摘要/Abstract

摘要： 紫色达利菊是自然生长在草原上的一种重要豆科牧草,与苜蓿具有相似的饲喂价值。高水分打捆有益于缩短牧草的田间养护期,降低损失风险,但因水分高、易发霉而不易贮藏,从而影响牧草的营养价值和安全性。本试验研究了丙酸对高水分紫色达利菊干草贮藏稳定性的影响。结果表明,高水分打捆(28%)与低水分打捆(17%)的紫色达利菊干草具有相似的化学组分,但高水分打捆不利于干草的贮藏。添加一定浓度的缓冲丙酸降低了(P<0.05)高水分打捆干草贮藏后期的温度、pH及中性洗涤纤维和酸性洗涤纤维的含量,减少了细菌总数及霉菌和酵母菌的数量,增加了干草粗蛋白和水溶性碳水化合物的含量。综上所述,添加丙酸有利于提高高水分紫色达利菊干草的营养价值、饲用安全性和贮藏稳定性。

Abstract: Purple prairie clover (PPC; Dalea purpurea) is an important legume that grows naturally on rangeland and has a feeding value similar to alfalfa. Baling hay with high moisture content is beneficial to shorten the field drying period and thereby reduce the risks of losses, but high-moisture hay is difficult to store as the high moisture content may result in degradation, loss of nutritive value, and sometimes toxic fungal growth in the stack. The effect of propionic acid on the stability of PPC hay bales with high moisture content was studied. The results indicated that PPC hay baled at high moisture content (28%) had similar chemical composition to those baled at low moisture content (17%). However, PPC hay baled at high moisture content was perishable and not easily stored. Inclusion of buffered propionic acid with at an appropriate rate in PPC hay bales baled at high moisture content was observed to significantly reduce the temperature in storage and forage pH, the neutral and acid detergent fibre levels, and numbers of bacteria, fungi and yeasts, especially after longer periods of storage (P<0.05), while at the same time increasing the crude protein and water soluble carbohydrate content of bales during storage. In summary, adding propionic acid to high moisture PPC hay bales, enhances their nutritional value, feeding safety and storage stability.
