“…Dentre os efeitos deletérios gerados pela infecção pelo H. contortus em pequenos ruminantes, destacam-se diminuições nas concentrações séricas de proteínas totais, notadamente a albumina (BLACKBURN et al, 1992). Os cordeiros apenas suplementados com selênio e vitamina E (G4), apesar de terem recebido, durante todo o período experimental, uma dieta com baixo teor proteico, exibiram um incremento na produção de proteínas totais e de albumina aos 60 e 80 dias (Tabela 1).…”

“…In contrast, there are few studies on goats and they provide equivocal results. Blackburn et al [2,3] did not observe any effect of protein supplementation on the worm burdens in young meat producing goats infected with H. contortus. In contrast, in growing goats parasitised with T. colubriformis, Singh et al [23] showed a reduction in FEC and worm burdens in animals receiving a supplemented diet.…”

“…Indeed Bown et al [4] showed that gastrointestinal nematode infections induce protein losses rather than energy deficiency. However, there are very few studies in this field on goats and their results are equivocal: in growing goats, Blackburn et al [2,3] recorded an improvement in resilience with protein supplementation but no effect on resistance whereas Singh et al [23] reported an enhancement of both resistance and resilience using a diet with cottonseed meal supplementation (reduction of faecal egg count and worm burden and no detrimental effect of parasitism on live-weight gain in young goats). It is worth underlining that these studies were performed with young, growing goats and that in fact, no studies have examined the influence of protein supplementation in dairy goats.…”

The effect of two levels of dietary protein on resistance and resilience of dairy goats experimentally infected with Trichostrongylus colubriformis: comparison between high and low producers

-Numerous studies have examined the interactions between protein nutrition and the response to nematode parasitism in sheep, but very few in goats. Compared with other ruminants, goats are less resistant to nematode infection. In addition, in dairy goats, high producing animals have been shown to be less resistant and less resilient to infection compared to low producing ones. The objective of the present study was to examine the consequences of protein supplementation on both resistance and resilience of dairy goats to nematode trickle infection, taking into account the initial level of milk production of the animals. During a 14-week period, 40 milking goats received a high protein (HP) diet supplying 130% of the protein requirements, and 38 goats were fed a intermediate protein (IP) diet (120% of the protein requirements). In addition, half of each group was given a weekly trickle infection with Trichostrongylus colubriformis larvae, the other part of the flock remained non-infected. Faecal egg counts (FEC), eosinophil counts and pathophysiological data (urea, albumin and inorganic phosphate concentrations in the serum) were measured twice a month. Milk production data (milk yield, protein and fat contents) were also recorded every 15 days. The results showed that FECs were lower (p < 0.05) and eosinophil counts higher (p < 0.05) in the animals receiving the HP diet suggesting that resistance was enhanced by protein supplementation. Meanwhile, milk parameters (related to resilience) were not affected by the level of protein in the diet when considering the whole groups. In contrast, in the high producing goats, the milk production and milk composition parameters were improved with the HP diet. To conclude, we have seen that the expression Vet.

“…However, the relationships between dietary protein and parasitism have been insufficiently investigated in goats with only a limited number of trials being reported. The first trials investigated interactions between plane of nutrition and H. contortus infection (Blackburn et al, 1991(Blackburn et al, , 1992 confirming that a high plane of nutrition can result in improved resilience. However, it did not determine if these differences were the result of protein level or the combined effects of higher energy, protein and voluntary feed intake (VFI).…”

Parasitic nematodes of the digestive tract remain one of the main constraints to goat production both in temperate and tropical countries. The usual mode of control of these gastrointestinal nematodes (GIN) based on the repeated use of anthelmintics is now strongly questioned because of the increasing development of resistance to these molecules. Among the alternative methods to anthelmintics currently available, the manipulation of host nutrition in order to improve the host resistance and/or resilience to parasitic infections seems to represent one of the most promising options to reduce the dependence on conventional chemotherapy and to favour the sustainable control of gastro intestinal nematode infections. This paper will review the available information on the interactions between nutrition and nematode parasitism in dairy or meat goats both in temperate and tropical conditions. It will refer to quantitative aspects of the diet (influence of the protein and/or energy parts) as well as to qualitative components (effects of plant secondary metabolites on worm biology) and will discuss the specificities of goats in regard of theses interactions.
