چکیده
|
The objective of this research was to investigate the efficacy of dietary inclusion of probiotics primalac® and bactocell® and prebiotic fermacto® on broiler’s performance and immune response, individually or in combination. a total of 540 one-d-old male ross 308 broiler chicks were allocated into 6 experimental treatments with 6 replicates of 15 birds per replicate from 1 to 42 d of age. the birds received a basal diet (control) or the basal diet supplemented with probiotic primalac® (pp), probiotic bactocell® (pb), prebiotic fermacto® (pre), probiotic bactocell® + prebiotic fermacto® (pbpre) or probiotic primalac® + prebiotic fermacto® (pppre). performance parameters were measured from 1-42 d of age. a suspension of sheep red blood cells (srbcs) was injected into the breast of 3 birds from each replicate on d 22, and the antibody titer was measured on d 30. at d 22, blood samples (from 3 birds per replicate) were taken for measuring the white blood cells (wbcs), heterophil (he) percent, lymphocyte (ly) percent, and the ratio of heterophil:lymphocyte (h/l). no significant differences were found between the control and supplemented groups in average daily gain (adg), average daily feed intake (adfi), antibody titer against srbcs, he percent, ly percent and h/l. addition of pbpre or pppre to the diet improved fcr by 8.5 and 12.7%, respectively, compared with the control group, and pbpre supplementation resulted in an increase in wbcs compared to other treatment groups.
