Reasons for Rex rabbit eating:

1、饲料搭配不合理。长期饲料单一，营养不全，粗饲料过多，或獭兔缺乏某些营养物质。

1. Unreasonable feed mix. Long term single feed, incomplete nutrition, too much roughage, or Rex Rabbits lack some nutrients.

2、饲料适口性差。獭兔喜食清淡或带甜味的植物性饲料，若饲料中混入有腥味或刺激性异味的饲料时，饲料适口性降低，獭兔易出现刨食现象。

2. Feed palatability is poor. Rex rabbits like to eat light or sweet plant feed. If the feed is mixed with fishy or pungent odor, the palatability of the feed will be reduced, and Rex rabbits are prone to gouging.

3、突然更换饲料。由于突然更换饲料，獭兔一时难以适应，往往拒食或刨食。

3. Suddenly change the feed. Due to the sudden change of feed, Rex rabbits are difficult to adapt and often refuse to eat or scrape.

4、拌料不均。在饲料加工时，若饲料搅拌不均匀，獭兔先挑适口性好的饲料吃，往往是边吃边刨。

4. Uneven mixing. In feed processing, if the feed is mixed unevenly, Rex Rabbits first choose the feed with good palatability, often planing while eating.

5、加料过多。喂料过多或食槽过小，易出现拱料、刨料现象。

5. Excessive feeding. If the feeding is too much or the trough is too small, it is easy to arch and planing.

7、刨食癖。有个别獭兔逐渐形成刨食恶癖，喂食后连吃带刨。

7. Planing mania. Some Rex Rabbits gradually formed a bad habit of planing and ate with planing after feeding.

预防对策：

Preventive measures:

1、采用大肚饲槽或卡脖饲槽可预防刨食。

1. The use of big belly trough or neck trough can prevent planing.

2、增加饲料适口性，配制饲料时，饲料原料混合均匀。

2. Increase the palatability of feed. When preparing feed, feed raw materials shall be mixed evenly.

3、少喂勤添。每次加料量不超过饲槽容量的1/3，以保持旺盛的食欲和饲料新鲜。

3. Don't feed qintian. Each feeding amount shall not exceed 1 / 3 of the feed tank capacity to maintain strong appetite and fresh feed.

4、对个别刨食严重或有刨食癖的獭兔，可采取饥饿控食1～2顿。

4. For individual Rex Rabbits with severe planing or planing addiction, starvation can be taken for 1 ~ 2 meals.
