    (Uva Wellassa University of Sri Lanka, 2016) Chandrarathne, G.M.A.G.; Wjesundara, R.R.M.K.K.; Rajapakse, R.P.V.J.
    The aim of this study was to evaluate the effectiveness of a selected medicinal recipe used in Ethno-veterinary practice to prepare a cream to cure swine dermatitis. The toxicity was evaluated using BALB/c mice model. The results were taken from elimination of Sarcoptes scabiei from naturally infested swine herds. All aqueous herbal preparations and oils were prepared separately using ethno veterinary recipes. These mixtures were mixed with an aqueous solution base. The cream contains 75% aqueous cream base, 20% aqueous herbal preparation mixture and 5% oil mixture. Skin irritation test, ear swelling and histopathological studies were performed for toxicity studies. Treatment effectiveness was determined by mite count of swine using Student t-test. In the skin irritation test, there was no signs of erythema and edema after application of once until 72 hours. With application of three consecutive days it could observe that there were no signs of erythema and edema for sensitization treatment. Therefore, the formulation was not exhibited signs of erythema and edema after application of the cream. Biopsy samples were collected after 72 hours of application the cream. Histopathological evaluations were carried using light microscopy. There was an inflammation on treated ear. Measurement were taken from ear thickness to evaluate the swelling of ear. Observed mice did not show significant difference between the ear swellings. Mite count of pigs in day ten was significant than the other days. The cream has to be applied at least ten days to get better results. The cream can be used for curing swine dermatitis.

    A Study on Gastrointestinal Parasitism of Nematode and Eimeria spp on Cattle and Goat Units in Mahaberiyathanna Farm
    (Uva Wellassa University of Sri Lanka, 2010) Kumaragama, K.M.K.R.; Rajapakse, R.P.V.J.; Samaraweera, A.M.; Wijesundara, K.
    This paper reports the prevalence of gastrointestinal nematodes and Eimeria spp in goat and cattle units in NLDB farm, Mahaberiyathanna from March to June 2010. Eggs (EPG) and oocysts (OPG) in a gram of fecal matter and larval counts were obtained from fecal samples of 40 cattle and 80 goats. Goats and cattle were divided into 3 age groups as < 6 month, 6 - 12 month and > 1 year and results were analyzed accordingly. Three genera of gastrointestinal nematodes namely Haemonchus, Trichostrongylus, Oesophagostomum and Eimeria alljevi and Eimeria arloingi of genera Eimeria were identified in the goat unit, while the Haemonchus and Oesophagostomum were identified in cattle. Eimeria spp were dominant (P<0.05) in goats below 6 month of age and Strongyl spp were dominant (P<0.05) among above one year age group in both cattle and goat units. Goat and cattle farm EPG and OPG value increased significantly (P<0.05) with the rainfall. The goats were sent for grazing while cattle were stall fed and, this can be the reason for the severity of gastrointestinal parasites in goats compared to cattle unit. These observations serve as a useful guide for strategic control of gastrointestinal nematodes and Eimeria spp in Mahaberiyathanna NLDB farm.
