Actually, when the sow is 8-9 months old, weighs 140-150 kg, and has a backfat thickness of 20-25 mm, it is mature and has good physical fitness. breeding status. If the sow is not in normal estrus when it is 6 to 7 months old, we must take measures to achieve normal estrus and conception of the sow. We can start from three aspects: the use of pharmaceuticals, loading and transportation, and daily management to promote normal estrus of sows.
1. Use medicines
for the underdeveloped reproductive system, inflammation of the uterus, insufficiency of the ovaries, The resulting sows have irregular estrus, difficult estrus, and low breeding success rate. In this case, we can use it for sows: use Wangqing Taibao, eat one packet (100 grams) every morning, 3 days can be effective, 5 days The effect is obvious, the effect is obvious in 7 days, the estrus is obvious, and the ovulation is more. During the estrus period of the sow, use: sow Taibao, supplement vitamins and various minerals and trace elements, enhance the sow’s physique, improve disease resistance, promote fetal implantation, carry out fetal protection, and at the same time can speed up postpartum recovery, reduce Postpartum constipation without food, postpartum not in heat.
2. Shipping
For 6-month-old gilts in heat, we can Use: Loaded and transported, this method, to speed up the sow’s estrus. The specific method is: load and transport all gilts around 6 months old together, and go around the farm for a while, which can promote the first estrus of young sows. This method is suitable for sows with good physical condition and no estrus disorder, and is used for early estrus.
3. Daily management
The estrus of sows is related to the development of the reproductive system ( It can be adjusted by using medicine), and it is related to age, but also to light, temperature, nutritional status, etc. In the daily feeding process, we can increase the light intensity in the pigsty, increase the temperature of the pigsty, and supplement the protein feed in an appropriate amount to promote the sow’s estrus and conception. Be careful to control the intensity to prevent too much light, too high temperature, and excess nutrition, which will cause the sow not to be in heat.
In general, the estrus of a sow is affected by many factors, such as the development of the uterus and ovary, external stimuli, appropriate light, temperature, and nutrition. We must consider all aspects, comprehensively improve, and carry out symptomatic treatment to solve the problem.
