    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.

    EVALUATION OF SELECTED TREE LEAVES AS RUMINANT FEEDSTUFF BY IN VITRO AND IN VIVO METHODS
    (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.

    EFFECT OF SUPPLEMENTATION OF LYSINE PRODUCING MICROBES VIS-A-VIS TYPE AND LEVEL OF DIETARY PROTEIN, ON PERFORMANCE OF POST PEAK LAYERS
    (KARNATAKA VETERINARY, ANIMAL AND FISHERIES SCIENCES UNIVERSITY, BIDAR 585 401., 2005-12-30) MANJU, G. U.; B. S. VENKATARAMI REDDY; R. GIDEON GLORI DOSS; . T. M. PRABHU; K.S. PRATHAP KUMAR
    Poultry farming in India was a backyard practice till 1970 and now it has made rapid strides and transformed itself to become increasingly specialized and integrated agribusiness to meet the increasing demand for human food production and contributing its part to National GDP. At present, India stands 4^^ among the world’s egg producing countries, with an increase from meager 1800 million eggs during 1960 to 40,000 million in 2004 (FAO 2004). Such a commendable achievement was possible largely due to concerted efforts of several poultry entrepreneurs, including geneticists and nutritionists. Chicken is one of the best , feed converting livestock among the food animals and also low space requirement involved in their production have significantly contributed towards the phenomenal growth of the poultry sector. But stiU there is a wide gap between recommendation (180 per annum ICMR) and the present per capita consumption level of eggs (48 eggs per annum) with an eventual provision of tremendous scope for growth of poultry industry especially that of layers.

    Influence of Lysine Producing Probiotics (LPP) vis-a-vis type of protein source on performance of broilers
    (KARNATAKA VETERINARY, ANIMAL AND FISHERIES SCIENCES UNIVERSITY, BIDAR, 2005-12-30) JAISHANKAR, N; B. S. VENKATARAMI REDDY; R. G. GLORI DOSS; T. M. PRABHU
    Over the last few decades, broiler production in tropical and subtropical countries has been rapidly increasing due to ever increasing demand for poultry products. From 1995 to 1999, chicken meat production in Africa, Asia and South America grew by 13.85, 17.73 and 23.65%, respectively (Watt, 2001). Despite many challenges faced by broiler industries in these developing nations, including economic crisis, currency devaluation and reliance on imported raw materials, it is predicted that broiler production in these areas will continue to sustain strong growth in the future as well. As a result, the feeding and health management of birds assume significance. Soon after the introduction of antimicrobials into human chemotherapy in the 1940s, they were also introduced into veterinary practice (Moore et al., 1946). Consequently, Chickens became more susceptible to colonization by bacterial pathogens. When livestock and poultry are fed low doses of antibiotics routinely, bacteria may develop resistance to the drugs (Collignon, 1999). Certain scientific findings (Manning et al., 1994) suggested that antibacterials used for animal feeding become risky for humans (Sahin, 2002) and animal health (Thorns, 2000) and the conclusions of scientific committee of the European Council have thus led to a ban on feeding antibiotics (Witte, 2000). Nevertheless, increased public concern over the development and spread of antibiotic resistance in bacteria and the possible presence of antibiotic residuals in poultry products has led to search for safe alternatives to antibiotics in chicken diets (Gong et al., 2002). Currently, many parts of the world are experimenting alternative feed additives that may be used to alleviate the problems associated with the withdrawal of antibiotics from feed. The supplemental dietary microbial products function in the digestive system 1) to provide nutrients, 2) to aid in digesting foods and 3) to inhibit harmful bacteria (Owings et al., 1990). In this direction certain probiotics have been discovered to facilitate or
