The objectives of this study were to determine the effects of supplementation of grazing lambs with dried distillers grains with solubles (DDGS) or soybean hulls (SBH) on growth rate and nematode-parasite status. Over the course of four experiments in consecutive years, 312 lambs were grazed on the same four or six paddocks. Grazing lambs were allotted to one of three supplementation treatments...

Background: Haemonchosis is one of the major parasitic infestations in small ruminants. Haemonchus contortus a highly pathogenic parasite that localises abomasum affected animals and exerts its pathogenicity by blood-sucking activity, adversely affecting health productivity animals. In recent years, there widespread development anthelmintic resistance against spp. Therefore, sustainable strateg...

This study aimed to evaluate the genetic resistance of Pakistani goat breeds (Beetal, Teddy, Angora, Nachi) against Haemonchus contortus. In total, 13 animals of each breed, irrespective of sex, were selected. Following artificial infection with 5000 L3 (third stage) larvae of Haemonchus contortus to each animal, susceptibility and resistance of each breed was then assessed on the basis of body...

Organic meat sheep producers are limited by their access to and permitted use of synthetic drugs to effectively control internal parasites, and they are limited further still, by the narrow array of efficient alternative drugs available to them. The use of targeted selective treatments, for the control of parasites, e.g. treating only the lambs that cannot cope with infection, would be of inter...

Biological control of parasitic nematodes of livestock is currently under development and represents another tool that may be integrated into helminth parasite control strategies. This paper presents a brief introduction to commercial sheep farming in South Africa and currently available nematode parasite control methods. These include the FAMACHA clinical assay, strategies of pasture managemen...

Abstract Gastrointestinal nematode (GIN) infections affecting ruminants pose serious problems whenever management systems are deficient with inappropriate nutrition and sanitation. The Lebanese Baladi goat, reared under very challenging transhumant conditions, is recently being challenged nutrient availability due to the recent economic crisis. Therefore, prevalence of helminth parasites was st...
