Nutritional value of Dorper (n=10) and Merino (n=10) by-products were evaluated. Proximate composition differed between organs and breeds with Merino heart (68.9 g/100 g), spleen (77.2 g/100 g) and testicles (83.7 g/100 g) having higher moisture contents than their Dorper counterparts. Dorper brain (10.1 g/100 g), heart (15.2 g/100 g), spleen (20.4 g/100 g)(More)
The meat quality of kudu and impala was compared. Live weight and carcass weight differed between species, genders and age groups. Impala had the highest dressing percentage while kudu had the highest live weight and carcass weight. Kudu had the lowest fat content while female animals had a higher fat and myoglobin content than males. Sub-adults had a(More)
Game meat has distinct sensory characteristics and favourable fatty acid profiles which differ between species. The SFA's percentage was found to be higher in impala meat (51.12%) than kudu meat (34.87%) whilst the total PUFA was higher in kudu (38.88%) than impala (34.06%). Stearic acid (22.67%) was the major fatty acid in impala and oleic acid in kudu(More)
Cropping methods that induce the least amount of stress are key in ensuring acceptable meat quality from wild ungulates. The purpose of this study was to compare the effect of day and night cropping on the quality of Red Hartebeest (Alcelaphus buselaphus) meat. Ten animals were cropped during the day and ten at night. Emphasis was placed on ultimate pH(More)
OBJECTIVE The combination of butorphanol, azaperone and medetomidine (BAM) with subsequent antagonism by naltrexone-yohimbine or naltrexone-atipamezole was evaluated for reversible immobilization of captive African lions (Panthea leo). STUDY DESIGN Prospective, clinical trial. ANIMALS Twenty lions, 11 males and nine females, weighing 38-284 kg were(More)
This study compares the effects of day- and night cropping on the quality of gemsbok meat. Day-cropped animals had higher behavioural scores and cortisol levels (behavioural score: 3.5+/-0.423; cortisol: 136.88+/-2.731nmol/L) than night-cropped animals (behavioural score: 2.1+/-0.378; cortisol: 64.1+/-1.633nmol/L) while night-cropped animals had a higher(More)
The study investigated the effect of a slow-release formulation of zuclopenthixol acetate (Acunil®) on blue wildebeest ( Connochaetes taurinus ) in captivity. Two groups of trials were conducted using either Acunil or a placebo (control). Animals (Acunil: n = 17; placebo: n = 12) were observed for a 12-hr period before the administration of Acunil or the(More)
We fitted two blue wildebeest (Connochaetes taurinus) with modified versions of the Equivital™ EQ02 wireless monitoring system to evaluate if the device could accurately measure heart rate and respiration rate in this species whilst anaesthetized as well as whilst fully conscious in captivity. Whilst under anaesthesia, we monitored each animal's heart rate(More)
