ABSTRACT
Broiler production is the most intensive branch of animal husbandry. This reproduction method is relatively quick, which allows for faster turnover of the resources involved. Recent addition of Probiotics with broilers feed shows good efficacy to improve its production. So this expermintal study aimed to examine the influence of the addition of probiotics in broiler diets on the economic outcomes of production. Total 120 broiler chicks were divided into three groups of fourty birds each (C, L, & H) fed with diverse concentrations of Probiotics. After the first week of treatment, the two groups (L and H) displayed a probiotics effect that manifested as a significant increase in body weight (BW) than the control group. After 28 days of treatment, the effect of high levels of probiotics (group H) demonstrated a significant increase of group (H) and either group (L) and control; meanwhile, both treated groups (L and H) exhibited a significant increase in feed intake (FI) compared with the control group. At the end of the 42-day study period, the data showed a significant increase in BW and FI in group H compared with both group L and the control group. Finally, the results found that the two groups L and H showed a significant increase in the most productive performance parameters at the most periods time. The results also endly indicated that the 1 g/kg dose (0.5 concentration) of probiotics provided for group H was better than the low concentration of probiotics provided for group L (0.25 concentration). The study concluded that extention of the investigated probiotic (L. delbrueckii) to broiler feed can plays an important role in improving the economic and productive efficiency of poultry farms, even though it represents only a small part of the total or variable cost of the production of poultry.
