This study was planned to investigate the effect of Berberis lycium on theperformance of broiler chicks. Six experimental rations designated as A, B, C, D, Eand F having 0, 0.5, 1.0, 1.5, 2.0 and 2.5% B. lycium were fed to 240 broilerchicks, randomly distributed into 24 replicates, so as to have 4 replicates pergroup and 10 chicks/replicate. The experiment lasted for 35 days. Average weightgain, feed consumption, feed efficiency, dressing percentage, mortality and weightof visceral organs, breast and thigh were use (criteria of response. Mean bodyweight gain / chick were 1403.9, 1424.7, 1429.3, 1438.4, 1486.1 and 1404.2 g forgroup A, B, C, I and F respectively. Though the differences in body weight gainwere statistically non significant yet apparent body weight gain quite high ingroup E (1486.18) as compared to the control (1403.98). The increased body weightgain in group E increased gross return by Rs. 3.8 per bird as compared to thecontrol. The average feed consumption per chick was 3296.2, 3165.4, 3134.3, 3123028.0 and 3165.9 g for group A, B, C, D, E and F respectively. Non significantdifferences were revealed in mean feed consumption. However, numerically feedconsumption was lowest (3028.Og) in group E as compared to the control (3296.2).The lower feed consumption resulted in saving of 268.28 of feed / chick in groupE as compared to the control which amounted to a saving Rs. 3245.6 / 1000broilers in feed cost. Feed efficiency (feed/gain) was 2.4, 2.2,
2.2, 2.2, 2.0 and 2.3for group A, B, C, D, E and respectively. Statistically the differences were nonsignificant, however, numerical differences were important from economic pointview. The feed efficiency was most favourable in group E. Mean dressingpercentage, weight of breast and thigh were not significantly influenced by B.lycium. Average dressing percentage was 57.0, 57.1, 57.76, 57.6, 58.1 and 57.1, meanbreast weight was 24 266.0, 247.2, 256.7, 277.0 and 267.6 g and mean thigh weightwas 123.6, 127.0, 120.2, 128.1, 138.9 and 125.3 g for group A, B, C E and F,respectively. Mean percent mortality was 7.5, 5.0, 5.0, 5.0, 0.0 and 7.5 for group A,B, C, D, E and F respectively. Mortality was lower in group E (0.0 %) as comparedto other groups. It was concluded that B. lycium added to feed at the rate of 2.0%can be used broiler production for optimum performance from economic point ofview. It is further suggested that research trials may conducted to investigatethe effect of B. lycium on the immune system of the birds.
