Fetal palpation is the most common diagnostic method for determining whether a breeding female is pregnant. Fetal touch inspection is easy to operate, with high accuracy, and is proficient in touch fetal technology. It is possible to make targeted preparations for nutrition, fetus protection and delivery of pregnant female rabbits, and timely replenishment of empty pregnant female rabbits to improve the reproductive rate of female rabbits. , increase the efficiency of raising rabbits. The techniques are as follows:
1. Time to touch the fetus The fetus should be touched 8 to 10 days after the female rabbit is bred, and the inspection should be arranged during the fasting time of the female rabbit. Beginners lack understanding of embryo and fetal position, so it can be done 12 to 14 days after mating of female rabbits to facilitate accurate identification.
2. When touching the fetus, first place the female rabbit to be checked on a flat plate or the ground, or it can be carried out in a rabbit cage, with the head of the rabbit facing the examiner, and one hand holding the female rabbit The rabbit's ears and neck skin are well secured, the other hand makes the thumb and the other four fingers form an eight shape, the palm is upward, stretched out under the female rabbit's abdomen, gently hold up the hind abdomen, and move the abdominal contents forward , slowly close the five fingers, and touch the shape, size and texture of the abdominal contents. If you touch the abdomen as soft as cotton, it means that there is no pregnancy; if you feel the meat balls the size of peanuts one by one, the meat balls can slide and be rich. Elasticity, which is the fetus, indicates that the doe is pregnant. During the inspection process, the number of pregnancies of individual female rabbits is often small. During inspection, it is necessary to repeatedly touch from front to back to detect the embryos.
3. Precautions for membranous embryos First, touch the embryo in the early stage. Beginners may easily confuse the 8-10-day-old embryo with the fecal ball. The fecal ball is mostly round, with a smooth surface, no elasticity, and an abdominal cavity. The distribution area is large, there is no certain location, and it is connected with the rectal fecal bulb. The position of the embryo is relatively fixed. Gently squeeze it with your hands, the surface is smooth and elastic, and it is easy to slide when you touch it. Second, the movements should be light when touching the embryo. Do not squeeze or count the embryos with your fingers, so as to avoid miscarriage or stillbirth. Fetal rabbits the size of egg yolks can be touched in 15 days, and the breasts of the female rabbit can be found to be swollen in 24 days, and the abdomen is large and sagging. Breast milk begins to produce cubs in about 30 days.
