ArticleItem Open Access Assessment on the incidence of aflatoxin B1 in composite cattle feed and raw materials in India(TANUVAS, Chennai, 2020-01) Murugeswari, R.; TANUVASComposite cattle feed samples and raw materials like maize, wheat, sorghum, broken rice, pearl millet, groundnut cake, cotton seed cake, mustard cake, soyabean meal, rapeseed meal, sunflower meal, guar meal, safflower meal, deoiled rice bran and wheat bran were collected from various parts of India for a period 5 years and evaluated for aflatoxin B1 level by screening through ELISA and confirmation through HPLC. Among the 482 composite cattle feed samples, only 68.5per cent were having aflatoxin B1level below the permissible level (below 20 ppb). Higher incidence of aflatoxin B1 was recorded in west zone than east, north and south zones during monsoon period. However, it was observed that incidence of aflatoxin B1 at concentration beyond 100ppb was relatively higher in eastern zone both during monsoon and non-monsoon period than the west, north and south zones. Among the energy source, maize had the highest (7.8 per cent, 15 out of 193 samples tested) prevalence of alarming levels of aflatoxin (>100ppb) and 41.5 per cent (80 samples) in the range of 21 to 100 ppb of aflatoxin B1. Only 50.8 per cent (98 samples) were within permissible level (<20 ppb). It was observed that the presence of aflatoxin B1was more in maize during monsoon in south zone. Only 47.2 per cent of groundnut cake (118 samples) were within permissible level of <20 ppb of aflatoxin B1. In west zone, highest sample profile (15.18per cent) and zone-wise distribution of 45.45per cent was recorded in the samples of groundnut cake having aflatoxin B1 at alarmingly high level of more than 100 ppb. Overall data reveals that monsoon favours development of aflatoxin B1 more during monsoon.OtherItem Open Access Chemical Composition and In-vitro Nutrient Degradability of Hydroponically Grown Fodder Maize(TANUVAS, 2013-08) Bandeswaran, C.; Gunasekaran, S.; Murugeswari, R.; Viswanathan, K.ArticleItem Open Access Effect Of Extrusion Of Swine Grower Feed On Nutrient Digestibility And Production Performance In Large White Yorkshire Pigs(TANUVAS, Chennai, 2021-07) Murugeswari, R.; Murugan, M.; Bandeswaran, C.; Valli, C.; TANUVASA study was conducted to determine the effect of extrusion of swine grower feed on the nutrient digestibility and production performance in twentyfour conventionally weaned LWY piglets 30 days of age and 7.60 kg average body weight. They were grouped in to two groups with twelve piglets in each group and fed individually with mash feed (MF) and extruded feed (EF) ad libitum.The experiment was conducted for 90 days. The feed was formulated with maize (62.5%), soybean meal (10%), fish meal (6%), wheat bran (8%), deoiled rice bran (11%), mineral mixture (2%) and salt (1%). The extrudate was air-dried overnight and analysed for its chemical composition.The results indicated that the moisture (MF- 9.54% and EF - 5.17%), total ash -TA (MF- 7.77% and EF - 6.35%), crude protein-CP (MF- 18.14% and EF - 17.36%), ether extract -EE (MF- 2.04% and EF - 1.74%), crude fibre– CF (MF- 6.13% and EF - 5.04%), nitrogen free extract – NFE (MF- 65.05% and EF - 69.51%), calcium (MF- 0.07% and EF - 0.06%), phosphorus (MF- 0.44% and EF - 0.45%) and gross energy– GE (MF- 3870.55 kcal/kg and EF - 4105.75 kcal/kg). The extrusion process decreased moisture, TA, EE and CF significantly (P<0.05) and also increased NFE and GE significantly (P< 0.01) in the extruded feed.The digestibility of dry matter (MF- 84.19% and EF -87.28%), CP (MF- 91.29% and EF -93.21%), EE (MF- 69.21% and EF - 1.74%), CF (MF- 81.44% and EF -87.54%) and energy (MF- 77.94% and EF -83.36%) were recorded.The digestible nutrients of EE and CF were increased significantly (P<0.05) and energy of (MF – 77.94%) extruded feed was increased significantly (P<0.01) by 7 per cent