In order to investigate the effect of surplus jujube meal with or without Rovabio enzyme on growth performance, carcass traits and ileum morphology in broiler chicken; 320 male broiler chicks of Ross 308 were assigned to eight treatments, four replicates and 10 birds per each. The treatments included four levels of surplus jujube meal (0, 4, 7 and 10 percent) and two levels of Rovabio multi-enzyme (0 and 0.1 percent). The data were analyzed based on completely randomized design in factorial arrangement (2×4). The results showed that the birds fed diet containing 10% jujube with enzyme had a higher feed intake in the grower, finisher and whole periods as compared to control (no jujube and enzyme treatment; P<0.05). The main effect and interactions of enzymes and jujube had no effect on weight gain and feed conversion ratio. However, in the starter period when the birds fed diet contained 10% jujube along with enzyme, a higher weight gain than control was observed (P<0.05). Supplementation of 4% Jujube with enzyme increased the percentage of breast and the level of 7% jujube reduced abdominal fat compared to control (P<0.05). Compared to control, the birds fed diets containing 10% jujube with the enzyme had higher and lower villus height and width respectively (P<0.05). The ratio of villus height to crypt depth was the highest in birds fed enzyme (P<0.05). It is concluded that adding 10% of jujube to the diet of broiler chickens and supplementing it with enzyme could improve the performance and meat quality of broiler chicken.

The effects of seeds and whole plant powder and extract of Milk thistle (MT) plant in reducing the negative effects of feeding 500 ppb aflatoxin B1 (AFB1) on broiler chickens performance, carcass characteristics and some blood parameters were examined using 192 one-day old chick (Ross 308) in a completely randomized design with six treatments, four replicates and 8 birds per repetition. The experimental treatments included: 1) control, 2) contaminated control (CC), 3) CC + 0.5 percent of MT seed powder, 4) CC + 1 percent MT plant powder, 5) CC + 600mg/kg MT plant extract, 6) CC + 1000mg/kg MT plant extract. Results indicated that feeding contaminated diet reduced body weight gain and increased the feed conversion ratio and alanine aminotransferase enzyme compared with control in whole experimental period (P≤0.05). The inclusion of 1 percent MT plant powder to the contaminated diets improved weight gain and feed conversion ratio in 1-7, 7-21 days and whole experimental period (1-35 days) compared to the contaminated control (P≤0.05). The addition of 0.5 percent MT seed powder, 1 percent MT plant powder and 1000mg/kg MT plant extract to the contaminated diets decreased alanine aminotransferase enzyme (at 35d) compared to the contaminated control (P≤0.05). It was concluded that compared to other treatments, one percent MT plant powder was more effective in reducing the negative effects of feeding AFB1 in broiler chickens.
