  Salmonella contamination of broilers is a major problem that faces the poultry industry in Kuwait and elsewhere since it affects the consumption of poultry meat. Therefore, utilization of different control measures leading to the reduction of Salmonella contamination is an important task for the broiler industry and the public health authorities in Kuwait. An important strategy is to significantly reduce the levels of Salmonella at the farm level and improve the manufacturing practices in the processing plant to prevent the risk of cross contamination. In our Department, different treatments have been used to control the contamination of this pathogen at the farm level, one of which is presented in the current study. The objective of the current study is to determine the effect of using different organic acids in the drinking water during the feed withdrawal period on reducing Salmonella in broilers. One hundred and twenty broiler chicks were originally housed in each of 36 floor pens. At the time of feed withdrawal, the pens were divided into four groups of nine pens each and were used for one of four treatments. These treatments included the control group and received untreated water, the second group received water containing 0.1% acetic acid, the third group received water containing 0.1% formic acid and the fourth group received water containing 0.1% lactic acid for a period of eight hrs. This study was repeated both in the summer and winter seasons. The prevalence of Salmonella on the chicken body, ceca and in the crop was determined before and post treatment at the farm and then at the processing plant. In addition to reducing body Salmonella contamination significantly (p<0.05) post treatment at the farm, in both seasons, it was found that acid treatments, in the summer season, significantly (p<0.05) reduced Salmonella contamination in the carcass at the processing plant from 36% (control) to 16, 13, 13% for acetic, formic and lactic acid treatments, respectively. In the winter season, both formic and lactic acid treatments reduced Salmonella contamination in the carcass at the processing plant and the reduction was significant (p<0.05) for formic acid treatment. It can be concluded that using organic acids in the water during the feed withdrawal period, both in the summer and winter seasons, can be beneficiary in reducing broiler Salmonella contamination both at the farm and at the processing plant.

  Background and Objective: Generous use of antibiotics in the broiler diets is a common practice in the broiler industry for promoting growth and enhance the immune responsiveness. Subsequently, resulted in occurrence of resistance amongst pathogens and potential for residuals in broiler chicken body tissue. The current study was carried out to evaluate the impact of various levels of black cumin seeds (BCS) dietary supplementation on growth performance, mortality and immune response of broiler chickens. Materials and Methods: Two-hundred fifty-five, one-day old Cobb 500 broiler chicks were randomly assigned into three treatment batteries with five replicates of 17 chicks each. Three levels of black cumin seeds (0, 1 and 3%) were fed in the diets of the test broilers, in which the group with 0% served as a control. Results: Diets supplemented with black cumin seeds significantly (p<0.05) improved the growth performance parameters such as body weight, body weight gain, feed consumption, feed efficiency and mortality percent as compared to the control group. In addition, diets supplemented with black cumin significantly (p<0.05) increased the bursa and thymus weights and improved antibody production, as well as the immune-responsiveness of birds. Conclusion: Dietary supplement of black cumin seeds at the level of 1 and 3% may improve production performance and potential for improving immune-responsiveness of broiler chicken.
