“…This relationship could be useful in predicting the level of GIN infection in sheep flocks. This result is in agreement with the findings of Roberts and Swan (1981), Rinaldi et al (2009), and Amarante (2000) that reported a positive relationship between FEC and total GIN burdened with the highest relationship for Haemonchus sp. This depends on the various factors which include fecundity of species, age of worm, volume of ingesta, and host resistance (Rinaldi et al 2009;Wahab and Adanan 1992).…”

The factor of resistance level against GIN infection influences the composition of worm burden in sheep, where Amarante (2000) found that worm burden in Rambouillet sheep was higher than that in Florida native sheep even though they grazed in the same paddock and remained in the same flock.…”

“…Necropsy examinations confirmed the highest prevalence of the very prolific worm Haemonchus in the present study. This finding corroborates with those of other studies which showed Haemonchus as the most prevalent nematode in small ruminants (McKenna 2008;Gadahi et al 2009;Rinaldi et al 2009;Zeryehun 2012;Vanessa et al 2014). In contrast, Kumsa et al (2011) reported a higher prevalence of Trichostrongylus sp.…”

The prevalence of gastrointestinal (GI) nematodes and total worm burden of Damara and Barbados Blackbelly cross sheep was investigated among smallholder farms in Salak Tinggi district of Selangor, Malaysia. A total of 50 sheep raised in smallholder farms comprising of 27 Damara cross and 23 Barbados Blackbelly cross were categorized based on their age into young and adults. Fecal samples were collected and examined for strongyle egg count by using modified McMaster technique. Severity of infection was categorized into mild, moderate, and heavy, based on egg per gram (EPG). Five sheep were randomly selected and slaughtered to examine the presence of adult gastrointestinal (GI) nematodes through total worm count (TWC). Faffa Malan Chart (FAMACHA) score was used for investigation of worm load based on the degree of anemia. The study revealed an overall EPG prevalence of 88 %, of which 84.1 % had mild infection. There was a significant difference (p = 0.002) in EPG among the two breeds. Based on age, significant difference (p = 0. 004) in EPG was observed among Barbados Blackbelly cross, but not for Damara cross (p = 0.941). The correlation between severity of infection and the FAMACHA score was significant (r = 0.289; p = 0.042). Haemonchus spp. were the most predominant nematode found in the gastrointestinal tract, followed by Trichostrongylus and Oesophagostomum spps. EPG and TWC for Haemonchus were positively correlated, but not significant (r = 0.85, p = 0.066). From regression analysis, 73 % of the variability in TWC for Haemonchus could be explained by EPG. Thus, it can be concluded that FAMACHA score correlates well with severity of infection of a nematode and can be used to assess the strongyle nematode burden in the different sheep crosses.

“…It has also been listed among the top ten most common nematodes hampering production of goats and sheep in the tropics (Arosemena et al 1999;Horak et al 2004). Moreover, goats are more susceptible to worms due to their slowness to develop immunity (Ranaldi et al 2009). …”

Elephantorrhiza elephantina Bruch. Skeels. is used by farmers in the Eastern Cape Province to control helminths in goats. An in vitro study revealed efficacy of its fractions against adult Haemonchus contortus. This study was conducted to validate efficacy of fractions in vivo, on gastrointestinal nematodes in naturally infected goats. A total of 36 goats (18 males and 18 females) between ages of 8 and 12 months were used; these were randomly assigned to six treatments (A-F). For treatments A and B, goats received Prodose orange® (Albendazole 1.92 % m/v, closantel 3.94 % mv) at 2 ml/10 kg and distilled water at 0.5 ml/kg per os, respectively, whereas those under treatments C to E received aqueous fractions of E. elephantina at concentrations of 12. 5, 25, 50 and 75 mg/ml, dosed at 2 ml/10 kg. On days 1, 28 and 56, faecal samples were collected for faecal egg counts (FEC) and larval count, blood samples taken for packed cell volume (PCV) and body weights recorded to assess weight changes. The aqueous fraction caused highest the total faecal egg count reductions (TFECR) % of 81.7 %, 96.8 % and 98.6 % at doses of 25, 50 and 75 mg/kg, respectively, on day 56. This was comparable to the commercial drug Prodose orange®, which caused TFECR% of 94.9 % at the same time. The fraction also caused reduction of Haemonchus contortus and strongyloides larvae at all dose levels, but these were not significantly different (P > 0.05) to the negative control. There was an increase in body weights of animals at dose concentrations of 25, 50 and 75 mg/kg. Animals receiving the fraction had weight increases of between 3 and 4 kg by end of experiment (over 56 days), but those drenched with Prodose orange ® gained by less than 2 kg. The fraction also increased PCV levels at all doses on days 28 and 56 and this was comparable to the group on commercial drug. The reductions of FEC and worm larvae, as well as increase in PCVs are indicative that E. elephantina posses some antihelmintic properties against gastrointestinal parasites in goats. With a minimum dose concentration of 25 mg/ml being effective, this means that farmers can use little material. Increase in weight gain revealed in this study may indicate that the plant may have some nutritional value; further study is therefore called for to validate the plant for its nutritive value.
