ThesisItem Open Access VISHWANATHA U(KVAFSU,BIDAR, 2019) VISHWANATHA UThe study was conducted to determine nutritional evaluation of maize top silage and maize top hay on dry matter intake, nutrient intake, digestibility, milk yield, milk composition and composition yield in lactating crossbred cows. Six lactating crossbred cows (Avg. b.wt; 358 ±27kg; milk yield 9.08±0.55 kg/day) were divided into two groups of three cows each in switch over design comprising two periods and allocated one of the following treatments; T1 - maize top silage (MTS) based diet, T2 - maize top hay (MTH) based diet. The experimental cows were offered an average 2 kg of paddy straw, MTS (5kg DM from silage of total DMI), adliditum of MTH, and CFM was offered to meet the requirement of nutrients (ICAR, 2013), in respective treatment. There was a significant difference in body weight change and body condition score between the groups. The total dry matter intake in T1 and T2 were 10.43 and 11.27, kg/d respectively and the ratio of roughage and CFM of the diet was 52:48 and 57:43 in corresponding groups. There was no significant difference in DMI but significantly higher intake of MTH than MTS. There was no significant difference in the nutrients intake and digestibility of nutrients, MN supply to the intestine and also in nitrogen balance, however all the cows were in positive nitrogen balance. The corrected lactometer reading (CRL) of the milk of experimental cows were 28.90 and 28.97 and 4 % FCM yield (kg/d) was 9.86 and 9.72 in T1 and T2 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 either maize top hay or maize top silage can be incorporated in the diet of lactating crossbred cows without affecting performance of the lactating cow. Key Words: Maize top silage, Maize top hay, Nutrient Intake, Milk Yield and its Composition.ThesisItem Open Access VIKAS D(KVAFSU,BIDAR, 2019) VIKAS DA in vitro and in vivo evaluation of areca sheath based total mixed ration initially by gas production technique followed by three month feeding, growth and metabolism trial in sheep to find voluntary feed intake, digestibility and growth performance in comparison to paddy straw. In vitro study revealed that ME and IVOMD of areca sheath and its dietary combinations were higher compare to paddy straw and its dietary combinations. ME (MJ/Kg) and IVOMD (%) of areca sheath were 7.82 and 55.81 respectively. Eighteen deccani lambs aged about 5 months (average body weight 16 kg) were randomly allotted to three total mixed ration formulated using paddy straw and areca sheath as roughage source and concentrate feed mixture. The experimental groups of lambs were receiving T1- diet comprised of paddy straw based TMR(50:50), T2 diet comprised of areca sheath and paddy straw based total mixed ration (25:25:50) andT3 diet comprised of areca sheath based TMR(50:50). The mean daily dry matter intake (g/kg W0.75) was significantly (P<0.01) higher in T1 (73.31) compare to T2(59.96) and T3(53.08).The digestibility of DM, OM, NFE, NDF, ADF was higher in T2 &T3 compare to T1 and no significant difference in the digestibility of CP,EE and CF among treatment groups. DCP (g/d) intake was significantly (P<0.01) higher in T1 (79.52) compare to T2 (56.93) and T3 (52.11). No significance difference in TDN intake among groups. ADG (g/d) were 93.33, 88.33, and 69.52 in T1, T2 and T3 respectively. It is observed that the areca sheath is comparable to paddy straw in chemical composition but having higher energy yielding potential through rumen fermentation and better digestibility of fibre. Nevertheless, areca sheath is having lower palatability as compared to paddy straw it could partially replace other regular crop residues, especially in total mixed rations, to produce cost effective balanced ruminant rations. The study opens up further scope to produce areca sheath based TMR in the form of pellets and fodder blocks to improve palatability and utilization.

