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.
Top Chinese talent joins JSR
One of China’s brightest young graduates has joined a leading UK pig genetics company and will play a key role in their plans for sales growth in China and Asia.
Vulvar skin temperature changes significantly during estrus in swine as determined by digital infrared thermography
This study demonstrated that VST of sows and gilts, measured by IRT, changes significantly during estrus. The potential to use digital infrared thermography as an adjunct tool during estrus detection in swine appears to be promising.
Thompson's tip: Combating seasonal infertility
Many farms will experience reduced fertility over the next few months due to summer and autumn infertility, warns Paul Thompson, veterinary consultant to pig-breeding company ACMC Ltd.
Foundations for optimizing lactation
The milk production of sows is one of the parameters that has evolved the most over the last several decades.
Farrowing induction IV: Guidelines
In this chapter we will take a look at some other aspects of farrowing induction...
Genetic defects of the skin
The most relevant genetic defects of the skin are epitheliogenesis imperfecta, pitryisis rosea and malignant melanoma. Recent data suggest an increase of the melanoma incidence in Duroc bred, incidences of 2.60% and 0.62% have been found in two Duroc nucleus herds.
Managing a 3-week batch system, weaning at the beginning of the week
This may be a good option when farrowings and litter control during the first days are the priority.
Luteinizing hormone secretion as influenced by age and estradiol in the prepubertal gilt
The aim of this study was to determine if there is an age related reduction in the sensitivity of the negative feedback action of 17β-estradiol (estradiol) on luteinizing hormone (LH) secretion in the prepubertal gilt.
Managing a 3-week batch system
On small farms it is better to group tasks on specific days, leaving other days with less tasks in order to organize days off...
Analysis of water, feed intake and performance of lactating sows
An enhanced feed and water intake during lactation may increase weaning weight of piglets and decreases relative body weight loss of sows.
Interaction of zearalenone and soybean isoflavone on the development of reproductive organs, reproductive hormones and estrogen receptor expression in prepubertal gilt
The aim of the present study was to investigate the interactive effect of zearalenone (ZEA) and soybean isoflavone (ISO) on the development of reproductive organs, reproductive hormones and estrogen receptor expression in prepubertal gilts.
