在长毛兔的养殖上肯定会存在很多问题，在遇到问题的时候我们也需要慢慢的去解决。在长毛兔的体内存在着很多的元素，其中粗纤维是其中的一种，这种物质在体内也是起着关重要的作用。接下来小编就为大家来说一下粗纤维在长毛兔的营养功能以及长毛兔体内粗纤维的主要来源。

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.

粗纤维是构成植物性饲料细胞壁的基本物质，主要包括纤维素、半纤维素、木质素和果胶等，是植物细胞壁的主要成分，也是植物性饲料中难以消化的营养物质。长毛兔属单胃食草动物，其消化道结构能有效地利用植物性饲料，同时也产生了对植物纤维的生理需要。

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.粗纤维的营养功能

1. Nutritional Function of Crude Fiber

粗纤维在维持长毛兔正常消化机能、保持消化物稠度、形成硬粪及消化运转过程中起着重要的作用。成年兔饲喂高能量、高蛋白质日粮，往往事与愿违，不但不能加快生长，提高生产性能，反而会导致消化道疾病的发生。

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.

其主要原因就是粗纤维供给量过少，因而使肠道蠕动减慢，饲料通过消化道时间延长，造成结肠内压升高，从而引起消化紊乱，出现腹泻，甚死亡。但日粮中粗纤维含量过高，也会引起肠道蠕动过速，饲料通过消化道速度加快，营养浓度降低，饲料在消化道通过的时间过短，也会使部分营养浪费，导致营养不良，生产性能也会下降。

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.

粗纤维是植物细胞壁的主要组成成分，粗饲料中的各种干草、农作物秸秆和树叶类是长毛兔日粮中粗纤维的主要来源。据试验，长毛兔能够利用较多的粗饲料，能较好利用粗饲料中的粗纤维。

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.粗纤维的需要量

有关长毛兔日粮中的粗纤维水平，迄今见解不一。有的提出以12%~14%为宜；也有人提出饲喂16%~20%粗纤维含量的日粮，长毛兔生产性能较髙，发病率较低。据试验，长毛兔日粮中粗纤维水平与产毛性能有一定的关系。

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.
