Broiler performance to the end of the rearing period may be negatively influenced by delayed access to feed and water immediately after hatch. This study was conducted with 320 Ross 308 broiler chicks, to evaluate the influence of delayed access…
Microwave-processed full-fat soy beans for use in broiler diets. An experimental microwave oven, delivering microwaves of 1,3 kW (frequency of 2450 MHz), was used to process air-dry (9,13% moisture) and moistened (23,08% moisture) full-fat soy beans. The processed beans were…
The experiment was conducted to study the effects of organic selenium (Se-enriched yeast) and vitamin E (α-tocopheryl acetate) supplementation, alone or together, on the performance and antioxidant status of broilers fed diets enriched in n-3 PUFAs using fish oil. Day-old…
A study was conducted to investigate the effect of dietary supplementation of an organic acid, a probiotic or a prebiotic alone or the prebiotic combined with the organic acid or the probiotic on the performance and slaughter characteristics of broiler…
In order to determine the amino acid digestibility of artemia meal, five-week old male broiler chicks were given a semi-purified diet in which artemia meal was the sole source of protein. Apparent amino acid digestibility values of the assay diet,…
A 14-day battery trial using 336 four-day old male broilers was undertaken to compare the thermostability and efficacy of phytase produced in solid-substrate culture, a Solid Substrate Enzyme Product (SSEP), with phytase produced in liquid culture, a Liquid Enzyme Product…
An experiment was conducted using 96 individually caged male broilers between 49 and 77 d of age. One objective was to establish phenotypic relationships between some production traits [feed conversion ratio (FCR), feed consumption, residual feed consumption (RFC), relative weight…
One thousand two hundred and fifty sexed day-old broiler chicks obtained from a commercial hatchery were randomly divided into five treatment groups of 250 birds each (negative control, antibiotic and essential oil combination at three levels). Each treatment group was…
The present study was carried out to determine the effects of using dried rose dreg (DRD) as an alternative litter material for broiler performance and microbiological characteristics of litter. A total of 225 day-old broiler chicks was raised on pine…
A trial was conducted to investigate the effects of dietary vitamin E (E) and thyme oil (TO) supplementation on the growth performance, lipid oxidation, fatty acid concentration of tissues and the serum lipoprotein levels of male broilers. Two-hundred day-old Ross…
Two experiments were conducted to determine the response in performance, including uniformity and mortality, of two broiler strains to dietary protein content. In Experiment 1, 480 Cobb 500 and 480 Ross 788 day-old sexed broiler chickens were housed in cages…
The aim of the present study was to examine the effects of a herbal essential oil mixture on the performance of broilers produced by a young (30 wk) or an old breeder (80 wk) flock. One thousand and eight unsexed…
The objective of this study was to investigate the effects of dietary oils on growth performance of broiler chicks vaccinated with La Sota vaccine against Newcastle disease. One hundred and seventy five 1-week old Ross PM3 male broiler chicks were…
The present study was conducted to determine the effects of dietary metabolisable energy (ME) density and L-carnitine supplementation on the performance, carcass traits and blood parameters of broiler chickens. The experiment was designed with three levels of dietary energy (low,…
A study was conducted to compare the effects of an antibiotic growth promoter (flavomycin) and two herbal natural feed additives (garlic and thyme) with and without a xylanase-based enzyme complex in wheat-based diets on growth performance, carcass parameters, total plasma…
