ArticleItem Open Access CHEMICAL COMPOSITION OF WHOLE CROP AND DIFFERENT PARTS OF HYDROPONIC MAIZE FODDER(2019-12) Vijayakumar, MP; Thirumeignanam, D; Chellapandian, M; TANUVASA study was conducted to quantify the nutrients in whole crop and different parts of hydroponic maize fodder. Fodder maize was cultivated and harvested in eight days in the TANUVAS Hydroponic greenhouse production plant. Samples of whole crop, leaf and stem and root portions were collected and analysed for proximate composition. The leaf and stem component had higher crude protein and crude fibre contents whereas in roots, crude fat and nitrogen free extract contents were higher. Hydroponic maize fodder whole crop contained high protein, fat and soluble carbohydrates but low fibre than the traditionally field cultivated fodder maize. The nutrient content of hydroponic maize fodder was found to be high and suitable for feeding ruminant livestock.ArticleItem Open Access Effect of Nano Zinc Supplementation on Production Performance, Immune Response and Carcass Characteristics in Japanese Quail Broiler(2023-09) Arulnathan, N; Chellapandian, M; Geetha, K; Thirumeignanam, D; Vijayakumar, MP; TANUVASABSTRACT Background: Nano-technology is currently an emerging field and giving promising results with cost economics in the poultry nutrition sector. A study was conducted to investigate the effects of nano Zn supplementation on production performance, immune response and carcass characteristicsin Japanese quail broiler. Methods: Synthesis of zinc oxide nano-particles was carried out by chemical method and characterized by standard techniques. Day old Japanese quail chicks (n=240) were randomly allotted in four treatment groups for feeding trial and fed with basal diet and source of zinc viz. for T1 inorganic zinc oxide, for T2, T3 and T4 nano zinc oxide was used at 75%, 50% and 25% levels of BIS recommendation for Zinc. Production parameters, immune response, carcass characteristics and cost economics were studied. Result: Based on the data analysed T3 and T4 showed significantly (P<0.05) improved performance in production parameters like body weight gainand cumulative feed conversion ratio than T1 and T4. HI, titer value and carcass characteristics data also showed similar trend.ArticleItem Open Access Effect of Supplementation of Graded Levels of Tanniferous Feeds on the Nutritional Quality of Hedge Lucerne Silage for Goats(2020) Thirumeignanam, D; Chellapandian, M; Arulnathan, N; TANUVASThe effects of supplementation of graded levels of Acacia nilotica pods on the characteristics and in vitro rumen fermentation of hedge lucerne (Desmanthus virgatus) silage were evaluated in this study. Laboratory-scale silages were prepared in triplicates by adding Acacia nilotica pods (ANP) equivalent to 1, 2, 3, 4 and 5 percent (w/w) of tannin to fixed quantity of hedge lucerne forage. Following 45d of ensiling, the silage characteristics, in vitro nutrient digestibility, total gas, methane and ammonia production were evaluated. The results revealed that there was an increase (P<0.01) in the DM and total VFA contents of the silages accompanying a reduction (P<0.01) in pH value, CP andammonia-N contents at higher tannin levels. However, in-vitro CP degradability (P<0.01) and methane production (P<0.05) were significantly reduced in hedge lucerne silage supplemented with 3% tannin equivalent of ANP than 5% tannin level. It was concluded that supplementation of graded levels (up to 5%) of tannin equivalent of Acacia nilotica pods in hedge lucerne silage improved the quality of silage, but reduction of in vitro ruminal protein degradability and methane gas production was possible only at 3% tannin equivalent level.ArticleItem Open Access NUTRITIONAL EVALUATION OF PROSOPIS JULIFLORA PODS FOR SHEEP(IJSET Journal, 2019-01) Chellapandian, M; Thirumeignanam, D; TANUVASThe chemical composition of Prosopis juliflora pods was estimated and the digestibility of its nutrients was analysed in adult sheep. The pods contained 91.74% DM, 86.13% OM, 12.96% CP, 22.53% CF, 1.67% EE, 57.23% NFE, 5.61% TA, 42.82% NDF, 30.17% ADF, 2.55% ADL, 0.59% Ca and 0.23% P. The DCP and TDN contents were 9.09% and 63.77% respectively. The nutrient supply from the pods was observed to be adequate to support maintenance and growth requirements of adult sheep.
