Identification of sows in estrus
The gilts usually have irregular genital irritation at 120 to 160 days of age (local pigs will be earlier) and their ovaries have a considerable degree of development but do not ovulate. The first ovulation is puberty, which marks the sexual maturity of the gilt, but the number of ovulation during the first estrus is small, and the development of other organs and tissues of the body is not fully mature, so it should generally be the second or third. When the estrus is mated, the sow’s weight should reach 110-120 kg. Timely mating is one of the important measures to increase the number of litters in the first sow. The average estrus cycle of gilts after puberty is 21 days. The duration of estrus is generally 3 to 5 days. The estrus cycle of the same species of young sows is shorter than that of the sows. The estrus time of sows after weaning is related to the number of litters, breast-feeding time, and sow's sensation. Generally, estrus symptoms occur 3 to 5 days after weaning. If it is extended to more than 2 weeks, it is called post-weaning. When the sow starts estrus, excitability gradually increases, restlessness, ambulation, frequent urination, decreased appetite, slight redness of the vulva, and a small amount of transparent mucus, after the sexual desire is strong, climbs the fence, climbs other sows, or accepts other sows Climb and automatically approach the boar. When the pus is swollen and reaches a peak, a thick white silky mucus flows out and the sow's waist is pressed firmly. The posture of standing still, ears stand, and the tail is upturned.
