| dc.description.abstract | The present research was carried out to study the suitability of cultivation Super Napier (Pennisetum purpureum X Pennisetum glaucum) on tank bund fodder production system (TBFPS) and to compare its biomass yield, digestibility and cost of production with conventional fodder production system (CFPS). A tank bund of about 2.2 km length of a water tank of about 24 acres and the available cultivable land located at Livestock Farm Complex, NTR College of Veterinary Science, Gannavaram was used for cultivation of Super Napier. Binodal stem cuttings with a spacing of 90 × 60 cm between rows and plants were planted in both plain land and on the tank bund. Standard agronomic practices were followed for cultivation of the grass. The physical characters, growth, biomass yield, proximate composition, were measured. Digestibility of fodder was tested in 12 Murrah buffalo bull calves in a completely randomised design and the cost (Rs.) per kg Super Napier produced under CFPS and TBFPS was estimated. The height of the Super Napier plant (cm) was significantly (P<0.01) high at 15, 30, 60, 80 days at 1st cut and 2nd and 3rd cuts at 40 days intervals in TBFPS compared to CFPS. Significantly (P<0.01) higher number of tillers was observed for the Super Napier plant at all stages of growth except at 30 days in TBFPS compared to the CFPS. The number of leaves per plant was significantly (P<0.01) more at 15 days, 2nd and 3rd cuts in TBFPS compared to the CFPS. significantly (P<0.01) higher basal circumference diameter (BCD) (cm) of plant was observed for Super Napier fodder produced under TBFPS compared to CFPS at 15 days, 2nd and 3rd cuts. The leaf DM weight (kg) and leaf to stem ratio (LSR) was significantly (P<0.01) high from 1st to 3rd cut, while significant difference was not observed in the stem DM weight (kg) of Super Napier fodder except at 2nd cut which was significantly (P<0.01) high in CFPS compared to TBFPS. The average biomass yield (kg) of grass produced in CFPS and TBFPS was 25.13±1.8 and 26.4±1.7, respectively on fresh basis and 5.83±1.6 and 6.56±1.5 respectively on DM basis in a 5 m2 area and the difference was not significant. The plant height (cm), number of tillers, total number of leaves per plant, BCD (cm), leaf DM weight (kg), stem DM weight (kg), LSR and yield (kg) was maximum in the third cut compared to 1st and 2nd cuts in both the fodder production systems. Significant difference was not observed in dry matter (DM), moisture, organic matter (OM), crude protein (CP), ether extract (EE), crude fiber (CF), nitrogen free extract (NFE), total ash (TA), acid insoluble ash (AIA), calcium (Ca), phosphorous (P), neutral detergent fiber (NDF), acid detergent fiber (ADF), acid detergent lignin(ADL), cellulose, and silica content of Super Napier produced under CFPS and TBFPS. The green fodder and DM intake was significantly (P<0.01) high in buffalo bull calves fed with Super Napier grass produced under TBFPS compared to CFPS and the per cent of DM intake was 2.47 and 2.68, respectively for CFPS and TBFPS. Significant difference was not observed in the digestibilities of DM, OM, CP, EE, CF, NFE and TA of Super Napier fodder produced in tank bund and conventional fodder production systems in buffalo calves. The cost of production (Rs) per kg Super Napier under conventional and tank bund fodder production system without harvesting cost was 0.85 and 0.83 and with harvesting cost was 1.08 and 1.06, respectively. The present research concluded that Super Napier fodder is suitable for cultivation under TBFPS and comparable with the quality and quantity of fodder produced with CFPS. | en_US |
