In fact, corn and rice are both energy feeds, but when corn is fed to chickens, it needs to be processed into appropriate particle size, and the density of corn is low, which is easy for chickens to digest and absorb after eating, and the price is cheaper than rice. So corn is more suitable for raising chickens than rice.
Secondly, it is cost. Feeding corn greatly reduces the breeding cost and saves labor. Rice should be fed twice in the morning and evening, and corn once in the evening. So generally speaking, raising chickens or corn is better than rice.
Moreover, in terms of nutritional value, corn is the best choice to provide energy feed. Adding some green leaves or grass to corn flour is very suitable for raising chickens. However, the choice of chickens depends on the actual situation of their own farming.
In fact, from a certain point of view, the value of rice and corn is high or low, and what food to feed chickens can be adapted to local conditions. Rice can be used in the south because of its wide source and low cost. There are many people who grow corn in the north, so they can feed corn. However, the selection and selection of corn also need to be cautious.
Old corn can be fed directly, but new corn can't be fed directly. After the second ripening, you must wait for more than half a month to feed the chickens. This is because new corn contains resistant starch, which is not easily absorbed by chickens. Moreover, if the new corn is not properly fed, it may also lead to a decline in the egg laying rate, because the water content in the new corn is too high and the nutrient content is low, so it is not easy to be absorbed, and the natural egg laying rate will also decline.
