Lakasa ti Sirib, DMMMSU Institutional Repository.https://lakasa.dmmmsu.edu.ph/handle/123456789/1744This study was conducted to: 1) determine the phytochemical composition of Mahkota Dewa leaves; 2) identify the species of gastrointestinal parasites present in the experimental animals; 3) determine the efficacy of Mahkota Dewa leaf extract (MDLE) against gastrointestinal parasites of goats; and 4) determine the species of gastrointestinal parasites affected by MDLE. Dried and ground leaves stored in properly labelled and sealed plastic bags was brought to the Department of Science and Technology (DOST), Industrial Technology and Develpoment Institute (ITDI), Standards and Testing Division (STD), Manila for phytochemical analysis. Fifteen goats were used in the study. Prior to the treatment, fecal examination was done to identify the gastrointestinal parasites and determine the pre treatment EPG count. After the treatment, fecal samples were collected on the first, second, third, seventh, fourteenth and twenty-eight days and were analyzed at Institute of Veterinary Medicine (IVM), Parasitology Laboratory, Don Mariano Marcos Memorial State University, Bacnotan, La Union using McMaster and Modified Stoll’s Method of fecalysis. Five treatments replicated thrice were used in the study. The goats were distributed using the Complete Randomized Design (CRD). Treatments used were as follows: To No treatment (control) To+ 0.4 ml Albendazole (12.5%) per 10 kg bodyweight T1 3 ml MDLE per kg bodyweight T2 5 ml MDLE per kg bodyweight T3 7 ml MDLE per kg bodyweight The chemical composition of Mahkota Dewa after subjecting it to phytochemiccal analysis were as follows: tannins, saponins, glycosides, flavonoids, and sterols. Strongyle type spp., Strongyloides spp., and Moniezia spp. were the gastrointestinal parasites identified in the experimental animals. Treatment 2 (5ml MDLE) per kilogram bodyweight is effective against gastrointestinal parasites on the 14th day post treatment similar in efficacy to the commercial anthelmintic. Three ml (T1) MDLE is effective against Moniezia species.en-USThesis
