大熊猫膨化饼干饲料应用研究

对膨化饼干饲料饲喂大熊猫进行了研究，对日粮组合及饲喂方法作了重大改革。结果表明：使动物提高了日活动量，降低了排粘液次数有数量近一半，动物生长发育、营养状况、行为学及繁殖学各方面明显优于实验前，对提高动物健康与繁殖素质具有良好的作用。结果还表明动物对陌生环境和饲养因素的改变具有较强的适应能力，最长适应期为6个月，青年比老年个体适应性强。保持大熊猫的食竹特性十分重要。

Utilization of an Extruded High Fiber Biscuit Diet in Feeding Captive Giant Pandas (Ailuropoda melanoleuca)

A preliminary study on reformation of diet and dietary husbandry for two captive giant pandas (one adult male and one 5.5 year_old female) has been done at Zoological Society of San Diego during September 1996 to August 1997, which is based on a twelve_year long_term project of cooperative reproduction research for the giant panda with China. The panda pairs are fed with an extruded biscuit_shaped diet, which contains relatively high level of protein and fiber without milk and sugar matters, instead of their native diet of steamed grain bread plus milk, sugar, eggs and so on. The dietary is browsed animals by the way of more (than two) meals but a small amount and partially distributing the food in different parts of the animal's active area. Animals are also offered plenty of fresh bamboo daily, and water is freely available. Food consumption, body weight and fecal output of the animals are measured, and detail data on animal's development, health, behavior and reproductive feature are collected, too. The results have showed that both animals are quickly able to adapt them to the changes of husbandry factors, such as the environmental condition, food type and feeding schedule, and the maximum adaptive period might be six months. Well evidences have proved that both giant pandas are going normal, not only on their growth, development and nutrition, but also on the health, activities and routine behavior. A good quality and quantity of semen sample (3.36 ml, 90 % of motility, SOP=3) was collected from the male. Defecation of mucous stool of animals are greatly reduced in the interval, quantity and abdominal uncomfortment. Daily activities under feeding the biscuit increased double times more than it did before.
