The gestation period in the majority of sows is usually around 113 to 115 days. However, a percentage of sows can farrow normally up to 3 days before or after.

Aroused sows, Danish scientists have discovered, increases by several percentage points impregnation by artificial insemination. From TED Talk shared knowledge podcast.

Another convenient option for controlling the replacement entry is to incorporate the information on the breeding chart.

In the previous chapter we began to describe several systems for recording clearly and quickly the dates that gilts come into heat and for planning gilt service.

When external administration of the hormonal product is stopped, the levels of progesterone fall.

In the first part of management of the breeding chart we basically looked at how it can help us to control returns. In this second part we will look at other applications.

The mating and control unit is one of the most important elements of a sow unit. Thus, it must facilitate a high pregnancy rate, high number of piglets, uniform body condition, sow longevity and a low return rate.

So far we have seen different options for retaining the males and for stimulating the stalled sows that maximize speed and stimulus. Once stimulated, now we are going to mate them.

Different systems of boar’s retention during stimulation and mating in stalls have already been seen. Now we are going to put it into practice.

Both for heat detection and for mating, maximum efficiency is achieved if the sow is well stimulated.
