Benefits of novice breeders: rapid identification skills for successful conception of sows!
If we can judge early that the sow has become pregnant, we can take corresponding measures and corresponding management to avoid accidents, and if we are not pregnant, we should strictly urge the sow to mate again to prevent it from becoming an empty sow. It is necessary to understand how the sow is conceived successfully, and many novice breeders do not know it.
1. Early diagnosis
On the appearance, the coat color is shiny, the eyes are bright, and the cracks under the vulva contract upward to form a seam, which means conception.
2. Iodination method
Take 10 milliliters of sow urine, drop it into the iodine gas lamp, or heat it on the alcohol lamp. When the urine reaches the boiling point, it appears red, which means conception! If there is a light yellow or brown color, it means that you are not pregnant!
3. Finger pressing method
3-4 days after breeding, the sows gently pinched the last two pairs of nipples with their hands and found a hard milk duct, indicating conception.
4. 18-24 days after mating, there is no estrus, the appetite increases sharply, there is no material left in the trough, and the abdomen increases gradually, indicating conception.
5. Using pregnancy tester to determine 25-30 days after mating, the accuracy can reach 98% 100%.
6. 30 days after mating, the nipple of the sow is black, and the attachment of the nipple is a black-purple halo indicating that it has become pregnant.
7. Gluttonous, sleepy, fast recovery, gentle temperament, careful action, bright fur close to the body, gradually enlarged abdominal circumference, dry vulva, forming a seam, tail drooping
8. 1 ml of hexene estradiol powder was injected into sows 16-18 days after mating.
