    EFFECT OF FRESH BANANA PLANT WASTE AND ITS SILAGE ON DRY MATTER INTAKE, NUTRIENT DIGESTIBILITY AND RUMEN PARAMETERS IN OSMANABADI KIDS
    (KARNATAKA VETERINARY, ANIMAL AND FISHERIES SCIENCES UNIVERSITY, BIDAR- 585 401, 2015-01-01) SHIVARAM N. PATIL; T. THIRUMALESH
    Growth trial of twelve weeks duration comprised two phases of six weeks each was carried out on 15 kids (8-11 months; 16 kg body weight) which were divided into three groups of 5 kids each and were fed either control diet (T1), fresh banana plant waste (FBPW) plus CFM (T2), and fresh banana plant waste silage (FBPWS) plus CFM (T3) in Phase-I. In phase-II, for all the treatment groups red gram straw (RGS) was incorporated to meet the deficit DM requirement. The total DMI (g/d) in T1, T2 and T3 groups in phase-I and II were 504.9 and 533.9; 324.1and 558.1; 395.3 and 445.5, respectively which were significantly (P<0.01) different among the groups. Significant (P<0.01) difference was observed among treatment groups in CP, NDF and ADF intake. Similarly, no difference was observed in weight gain and also in nutrient digestibility in phase-I where as digestibility of DM, OM, CP and NFE were significantly (P<0.01) different in phase-II. The DCP and TDN values of the diet in both the phases were significantly (P<0.01) different. The rumen parameters like pH, TVFAs, NH3-N, TN, TCA-N and SN were estimated from the rumen fluid collected at the initial and final of the experiment were within normal range even though some difference was observed in few rumen parameters. It was concluded that FBPW and its silage supported for maintenance level of requirement, inclusion of RGS in the diet supported higher weight gain.

    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

    INFLUENCE OF DIFFERENT LEVELS OF NUTRIENTS ON PERFORMANCE OF LACTATING MALNAD GIDDA COWS
    (KARNATAKA VETERINARY, ANIMAL AND FOISHERIE'S SCIENCES UNIVERSITY, BIDAR, 2018-09) MANJUNATHA, H.T.; T. THIRUMALESH
    The study was conducted to determine the influence of different levels of nutrients on dry matter intake, nutrient intake, digestibility, milk yield, milk composition and composition yield in lactating Malnad Gidda (MG) cows. Six lactating MG cows (Avg. b.wt; 134 kg; milk yield 1.8 kg/day) were divided into three groups of two cows each in switch over design comprising three periods and allocated one of the following treatments; T1 fed 100 % of the requirement according to ICAR (2013), T2 was fed 10 % more than T1 and T3 was fed 20 % more than T1. The experimental cows were offered daily with 2.5 kg paddy straw, 3 kg hybrid napier and CFM was offered based on roughage intake to meet the requirement. There was a significant difference in body weight and condition change between the groups. The total DMI in all the groups were similar and the ratio of roughage and CFM of the diet was 52:48, 51:49 and 48:52 in T1, T2 and T3 groups, respectively. There was no significant difference in the nutrients intake and digestibility of nutrients, however all the cows were in positive nitrogen balance and per cent of N-retention was significantly (P<0.01) higher in T3 followed by T1 and T2 groups. The corrected lactometer reading of the milk of experimental cows ranged from 30.49 to 30.85 and 4 % FCM yield (kg/d) was 2.26, 2.27 and 2.44 in T1, T2 and T3 groups, respectively and difference was non-significant. There was no significant difference between groups in the component of the milk and composition yield. It was concluded from this study that Malnad Gidda cows were able to consume maximum dry matter 3.6 to 3.9 per cent of its body weight and feeding for optimum requirement is sufficient to improve body condition score, milk production and optimum milk composition rather than feeding at higher level of nutrients. Key Words: Malnad Gidda Cow, Nutrient Intake, Milk Yield and its Composition.

