When is the best mating time for gilts?
Gilts begin to show estrus (heat) when they are raised to around the fifth month. However, because gilts have only just reached sexual maturity at this time, they should not be mated. Doing so would have a great impact on the sow's later growth and development and on the survival rate of the piglets. So when raising gilts, when should they be mated? Below, the editor brings you the best mating period for gilts, let's take a look!
1. Estrus identification
Before we confirm that a gilt is in estrus, we must first do a good job of estrus identification for the gilt. This is because when a gilt reaches sexual maturity for the first time, its estrus is irregular. Under normal circumstances, it takes about three estrous cycles for it to stabilize. Normally, sows come into estrus about once every three weeks; although this is affected by local breeds, the differences are not too great. The estrus period of a sow is generally about 3-4 days. The specific estrus time will vary due to factors such as season and breed.
When checking whether a sow shows signs of estrus, we can first start from three aspects: the sow's vulva, feces, and behavioral signs. If the sow's vulva appears red and swollen, it defecates more, and it shows behavior of climbing walls and doors, then it can basically be confirmed as being in estrus. Then, when the sow's feed intake decreases, it squeals, the vulva is red, swollen and glossy, and there is mucous membrane bleeding in the vagina, then the mating work should be carried out promptly.
2. Mating identification
The mating time for sows is also very critical. Generally, within 24-30 hours after the sow comes into estrus is the best time period to mate the sow. It is best to mate the sow when it stands still. However, specifically, everyone still needs to reasonably adjust the mating time according to the breed being raised, the sow's age, and so on. If the age is relatively old, then mating should be carried out promptly on the day of estrus. If it is in middle age, then it can be appropriately delayed to the second day. Finally, if it is a young sow, then it should be carried out on the third day.
3. Post-mating management
After a gilt has been successfully mated, its movements will gradually become steady, and its feed intake will slowly rise. Management at this stage is also very important, and good feeding management and fetus protection work must be done. Control the temperature well to avoid various adverse effects on the sow from high-temperature and low-temperature environments. Ensure the sow has a suitable growing environment. In the late stage of gestation, the growth rate of the fetal pigs will accelerate somewhat. At this time, we should pay attention to appropriately increasing the proportion of nutrients in the daily ration and increasing the feeding frequency to ensure sufficient and comprehensive nutrition.
