While characterizing the intestinal bacterial community of broiler chickens, we detected epsilon-proteobacterial DNA in the ilea of 3-day-old commercial broiler chicks (J. Lu, U. Idris, B. Harmon, C. Hofacre, J. J. Maurer, and M. D. Lee, Appl. Environ. Microbiol. 69:6816-6824, 2003). The sequences exhibited high levels of similarity to Campylobacter jejuni and Campylobacter coli sequences, sugg...

this experiment was carried out in order to study the effect of ionophore anticoccidial drugs (salinomycin, maduramycin and their combination) and the comparison of those effects on the performance, carcass characteristics and concentration of some minerals of serum in broiler chicks. this experiment was included four treatments: 1) basal diet, 2) basal diet with 60 mg/kg salinomycin, 3) basal ...

To determine if there is an ontogenetic change in stimulus coding, chickens between the day of hatching and 9-10 days old were tested using a habituation-generalization paradigm. Experiment 1 indicated that 1 day-old and 3--4-day-old chicks show similar habituation of an eye-opening response to auditory stimuli in the 800--1,200-Hz range. In Experiment 2 the eye-opening response to a 1,000-Hz s...

600 seven day-old ross broiler chicks were tested in a factorial experiment (2×5) with two levels of oil (three and six percent) and five levels of soybean oil and soapstock (100:0, 75:25, 50:50, 25:75 and 0:100) with four replicates. rations were isocaloric and isonitrogenus. the chicks of the rations with three percent fat had higher weight gain and lower feed intake and feed: gain ratio (p

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...

Palm kernel cake (PKC) is the main byproduct from the palm oil industry in several tropical countries that contains considerable amounts of oligosaccharide. We earlier demonstrated beneficial prebiotic effects of oligosaccharides extract of PKC (OligoPKC) in starter and finisher broiler birds. This study was envisaged to elucidate the effects of in ovo and/or oral administration of the OligoPKC...

Prostaglandin synthetic activity of neural retina and retinal pigment epithelium in chick retina was studied using arachidonic acid and prostaglandin H2 (intermediate prostaglandin endoperoxide) as substrates. To obtain sufficient enzyme activity in retinal pigment epithelium, cultured chick retinal pigment epithelial cells were used. Little arachidonic acid was converted into prostaglandins, a...

An experimental study in 180 day-old broiler chicks was conducted to evaluate efficacy of herbal liver tonic & growth promoter products on overall growth, performance and carcass quality parameters. Day old chicks were randomly divided into three groups, control group I was given no treatment while group II & III were administered herbal liver tonic & growth promoter products Superliv DS & Xliv...

The present study aimed to describe a simple technique for enema administration in one-day-old broiler chicks. For this purpose we used 455 unsexed health birds divided into four groups submitted to three different experimental protocols: in the first one, we measured the total length of the large intestine in order to establish a secure distance for probe introduction; in the second, we evalua...

This experiment was conducted to study the effect of dietary propionic acid on inhibitory effect of Salmonella gallinarum. Day-old 144 broiler chicks were randomly distributed into four dietary treatments, three replicates per treatment. The four dietary treatments consisted of 0.0, 0.6, 1.2, and 1.8% dietary propionic acid. Chicks were challenged orally on three days of age with 10 cfu Salmone...
