当准备给长毛兔更换粮食时，这个看似简单的举动，实则是一场需要精心安排的 “过渡战役”。长毛兔的肠胃十分敏感脆弱，稍有不慎就可能因不适应新粮而出现软便、积食等不适症状。要实现换粮的 “软着陆”，避免肠胃 “抗议”，得掌握科学的方法和实用技巧。

　　When preparing to replace the food for the long haired rabbit, this seemingly simple action is actually a carefully planned "transitional battle". The gastrointestinal tract of long haired rabbits is very sensitive and fragile, and a slight mistake may cause discomfort such as soft stool and food accumulation due to not adapting to new food. To achieve a "soft landing" in food exchange and avoid gastrointestinal "protests", it is necessary to master scientific methods and practical skills.

　　换粮前的准备工作是打好基础的关键。要仔细观察长毛兔的身体状况，确保它处于健康状态再进行换粮。如果兔子正处于生病、怀孕、刚经历长途运输等特殊时期，肠胃功能本就较弱，此时换粮极易引发问题，应推迟换粮计划。同时，新粮的选择关重要，需根据长毛兔的年龄、体重、生理需求挑选合适的粮食，避免突然从低纤维粮换成高纤维粮，或更换成分差异过大的粮食。可以提前少量购入新粮，观察长毛兔对新粮气味、口感的初步反应，若兔子表现出抵触情绪，或许需要重新考虑新粮的选择。

　　The preparation work before grain exchange is the key to laying a solid foundation. Firstly, it is necessary to carefully observe the physical condition of the long haired rabbit to ensure that it is in a healthy state before changing the food. If the rabbit is in a special period of illness, pregnancy, or just experienced long-distance transportation, its gastrointestinal function is already weak, and changing food at this time can easily cause problems, so the food change plan should be postponed. At the same time, the selection of new grains is crucial, and suitable grains should be chosen according to the age, weight, and physiological needs of the long haired rabbits, to avoid suddenly switching from low fiber grains to high fiber grains or changing grains with significant differences in composition. You can purchase a small amount of new food in advance and observe the initial reaction of long haired rabbits to the smell and taste of the new food. If the rabbits show resistance, they may need to reconsider the choice of new food.

　　循序渐进的换粮方式是避免肠胃不适的核心策略。换粮过程通常需要 7 天左右，遵循 “逐步增加新粮比例，减少旧粮比例” 的原则。在换粮的第 1 - 2 天，新粮在混合粮中的占比控制在 20% 左右，剩下 80% 为旧粮。将新旧粮充分混合后投喂，让长毛兔开始接触并适应新粮的味道和口感。这个阶段，长毛兔可能会优先挑拣旧粮食用，这属于正常现象，无需过度干预。第 3 - 4 天，逐渐将新粮比例提升 40%，旧粮降 60%，继续观察长毛兔的采食和排便情况。若一切正常，在第 5 - 6 天，新粮比例可增加到 60%，旧粮为 40% 。到了第 7 天，基本可以完全过渡到新粮。整个过程就像为长毛兔的肠胃搭建一座平缓的 “桥梁”，让它慢慢适应新的食物成分和营养结构。

　　The gradual change of food is the core strategy to avoid gastrointestinal discomfort. The process of grain exchange usually takes about 7 days, following the principle of gradually increasing the proportion of new grain and reducing the proportion of old grain. On the first two days of grain exchange, the proportion of new grain in the mixed grain should be controlled at around 20%, and the remaining 80% should be old grain. Mix the old and new grains thoroughly and feed them, allowing the long haired rabbits to begin to come into contact with and adapt to the taste and texture of the new grains. At this stage, long haired rabbits may prioritize picking up old food for consumption, which is a normal phenomenon and does not require excessive intervention. On the 3rd to 4th day, gradually increase the proportion of new grain to 40% and decrease the proportion of old grain to 60%, and continue to observe the feeding and defecation of the long haired rabbits. If everything is normal, the proportion of new grain can increase to 60% and old grain to 40% on the 5th to 6th day. On the 7th day, it is basically possible to fully transition to new grains. The whole process is like building a smooth "bridge" for the digestive system of a long haired rabbit, allowing it to slowly adapt to new food ingredients and nutritional structures.

　　在换粮过渡期，日常的护理和观察必不可少。每天要定时定量投喂混合粮，保持规律的饮食节奏，避免因喂食不规律加重肠胃负担。同时，提供充足且干净的饮用水也非常重要，水分有助于促进消化，维持肠胃正常的蠕动功能。密切关注长毛兔的精神状态、采食情况和排便状况，这是判断其肠胃是否舒适的重要依据。如果发现长毛兔出现食欲不振、精神萎靡，或者粪便不成形、软便等异常情况，应立即减缓换粮速度。可以将新粮比例调回前一个阶段，观察 1 - 2 天，待兔子身体恢复正常后，再继续循序渐进地换粮。若异常情况持续或加重，需及时寻求人士的帮助。

　　During the transition period of food exchange, daily care and observation are essential. Regularly and quantitatively feed mixed grains every day, maintain a regular eating rhythm, and avoid increasing gastrointestinal burden due to irregular feeding. At the same time, providing sufficient and clean drinking water is also very important, as water helps promote digestion and maintain normal gastrointestinal motility. Pay close attention to the mental state, feeding habits, and bowel movements of long haired rabbits, which are important criteria for determining whether their digestive system is comfortable. If a long haired rabbit is found to have loss of appetite, mental lethargy, or abnormal conditions such as unformed feces and soft stools, the speed of changing food should be immediately slowed down. You can adjust the proportion of new grains back to the previous stage and observe for 1-2 days. After the rabbit's body returns to normal, continue to gradually change the grains. If the abnormal situation persists or worsens, seek professional help in a timely manner.

　　此外，换粮期间还可以适当添加一些有助于调理肠胃的辅助食物。比如，给长毛兔喂食少量的苜蓿草或提摩西草，这些草类富含膳食纤维，能促进肠胃蠕动，帮助消化。也可以在兽医的指导下，适量投喂益生菌，调节肠道菌群平衡，增强肠胃的适应能力和消化功能。但要注意，辅助食物的添加量不宜过多，以免影响正常的换粮进程和营养均衡。

　　In addition, during the food exchange period, some auxiliary foods that help regulate the gastrointestinal tract can be added appropriately. For example, feeding a small amount of alfalfa or Timothy grass to a long haired rabbit, which are rich in dietary fiber and can promote gastrointestinal peristalsis, helping digestion. Under the guidance of a veterinarian, probiotics can also be administered in moderation to regulate the balance of gut microbiota, enhance gastrointestinal adaptability and digestive function. However, it should be noted that the amount of auxiliary food added should not be too much, so as not to affect the normal process of food exchange and nutritional balance.
