Evaluación del tiempo de reinfestación de parásitos gastrointestinales en bovinos de leche de la comunidad Santa Teresita de Guabug parroquia San Juan

Abstract

The objective of the present investigation was to know the reinfestation time of gastrointestinal parasites using Albendazole and which ones have a higher recurrence within the sampling. Fecal samples from 44 cattle were used, four samples were collected every 21 days, with results at day 0,21,42,63 and serological tests were applied: flotation method (gastrointestinal parasites), McMaster method (egg count per gram of feces). The data obtained were subjected to descriptive statistics by calculating standard deviation, maximum and minimum values. It was determined that there were no gastrointestinal parasites at 21 days after the application of Albendazole; however, a reinfestation was established at 42 days and a higher proportion of parasites at 63 days; the presence of 12 gastrointestinal parasite genera was also observed: nine of the genus Strongylidae; Cooperia, Paramphistomum cervi, Haemonchus contortus, Trichostrongylus, Oesophagostomum, Sin/Identify, Bunostomum, Ostertagia, Nematodirus, two of the genus Trichurida; Trichuris ovis, Capillaria sp and one with the genus; Ascaridida: Toxacara vitulorum. It was concluded, that the gastrointestinal parasite reported most frequently in the M1 was Sin/Identify with 25& in the M3 Haemonchus contortus with 31. 8% and in M4 S/I with 31.8% while the least frequently reported parasite in M1 was Paramphistomum cervi, Bunostomum, Ostertagia with 4.5% in M3 was Trichuris ovis, Capillaria sp with 2.3% and in M4 Trichostrongylus, Nematodirus, Toxacara vitulorum with 2.3. The socialization of a sanitary calendar is recommended for a more precise control of all parasites present.
