Sow overmanagement consequences (2/2)
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.

Sow overmanagement consequences (1/2)
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.
Non-surgical pig embryo transfer is a reality
The procedure is simple, quick and well tolerated by the recipient sows.
Colombia and Canada reaffirm sanitary and phytosanitary agreements
During the committee, punctual agreements were established in order to make progress in the importation of animals and genetic material of the swine and ovine species.
Do we make the most of the space in our farrowing quarters?
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?
Clinical case: High percentage of returns-to-oestrus and of sows negative to the pregnancy ultrasound testing
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.
Maternal perinatal transfer of vitamins and trace elements from sows to piglets: more than an iron deficit?
New neonatal strategies of micronutrient supplementation to piglets may be required nowadays.
Pen housed sows with electronic feeding stations
Stage of gestation is the critical point when the sows in a pen with electronic feeding system.
The role of host genetics in the response of pigs to PRRSV infection
Clinical disease and outcome following PRRS infection has significant inherited components.
Use of special diets during the pre- and postpartum periods
The use of two different feeds for the sows in the farrowing quarters is not always easy at a logistical level.
A simple novel measure of passive transfer of maternal immunoglobulin is predictive of preweaning mortality in piglets
The Ig immunocrit method is a simple and useful in assessing the initiation of colostrum and the nursing ability of sows, and the effect of these events on preweaning piglet mortality.
Use of special diets during the weaning-to-service interval
The weaning-to-service interval is a short but vital period regarding the productivity of the sow.
Reproduction in gilts inseminated with PCV2-spiked semen. Protection by gilt vaccination with a sow PCV2 vaccine
PCV2 vaccination of the gilts prior to insemination with PCV2 spiked-semen showed a clear decrease of viral load in the gilts as well as a much lower viral excretion that were compatible with foetus protection.
TOPIGS starts to banish boar taint from dam lines
TOPIGS has started to breed sows that produce offspring with less boar taint.
Microbiological, pathological and histological findings in four Danish pig herds affected by a new neonatal diarrhoea syndrome
The results of the study supported the hypothesis that a new neonatal porcine diarrhoea was present in the investigated herds.
When will genomics deliver?
Does the complexity and expense of genomics mean that it will only be available to the major global pig breeding companies in the future? If the price of genotyping continues to reduce, it may be possible for medium and smaller size breeding companies to share funding and identify desired genotypes.
