Application of roughage in pig farm


Roughage is a kind of feed with higher crude fiber content.
Herbivorous animal feeds contain high crude fiber, and their raw materials are mostly made of corn stalks, soybean stalks and dry green special grass which contain more than 30% crude fiber and are added according to the proportion of the formula, and the amount of crude fiber needed in the formula is calculated strictly.
Corn fiber feed is composed of corn stalk meal as crude fiber source and added into feed.
The crude fiber content of feed can be determined by using ST116 crude fiber tester (produced by Shandong Shengtai Instrument Co., Ltd.)
Many people would think that roughage is a worthless ingredient for pigs, but if we conduct a detailed analysis of production and find that roughage has a special effect, this can be confirmed by the fact that rural free-range sows have a longer life than pig sows, for which we again analyze the effect of roughage:
1, roughage can provide nutrition: roughage can provide very little nutrition for piglets with weak digestion, but for sows with strong digestion, its nutritional effect is significant;
First sows microbial crude fiber can be broken down into time inside large intestine absorption use volatile fatty acids, the second microbes can use roughage in difficult to digest crude protein into easy digestion and absorption of thalli proteins, the third microbes can also synthesis of water-soluble vitamins, and a variety of vitamins is generally lacking in feed.
2, roughage can shorten the time of feed through the digestive tract: this can effectively prevent constipation of sows, especially in the late pregnancy;
At the same time, the digestion time is short, some harmful substances are not easy to accumulate in the intestinal tract, reducing the damage to pigs.
3, roughage can exercise the digestive function of pigs: long-term use of roughage is a exercise for its digestive function, so that sows have the ability to deal with various feeds.
4. When fed roughage, the feed intake of pigs will increase, so that their gastrointestinal volume will be larger, which is conducive to eating more feed during lactation.
5, low price of crude fiber: especially farmers feeding, can make full use of cheap agricultural and sideline products, greatly reduce production costs.
Through the above analysis, the advantages of the use of roughage on sows still outweigh the disadvantages. Even if it is an intensive pig farm, even if it is to spend money on roughage, it is cost-effective from the point of view of sow health.
Crude fiber has the following functions: Although crude fiber does not provide nutrition to pigs, it is indispensable. Crude fiber can play the role of satiety, and both are conducive to fecal discharge, especially in pregnant sows when mothers are restricted to feed. Crude fiber is indispensable.
