DIAGNÓSTICO DE CONTROLE DE HELMINTOSES GASTRINTESTINAIS EM OVINOS: UM ESTUDO DE CASO NO NORDESTE GOIANO

Abstract

Gastrointestinal helminths are the main limiting factor for production of small ruminants, causing severe losses. The control method most used is the chemical, however, the incorrect and exacerbated use of this, contributed to the emergence of parasite resistance to anthelmintics. Because of this, it becomes It is necessary to use efficient management techniques and practices to control these parasites. So that the activity is economically viable, producing food that is safe to the consumer and environmentally friendly. The objective of this work was to raise a study bibliography that contextualizes the control of gastrointestinal helminths in sheep, as well as carry out a case study of a production unit located in the municipality of Campos Belos-GO. As a methodology, an explanatory case study was conducted in a sheep breeding property, during the period from August 2022 to February 2023. Stool samples were collected for OPG and application of the Famacha test. The property showed inefficiency in the control of helminths and the development of parasitic resistance to the anthelmintic used. Several factors are involved in the control of gastrointestinal helminths in sheep, such as handling, pastures, conditions environmental factors that favor or discourage the development of parasites, sheep genetics, nutritional and sanitary condition of the herd and the use of anthelmintics. Use only the chemical control in animals is not enough, it is necessary to adapt the property to an integrated control, in which all factors are considered in the fight against parasites. By offering animals nutritional management that meets their specific needs, implement appropriate pasture management practices in order to improve the quality of forage and reduce the parasite load, genetically select the most resistant animals parasites and discarding the most sensitive ones, in addition to performing selective deworming, it is possible to delay the development of resistance to anthelmintics and increase the effectiveness of treatments. These measures contribute to making sheep production more sustainable, economically viable, producing food safe for the consumer and environmentally correct.
