This experiment was conducted to study the effect of dietary propionic acid on inhibitory effect of Salmonella gallinarum. Day-old 144 broiler chicks were randomly distributed into four dietary treatments, three replicates per treatment. The four dietary treatments consisted of 0.0, 0.6, 1.2, and 1.8% dietary propionic acid. Chicks were challenged orally on three days of age with 10 cfu Salmone...

An experiment was conducted using a total of 336 one-day-old, Arbor Acres commercial male broilers to investigate the effect of dietary Mn supplementation on carcass traits, meat quality, lipid oxidation, relative enzyme activities in abdominal fat and meat, and Mn-containing superoxide dismutase (MnSOD) mRNA level in meat. Broilers were randomly allotted by BW to 1 of 8 replicate cages (6 chic...

A total of 450 one-day-old Arbor Acres male chickens were used to investigate the effects of zinc oxide-montmorillonite hybrid (ZnO-MMT) on growth performance, intestinal structure, and function. The birds were allotted to 5 dietary treatments for 21 d, each of which was replicated 6 times with 15 chicks per replicate. The dietary treatments were 1) corn-soybean meal diet (basal, containing 42....

Twelve (12) weeks feeding trial was conducted to determine the effect of fatty acid content/total lipid and carcass characteristics/organoleptic qualities of broiler fed diets supplemented with dietary fat sources at levels of 5% saturated and 5% unsaturated. Three experimental diets identified as T1, T2 and T3 were formulated, the control diet T1 was with 0% fat, T2 contained palm oil at 5% in...

Two experiments were conducted to evaluate the effect of supplemental Gln on growth performance, development of the gastrointestinal tract, and humoral immune response of broilers. Immediately after hatch 6 replicate pens of 6 chicks were randomly assigned to 1 of 7 (experiment 1) or 5 (experiment 2) dietary treatments for 21 d. On d 4, 7, 14, and 21, twelve chicks per treatment (2 chicks/pen) ...

introduction : antibiotic feed additives have long been used as growth promoters (10). however, consumers and health authorities increasingly dictate that the use of synthetic food additives should be phased out and, where possible, only natural products should be used. hence, alternatives from natural sources with potential antioxidant activity are investigated (16). olive leaves are a good so...

This experiment aimed to evaluate the effects of probiotic administration route (PAR),dietary nutrient density (DND) and Eimeria challenge (ECH) on performance, gut morphology, and hematological variables in broiler chickens. Eggs carrying 17.5-day-old broiler embryos were injected with 0.1 mL distilled water (vehicle control) or 0.1 mL distilled water containing probiotic. A group of ...

This study evaluates low protein diets with amino acid supplement on growth, biochemical markers and muscle acids profile in broilers under high ambient temperature. A total of 480 one-day-old chicks were allocated into three treatments four replicates (n = 40). Control fed optimal which contains 23% 21% crude (CP) 65% methionine + cysteine/ lysine (Met Cys/Lys) 55% threonine/lysine (Thr/Lys), ...

two experiments were conducted to determine the effect of phytase supplementation on layer hens and broiler chickens performance and compare the use of phytase nutrient equivalency values in feed formulation with those fed conventional diet. in the first ex-periment, 640 commercial broiler chicks were used from 11 to 49 days of age. the ex-perimental units were allocated at random to 4 dietary ...
