Compound feed for broiler chicken in later period

Abstract

The invention belongs to the technical field of poultry feeds, and particularly relates to a later-stage compound feed for broiler chickens. The earthworm powder, the river snail powder, the tenebrio molitor powder and the silkworm chrysalis powder are newly added, so that the feed protein is sufficient in amount and complete in variety. The invention further provides a rotary rolling type drying machine required for later-stage compound feed production of broiler chickens, the rotary rolling type drying machine structurally comprises a bottom plate, a mounting plate unit for clamping, a rotary heating pipe unit, a rolling material pipe unit, a driving motor unit for rolling and a sliding rod unit, and the rotary rolling type drying machine has the advantages of being more flexible, efficient and rapid in heating operation.

Description

technical field [0001] The invention belongs to the technical field of poultry feed, in particular to a late-stage compound feed for broiler chickens. Background technique [0002] Broiler chicken is generally used for roasting or frying. It has many advantages such as plump muscles, tender meat, smooth skin, low fat content, soft breastbone and easy to cook. The slaughter time of broiler chicks is generally 6-8 weeks, and the slaughter weight is generally 1.5-2.0kg. The most prominent advantage during growth is the high feed utilization rate, and the feed-to-meat ratio can reach 2:1. [0003] On the other hand, a total growth cycle of about 50 days can generally be divided into the early stage of the first 20 days, the middle stage of the middle 20 days, and the late stage of the last 10 days. Each of the three stages has its own corresponding special compound feed. [0004] For example, the Chinese invention patent with the patent publication number CN103875924A and the p...

Problems solved by technology

[0008] 1. The moisture content is too high, and most of the workload of the pulverizer is used to "cut water", which increases power consumption and prolongs the pulverization time;

[0009] 2. The final obtained powder is also a wet material. If it is not used to produce broiler feed immediately, the wet material will soon rot and become essential;

[0010] 3. All kinds of harmful bacteria, insect eggs, viruses, etc. carried by the raw materials directly enter the feed system. Although the subsequent high-temperature puffing operation can also sterilize bacteria and viruses, it will eventually increase the degree of harm and time of the above-mentioned harmful substances.

[0012] However, the drying system in this utility model patent has the biggest problem when drying and heating the above-mentioned animal raw materials: the heating time is uncontrolled, and it is too short, and it is inconvenient to reheat when it falls. The overall heating operation not enough
