Rabbits are mainly fed roughage. The so-called roughage, refers to the dry matter content of crude fiber is greater than or equal to 18%, the unit feed volume is large feed. Rabbit roughage mainly includes hay or straw. Among them, the common ones are dried green grass, dried vetch vine, soybean straw, corn stalk and so on.
How to choose these roughages? We can choose them according to the treatment method and nutritional value. As far as hay is concerned, artificial high-temperature drying has better nutritional value, but natural drying has lower cost if feed cost is considered; legume hay has better nutritional value than gramineous hay, so it should be given priority. It should be noted that the vitamin loss of artificial dried hay is large, and the lack of vitamin in feed should be considered when using, and the vitamin or special multidimensional should be added accordingly.
Among the chaff species, wheatgrass has rough and hard texture, high silicon content, blind thorns in leaves and low organic matter digestibility; barley grass has better texture than wheatgrass, spring barley grass has better texture than winter barley grass; oat grass has soft texture, slippery stalk and no blind thorns, which is better in straw; rice straw has higher lignin content and lower feeding value. In a word, this kind of feed has hard texture, high lignin content in crude fiber and low feeding value, while peanut vine and soybean stalk are better straw feed.
In roughage, it is better to feed rabbits with hay than with chaff. In general, hay can account for 20% - 30% of the formula feed, but the proportion of draft chaff feed should not exceed 20%. In addition, roughage should be crushed and mixed with concentrate (made into granules or mixed wet). Fine gramineous hay can be fed to rabbits. It should not be too fine when crushed. The fine powder is not conducive to the normal digestion and excretion of rabbits. The fineness is so that it can be mixed with other concentrate. Rabbits like to eat it. In particular, it is worth noting that Tong bran is widely used in rural areas. It is a kind of roughage with poor quality. Many farmers use it mixed with bran to feed rabbits. However, Tong bran is not suitable for weaning rabbits. Even for big rabbits and fattening rabbits, the dosage should not exceed 15%.
Due to the low content of energy and protein in green fodder and roughage, it can not meet the high-yield nutritional needs of rabbits, especially the improved breed rabbits. Feeding only green roughage will lead to the slow growth and development of rabbits, the decline of physical fitness, the decline of reproduction and lactation of female rabbits, the decline of meat production and so on. The so-called concentrate is a kind of feed with small volume, low crude fiber content, high energy or protein content, which is used to adjust the energy and protein level of rabbit feed to meet the needs of rabbit growth, reproduction, lactation and fattening. Wheat, grain, corn, beans and their by-products such as rice bran, wheat bran, oil cake, soybean residue are commonly used as concentrate feed for rabbits. Concentrate feed includes energy feed and protein feed.
Rabbit is a kind of single stomach herbivore, which can be fed with grass. Pure concentrate will lead to indigestion, diarrhea and other gastrointestinal diseases, even death. Therefore, the concentrate must be combined with the roughage to make a full price formula feed in order to feed rabbits. On the other hand, although concentrate has high nutritional value and good palatability, it is expensive. Therefore, in order to save cost, we should also choose concentrate and roughage as a reasonable mix.
