In this study, Lactobacillus plantarum (ATCC 8014), Lactobacillus casei (ATCC 393), Lactobacillus lactis (ATCC 7830) and Lactobacillus fermentum (ATCC 9338) and L. reuteri strains were isolated from goat, sheep, cattle and camel rumen. The bacterial strains were cultured anaerobically in MRS broth and MRS agar at 37±1°C and administered (10 CFU/mL) separately to 1 day-old Lohman, Hubbard and Ro...

The objective of this study was to evaluate the effect of a dry air-chilling (AC) method on sensory texture and flavor descriptive profiles of broiler pectoralis major (fillet) and pectoralis minor (tender). The profiles of the muscles immersion-chilled and deboned at the same postmortem time and the profiles of the muscles hot-boned (or no chill) were used for the comparison. A total of 108 ev...

Broiler breast fillets are sometimes characterized grossly by white parallel striations in the direction of the muscle fibers, and the condition is referred to as white striping. Depending on the severity of white striping, fillets can be classified as normal (NORM), moderate (MOD), or severe (SEV). The present study was intended to determine the factors associated with the occurrence of white ...

Genetic selection for improved meat yields, digestive efficiency and growth rates have transformed the biology of broiler chickens. Modern birds undergo a 50-fold multiplication in body mass in just six weeks, from hatching to slaughter weight. However, this selection for rapid growth and improvements in broiler productivity is also widely thought to be associated with increased welfare problem...

An experiment was conducted to compare the effect of selenium sources on performance, Se incorporation into certain poultry tissues (blood, liver and breast muscle) and eggs, hatchability, glutathione peroxidase activities in tissues and eggs in broiler breeder. Broiler breeder hens were allocated to six diet treatments factorially arranged with three selenium sources (Sodium selenite, Selenium...

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...

The competency of garlic and pennywort to improve broiler chicken growth and influence intestinal microbial communities and fatty acid composition of breast meat were studied. Two hundred forty, "day-old" chicks were randomly allocated to 4 treatment groups consisting of 6 replications of 10 chicks in each pen. The groups were assigned to receive treatment diets as follows: i) basal diet (contr...

The aim of this study was to evaluate the effect of the baical skullcap root (Scutellaria baicalensis radix) on the performance, chemical composition of the muscles and sensory characteristics of the meat of broiler chickens. 120 one-day old Hubbard Hi-Y broiler hybrids were assigned to four groups of 30 each and fed either a basal diet (control) or a basal diet supplemented with 0.5%, 1.0% or ...
