On hot summer days, when the temperature reaches above 30°C, it will cause a series of adverse physiological and psychological reactions in rabbits, and severe death can result. Good husbandry and management, and appropriate increase in feed nutrient concentration can enhance the rabbit's physique, improve the rabbit's body temperature regulation ability, and effectively prevent or reduce the occurrence of heat stroke and other diseases. High temperatures can cause rabbits to lose their appetite and feed intake. If they do not increase the proportion of dietary vitamins, proteins, minerals, etc., the intake of vitamins, proteins, minerals, and other nutrients will be seriously insufficient. , causing a serious shortage of these nutrients, which led to a reduction in the ability of rabbits to produce. Therefore, the nutritional concentration of the diet should be increased to meet the nutritional needs of rabbits based on intake.
In addition, it is also important to choose the right feeding time. The high temperature at noon in summer and the loss of appetite in rabbits, so it is best to add some feed in the morning and evening. At this time the rabbit has a strong sense of hunger, moderate temperature, good appetite, can increase feed intake, meet the rabbit's nutritional needs . At the same time, it is also important to increase the amount of green feed to be fed. It is forbidden to feed moldy feeds and feeds such as dewy grass. Appropriate use of feed additives to mitigate the hazards of high temperatures. In addition, add appropriate amount of vitamin E, vitamin K, vitamin C, vitamin B2, biotin, and other additives to the rabbit's diet; add appropriate amounts of baking soda, bromide buffer, Huoxiangzhengqi water in drinking water, etc. It can effectively prevent or reduce the harm of high temperature on rabbits and increase the rabbit's production capacity. In addition, cooling feed (such as watermelon rind) can also be fed to increase the heat resistance of rabbits. The watermelon rind was cut into pieces. Each day, the rabbits were fed about 55 grams each day. They were fed 3 times a day. They were fed separately at noon and fed into the feed between morning and evening.
Cooling
If the summer temperature rises, if rabbits do not take measures to prevent heatstroke, they will have a great impact on the growth and development of rabbits. In order to make rabbits safe in summer, you can use a high-pressure sprayer to spray cold water from wells immediately after noon every day. Observe changes in temperature in the house and spray once every two to four hours. Generally can reduce the temperature within 3 °C ~ 6 °C. When the temperature is too high, some cool water can be poured on the rabbit house floor to increase heat dissipation and evaporation. However, it is required that the doors and windows must be opened at the same time to increase the flow rate of the wind, otherwise the excessive humidity in the house will also bring about adverse effects. It is also possible to increase the ventilation fan power, change the horizontal ventilation to vertical ventilation, increase the wind speed flowing through the rabbit body, and promptly take away the heat generated by the rabbit body to achieve the purpose of cooling and preventing heatstroke. If the above measures still cannot effectively reduce the summer heat, you can also take the following measures to ensure that the rabbits can safely pass the summer.
Take a arbor: Summer rabbits die if they are exposed to sunlight for 4 to 6 hours. Therefore, it is necessary to put shading on the open-air rabbit cage, and the closed-type rabbit house must be opened and cooled by doors and windows.
Cut rabbit hair: After entering the summer, keep the rabbit's neck, back, and waist at the hair cutting room. Other parts of the hair should be reduced by some amount. The long-haired rabbit cuts the hair 1 time before the arrival of Volt.
Decrease the density: The group rabbits should be divided into small groups so that the rabbits are not crowded and heated. Cage raise rabbits to reduce the number of cages.
Ensure drinking water: Provide enough clean, fresh drinking water, add some salt, vinegar, mint and so on in the water.
Careful Feeding: Summer rabbits seldom eat during the day and should choose to feed on cool mornings and evenings. Feed early in the morning, late at night, and feed 1 or 2 times at night to avoid feeding at noon. Should feed more green feed, and add a small amount of garlic mud, onion, leeks, etc., in order to facilitate sterilization and disease prevention. If you feed rabbits with wet material, wash and dry the bowl daily. In addition, feed the bean dregs to feed fresh, how much to feed to feed how much to feed, to prevent the remaining material moldy.
Cooling and cooling: In summer, bricks soaked in cool water are placed in rabbit cages, and rabbits can be lowered on their body to reduce body temperature. When the temperature of the cage exceeds 30°C, proper amount of well water may be splashed around the ground and walls.
Do a good job in health: high temperatures in the summer, high humidity, is conducive to bacterial growth. Therefore, ditches should be dug around the rabbit house and there should be no dead pool. The rabbithouse should be regularly sterilized and kept clean.
Adoption of rabbits: Unbroken rabbits should be kept in spacious cages, reared with female rabbits, and regularly weaned. After weaning young rabbits are adapted for 1 week to 2 weeks, 2 or 3 rabbits can be fed in 1 cage or 1 rabbit in 1 cage.
Prevention of rabbit disease
Rabbit diseases that are prone to occur in summer include salmonellosis, mucinous enteritis, rickets, coccidiosis, Clostridium perfringens, and heat stroke. Prevention can be vaccinated before the heat season. The vaccines currently used for prevention are Clostridium welchii aluminum hydroxide bacterins. Salmonella hydroxide aluminum formaldehyde vaccine. In addition, some other drugs such as chlorpheniramine tablets, oxytetracycline soda powder and garlic can be added to the feed. If a rabbit with heatstroke is found, it should be immediately transferred to a cool, ventilated place. Use a towel to immerse cold water in the rabbit's head and burl the needle at the tip of the tail. At the same time, add 4 to 5 tablets of Dan. In general, most heat shock rabbits can be recovered quickly.
Reproduction control
In summer, the rabbits consumed less food and their constitution decreased. Male rabbits' semen quality is significantly reduced, dead sperm and azoospermia are significantly increased; female rabbits are burdened with pregnancy, and are likely to cause miscarriage. The resulting rabbits are weak, and the mother rabbits have less milk secretion and are also prone to cause various diseases. ; High temperature and high humidity environment is not conducive to the growth of rabbits. Therefore, breeding should normally be suspended during the summer. If the rabbit farm with good conditions can control the temperature below 28°C, it can also be suitable for breeding breeding.
