【摘要】：本试验以伊犁昭苏马场的天然割草地及人工草地、外调苜蓿等青干草资源为原料,进行感官评价及营养成分分析,测定其品质,给予较全面的等级评价。结果表明,外调苜蓿和人工、天然割草地牧草高度分别为71.67 cm、67.00 cm、47.17 cm,相比之间有极显著差异(P0.01)。外调苜蓿和人工、天然割草地牧草的粗蛋白(CP)含量分别为13.63%、12.55%、7.75%,其中苜蓿的粗蛋白含量最高,各处理间有显著差异(P0.05)。不同青干草的中性洗涤纤维(NDF)、酸性洗涤纤维(ADF)和半纤维含量之间无显著差异(P0.05)。青干草资源品质的评价结果表明,外调苜蓿的品质最佳,评价结果为二级牧草,人工草地七月份进行刈割的青干草其品质的评价均属于2级牧草,八月份进行刈割的青干草属于三级牧草;天然割草地的青干草品质最低,属于四级牧草。
[Abstract]:In this experiment, the natural and artificial grassland of Zhaosu horse farm in Yili were used as raw materials for sensory evaluation and nutrient component analysis, and the quality was determined, and a more comprehensive grade evaluation was given to the green hay resources such as alfalfa. The results showed that there was a significant difference (P0.01) between alfalfa and artificial, natural cut grassland forage height of 71.67 cm,67.00 cm,47.17 cm,. The crude protein (CP) content of natural cut grass was 13.63 ~ 12.55 and 7.755.The crude protein content of alfalfa was the highest, and there was significant difference among the treatments (P0.05). There was no significant difference between neutral detergent fiber (NDF), acid detergent fiber (ADF) and semi-fiber content of different green hay (P0.05). The quality evaluation of green hay resources showed that the quality of alfalfa was the best, the evaluation result was the second grade forage, and the quality evaluation of green hay which was mowed on artificial grassland in July all belonged to grade 2 forage. The green hay mowed in August belongs to the third grade forage, and the natural cut grass has the lowest quality, belonging to the fourth grade forage.
