Alleviating the effects of transportation stress was the purpose of this study by using 270 thirty-fiveday-old Ross 308 broiler chickens to check out the effects of vitamin C and acetyl salicylic acid (ASA) at different levels via drinking water. Birds in the experiment were randomly allocated to 27 identical pens (041×120×90 cm) with 10 birds each (5 males and 5 females -almost equal in weight-). At the last 24 hours of experiment pens were assigned to 9 water treatments: at levels of 0 (Control),50mg/L vitamin (T1),100mg/L vitamin C (T2), 1 gm/L salicylic acid (T3), 1.5 gm/L salicylic acid (T4), 50mg/L vitamin C with 1 gm/L salicylic acid (T5), 50mg/L vitamin C with 1.5 gm/L salicylic acid (T6), 100mg/L vitamin C with 1 gm/L salicylic acid (T7) and 100mg/L vitamin C with 1.5 gm/L salicylic acid (T8). Studied traits were: glucose, total protein, uric acid, albumin, calcium, globulin, ALT, AST, Creatine Kinase and hormones (T3 and T4) studied in this experiment. Results indicate that incorporating Vit. C and ASA into broilers water compared to control group decrease the value of all stress indicator in a way that each of (glucose, albumin, globulin, uric acid, calcium, ALT, AST, Creatine Kinase and T3) significantly decreased. However, T4 was significantly increased while total protein was not changed. Results concluded that supplementation of the broiler drinking water with Vitamin C and ASA before transportation can be used as effective way for alleviating transporting stress and supporting the broilers to have more stable physiology during transportation.
The present study aims to assess different levels of parsley on the performance of broilers. The number of commercial broiler chicks (Ross 308) was 120 day old, randomly divided into 5 treatments with 3 replicates, meaning that each treatment had 24 chicks over a 6 week period. T1 was a control group whose diet level was lack of supplements (core diet). However, other T2, T3, T4 and T5 treatments included supplementing parsley at the level of 3, 6, 9 and 12 g/kg respectively. As part of the growth performance parameter at the end of the experiment, 4 chickens were slaughtered to estimate carcass and muscle characteristics. Therefore, the use of parsley at the rate of 9 g/kg had a significant influence on body weight and body weight gain. Efficiency of feed conversion and feed intake improved numerically compared to the control group throughout the study period. The highest thigh and carcass weights were obtained at a parsley feed level of 9 g/kg and there was no difference between treatments for animal weight, percent dressing. and the wing. In addition, there was no significant difference (P<0.05) in organ weights between the different treatments.
