20 years ago we inseminated gilts when too small, then we inseminated them when too heavy, and now we are returning to an intermediate weight.

Encapsulation allows to reduce the dose per sow and a sequential release of sperm.

As you probably know, the name pig333 web comes from the length of the sow's gestation, which is "3 months, 3 weeks and 3 days". This paper proposes the necessity to review the length of gestation on our farm.

The goal is to know the production stage of gestating sows in a quick and visual way.

These tests have several practical applications, as the detection of boars that are linked to the appearance of hernias or the susceptibility towards certain enteric diseases or even syndromes like the PFTS.

Achieving a high prolificacy and knowing how to take advantage of it (transform it into weaned piglets) is vital for the productivity of a sow farm.

The use of these nests help create two well-differentiated areas: a warmer one for the piglets and a cooler one for the sows.

The veterinarian is called from a new established herd in Brittany because some clinical signs appear on gilts from the two first deliveries introduced in the farm.

We should be cautious when setting the number of sperm per insemination dose, so the urge to reduce it does not make us use a number that is under the fertility threshold. Something that may be productive and/or profitable for a certain farm may not be so for another farm.

The results reveal that the stress that the sows due to excessive interventions around the moment of the farrowing causes a clear increase in the pre-weaning mortality.

We saw aggressiveness in the sows, and we suspected that it could have been caused by the handling around the moment of the farrowing. We decided to register and analyze the data relative to the handling in order to confirm our suspicions.

The procedure is simple, quick and well tolerated by the recipient sows.

It is common to see that there are many farms on which the gestation of the sows entered in the farrowing quarters is not correctly managed. How much space / batch would be losing a farm that enters systematically a 10% of sows / batch one week before than the appropriate date?

There is an unusual increase of the returns-to-oestrus at 31-39 days. The majority are due to sows previously negative to the pregnancy ultrasound testing, and the returns-to-oestrus happened before 42 days.

Clinical disease and outcome following PRRS infection has significant inherited components.

The use of two different feeds for the sows in the farrowing quarters is not always easy at a logistical level.
