Studies on the effect of some probiotics in rabbits

الملخص EN

Sixty five recently weaned White New Zealand rabbits were used in this study to determine the effect of the probiotic supplementation in drinking water on their performance and prevention of coli enteritis which causes severe economic losses in pre and post weaning period.

5 rabbits subjected for postmortem and bacterial isolation, while 60 rabbits were divided into 4 equal groups control, infected (G I), probiotic (G II), and probiotic infected (G III).

The probiotic (G II, G III) groups were supplied by (E.

faecium) in drinking water entire experimental period (1gm / 3lit water), while the infected groups (G I, G III) were infected orally with Enterohemorrhagic E.

coli (EHEC) O157 : H 7 strain.

The results showed that using probiotic have good effect on increase (body weight gain, carcass yield, total protein and globulin), and decrease (cecal pH, Malondialdhyde, and E.

coli colonization in the intestinal tract).

The used probiotic improved the rabbit production and could be used as alternative to antibiotic as prophylactic and control of enteric diseases.
