Abstract

The present investigation was aimed at studying the improvement of fermentation and nutritive quality of rice straw-maize silage by the inclusion of different additives. In the experiment, paddy straw and green maize fodder were mixed in ratios of 100:0, 75:25, 50:50, 25:75, and 0:100 for silage preparation. These combinations were made in a triplicate and added with no additive (C), 2% urea (T1), 1% molasses (T2) and a mixture of 2% urea and 1% molasses (T3) in completely randomized design (CRD). The silages were harvested after 45 days and then analyzed for chemical composition, fermentation characteristics and anti-nutritional factors. Results revealed that dry matter (DM), acid detergent fibre (ADF), neutral detergent fibre (NDF), crude fibre (CF), ash and pH increased with an increase in the proportion of paddy straw in all combinations. Addition of 2% urea increased in vitro dry matter digestibility (IVDMD), crude protein (CP) and total gas production (TGP) of paddy straw and maize fodder silage. Urea treatment considerably reduced the oxalate content and increased the tannin content of paddy straw and maize fodder silage. In the present study, silage prepared by combining paddy straw and maize fodder in ratio of 25:75 had good aroma and fermentation characteristics which can be, therefore, utilized for effective silage making.

稻秆与糖蜜和尿素混合对玉米青贮发酵特性和营养价值的影响

本试验旨在研究添加不同添加剂对水稻秸秆-玉米青贮发酵和营养品质的改善作用。试验中，稻秆与绿玉米饲料按100:0、75:25、50:50、25:75、0:100的比例混合，进行青贮制备。采用完全随机设计(CRD)，将这些组合配制成3份，分别添加无添加剂(C)、2%尿素(T1)、1%糖蜜(T2)和2%尿素和1%糖蜜的混合物(T3)。45 d后收获青贮，分析其化学成分、发酵特性和抗营养因子。结果表明:各配比下，干物质(DM)、酸性洗涤纤维(ADF)、中性洗涤纤维(NDF)、粗纤维(CF)、灰分和pH均随稻秆添加比例的增加而增加。添加2%尿素可提高水稻秸秆和玉米饲料青贮的体外干物质消化率(IVDMD)、粗蛋白质(CP)和总产气量(TGP)。尿素处理显著降低了稻秆和玉米饲料青贮草酸含量，提高了单宁含量。在本研究中，稻秆与玉米饲料以25:75的比例配制青贮饲料具有良好的香气和发酵特性，可用于有效的青贮生产。

期刊介绍： Articles published in The Indian Journal of Animal Sciences encompass a broad range of research topics in animal health and production related to cattle, buffalo, sheep, goat, camel, equines, pig, rabbit, yak, mithun, poultry and fisheries. Studies involving wildlife species and laboratory animal species that address fundamental questions about their biology will also be considered for publication. All manuscripts must present some new development and must be original, timely, significant and scientifically excellent. Papers will be rejected if standards of care of, or procedures performed on animals are not up to those expected of humane veterinary scientists. At a minimum, standards must meet the International Guiding Principles for Biomedical Research involving Animals, as issued by the Council for International Organizations of Medical Sciences. (C.I.O.M.S., c/o WHO, CH 1211 Geneva 27, Switzerland). Articles reporting new animal disease must follow GOI directive as given in detail in Guidelines to Authors.
