Abstract:
The influence of a growth promoter on preweaning growth of beef steer calves in the Kalahari thornveld and shrub bushveld was investigated. Calves (n = 40) implanted with a testosterone propionate-oestradiolbenzoate compound at an average age of 120 d, attained a higher (P < 0,005) weaning mass (256,7 vs 239,1 kg) and superior gains (93,9 vs 79,9 kg) over the trial period than the control group (n = 40).
