a total of 288 broiler chickens (1 d old) were used in a 42-d growth trial to study the effects of chicory (cichorium intybus) and nettle (urtica dioica) with or without multi-enzyme on growth performance, carcass traits, and biochemical parameters. the corn-soybean based control diet and 8 experimental diets were fed to each of 3 pens of chickens (12 chickens/pen). treatments were as follows: ...

this experiment was conducted to investigate the effects of different levels of oxidized fat (yellow grease) and copper sulfate on performance, carcass traits, blood metabolites and immune cells of broilers. this study was carried out as a 3 × 2 factorial experiment with 3 levels of oxidized fat (0, 2 and 4%) and 2 levels of copper sulfate (0 and 300 mg/kg) in 6 treatments, 3 replicates and 12 ...

Multidrug-resistant Escherichia coli infections are a growing public health concern. This study analyzed the possibility of contamination of commercial poultry meat (broiler and free-range) with pathogenic and or multi-resistant E. coli in retail chain poultry meat markets in India. We analyzed 168 E. coli isolates from broiler and free-range retail poultry (meat/ceca) sampled over a wide geogr...

this study was conducted to determine the effect of oak acorn (quercus castaneifolia) on performance, small intestine morphology, ileal digestibility of nutrient, carcass and some blood parameters in broiler chicks. a total of fifty hundred four one-d old male chickens (ross308 strain) with seven treatments and four replicates in each treatment were used. experimental diets were: control (corn-...

Due to concern about increasing mortality among 7 -day old chicks in a chicken hatchery the management arranged to screen all hatchery staff for salmonella excretion. The hatchery is part of a complex involving all stages of chicken meat production but is physically separate from the broiler units and chicken processing plant. The hatchery also has its own staff, there being no exchange of staf...

Ornithobacteriosis is an infectious disease of avian species that has been reported in almost all countries around the world, except Thailand. The objectives of this study were to determine the seroprevalence of Ornithobacterium rhinotracheale (ORT) and to isolate and identify ORT in broilers and broiler breeders in Thailand. Chicken antibodies had been randomly checked from 17 farms (19 flocks...

an experiment was conducted to evaluate the effect of different levels of germinated barley (gb) on live performance and carcass traits in broiler chickens. the experiment lasted for 5 weeks starting from 7 days of age and ending at 42 days of age. chicks (ross 308) were fed six dietary treatments including a corn–soy diet (corn diet), a barley–soy diet (barley diet), a barley diet plus enzymes...

the aim of this study was to isolate escherichia coli from chickens and to determine the presence of the eaea gene, a virulence factor detected in escherichia coli, in the isolates by polymerase chain reaction (pcr). different chicken organs (lung, liver and spleen) were inoculated onto blood agar and biochemical tests were performed on the suspicious isolates. escherichiacoliwas isolated from ...

the experiment was conducted on forty five broiler chickens at 4 weeks of age, for a period of threeweeks, to assess the effect of complete replacement of fish meal with processed fish wastes (fish waste acidsilage and surimi waste powder) on the blood protein, lipid and antioxidant status in broiler chicken, eventhough an earlier study indicated that this replacement induced normal growth rate...
