Polyphenol-rich natural sugarcane extract can protect living cells against oxidative damage that could negatively affect broiler performance. The objective was to evaluate the effect of graded levels a dietary on growth performance chickens under local conditions. A study conducted by housing total 960 broilers (Cobb 500) in litter floor pens and feeding (0, 0.1, 0.2 0.3%) from 0 35 days. Each ...

an investigation was carried out to evaluate the growth performance of six commercial broiler hybridsavailable in iran (arbor acres, arian, cobb 500, hubbard, lohmann and ross 508). two hundred and fiftyfertile eggs of each hybrid were taken from different breeder farms, all over the country. the similarity offlocks ages and their health conditions were considered. after hatching, the sexed chi...

the present study was carried out to examine the effects of satureja khuzistanica essential oils(skeo), on cholesterol content, fatty acids composition, and thiobarbituric acid reactive substances,(tbars) concentration of raw breast meat in broiler chickens. a total of 720 one-day-old broilerchicks (cobb 500) were taken as sample to study the effects of six experimental treatments in 6replicate...

Results The overall failure rate was 31% after bracing and 52% after observation. Age, gender, Risser, Sanders’ digital maturity stage (DMS), curve type and Cobb angle were all associated with outcome. DMS stages were more predictive of failure than Risser grade, even with age in the model. The best-fitting model included the DMS (1-2, 3, or 4+), Cobb angle, and treatment (p<0.0001, c statistic...

The present study was conducted to investigate the effect of dietary supplementation of turmeric (TEO) and rosemary (REO) essential oils on growth performance and oxidative stability of broiler meat. Five hundred forty day-old chickens (Cobb 500) were randomly allotted to a 3 × 3 factorial arrangement with three levels of turmeric essential oil (T1=0, T2=75 and T3=150 mg/kg) and three levels of...

The objective of this study was to assess the hatch window, hatchability and quality broilers` chick obtained from different breeder strains in a commercial hatchery. A total 57 600 hatching eggs (28 800 per strain) were collected flocks Cobb 500 Ross 308 broiler parent stocks at 60-61 weeks age. Each strain randomly coded as B strain. mean value eggshell temperature found be higher Strain (101...

BACKGROUND Supine imaging modalities provide valuable 3D information on scoliotic anatomy, but the altered spine geometry between the supine and standing positions affects the Cobb angle measurement. Previous studies report a mean 7°-10° Cobb angle increase from supine to standing, but none have reported the effect of endplate pre-selection or whether other parameters affect this Cobb angle dif...
