Very good informative article about probiotics in the poultry industry

Thanks for this comprehensive overview about the role of probiotics in the poultry industry. While I agree with your conclusion that there is no more confusion regarding the probiotic concept; the main challenge now is how it can find routine application in commercial poultry. On the latter point it seems to me there is still a long way to go in terms of reproducibility of their effects. This is a paradox and makes commercial nutritionists and even vets sometimes skeptical to use them. Some of the problems have been traced to the intrinsic properties of the microbes themselves, some due to feed mill and farm operational constraints, some are just completely unknown factors. Among the way out is to train and retrain these helper microbes to target specific issues rather as all purpose agents. A probiotic or cocktail of microbes could be strong on nutrition while another is more supportive on health. It is highly unlike that we will ever have a formulation that can handle all poultry issues, may it it be gut problems or otherwise. Overall, research has to continue and at the moment I must say there is a lot of information coming out in peer review publications. This will ensure a future for this strategy. Again many thanks for the efforts.

Dear Dr.L . Kabir /Thank you very much/ I wish from you Evaluated This study
The Role of probiotics in the poultry industry

This study was conducted to investigate the effects of probiotic (Biomin Imbo®), vitamin(E) and their combination on growth performance , humoral immune response , to Newcastle disease vaccine , some biochemical , quality tests and histological changes in small intestine. A total of (300) broiler chicks one – day old (Hubard classic ) – unsexed were randomly divided into four equal dietary treatment groups, then each group was equally subdivided into (3) replicates. These four treatments:

Treatment (T1) : Basal diet without any addition (control group). Treatment (T2) : Basal diet + probiotic 1 gm/kg.
Treatment (T3) : Basal diet +vitamin E 250 mg / kg.
Treatment (T4) : Basal diet + probiotic 1gm/kgm + vitamin E 250 gm/kg .
The broiler chicks were fed with starter diet for the first (42) days and the finisher diet given between (42 and 49) days, and were exposed to cyclic heat stress (32±2 c?) from (600-1800 h/d) along experiment days . The chicks were vaccinated against ND at ( 10,20,30 )days old . Body weight, feed consumption, feed conversion ratio were weekly determined. Blood samples were collected from wing vein for blood analysis serological antibodies titer were determined using (ELISA) test in (19, 29, 39, 49) days old respectively. At (49) days of age (stress test, H/L, biochemical test, percentage weight of organs to body weight, histological examination, dressing percentage, microbiological tests to freezing chick meat) were measured. The results revealed the following :-

1) Chicks fed diet with combination (T4) showed significant (p
2) Treatments of adding probiotics (T2,T4) were significantly increased (p
3) Groups treated by adding vitamin E (T3,T4) revealed significant increase (p
4) The results showed significant improvement (p5) There is no significant differences (pPresented by /Dr.Ali alfayadh /Iraq

Please I need to ask about the physiological parameters should be measured to know the immune status after feeding with Probiotics and how I can measure it.

Probiotics is a science.. which is not complete, millions of bacteria (benificial) are there in the environment and the system. A viabale probiotic system to get consistent results has to combine probiotics prebiotics and symbiotics. Continuous research is required to update products sold of the shelf...
