Causes of formation of raccoon dogs and its prevention and treatment

Raccoon dogs refer to those who cannot be bred into commercial raccoon dogs during the breeding period after litter weaning. The performance is not long, small, bony, dishevelled coat, to the breeding period can only grow to 2.5~3.5kg, out of the hurdle can only take the residual skin.

1 the reason for the formation of rigor raccoons

1.1 Feed collocation is unreasonable and nutrition is not fully priced. Breeders want to save by feeding only corn or with very little other feed. Due to the serious lack of nutrition in feed, it can not meet the growth needs of raccoon dogs, resulting in the lack of growth of raccoon dogs, which is the main reason for the formation of stiff raccoon dogs.

1.2 the milk of mother raccoon dog is insufficient. The reasons for insufficient milk of female raccoon dogs: ① genetic factors, congenital lack of milk; ② feed quality of female raccoon dogs is poor, so that female raccoon dogs can not produce enough milk; ③ female raccoon dogs get sick during lactation and lack of milk. Due to the lack of milk of the mother raccoon dog, the young do not have enough to eat, the body is weak, and the weight is light after dividing the litter (the weight of the normal raccoon dog is 1.5kg after 45 days). The raccoon dog with less than 1kg is easy to form a stiff raccoon dog.

1.3 mothers give birth to too many babies. For example, the birth of 13 babies is 18, but can not be replaced. Due to the lack of milk, some of the raccoon dogs do not eat enough milk, and they are small and become stiff after weaning.

1.4 although there are not many babies born to mothers, they produce one or more small raccoons, that is, the so-called "last dregs". Such raccoons are easy to form stiff raccoons.

1.5 raccoon dogs were not cured or cured. For example, long-term dysentery, big claw disease, infectious hepatitis and other diseases have not been cured, forming raccoon dogs.

1.6 acariasis and fungal dermatosis are not cured, so it is easy to form racoon dog.

1.7 in the early stage of breeding, raccoon dogs are stiff due to trauma, such as fractures, falls, bites and so on.

1.8 A mother raccoon dog has a bad habit of carrying a cub. Individual raccoon dogs were injured before weaning, and the injury did not heal for a long time after weaning, and finally formed a stiff raccoon dog.

1.9 although the congenital physiological defects of more than 1.9 generations of inbreeding, raccoon dogs survived, but the physique of raccoon dogs declined, the disease was weak, and finally formed stiff raccoon dogs.

2 Prevention of raccoon dogs

2.1 after weaning, raccoon dogs are fed with full-price fodder. Within 10 to 20 days after weaning, it is best to add some milk, eggs or soy milk to make the feed taste good, eat well, rich in nutrition and conducive to growth.

2.2 for the mother raccoon dog with a large number of offspring, part of the baby raccoon dog should be transferred to foster care; if you cannot find a suitable mother raccoon dog substitute, you can throw away a small part (generally, the mother raccoon dog can be raised less than 10). Although some mother raccoon dogs do not give birth to many babies, they produce 1 or 2 very small raccoon dogs, which can be abandoned as appropriate.

2.3 Mother raccoon dog milk is insufficient, first determine whether it is congenital milk deficiency or malnutrition, or mastitis. If congenital milk deficiency can be used to promote milk, each injection of prolactin 50g 100g, at the same time feed pig hoof plus dandelion (boiled). If it is malnutrition, add milk, soy milk, eggs, fresh fish to the feed, and inject dexamethasone 5mL. If these methods are not effective, some or all of the young raccoons can be transferred to other mothers, or artificial feeding.

2.4 for sick nests of raccoon dogs, it is necessary to strengthen treatment so as not to let the disease haunt them. For those who cannot be cured within 1 month after nesting, they can be ruthlessly abandoned.

2.5 do not inbreeding, change the male raccoon dog or female raccoon dog in time, establish the farm file, and introduce the species from a long distance once every 3 ~ 5 years.

2.6 try to eliminate the old raccoon dogs or the young mothers who give birth to irregular babies, and stop the occurrence of stiff raccoons from the source. It is also necessary to eliminate the mother raccoon dog whose milk is insufficient. Such mother raccoon dog not only has bad milk but also inherits the next generation. When selecting seeds, you must choose the mother raccoon dog with good milk as the seed, which is one of the effective measures to prevent the formation of stiff raccoon dog.

3. Treatment of raccoon dogs.

3.1 for small raccoon dogs caused by large litter size and poor milk, they should be fed in a single trough after litter division. On the basis of full-price ingredients, add milk, eggs, soybean milk, but not easy to feed too much, too full, to eat less and more meals, 5 or more meals a day. No more than 100g of milk and soy milk per day, no more than 5g of eggs per day, and no more than 3 to 4 meals of milk should be mixed with food, and each of them should be fed with 3-5 yeast slices per day.

3.2 the rats were injected intramuscularly with 250 μ g VB12 and inosine 1mL for 7 days.

3.3 for young raccoon dogs with scabies, the treatment should be strengthened. 0.5% Xinmianlaoling medicine should be used for 3 minutes, and the whole body should be washed; 1% trichlorfon, enemy kill, etc., can also be used for medicine bathing; each animal can also be injected again after killing 0.2 mL for 7 days.

3.4.The additive can be fed with 1 g per 7kg body weight, fed with mixed feed for 2 days, then once every 15 days, 8 times before breeding, and has the effect of preventing parasites and dysentery.

3.5 for those who are ineffective in prevention and treatment, they can be killed and buried deeply.
