Rex rabbit, also known as Lex rabbit, is a typical skin and rabbit. Rex Rabbit has more than 20 kinds of coats such as black, white, coffee, yellowish brown, sky blue, and silver gray. Its hair is short and thick, and its color is bright, bright, and free from falling. The heat insulation is uniform and uniform, and it is very similar to the bristles of furs. It is very popular in the domestic and international fur market.
Rabbit meat is high in protein, low in fat, delicious in taste, easy to digest, and often eaten with beauty, anti-aging, and fitness enhancement. It is a rare health food.
At the same time, Rex Rabbit is a herbivorous animal, fast breeding, short feeding cycle, as long as careful feeding, breeding 6--7 months a year, 30 rabbits can be bred, such as the family to raise the scale, can obtain higher economic benefits.
(I) Feeding Wild weeds and leaves can be fed, but pesticides should be prevented from contamination. Leguminous pasture and crop stalks such as soybean stalks, peanut stalks, and sweet potato pods can all be used as roughage to feed rabbits. Under normal circumstances, adult rabbits daily green feed 800 - 1000 grams, 100 - 150 grams of concentrate feed. The formula for concentrate feed is: corn 40%, bran 20%, bean cake 20%, rice bran 5%, barley or sorghum 5%, fishmeal continent, bone meal gauge, salt 1%, auxin additive 1%.
(II) Feeding management Rabbits have higher feeding and management conditions than ordinary rabbits. It is afraid of hot, humid, like clean, dry and cool. Need to be kept in a rabbit house. The rabbit house should be airy and light. The temperature is controlled at 10-25°C; it is cleaned and disinfected once a day, and the utensils and drinking equipment are disinfected twice a week. Male and female rabbits and puppies, because of their different physiological characteristics, must be treated differently in feeding and management.
1, male rabbits. Male rabbits should supplement protein feed and vitamins A and E (carrots) during the breeding period. If male rabbits are bred twice a day, the feed should be increased by 25%. Each male rabbit should be fixed with 2-5 female rabbits. The male rabbit has a service life of 2-3 years. Match the same color when mating, and it is forbidden to match different color rabbits or match other rabbits.
2, female rabbits. Pregnant female rabbits (29 to 31 days during pregnancy) should be kept quiet during pregnancy. Do not catch them casually and do not feed them. Three days before childbirth, properly reduce the amount of concentrate feed. Prepare prenatal preparations, sterilize breeding litters, and then spread soft and short straws. At this time, you should prepare cold water and put in a small amount of salt and sugar. Rice soup is also available. Such as postpartum lack of milk, you can feed 2 tablets of lactation, and feed 2 to 3 days; you can also add brown sugar and hot lard in the feed.
3, puppies. It is important to prevent all harmful animals from entering the rabbit house and prevent the puppies from running outside to avoid overheating and overheating. After 18 days, the young rabbits should be trained to feed on foods that are easy to digest and nutritious. When they are 30-45 days old, they should be weaned in stages. When the pups were 45 days old, they were injected with vaccines against P. cruzi and Pasteurella.
(3) Breeding Breeding Rex rabbits have no obvious seasonality, so breeding can be done throughout the year, but the rate of conception in spring is the highest. Male rabbits must be mated at 5 months of age and 2.25 kg in weight. Rabbits need a cage for rabbits. When mating, place the female rabbit in a rabbit cage and return it to its original position after completion. Summer breeding should be done before 7am and after 8pm, and during the winter before 10am and before 4pm. The farmer breeds rabbits, protects them from heat in the summer, protects against the cold in winter, and builds breeding nests for the female rabbits to reproduce naturally.
(d) Disease Prevention Rex Rabbit common diseases include coccidiosis, rhinitis, and athlete's foot. Pay attention to moisture, add a certain amount of garlic to the feed. Round onions, leeks, etc., and regular quantitative feeding of flufenidoxime and sulfamethazine. If there is a sick rabbit to isolate in time, the main injection of penicillin, with sulfonamides, twice daily. Ankle sputum treatment with a mixture of liquid or dipterex and diesel. Apply the affected area and receive good results. However, it should be noted that the affected area should be scrubbed with potassium permanganate solution before application.
