Factors affecting the quality and safety of feed products
Feed quality usually refers to the nutritional value of the feed, and the nutritional value of the feed is generally evaluated by chemical components, including moisture, crude protein, and crude fat.
Feed safety includes several aspects, such as feed raw materials containing toxic and harmful substances, contamination during production or processing, and illegal addition of prohibited substances. Daily work mainly monitors illegal additives such as antibiotics, natural toxins, and pollutants.
The main factors affecting the quality and safety of feed products
1. The main factors affecting the quality of feed products
1. Differences in the origin of feed raw materials
My country has a vast territory, and even the same feed material has different nutritional components due to different origins. For example, corn is one of the main raw materials for feed, and corn in different regions has different nutritional components. The same variety of corn, planted in the Northeast, has more sugar, amino acids and protein than those grown in the south due to sufficient sunlight. Corn is higher.
2. The production and processing technology or processing process is different
Raw material cleaning, pulverization, batching, mixing. Pelletizing is the five major processes of feed processing, and each step has a key control point that affects the quality of feed. The precision of the mixer, the mixing uniformity of the mixer, and the management measures such as the modulation or puffing effect in the granulation process are not strictly implemented, which will cause differences in the nutritional status of the feed products.
3.Some feed ingredients are not properly detoxified in the early stage, some plant feed ingredients contain alkaloids, glycosides, nitrites and other toxic and harmful substances, and some animal feeds contain histamine, antithiamine, gizzard, etc. Toxic and harmful substances, if these raw materials without detoxification are used to produce feed products, it is easy to cause poisoning or death.
