    NUTRITIONAL EVALUATION OF JACK (Artocarpus heterophyllus) FRUIT RESIDUE SILAGE AS LIVESTOCK FEED BY CHEMICAL, IN VITRO AND IN VIVO METHODS
    (KARNATAKA VETERINARY, ANIMAL AND FISHERIES SCIENCES UNIVERSITY, BIDAR, 2018-07) ARUN P. NATH; Dr. T. M. PRABHU
    An experiment was conducted to study the nutritional value of jack (Artocarpus heterophyllus) fruit residue silage in terms of chemical composition, intake, digestibility and efficiency of utilization in lambs fed straw based diet. Twelve Mandya lambs of about 3 to 6 months of age with body weight ranging from 8.5 to 10.3 kg were divided into two groups of six each in a completely randomized design. Twelve weeks feeding trial and six days digestion trial at 8th week was carried out. First group (T1) of lambs were fed with finger millet straw as the sole source of roughage and compounded feed mixture (CFM), while the second group (T2) were fed with jackfruit residue silage to partially replace (25%) FMS as a source of roughage and CFM. Chemical analyses (%) revealed that the JFRS has higher CP (8.77 v/s 3.35) and EE (1.91 v/s 0.79) and lower TA (6.46 v/s 8.51), NDF (34.08 v/s 71.84), ADF (27.88 v/s 46.46) and ADL (1.06 v/s 3.83) contents as compared to FMS.

Cumulative gas (ml / 200mg DM / 24 h) production and energy density (ME, MJ/kg DM) for JFRS was higher than the FMS (61.66 v/s 35.33; 10.80 v/s 7.01). The IVDMD or TDMD and NDFD were found to be 87.42% and 51.91%, respectively. There was no significant difference in total DMI (as g/d and % BW) between the treatment groups. Significant (P≤0.05) difference was observed in overall mean CPI, NDFI and ADFI (% BW) between the treatment groups. The ADG (g per day) and FCR (g DMI / g BW gain) for T1 and T2 groups were statistically non-significant. The mean apparent digestibility (%) of nutrients (DM, OM, CP, NDF and ADF) and the per cent DOMDM were also comparable between the treatment groups. JFRS has a potential nutritive value, hence it can be included in the diet replacing 25 per cent of the FMS fed to growing lambs for cost effective and eco-friendly production
