Lakasa ti Sirib, DMMMSU Institutional Repository.https://lakasa.dmmmsu.edu.ph/handle/123456789/1730This study was conducted to: (a) identify the species of mites affected by Lima Bean leaf soap; (b) determine the efficacy of Lima bean leaf soap against mange in dogs; and (c) determine the most effective concentration of Lima bean leaf soap against mange in dogs. Twenty four (24) dogs positive of mange regardless of breed, age and sex were used in the study. They were distributed into four treatments and replicated three times with two (2) dogs per replicate using Randomized Complete Block Design. Preparation of Lima bean leaf soap was done at the Pharmacology laboratory. Before the application, skin scrapings were taken from three different sites on the animals to identify the species of mites present and determine their number. They were also classified based on the severity of lesions (light, moderate, severe). The experimental dogs were bathed once a week for six (6) weeks using the different preparations such as the following: TO - Plain soap T1 - 10% Lima Bean leaf soap T2- 15% Lima Bean leaf soap T3 - 20% Lima Bean leaf soap The data were tabulated using means and percentages. Analysis of Variance (ANOVA) was used to determine the significant effect of the treatments. Duncan’s Multiple Range Test (DMRT) was used to determine the differences among treatments and t-Test was used to compare pre-treatment and post- treatment mite count. Every after application of Lima bean leaf soap, post-treatment mite count was done on each dog using the same site from the pre-treatment mite count. Results showed that all the different concentrations of Lima bean leaf soap were effective against mange with light infestation and T3 and T1 were effective against mange with moderate infestation.en-USThesis
