At present, the captive otters have ended estrus mating and entered the period of pregnancy control. Since leeches are in the category of eating less and having an intense temperament in fur animals, it is very important to keep them during gestation. Many farmers have had such experience. Obviously, after seeing the waterfowl mating succeed, after a period of feeding, they find that the species is not pregnant at all. In fact, the occurrence of this situation was largely due to improper handling of feeding quantity, species selection, and environmental protection during this period, which eventually led to the absorption of the carcass. Most leeches have a gestation period of about 47 days. After confirming successful mating, the gestation period begins. At this time, the method of feeding should be maintained twice a day, the same as morning and evening, and the amount of whole-day feeding is 20 grams of corn flour, 25 grams of fishmeal, 50 grams of eggs and chicken (cow, pig, etc.) Liver In general, the proportion of eggs is larger, livers are less, but the total amount must be guaranteed. When feeding, the food intake of two meals should be balanced. When raising a large number of breeders, errors must be avoided when calculating the total amount of cooked food. When the otters enter the early stage of pregnancy, farmers should complete the maternity housing. The use of clean straw or wheat straw to pave the custom of the maternity maternity room, do not wait until the second trimester of pregnancy or labor when operating again, otherwise pregnant or abortion will cause fatal threats. Pregnancy must live in a comfortable and calm environment during pregnancy. No one other than a keeper can enter the culture zone, and noise such as noise, loud noise or firecrackers can't be heard. Keeping pregnancies and maintaining good environmental conditions is critical to pregnancy. There is a point that farmers should bear in mind that during pregnancy, pregnancies may have some symptoms, such as dryness of the nose and other "burn" symptoms, under normal circumstances, relying on their own immune function and antibodies, the disease will gradually disappear. Even if there is no improvement for a few days, in principle, it is not possible to administer drugs or inject drugs. Otherwise, it will lead to the termination of pregnancy and miscarriage and stillbirth. As customers have higher and higher requirements for animal reproduction and animal disease diagnosis and treatment, traditional diagnostic methods such as visual inspection, stethoscope listening, thermometer inspection, and percussion and hammering can no longer meet the needs of animal husbandry production and veterinary clinics. Today, B-ultrasound is playing a big role in human medical diagnosis, and in the future, B-ultrasound will also play a role in animal medicine. We should promote the use of veterinary ultrasound scanner step by step according to the actual situation, popularize the knowledge of the use of veterinary ultrasound scanner, take this as an opportunity, and use it as a ladder to improve the level of veterinary practice in our country.