than the mash feed (EF- 83.36%).The average feed intake was significantly (P<0.05) different from MF (2417.43g/day) to EF (2106.97g/day) group.OtherItem Open Access Effect of Harvesting Method of Paddy (Oryza Sativa) Straw on its Quantity and Quality(TANUVAS, Chennai, 2013-06) Murugeswari, R.; Viswanathan, K.; Babu, M.ArticleItem Open Access The Effect of TANUVAS Grand Supplement in Augmenting Milk Production and Preventing Metabolic Disorder in Cattle(TANUVAS, 2013-08) Balakrishnan, V.; Murugeswari, R.; TANUVASOtherItem Open Access Effect of TANUVAS Grand® on Milk Production(TANUVAS, 2013-08) Balakrishnan, V.; Murugeswari, R.ArticleItem Open Access Evaluation of Cumbu Napier Hybrids Co(CN)4 And Co(BN)5 in Crossbred Cattle(TANUVAS, Chennai, 2021-07) Mynavathi, V.S.; Murugeswari, R.; Valli, C.; TANUVASGreen fodder feeding is most important for milking cows. An experiment was carried out to compare the growth, performance, proximate composition and nutritive value of Bajra Napier hybrid Co(BN)5 (improved variety) with the standard variety Co(CN)4.Both the cultivars were cultivated in irrigated land comprising red sandy loam soil by following standard agronomical practices and 0.5 acre of land area was utilized for each cultivar. Fodder was harvested on 75th day after planting and subsequent harvest at every 45 days in each experimental plot. The growth and yield parameters were measured.The yield was significantly (p<0.01) higher in Co(BN)5 (360.50t/ha/year)followed by Co(CN)4(290.12t/ ha/year).The biometric observations showed the significant (p<0.05) difference in Co(BN)5 than Co(CN)4. The samples were collected for analyzing chemical composition.The results indicated that the crude protein, crude fibre, NDF, ADF and cellulose content of Co(BN)5 were significantly (p<0.01) higher than Co(CN)4. The fodder crop cultivars were analysed for IVDMD.The IVDMD of Co(BN)5 (49.18%) was significantly higher than the Co(CN)4 (43.09%). A Lactation trial was conducted in twelve cross bred cows during mid lactation period and separated into two groups with six animals in each group. One group was named as control (C) and fed with Co(CN)4 green fodder and another group named as treatment (T) and fed with Co(BN)5. The animals were housed in standard condition, dewormed and fed with clean potable drinking water ad libitum.The experiment was conducted for 90 days. Except green fodder variation, animals were offered ad libitum paddy straw and concentrate mixture according to their level of production. The feed and fodder intake, left over and dry matter intake were recorded every day. The average dry matter intake was recorded and inferred that it was significantly (P<0.05) different. The average milk yield, milk fat, solid non-fat and total solids were recorded for both groups. The average milk yield in treatment group is highly significant (p<0.01) than control group. There was no change observed in the milk fat and solid non-fat. The feed cost was calculated for every litre of milk production.The feed cost is significantly (p<0.01) reduced in treatment group due to the less requirement of Co(BN)5 fodder when compared to Co(CN)4 fodder. It is concluded that Cultivar Co(BN)5 is superior than Co(CN)4 in terms of crop growth and biomass yield. Hence, cultivation of Bajra Napier Cultivar Co(BN)5 and feeding the same to improve the milk yield in cattle is the outcome of this study.OtherItem Open Access Leguminous Fodder Feeding to Ruminants as Hay Block(TANUVAS, 2013-08) Murugeswari, R.; Bandeswaran, C.; Gunasekaran, S.OtherItem Open Access Mixed Hay Block - A Drought Feed for Ruminants(TANUVAS, 2013-08) Mynavathi, V.S.; Murugeswari, R.; Gopi, H.; Bandeswaran, C.; Murugan, M.ArticleItem Open Access Prevalence and magnitude of acidosis sequelae to rice-based feeding regimen followed in Tamil Nadu, India(2018-04) Murugeswari, R.; Valli, C.; Karunakaran, R.; Leela, V.; Pandian, A.
