In recent years, Rex rabbits have a better market outlook. Some provinces and cities in the country have actively developed Rex rabbit breeds. After many years of expansion and breeding, fine rabbit breeds imported from abroad have begun to enter domestic and international markets. Raising rabbits in the countryside, cages can be adapted to local conditions and draw materials locally. This article discusses several insights on the feeding and management aspects of Rex rabbits.
1, breeding
The suitable mating female rabbits are from July to August, but not earlier than June. The appropriate body weight is 2.5-3.0 kilograms; male rabbits have a mating age of 8-9 months and a body weight of 3.5-4.0 kilograms. Artificially assisted by the four breeding methods, repeated mating refers to using the same male rabbit to mate with the same female rabbit 2 times in the same breeding period, 2 times at intervals of 4-6 hours. Double mating means that female rabbits are mated with two different male rabbits within the same breeding period, with two intervals of 30-120 minutes. Multiple mating refers to the same female rabbit in a breeding period, using more than two different male rabbits to mate every 30-120 minutes. The blood-matched females were bred in the first 3 days after delivery, and the conception rate was high, which in turn increased the reproductive density. Usually a male rabbit can bear the breeding of 10-15 female rabbits, and can rest for 1 day after 2 days of continuous breeding. The average gestation period for females that are generally pardoned is 30-31 days. Spring is a good breeding season for female rabbits. It is stressful to let Rex rabbits have more than 2 litters in the spring. In the summer, it is hot and humid, and do not allow the pardons to breed in summer. In the autumn, females have a strong estrus, which is another good season for Rex rabbit breeding. The temperature in the north is low, and the green and green fodder is lacking. However, in the rabbit farms with green feed, breeding can be done in winter as usual.
2, the ratio of nutrition and feed
Recipients of protein requirements in the growth of rabbits, pregnant rabbits, lactating rabbits in the diet should contain crude protein 16%, 15% and 17%. The fat content of rabbits in the rabbit diet was 2%-3% in growing rabbits, 3%-4% in pregnant rabbits, and 4%-6% in lactating rabbits. The suitable content of crude fiber in rabbits' diets is 12-/0-16%0. Young rabbits can be appropriately lower, but not less than 8%. The minerals needed by Rex Rabbits can be divided into two categories according to their content in the body: The first is the constant element, mainly calcium, phosphorus, sodium, aluminum, potassium, magnesium, sulfur; the second is trace elements, with iron , copper, zinc, manganese, cobalt, iodine, selenium and so on. The mineral requirements for growing rabbit diets were: calcium 0.34%, phosphorus 0.22%, sodium 0.2%, and sulfur 0.04%. The vitamins needed for rabbits can be divided into two major categories: fat-soluble vitamins (vitamin A, vitamin D, vitamin E, vitamin K) and water-soluble vitamins (vitamin C and B family vitamins). Rex rabbits need water every day, usually 2-3 times the dry feed intake.
The approximate proportion of general raw materials for grain use is 35%-45% for roughage (hay, straw, vines, etc.) and energy feed (corn, barley, etc.) 25%-35%. Plant protein feed (various types of cakes, etc.) 5%-15%, animal protein feed (such as fish meal, etc.) 0%-50%, inorganic salt feed (bone meal, stone powder, etc.) l%-3%, feed additives (including trace elements, etc.) 0.5%. 1.0%. Note that, 1 feed quality is an important factor related to Rex rabbits. Formulated feeds should be strictly prohibited from using all kinds of moldy, low quality feed. 2 Make full use of local feed resources. The use of feed should consider economic benefits, and make full use of local nutrient-rich, low-cost feed resources, especially protein feeds, such as the use of alfalfa dry powder, in order to reduce feed costs. 3 in accordance with the physiological characteristics of digestion. Rex rabbits are monogastric herbivores and prefer to eat plant feeds. They also like to feed pellet feeds but do not like powder feeds. The appropriate crude fiber content is conducive to maintaining the normal physiological functions of digestive tract and the digestion and absorption of nutrients. If the crude fiber content is too high or too low, it will have adverse effects on the intestinal peristalsis and secretion of digestive juice. 4 The diet should be relatively stable. The method for assessing the pros and cons of the formula is to conduct a small-scale feeding experiment. Once it is determined that the combined diet rabbits are fond of food and grow fast, the feed conversion rate is high and the cost is low, they should be kept relatively stable and should not change so much as to avoid Bad influence. If it must be replaced, it needs to be gradually carried out so that the rabbit has an adaptation process.
Rex rabbits are reared mainly in green and coarse, and generally green materials account for 60%-70% of rations, and coarse and fine materials are 30%-40%. Feeding should be diversified, drinking water should be fresh and clean, and replacement of feed should be gradually carried out. Rex rabbits are sweet and vegetarian, and don't like powdery, smelly feeds. When feeding powder, it is necessary to mix with water and then feed it. Otherwise, it can easily be sucked into the air intake and cause respiratory diseases. When feeding, it is necessary to be regular, quantitative, but also flexible, you can take "seven see feeding method." A look at weight, body weight and more to feed some; second look at the wolfberry into a good and less good; third look at the stool, such as dry, to increase the green feed, increase drinking water, otherwise it is the opposite, if necessary, feeding drugs; When looking at hunger and fullness, it is appropriate to increase the amount of feeding. When looking at age, adult rabbits have fewer feeding times, usually 3 days per day, middle-aged rabbits 4-5 times, and newly weaned rabbits 5-6 times per day. Request to feed the quality of good digestible feed; six to see the number of litters, breast-feeding more rabbits, puppies have begun to eat, to set more feed grains, more feed; seven to see the season, summer heat, feeding morning Feeding early, at noon fine and less, to feed at night. Cold in winter, you need to feed in the morning, eat well at noon, eat at night, add night grass at night, and pay attention to add juicy feed. More hay is fed during the rainy season, and more green material is needed during the dry season. In addition, the nutritional requirements for Rex rabbits are: 10.0-11.3 MJ/kg of digestive energy. Crude protein 15% -18%, crude fiber 12% -14%, which feed the rabbit feed requirements, digestive energy, high crude protein content, low crude fiber content. Http://
