to evaluate the effect of supplemental vitamin c (vc) levels on performance and immune response of broiler chicks, 300 day-old ross male broiler chicks were allocated to a completly randomized design of 5 treatments(500 and 1000 ppm in diet, 500 and 1000 ppm in drinking water and control). immunity was assessed as antibody production against infectious bronchitis virus (ibv) and newcastle disea...

The present study aimed to investigate the responses of broilers with different hatching weights (HW) to dietary methionine (Met). A total of 192 1-d-old Arbor Acres broiler chicks with different HW (heavy: 48·3 (sem 0·1) g and light: 41·7 (sem 0·1) g) were allocated to a 2 (HW) × 2 (Met) factorial arrangement with six replicates of eight chicks. Control starter (1-21 d) and finisher (22-42 d) ...

OBJECTIVE This study was conducted to investigate the effect of dietary onion (Allium cepa) extract (OE) supplementation on growth performance, apparent total tract retention (ATTR), blood profile, carcass characteristics and meat quality in broilers. METHODS Four hundred male broiler chicks (Ross 308, 3-d old) were randomly allocated to four dietary treatments for 28 d feeding trial. Each tr...

Abstract This study was conducted in the poultry field of Livestock Research Station Mosul Iraqi Ministry Agriculture during period 27/12/2021 to 8/2/2022 for purpose studying effect adding some plants oils and vitamin E on productive traits broiler chickens. where (480) one-day-old Roos-308 chicks were used, they distributed randomly by six experimental treatments each treatment 80 birds, incl...

this study was conducted to investigate the effect of ascites-related physiological and metabolic parameters in broiler chickens fed with different components of bentonite. two hundred and seven days old arian male chicks were allocated into five dietary treatment groups including 1) basal diet (control); 2) basal diet + 1% sulphated sodium bentonite (ssb); 3) basal diet + 1% non-processed sodi...

The present study was conducted to investigate the effect of xylo-oligosaccharide and xylanase supplementation on growth performance, carcass characteristics, nutrient digestibility, intestinal histology broilers. Six hundred day-old chicks (ROSS-308) were divided into four experimental groups (i.e. T1, T2, T3, T4). Each unit had six replicates 25 chicks/replicate. Following treatments offered:...

The effects of Trigonella foenum graecum (TF) and Foeniculum vulgare (FV) seeds powder on antimicro-bial activity and performance of broiler chickens were studied. Based on a completely randomized design, 240 broiler chicks (Ross 308) were assigned to 4 treatments and 4 replicates. The treatments were a basal diet (control, T 1), T 1 plus 0.5% TF (T 2), T 1 plus 0.5% FV (T 3) and TFFV (0.25% TF...

The present study aimed at investigating the effects of different dietary crude protein (CP) and threonine (Thr) levels on the performance, immune responses and jejunal morphology of broiler chicks. A total of 432 broiler chicks were randomly assigned to a 3×3 factorial arrangement of treatments including three different CP dietary levels (90, 95, and 100% of Ross 308 recommendations) and Thr (...

ABSTRACT- This study was designed to investigate the effects of adding different levels of date presscakes (DP), with and without enzyme supplementation (ES), on the ileal digestibility and growth performance of broiler. A completely randomized design containing 2 × 5 factorial arrangement of treatments (with and without enzyme supplementation and 5 levels of DP) was used. The enzyme complex co...

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...
