The reason for the increase in economic benefits in the entire hog production process is that, in addition to good seed sources, feeding is also important. The following points are recommended for farmers' reference.
First, feed mash:
Corn, sorghum, barley, and other real feed, have a layer of hard skin. Therefore, crushing before feeding is very important. This can reduce the energy consumed when chewing, while increasing the contact area with the digestive juice, is conducive to digestion and absorption, improve feed utilization. The actual comminution of corn and other grains is generally good for medium fineness (particle diameter is 1-1.8 mm). The pigs are refreshing, eating a lot, gaining weight, and the feed utilization rate is also high. If the feed is finely crushed, it will cause damage to the pig's esophagus and gastric mucosa. It will also affect the pig's feed intake, reduce the rate of weight gain, and the feed utilization rate will be low. When barley and wheat are used to feed pigs, pressing into flakes is better than smashing.
Green feed, tuber, silage, and melon feed can be chopped or beaten and mixed in a mixed feed to reduce feed loss and energy consumption. When the amount of sugar beets is large, the crushing effect is best, and the finest powder is the best, otherwise it will cause indigestion of the pigs, causing diarrhea and causing intestinal diseases.
Second, feed feed method:
Due to the fact that the grain feed and its by-products such as bran, etc., will destroy a variety of vitamins after cooking, cause feed denaturation, greatly loss of nutrients. According to relevant experiments, the utilization of cooked feeds is at least 10% lower than raw feeds. Therefore, the grain feed and its by-products should be fed. Raw feed can not only effectively use nutrients in the feed, but also can save a lot of fuel and labor expenses. It is also one of the measures to increase economic efficiency in the pig breeding process. .
All kinds of green feed should be crushed or beaten. Cooking not only destroys vitamins, but it also causes nitrite poisoning when handled improperly. The cooked potato and its auxiliary materials can significantly improve the utilization of feed. Soybean and soybean meal cooked or fried better than raw.
Third, the amount of feed water:
The dry powder is directly fed to the pig without watering, saving time and labor. As long as the pigs are provided with sufficient drinking water, it is best to feed the pigs with dry powder. It is beneficial for pigs to ingest food, shorten the feeding time, reduce the dust caused by dry feed in the house, and cause the pigs to cough due to feed dust. It can also be fed with semi-dry powder or wet powder. The above feed can be fed in the feeding tank or on the concrete floor. Avoid feeding with soup in the feeding, which will reduce the secretion of various digestive juices, dilute the digestive juice, reduce the activity of various digestive enzymes, affect the digestion and absorption of feed, thereby reducing the weight gain rate and feed utilization. According to the test reasonable water ratio should be within 1:0.5-2, the best water content of 60-70%.
