The objective of the study was to compare growth performance, carcass characteristics, meat quality and fatty acid composition of the adipose tissue of group-penned barrows, immunocastrated boars and entire males. Furthermore, the effect of housing of entire males on the aforementioned parameters was evaluated. At 55.2 days of age, 52 Swiss Large White pigs(More)
Today, different analytical methods are used by different laboratories to quantify androstenone in fat tissue. This study shows the comparison of methods used routinely in different laboratories for androstenone quantification: Time-resolved fluoroimmunoassay in Norwegian School of Veterinary Science (NSVS; Norway), gas chromatography coupled to mass(More)
In Europe there is increasing concern about the common practice of surgical castration of piglets without anaesthesia. One possible alternative to completely avoid castration is entire male pig production. Thus, the objective of the study was to compare the growth performance, carcass characteristics, organ weights, meat quality traits, fat score and boar(More)
BACKGROUND Tannins intensively interact with rumen microbes, which is expected to have consequences for meat quality. RESULTS Silages prepared from birdsfoot trefoil (BT), sainfoin (SF), alfalfa (AF) or red clover (RC) were fed alone to 48 lambs. The SF contained five times more condensed tannins than BT, the other tanniferous plant. Growth and carcass(More)
Thirteen unilaterally cryptorchid Large White pigs, which had been immunized at 4 and 8 weeks of age and a third time at 64 ± 4 kg body weight against the gonadotropin releasing hormone with the vaccine Improvac®, were slaughtered at the age of 170 ± 9 days at a body weight of 102 ± 12 kg. Twelve pigs tested negative in the olfactory test of the salivary(More)
