FAMACHA© method as an auxiliary strategy in the control of gastrointestinal helminthiasis of dairy goats under semiarid conditions of Northeastern Brazil

Abstract

This study aimed to evaluate the utilization of FAMACHA(©) method as an auxiliary strategy to use the individual identification for the selective control of gastrointestinal helminthiasis in naturally infected dairy goats. The experiment was conducted on 63 farms in the towns of Passagem, Quixabá and Cacimba de Areia, semiarid region of the Paraíba state, Brazil. Fifty animals were used on each farm, being visited tree farms per month, totaling 1800 animals, between May 2009 and April 2010. The animals received no anthelmintic treatment for at least four months prior to the farm visits. All animals were subjected to parasitological faecal collection, blood sampling for packed cell volume and the visual/selective exam of the eye colour through the FAMACHA(©) method. Larvae culture was performed in every assessment on each farm. Haemonchus sp. was the most prevalent helminth (80.1%) on larval cultures. The use of this method allowed a reduction of 79.2% on anthelmintic application in dairy goats. The FAMACHA(©) method proved to be a viable auxiliary strategy to control gastrointestinal helminthiasis of dairy goats from a resource-poor area in the semiarid region of the Paraíba state, Northeastern Brazil.

Control of sheep gastrointestinal nematodes using the combination of Duddingtonia flagrans and Levamisole Hydrochloride 5%

“…In this region, other researches too showed that that Haemonchus sp. was the most frequent helminth of sheep and goats (LIMA et al, 2010;VILELA et al, 2012b;MELO et al, 2013).…”

ANTHELMINTIC RESISTANCE IN SMALL RUMINANTS FROM THE SEMIARID OF PARAÍBA STATE, BRAZIL/Resistência anti-helmíntica em pequenos ruminantes do semiárido da Paraíba, Brasil

“…The most prevalent helminth species was Haemonchus spp., corroborating with Vilela et al (2012). Probably, this worm acquires faster resistance due to its high biotic potential and genetic variability, as well as hosting the allele that causes decreased susceptibility to a drug (BLACKHALL et al 1998).…”

“…The indiscriminate use of these drugs is one of them, which is mostly due to the producers' lack of knowledge, poor management practices and the ease of acquiring these drugs. According to Vilela et al (2012), high resistance to anthelmintics observed in studies conducted in semiarid regions of Northeastern Brazil may be due to the fact that deworming of all small ruminant herds four to six times per year is a common practice.…”

INFLUENCE OF STORAGE TIME OF Monacrosporium thaumasium PELLETS ON THE PREDATION OF INFECTIVE LARVAE OF SHEEP GASTROINTESTINAL NEMATODES

“…In the studied area, it is common for helminthic fauna of small ruminants are commonly composed of Haemonchus sp., Trichostrongylus spp., Oesophagostomum sp., and Strongyloides sp. (VILELA et al, 2012;VIEIRA et al, 2014). Vilela et al, (2016) observed the same helminth composition in sheep coprocultures in the semiarid environment of Paraíba, Brazil, with a higher prevalence of Haemonchus sp.…”
