“…Anorexia in the course of ovine fasciolosis has been repeatedly reported (Boray, 1969;Sinclair, 1972;Berry et al, 1976;Hawkins et al, 1978;Sykes et al, 1980a). Inappetence has been associated with the entry of the flukes in the bile ducts, appearing only during the first phases in severe acute infection (Dargie, 1987).…”

Ten female Churra breed sheep were experimentally infected with 25 Fasciola hepatica metacercariae daily during six days. The animals were offered pelleted lucerne and water ad libitum. Feed and water intake was automatically recorded by computer monitoring of electronic balances. Liver damage caused by flukes was ascertained by measuring the activities of aspartate amino transferase, glutamate dehydrogenase and gamma-glutamyl transferase. Serum bile acids and glucose concentrations were also measured. Maximum plasma enzyme values were found at 10 weeks post infection. Plasma bile acid concentration increased from six to 13 weeks post infection. Glycaemia was decreased from the fourth week post infection until the end of the experiment. Total daily food intake decreased maximally between six and 12 weeks post infection. The number of meals per day and time spent eating and drinking decreased along the experimental infection. The rate of eating and drinking increased progressively. An association between anorexia and liver damage is suggested.

“…Appetite depression in sheep infected with Fasciola hepatica is well documented (Boray, 1969;Sinclair, 1972;Berry et al, 1976;Hawkins et al, 1978;Sykes et al, 1980a). Reduced daily food intake is a major factor impairing productivity (Dargie, 1987), but the relationship between the infection and the anorectic effects is still unclear.…”

“…The data obtained suggested that the supplemented diet could reduce parasite establishment compared with ewes at only grazing. However, some workers have indicated that the establishment of helminths, such as Oesophagostomum columbianum (Dobson et al, 1974), Haemonchus contortus (Abbott et al, 1985(Abbott et al, , 1986 and Fasciola hepatica (Berry et al, 1976), is not affected by the level of dietary protein.…”

Sixty Merino ewes during 140 days of pregnancy were naturally infected by strongylids at grazing, but 30 animals were provided a barley supplement furthermore (400 grams per head day" 1 ). Faecal samples were collected every 20 days for analysis and by means of faecal cultures the genera of strongylids present were identified. Body weight and body condition scores were also recorded every 10 days. Results showed that liveweight and body condition scores were higher in supplemented group than unsupplemented one during study. Unsupplemented ewes showed the higher strongylid eggs elimination during early pregnancy and periparturient rise in late pregnancy; and during whole experiment showed higher infection percentages than supplement fed group. However, supplemented ewes showed from 100 days of pregnancy higher values of strongylid eggs output. An increase in parasite establishment resistance of supplemented ewes is suggested and epidemiological implications will be discussed.

“…The nutrient utilisation and growth performance of host in response to trickle infection, which usually results in subclinical infection, had not been investigated thoroughly. The studies on interaction of fasciolosis and nutrient utilisation are pertained to heavy dose single infection (Akinbamijo et al, 1996;Berry and Dargie, 1976;Hope Cawdery et al, 1977;Mehra et al, 1999).…”
