“…That might be because the infection was not at clinical level, and therefore, anemia had not been formed yet. In addition, the humoral immunity mechanism was probably activated, so that the number of eosinophils in infected goats increased (Mandonnet et al 2005). Furthermore, the anemia was probably formed in the presence of bloodsucking parasites and as no distinction between species was made in this study, it is not known by which gastrointestinal nematodes the goats were infected.…”

The number of Eimeria oocysts per gram faeces (OPG) and number of gastrointestinal nematod (GIN) eggs per gram faeces (EPG) depend on some factors such as gender, season and production systems. In order to determine the Eimeria infection and some gastrointestinal nematode burdens in Maltese, Gökçeada and Turkish Saanen goats, OPG, EPG and packed cell volume (PCV) were investigated. Maltese breed tended to have lower parasite burden than other goat breeds (P≤0.05). In the first observation, the prevalence of Eimeria and nematodes was 100% in Gökçeada breed, while the prevalence of Eimeria and the prevalence of GIN infection were 98% and 78%, respectively, in Maltese. It was determined that OPG and EPG burdens were significantly affected by the age of goats and the sampling date (P≤0.0193). It was seen that OPG burden decreased as the goats get older (P= 0.0157), while EPG value varied by the age of a goat in an unsteady manner (P<0.0001). The PCV values determined in the breeds ranged from 0.23 to 0.31. Statistically significant and positive correlation coefficients were determined between OPG and EPG r= 0.20 (P= 0.0036), and between the PCV value and OPG r= 0.41 and PCV and EPG r= 0.37 (P<0.0001).

A specific breeding goal definition was developed for Creole goats in Guadeloupe. This local breed is used for meat production. To ensure a balanced selection outcome, the breeding objective included two production traits, live weight (BW11) and dressing percentage (DP) at 11 months (the mating or selling age), one reproduction trait, fertility (FER), and two traits to assess animal response to parasite infection: packed cell volume (PCV), a resilience trait, and faecal worm eggs count (FEC), a resistance trait. A deterministic bio-economic model was developed to calculate the economic values based on the description of the profit of a Guadeloupean goat farm. The farm income came from the sale of animals for meat or as reproducers. The main costs were feeding and treatments against gastro-intestinal parasites. The economic values were 7.69€ per kg for BW11, 1.38€ per % for FER, 3.53€ per % for DP and 3 × 10−4€ per % for PCV. The economic value for FEC was derived by comparing the expected profit and average FEC in a normal situation and in an extreme situation where parasites had developed resistance to anthelmintics. This method yielded a maximum weighting for FEC, which was −18.85€ per log(eggs per gram). Alternative scenarios were tested to assess the robustness of the economic values to variations in the economic and environmental context. The economic values of PCV and DP were the most stable. Issues involved in paving the way for selective breeding on resistance or resilience to parasites are discussed.

“…Pathogenic effects of the infection can range from depression in growth rate, diarrhoea, anaemia, to death depending on the severity. Mandonnet et al (2005) reported the impact of helminth infestation including H. contortus on the poor productivity of Creole goats in the humid tropics.…”

Reduction in livestock productivity from internal parasites remains a major problem including the roundworm Haemonchus contortus. Treatment is rather expensive in most resource poor regions of the world, and the use of genetically resistant genotypes have been advocated. Our preliminary study investigated the association of coat colour types and tolerance to H. contortus infection in West African Dwarf (WAD) sheep. Twenty-four WAD sheep (12 males and 12 females) representing five coat colour types were orally dosed with 1000 H. contortus third-stage infective larvae, and data were collected over a 3-week period on initial and post-infection body weight (IBW and PIBW), packed cell volume (PCV), total serum proteins (TSP), albumin (ALB), globulin (GLB) and faecal egg counts (FEC). Coat colour was significantly associated with tolerance to H. contortus infection (p B0.05). Brown mouflon (A m abbSs) sheep showed the highest mean PIBW, PCV and GLB (15.1691.76 kg, 30.6793.53% and 31.1790.54 g/dl), respectively, while brown sheep with extensive white markings (aabbss) had the highest mean TSP and ALB value (73.4092.02 g/dl and 44.4790.49 g/dl), respectively. Badger face (A bf aB-S-) sheep had the least mean values of PIBW, PCV, TSP, ALB, GLB and the highest FEC. There were no significant associations with sex and its interactions with coat colour on post-infection performances of WAD sheep in this study. Our results suggest that brown sheep can tolerate H. contortus infection better than other coat colour types, which may be due to the linkage between coat colour and resistance loci, linkage disequilibrium effects or resulting from pleiotropic effects deserving further study.
