Application of roughage in pig farm
Roughage is the feed with higher crude fiber content. Herbivorous animal feed contains higher crude fiber, its raw materials with more than 30% of crude fiber corn straw, soybean straw, dry green special grass ground into powder as fiber feed source, they are added according to the proportion of the formula, the amount of crude fiber required in the formula is obtained by strict calculation. Corn fiber feed is made of corn stalk meal as crude fiber source. 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 do a detailed analysis of production, it is found that roughage has a special function, which is confirmed by the fact that rural free-range sows have a longer life span than farm sows. For this reason, we once again analyze the role of roughage:
1, roughage can provide nutrition: roughage provides little nutrition for piglets with weak digestion, but for sows with strong digestion ability, its nutritional effect is very obvious; 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 feed through the digestive tract time: this can effectively prevent sows constipation, especially late pregnancy; At the same time, digestion time is short, some harmful substances are not easy to accumulate in the intestinal tract, reducing the harm to pigs.
3, roughage can exercise pig's digestive function: long-term use of roughage, its digestive function is an exercise, so that sows have the ability to deal with all kinds of feed.
4, feeding roughage, pig feed intake must increase, thus its gastrointestinal volume is larger, is conducive to feeding more feed during lactation.
5, crude fiber price is low: especially farmers feeding, can make full use of cheap agricultural and sideline products, greatly reduce the cost of production.
Through the above analysis, the use of roughage in sows is more beneficial than harmful, even in intensive pig farms, even if the purchase of roughage, from the health perspective of sows, it is cost-effective.
Crude fiber has the following functions: although crude fiber can not provide nutrition to pigs, but also indispensable, one can play a satiating role, both conducive to excretion of feces, especially pregnant sows when the mother limit feeding, crude fiber is indispensable.
