Crushing and crushing of various cereal feeds such as barley, corn, sorghum, etc., must be crushed or flattened before feeding, especially for hard-shelled cereals, this processing is more important. Because these hard-shelled grains are generally not digested in the digestive tract of livestock, many grains will be excreted with the feces, causing waste. If crushed or flattened, not only livestock can be easily chewed, but also the contact area between nutrients in the feed and the digestive juice is increased, the digestibility is improved, and it is also easy to mix with other feeds. The degree of comminution of the feed should be determined according to the type of livestock: cattle and sheep's feed can be broken into 2 millimeters; feed for horses, donkeys and quail can be broken into 4 millimeters.
Immersion immersion modulation method, generally applies to oil cake concentrate feed. The soaked feed is easy to chew and digest, especially for pigs and poultry. The water that soaks the feed contains various nutrients and should be fed together with the ingredients. Soaking the oil cake feed in the summer is prone to spoilage, and the time should not be too long.
Boil steaming and roasted and roasted are two kinds of preparation methods suitable for bean feed. After cooking and frying, the utilization of protein and starch increased. In addition, broiling can make the feed produce a fragrance odor, improve palatability, increase the appetite of livestock and increase feed intake.
Saccharification This method is suitable for feeds containing starch, which contains starch can be fully converted to dextrin and maltose, the content can be increased from 1% to 10%. The saccharified feed has a sweet taste and livestock are very fond of eating.
Fermented concentrate fermentation is one of the most commonly used methods for culturing pigs and cows. After fermentation, feed can improve palatability, increase digestibility and utilization of crude protein, and increase vitamin B content. After fermentation, the concentrate feed has a good effect on the appetite, health, reproduction and feed utilization of livestock.
