The information did not significantly affect the hedonic scores. The percentage of dislikes was very low, i.e. 3 vs. 6% (p = 0.24) for salami LOW and HIGH, respectively.

The chicks were fattened until day 35 and then slaughtered. The effect of treatment, time, and sex and their interactions on carcass and meat quality traits were determined. No significant impact of the \"treatment time\" was analysed, but \"treatment\" and \"sex\" and their interactions influenced (P < 0.05) the different parameters. After hatching, group L broilers were heavier (P < 0.05), followed by slower growth compared to group H chicken. At slaughter day, body, carcass, and leg weights of group H broiler were higher (P < 0.05) and yield results lower (P < 0.05) compared to group L animals. pH, drip loss, shear force, and lightness values of group H broiler breast muscles were higher (P < 0.05) and grill loss and redness values lower (P < 0.05) compared to group L Musculus pectoralis superficialis (MPS). Body, carcass, MPS, and leg weights, leg yields and grill loss and lightness values of the male broiler were higher (P < 0.05) and drip loss results lower (P < 0.05) than the female birds. Male group H broiler showed lower (P < 0.05) carcass and MPS yields compared to the control and group L males, whereas females group H birds had higher (P < 0.05) carcass and MPS weights and lower leg yields (P < 0.05) than the female group L animals. The study shows that an increasing incubation temperature during early embryogenesis positively influences the growth and carcass traits of the broilers, accompanied with a partly negative impact on meat quality (drip loss, shear force, lightness).

Homozygous naked neck (NaNa) broilers, which possess a higher adaptation to heat due to a reduction of feather coverage, exhibited higher growth rates and meat yield. This study was conducted to investigate the influence of genotype x temperature interactions on the reproduction traits of heavy broiler dams caused by different feathering genotypes induced by naked neck gene (Na). In an additional experiment, the effect of Na gene on embryonic activity using oxygen uptake was examined. Normal-feathered (nana) and NaNa hens were maintained in separate cages under high (30 degrees C) and moderate (19 degrees C) temperatures, with RH of 55% from the 18th to 72nd week of age. Egg production, fertility, hatchability, and the time of embryonic mortality were recorded. In comparison with the NaNa genotype, the nana hens showed clear performance depressions under thermal stress with respect to egg production (63%), fertility (20%), hatchability, and number of chicks (72%). Under temperate ambient temperature, there were no differences in laying performance and fertility between both genotypes, with the exception of hatchability due to an increase in embryonic mortality as a result of the Na gene and consequently in the complex trait number of chicks. The early embryonic mortality of eggs laid by nana hens exposed to heat stress is clearly higher than of eggs by nana hens kept under temperate ambient temperature. In contrast, there were no significant differences in early embryonic mortality of eggs of NaNa birds kept under high and temperate environmental temperatures, demonstrating that heat stress leads to reduced early embryonic livability. Embryonic mortality in the late developing stage is significantly increased, and the homozygous genotype is much more affected than the heterozygous embryo. The possible reason for the Na gene-induced embryonic mortality is still not clear.

To get a genetically smaller minipig, a new breeding scheme with a focus on weight reduction has to be developed. Therefore, 19 505 body weight measurements of 3461 Goettingen minipigs were analysed with multiple trait models and random regression models (RRM) for the estimation of genetic parameters. Heritabilities were moderate with slightly higher values estimated with the RRM. Genetic correlations between body weight measurements at different ages were decreasing with increasing time lag between the measurements. An operational breeding goal for relative weight reduction RWR is suggested in which the weight reduction in each age class is expressed as per cent of the actual body weight and is weighted according to the proportion of animals sold in this age class. Expected genetic progress was calculated for two different selection ages (80 and 150 days). Selection at age 150 days leads to an expected genetic progress of 3.9 % RWR per year. And it is shown how the selection for RWR will modify the shape of the growth curve.

For animal welfare reasons, castration is announced to be banned in the European Community. This study aimed to investigate whether androstenone, skatole and indole in backfat of boars may be reduced by different scalding technologies. To discriminate ante and post mortem effects, carcasses were sampled before and after scalding in two abattoirs using either horizontal (TANK) or vertical (TUNNEL) scalding. Backfat samples were analysed using gas chromatography (androstenone) and liquid chromatography (skatole, indole). Neither TANK nor TUNNEL scalding did significantly reduce malodorous compounds. Skatole and androstenone in backfat obtained after scalding averaged 112 +/- 123 ng/g and 1196 +/- 885 ng/g melted fat, respectively; significant differences between abattoirs were observed for skatole. Increased skatole levels were tentatively assigned to longer transport duration. Concluding from recent consumer research and subsequent application of suggested sensory rejection thresholds for androstenone (2000 ng/g) and skatole (150 ng/g), nearly 30% of the carcasses may be unacceptably tainted.

Additionally, the type of discharge showed interactions with the parity and the smell of the discharge, as more animals with fetid and purulent discharge and more animals in the first lactation with a purulent discharge developed ovarian cysts.

Estimation of (co)variance components was carried out using multivariate animal model. From the traits recorded at licensing. live weight, followed by type traits of conformation and muscle mass, had the highest impact on the auction price. Also the effects of breed, PrP (Prion Protein) genotype, and owner of the ram influenced the auction price of rams significantly. A moderate genetic contribution of auction price, with favourable genetic correlations to all collected performance traits (average daily gain from birth until licensing, muscle depth, fat depth, conformation, muscle mass and wool quality), was estimated.
