1. The yellow color of the feed does not necessarily have a nutritious compound feed that emphasizes the comprehensiveness and balance of its nutrient content, and the depth of the feed color does not have a direct relationship with the nutritional value of the feed itself. In the vegetable protein feed, the color of the bean cake is light yellow, and its nutritional value and palatability are relatively good. People think that the color of the feed is light yellow, that is, the amount of the bean cake is high and the quality is good. The color of cakes and cakes was relatively deep and the palatability was slightly poor. This is actually a misunderstanding. In fact, as long as it can be scientifically and reasonably collocated, it will be able to produce a feed that is fully balanced and nutritious, and it will be able to reduce costs and achieve better economic benefits. In order to cater to people's "loyal" mentality, some feed production enterprises add some chemical pigments to the production process, shoddy, expand sales, and harm consumers.

2. The feed has a strong aroma and the quality is not necessarily The odor of the compound feed should be based on the inherent smell of the feed itself, and appropriate amounts of flavoring agents such as flavoring agents, sweeteners, umami agents, salty agents, etc. can be added to the compound feed. Improve feed palatability, stimulate appetite and feed conversion rate, and promote the growth of livestock and poultry. However, they only changed the physical properties of the feed and had little nutritional value to the feed itself. If one-sided pursuit of sensory effects, excessive addition may cause certain toxic and side effects (such as salt poisoning, etc.), and even affect the quality of the carcass and reduce the utilization rate of the product. .

3 feed has a smell, not necessarily fish meal

The nutritional value of high-quality fishmeal in animal protein feeds is relatively high, various amino acids are relatively balanced, palatability is good, and it is easy to digest and absorb. It is a good protein feed, but due to its limited output, the price is relatively high. Generally, the amount of feed used by the feed mills will not be too high. Instead, it will add fish flavors such as fish flavors to increase the fish flavor of the feed. That is to say, the size of the fish flavor in the feed does not fully prove the feed. Users should have a clear understanding of how much fishmeal is contained.

4. High protein content, feed is not necessarily good

Protein is the most basic substance in life activities and it is an essential and important nutrient in feed. In animal and poultry diets, there must be enough protein feed to meet its growth and development needs. But not as many proteins as possible, this is because at different stages of growth, the body's absorption and utilization of proteins is different. Too much protein is supplied, and not only can livestock and poultry not fully convert into body proteins, but also through a series of organisms. Operation, and then consumed as energy feed, this is not only a waste of protein feed, but also increased the burden on livestock and poultry, affecting the health of livestock, not worth the candle. Especially in the current situation of relatively lack of protein feed, more should not be added to animal feed diets.

5. The feces will be black after feeding.

Identify the merits of feed, mainly depends on the effect after feeding. However, some farmers often mistakenly think that the feces after feeding is black and the feed is good. In fact, this may be due to the addition of high doses of copper to the feed and does not necessarily indicate that the feed is of good quality.

6. Sleep after sleep, hard to say high quality

Pig farmers always want pigs to sleep and eat, which can reduce energy consumption, save feed, and promote growth. For this reason, some feed manufacturers have violated the regulations by adding sedatives and hypnotics to the feed so that pigs can eat and sleep; once the pig has eaten such feed, it will reduce the quality of the meat and thus people's food safety.

7. Redness after feeding, quality is difficult to guarantee

The addition of high-dose arsenic in the feed will cause capillary expansion in the pigs, increased capillary permeability, and reddening of the skin. However, the excessive addition of arsenic in feeds is in violation of national regulations and is not conducive to environmental protection and people's health.
