基于模糊相似优先比法评价规模化牧场全株玉米青贮饲料品质

【目的】研究新疆北疆地区规模化牧场全株玉米青贮饲料品质及生产水平，分析全株玉米青贮饲料品质，为推动新疆北疆地区青贮饲料高效生产提供依据。【方法】采集新疆北疆地区18个不同规模牧场中窖贮全株玉米青贮饲料，分析营养品质、发酵品质、霉菌毒素含量，运用模糊相似优先比法综合价值评定各规模化牧场全株玉米青贮饲料品质。【结果】各牧场青贮营养品质及发酵品质整体水平达到国家二级标准，所有牧场的霉菌毒素含量均符合国家限量标准。排名前三位的牧场为R>I>Q(存栏量在1 000头以上的牧场),排名后三位的牧场为N>L>H(存栏量在500头以下的牧场)。【结论】新疆北疆地区规模化牧场全株玉米青贮品质整体水平良好，但不同规模牧场之间存在差距，存栏量在1 000头以上的牧场整体水平优于存栏量在500头以下的牧场；各牧场全株玉米青贮品质主要受青贮玉米品种、地区气候特性、牧场规模的影响。

Evaluation of the Whole-Plant Corn Silage Quality of Large-Scale Pastures Based on Fuzzy Similarity Priority Ratio Method

【Objective】 The purpose of this study is to determine the quality and production level of whole-corn silage in large-scale pasture in northern Xinjiang and analyze the problems in the production of whole-plant corn silage in the hope of providing basis for promoting efficient production in the region. 【Method】 Whole-plant corn silage in 18 pastures of different scales were collected and nutritional quality, fermentation quality, and mycotoxin content analyzed by using the fuzzy similarity priority ratio method to comprehensively evaluate the whole-plant corn silage in each pasture. 【Result】 The overall level of nutrient quality and fermentation quality of each pasture silage reached the national second-level standard, the mycotoxin content of all pastures conformed to the national limit standard.The comprehensive evaluation showed that the top three pastures were: R > I > Q (pastures with a stock of more than 1,000 heads), the bottom three pastures were: N > L > H (pastures with a stock of less than 500 heads). 【Conclusion】 In summary, the overall quality of whole-plant corn silage in large-scale pastures in northern Xinjiang is excellent, but there is a gap between different scales of pastures.Pastures with inventory of more than 1,000 heads are better than pastures with inventory of less than 500 heads; the quality of whole-plant corn silage in each pasture was mainly affected by silage corn varieties, regional climate characteristics and pasture scale.
