Pregnancy
After mating, doe will no longer heat, and generally can be considered pregnant. In addition, it can be seen from the appearance that the appetite of the pregnant deer increases, the sensation is getting better and better, the coat is bright, the temperament becomes docile, and the operation is cautious and secure. When the food is not eaten, the abdomen is obviously enlarged after March to April. More than 90% are pregnant. The length of the antler is related to the type of velvet deer, the sex and quantity of the fetus, the feeding method, and the nutritional level. The average number of spotted deer is 229 6 days, 231 5 days of Huaigong Lam, 228 6 days of Huaimu Lamb and 224 6 days of twins, which is about 5 days shorter than that of a single child. The gestation period of all types of red deer is basically the same. For example, there were 243 6 days for the Northeast Red deer, 244 7 days for the Tianshan Red Deer, including 245 days of the 245 days of the Huaigong Lamb and 241 5 days of the pregnant mother.
childbirth
The birth period of the deer and red deer is basically the same, generally from the beginning of May to the beginning of July, and the peak period of the child is from May 25 to June 15. The childbirth period is related to the age of the deer, the area in which it is located, or the feeding conditions. The formula for predicting the childbirth period is mainly calculated based on the date of mating and the number of days of pregnancy. Usually the deer is reduced by 4 for the allocated month and decreased by 13 for the day, and the deer's month is reduced by 4, and the day plus 1 is used to calculate the birth date.
Delivery performance: breast expansion before delivery, from the beginning of the expansion to delivery time is generally 26 6 days, 1 day to 2 days before labor, food or hunger strike, circle, looking for the location of delivery, individual deer while squeaking, frequent urination During the childbirth, egg-like mucus flows from the vaginal opening at the time of childbirth, and repeatedly climbs and stands, then discharges pale yellow water cells, and finally produces a fetus. Individually, the first deer produced a terrified quagmire and hurriedly circling or running. Most of the deer were born with their heads and two forelimbs exposed. A few deer, two hind limbs and buttocks were exposed first. In addition to the above two kinds of fetal position are abnormal fetal position, need midwifery.
Normal labor: After giving birth to doe for half an hour to 2 hours, the first production of doe is 3 hours to 4 hours.
Childbirth period considerations
The production circle needs to be clean, thoroughly disinfected before the arrival of the childbirth period, and pad clean grass. The production circle should be disinfected every 10 days throughout the birthing period.
The period of childbirth should be kept quiet, and I would not visit it.
During the childbirth period, special care should be set up, and if it is found that dystocia should be dealt with in a timely manner, it is necessary to take timely measures to find evil calf deer, and should pay close attention to the various abnormal conditions of postpartum deer, and those who are sick should be promptly treated.
A deer protection bar should be set in the lap of the lactation period.
The childbirth record should be filled in.
