Background: Nutritional strategies targeting improvement of poultry performance and disease prevention are currently being developed and in this respect the dietary intake of spiced essential oils and pre-biotics in raising broilers is receiving attention. OBJECTIVES: This study was conducted to compare the effects of diet containing ginger essential oils (GEO) and mannan-oligosaccharide (MOS) ...

In this study, we examined the effects of formic acid administration to the drinking water on performance, intestinal microflora and carcass contamination in male broilers. A total of 312 day-old male broiler chicks were allocated to two groups with three replicates. The first group (control) received normal drinking water (pH 7.4) during the experiment. The second group consumed acidified drin...

In the present study day-old specific-pathogen-free (SPF) and commercial broilers with maternally derived fowl adenovirus serotype 1 (FAdV-1) antibodies were orally infected with a European "pathogenic" FAdV-1, isolated from broilers showing signs of gizzard erosion. During the experiment, broilers were observed and weighed daily up to 17 days post infection (dpi). Clinically, both infected gro...

The present study investigated the dietary impact of dried olive pulp (OP) on growth performance, gut health and some welfare behavior characteristics broilers. It was conducted in a commercial poultry farm using 108 13 day-old Ross male Chickens were equally randomly assigned to 3 treatments, CON, OP3 OP6, based incorporation rate OP ration (0%, 3%, 6%, respectively). A beneficial foot pad der...

Background: The application of phytogenic additives in the form of essential oils have attracted considerable attention in poultry industry. OBJECTIVES: An experiment was conducted to evaluate effects of the blends of essential oils (EO) isolated from some medicinal plants including savory, thyme, fennel and rosemary on performance, blood metabolites, intestinal microflora, and meat quality of...

Objective: An experiment was conducted to investigate the effects of citrus brown snail powder as a source of calcium on growth performance, tibia characteristics, immune response and blood metabolites in broiler chickens.  Methods: One hundred and eighty 1-day old chicks were randomly distributed into four treatments, each of which had three replicates. Each replicate contains 15 chicks. The t...

In order to use the “Trinidad de Guedes" phosphorite (TGP) as a supplement of calcium and phosphorus in animals, its concentrations of heavy metals were determined and their deposition was analyzed in broilers. Toxic elements were determined using atomic absorption spectrophotometry. The mean levels of heavy metals found in TGP were 82.5 mg/kg lead (Pb), 7.2 mg/kg cadmium (Cd), 1056.9 mg/kg man...

Consumption of contaminated poultry meat is still an important cause of Salmonella infections in humans and there is a need for control methods that protect broilers from day-of-hatch until slaughter age against infection with Salmonella. Colonisation-inhibition, a concept in which a live Salmonella strain is orally administered to day-old chickens and protects against subsequent challenge, can...

in this study, 480 on-day-old arbor acres broiler chicks were used in a 2*3 factorial arrangment with 2 levels of hull-less barley (0.30%)and 3 levels of enzyme (0.300 and 600g/ton), to investigate the effect of diets containing high soluble non-starch polysaccharides (nsps) concentrations on morphological characteristics of small intestine and performance of broilers. increasing in concentrati...

Campylobacter jejuni is one of the most common causes of acute enteritis worldwide. Chickens are believed to be the main reservoir of C. jejuni. The role that host genetics play in resistance/susceptibility to C. jejuni colonization in broilers is still not clear. Day-old broilers from 2 parental lines (A and B) and their F(1) reciprocal crosses (C and D) were challenged orally with 10(5) cfu o...