Jackfruit waste (JFW), maize hay (MH), Concentrate feed mixture (CFM) and their various dietary combinations were studied by In vitro gas production technique. The RIVGP24 (ml/200mg DM), ME (MJ/kg),IVDOM (%), a (ml/200mg DM), D (ml/200mg DM), K (h-1), b (ml/200mg DM) and t1/2(h) value for JFW was 66.87, 11.32, 75.10, 5.36, 76.34, 0.08, 8.48 and 70.98 respectively. Among various dietary combination of JFW with CFM, JC50:50 dietary combination was showing significantly (P<0.01) higher RIVGP24 (71.71), ME (12.45), IVDOM (79.67), D (86.52), t1/2 (8.63). The ‘K’ value was significantly (P<0.01) higher for JC70:30 (0.13) and ‘b’ value for JC40:60 (86.83) combination. Similarly, significantly (P<0.01) higher values were obtained for RIVGP24, ME, IVDOM for JM90:10 (66.06, 11.21, 74.37) dietary combination. At dietary combination of JM30:70, significantly higher values were observed for ‘D’ (77.30) and ‘b’ (82.65). The ‘k’ and ‘t1/2’ values were significantly (P<0.01) higher in JM70:30 (0.11) and JM20:80 (8.54), respectively. A feeding trial of ten weeks duration was carried out on 14 sheep of 4-6 months old having an initial body weight of 13.8kg allotted to two groups of 7 animals of which control group (T1) of animals were fed with a basal diet of maize hay with supplemental CFM and for the treatment group (T2), 50 per cent of maize hay was replaced by JFW. The total DMI (g/d) was significantly (P<0.05) higher (678.99) in JFW (T2) as compared to control group (T1) of animals (577.40). There was a significantly (P<0.05) linear increase in the consumption of MH and JFW and total dry matter intake across the experimental period of 10 weeks. Significantly higher (P<0.01/0.05) OM, EE, NFE, NDF, ADF and HC intake was observed in T2 group as compared to control group of animals. The apparent digestibility of CF was unaffected by JFW supplementation. Whereas DM, OM, CP, EE, NFE and ADF digestibility were significantly (P<0.05) lower in test diet as compared to control diet. Further, NDF digestibility were significantly (P<0.05) higher in JFW fed animals (62.48%) as compared to control diet (54.12%).The DCP (<0.01), TDN, DOMD, ME and DCPI (<0.05) differ significantly higher at T1 as compared to T2. However, there was significantly (P<0.05) higher TDNI and MEI in T2 as compared to T1 groups. The average weekly body weight and average daily gain were comparable (P>0.05) among treatment groups. All the animals in the trial were in positive nitrogen balance. It was concluded that JFW could be used conveniently as a roughage source which partially or completely be replaced the traditional crop residue without affecting the growth and digestibility of nutrients in sheep.

N.; Dr. UMASHANKAR, B. C.A study was undertaken to evaluate the effect of extruded feeding finger millet straw based complete feed on the lactational performance of dairy cows. Six crossbred cows in late lactation were used in a switch over design study. Treatment diets were T1 group fed compounded feed mixture (CFM) and finger millet straw (FMS) as a roughage source offered separately and T2 group fed with finger millet straw based extruded complete feed (ECF). The total milk and 4 per cent FCM yield were significantly higher (P≤0.05) in T2 group (5.97, 6.66) compared to T1 group (5.32, 5.65). Considering the milk constituents (per cent), of T1 and T2 groups, the fat (4.37 and 4.71), SNF (9.02 and 9.23), protein (3.3ThesisItem Open Access NUTRITIONAL EVALUATION OF JACKFRUIT (ARTOCARPUS HETEROPHYLLUS) WASTE IN SHEEP(KARNATAKA VETERINARY, ANIMAL AND FOISHERIE'S SCIENCES UNIVERSITY, BIDAR, 2019-06) CHAITRA Y.; V.NAGABHUSHANAAn In vitro and In vivo evaluation of Jackfruit (Artocarpus heterophyllus) wastes was conducted to study the potential nutritional value and its feeding value in growing sheep.
