在長毛兔的養殖上肯定會存在很多問題，在遇到問題的時候我們也需要慢慢的去解決。在長毛兔的體內存在著很多的元素，其中粗纖維是其中的一種，這種物質在體內也是起著關重要的作用。接下來小編就為大家來說一下粗纖維在長毛兔的營養功能以及長毛兔體內粗纖維的主要來源。

There will be many problems in the breeding of rabbits, and we need to solve them slowly when we encounter problems. There are many elements in the body of rabbits, of which crude fibers are one of them. This substance also plays a vital role in the body. Next, we will talk about the nutritional function of crude fibers in rabbits and the main source of crude fibers in rabbits.

粗纖維是構成植物性飼料細胞壁的基本物質，主要包括纖維素、半纖維素、木質素和果膠等，是植物細胞壁的主要成分，也是植物性飼料中難以消化的營養物質。長毛兔屬單胃食草動物，其消化道結構能有效地利用植物性飼料，同時也產生了對植物纖維的生理需要。

Crude fiber is the basic substance that constitutes the cell wall of plant feed. It mainly includes cellulose, hemicellulose, lignin and pectin. It is the main component of plant cell wall, and is also the nutrient that is difficult to digest in plant feed. Long-haired rabbit is a single-stomach herbivore. Its digestive tract structure can effectively utilize plant feed, but also has a physiological need for plant fiber.

1.粗纖維的營養功能

1. Nutritional Function of Crude Fiber

粗纖維在維持長毛兔正常消化機能、保持消化物稠度、形成硬糞及消化運轉過程中起著重要的作用。成年兔飼喂高能量、高蛋白質日糧，往往事與愿違，不但不能加快生長，提高生產性能，反而會導致消化道疾病的發生。

Crude fibers play an important role in maintaining the normal digestive function, maintaining the digestive consistency, forming dung and digestive operation of long-haired rabbits. Adult rabbits fed high-energy, high-protein diets often go against their wishes, not only can not accelerate growth and improve production performance, but also can lead to digestive tract diseases.

其主要原因就是粗纖維供給量過少，因而使腸道蠕動減慢，飼料通過消化道時間延長，造成結腸內壓升高，從而引起消化紊亂，出現腹瀉，甚死亡。但日糧中粗纖維含量過高，也會引起腸道蠕動過速，飼料通過消化道速度加快，營養濃度降低，飼料在消化道通過的時間過短，也會使部分營養浪費，導致營養不良，生產性能也會下降。

The main reason is that the supply of crude fibre is too little, which slows down the intestinal peristalsis, prolongs the time of feeding through the digestive tract, and causes the increase of the internal pressure of the colon, resulting in digestive disorders, diarrhea and even death. However, the high content of crude fibre in the diet can also cause intestinal peristalsis. The speed of feed passing through the digestive tract is accelerated, the nutrient concentration is reduced, and the passage time of feed in the digestive tract is too short, which will also waste part of the nutrition, lead to malnutrition and reduce the production performance.

2.粗纖維的主要來源

2. Main sources of crude fibers

粗纖維是植物細胞壁的主要組成成分，粗飼料中的各種干草、農作物秸稈和樹葉類是長毛兔日糧中粗纖維的主要來源。據試驗，長毛兔能夠利用較多的粗飼料，能較好利用粗飼料中的粗纖維。

Crude fiber is the main component of plant cell wall. Various kinds of hay, crop straw and leaves in coarse feed are the main sources of crude fiber in rabbit diet. According to the experiment, the rabbit can utilize more roughage and better utilize the crude fibers in the roughage.

3.粗纖維的需要量

3. Crude Fiber Requirements

有關長毛兔日糧中的粗纖維水平，迄今見解不一。有的提出以12%~14%為宜；也有人提出飼喂16%~20%粗纖維含量的日糧，長毛兔生產性能較髙，發病率較低。據試驗，長毛兔日糧中粗纖維水平與產毛性能有一定的關系。

There are different opinions on the crude fibre level in the diet of long-haired rabbits. Some suggested that 12%~14% should be the best diet, while others suggested that 16%~20% crude fibre content should be fed. The growth performance of long-haired rabbits was better than that of goats, and the incidence of disease was lower. According to the experiment, the level of crude fibre in the diet of long-haired rabbits has a certain relationship with wool production performance.
