Biochemical characterization of ingredients for supplementary fish feed formulation

K. Sivagami and J. Ronald

Abstract Fish diet production starts with ingredients selection and feed formulation. Selection of ingredients can be done from a wide range of choices, such as availability, cost and quality. The evaluation of feed ingredient is mandatory to nutritional research and feed development for carp culture. Usually quality of depends on the quality of feed ingredients used. High level of difference between common ingredients is well recognized and this will affect the nutritional value. Biochemical analysis constitutes variables such as; crude protein, carbohydrates, total lipids, ash, fiber and moisture contents. the results revealed that the highest percentage of protein, carbohydrate, fat, total fiber, moisture and ash content was 49.00, 83.00, 13.36, 6.30, 8.26 and 5.46% in silk moth powder, tapioca, rice bran, silk moth powder, corn flour and wheat flour respectively. Whereas the lowest percentage of protein (1.00%), carbohydrate (30.60%), fat (1.10%), fiber (1.94%), moisture (2.50%) and ash (2.96%) was recorded in tapioca, silk moth powder, corn flour, wheat flour and corn flour respectively. Key words: Ingredients, Biochemical analysis, Corn flour, Wheat flour, Silk moth powder

Growth performance and reprobiology of Macrobrachium rosenbergii feed with supplementation of Indigofera longeracemosa root extract

G. Raju M. Maridass and N. Subash

Abstract Macrobrachium rosenbergii de Man, 1879 is known as giant freshwater prawn. It is important to commercial species in the world wide. In the present study, observation of growth performance, reproductive biology and histological analysis of micro and macroscopical identification of development of ovary stages in M. rosenbergii fed with control diet containing 1%, 2% and 3 % of Indigofera longeracemosa roots extract for 60 days. The results of the present study, the all experimental diets fed with M. rosenbergii was a favorable growth performance of percentage of weight gain, specific growth rate and feed conversion ratio observed by p<0.005% significant, when compared with than the control diet (basal diet). The root extract was identified by active compounds were flavonoids, terpenoids, and phenolic compounds. The conclusion of the present study effects of I. longeracemosa roots supplementation in the control diet fed on M. rosenbergii reveal that improve growth, reduce the mortality rate, and enhances the reproductive performance of the in this species. Keywords: Medicinal plants, Ovary, histology; stunted growth; Macrobrachium rosenbergii
