目前,对于饲料中营养物质和生物活性物质保存率与贮存期的关系问题,做过较为详细研究的还只限于草粉中的胡萝卜素。而饲料中蛋白质、特别是氨基酸的保存率情况则报导不多。本试验旨在研究几种最常见饲草中蛋白质和某些氨基酸的保存率与贮存期的关系。采集下列各种饲料样品:混合干草、青贮草、半干青贮、铡碎干草,干草饼,散草粉和草粉颗粒。于贮存前、贮存后2、4、6个月,检测蛋白质和氨基酸成份。
At present, for the relationship between the storage rate of nutrients and bioactive substances in feed and the storage period, more detailed studies have been done on the carotene in the meal. The feed protein, especially the amino acid preservation rate is not reported. The purpose of this experiment was to investigate the relationship between storage and preservation rates of several proteins and some amino acids in the most common forages. The following feed samples were collected: mixed hay, silage grass, semi-dry silage, ground hay, hay briquettes, pollen powder and grass powder granules. Pre-storage, storage 2, 4, 6 months after the test protein and amino acid composition.
