概括

麻粉是一种安全高品质的蛋白质补充剂,用于非哺乳乳奶牛,对营养状况或组织中大麻素的存在没有不良影响. 大多数摄入的大麻素都在便中分泌出来.

科学领域:

动物科学动物科学
营养科学营养科学
农业科学农业科学

背景情况:

麻粉 (HM) 是乳牛的潜在蛋白质补充剂.
它作为料的质量和安全性,包括大麻素的存在,需要进行彻底的调查.

研究的目的:

评估HM补充剂对奶牛DMI,小发酵,血液代谢物和全道消化能力的影响.
通过分析血,尿液和组织中的大麻素度来确定HM的安全性.

主要方法:

六只不哺乳的荷尔斯坦奶牛被养为HM,甘露粉 (CM) 或混合 (HC) 的饮食,以3x3拉丁方形设计.
评估干燥物质摄入量 (DMI),乳头参数,血液代谢产物,营养消化能力和大麻素水平.

主要成果:

补充HM并没有影响DMI,乳头发酵或大多数血液代谢物,这表明对营养状况没有负面影响.
与CM相比,HM的总通道中性洗剂纤维消化率较低.
没有在血,尿液或组织中检测到大麻素 (CBD,CBDA,THC,THCA);大多数被排泄在便中.

结论:

麻粉是一种高质量和安全的蛋白质补充剂,用于非哺乳乳母牛,含量高达10.2%的DM.
来自HM的食大麻素在很大程度上没有被吸收和分泌,对动物没有危险.

关键词:

Proteins: Dietary Sources and Requirements

Consuming animal-based products offers high-quality proteins that contain optimal levels and combinations of essential amino acids, crucial for tissue repair and growth. Foods like eggs, milk, fish, and most meats are a source of complete proteins. Legumes and cereals are abundant in proteins; however, they typically lack a full range of essential amino acids. As a result, they are considered incomplete protein sources. Some plant sources like soybeans, quinoa, and amaranth do contain complete...
