Breeding techniques of Rex Rabbit and how to build Rabbit House

The main points of breeding techniques of Rex rabbit are as follows:

First, select excellent varieties. Rex rabbit is a kind of flesh-and-skin rabbit. French or American Rex rabbit with large size, fine hair, soft, bright, smooth feel, white or cyan color should be selected as an excellent breed.

Second, scientific collocation of feed. Rex rabbit is a herbivore, because all herbivores in artificial breeding can not 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 be equipped with full-price pellet feed according to a certain proportion. The advantages of full-price pellet feed are: it is not cold in winter, not moldy in summer, Rex rabbit likes to eat, nutrition is comprehensive. The formula is: soybean cake or soybean meal 15%, corn 10%, wheat bran 19%, straw or weed meal 3%, fish meal 3%, bone meal 1.5%, salt 0.5%, growth promoting hormone and rabbit additive 1%.

Third, the breeding should be strictly controlled. At present, 70% of the Rex rabbits raised in China are introduced from France or the United States. after breeding, due to the slow process of purification and breeding, the performance of the variety is degraded, the fur quality is reduced, and the economic benefit is affected. Therefore, the five unmatched must be achieved when mating.

(1) the male and female rabbits are not worthy of age.

(2) the general system is not clear and unworthy.

(3) those who are sick are not worthy of it.

(4) hereditary unstable mismatch.

(5) those that do not meet the requirements of directional breeding do not match.

Fourth, prevention and control of epidemic diseases. Epidemic disease is the great enemy in Rex rabbit breeding, and the policy of "prevention first and combination of prevention and control" should always be carried out. This should be done:

(1) it is necessary to clean rabbit cages and rabbit houses in time and do a good job in environmental hygiene. Sterilize once every 10 days in summer and once a month in winter. Disinfection drugs are: Lysu water, disinfectant, caustic soda and so on.

(2) use a potion in spring, summer and autumn (3% of trichlorfon, 0.01% of trichlorfon, 0.01% of trimethoprim) and one bath each. To prevent skin diseases, feet, tinea and other diseases.

(3) epidemic prevention. Rabbits were injected with rabbit plague vaccine and Pasteurella multocida vaccine 4 times a year to enhance the resistance of Rex rabbits and to improve and accelerate the growth and development of Rex rabbits.

Fifth, the stripping processing of Rex rabbit skin. The killing time of Rex rabbits should avoid molting and summer. It is better to control slaughtering and peeling in autumn, winter and spring. The methods of slaughter are:

(1) stick hitting method. It is to lift the hind legs of the Rex rabbit weighing more than 2.5 kg, and then hit the medulla oblongata at the root of the two ears with a wooden stick, causing it to die.

(2) Electric anesthesia. An electric numbing device with a voltage of 70 volts and a current of 0.75 amperes was electrocuted at the ear root of the Rex rabbit.

(3) ventilating method. 10ml of air was injected into the venous tube of the Rex rabbit's ear and the blood was embolized to death. After the Rex rabbit was killed, the hind legs of the rex rabbit were tied up with a rope, hung upside down on the post to amputate the forelegs and tails, then use scissors from the joints of the hind legs, follow the parallel lines above the medial vagina of the legs, peel and flip the fur outward, use the method of withdrawing the condom, one person protects the abdominal back with two hands, and one person pulls down the whole Rex rabbit skin in the shape of a tube, cut off the scalp to the ear root and cut off the scalp to become the tube skin facing Li Li outward. Fresh tube skin in the removal of blood stains and other dirt, according to the original head up, tail down on the leather support. Remove the fat and meat crumbs left on the leather plate, straighten the abdomen and back, straighten the fur, and let it stretch naturally. The lower end of the skin is fixed with a clip or string to prevent it from retraction, and then hang it in a ventilated and dry place to dry.
