摘要

This study was carried out to evaluate white blood cell count alterations (cell component) and the protein profi le (humoral component) in dual purpose calves, categorized as resistant and susceptible, after exposure to infested pastures. The study was conducted in 75 crossbred calves of both sexes (37 males and 33 females) from to dual-purpose operating units of the municipality Manuel Monge, Yaracuy state of Venezuela. Animals were divided into three age groups: 60 days, from 61 to 210 days, > 210 days and grouped according to their racial dominance as: Cebu, European, Carora. According to number of strongyle eggs per gram of feces (HPG) and hematocrit (HTO), animals were classified as: resistant type I (R1) with HPG 30%, resistant type II (R2 ) with HPG HTO 700 and> 30% and likely type II (S2) with HPG> HTO 700 and Cebu> European. The animals >210 days are the most resistant to nematode infection, 26% for R1 and R2 52% (p<0.05). Group R2 are also the most susceptible animals to other infections. Animals most susceptible to nematode infection are those with less than 60 days of age.
