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 b...

Abstract The study aimed to assess the effect of dietary inulin (1% inclusion) supplements on broiler chickens’ meat antioxidant compounds. experiment was carried out under heat-stress conditions, 60 Ross 308 chickens. took place in an experimental hall with digestibility pens and controlled humidity, ventilation light regime. Each treatment (2 groups, C E) replicated 6 times 5 chicks per repli...

A dose-response experiment with seven supplemental pyridoxine levels (0, 0.66, 1.32, 1.98, 2.64, 3.30, and 3.96 mg/kg) was conducted to investigate the effects of pyridoxine on growth performance and plasma aminotransferases and homocysteine of White Pekin ducks and to estimate pyridoxine requirement for these birds. A total of 336 one-day-old male White Pekin ducks were divided to 7 experiment...

A dose-response experiment with 6 dietary energy levels (2,600, 2,700, 2,800, 2,900, 3,000, 3,100 kcal of AME /kg) was conducted to study the effects of dietary energy on growth performance and carcass quality of White Pekin ducks from 2 to 6 wk of age. Six hundred 14-d-old White Pekin ducks were randomly divided to 6 dietary treatments, each containing 5 replicate pens with 10 males and 10 fem...

background: use of synbiotic and zinc sources had synergetic effects on broiler chickens performance and immune response improvements. objectives: this experiment was carried out to evaluate the effect of synbiotic and zinc sources on broiler chickens performance, immune response and gut morphology. methods: a total of 780, one-day old male broiler chicks were randomly assigned in factorial met...

a study was carried out to evaluate the effects of r. coriaria l. and p. farcta extracts as alternatives to antibiotic growth promoters in broilers diet. a total of 300 one-day-old male ross 308 chicks were randomly allocated to four dietary treatments (five pen replicates, 15 birds per pen) for the 0- to 28-d period, and all data were analyzed in a randomized complete design. dietary treatment...

background: glutamine supplementation to the pre-starter diet of broiler chicks could improve their performance during the first week of post-hatch. objectives: this experiment was conducted to evaluate the influence of glutamine levels in the pre-starter diet on intestinal mucosa morphology and performance of broiler chicks. method: a total of 160 ross 308, one-day old broilers were used in a ...

A study was conducted to determine if prior exposure with bacteriophage would limit the ability of the same bacteriophage to treat colibacillosis. There were 5 treatments with 3 replicate pens of 20 birds per pen. The treatments consisted of 1) control, 2) birds treated with bacteriophage at 10 and 17 d of age, 3) birds challenged with Escherichia coli at 17 d of age, 4) birds challenged with E...

We examined the effect of dietary Turkish propolis and flavomycin on growth performance, carcass characteristics, internal organ weights and some serum variables in quail (Coturnix coturnix japonica) birds. One hundred and fifty day-old quails were randomly divided into five groups, with ten replicate pens per treatment and three birds per pen. One group received the basal diet (antibiotic-free...

Two experiments were conducted to study the effects of stocking density on growth performance, carcass yield, and foot pad lesions of White Pekin ducks from hatch to 14 d of age (experiment 1) and from 14 to 42 d of age (experiment 2), respectively. All ducks were reared in raised plastic wire-floor pens with a pen size of 30 m(2), and males and females were mixed at a ratio of 1:1 in each pen ...
