Management of farrowing objectives to achieve optimal piglet weight at weaning (II): batches every two weeks
The dispersion of matings described in the previous article is even more drastic on farms operating in bands over one week.

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.
Lysine intake during late gestation on reproductive performance, colostrum composition, blood metabolites and hormones of multiparous sows
Higher lysine levels than those recommended by the NRC improve reproductive performance for multiparous gestating sows.
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.
Sow litter size is increased in the subsequent parity when lactating sows are fed diets containing omega 3 fatty acids from fish oil
Feeding omega 3 fatty acids as a way to increase the sows’ litter size.
Belgium: Status of sow stall conversion
Just under 36% of Flemish sow farms have so far converted, with an additional 13% having plans to do so.
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.
Thompson's tip: Keeping the milk-bar flowing
For a sow’s mammary gland to work efficiently it should have been suckled in the previous lactation, says Paul Thompson, veterinary consultant to pig-breeding company, ACMC Ltd.
Genetic and environmental effects on piglet survival and maternal behaviour of the farrowing sow
One of the key components of survival in alternative, loose-housed farrowing systems is maternal behaviour and understanding the characteristics of sows that influence survival in such environments should be an essential component when developing new breeding indices.
Oral administration of multispecies microbial supplements to sows influences the composition of gut microbiota and fecal organic acids in their post-weaned piglets
Temporal administration of probiotics to pregnant sows has clear effects on the establishment of gut microbiota to piglets after weaning.
Breeding replacement gilts for organic pig herds
In this study, breeding structures and commercial sow lines were evaluated by economic and genetic simulation studies for their suitability to provide the Dutch organic pig sector with replacement gilts.
Farrowing Monitoring (II)
A good result in stillbirths is difficult to achieve without inducing farrowings.
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.
Learning how to eat like a pig: Facilitating vertical information transfer to reduce weaning problems in piglets
The aim of this thesis was to explore whether providing piglets with more opportunities to learn from their mother about what, how and where to eat increases food intake before and after weaning and consequently can reduce health and welfare problems after weaning.
