PIC Implements Imputation of Selection Candidates
PIC is pleased to announce the continued acceleration of genetic improvement by successfully developing and routinely implementing imputation of 60K SNP genotypes for nucleus selection candidates.

Effect of nutrition on boar semen quality
Boars need to be treated as individuals and fed accordingly. It is advisable to weigh the boars frequently to maintain the correct plane of nutrition.
PIC and GreenFeed set sights on market leadership in Vietnam
A year on from reporting its tie-up with local agribusiness powerhouse, GreenFeed, for the production and distribution of genetically advanced swine semen in Vietnam, PIC announces that the scope of the cooperation has been expanded to embrace the development of a complete breeding pyramid. A new company, GreenFarm, has been registered.
Efficacy of the anti-GnRF immunization closer to slaughter
The secondary immunization can be moved closer to slaughter, while still limiting the incidence of boar taint.
Developmental factors that influence sow longevity
Those factors that were significantly associated with longevity, regardless of definition, were age at first farrowing, litter size at first farrowing and last farrowing...
FCR TOPIGS finishers improves by 0.07
Pig farms with TOPIGS finishers realised a FCR of 2.55 in 2011. In addition to this the growth per day rose by 5 gram to 811 gram and the meat percentage rose by 0.5%
Intrauterine growth retarded progeny of pregnant sows fed high protein:low carbohydrate
Dietary protein:carbohydrate ratio of the diet may affect fetal growth sow’s during pregnancy.
Effects of altrenogest treatments before and after weaning on follicular development, farrowing rate, and litter size in sows
The different altrenogest treatments before weaning did not prevent the growth of follicles before weaning and similarly affected subsequent follicle development and fertility.
Hypor first to market with Genomic Selection
Hypor today announced its first-to-market full Genomic Selection breeding program that enhances accuracy in genetic selection for pig breeding.
Thompson's tip: Boar stimulation
For optimum results, producers should organise their work so that once stimulated by the boar all the stimulated sows can be served within a 20-minute period.
Litter size at nursing and maternal parity did not affect future fertility in the gilt
14.7 total born piglets were found both in gilts that were nursed in litters of 9 and of 13 piglets.
Revealing genetic relationships between compounds affecting boar taint and reproduction in pigs
The main goal of this study was to investigate the relationship between genetic factors involved in the primary boar taint compounds in an attempt to discover ways to reduce boar taint without decreasing fertility-related compounds.
Sow feeding management during lactation (1/2): Feeding during previous gestation
Today sows have a milk production of 8-12 liters/day or more. The challenge of feeding the lactating sow is not new and improvement to the genetic potential of lean and prolific dam lines make this issue of critical importance for any breeding herd.
Effect of parity and number of suckling piglets on milk production of sows
On average, milk production reached 10.7 kg/day.
Anoestrus upon weaning
Short weaning to service interval isn’t always a synonym for good management, since we have to take into consideration not only average number of days, but also the effect on the percentage of distribution after returns.
