Farmers of the poultry industry are seeking new and more efficient techniques to produce broilers quickly, without sacrificing quality, nutrition, or cost, as demand for rises in conjunction with human population. This study analyzed weight from day 1 harvest determine impact each daily weekly on final broilers. The experiment was conducted a conventional type housing. One hundred thousand male...

This study was aimed to determine protein and crude fiber digestibility by adding propionic acid in rations its effect on production carcass quality broiler chicken. research carried out using 180-day old chicks (DOC) chicken with Cobb strain. method used a completely randomized design (CRD) consisting of three treatments six replications for every treatment. The treatment this consisted of: T0...

A study with a duration of 42 days was conducted to evaluate the influence of fish oil inclusion on performance parameters, serum lipid content, antibody responses to sheep red blood cells (SRBC) and the composition of antigen and meat fatty acids in broilers. Two hundred and sixteen 1-day-old broiler chicks from a commercial hybrid (Cobb 500) were allocated randomly to four groups, which rece...

This experiment was conducted to investigate the effects of olive leaf (OL) on the performance, abdominal fat pad and some ileal bacterial population of Cobb broiler chickens. A total number of 400 day-old chicks were randomly distributed into floor pens and reared under the same condition until 14 days of age. On day 14, each pen was randomly assigned to one of the five experimental treatments...

The objective of this study was to evaluate the performance of male broiler chickens in the period from 21 to 42 days of age fed diets with increasing levels of sunflower meal (SM) supplemented with an enzyme complex (EC). A total of 1920 animals of the Cobb strain were distributed in a randomized block design in a 4 × 3 factorial arrangement (four SM levels and three enzymes utilization types)...

This study evaluated the effect of the intermittent light program on serum and brain melatonin concentrations, antioxidant enzyme activities, and homocysteine concentration in broiler chickens. A total of 60 one-day-old broiler chickens (Cobb 500) were distributed in three light-proof controlled rooms (20 chicks per room). All birds were reared in continuous light until 3 days of age. Then, chi...

This study was conducted to determine the effect of the air temperature variation on the mean surface temperature (MST) of 7to 35-day-old broiler chickens using infrared thermometry to estimate MST, and to study surface temperature variation of the wings, head, legs, back and comb as affected by air temperature and broiler age. One hundred Cobb broilers were used in the experiment. Starting on ...

The research paper presents the results of use a new probiotic feed additive containing dry culture lactic acid bacteria and fillers plant origin in diet young poultry. probiotics broiler chickens showed that outdoor cage keeping conditions did not significantly affect economic productive parameters poultry, while additives their provided an increase preservation Ross 308 cross by 6.0 4.0%, liv...

The aim of this study was to investigate the effect addition fungal solid-state fer-mented product (FP) enriched with gamma-linolenic acid (GLA) and β-carotene feed on haematological immunological parameters broiler chickens. Eighty 1-day-old COBB 500 chickens were divided into two groups. control group fed basic diets experimental received 10% FP, while amount diet reduced. FP produced during ...
