the study was carried out to investigate the effects of camelia (camelina sativa l. crantz) variety (cs) oil or seeds on performance, meat quality, immunity and plasma metabolic profile in broiler chickens. the broilers (n= 2,080, cobb 500) were randomly allocated (sex ratio 1:1) for 32-day experimental periods (from 11d to 42 d) to 4 experimental groups: control (corn-soybean meal-full fat soy...

Feed applied at a rate 70% ad libitum from 14 21 days age 42 49 rabbits, 12 15 weeks Animals were fed prior following restriction. results showed stronger restriction, sex, their interaction broiler chickens than effect mainly obse...

A study was conducted to compare the growth performance and carcass characteristics of guinea fowl (GF) with Horro (HR) Tilili (TL) local chickens, Potchefstroom Koekoek (PK) exotic chicken. Seventy-five-day-old chicks from each genotype were used in 3 replications a completely randomized design. Commercial starter grower feed fed ad libitum during 20 weeks study. Daily dry matter intake g/bird...

Poultry are domesticated species of birds. Birds were domesticated for eggs (chickens, ducks and geese), meat (chickens, ducks, geese, turkeys, ostriches, emus, pigeons and game birds) or other uses including feathers (ostriches, ducks and geese), leather (ostriches), specific oils (ostriches, emus), cock-fighting (chickens) and homing (pigeons). Table 1 summarizes the approximate time when and...

The finding of tomacula, focal areas of sausage-shaped hypermyelination in peripheral nerves, is reported for the first time in avian riboflavin deficiency. Day-old, meat-type chickens were fed a riboflavin-deficient diet (1.8 mg/kg) and were killed on postnatal days 6, 11, 16, and 21, while control chickens were fed a conventional diet containing 5.0 mg/kg riboflavin. Tomacula were found in sc...

Commercial poultry operations involve four types of birds: broiler (meat producing) chickens, layer (table egg) chickens, turkeys, and ducks. Each type differs greatly in size and nutrient requirements. Breeder flocks for each of the species are a major part of the industry, and those flocks also have different nutrient requirements. Distinctly different diets are required for each species and ...

The 1,007,172-bp complete genome of Mycoplasma pullorum strain B359_6, isolated from domestic chickens, has been sequenced, assembled, and annotated.

The present study was carried out to evaluate the influence of increasing amounts of dietary polyunsaturated fatty acids (PUFA) and alpha-tocopheryl acetate (alpha-TA) supplementation on lipid oxidation of raw and cooked thigh meat stored under refrigeration. One hundred ninety-two female, 1-d-old, broiler chickens were randomly distributed into 16 experimental treatments resuIting from the com...

Consumers believe that quality of foods from organic production is superior to foods from conventional production. The objectives of the present study have therefore been to compare the quality of chicken meat from organic and conventional production on the basis of traditional meat quality criteria. The experiment was organized as a field study. Fresh organic broiler carcasses were purchased d...
