Thirty-six Zaraibi doe goats of 3-5 years old and average live body weight (LBW) of 28.14±0.93kg were randomly distributed into three groups (12 doe goats in each) according to their LBW and reproductive status. The experimental period of does lasted for 12 months and buck treatment started two months before breeding season in September. Mating was carried out using twelve sexually mature fertile and tested bucks of 41.25±2.1 kg LBW and aged 24 months were divided into three groups receiving the same treatments of doe goats.Rocket oil (watercress oil) was received daily oral does at levels of 0, 1 and 2 mg/kg LBW for G1, G2 and G3, respectively. The results showed that the bucks in G3 showed the highest (P<0.05) scrotal circumferences (30.25 cm), followed by G2 (29.25 cm) and G1 (27.75 cm) at the end of experiment. Bucks in G3 showed the lowest (P<0.05) reaction time and abnormal sperm percentage and the highest (P<0.05) ejaculate volume, and percentages of sperm motility, and live sperm, as well as sperm concentration and total sperm output compared with G2 and G1. Fertility rate was 90, 100 and 100% for mated does and 75, 91.66 and 91.66% for all treated does in G1, G2 and G3, respectively (P<0.05). Litter size and sex ratio were the highest (P<0.05) in G3 and G2 compared with G1, while mortality rate was the lowest (P<0.05) in G3 (6.26%), followed by G2 (11.11%) and G1 (15.38%). Weaning weight, total gain and average daily gain of born kids were higher (P<0.05) in G3 than in G2 and G1. Average daily milk yield was higher (P<0.05) in G2 and G3 than in G1, being 1318 and 1426 vs. 1162 g, respectively. Percentage and yield of milk constituents were higher (P<0.05) in G2 and G3 than in G1. Only, concentration of serum albumin increased (P<0.05) with rocket oil additive as compared to G1, while the other blood parameters were insignificantly different among the experimental groups. Does in G3 showed the highest economic feed efficiency for milk production as compared to those in G2 and G1.
