Pig breeders in the past have adopted their breeding goals according to the needs of the producers, processors and consumers and have made remarkable genetic improvements in the traits of interest. However, it is becoming more and more challenging to

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. Sow and litter performance from over 2000 cros

For many years, there has been debate about the suitability of traditional and conventional pig breeds in low-input and organic production systems. This review compiles reproductive and finishing performance of traditional and conventional breeds in

The potential of near-infrared spectroscopy (NIRS) measurements early post mortem was investigated to predict ultimate drip loss, colour, tenderness and intra-muscular fat of pork. Three locations (M. longissimus thoracis, M. longissimus lumborum and

Increased interest in transfer of valuable genetic material around the world with minimal health risks has stimulated the development of non-surgical embryo transfer (nsET) technologies in pigs. Experimental evidence shows that nsET without sedation

The present study describes algorithms for identifying errors in feed intake data of pigs, recorded with singlespace computerized feeding stations. Potential causes of errors are failed identification of pigs or an incorrect recording of feeder weigh

Data of the Dutch herdbook breeding programme and data obtained in an experimental progeny test of AI boars under commercial fattening conditions were used to estimate the genetic correlations between traits measured in central test and on-farm test

Environmental effects were investigated and genetic parameters estimated in central test results from Dutch Landrance and Dutch Yorkshire pigs, tested on two stations under a restricted feeding regime. To investigate the environmental effects within

In this first paper of a series, Dutch central test results are examined for genotype × environment interaction (G × E) and the data are further used to estimate genetic correlations between the various evaluations of growth and carcass quality, as
