Rex Rabbits Xia Chuan brings good technology
Breeding is an important part of the production of rabbits, but due to the hot summer weather, especially when the outside temperature is higher than 30°C, the rabbit's libido declines, sperm motility decreases, and the concentration decreases. The rate of female estrus is low, only 20% to 40%, and the conception rate, litter size, survival rate have been greatly affected. According to the author's production practice, to make the female rabbit perform better in the summer production performance should be as follows:
First, provide a suitable temperature
The optimum temperature for growth, production, and reproduction of Rex rabbits is 15°C to 20°C. The critical temperature is 5° C. and 30° C., that is, the environment of 15° C. to 25° C. is most suitable. In summer, the temperature is high and the humidity is high. The sweat glands of rabbits are underdeveloped. The appetite is often reduced due to heat, the body is thin, and the resistance to disease is reduced. Indoor rabbit houses should open doors and windows to allow air circulation, but avoid direct sunlight on rabbit cages. When the room temperature is higher than 30°C, splash water can be lowered to the floor, but high temperature and humidity should be avoided. Indoor ventilation fans and other exhaust equipment can also be installed. If you can spray in the rabbithouse cooling effect is better. Open-air rabbit farms should establish shelters or grow climbing plants such as loofah and grapes as early as possible to avoid direct sunlight in rabbit houses. Vitamin C or electrolytic cubes can also be supplemented in drinking water.
Second, careful feeding and management
1. Adjust the feeding time. Summer is hot and you need to adjust the feeding time. Must do breakfast early feeding, dinner late feed, feed high quality green feed at noon through the author production practice, concentrate 70% should be focused on feeding in the morning and evening to reduce the day's intake and activity.
2. Pay attention to supply clean drinking water. In the summer, as the temperature continues to rise, the water intake of Rex rabbits is also increasing. Once the water supply is insufficient or the drinking water is not clean, it will affect the normal growth and development of rex rabbits, and it will also cause rex rabbits to become infected. Therefore, it is necessary to ensure that the rabbits have clean drinking water for 24 hours.
3. Prevent disease. In summer, special attention should be paid to the prevention of rabbit lice and coccidiosis. For the prevention of rabbit plague, it is necessary to inject rabbit lice vaccine on time; for the prevention of coccidiosis, anticoccidial drugs can be added to the feed or drinking water, and the drugs should be used alternately with 2 to 3 kinds; for the prevention of digestive tract diseases, regular drinking can be performed 0.01 % of potassium permanganate water
4. Do a good job of environmental hygiene. In the summer, the feces and dirt in the rabbithouse should be promptly removed to prevent breeding of mosquitoes and flies. The food bowl should be cleaned once a day, the ground should be sprayed with disinfectant water regularly, and disinfectant should be used alternately with 2 to 3 kinds.
Third, timely and appropriate injection of oxytocin injection
In the hot summer season, no matter how many or small the number of pregnancies is, if the delivery is delayed for 2 to 3 days, the survival rate of the pups is not high, generally 10% to 30%. In this case, intramuscular oxytocin injection can be 2 to 3 units, not more than 3 units (1 ml: 10 units/intramuscular injection 0.2-0.3 ml, not more than 0.3 ml), the pups can eat To colostrum. If the time of oxytocin injection is early, although the survival rate of pups is also high, the female rabbit's colostrum will be postponed for 1 to 2 days. In this case, the female rabbit may be given brown sugar water or 1 bottle of raw milk (100 (ml/bottle), even for 3 days, can also be used by other rabbits for several days. If the amount of injections is unsuitable, the survival rate of the puppies will decrease, and the life of the female rabbit may also be endangered.
In the summer, appropriate amount of oxytocin injection is given in due course. If the baby rabbits produced are well-fed and managed, the survival rate can reach 95% or more.
Therefore, in order to improve the reproductive performance of Rex rabbits in the summer, it should start with technology and management, so as to make full use of the summer to improve economic efficiency.
Vitamins are a class of organic compounds necessary to maintain good health. This kind of substance is neither a raw material for body tissue nor a source of energy in the body, but a kind of regulating substance, which plays an important role in material metabolism. These substances are often supplied from food because they are not synthesized or are insufficiently synthesized in the body, although they are rarely needed.
Vitamins, also known as vitamins, are, in popular terms, substances that sustain life, are a class of organic substances necessary to maintain human life, and are also important active substances for maintaining human health. Vitamins are low in the body, but they are indispensable. Although the chemical structures and properties of various vitamins are different, they have the following in common:
1 vitamins are present in food in the form of provitamins;
2 vitamins do not constitute a component of body tissues and cells, it does not produce energy, its role is mainly involved in the regulation of the body's metabolism;
3 Most of the vitamins, the body can not be synthesized or the amount of synthesis is insufficient, can not meet the needs of the body, must be obtained through food;
4 The human body needs a small amount of vitamins. The daily dose is usually calculated in milligrams or micrograms, but once it is lacking, it will cause the corresponding Vitamin deficiency, which will cause damage to human health;
Vitamins are different from carbohydrates, fats and proteins. They are only a small percentage of natural foods, but they are necessary for the human body. Some vitamins such as B6.K can be synthesized by bacteria in the intestines of animals, and the amount of synthesis can meet the needs of animals. Animal cells can convert tryptophan into niacin (a type B vitamin), but the amount of production is not enough; vitamin C can be synthesized by other animals except primates and guinea pigs. Plants and most microorganisms can synthesize vitamins themselves, without having to be supplied from outside the body. Many vitamins are part of a prosthetic or coenzyme.
Vitamins are some small amounts of organic compounds necessary for human and animal nutrition and growth. They are extremely important for the metabolism, growth, development and health of the body. If you lack a certain vitamin for a long time, it will cause physiological dysfunction and cause certain diseases. Generally obtained from food. There are dozens of kinds found at this stage, such as Vitamin A, vitamin B, vitamin C and so on.
Vitamins are essential organic compounds in the metabolism of the human body. The human body is like an extremely complex chemical plant, constantly carrying out various biochemical reactions. The reaction is closely related to the catalytic action of the enzyme. Enzymes must be enzymatically active in order to produce activity. Many vitamins are known to be coenzymes of enzymes or constituent molecules of coenzymes. Therefore, vitamins are important substances for maintaining and regulating the normal metabolism of the body. It can be considered that the best vitamins are in the form of "biologically active substances" and are present in human tissues.