Plastic film coverage is a new technology for increasing peanut production. According to the experiment, the yield increased by about 20% compared to open field cultivation, and up to 40%. The technical points are:
First, choose good breeds. Selection of improved varieties should be based on fertility. The medium-fertility land with deep soil layer, loose texture, and strong water retention and fertility guarantees the selection of high-yield varieties with medium-maturing fruits and large erection potential, such as Luhua No. 11 and Haihua No. 1; water and fertilizer conditions Poorly thin land should use high grade products such as Baisha 1016.
Second, apply the base fertilizer, fine soil preparation. The conical root system of peanuts requires soil conditions with deep soil, loose texture, strong permeability, and high fertility. Therefore, under the premise of winter and spring deep turning, Mushi rotted organic fertilizer 3000-4000 kg, ammonium bicarbonate 40 kg, phosphate fertilizer 50 kg, potassium fertilizer 27 kg, and then shallow ploughing, smashing and building rake, 畦 60 - 80 cm, 10-15 cm in height and 20-25 cm in width. If there is a lack of lyrical moisture, it is necessary to irrigate the soil before planting, so that the soil moisture content can reach 15%-16%.
Third, timely sowing and filming. The appropriate sowing time for the peanut-mulched peanuts is the criterion that the frost break period after sowing has already passed. It is unfavorable for high yield if it is too early or too late. Peanuts must be sun-dried for 2-3 days before sowing to promote germination and germination. Before the planting, we must spray herbicides such as pullers to prevent weeds. Equally spaced rows of 8000-10000 holes, 2-3 kernels per hole.
There are two forms of coverage: pre- and post-broadcasting. Each has its own advantages and disadvantages. At present, it mainly covers post-broadcast coverage. In the case of poor soil moisture conditions, it can also be covered first. After the film is covered, the soil shall be used to compress the four sides, and a strip of earth shall be pressed horizontally every 3 meters to prevent the wind from uncovering the film to ensure the improvement of the ground temperature.
Fourth, timely rupture of membranes, clearing seedlings. Peanut-coated peanuts emerged in about 10 days, and they were first sown with peanuts. When the seedlings were just unearthed, a triangular knife was cut on the membrane with a knife to help the seedlings to produce a film to prevent burning at high temperatures. When the peanuts are seedlings, the roots of the seedlings are exhaled by hand, leaving the two cotyledons exposed outside the membrane and clearing the seedlings to reduce the growth of weeds and aphids in the rhizosphere. Twenty days after the clearing, the earth was timely and the seed setting rate was improved.
Fifth, chemical regulation, nurturing strong seedlings. Chemical regulation is a high-yielding cultivation technique for peanut covered film. For those blocks that are prematurely closed and overly prosperous, spraying with 1000-1500 times more fluid than BJ (B9) in late July can effectively shorten the internodes, increase lateral branches, and increase fruit filling rate. Generally, the yield increases by 15%- 25%; For fertility deficiency and premature failure fields, 0.2%-0.3% potassium dihydrogen phosphate or 0.2% superphosphate calcium clarifier should be sprayed, plus 1% urea mixed spray.
Six, drought relief, disease prevention and pest control. In the whole breeding period of peanuts, it is necessary to prevent drought and pay attention to drainage. When the soil moisture content is lower than 10%, it is necessary to water in time; when the rainy season comes, dig a field trench and clear the drainage ditch to ensure smooth water flow and prevent field rot. Peanut pests and diseases mainly include aphids, cockroaches, leaf roller moths, leaf spot diseases, stalk rot, root rot, bacterial wilt and ferret. Aphid control with 105 times imidacloprid 2000 times spray, can be used to treat red spider mites; wolfberry can be used in the flowering period of 50% phoxim per acre 2000.
