The presence of glucokinase (GK), a critical enzyme controlling glucose homeostasis and particularly liver glucose utilisation in mammals, has long been a matter of debate in avian species as a number of investigators failed to detect glucokinase activity in livers from the chicken and several other avian species. In this study we cloned a partial GK cDNA from mule duck livers and we measured G...

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 ...

This study was performed with growing chicken (1 to 56 d of age) to evaluate the effects of malic acid on broiler chicken performance. Malic acid was added to the water and offered to chicken freely from first to end of experiment with constant concentration. The treatments were zero (as a control), 0.05, 0.10, and 0.15 percent of malic acid which dissolved in water and given to them in waterer...

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...

the main purpose of this study was to investigate the effects of euphorbia hirta and acidifiers supplement on resistance of broiler chickens against salmonella enteritidis infection. a total of 120 day-old male broiler chicks were randomly assigned to 3 dietary treatments. 1) basal diet, 2) basal diet supplemented with 2 g/kg organic acid (oa) and 3) basal diet supplemented with 7.5 g/kg e. hir...

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...
