Comparative Study of Probiotic, Acidifier, Antibiotic Growth Promoters and Prebiotic on Activity of HumoralImmune and Performance Parameters of Broiler Chickens
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 ...
متن کاملAntibiotic growth promoters.
Sir, I was dismayed to see that Phillips et al. were defending what nearly all microbiologists know are grave abuses of antibiotics— their continuous use in feed as growth promoters and the needless widespread use of broad spectrum agents (fluoroquinolones). This is despite their acknowledgement that ‘the more an antibiotic is used, the more likely are resistant populations to develop’ and that...

متن کاملAntibiotic Growth-Promoters in Food Animals
By Peter Hughes and John Heritage, University of Leeds, UK There has been a developing controversy surrounding the use of antibiotics as growth promoters for food animals. These drugs are used at low doses in animal feeds and are considered to improve the quality of the product, with a lower percentage of fat and a higher protein content in the meat. Other benefits of the use of antibiotic grow...
متن کاملEffect of Threonine Supplementation on Growth Performance, Metabolizable Energy, Morphological Changes and Immune Response in Broiler Chickens Challenged with Coccidia
This study was performed to investigate the effects of dietary threonine (Thr). level on performance, metabolizable energy, intestinal morphology, and immune system in coccidian–infected broiler chickens. The diets contained: 88%, 100% (Non challenged (NC) and challenged control (PC)), 112%, 124%, and 136% of Thr requirement according to Cobb 500 recommendation and fed during grower (pre challe...
