Interaction Between Lactic Acid Bacteria and Gastrointestinal Nematodes of Caprine Origin

To compare the level of parasitism with gastrointestinal nematodes in sheep and goats, several studies have been conducted (1 –3 ). They have generally shown that goats were more infected than sheep, as they exhibited higher worm burdens and egg excretion. This difference between two host species has been attributed not only to a difference in feeding behavior, but also to a lesser ability of goats to develop resistance to trichostrongylate infection (4 ) (In kids and lambs the greatest damage is observed from weaning until 1 yr of age; mature mothers, before and after parturition and during suckling, are affected [5 ]).
