Increased dietary protein intake rapidly (3 h) decreases malic enzyme and increases hepatic histidase mRNA expression. Experiments were conducted to determine the role that individual dispensable amino acids and nonprotein N sources might have in regulating the activity of these enzymes and to determine if the addition of a N supplement to a practical broiler diet during the entire rearing peri...

The purpose of this research work was to evaluate the seed extract (aqueous) on the visceral organs of broiler chicks. One hundred and sixty, day old broiler chicks were randomly assigned to four treatments A, B, C and D. Each treatment was replicated four times with ten chicks per replicate. Group A, B, C received the aqueous extract of Fenugreek @ 10, 20 and 30 ml/L, respectively while group ...

The synergistic effects of two contaminating mycotoxins aflatoxin (AF) and T-2 toxin (T-2) in the feed of poultry on the performance of broiler chickens were studied individually and in combination, by using one hundred and sixty eight day-old commercial broiler chicks obtained from a commercial hatchery and randomly separated into four groups in 2X2 Complete Randomized Design of three replicat...

background & aim: the fruit of citrullus colocynthis has a bitter taste and antibacterial properties against pathogen factors.the aim of current research was to study the effects of different dietary level of bitter cucumber fruit powderwith and without protexin probiotic supplementation on growth performance, carcass traits and intestinal morphology of broiler chicks. experimental: two hundred...

The aim of the experiment was to evaluate effects of zinc gluconate (ZnGlu) and probiotic administration on the daily rhythm of cloacal temperature (tcloacal) in broiler chickens of different age groups during the hot-dry season. One-day-old broiler chicks (n = 60) were divided into groups I-IV of 15 chicks per group, and treated for 35 days: Group I (control) was given deionized water; Group I...

Beak trimming is necessary in commercial broiler breeders to prevent or decrease trauma as they mature. Two common beak-trimming methods were evaluated by early performance comparison with nontrimmed chicks (NBT). The robotic electrocautery device (ECD) trims and cauterizes the beak tip. The robotic infrared beak-trimming device (IBT) applies an infrared light beam to destroy the live basal tis...

BACKGROUND A bacterial role in the obesity pandemic has been suspected based on the ingestion of probiotics that can modify the gut flora. The objective of our study was to determine if increased Lactobacillus sp. in the gut flora of newborn broiler chicks and ducks could result in weight gain increase. METHODOLOGY Female broiler chicks (Gallus gallus domesticus) and ducks (Anas platyrhynchos...
