Gastrointestinal parasites are one of the main sources of economic decline in sheep production around the world. Resistant sheep do not completely reject the disease; they only harbor fewer parasites than susceptible sheep and therefore have a lower fecal egg count. The present research was designed to evaluate microsatellite polymorphism in intron 5 of DRB2 gene and its correlation with H. con...

Gastrointestinal nematodes (GIN) severely affect small ruminant production worldwide. Increasing problems of anthelmintic resistance have given strong impetus to the search for alternative strategies to control GIN. Selection of animals with an enhanced resistance to GIN has been shown to be successful in sheep. In goats, the corresponding information is comparatively poor. Therefore, the prese...

Background: FAffaMAlanCHArt (FAMACHA) is a technique for treating the animals infested with gastrointestinal parasites by using clinical anaemia as determinant. The test based on assessment of colour variation conjunctival mucous membrane. Methods: In present study FAMACHA has been standardized and used to correlate anaemic status goats faecal egg count (gastro intestinal parasites) blood profi...

This study was conducted on four sheep breeds, Karakul, Kajli, Thalli and Kachhi for their natural resistance against Haemonchus contortus. After deworming, 13 animals of each breed were ingested with doses of 5000 L3 of Haemonchus contortus and then evaluation of each was made on the basis of fecal egg count (FEC), body weight, FAMACHA score and packed cell volume (PCV) at different days of in...

Gastrointestinal nematode (GIN) parasitism is the most important disease of small ruminants. Control is usually based on the use of chemical anthelmintics (dewormers); but these are prohibited from use in organic livestock, and the effectiveness of chemical anthelmintics in conventional operations is limited by high levels of anthelmintic resistance. Consequently, herbal dewormers are increasin...

The purpose of this research was to evaluate differences in parasite resistance of Barbados blackbelly ewes and Suffolk crossbred ewes. 40 ewes were used for this study; 20 were Suffolk crossbreds and 20 were Barbados blackbelly. Fecal egg counts (FEC) verified that there were zero internal parasites in the sheep at the start of the experiment. The sheep were placed on a previously grazed pastu...

A previously developed multiple regression algorithm was used as the basis of a stochastic model to simulate worm burdens in sheep naturally infected with Haemonchus contortus over five consecutive Haemonchus seasons (November to January/February) on a farm in the summer rainfall region in South Africa, although only one season is discussed. The algorithm associates haemoglobin levels with worm...

Background: Verminosis is the main limiting factor in sheep production. Its control has become more and more difficult because of resistance of gastrointestinal helminths to some active ingredients, which has led to search of alternative ways to verminosis control. Based on that, the goal of study was to evaluate the effect of homeopathy for verminosis control in sheep. Materials and Methods: T...

A longitudinal study was conducted on the differential faecal egg counts, haematocrits and body condition scores of sheep belonging to resource-poor farmers at Rust de Winter, Gauteng province, and Kraaipan, North West Province, South Africa. The animals were scored for level of anaemia using the FAMACHA method, an assay for the clinical evaluation of anaemia caused by Haemonchus spp. Periods o...