    (KARNATAKA VETERINARY, ANIMAL AND FISHERIES SCIENCES UNIVERSITY, BIDAR - 585 401, 2018-07) GIRIDHAR, K. S.; Dr. T. M. PRABHU
    Sesbania grandiflora, Melia dubia, Dillenia sp., Artocarpus heterophyllus, Commiphora caudata, Moringa oleifera, Leucaena leucocephala and Acacia auriculiformis leaves were selected for in vitro evaluation. The CP was more in Moringa oleifera. NDF and ADF higher in Dillenia and ADL in Acacia auriculiformis. CT was more in Artocarpus heterophyllus and saponin in Acacia auriculiformis. The Ca:P ratio was wider. ME was higher in Melia dubia lower in Dillenia sp. Addition of PEG improved the ME, D and k values. Effective and potential degradability of nutrients in Moringa oleifera, Melia dubia and Sesbania grandiflora were higher. The CP was positively correlated with ME, RIVIGP and in situ degradability. NDF, ADF, ADL, TP, TT and CT were negatively correlated with ME, RIVIGP, IVDMD and in situ degradability. In vivo feeding trial of 5 m duration was conducted using twenty four male lambs of were selected and divided into four groups comprising six in each group. T1 (control) fed with maize hay and CFM while in other three groups, 25% of maize hay was replaced with S. grandiflora (T2) or M. dubia (T3) or Dillenia sp.(T4) tree leaves. The proportion of CFM in T1 (48.25%) was significantly (P<0.05) higher. Tree leaves intake (g/d) for T2, T3 and T4 groups were 84.22, 87.89 and 76.77, respectively. DMI (g/d) for T1, T2, T3 and T4 groups were 693.4, 731.3, 749.6 and 736.4, respectively. ME intake and CP intake for T1, T2, T3 and T4 groups were 8.13 and 73.78; 8.28 and 81.9; 8.57 and 81.72; and 8.11 and 75.85, respectively. ADG (g) for T1, T2, T3 and T4 were 93.24, 103.80, 102.20 and 90.08, respectively. T2 gained significantly higher than T4 and it was non significant between T1 and T3. DOMDM (%) for T1, T2, T3 and T4 were 57.05, 58.61, 58.00 and 52.90, respectively and all the lambs were on positive nitrogen balance. Based on these results it was concluded that the tree leaves can be considered as supplementary source of nutrients for sustainable ruminant production in India.

    EFFECT OF ZINC SUPPLEMENTATION ON GROWTH PERFORMANCE OF LAMBS
    (KARNATAKA VETERINARY, ANIMAL AND FISHERIES SCIENCES UNIVERSITY, BIDAR, 2017-10) RAMACHANDRAIAH, M.; Dr. K. CHANDRAPAL SINGH
    A study was undertaken to evaluate the effect of dietary supplemental Zn on feed intake, digestibility of nutrients, growth performance and blood biochemical parameters in growing Mandya lambs. Eighteen lambs, aged 3-4 months with average body weight of 9.71 kg were divided into three groups of six each based on body weight. The experimental groups viz. T1, T2 and T3 received a basal diet comprising finger millet straw (Elucine coracana) and compounded feed mixture, fed in calculated quantities to a targeted body weight gain of 100 g per day. The Zn content in the diet of group T1 was 29.4 (control), while the groups T2 and T3 received additional supplementation of Zn (as ZnSO4) at 100 and 200 ppm respectively. The duration of the growth trial was 12 weeks. Dietary supplementation of Zn increased (P<0.05) the average daily weight gain of lambs (82.6, 103 and 102 g per day for T1, T2 and T3 groups respectively). Zinc supplementation also increased (P<0.05) the feed intake and apparent digestibility of DM, OM, NDF and ADF. The concentration of alkaline phosphatase and total serum proteins in groups T2 and T3 was higher (P<0.05) than the control groups. Feeding 200 ppm of Zn had no advantage compared to 100 ppm supplementation, in any of the parameters studied. It was concluded from the study that, as against the recommended levels of 30 ppm of Zn the diet of growing lambs, supplementation of 100 ppm could be more beneficial for achieving a higher growth performance in lambs.
