Single cell protein (SCP) is the definition for dried cells originated from single-celled organisms intended to be used as a protein source in human foods or animal feeds. An experiment has been conducted to evaluate the various levels of single cell protein on fecal microflora and productive traits of broiler chickens. A total of 192 day-old Ross 308 male chicks were randomly divided into 4 tr...

in order to investigate the effects of artichoke leaf powder and vitamin eon performance, internal organs relative weight and some blood parameters, 240 day-old quails were assigned to four treatments including, basal diet (control), basal diet supplemented with levels of 1.5 and 3 percent of artichoke leaf powder and basal diet supplemented with 300 mg/kg diet vitamin e with four replicates an...

Production performance and egg quality characteristics of pullets and spent layers were compared in this study. Forty birds, each from the flocks of pullets (24 weeks old) and spent layers (76 weeks old) were selected as experimental birds. The birds from each age group were divided into five replicates, each comprising of eight birds. All the experimental birds were fed a commercial layer rati...

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...

To asses the effect of turmeric (Curcuma longa) supplementation on antioxidants and immunity of broiler chickens, seventy five run day old coloured synthetic broiler chicks were randomly divided into 3 groups (25 chicks per each) of mixed sex. Group I served as control (without any supplementation), whereas birds in groups II and III were supplemented with 0.5% and 1.0% Curcuma longa powder res...

Four experiments were carried out to determine the AMEn of ground flaxseed in chickens of different ages and to study the effect of feeding flaxseed in pelleted or crumbled diets on flaxseed AMEn. A corn-soybean meal basal diet was prepared, in which the energy-yielding ingredients were substituted with ground flaxseed at 5, 10, 15, or 20%. Experiments 1, 2, and 3 consisted of these five dietar...

We tested the hypothesis that experience of migration from Europe to tropical Africa by Garden Warblers is associated with changes in the relative volume of the hippocampus, a brain region thought to be involved in processing spatial information, including that used in navigation. Relative hippocampal volume was larger in birds at least one year old that had migrated to and from Africa, than in...

probiotics are beneficial microorganisms which will be considered as alternatives to antibiotic growth promoters.the aim of the present study was to investigate the effect of probiotic administration in hatchery on performance, blood parameters and immune response of broilers. three hundereds 1-d-old male chicks (ross 308) were assigned to five experimental groups of three replications. birds o...

This research was conducted to investigate the effect of inclusion of wheat bran (as a source of insoluble fiber) in a barley-based diet, fed from 11 to 42 d of age, on villus morphology of jejunum, serum cholesterol level, abdominal fat pad and growth performance of broiler chickens. Three hundred and thirty six 10-d-old female Ross 308 chicks were allocated to six diets with four replicates o...

In this study we compared protection by DNA vaccination with the F (pCMV-F) or N (pCMV-N) gene from avian metapneumovirus (aMPV) in turkeys. One-week-old turkey poults received two intramuscular injections 2 wk apart. Birds were challenged with a turkey-embryo-adapted aMPV at 5 wk of age. Birds vaccinated with pCMV-F had decreased clinical signs of disease as well as significantly reduced virus...
