(A) Pre-preparation work for the farrowing period The gestation period is about 60 days. Generally, the clean-up, disinfection and heat preservation of the maternal box should be completed within 5 to 10 days before the childbirth. The chamber disinfection can be scrubbed with 2% alkaline water, and can also be flame sterilized with a torch. The mat grass can be used for soft, easy to break, strong insulation properties of mountain grass, soft straw, soft weeds and so on. How much grass can be controlled according to the temperature, northern cold regions can be more than a few. In addition to the insulation effect of bedding, but also conducive to Aberdeen Baotuan and sucking milk, is conducive to combing plush. Therefore, even if the air is warm, it should be added. The bedding should be swift enough before the farrowing, otherwise the temporary replenishment after the lack of grass will make the mother beggar apprehensive. The gestation period of raccoon is relatively accurate. The method for calculating the expected date of birth is as follows: The expected date of the maternal cub that is mating in February is 2 months plus 2 days. If the maternity period for February 8 is February + 2 = April, the date is not Change to 8; the expected date of birth is April 8th; the expected date of mating in February of the following year is 2 plus 2 and the date is reduced by 1. For example, the due date for delivery on February 8 is February + 2 = April, and the date minus 1 is 8-1. =7, the expected date of birth is April 7. The expected date of mating in March is 2 plus 2 and the date is 2. For example, the expected date of delivery on March 8 is March + 2 = May, and the date is 8-2 = 6. It is May 6. For example, females mated on March 1-2, the expected date of birth is month plus one, and date plus 28, such as the month of March 2 plus 1 equals 4, the date plus 28 equals 30, and the expected date of birth is April 30. . (b) Treatment of childbirth difficulties When the child's childbirth has appeared on the childbirth signs, she has not seen the child's child. The mother/family frequently enters and exits the room and is panic-stricken. She looks back at the abdomen and has painful symptoms; she has seen the amniotic fluid flow out of the baby or the fetus. At the reproductive hole, there is a possibility of dystocia. When dystocia is found and it is confirmed that the cervix has been opened, 0.2-0.5 ml of posterior pituitrin or 2-2-3 ml of intramuscular oxytocin can be injected intramuscularly. If the fetus is still not seen after 2 to 3 hours, artificial midwifery can be performed. The method is to first disinfect the genital area with a disinfectant solution, and then lubricate the vagina with glycerin to pull out the fetus. When oxytocin and midwifery are not effective, a caesarean section may be performed to save the mother and the fetus. (C) postpartum check to take "listen, see, check" a combination of post-natal check. "Listening" means listening to Auntie's cry. "Seeing" means looking at the mother's food, feces, nipples, and activities. If Aberdeen seldom barks, the sound is loud and short, and the mother’s appetite is getting better and better. Her nipples are full and her activities are normal. This shows that Aberdeen is healthy and well developed. "Check" is to open the chamber and check the baby directly. The method is: first to entice or drive out of the mother cubs, close the door and check. Healthy Aberdeen huddles in a nest, grows evenly, becomes full-bodied, dark-skinned, warm-hearted, and is struggling with strength in their hands. On the contrary, if the youngsters crawl around in their nests, their hair is wet, their bodies are cooler, and their energy is weak, it is unhealthy. The first postpartum examination should be performed 12 to 24 hours after the farrowing, and the subsequent examinations should be based on the hearing and seeing. It is generally better to check less. However, when the mother-in-law was found not to be caring for the young, she must be promptly inspected and found that the problem was solved in a timely manner. When inspecting Tsai, workers are advised to wear a pair of gloves or a small room to pick up their hands before picking them up so as to avoid offensive odors on the body and cause disgust on their mothers. Sometimes, due to improper inspection, the staff may feel uneasy. When there is a chaotic run, it should be carried into a small room. After closing the door for 0.5--1 hours, I heard that the cockroach in the crate was quiet and opened the door of the room. (D) Postpartum care mothers mothers are very strong. Aberdeen mothers are mainly nursing care and relying on breastmilk growth. Therefore, ensuring that breastfeeding is the key to improving the survival rate. Normally, the plush around the mother's nipple should be pulled out in time to facilitate milking. In the event of a mother's lack of milk or lack of milk, she should promptly transfer her baby to other mothers. On behalf of the mother-in-law should have more effective nipples, adequate milk, strong maternity, the date of birth is the same as or similar to the foster beak, and the size of the beak is similar. When the foster mothers are released, they will be kept in a small room and painted on the deceased sister-in-law with the feces and urine of the foster mother, or wiped in their nests and placed in the entrance of the cell. The darling will be housed inside. It is also possible to place the foster aviary directly into the foster mother's nest. Observe for a period of time after fostering. If the mother-in-law does not accept the foster child, she will need to change her mother's son to a new generation. Aberdeen can also be fed with litters, mother cats, and female foxes. It can also be fed artificially to feed them. During the entire period of breastfeeding, close attention must be paid to the growth and development of Aberdeen. When the growth of Aberdeen is slow or stagnant, it means that breast milk is insufficient or poor quality. (5) Aberdeen feeding and fast-growing A. trifolii grow rapidly, and generally begins to eat at 3 weeks of age. Individuals can be fed separately with easily digestible congealed feed. If you don’t eat the feed, you can stick it to your mouth or put it on your mouth and train it to learn to eat. At the age of 45--60 days, most of the young people can eat and live independently, and should be weaned at a proper time. If the growth and development of Aberdeen is good, the size of Aberdeen is even, and all the mothers can be separated at one time. Just like the number of litters in a litter, the development is not balanced, and weaning should be done in batches. The strong youngsters will be separated first, and the weak ones will be left to their mothers for a period of time, and they will be separated after another.
