount. Green materials should pay attention to species diversity, do not feed a single species for a long period of time, in order to increase palatability, the supply of winter green materials is difficult, and high quality hay can be added. Nursing mother rabbits can not be interrupted, it is important to take care of. China Agricultural Network Editor
