Winter Rabbit Management Technology Points to Note
The management of breeding rabbits is extremely important, especially in winter, when the temperature is low, the sunshine time is short, and the green and green fodder is lacking, which brings certain difficulties to raising rabbits. If improperly reared and managed, it will not only cause increased consumption of feed, increase the mortality of the disease and increase expenditure, but also seriously affect the quality of fur, but also restrict the rapid development of production. Winter feeding and management focus is to do a good job of cold insulation and winter winter breeding work. Rabbits in winter feeding and management should pay attention to the following points. Do cold insulation Rex rabbits are afraid of heat and are more cold-resistant, but their cold-resistance capacity has a certain limit. Temperatures below 5°C will feel uncomfortable. Naked colorless puppies are particularly afraid of freezing. Below 10°C, they will freeze and freeze. Below 5°C, they will freeze. dead. Therefore, it is very important to keep the rabbits afloat during the winter to do a good job of keeping warm and cold. 1. Although the winter temperature is low, but in addition to newborn puppies, the rabbithouse temperature does not require very warm, but requires its temperature to be relatively stable and can not be hot and cold. In winter, the optimum temperature for the growth of rabbits should be 15°C~25°C. Overcooling and overheating have a great influence on their physiological functions, generally not lower than 10°C and higher than 29°C. 2. Increase the stocking density, rely on the rabbit body to increase the temperature; the young rabbits should not be raised in single cages, and the puppies must be moved into a warm room. 3. Indoors rabbits should be closed doors and windows to prevent the thief wind invasion; outdoor rabbits, the cage door should be hung a good straw curtain to prevent cold wind intrusion. Try to minimize the amount of ventilation in order to save the heat generated by the rabbit body. 4. Full and reasonable illumination is a necessary condition for normal growth and development of Rex rabbits. Generally, artificial lighting and natural lighting are commonly used. The transparent plastic film can be covered before and after the rabbit house to make full use of the sunlight, maximize the amount of indoor lighting, and artificially increase the temperature. Rex rabbits can obtain good production performance under light conditions of 12 hours to 16 hours per day. Conditions can also be installed in the heating equipment, such as heating, electric heaters, stoves and so on. Strengthen feeding management 1. Supplement feed supply. Due to the low temperature in winter, rabbits consume more calories. Therefore, the daily feeding amount of large and small rabbits should be 20%~30% higher than usual, and the proportion of high-energy feeds should be appropriately increased. In addition, due to lack of green feed in winter, prone to vitamin deficiency, should try to feed some leaves, carrots, barley malt and tuber-like feed, etc., to supplement the deficiency of vitamins. 2. The powder should be added with a small amount of bean dregs or bran, warmed with warm water and then fed, and do less feeding Tim to prevent the remaining material after eating ice. 3. Use wet powder when feeding with coarse powder. Coarse powder should be mixed and stirred uniformly. Before feeding, mix 1:1 with warm water and wet. Generally, grasp the hand wet material without dropping the water between the fingers. It is used nowadays. It is not suitable to mix more to keep the feed. Freshness, palatability. 4 reasonable with feed. Rex rabbits are herbivores. Since feeding artificial grass exclusively to feed green grass can not meet the nutritional needs of rex rabbits, in addition to feeding some fresh and fresh feeds on a regular basis, they must be equipped with full-rate pellet feeds in a certain proportion. The benefits of the full-price pellet feed are: not freezing in winter, mildew in summer, relish in rabbits, and comprehensive nutrition. When mixed feeding, green feed should be used in a variety of combinations, fresh and clean, and supplemented with sufficient supplements. When eating freely, the content of various nutrients in the mixed feed should be controlled at 10.46 kJ~11.72 kJ for each kilogram of feed, 18% for the crude protein prophase, 14% for the later period, and 3%~5% for the crude fat. Fiber 12% ~ 15%, calcium 0.5% ~ 0.7%, phosphorus 0.3% ~ 0.6%. Scale feeding should use full price with granular feed. When free-range, it is advisable to adopt coarse green, and then make up fine material. Do a good job in rabbit house hygiene and wintering pests In winter, special attention should be paid to improving the environmental hygiene of rabbit houses and regularly disinfecting the rabbit houses. Disinfection requires the disinfection of more than two kinds of disinfectants to prevent the occurrence of drug resistance; the rabbit house