TI Physiological Stress Measurement During Slaughter In Calves And Lambs

QU Journal of Animal Science 1976; 42: 831-7

PT journal article

AB Heart rate in calves was significantly (P<.05) affected by age, whereas in lambs heart rate was affected to the same extent by method of restraint with the shackled animals having the highest values. Respiration rate in calves was affected significantly (P<.01) by age, restraint and their interaction, although in lambs respiration rate was only affected (P<.05) by stunning. Furthermore, rectal temperature was only slightly affected (P<.05) by age in calves and not affected in lambs. The carcass pH in both species groups was affected (P<.05) by age and restraint in calves and weight and immobilization in lambs. Additionally, age, weight, restraint and immobilization influenced the tenderness of the longissimus (P<.01) and quadriceps femoris (P<.05) muscles in the calves and the cooking losses of the leg steak and rib chop in lambs.
