ArticleItem Open Access CHEMICAL EVALUATION OF AZOLLA AS POULTRY FEED INGREDIENT(TANUVAS, 2001-02) Parthasarathy, R.; Kadirvel, R.; Kathaperumal, V.; TANUVASquatic plants offer a relatively cheap altemative feedstuff as the composition of most of the aquatie plants with reference to protein and other nutrients is comparable to certain leguminous plants. Azolla, a floating fresh water fem, is capable of assimilating atmospheric nitrogen due to the presence of symbiotic algae in leaves (Moore, 1969) and has the potential to double its biomass with in a week. Under the suitable environment, about 70-80 tonnes of dry matter/ha/year is produced (Tally et al., 1977). Azolla has long been used as a fodder for pigs, ducks and fishes (Singh and Subudhi, 1978). In the present study, four different species of Azolla were chemically evaluated to find out its usefulness as a feed ingredient in broiler rations.ArticleItem Open Access CHEMICAL EVALUATION OF CERTAIN TOP FEEDS FOR SMALL RUMINANTS(TANUVAS, 1998-01) Parthasarathy, R.; Murugan, M.; Kathaperumal, V.; TANUVASIn recent years, much emphasrs has been given to the utilisation of tree fodder for livestock. The tree fodders are reported to be rich in protein and calcium but poor in fibre and phosphorus. The feed value of many of the commonly used tree leaves are yet to be critically studied. More over the information on seasonal variation in the nutrients in tree fodders is very much lacking. Data on this may be very helpful to assess the optimum season to lop tree fodder for livestock feeding. Hence in this study an attempt was made to document changes in proximate composition in some of the tree fodders commonly available in Tamil Nadu.ArticleItem Open Access EFFECT OF FEEDING TOP FEEDS ON THE PERFORMANCE AND NUTRIENT UTILISATION IN SMALL RUMINANTS(TANUVAS, 1998-01) Parthasarathy, R.; Murugan, M.; Kathaperumal, V.; TANUVASThe small ruminants are usually maintamed on range or degraded land, forest and on stubbles in cropped land after harvesting. During critical periods, roughly 60% of the feed requirement for small ruminants is met from top feed resources (Singh. 1981). The evaluation of nutritive value of tree fodder and its feeding m small ruminants has become very important in recent times particularly when the search for newer feed resources is going on. Therefore. a study was conducted to optimise the level of inclusion of tree fodder and its utilisation in small ruminants.ArticleItem Open Access INTEGRATION OF LIVESTOCK AND AGROFORESTRY SYSTEMS IN WASTELANDS DEVELOPMENT : PAST EFFORTS-AN OVERVIEW(Indian Veterinary Association Kerala, 1998-01) Kathaperumal, V.; TANUVASWasteland is defined as th land which is presently degraded and is lying unutilized except current fallows due to different constraints. Cultivable wastelands, having potentials for supporting vegetation and are not being properly utilised due to different constraints. Non-cultivable wastelands that have no potential to develop a végetable cover. India has total land mass of 329 million hectares. Ministry of agriculture estimated about half of the land area (175 million ha) are degraded. NWDB task was to bring 5 m.ha of land every year under fuelwood and fodder plantations. Low inputflow cost technology to achieve the objectives of NWDB is Silvipasture system.ArticleItem Open Access NUTRITIVE VALUE OF CERTAIN TOP FEEDS FOR SMALL RUMINANTS(TANUVAS, 1998-01) Parthasarathy, R.; Murugan, M.; Kathaperumal, V.; TANUVASShrubs and trees are the main source of roughage for goats. Though hundreds of species of trees are available for feeding of livestock, many of them are yet to be assessed for their nutritive value. The present study deals with the assessment of nutritive value of certain top feeds for small ruminants.ArticleItem Open Access STUDIES ON ECONOMICS OF UTILIZING AZOLLA ]N BROILER RATIONS(TANUVAS, 2001-02) Parthasarathy, R.; Kadirvel, R.; Kathaperumal, V.; TANUVASTwo feeding trials were conducted to study the economics of utilizing a water fem, Azolla sp. in broiler rations. Azolla was incorporated at 0,5,l0,15 and 20 per centlevels to replacea protein mix containing wheat bran and groundnut cake (53:47) up to 5 weeks of age in the first trial and to replace a protein mix containing wheat bran and fish meal (52:48) up to 8 weeks of age in the second trial. The birds receiving5 per centAzolla in both the trials performed significantly well (P < 0.01) and gave better economic returns viz. 15 and 16 per cent gain over other groups. The findings of this study indicated that the incorporation of Azolla as rt feed ingredient at 5 per cent level in broiler rations could provide promising economic returns.ArticleItem Open Access UTILISATION OF POULTRY WASTE AS FEED FOR HEIFERS(TANUVAS, Chennai, 1988-08) Murugan, M.; Kathaperumal, V.; Jothiraj, S.; TANUVASSeveral waste materials have been used in livestock feed to reduce the feed cost. Poultry excreta is one such waste available in plenty.
