Abstract

On 49 brown bulls we investigated the influence of slaughter mass and daily gain from birth to slaughter on collagen traits, sensory traits, physical traits, meat colour, percentage of intramuscular fat and diameter of muscle fibre in m. longissimus dorsi. To exclude the influence of animal genotype, we included percentage of American Brown Swiss genotype and sire as a fixed effect in the analysis. Bulls were slaughtered at an interval from 501 to 658 kg live mass. Daily gain from birth to slaughter varied between 883 and 1256 g day-1, and was on average 1083 g day-1. Live mass at slaughter had significant influence on meat colour (L* value) and percentage of intramuscular fat. Meat became darker and percentage of intramuscular fat increased with increased live mass. Tendency of brighter colour and lower percentage of intramuscular fat with increased daily gain from birth to slaughter was also noted.
