Breeding technology of rex rabbit
One of the most promising industrial projects to get rid of poverty and become rich. The key points of its cultivation technology are as follows:
First, choose good varieties. Rex rabbit is a kind of rabbit with both skin and meat. French or American rex rabbits with big body, capillary, soft, bright, smooth, white or cyan should be selected as excellent breeds.
Second, scientifically match the feed. Rex rabbits are herbivores, because all herbivores raised artificially can't meet the nutritional needs of rex rabbits, so in daily feeding, in addition to feeding some fresh feed in a planned way, it is necessary to equip them with full-price pellet feed according to a certain proportion. The advantages of complete pellet feed are: it is not frozen in winter and not moldy in summer. Rex rabbits love to eat and have comprehensive nutrition. Its formula is: bean cake or soybean meal 15%, corn 10%, bran 19%, straw or weed powder, fish meal, bone meal 1.5%, salt, growth promoter and rabbit additive/kloc-0.
Third, strictly control farming. At present, 70% of rex rabbits raised in China are imported from France or the United States. After breeding, due to the slow progress of purification breeding, the variety performance deteriorated and the fur quality decreased, which affected the economic benefits. Therefore, breeding must achieve five mismatches.
(1), immature male and female rabbits are not suitable.
(2) The General Department is not clear.
3. The sick are not worthy.
(4) Genetic instability.
(5), does not meet the requirements of directional breeding.
Fourth, prevent and control epidemics. Epidemic disease is the enemy of rex rabbit breeding, and the policy of "prevention first, combining prevention with control" should always be implemented. Should do:
(1), it is necessary to clean rabbit cages and huts frequently and timely, and do a good job in environmental sanitation. Disinfect once every 10 day in summer and once every 1 month in winter. Disinfecting drugs include Lysol, disinfectant, caustic soda, etc.
(2) Bath with medicinal liquid in spring, summer and autumn (trichlorfon 3%, mirex 0.0 1%, mirex 0.0 1%). In case of dermatosis, tinea pedis, tinea auricula and other diseases.
(3) epidemic prevention. Rabbits are injected with rabbit plague vaccine and Pasteurella vaccine 3-4 times a year to enhance the self-resistance of rex rabbits and improve and accelerate their growth and development.
Five, rex rabbit skin peeling processing. The slaughter time of rex rabbits should avoid molting period and summer. It is better to control slaughter and peeling in autumn, winter and spring. Slaughtering methods are:
(1), stick hitting method. It is to lift the hind legs of the rex rabbit weighing more than 2.5 kilograms, and then slam the medulla oblongata of the rex rabbit's ears with a wooden stick and kill it.
(2) Electroanesthesia. Electric anesthetic with voltage of 70 volts and current of 0.75 amperes was used to shock the ear roots of rex rabbits.
(3) Inflating method. 5- 10 ml air was injected into the ear vein of rex rabbit to make it die of blood embolism. After the rex rabbit was put to death, the rex rabbit's hind legs were tied with ropes, hung upside down on a post, and its forelimbs and tail were cut off. Then use scissors to pick it from the joint of the hind leg along the parallel line above the inner side of the leg, peel off the surrounding hair and turn it outwards. By pulling off the sleeves, one person covers his abdomen with his hands, and the other person pulls the whole rex rabbit skin into a tube, and then splits the scalp off at the ear root, which becomes the outer tubular skin of Mao Chao Lippi. After removing blood stains and other dirt, fresh test tube skin can be placed on the skin bracket with the head up and the tail down. Remove the fat and meat scraps left on the leather board, straighten the abdomen and back, straighten the fur, let it stretch naturally, fix the lower end of the leather board with clips or strings to prevent it from shrinking and curling, and then hang it in a ventilated and dry place to dry.
