Feather pecking (FP) in laying hens may cause mortality due to cannibalism. Novel breeding methods using survival days of group-housed siblings allow for the genetic selection of laying hens with low mortality (LML: low mortality line) due to canniba

article i nfo Severe feather pecking (SFP) in laying hens is a detrimental behavior causing loss of feathers, skin damage and cannibalism. Previously, we have associated changes in frontal brain serotonin (5-HT) turnover and dopamine (DA) turnover wi

The aim was to investigate whether on-line somatic cell count (SCC) assessment, when combined with electrical conductivity (EC), should be implemented at the udder quarter or at the cow level. Data were collected from 3 farms with automatic milking s

Summary Reasons for performing study: Behavioural tests as well as observers' ratings have been used to study horses' temperament. However, the relationship between the ratings and the responses in behavioural tests has not yet been studied in detail

The first breeding value for udder health of a bull is based on the performance of his daughters in their first lactation. However, clinical mastitis (CM) is not a problem in first lactation only. Therefore, the objective of this study was to estimat

One breeding objective of Dutch cattle breeders is to improve genetic resistance against clinical and subclinical mastitis. Because of a lack of direct mastitis information, udder health breeding values are based on indirect traits. Inclusion of dire

Fokken op uiergezondheid kan betrouwbaarder, zo luidt de conclusie van nieuw onderzoek. Door de celgetalgegevens dieper te analyseren ontstaat een index met 85 % betrouwbaarheid, vergelijkbaar met fokwaarden in de zo geroemde Scandinavische landen. S

Germ-free piglets were orally infected with virulent rotavirus to collect jejunal mucosal scrapings at 12 and 18 hours post infection (two piglets per time point). IFN-gamma mRNA expression was stimulated in the mucosa of all four infected piglets, i

Uiergezondheidsproblemen kunnen ontstaan door een verstoring van de balans tussen de infectiedruk en de weerstand van dieren. Er zijn veel factoren van invloed op die weerstand, waarvan de erfelijke aanleg er een is. Fokkerij houdt zich bezig met de
