Results and DiscussionLive-body weightThe average live-body weight, heart girth andbody length measurements for growing calves andadults are shown in Tables 1 and 2 respectively.Analysis of variance revealed a significantdifference (P < 0.01) in live weight between sexesin all ages and between intact bulls and castrates.Birth weight averaged 26.8 kg in male and 15.5 infemale calves. Mature weight was 146.4 ± 19.3 kgin cows, 292.8 ± 31.6 kg in intact bulls and 306.8 ±31.3 kg in castrates.Heart girth and body lengthHeart girth and body length measurementsshowed significant differences (P<0.01) betweensexes and between intact bulls and castrates.However, these differences were not detectedamong growing calves. The average heart girthestimates for mature cows, intact bulls andcastrates were 246.5 ± 219 cm, 152.5 ± 8.6 cm and
