Coccidiosis is a disease that limits the production and marketing of gallinaceous birds in North America, especially quails, pheasants and chukar partridges. Virtually no research has been conducted in South America on the causative agents of diseases among these birds, including coccidia. The aim of this work was to make first observations on Eimeria spp. in the chukar partridge Alectoris chuk...

The epidemiology of inclusion body hepatitis (IBH) was studied in poultry in northern India, from April 1990 to March 1994, to evaluate the various factors responsible for causing and determining the severity of the disease. Broiler chicks and Japanese quail (Coturnix coturnix japonica) were the species examined. The factor observed to be most commonly associated with IBH was the presence of af...

The island of Tenerife covers 203,000 hectares and has a resident population of 685,582. Approximately 12,500 hunting licenses are issued each year. There are 158,351 hectares currently available for hunting once security zones and protected areas have been excluded, resulting in a theoretical density of nearly 13 hectares per hunter. This excessive pressure has an impact on the following speci...

Dietary onion and garlic caused an increase in the level of liver and plasma total lipids in Coturnix coturnix japonica. This increase could be due to the effect of an increased feed intake, bile production, digestion and absorption that in turn caused an increased utilisation of dietary fat, increased transfer of dietary lipids to the liver and/or due to increased lipogenesis as such. However,...

An investigation of Vemo Herb® additive on the forage consumption rate in Japanese quail (Pharaoh breed) has been conducted. The experiment was carried out for 10 weeks with 52 female and 16 male sexually matured Japanese quails (Coturnix coturnix japonica) distributed in four groups: control group (without additive), first experimental group 4 mg*kg of live weight for 10 weeks; second experime...

PURPOSE To examine the possible correlation between a dysfunction of the daily rhythm of retinal dopamine (DA) and the development of a glaucoma-like disorder in an animal model, the al mutant quail (Coturnix coturnix japonica). METHODS The morphology and density of DA-containing cells labeled immunohistochemically with an anti-tyrosine hydroxylase (TH) antibody were correlated with the diurn...

Two-way selection for two-week packed erythrocyte volume (PCV) was practiced for four generations under two nutritional environments in the Japanese quail (Coturnix coturnix japonica). One environment was an iron, copper-"adequate" diet and the other was iron, copper-deficient "stress" diet. Response to selection was greater in both directions under the adequate environment than under the stres...

This study was conducted to determine the effects of various doses and particle sizes (micro or nano) of dietary zinc and zinc oxide on growth performance, serum enzyme activities, carcass characteristics, and zinc requirements in Japanese quails. A total of 576 day-old Japanese quails (both sexes) were housed in 36 deep litter floor pens. Birds received a basal corn–soybean meal diet that was ...
