Abstract

The paper compared the nutritional content and some physicochemical parameters of silages obtained with three forage crops, namely corn, corn-soybean mix and sorghum, and three frequent vegetable wastes, namely carrot, beet and potato. Dry matter (DM), pH, crude protein (CP), neutral detergent fiber (NDF), acid detergent fiber (ADF), and in vitro dry matter digestibility (IVDMD), lactic acid (LA) and butyric acid (BA) concentrations were examined in six silage types. DM, CP, NDF, ADF, IVDMD and LA contents differed significantly (P < 0.05) among the treatments. Corn silage had a greater DM percentage (32.66%) than ensiled vegetable residues. The highest concentration of CP was observed in fermented forage crops (8.70–9.50%). Silages made of vegetable residues showed significantly reduced ADF values (22.50–23.16%) as compared to ensiled forage crops (32.00–39.16%). The lowest NDF was observed in carrot silage (31.66%). Ensiled potato recorded the highest rate of in vitro digestion (86.33%). In the correlation analysis, it was observed that a highly positive correlation (P < 0.01) existed between DM and CP (r = 0.945), NDF (r = 0.943), and ADF (r = 0.851). Likewise, high positive correlations were evident between CP and NDF (r = 0.954) as well as ADF (r = 0.807). As compared to IVDMD, this was negatively and weakly correlated with ADF (r = 0.653, P < 0.01), DM (r = 0.617, P < 0.01) and NDF (r = 0.545, P < 0.05). Results show that vegetable-residue silages could be used as an alternative to ensiled forage crops.

以农业饲料作物和常见蔬菜废弃物为原料生产青贮饲料的特性和营养价值研究

比较了玉米、玉米-大豆混合料和高粱三种饲料作物和胡萝卜、甜菜和马铃薯三种常见蔬菜废弃物青贮的营养成分和一些理化参数。测定了6种青贮饲料的干物质（DM）、pH、粗蛋白质（CP）、中性洗涤纤维（NDF）、酸性洗涤纤维（ADF）以及体外干物质消化率（IVDMD）、乳酸（LA）和丁酸（BA）浓度。DM、CP、NDF、ADF、IVDMD、LA含量在各处理间差异显著（P < 0.05）。玉米青贮的干物质含量比青贮的蔬菜残粕高32.66%。发酵饲料作物中CP含量最高（8.70 ~ 9.50%）。青贮的ADF值（22.50 ~ 23.16%）显著低于青贮的饲料作物（32.00 ~ 39.16%）。胡萝卜青贮的NDF最低（31.66%）。青贮马铃薯的体外消化率最高（86.33%）。在相关分析中，DM与CP （r = 0.945）、NDF （r = 0.943）、ADF （r = 0.851）呈高度正相关（P < 0.01）。同样，CP与NDF （r = 0.954）和ADF （r = 0.807）呈高度正相关。与IVDMD相比，与ADF （r = 0.653, P < 0.01）、DM （r = 0.617, P < 0.01）、NDF （r = 0.545, P < 0.05）呈弱负相关。结果表明，蔬菜残料青贮可作为青贮饲料作物的替代饲料。

期刊介绍： Grassland Science is the official English language journal of the Japanese Society of Grassland Science. It publishes original research papers, review articles and short reports in all aspects of grassland science, with an aim of presenting and sharing knowledge, ideas and philosophies on better management and use of grasslands, forage crops and turf plants for both agricultural and non-agricultural purposes across the world. Contributions from anyone, non-members as well as members, are welcome in any of the following fields: grassland environment, landscape, ecology and systems analysis; pasture and lawn establishment, management and cultivation; grassland utilization, animal management, behavior, nutrition and production; forage conservation, processing, storage, utilization and nutritive value; physiology, morphology, pathology and entomology of plants; breeding and genetics; physicochemical property of soil, soil animals and microorganisms and plant nutrition; economics in grassland systems.
