Sound exposure effects have been investigated by broadcasting a group of broilers with sound of Quran verses (Group B) whereas the other group is the control broilers (Group C). The growth rate comparisons in terms of weight and raw meat texture measured by shear force have been investigated. Twenty-seven broilers were randomly selected from each group on Day 24 and weight measurement was carri...
The objective of this study was to determine the influence of Ca source [highly soluble calcified seaweed (HSC) or limestone], phytase supplementation, and dietary levels of Ca on bird performance and mineral digestibility (Ca and P) during a necrotic enteritis (NE) episode. Cobb 500 male broilers were weighed and randomized into 8 treatment groups (9 pens/treatment; 30 birds/pen) at day of hat...
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 experiment was conducted to investigate the effect of different levels of saccharomyces cerevisiae cell wall on performance, carcass traits and intestinal morphology in broilers. in this experiment 240 ross- 308 broilers were used in 4 treatments, 5 replicates and 12 bird in each replicate in a completely randomized design for 42 days. the treatments included: 1) control group (without sac...
This experiment was conducted to evaluate the effects of different levels of nettle (Urtica dioica) a medicinal plant in starter and grower feeds on performance, carcass traits, blood biochemical and immunity parameters of broilers. A completely randomized design was used with 324 broilers (Ross-308) divided in nine treatments and three replicates (with 12 birds in each replicate) 1 to 42 days....
The effect of a dietary phytogenic feed additive (PFA) inclusion level in mucin monosaccharide composition, mucosal morphometry and mucus histochemistry along the broiler intestinal tract was studied. Cobb male broilers (n = 525) were allocated into five experimental treatments that, depending on the type of addition in the basal diet (BD), were labeled as follows: C (BD based on maize-soybean ...
Sawdust and wood shavings are the major industrial waste from its related industries. Steam-explosion treatment enhances utilizable fiber fraction in pinewood particles. This study investigated effects of adding up to 2% steam-exploded pine particles (SPPs) diets on growth performance cecal microbiome broilers. On 8th day age, 216 Ross 308 broilers were allocated three treatments 72 broilers/gr...
this experiment was conducted to investigate the effects of different levels of oxidized fat (yellow grease) and copper sulfate on performance, carcass traits, blood metabolites and immune cells of broilers. this study was carried out as a 3 × 2 factorial experiment with 3 levels of oxidized fat (0, 2 and 4%) and 2 levels of copper sulfate (0 and 300 mg/kg) in 6 treatments, 3 replicates and 12 ...
Effect of different levels of date waste were studied on performance and immune responses of 240 Ross 308 broiler chicks in a completely randomized design with 5 treatments and 4 replicates and 12 birds in each replicate. The whole date waste were analyzed for chemical compositions and gradual levels of 0 (control), 5, 10, 15 and 20 percent of that were included into the diets which fed broiler...
