Effect of ethanol consumption on fear response in human and conventional animal models (rodents) is controversial. The present study aimed to investigate the effect of ethanol administration on fearfulness in poultry as an alternative animal model.Being a reliable measure in avian species, tonic immobility was used to evaluate the fear response in 60 roosters orally administered with ethanol. D...

There is accumulating evidence that birds of prey are susceptible to fatal infection with highly pathogenic avian influenza (HPAI) virus. We studied the antigenic, molecular, phylogenetic, and pathogenic properties of 2 HPAI H5N1 viruses isolated from dead falcons in Saudi Arabia and Kuwait in 2005 and 2007, respectively. Phylogenetic and antigenic analyses grouped both isolates in clade 2.2 (Q...

The effects of dietary supplemental guanidinoacetic acid (GAA) on performance, biochemical indices and meat pH of broilers with cold-induced ascites were studied. A total of 640 day-old male broiler chicks (Cobb 500) were assigned to four dietary treatments including control diet; control diet supplemented with either 0.6, 1.2 or 1.8 g of GAA per kg of feed. Each treatment was replicated in 8 b...

The objective of this study was to investigate the effects of feeding electron irradiated flaxseed (FS) on performance, carcass characteristics, blood parameters, digesta viscosity, and nutrient digestibility in broiler chickens. In a 2 × 2 factorial arrangement, 320 day-old broiler chicks were randomly assigned to one of five experimental diets, each with four replicates containing 16 chicks e...

Objective: The experiment was conducted to evaluate the effect of different levels of germinated barley on performance and egg quality in laying hen. Methods: One hundred and twenty laying hens, 44-weeks old, Lohmann LSL hens were used in this experiment. Birds were assigned randomly to the groups, each of which consisted of 20 birds (4 replicate cages each containing 5 birds). The experiment w...

the purpose of this study was to evaluate the effect of zilpaterol hydrochloride on the growth performance, carcass quality and blood parameters with128 male quails at 26 days of age were divided into four treatments which each treatment consists of four replicates of 8 birds. the birds received daily 0, 0.2, 0.225, or 0.25 mg/kg of live weight d−1zilpaterol. after three days of withdrawing zil...

effect of probiotic (clostat) levels on the performance and immune response of heat stressed broilers, was evaluated in a completely randomized design on 144 day-old male ross broiler chicks with four treatments and four replicates (nine birds each). experimental diets were consisted in four levels of probiotic (0, 0.05, 0.1 and 0.2). birds were raised under normal condition till 25 days of age...

P L p s fi v p v bstract. In this article, we present a fast switching filter for impulive noise removal from color images. The filter exploits the hue, aturation, and lightness color space and is based on the peer roup concept, which allows for the fast detection of noise in a eighborhood without resorting to pairwise distance computations etween each pixel. Experiments on large set of diverse...

avian intestinal spirochaetosis (ais) is a condition arising from colonization of the caeca and colon of birds with anaerobic spirochaetes of the genus brchyspira. the purpose of the present study was to evaluate pcr amplification from formalin-fixed, paraffin-embedded tissue method for detecting infected laying hens with brachyspira pilosicoli  with the same primers that have been used for det...
