Abstract
This study was conducted to investigate the pathophysiology of Haemonchus contortus infection in friesian calves. The animals were divided in two groups of four calves each. One group was infected, orally, with 500 Haemonchus contortus larvae per kg body weight and the other one as the worm-free control. Five weeks after infection they were all housed in metabolic crates and injected with {sup 125}I-bovine albumin, {sup 51}Cr-red cell and {sup 59}Fe-transferrin to study the albumin metabolism, the erythokinetic and ferrokinetic. The results showed that there was a significant reduction in the mean haematocrit values and an evidence of lower weight gains over the period of experiment in the infected calves compared with the controls. There was also a change in the distribution of albumin from the extravascular to the intravascular pool and a significant increase in the plasma and blood volumes of infected calves. The study of ferrokinetic showed an increase in the iron turnover and in the rate of iron utilization in the infected group. The blood and albumin loss by the gastrointestinal tract were similar in both groups. (author).
