Reasons for Rex rabbit eating:

1、飼料搭配不合理。長期飼料單一，營養(yǎng)不全，粗飼料過多，或獺兔缺乏某些營養(yǎng)物質(zhì)。

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

2、飼料適口性差。獺兔喜食清淡或帶甜味的植物性飼料，若飼料中混入有腥味或刺激性異味的飼料時，飼料適口性降低，獺兔易出現(xiàn)刨食現(xiàn)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、突然更換飼料。由于突然更換飼料，獺兔一時難以適應(yīng)，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。在飼料加工時，若飼料攪拌不均勻，獺兔先挑適口性好的飼料吃，往往是邊吃邊刨。

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、加料過多。喂料過多或食槽過小，易出現(xiàn)拱料、刨料現(xiàn)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。有個別獺兔逐漸形成刨食惡癖，喂食后連吃帶刨。

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

預(yù)防對策：

Preventive measures:

1、采用大肚飼槽或卡脖飼槽可預(yù)防刨食。

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

2、增加飼料適口性，配制飼料時，飼料原料混合均勻。

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

3、少喂勤添。每次加料量不超過飼槽容量的1/3，以保持旺盛的食欲和飼料新鮮。

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、對個別刨食嚴(yán)重或有刨食癖的獺兔，可采取饑餓控食1～2頓。

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