We studied the effect of BEDGEN 40™ SFA inclusion in the water on growth performance and hematological parameters of broilers from 1 to 42 d of age. The experimental design was completely randomized with 3 treatments that consists of C was the control without BEDGEN inclusion, T2 and T3 was treated by BEDGEN as supplements in drinking water (0.35 vs. 0.70 ml/1lt), respectively from 7 to 14 d and 21 to 28 d of age. Each treatment was 4 replicate and the experimental unit was a pen with 20 birds. All diets were based on corn, soybean meal, wheat, and included sunflower oil. From 1 to 42 d of age, inclusion of supplementation of BEDGEN 40™ SFA in drinking water increase body weight, weight gain, feed consumption (P<0.05) and improve feed conversion ratio, also exhibited significant effect on water intake at the last week of age and non-significant effect on blood lipids and PCV (P> 0.05) at day 21 and 42, during rearing period except blood HDL and Triglyceride at day 42. It is concluded that BEDGEN 40™ SFA supplementation were well utilized by broilers, at level of inclusion.

Aflatoxins, toxic metabolites produced by fungi in grains, cause economic losses and health problems in the poultry industry. This study investigates the protective effectiveness of xylo-oligosaccharides (0.4% and 0.8% g/kg) in mitigating the adverse effects of aflatoxin B1 (AFB1; 3 mg/kg) contamination in broiler diets. Experimental groups included: no supplement, 3 mg/kg aflatoxin, 0.4% xylo-oligosaccharide, 0.8% xylo-oligosaccharide, 3 mg/kg aflatoxin + 0.4% xylo-oligosaccharide, and 3 mg/kg aflatoxin + 0.8% xylo-oligosaccharide. Weekly live weight, weight gain, feed intake, feed conversion ratio, bursa of Fabricius weight, and internal organ weights were evaluated. Results showed that AFB1-contaminated feed reduced weekly and final weight, weekly and final weight gain, and weekly feed intake, while increasing the feed conversion rate. AFB1 also had detrimental effects on internal organ weights. Xylo-oligosaccharide alone did not significantly improve performance and increased abdominal fat. However, the combined use of AFB1 and xylo-oligosaccharides mitigated the negative effects of AFB1. The addition of 0.8% xylo-oligosaccharide was particularly effective in reducing the adverse effects of AFB1 in broiler chickens.

The spread of food-borne illnesses through poultry is a major issue in many countries, including Iraq. Bacteria can be present in poultry products if proper hygiene and sanitation protocols are not followed during production and processing. This research aimed to examine the impact of zeolite on performance, immunity parameters, and gut histology. A total 162 one-day old broiler chickens were randomly assigned to a control group and two natural zeolite-supplemented groups, each containing 54 birds (with three replicates/group and 18 chickens/replicate). The group (control) was without any additives, while the other two groups were fed diets containing 1% or 0.5% natural zeolite (NZ). The findings indicated that the groups receiving 1% and 0.5% natural zeolite (NZ) showed significantly (p<0.05) higher BW and BWG compared to the group (control). Feed conversion ratio was affected by 0.5% natural zeolite (NZ) supplement compared to the control. There were no significant differences in production index (PI), spleen (%), bursa of Fabricius (%), total WBC, lymphocytes, heterophils and H/L ratio between the natural zeolite (NZ) groups and control. The research revealed that zeolite may have a beneficial effect on gut histology in broiler. Therefore, using zeolite as a feed supplement for poultry could improve performance

The study was aimed to assess the impact of adding eggshells as calcium sources in broiler diets on carcass traits, meat quality, and chemical composition ,three hundred one-day-old broiler chicks were randomly designed CRD . Each treatment included five replications and each replicate containing twenty birds. The dietary of first treatment was control (0% eggshell) the second and the third treatments were eggshell powder as a replacement for limestone at 50% and 100%, respectively. .The chickens were fed a basal diet during the starting and finished periods. Ten broilers were chosen randomly from each treatment group and slaughtered at age 42 days to evaluate meat quality. The results showed that no significant differences (p< 0.05) between treatments regarding pre-slaughter in live body weight, carcass weight, and percentage of each carcass cuts weight, as well as immunological organs such as the spleen and bursa. However, a substantial difference in dressing percentage was observed. Except for pH, yellowness, and chroma, no significant differences were noticed in drip loss, cooking loss, lightness, redness, color ,tenderness. Meanwhile, the bird chemical composition treatments had no significant differences in moisture, protein, and ash percentages. However, there was a considerable change in fat %. Except for broilers' pH, yellowness, and chroma, the substitution of eggshell powder for limestone resulted in comparable carcass characteristics, chemical composition, and meat quality. However, there was a significantly differ in fat %. Except for broilers' pH, yellowness, and chroma, the substitution of eggshell powder for limestone resulted in comparable of some carcass characteristics, chemical composition, and meat quality.

This study was conducted to under seek the incidence of some neurotransmitters in drinking water and native medicinal flowers (Alecea Kurdica – Gule Hero and Chamomile) flowers as diet additives on body growth and immune of broiler. 720 one day unsexed hatched chicks will distributed into 12 treatments, each treatment with three replicates (20 chicks), as following: T0 (control -standard diet), [T1 (0.2 g Endorphin), T2 (0.2 g Dopamine) and T3 (0.2 g Serotonin)/ L drinking water], [T4 )0.5 kg Hero flower) and T5) 0.5 kg Chamomile flower)/ 100 kg diet], T6 )0.2 g Endorphin+0.5 kg Hero flower(, T7 (0.2 g Dopamine+0.5 kg Hero flower(, T8 )0.2 g Serotonin+ 0.5 kg Hero flower(, T9 (0.2 g Endorphin+0.5 kg Chamomile flower), T10 (0.2 g/ Dopamine+0.5 kg Chamomile flower), T11= 0.2 g/ L Serotonin/ L drinking water + 0.5 kg Chamomile flower/ 100 kg diet. The addition of neurotransmitters and native flowers additives as immune modulator had significantly affected on body weight, body weight gain and production index and led to to significant increase (P≤ 0.01) in relative weights of spleen, Bursa of fabricius, Thymus and antibodies titer against ND and IB diseases, also decreased the stress ratio which represented by heterophil/ lymphocyte (H/L) especially in T3 and T11.

This study aimed to survey the data collected from several commercial broiler farms in Akre region in order to evaluate the live body weight, carcass traits and their cuts, also to compare commercial projects of poultry in different farms in order to determine the best farm for rearing poultry. Statistical analysis was accomplished using the programme of Statistical Analysis System (SAS), also pairwise correlations among studied traits were determined.At 42 days of age, broilers' live body weight, and dressing percentage averaged 2276.50 g, and 76.52 percent, respectively, and the differences between the 4 farms used in this study were significant in all the mentioned traits. The differences in breast, thigh, back, neck and wing percentages were significant due to the farm and their averages were 36.75%, 25.21%, 18.78%, 5.82% and 8.19% respectively. The lymphoid organs including spleen % and bursa % were averaged 0.155% and 0.179% respectively, and the differences in all the lymphoid traits according to farm were significant. The higher coefficient of correlation (0.78) obtained between breast % and back % and was very highly significant, while the negative and higher value (-0.83) calculated between live body weight and back % and also was very highly significant. It can be concluded that a significant difference was found in all studied traits which may be due to differences in some factors including rearing system. Some of the correlations between each pair of studied traits were positive and highly significant, so to improve some traits, the breeder can focus on measuring other related traits.
