1. The timing of breeding should be timely. The maternal estrus period is related to the light. In the north of China, the mother quack gradually erupts from about March 5 to 20, and the light is about 11 hours a day. The estrus cycle is 7-9 days and the duration is 3 days. At this time, all estrus mothers must carry out the initial allocation. After the initial allocation, they are generally separated every 9 days. They are to be compounded, and then compounded again after 24-36 hours. This will ensure that most mothers will conceive and will increase litter size.
2. Females who are not in heat during the initial phase of the deployment are delayed until the stage of reconstitution. At this time, the light is close to 12 hours, and the heat will be accompanied by estrus. For mothers who refuse to fit despite estrus, they must be forced to mate. One is to tie their mouths and forelegs to prevent them from catching and biting males, and the males can mate; the other is to mix a piece of (0.25 mg) stabilizer in the mother's feed the night before, allowing them to sleep at night after eating. The next morning can be used for public mating.
3. The mother-in-law should strengthen management after she becomes pregnant. The best meat feed is pig water, which normally accounts for 75% of the feed, and can also be fed with eggs so that the mother's body is in normal condition (abdominal flat, medium to upper); for thin (stomach, there is a gap in the middle).貂 貂 貂 貂 貂 貂 貂 貂 貂 貂 貂 貂 貂 貂 貂 貂 貂 貂 貂 貂 貂 貂 貂 貂 貂 貂 貂 貂 貂 貂 貂 貂 貂 貂 貂 貂 貂 貂 貂 貂 貂 貂 貂 貂 貂 貂 貂 貂 貂 貂 貂.

Living clearance:
Most of the leeches have a gestation period of about 47 days, and the most likely deaths are 5 days before their birth, and inspections should be stepped up. Paste the cracks in the chamber to prevent the cold wind from blowing on the main body and fill up the grass. Aberdeen piled up, indicating normal feeding; scattered chaos crawling, indicating that the mother's milk is insufficient or less effective nipples, and some food is not enough. At this time, we should even out part of the Tsai, so that the birth date is less, but the birth date is less than 3 days of the mother-in-law feeding, so as to avoid the size difference is too large, the mother-in-law refused to feed. To be raised on behalf of the bred is required to use the foster mother's armpit grass and urine to smear the entire body so that the odor is the same, preventing the mother lice from smelling odors and killing or licking out of the larvae.
Disease prevention:
After birth, Aberdeen still has to check for diseases with drought. Found that suffering from red claw disease, available vitamin C injection, the daily point of the affected area 2-3 drops, two or three times to cure. When the calves are injected at the age of 60 days, they are injected with the canine distemper vaccine once. They suffer from common diseases such as hepatic swelling, gastroenteritis and pneumonia. They need to be discovered and treated promptly. The keeper should check up the feces of the calf every morning with an advanced shed. , found that there are diarrhea or blood in the stool to make a record, so that when feeding early treatment of cohesion, with oxytetracycline into a go-between, add 1/3 feed and mix well. General gastroenteritis can be cured as long as it is found early and the sick mane can eat again. Such as recurrence, available 40,000 units of gentamycin, breaking the bottle, the liquid into a small amount of food, the general sick can eat once cured. At the same time, we must do a good job in hygiene and regular disinfection.
