It is not only related to NPDs, but it can also have a greater impact than we first thought.

The morphological differences in the cervical wall and canal between multiparous and nulliparous sows require deep AI devices adapted to the characteristics of the nulliparous.

The idea is to avoid semen backflow when we leave a catheter without its cap inside the sow for some minutes after AI.

A farrow-to-finish farm went from 10% to 50% of returns to oestrus, and almost 90% of them were regular.

We talk about weight and age at mating, stall adaptation, flushing, how to perform heat detection and insemination, the convenience or inconvenience of segregating the gilts

Joan Wennberg discusses with different experts how do they think that the ideal mating area design should be.

Weaning one or several weeks straight into pens, a week worth of space can be gained

The impact of semen used for post-cervical AI is 2-3 times bigger than that used to produce cervical insemination doses; therefore, preparation of the doses should follow an even stricter control program.

Boar exposure time, duration and frequency, proper boar: gilt or sow ratio, exposure methods, hormones, …

We recommend that producers pay more attention to gilts and sows that are at risk of increasing NPD. Situations of increased risk are described.

Production of a minimum number of doses to maintain profitability and the increase in post-cervical insemination leads to an increase of the doses produced per boar and, therefore, their share of responsibility in the production process.

The shorter and lower dose regime saves money but there is an increased risk of follicular cyst development, which may occur at doses below 13mg/day.

Introduction of post-cervical insemination has a very significant economic impact on the whole of the pork industry, and is a challenge of parallel magnitude to that raised by the transition from natural service to artificial insemination.

Meeting batch breeding targets requires availability of enough service-ready weaned sows and gilts.

This article lists the critical points that must be considered for a successful post-cervical insemination in sows.

The idea is to modify the doors of the pen where sows are housed in groups to increase the contact with the boar.
