    Comparison of Efficacy of Natural Yeast Cell Wall Polysaccharides (AntigenĀ®) Against Commonly Used Antibiotic Growth Promoters in Broiler Diets in Sri Lanka
    (Uva Wellassa University of Sri Lanka, 2012) Adikari, A.A.S.Y; Priyankarage, N; Silva, S.S.P; Nambapana, N.M.N.N
    Antibiotics have been widely used in animal production for decades in order to obtain high level of production and efficient feed utilization. Even though antibiotic growth promoters show positive effect on the performance of the livestock, use of antibiotics as growth promoters has caused some concerns in public health sectors. Transmission and the proliferation of resistant bacteria via the food chain and presence of harmful residues are the major concerns (Gunal et al., 2006) since Scandinavia and European Union have imposed a ban (Castanon, 2007). The need for developing alternatives is realized and many research studies have been started to identify suitable alternative feed additives that would reduce bacteria penetration and colonization in poultry and perform the same characteristics as the antibiotics. Many such as probiotics, prebiotics, exogenous enzymes and organic acids have been used with some success. Amongst many, yeast cell wall polysaccharides found to be consumer friendly alternative but the efficacy will vary with environment, management practices and feed. No comparative studies have been done in Sri Lanka. This study was conducted to determine the efficacy of an alternative, natural yeast cell wall polysaccharides which are having high affinity binders that can bind competitively to bacteria and prevent there binding to bowel cells, to colonize and caused infection. In the study that was compared with the commonly used antibiotic growth promoters in Sri Lanka

    Development of a Kurakkan (Eluesine coracana) Incorporated Low Fat Chicken Sausage
    (Uva Wellassa University, 2012) Weerasinghe, B.M.P; Wijesundara, W.M.N.M; Samaraweera, A.M; Ekanayaka, K
    The consumers' demand for low-fat or calorie products has significantly increased recently in an attempt to limit health problems, to lose or stabilize their weight, and to work within the frame of a healthier diet. The present study has been conducted to improve the nutritional and healthy value of traditional sausage production by incorporating Kurakkan or finger millet into low fat chicken sausage. Finger Millet contains amino acids, Lecithin and Methionine which help in bringing down cholesterol level by eliminating excess fat from Liver (Sivasankar, 2003). Its slow digestion indicates low blood sugar levels after a finger millet diet thereby reacting as a safer food, for diabetics (Kumari and Sumathi, 2002). Hence in this study attempts are made to develop a finger millet based sausage for the benefit of health concerned consumers

    Development of Protocol for in vitro Propagation of Gladiolus
    (Uva Wellassa University of Sri Lanka, 2012) Liyanage, L.P.H.; Jayasinghe, H.A.S.L.J; Alwis, L.M.H.R.
    Gladiolus, the queen of bulbous flowers belonging to family lridiaceaeis one of the most important and popular cut flower. Gladiolus occupies the first place in the international floriculture trade (Ghanie/ at. 2008). Gladiolus has long lasting flower stalks, attractive colors and numerous forms which make its higher consumer demand in the market. In Sri Lanka, only few farmers have tended to cultivate gladiolus as a commercial crop. Due to high vulnerability to the diseases and pests and unavailability of high quality disease free planting materials, flower growers dis-incline to cultivate gladiolus in their fields. Therefore, mass production of high quality planting materials and continuous supply are essential to promote the gladiolus cultivation in Sri Lanka. Gladiolus is vegetative propagated by corms and cormlets, which is a time consuming method due to very slow rate of mu Itiplication and disease factors (Torabi-Giglou and Hajieghrari. 2008). la vitro propagation methods become a viable alternative to the conventional propagation methods and are widely used for producing high quality disease free planting materials. There Fore, present study was undertaken to develop a protocol for lit vitro propagation of gladiolus by studying the effect of sterility and different hormone combinations for direct and indirect organogenesis
