How to raise rex rabbits

Young rabbits were fed a small amount of digestible tender grass and leaves on 16. Full-price feed should be put in 22 days, and less feed should be added. Young rabbits can be weaned when they are 28-42 days old and weigh 750g. Take intermittent weaning, feed once every other day, and stop breastfeeding after the second feeding. After weaning, young rex rabbits are kept in cages according to their weight and sex. Pay attention to heatstroke prevention and keep the rabbit house dry and clean. At the same time, after weaning, we should inject immune vaccine and take anticoccidial drugs to prevent coccidiosis.

Second, feed well.

The normal microbial flora has not been formed in the digestive tract of newly weaned rabbits, which is prone to digestive tract diseases. Probiotics should be supplemented after weaning to help them form a normal microbial community as soon as possible. The newly weaned rabbits should be fed a complete compound feed with small volume, easy digestion, high energy and protein content. You can't suddenly change the type of feed and increase the amount of feed, but you should be less diligent to avoid feeding too much at a time, causing indigestion and diarrhea.

Third, keep the rabbit house clean.

Rabbit huts should be set in sunny, leeward and dry places. Clean the rabbit house every day, remove impurities in the tank in time, and check the drinking water tank to ensure the clean water quality. The rest of the forage should be replaced in time. High temperature, high humidity and low temperature and low humidity are not good for rabbits. The general temperature is 15-25℃ and the relative humidity is about 60%.

Fourth, strictly control disease prevention and control.

Young rabbits should be immunized regularly. Young rabbits were injected with Escherichia coli vaccine at the age of 20-28 days, then injected with Welch vaccine, Fusobacterium vaccine, Pasteurella multocida vaccine and Borrelia vaccine every 5 days or so, and injected with rabbit plague vaccine at the age of 45 days or so. Coccidiosis is also one of the main diseases of young rabbits, so it is generally necessary to feed anticoccidial drugs, such as adding some onions and garlic to the feed, or adding about 0.3 grams of oxytetracycline and sulfonamides to the feed.

How to raise rex rabbits in winter

With the coming of winter, the weather is getting colder and colder, and many rabbit farmers begin to worry about how to raise rex rabbits in winter.

Based on years of rabbit breeding experience, the author introduces several key techniques for raising rex rabbits in winter, hoping to help farmers.

The key to the integration of breeding rabbits is to have an excellent breeding rabbit group, and to keep young female rabbits with strong reproductive ability and rapid growth of offspring and young male rabbits with strong reproductive ability, strong sexual desire and strong mating ability and good performance of offspring as seeds.

Eliminate female rabbits with weak constitution and low birth rate and male rabbits with low sexual desire and poor mating ability.

Young rabbits with good performance are reserved for seed use, and the male-female ratio is at least 1∶8. In the rabbit group with less than 8 female rabbits, there must be at least 2 male rabbits, and the male-female ratio should reach 1∶4.

Cold and warm. The external environment temperature is low in winter. The first task of rex rabbit management is to keep warm and cold in the rabbit house.

On the premise of not affecting ventilation, plastic sheets should be nailed to the windows of the rabbit house, and door curtains should be hung in the indoor rabbit house.

Conditional rabbit farms can be equipped with heating or coal fire for heating; Most people in northern rural areas have no heating conditions and only use outdoor courtyards to raise rabbits. If rex rabbits are raised in iron cages outdoors, it is not conducive to the growth and development of rex rabbits, and it is difficult to breed in winter.

According to the author's years of rabbit breeding practice, a simple rabbit nest can be built with bricks, sand ashes and cement boards, and a calving room with a length of 35 cm, a width of 35 cm and a height of 30 cm can be built next to the mother rabbit nest.

Before the mother rabbit gives birth, add enough crushed wheat straw and let the mother rabbit make a nest. The mat should be dry, soft and warm, and made into a shallow bowl-shaped bottom with a low middle and high sides. In winter, an arched plastic film shed should be buckled outside the rabbit's nest. The height of the shed is suitable for people to move in the arched shed. Cover the plastic film with grass felt at night, and hang a cotton curtain at the entrance. In this way, rex rabbits can do it without coal fire.

The feed should be adjusted. It is cold in winter and consumes a lot of heat energy. Rex rabbits need more energy to maintain than other seasons and lack green feed. Therefore, it is necessary to adjust the feed formula of rex rabbits in winter, and the digestibility per kilogram of feed is higher than that in other seasons 100-200 calories. We should increase the proportion of feed corn in the formula, improve the digestibility of feed and increase the intake, which is 20%-30% higher than usual.

Coarse feed such as peanut seedlings, bean stalks and sweet potato seedlings. Respectively crushed, and then mixed with corn, peanut cake, wheat bran, bone meal, salt and other raw materials to prepare a mixed feed for rabbits.

Do a good job of feeding in winter. In winter, the temperature drops, pathogenic microorganisms are inactive, infectious pathogenic microorganisms are few, rabbit diseases are few, and the survival rate of young rabbits is high. As long as a constant temperature environment is created for rex rabbits, it is completely possible to breed in winter and raise them in winter.

Although estrus is not obvious, the female rabbit can estrus and ovulate normally after all. Therefore, we should seize the opportunity to breed the mother rabbit and arrange the rex rabbit to breed at noon when the sun is shining.

In order to improve the conception rate, the breeding method can be repeated breeding or doubled breeding.

In addition, after mating 12 days, the mother rabbit should be touched in time. The way to touch the fetus is to hold the ear and collar of the mother rabbit with the left hand, fix the mother rabbit on a flat or desktop, make the rabbit head face the mother rabbit's chest, and the right hand is inverted, and gently touch it from back to front. The embryo is spherical and elastic, and the dung ball is hard and inelastic.

Empty pregnant female rabbits should be replenished in time.

