Abstract

Colibacillosis, caused by pathogenic Escherichia coli, is one of the main causes of economic losses among the poultry, worldwide. Losses occur at all ages, due to increase in morbidity and mortality, thus directly influencing the management and treatment costs. The characteristics of the disease and its aetiological agent have not yet been well defined. Due to the existence of antibiotic resistance and unavailability of effective vaccine, control of pathogenic Escherichia coli is a challenging task, hence an alternative control measure is needed. So, the present study was aimed to characterize the pathogenic Escherichia coli isolates and to control pathogenic Escherichia coli with prebiotics, as an effective feed additive It was observed that there was no significant difference between 0.1% and 0.2% levels of D-Mannose, but differed significantly at 0.4% level. However, there was significant difference between D-Mannose, MOS and lactose. Lactose proved to be not much efficient, when compared to the other two prebiotics. Hence, to conclude, D-Mannose would be the prebiotic of choice to be recommended to the poultry farmers to be added as feed additive from day-old to at least up to twenty weeks age of the poultry stock, as a routine, for effective control of the E. coli infection, in their farms

Conclusion

The superiority of mannose is not only on its drastic reduction of coliform count/ gm of caecal content, but also its convenience to be used in feed water or as oral dosing, because of its clear water-soluble nature. And it has been well documented that its action through competitive exclusion of E. coli might be the major contribution in the control of E. coli. As such, it assumes that it is acting both as prebiotic and probiotic. Also, all the possible drawbacks of any probiotic in the form of directly fed microbes (DFM) have been found to be absent in mannose, because it is an abiotic substance. Owing to multiple advantages of D-Mannose, it may be recommended to the poultry farmers to employ it as feed additive from day-old onwards at least up to twenty weeks age of the poultry stock (probable age of start of production), for possibly effective control of the E. coli infection, in their farms, as a routine
