Between October 15, 2021, and November 26, this study was carried out in the broiler field at College of Agricultural Engineering Sciences, University Baghdad Abu Ghraib to examine effects adding various dosages onion powder, "Allium cepa linn", chicks' diets on physiological characteristics. The experiment employed 225 unsexed (Ross 308) one-day-old chicks with an average weight 40g. A total w...

Astaxanthin (ASX) is a xanthophyll pigment isolated from crustaceans and salmonids. Owing to its powerful antioxidant activity, ASX has been reported to have the potential to protect against gastric ulcers and a variety of other illnesses. Histamine (His) is a dietary factor that causes gastric erosion and ulceration in young chicks. In this study, we examined whether ASX had protective effects...

An outbreak of neurological disease occurred in pheasant chicks on a game farm in 2007. The disease was first seen in the 10th hatching of chicks on the farm. Affected chicks showed trembling and incoordination from the time of hatching, and subsequently blindness and cataract formation was seen in some of the affected chicks at 3 weeks of age. The peak mortality and culling figure was 21.0% in...

A total of 150 day old female chickens (Ross 308) were randomly allocated to 2 groups with 5 replicate and 15 chicks in each replicate to determine the effects of cold induced ascites on performance, antioxidant status, blood enzyme activities and bone metabolism. The two experimental treatments were: 1) chicks that reared under normal temperature (NT) and 2) chicks that reared under cold tempe...

This study was undertaken to investigate the growth performance and immune responses of broiler chicks fed diets supplemented with conjugated linoleic acid (CLA). Two hundred and forty day-old Arbor Acre male broiler chicks were randomly allotted into four dietary treatments with different inclusion levels of CLA (0, 2.5, 5.0 or 10.0 g pure CLA/kg) for 6 weeks. Growth performance, lysozyme acti...

The efficacy of metoclopramide for preventing organophosphate insecticide-induced (diazinon) toxicosis was evaluated in 7~14 days old chicks. Injection of metoclopramide at 25 mg/kg, s.c. 15 min before diazinon increased the oral 24 h median lethal dose of the insecticide in the chicks by 80%. Metoclopramide alone inhibited the in vitro and in vivo plasma and whole brain cholinesterase activiti...

To study the putative transfer of antibiotic resistance from broiler breeders to human, hen’s eggs and theirday-old chicks were examined for the presence of bacteria. The most frequently isolated organisms indecreasing order were: Streptococcus spp., Bacillus spp., Staphylococcus spp., Klebsiella spp., Enterobacterspp. and Escherichia coli followed by Citrobacter spp., Proteus spp. and Pseudomo...

The present work was carried out to evaluate and compare the productive and physiological performance and carcass traits of two local strains of chicks. Also, to find out the relationship among the studied traits. A total number of 450 one – day old chicks from each of Silver Montazah (S.M) and Matruoh (MAT), strains (210 males and 240 females) were randomly divided into four experimental group...

Absolute auditory thresholds were estimated in chickens at 0 and 4 days after hatching. Momentary suppressions of the chicks' regular peeping, following the onset of a tone, were used as indications of stimulus detection. In the first experiment a staircase procedure was used to estimate thresholds. The absolute thresholds of both ages were the same at low frequencies (250-500 Hz), but at highe...

this experiment was carried out at the college of agriculture university of salahaddin erbil. to study the effect of water supplementation with propolis on local quail performance, some physiological and immunological characteristics at 42 days old. a total of one thousand fifty (1050) hatched local quail eggs that obtained from the project of al-rashedia for agriculture researches center in mo...
