“…The higher nutritive value of Aruana grass, mainly its higher CP content in the rainy season, might explain the lower levels of parasite infection for the animals on this treatment, and is in agreement with Barbosa and colleagues (2003). Higher dietary protein can improve sheep resistance to H. contortus (Abbott et al, 1986(Abbott et al, , 1988Bricarello et al, 2005). Nutritional status affects the development of the immunological system in young animals (Shaw et al, 1995;Kambara and McFarlane, 1996).…”

“…The parasitism leads to a negative nitrogen balance in the organism, mainly due to excessive loss of blood protein, and also of macro and micro elements and vitamins (Bowman, 2002). The blood drainage and nutrient losses induced by nematode infection can diminish performance and can be partially compensated by highly nutritive diet, mainly with high protein content (Abbott et al, 1986(Abbott et al, , 1988Bricarello et al, 2005).…”

The daily live weight gain (DLWG), faecal nematode egg counts (FEC), and packed cell volume (PCV) of Suffolk, Ile de France and Santa Inês ewe lambs were evaluated fortnightly for 56 days in the dry season (winter) and 64 days in the rainy season (summer) of 2001-2002. The animals were distributed in two similar groups, one located on Aruana and the other on Tanzania grass (Panicum maximum), in rotational grazing system at the Instituto de Zootecnia, in Nova Odessa city (SP), Brazil. In the dry season, 24 one-year-old ewe lambs were used, eight of each breed, and there was no difference (p > 0.05) between grasses for DLWG (100 g/day), although the Suffolk had higher values (p < 0.05) than the other breeds. In the rainy season, with 33 six-month-old ewe lambs, nine Suffolk, eight Ile de France and 16 Santa Inês, the DLWG was not affected by breed, but it was twice as great (71 g/day, p < 0.05) on Aruana as on Tanzânia grass (30 g/day). The Santa Inês ewe lambs had the lowest FEC (p < 0.05) and the highest PCV (p < 0.05), confirming their higher resistance to Haemonchus contortus, the prevalent nematode in the rainy season. It was concluded that the best performance of ewe lambs on Aruana pastures in the rainy season is probably explained by their lower nematode infection owing to the better protein content of this grass (mean contents 11.2% crude protein in Aruana grass and 8.7% in Tanzania grass, p < 0.05) which may have improved the immunological system with the consequence that the highest PCV (p < 0.05) observed in those animals.

“…In sheep given additional dietary protein, egg counts of Trichostrongylus colubriformis in faeces were significantly lower , worm expulsion significantly higher (Kambara, Mcfarlane, Abell et al,1993), and the animals developed a better resis- (Houtert, Barger, Steel et al, 1995). Abbot et al (1986) demonstrated that lambs fed a low protein diet were less able to withstand infections with Haemonchus contortus. The diet with low protein content decreased the prevalence of infection with Halipegus occidualis in snails (Keas, Esch, 1997).…”

“…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.…”

“…The situation is however complicated by the evidence that the nutritional status of the host may also affect its ability to mount an immunological response to larval challenge (Yakoob et al, 1983;Holmes, 1987;Parkins et al, 1989;Symons, 1989). The importance of protein status for the development of immunological competence has been indicated, and that the use of dietary supplements can reduce the severity of infection with Haemonchus contortus (Abbott et al, 1985(Abbott et al, , 1986(Abbott et al, , 1988 and possibly with Teladorsagia circumcincta (Brunsdon, 1964).…”

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.
