Rex ways to improve conception rate in winter


Yinan 276,300) winter cold, low temperature and sunlight n, il '~-J short, coupled with the lack of green feed, breeding of Rex adversely affect reproduction. As far as I know, every winter to breed Rex has happened repeatedly with infertility, especially in farming households. In order to improve economic efficiency rabbit, rabbit author based on many years of practice, summed up the winter several ways to improve conception rate Rex Rabbit, dependent rabbit reference. l breeding females increased more appropriate illumination light hours of the 16h. Natural light in winter time is only 10 ~ 1lh. Need to add artificial light a day 5 ~ 6h, can be taken as early as complement, that is, before sunrise added 5-6h; night meeting, now behind the additional 5 ~ 6h. Also can be implemented sooner or later,[link widoczny dla zalogowanych], make up, that is,[link widoczny dla zalogowanych], before sunrise and sunset each additional 2.53h. 4W per square meter of light intensity is appropriate. 2 strengthen the insulation-free homes, improve energy feed ratio of the critical temperature of Rex were 30 ��, 5 ��. Breeding females in winter the minimum temperature should be controlled in more than 8 �� ~ l0 �� in order to have a higher heat rate, to facilitate breeding. In order to improve the body's ability to keep out the cold, the outside temperature changes should be based on the strength of the feed formula to adjust the energy feed (maize, etc.), the ratio can increase more than summer, 2 to 4 percentage points, to facilitate the normal estrus females. 3, vitamin A, vitamin E, vitamin D and other winter due to lack of green feed, Rex from the feed intake of various vitamins decreased. Especially for breeding play a decisive role of vitamin A, vitamin E, vitamin D and so should pay attention to add. Per kg feed in the vitamin A8000 ~ 10000IU,[link widoczny dla zalogowanych], vitamin E50 ~ 60rag, vitamin D900 ~ 1000IU as appropriate. AD can also be used commercially available vitamin powder, feed additive per 50 kg 200 ~ 300g; 121 �� cod liver oil, each rabbit daily 3 ~ 5mL, used in conjunction 7 ~ l0 days; also be adding an appropriate amount in the feed, soybean oil, peanut oil,[link widoczny dla zalogowanych], vitamin E supplement deficiencies. According to practice, observation, females daily supplement of 50-60g of carrot b, on the estrus and lactation is very good. 4 timely treatment of disease on the physical breeding females should be reduced too much fat concentrated feed Feeding Amount, multi-green succulent forage feeding and regular exercise every day. Of females suffering from endometritis can be injected pituitrin 510U, or 0.05% saline solution rinse Furacillin uterus, once a day, 3-5 times; of pyometra in females, injection pituitrin, drug flush the uterus, uterine infusion of 10% brine 2030mL, penicillin, streptomycin, 100,020 million units each, are available several times; on the risk of inflammation of the females with normal saline, 2% sodium bicarbonate solution, 0.1% or 0.02% potassium permanganate solution, rinse Furacillin uterus. Rabbit oral medication to prevent pollution-free production notes Hill Xiaxiu Mei Lu (Jiangsu Animal Husbandry and Veterinary Station Jiangyan, Jiangsu Jiangyan 225,529) exceeded the long-term abuse of veterinary drugs, especially antibiotics and hormones will be long-term use as feed additives, or use of prohibited drugs, or incorrect medication (such as dosage, route of administration according to the specified requirements, the implementation of withdrawal period is not provided), will result in drug residues, which not only reduce the quality of rabbit meat, but also hazardous to human health. In order to control drug residues, to produce pollution-free safety of rabbit meat, Rabbit pollution in the production of prophylaxis should note the following aspects: a correct choice of drug resistant pathogens, the performance of each drug are different, so preventive medication must have a choice, When a disease while there are several drugs are available, generally under the preventive effect, the effective dose, the nature of drugs, drug toxicity, drug prices, etc., a reasonable choice to use drugs. 2 Select the appropriate delivery method for different delivery methods, can affect the rate of drug absorption,[link widoczny dla zalogowanych], utilization, efficacy and duration of time there, and even lead to changes in the nature of drug. Commonly used method of prevention of drug administration, there is mixing with water delivery, mixed feeding administration, aerosol administration, dipping and other methods. Rabbit breeding in the production of the correct choice according to specific circumstances. 3 Note that the incompatibility of two or more drugs when used in conjunction, some changes will have physical and chemical properties, drug precipitation, agglomeration, change color, thus affecting the prevention or treatment, or even failure or toxicity, such as sulfa drugs (sodium) and antibiotics cable (sulfonate or hydrochloride) and role in the generation mix (in the water with sediment present), reduced efficacy. B-vitamins, vitamin C is acidic, basic drugs that break down the event failure. Carrying out drug prevention, we must pay attention to incompatibility issues. 4 prudent use of drugs that some farmers saw the sick rabbits, a
