in order to evaluate the effect of polyunsaturated fatty acids on ascites incidence using this experiment was conducted 136 male one day (chicken ross 308) in a completely randomized design with 2 treatments and 4 replication and 17 chickens in each replicate. treatments includes: diet contain 4 % soybean oil (n3:n6:0.112) and diet include 5.5% poultry oil (n3:n6:0.201). birds were raised up to...

Introduction: Phasianidae is a non-migratory group of birds belonged to partridges family. One of the well-known species of partridge is Alectoris chukar, which is a medium-sized bird, larger than quails and smaller than pheasants. They are native to Asia, Africa, Europe and the Middle East and belong to the category of gallinaceous birds. Understanding the physiology and immunology of the lymp...

1. The concentrations of vitreous humour and plasma glucose were closely correlated in both healthy and fatty liver and kidney syndrome-affected chicks at time of death. 2. The values of vitreous humour glucose and lactate decreased rapidly after death, such that they were not reliable indicators of the presence of hypoglycaemia immediately ante mortem. 3. Hepatic glycogen was extremely low in ...

To test the hypothesis that inclusion of whole cereals in the diet of broiler chickens reduces the severity of a coccidial infection, the effects were investigated, in birds infected with Eimeria acervulina, of feeding a complete pelleted control food, the control food diluted with whole wheat (400 g/kg), or a diet in which ground wheat in the pellets was substituted with whole wheat (400 g/kg)...

Smaller guts and slow initial mass gains at stopover sites have led to the idea that digestive physiology limits refueling rates in migrating birds. We tested the digestive-limitation hypothesis in yellow-rumped warblers using food restriction to simulate infrequent feeding during migration, which may cause a reduction in alimentary tract mass. Restricted birds had small intestine, pancreas, an...

in order to investigate the growth curve of broiler chickens at line level, respectively 154 and 144 birds from two paternal lines a and b of a commercial broiler line were used. line a were selected several generations for low feed conversion rate and line b were selected several generation for high body weight. body weight was measured at 1, 4, 7, 10, 14, 17, 21, 28, 35, 42, 49 and 54 days of...

The purpose of this study was to investigate the influence of nine electrical stunning methods using various frequency and voltage combinations on the occurrence of engorged blood vessels in goose liver. Two hundred seventy Gourmaud geese (liver-type line SI 14) were slaughtered at 12 wk of age, in groups of 90 at three different times. Thirty birds each were subjected to one of the nine stunni...
