This study was the first attempt to compare the prevalence of gastrointestinal parasites in goats in three different rearing systems. A total of 287 fecal samples were randomly collected from goats in three farms in Terengganu, Malaysia. The samples were processed by using sodium chloride floatation method and observed microscopically. Out of 287 goats, 280 (97.6%) were infected with gastrointestinal parasites. Goats reared under the intensive rearing system reported the highest prevalence of infection (99%), followed by extensive rearing system (98.3%) and the lowest prevalence was reported in the goats reared under the semi-intensive rearing system (96%). The following gastrointestinal parasites were identified in goats in accordance of predominant: Eimeria spp. (89.2%), Strongyloides spp. (45.6%), Strongyle spp. (20.6 %), Moniezia spp. (13.9%) and Trichuris spp. (8.4). Three species showed predominant in goats under the semi- intensive rearing system were Strongyle spp., Strongyloides spp., and Trichuris spp. with the percentage of 33.1%, 83.1% and 10.5%, respectively. Moniezia spp. was the highest in goats under the extensive rearing system which occurred at 26.7%, whereby Eimeria spp. was predominant under intensive rearing system with the infection rate of 99%. The finding suggested that the rearing system might not influence the occurrence of GI parasites in goats. Further study should be conducted to validate this finding.
Cryptosporidium, a protozoan parasite, can cause cryptosporidiosis which is a gastrointestinal disease that can infect humans and livestock. Cattle are the most common livestock that can be infected with this protozoan. This study was carried out to determine the prevalence of Cryptosporidium infection in cattle in Kuantan, Pahang, Malaysia and to find out the association between the occurrence of infection and 3 different ages of cattle (calves less than 1 year, yearling, and adult cattle). The samples were processed by using formol-ether concentration technique and stained by modified Ziehl Neelsen. The results showed that 15.9% (24/151) of cattle were positive for Cryptosporidium oocysts. The occurrence of Cryptosporidium in calves less than 1 year was the highest with the percentage of 20.0% (11/55) followed by yearling and adult cattle, with the percentage occurrence of 15.6 % (7/45) and 11.8% (6/51), respectively. There was no significant association between the occurrence and age of cattle and presence of diarrhea. Good management practices and proper hygiene management must be taken in order to reduce the infection. It is highly important to control the infection since infected cattle may serve as potential reservoirs of the infection to other animals and humans, especially animal handlers.
Helminths and coccidia are major causative agents causing parasitic infections in livestock production. The present study aimed to determine the prevalence and intensity of gastrointestinal helminths and coccidia in goats in Terengganu, Malaysia. A total of 227 goats which consists of 107 adult goats and 120 young goats were selected randomly from two farms located in Terengganu, Malaysia. Sodium chloride flotation technique was used to identify helminths eggs and coccidia oocysts. The number of eggs per gram and faecal oocysts count were determined by using modified McMaster technique. Out of 227 goats, 221 goats were positive for gastrointestinal parasites giving the overall prevalence 97.36%. The highest prevalence was recorded for Eimeria (89%) followed by Strongyloides (46.3%), Strongyle (18.1%), Monezia (10.6%) and the lowest prevalence was recorded for Trichuris spp. (9.7%). Coccidia oocyst counts were significantly higher in young goats as compared to adult goats while the Strongyle and Strongyloides egg counts were significantly higher in adult goats compared to young goats (P<0.05). The findings of this study suggested that good management practices and proper hygiene management are important to combat the infection so that there will be no case of parasitic infection among goats in the near future in Terengganu.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
