The research aimed to assess the nutritional value of ensiled (L. f.) Cass. (GA), also known as Noug or Niger, when treated with various additives, including urea, salt, molasses, and barley. The eight treatment groups were as follows: (I) GA forage without any supplementation (control), GA with supplement (II) 1% salt, (III) 2.5% molasses, (IV) 2.5% urea, (V) 5% barley, (VI) 2.5% molasses + 1% salt, (VII) 2.5% urea + 1% salt, (VIII) 5% barley + 1% salt supplement with GA. Silage samples were analyzed using physical, chemical, and microbiological methods to determine their nutritional composition, sensory characteristics, and microbial content. The objective of this analysis was to provide a comprehensive and objective evaluation of the silage samples. Based on the assessment of relative feed value (RFV) and relative forage quality (RFQ), it was determined that GA forage supplemented with 2.5% urea produced the highest-quality silage. The findings suggest that GA forage has the potential to serve as a high-quality silage. It is recommended that GA forage be ensiled with various additives at different inclusion rates. Further research is required to establish its digestibility and assess animal preference .
本研究旨在评估经青贮处理的(L. f.)野芥(GA)(又称诺格或尼日尔)在添加包括尿素、盐、糖蜜和大麦等各种添加剂后的营养价值。八个处理组如下:(I)不添加任何物质的GA草料(对照),添加了(II)1%盐、(III)2.5%糖蜜、(IV)2.5%尿素、(V)5%大麦、(VI)2.5%糖蜜 + 1%盐、(VII)2.5%尿素 + 1%盐、(VIII)5%大麦 + 1%盐的GA草料。使用物理、化学和微生物学方法对青贮饲料样本进行分析,以确定其营养成分、感官特性和微生物含量。该分析的目的是对青贮饲料样本进行全面客观的评估。基于相对饲料价值(RFV)和相对饲草质量(RFQ)的评估,确定添加2.5%尿素的GA草料制成的青贮饲料质量最高。研究结果表明,GA草料有潜力成为优质青贮饲料。建议以不同添加比例将GA草料与各种添加剂进行青贮。需要进一步研究以确定其消化率并评估动物偏好。
