(1) Existing problems:

In actual production, some enterprises and farmers have no basis to follow when choosing chain, driving and auger feeding equipment, how should they choose? How does the automatic feeding system ensure uniform feeding? Will the feed stored in the tower deteriorate during the high temperature of summer? Can bulk trucks be equipped with metering equipment?

(2) Solution:

When choosing feeding equipment, it is necessary to comprehensively consider the feeding uniformity, dust generation, failure rate and accessory cost. For example, chain feeding equipment feeds evenly and produces less dust, but the failure rate and accessory cost are relatively high, and these indicators are trade-off.

Some people believe that the driving feeding equipment is economical, simple, uniform and suitable for China's national conditions; Chain feeding equipment is suitable for broiler breeding, dragon feeding equipment has good control over feeding speed, chicken stress and feed waste.

Some people believe that the noise of the driving feeding equipment is relatively small, the degree of feed fragmentation is low when used, and the dust is rarely generated after the cover plate is added.

It has been pointed out that tests have confirmed that the use of the auger feeding system can save 5-10 grams of feed per chicken, and the idling of the auger can also stimulate the feeding of the chickens.

It has been pointed out that in addition to restricting feeding, it is better to use chain feeding system for layer breeding, because the feeding amount is well controlled, and it is not limited by the length of the chicken house, which occupies less space and has a large aisle space in the chicken house.

In fact, some feeding systems are now equipped with automatic feeding devices, which can not only ensure uniform feeding, but also reduce the labor intensity of manual feeding, but the dialer will also cause blockage when encountering chicken feathers, which needs to be further improved.

It has been pointed out that some bulk trucks are now equipped with automatic metering devices, which can ensure the accuracy of batching. The feed storage time in the feed tower should not be too long, and the feed will not deteriorate in a short time (2-3 days).
