Prevalence of gastrointestinal nematodes in selected goat farms in bachok and kota bharu, kelantan

Gastrointestinal nematode infection is a major problem in goat industry worldwide including Malaysia. It is one of the most concerning problems in goat industry because it can affect the quality and production of the goat. The objectives of this study are to identify the genus of gastrointestinal nematodes of goats in selected goat farms in Bachok and Kota Bharu, Kelantan, to investigate the prevalence of gastrointestinal nematodes infection in the selected goat farms and to determine the odds ratio of the goats to be infected with gastrointestinal nematodes in the farm. Faecal samples that were collected from 73 goats in three farms in Bachok and Kota Bharu, Kelantan were subjected to McMaster technique, faecal culture method and genus identification of infective stage larvae, L3. All statistical analysis was conducted using R software for descriptive statistics and Fisher’s exact test to determine the odds ratio. As for the result, the gastrointestinal nematodes such as Haemonchus contortus, Trichostrongylus sp and Oesophagostomum sp were identified. The study demonstrates a prevalence rate of 0% for gastrointestinal nematodes mentioned above in Farm A. Meanwhile, Farm B revealed that H. contortus was the predominant genus (91%) followed by Trichostrongylus sp. (5%) and Oesophagostomum sp. (4%). As for Farm C, only H. contortus (100%) was revealed. The goats in Farm C were 0 0078 times more likely to get infected with
gastrointestinal nematode infection in comparisons to the goats in Farm A. In conclusion, the most prevalent gastrointestinal nematode in this study is Haemonchus contortus. The coinfection of gastrointestinal nematodes only occurred in Farm B. Farm C was most likely to get infected with gastrointestinal nematodes infection in comparison to Farm B. As a recommendation, sample size can be increased for future study to get more valid and accurate results.
