The role of the autonomic nerve on the gastric motility of the domestic fowl has been investigated by Nolf (1), Ihnen (2) and Hassan (3). Nolf has reported that both excitatory and inhibitory fibres are included in the vagus and also in the sympathetic nerve to the proventriculus and gizzard. However, there is little detailed study on the mechanism which causes excitatory and inhibitory respons...

Thick myosin filaments, in addition to actin filaments, were found in sections of glycerinated chicken gizzard smooth muscle when fixed at a pH below 6.6. The thick filaments were often grouped into bundles and run in the longitudinal axis of the smooth muscle cell. Each thick filament was surrounded by a number of thin filaments, giving the filament arrangement a rosette appearance in cross-se...

The Black Brant Branta bernicla nigricans is a seagrass-obligate goose, strongly tied to the estuaries of the Pacific Flyway coast of North America. Black Brant are unique in that they remain reliant on their traditional food resource, in contrast to other Brent Goose populations that now readily switch to feed on agricultural land during migration and in winter. While Black Brant use of coasta...

The aim of study was to compare carcass characteristics of broiler housed under two different rearing systems (cage and floor) in three housing zones. For this purpose, 240 day old commercial broilers (Hubbard Classic) were purchased and half of them were reared in cages and other half on floor. Under each system, the birds were further divided in three zones of house (near vent, middle and nea...

The conducted research was done in Grda rasha field (Salahaddin University) for one month to compare the impacts of Alcea kurdica powder, Rifaxmine, and Ranitidine as anti-lesion immune-strengthening agents on stress-induced quails which are affecting their growth rate severe cases causing gizzard erosion deep intestinal lesions. To do that, 75 (12 weeks old) were grouped into six treatments wi...

The influence of including 20% whole corn, differing in grain hardness, on the performance, nutrient utilization and gut characteristics of broiler starters was investigated. The experimental design was a 3 × 2 factorial arrangement of treatments evaluating corn hardness (hard, semi hard or soft) with diets based on ground corn or 20% of ground corn replaced by whole corn. The 3 corn cultivars ...

Total sixty four straight run broiler chicks of two daysold were fed a control diet and diet supplemented with Fungi inhibitor (FI): Gentian violet (GV), Copper sulphate (CS), GV+CSto evaluate the effect of dietary FI on the performance characteristics of broiler. The levels of GV, CS and GV+CS were 0.05%, 0.06% and 0.025%+0.06%, respectively. Dietary FI did not alter the growth rate, feed inta...
