Sera of 30 Belgian and 10 Northern French chicken farms were tested by a Chlamydia (C.) psittaci major outer membrane protein (MOMP) based ELISA. Ninety-six percent, 93% and 90% of the Belgian broilers, broiler breeders and layers were seropositive. Ninety-one percent of the French broilers were seropositive. In addition, tissues of 5 Belgian and 5 French broiler farms were examined at slaughte...

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...