In winter, the artificial supplementary illumination time is short, the temperature is low, and the natural illumination time is only 9 hours, which is not conducive to the secretion of reproductive hormones in female rabbits, resulting in the decrease of reproductive hormone secretion in female rabbits, the weakening of ovarian activity function in female rabbits, and the increase of estrus and infertility in female rabbits. In order to improve the reproductive performance of female rabbits, artificial supplementary illumination should be provided, and the daily illumination time should reach 14- 16 hours.

Turn on the lights at 6:00-7:30 in the morning and 5:00-8:30 in the evening every day, and fill the light manually to make up for the lack of light.

The rabbit house should be clean. In winter, special attention should be paid to the environmental sanitation of the rabbit house, and the rabbit house should be disinfected regularly.

Disinfection should be carried out by two or more disinfectants in turn to prevent drug resistance; The rabbit house should be cleaned frequently, and the feces should be removed every day to prevent the accumulation of feces and urine.

In addition, disinfection should be careful and the rabbit house should be kept dry. In order to keep warm, the rabbit house is more closed in winter, but the ventilation is not good, and harmful gases such as ammonia, hydrogen sulfide and sulfur dioxide increase, which is easy to induce conjunctivitis and rhinitis in rex rabbits. Therefore, in the sunny noon, it is necessary to open the doors and windows to exhaust the polluted air in the rabbit house.

Epidemic prevention in winter, on the basis of preventing rabbit plague, Pasteurella, Bordetella and other infectious diseases, further do a good job in the prevention and treatment of common diseases such as colds and scabies.

Focus on the following three points:

First, in the use of vaccines, we should grasp the principle of using a single vaccine as much as possible, and replace the triple vaccine with two vaccines;

Second, rex rabbits are susceptible to mites in winter, and can be regularly fed with avermectin of two thousandths;

Third, when the temperature in the small ring of the rabbit house is above 65438 00℃, anticoccidial drugs should be added to the feed of rex rabbits, and two or more drugs such as chlorpheniramine and diclazuril should be used alternately to prevent coccidiosis.

How Rex Rabbit Adapts to Market Changes

In the early 1990s, the market price of rex rabbit skin remained relatively stable. In the late 1990s, influenced by market price factors, rex rabbit breeding industry developed rapidly, with two ups and downs from 1997 to 200 1 five years. But it didn't last long. By the end of 200 1 year, the market price of rex rabbit skin has fallen in an all-round way, and the ups and downs of rex rabbit breeding industry have become an indisputable fact.

In the face of this harsh reality, the author analyzes the inducing factors of the rapid rise and fall of rex rabbit skin with his own experience, in order to find out some regular things from it, so as to warn people to take fewer detours in the future and strive to guide the rex rabbit industry into a healthy and orderly development track.

2000 is recognized as the "Golden Year of Rex Rabbit" by the rabbit industry. At one time, the unified price of endothelium rose to about 45 yuan per piece, and the price of first-grade leather was higher. 200 1, the overall trend of the market is thousands of miles, except for 10, which rebounded slightly, and the rest of the time showed a downward trend. The quality requirements of rex rabbit skin were relaxed in the new year, and the purchase of equivalent skin only accounted for 8.04% of the total purchase; In the autumn, the quality requirements of rex rabbit skins are strict, and the purchase amount of equivalent skins accounts for 12.3% of the total purchase amount. Strict inspection requirements make the actual market price of rex rabbit skin drop even more.

First, the inducing factors of ups and downs

In addition to the inherent characteristics of rex rabbit skin, there are the following inducing factors:

1. Price and value are out of balance. At present, the cost of raising a 2.5 kg commercial rex rabbit is around 25 yuan, but at the peak of 2000, its price was close to that of 60 yuan (including rabbit skin and rabbit meat), and its profit was more than double its cost, which was obviously unbalanced in the price comparison of agricultural products. This is actually a dangerous signal that the high market price of rex rabbit products will not last long.

Speculation distorts the market price. Pay attention to all kinds of media reports about rex rabbits in 2000, and everyone will feel that the breeding prospects of rex rabbits are bright. Many people want to get a share in the surging upsurge, ignoring the quality standards of rex rabbit skin and grabbing it at first sight, which virtually raises the market price to a higher level. At the same time, it also contributed to the decline of rex rabbit population quality.

Some foreign businessmen bought a lot of inferior skins when they were hungry, which made them demanding when placing orders in the future. In addition, the rapid growth of rex rabbit breeding in China has made the market price fall back an inevitable result.

3. The bearing capacity of producers is fragile. Due to the lack of necessary psychological preparation, the vast number of farmers who have joined the rabbit craze are vulnerable. When the market plunged, they destroyed cages and killed rabbits one after another, which led to a sharp increase in the market volume of rex rabbit skin in autumn and winter of 200 1 and a drop in the market price of rex rabbit skin, which dealt a heavy blow to the immature rex rabbit skin market.

Second, some thoughts on the normal return of the market.

Reasonable market positioning is what producers, operators and consumers yearn for. Promoting the normal return of the market depends on the relative balance between supply and demand and the further development of the consumer market. The author believes that the above goals can be achieved in a short time as long as the following efforts are made.

1. Promote moderate scale operation, stabilize output and improve product quality. Accelerate the circulation of commodities and standardize the order of market economy.

2. Change the traditional practice of attaching importance to production development and neglecting circulation, and strive to create an honest and trustworthy scope of economic activities.

3. Carry out innovative product processing, cultivate, enlarge and activate the market, and lengthen the industrial chain.

In recent years, the processing speed of rex rabbit skin products has been accelerated. With the further improvement of people's purchasing power, rex rabbit fur products with moderate prices will gradually occupy a place in the huge domestic clothing consumption market.
