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 aims of this study were the comparative study of probiotic, acidifier,antibiotic growth promoters and prebiotic on activity of humoral immune and performance parameters of broiler chickens.500 one day old male broilers (308 Ross strain) were divided into 5 groups: A, B, C, D and E. Each group with equal numbers of male included 4 replicates (25 chicks per replicate). Group A was as control ...

due to growing concerns about antibiotic resistance and the potential for a ban for antibiotic growth promoters, there is an increasing interest in finding alternatives to antibiotics in poultry production. therefore probiotic bacterial or fungal origin used as alternatives to antibiotic growth stimuli.to determine the effects of biomin (biomin contains of enterococcus faecium (a probiotic), fr...

13 worldwide have recommended stopping the use of antibiotic growth promoters (AGPs) and limiting the use of therapeutic antibiotics. Alternative methods are needed to control diseases and at the same time reduce the dependence on antibiotics, including improved biosecurity and disease management on farm level, vaccination programs and sustainable prophylactics intervention such as probiotics, ...
