TOPIGS research: SNPs for more uniform and bigger litters found
TOPIGS researchers have found a series of SNPs that define a genetic region which explains genetic variation for litter size and uniformity between litters.

Stillbirth and preweaning mortality in litters of sows induced to farrow with supervision
To evaluate the benefits of induced farrowing with supervision on rates of stillbirths and preweaning mortality,a total of 159 multiparous sows were assigned in approximately equal numbers to two groups.
Hormone management V: Using altrenogest to restore the metabolic state of weaned sows
When gilts were mated at a little more than 100 kg, productivity at 2nd parity had a huge decline and the sow was never able to reach their maximum potential.
Replacement planning and altrenogest management using spreadsheets
In the last chapter on hormone management we looked at the advantages of “a la carte” altrenogest treatment as opposed to the 18 day treatment used to synchronize gilts.
Seasonal effects on oocyte developmental competence in sows experiencing pregnancy loss
The aims of this study were to determine whether WSI and season are associated with changes in oocyte developmental competence in sows experiencing early and late pregnancy loss.
Management of hormones (IV): Using altrenogest
In this chapter the use of progesterone derivatives to modify the duration of estrus in sows is explained.
JSR open 900 sow joint venture in China
A lavish ceremony, attended by over 150 dignitaries, celebrated the opening of The Hubei Liangyou JSR Breeding Limited, a new Chinese joint venture between JSR Genetics and state-owned Hubei Liangyou Livestock & Poultry Company on the 18th of October, 2011.
Researchers identify genetic traits in pigs to help deliver tastiest meat
Irish researchers have identified genetic traits in pigs that can be used to ensure the tastiest, healthiest pigmeat is delivered to consumers.
Canadian institutions partner to invest $20m in livestock genomics research
Genome Alberta announced today that it is leading a group of funding partners on two large-scale genomics projects which will help improve Canada’s livestock sector. These projects build on Genome Alberta’s Applied Livestock Genomics Program which was launched in Dec 2010.
Farrowing Monitoring (II)
A good result in stillbirths is difficult to achieve without inducing farrowings.
Clinical case: Altrenogest for the prevention of premature farrowings
The farm, with an elevated number of animals, had been experiencing for several days an increased number of births in gestation on the weekend before moving the sows to the farrowing pens. Mortality in these births was 100%.
Use of betaine in gilts and sows during lactation: effects on milk quality, reproductive parameters, and piglet performance
Treatment with betaine improve reproductive performance of gilts and sows, and increase body weight gain of the piglets.
TOPIGS genetics to Vietnam
De Heus Vietnam will distribute these genetics on the Vietnamese market.
Monitoring farrowing (I)
In this chapter we will present the farrowing stages and how to control it.
Stimulation during insemination: The Danish perspective
In Denmark the most common practice is to always stimulate with the boar together with a complete 5 point pattern of stimulation carried out by the inseminator.
Incidence and prevention of early parturition in sows
The administration of altrenogest in late gestation is an effective and safe method to prevent early parturition and can counteract the reproductive losses because of premature farrowing, which may occur in a substantial part of the farrowing events.
