The present study was conducted to evaluate the effects of dietary threonine amino acid supplementation on growth performance and carcass characteristics of Japanese quails. Day old, two hundred and seventy quail chicks were divided into six dietary treatment groups comprising 45 birds each, which consisted of 3 subgroups containing 15 birds for each replicate. Experimental diets were prepared ...

low nutritive value and suitability of barley as a feedstuff for broilers is mainly due to its non-starch polysaccharides. an experiment was carried out to evaluate if diets high in barley alter the mechanisms responsible for the absorption of nutrients across the intestinal epithelium of broilers, using d-xylose absorption test. thirty, 14-d old male broiler chicks (ross 308) with similar body...

this experiment was conducted to investigate the effects of olive leaf (ol) on immune response and some blood metabolites of broiler chickens. a total of 400 one-day-old broiler chicks (male and female) were randomly assigned to 5 experimental treatments with 4 replicates of 20 birds each. birds of different treatments were given diets containing 0, 0.25, 0.5, 0.75 and 1% ol powder from 14 to 4...

We examined the adrenal response to handling stress of birds in different body conditions. In order to affect the birds' body condition, young (73-d old) female American kestrels (Falco sparverius) were maintained for 6 wk on one of three diets: a control diet (fed ad lib.) and two calorically restricted diets. To invoke a stress response, we removed birds from their cages and took repeated blo...

OBJECTIVE OBJECTIVE To evaluate diclofenac-induced biochemical and histopathological changes in White Leghorn birds. MATERIALS AND METHODS Six-week-old birds were equally divided into three groups of six birds each. Group I served as control and received vehicle orally. The birds of Group II and III were orally administered with a single low (2 mg/kg) and high dose (20 mg/kg) of diclofenac...

following experimental inoculation of 3-week-old turkeys with different titres (106, 104, 103, 102 and 101 egg infectious dose (eid50)) of a/ostrich/italy/984/2000 h7n1 highly pathogenic avian influenza virus (hpaiv), the selected tissues and organs were examined for pathological changes. tissue samples from different organs that obtained from dead and sacrificed birds were fixed in 10% neutral...

four hundred fifty day old unsexed broiler chicks were used in a 35-day trial at chittagong veterinary and animal sciences university farm to find out the effect of using crude soybean oil sediment (csos) as a substitute for refined soybean oil (rso) in broiler diet. the experiment was carried out following completely randomized design. the chicks were randomly distributed in three treatment gr...

Electrophysiological responses to pulsed linear acceleration stimuli were recorded in chicken embryos incubated for 19 or 20 days (E19/E20). Responses occurred within the first 16 ms following the stimulus onset. The evoked potentials disappeared following bilateral labyrinthectomy, but persisted following cochlear destruction alone, thus demonstrating that the responses were vestibular. Approx...
