摘要：

Twenty Ile de France ram lambs were allocated to two groups following weaning. One group (n=10) was treated weekly with an intramuscular injection of an anabolic steroid (50 mg nandrolone laurate) for a 12-wk period. The other group (n=10) served as a control. Treatment with an anabolic steroid did not significantly increase mean shoulder width (22.8 vs. 22.0 cm), shoulder height (61.7 vs. 60.8 cm), body length (72.8 vs. 70.2 cm) and body weight (42.5 vs. 39.8 kg). Scrotal circumference and testes volume were significantly (P< 0.01) less in the treated group, a decrease of 24.5 and 51.2%, respectively. No significant differences were recorded in feed conversion rate (6.15 +/- 1.36 vs. 6.28 +/- 1.44) and serum testosterone concentration (1.67 +/- 5.19 vs. 1.85 +/- 3.88 ng/ml) for the treated and control groups, respectively. Although use of the anabolic steroid in young ram lambs did not result in a significant increase in muscle deposition, the androgenic effect retarded testicular development and could possibly affect the future reproductive performance of the ram.
