This year fur animals, such as foxes, badgers, crickets, etc., have lower reproduction levels than in previous years. Most litter size and survival rates are not high. Through surveys and analysis of the causes, they are summarized in the following aspects: Factors in the breeding and management of foxes Condition adjustment is one of the important factors that determine the breeding effect. With the improvement of breeds, the body condition index should also be improved. The body condition of the breeder animal is not static, and the â€œwild-likeâ€ adjustment should be promoted, and the coordinates should be based on the growth period. Differently, they are represented by curves. In the past few years, the reproduction effect of the above method was quite satisfactory. The specific index remains to be studied, discussed and practiced by all of us. I suggest that the body condition index of the blue fox is adjusted to be between 90-115, at least not less than 85, and not more than 120 at the highest; the body condition index of the silver-black fox should be controlled at 80-. Between 100 and 100; the body mass index of leeches should be controlled between 24-26; the body mass index of fleas should be controlled between 100-125 (preferably between 110 and 120), and the mother body condition should be medium Or slightly above average. Nutritional factors In addition to paying attention to the balance of protein, carbohydrate, and fat, we should also pay attention to the balance of vitamins, minerals, and trace elements, should be raised according to the breeding standards, can not be arbitrarily increased or decreased, or the supply is insufficient, or cause waste It even caused poisoning. It is best to choose full-price feeds or premixes with good technology, good reputation and stable quality, and feed them according to the instructions. Factors affecting the livelihood of farrowing Specific methods for artificial monitoring of farrowing and keeping alive: Pay attention to observing the maternal beast and find that it is difficult to deal with the disease as soon as possible. First check whether the cervix and pelvis are open or not. If the mother animal is normal, you can inject oxytocin (1ml) or pituitrin (2ml); if you do not see the beast out in 30 minutes, implement artificial midwifery, and the midwifery will not be effective. The above is best done by professional technicians. If the mother animal is a normal childbirth, check it immediately after delivery. In the first step, the mother beast should be quickly captured to check whether the fetus has been completely removed. If the fetus is still being treated as dystocia. The second step is to check whether the hair around the breast is pulled out. If it is not pulled out, perform manual hair removal. The third step is to check whether there is milk in the breast. If there is no milk or less milk, inject 2ml of pituitrin. The fourth step is to inject postpartum Kang and other drugs (a drug available in veterinary drug stores, preferably containing Motherwort). If not, you can inject an ampicillin (or 800,000 units of penicillin) + Antongding 2ml + dexamethasone 2.5-5mg. At the same time check the beastly condition, pay attention not to have an odor on the hand (preferably to wear a clean cotton gloves), to find the tangled or too long cord of the umbilical cord to be cut off, artificially resuscitation for artificial death, if there is weak, in the warm place to rejuvenate , You can drop a few drops of breast milk or artificial milk, Aberdeen too much (13 or more) or the mother animal is not maternity, you can implement the replacement, forced breast-feeding or artificial feeding. After the inspection, the female beast is placed back through the front. If there is a stress response, the female beast can be kept quiet for 1 hour in the production box. Postpartum can take 3-5 consecutive days of antibiotics. Pay attention to the condition of the mother afterwards and find that the problem is handled at any time as appropriate, pay attention to less disturbing the female beast, and make supplements to the beast for 15-20 days. Climate factors We have no way to change the climate, but we can prevent it by strengthening the management of feeding. Artificial insemination factors Although the mature insemination technology of FoxTiture is mature, the insemination team levels are uneven, the technology is not closed, the quality and density of the semen, the disinfection process, the quality of the dilution liquid, the estrus identification of the female beast, and the insemination site Many problems still plague us. Farms and households must choose carefully. Disease factors With the increase in the amount of fur animal farming, the types of diseases are also gradually increasing. This is not alarmist. Bacteria, viruses, parasites, fungi, mycoplasma, chlamydia and other diseases occur frequently in fur animal breeding. The area is gradually expanding. The main diseases affecting the reproduction of fur animals this year are mainly concerned with Gardnerella vaginalis, Pseudomonas aeruginosa, Eperythrozoonosis, and "White nose disease" (reported to be a nutritional metabolic disease). The specific protective measures are: Raising the fur and beasts' feeding and management levels and enhancing the resistance of fur animals to disease. And through drug treatment, purify the herd. Timely immunization to avoid immunization and prevention. Adhere to regular strict disinfection.