should be cleaned frequently, remove the excrement and dirt every day, use damp lime to prevent moisture, keep the house clean and dry, and prevent the accumulation of excrement and reduce it. The production of irritant gases such as ammonia gas and hydrogen sulfide prevents respiratory diseases such as rhinitis and pneumonia. In addition, the disinfection should be serious and the rabbit house should be kept dry. In order to keep warm, the rabbit house in winter has increased hermetically, but with poor ventilation and increased harmful gases such as ammonia gas, hydrogen sulfide, and sulfur dioxide, it is easy to induce retinal diseases such as conjunctivitis and rhinitis. Therefore, ventilation equipment should be installed and automatic ventilation should be strengthened. You can open the doors and windows from 11 noon to 2 pm every day, use the natural wind to change the air, and grasp the smell at any time. In order to make the rabbit safe winter, enhance the body, apply ivermectin or avermectin, insect repellent net and other drugs before winter (late autumn), and take injections or spices to take all rabbits and young rabbits once Extermination of internal and external parasites to prevent the invasion and harm of parasitic diseases. Do a good job of winter breeding While doing a good job of cold insulation work, it is very important to arrange winter winter breeding. Its advantages are high survival rate and slaughter rate. The puppies grow fast, have a large body size, are physically strong, have a high yield, and are most suitable for planting. As long as the work of protecting against cold and warmth is seriously conceived, breeding and mating in winter will still achieve better results, especially if the young and young rabbits have high survival rates and few diseases. In actual production, as long as the insulation of the litter box is done, the bedding is dry, soft, strong in heat insulation, and has good hygroscopicity. If the temperature is maintained at 5° C. or higher, a good wintering effect can be obtained. In winter, the temperature is lowered, the pathogenic microorganisms are inactive, there are fewer infectious pathogenic microorganisms, the rabbit disease is less, and the survival rate of the young rabbits is high. It is entirely possible to create a constant temperature environment for the bunnies and winter winter breeding. Although the female estrus is not obvious, but after all, can estrus, able to ovulate normally, therefore, we should seize the opportunity to breed female rabbits, breeding time should be selected at noon on sunny days, no wind, warm day. It is necessary to grasp the good agricultural practices in breeding: Pink is early, Black and Purple is late, and Dahong is at that time. In order to increase the conception rate, the mating method can be repeated or double mating. In addition, 12 days after mating, the female rabbits should timely touch the tires. The method of touching the tires is to hold the female rabbit's ears and collars in the left hand and fix the female rabbits on the flat ground or the desktop so that the rabbit heads towards the touching tires. The person's chest, the right hand was inverted in a figure eight shape placed in the abdomen of the female rabbit, gently from the back to explore, the embryo was spherical and elastic, dung ball was hard spherical, and inelastic. For empty pregnant female rabbits who are not pregnant, they must make up for it in time. In addition, the winter rabbit breeding period should be long, generally do not engage in blood matching, to breed 1 to 2 children is appropriate.

GMP in China's veterinary drug industry began to be implemented in the late 1980s. In 1989, the Ministry of agriculture of the people's Republic of China issued the code for quality management of veterinary drug production (for Trial Implementation), and in 1994, the detailed rules for the implementation of the code for quality management of veterinary drug production (for Trial Implementation). From October 1, 1995, all qualified drug manufacturers (workshops) and drug varieties can apply for GMP certification according to the requirements. The administrative department of health shall give priority to the enterprises (workshops) that have obtained the GMP certification certificate when applying for the production of new drugs. As of June 30, 1998, for enterprises (workshops) that have not obtained GMP certification, the administrative department of health will no longer accept applications for new drug production.
On March 19, 2002, the Ministry of agriculture revised and issued the new veterinary drug production quality management specification (hereinafter referred to as veterinary drug GMP specification). Announcement No. 202 was issued on June 14 of the same year, stipulating that the transition period from June 19, 2002 to December 31, 2005 is the implementation of GMP for veterinary drugs, which shall be enforced from January 1, 2006. Since then, China has poured out a large number of GMP veterinary drug enterprises
