Abstract

The aim of current study was to evaluate the effect of Stiking Assa (Ferula Assa Foetida) powder on performance and some immunity parameters of broiler chicks. A total of 200 one-day-old broiler chicks were randomly assigned in 5 experimental groups: 0, 0.25, 0.50, 0.75 and 1 percent Stiking Assa. Each treatment was assigned to four replicates of 10 birds according to a completely randomized design. At 1-21 days of age, birds fed diet containing 0.25 and 1 percent Ferula Assa Foetida (FA F) had lower growth rate compared with the control (p<0.5). At 22-42 days of age, the highest body weight gain (BWG) was observed in 0.75% FAT diet. At whole of experiment (1-42 days of age), adding FAT to diet did not improved (BWG). Adding FAT to diet at 1-21 and 22-42 days of age had not significant effect on feed intake (p>0.5). At 1-21 days of age, adding FAT to the diet did not significantly effect FCR (p>0.5) but at 22-42 days of age the lowest FCR was observed in birds fed 0.75% FAT compared with the control (p<0.5). Relative Carcase traits, heart and liver did not effected by dietary treatments (p>0.5). Birds fed diet containing 0. 5 and 0.75% FA F had higher relative intestine weight compared with control (p<0.5). Relative gizzard weight was lower in 0.5 and 0.75% treatment compared with control (p<0.5). Effect of dietary treatment on relative Proventriculus, weight, jujenum and ileum was not significant (p>0.5) but deudenum length significantly increased by dietary FAF compared with control (p<0.5). Blood parameters did not significantly affected by adding FAF to the diet (p>0.5). Early and secondary antibody titre against SRBC was higher in 0.75% FAF compared with control (p<0.5) and birds fed FAF had higher secondary antibody titre against SRBC as well as antibody titre against NDV, IB and cellular immunity (p<0.5). Ileal dietary FAF did not affect relative spleen and bursa weights (p>0.5). Lactica acid bacteria population improved by using FAF in diet (p<0.5). Result of this experiment has shown that using 0.75% FAF in diet of broilers could improve FCR, Humoral and cellular immune responses as well as Ileal lactic acid bacteria population.
