Description

Technical Field

[0001] The utility model relates to the technical field of poultry breeding, and more particularly to a grading device for measuring the particle size of laying hen feed. Background Art

[0002] Feed particle size is often overlooked in poultry production. Feed manufacturers often fail to ensure uniform particle size and thoroughly mix the various feed ratios during the production process. Particle size can vary, from very fine to very coarse. Different grinding methods can also lead to different particle distributions. Even when the overall nutritional content of the feed is similar, varying particle sizes can affect feed digestion and absorption, as well as poultry performance.

[0003] Layer feed is typically a mixture of large and small pellets, with chickens preferring large pellets. These large pellets are primarily crushed corn, providing energy. Smaller pellets primarily contain amino acids, phosphorus, vitamins, and minerals. This standard requires that feed or raw materials must be passed through 14 smaller sieves for 10 minutes, calculating the geometric mean of the feed particles and the uniformity of the feed particle size (standard deviation or coefficient of variation). The coefficient of variation for a properly formulated feed should be less than 10%. This method is only suitable for large feed processing plants. It is difficult for farmers to conduct convenient and quick particle size testing of feed on the farm.

[0004] Therefore how to solve the above-mentioned technical problems just becomes the problem that the utility model faces. Utility Model Content
