In this study the effects of barren vs enriched housing conditions of pigs on their behavior during the lairage period (2-h holding period before slaughter), carcass characteristics, postmortem muscle metabolism, and meat quality were studied. The barren housing system was defined by common intensive housing conditions (i.e., with slatted floors and(More)
Three experiments, involving over 56 000 veal carcasses, were carried out to develop a method for instrumental colour classification of veal carcasses at 45 min post mortem with the Minolta CR300. The method should produce results similar to those of the 10-point colour-system, which is currently in use in The Netherlands. In the first experiment, the(More)
Pathway information provides insight into the biological processes underlying microarray data. Pathway information is widely available for humans and laboratory animals in databases through the internet, but less for other species, for example, livestock. Many software packages use species-specific gene IDs that cannot handle genomics data from other(More)
In a random selection of 480 veal carcasses, invasive measurements were made on the longissimus lumborum (LL) and biceps femoris (BF) with the Colormet, Hennessy Grading Probe (HGP4; LL only) and Invasive Meat Colour Meter. Surface colour of the rectus abdominis (RA) was determined instrumentally with the Minolta Chromameter and Surface Meat Colour Meter(More)
Improved understanding of the biology of traits of livestock species necessitates the use and combination of information that is stored in a variety of different sources such as databases and literature. The ability to effectively combine information from different sources, however, depends on a high level of standardization within and between various(More)
High quality pork is consumed as fresh meat, whereas other carcasses are used in the processing industry. Meat quality is determined measuring technical muscle variables. The objective of this research was to investigate the molecular regulatory mechanisms underlying meat quality differences of pork originating from genetically different Piétrain boars.(More)
Selection of pigs for increased meat production or improved meat quality changes muscle mass and muscle composition. This will be related to transcriptome expression profile changes in muscle tissue, generating inter-individual differences. This study investigated the differentially expressed genes in the transcriptome profiles of the longissimus muscle of(More)
With the aim of increasing the accuracy of genomic estimated breeding values for dry matter intake (DMI) in Holstein-Friesian dairy cattle, data from 10 research herds in Europe, North America, and Australasia were combined. The DMI records were available on 10,701 parity 1 to 5 records from 6,953 cows, as well as on 1,784 growing heifers. Predicted DMI at(More)
A selection experiment was carried out to study genetic and physiological factors influencing meat quality in lines of Large White pigs selected for lean (L) or fast (F) growth. Second and fourth generation pigs were used to determine effects on fibre type composition, fibre diameters and capillary density in the Longissimus Lumborum (LL). Significant(More)
