Preliminary findings on gastro-intestinal parasitism in dairy calves in the Valle de Lerma (Salta)



Preliminary findings on gastro-intestinal parasitism in dairy calves in the Valle de Lerma (Salta)



Revista de Investigaciones Agropecuarias Serie 4, Patalogia Animal 10(1): 1-8



Faecal examination and larval culture showed that all of the 2- to 6-month-old dairy calves from 19 farms in the Lerma valley in northern Argentina had gastro-intestinal nematodes. Average epg was 291.8 but on 9 of the farms calves had counts above 300, which is considered to be the lower limit indicating pathogenic infections. Cooperia, Haemonchus and Ostertagia were the predominant genera.
