"Look" (see the color of the feed, the uniform condition of the particles): The full-price fish compound feed is the main raw material of fish meal, soybean meal, rapeseed meal, cotton alum, premix (including trace elements), etc., evenly mixed according to a certain proportion Granulation. The appearance color of the feed has the natural color of the raw material and is generally dark brown or brown. If there are more fishmeal and soybean meal, the material color will be slightly yellow, and when the mixture is more, the material color will be dark red. Different growth stages of the fish should use different specifications of pellet feed, as the same specifications of the fish feed product should be uniform in particle size, surface gloss and bright, section incisions are smooth, the particle length is generally 1.5 to 2.5 times the particle size. If the ratio of the length and the particle size of the fish feed is out of balance, the palatability of the fish to the food will be seriously affected and the feed will be greatly depleted. "Smell" (smell the odor emitted by the feed): Full-price fish compound feed is made by mixing various raw materials and steam curing, and generally has a faint scent and smell of fish. Added antibacterial drugs—Allicin has a garlic-like feed; Fish and fish flavors that add fishy fish and fish flavors (instead of fishmeal) have a fishy nose that is soaked in water and soaked in water for a period of time. The smell of fish immediately reduced or disappeared. "Blow" (check the fineness and water resistance of the feed): The method is to grab a handful of feed into the water, observe the time when the feed is dispersed, and check the thickness and uniformity of the feed. The fish (green, grass, alfalfa, cockroach, squid, etc.) that we generally raise are all fishes. The digestion and absorption of food is in the intestine, and it is mobilized by the intestines. It is digested and absorbed by the action of digestive enzymes. This requires that the finer the feed particle size, the better the finer the utilization. The emptying time of fish intestines is generally 1.5 to 2 hours. The time for the feed to be dispersed in water is 3 to 5 minutes, and feeding 2 to 3 hours can achieve the purpose of not wasting the feed. “Cook†(feeling the taste of the feed, the content of impurities): Although the fish eats feed, it is swallowed, but the good or bad taste is the main factor affecting their feeding behavior. Through the tactile sensation and taste of the oral cavity, we can feel the hardness, impurities (if sand, mud) and odor of the particles. If there is a feeling of decayed teeth or dirt, it is proved that the feed contains sand, dirt and other impurities; if there is bitter, acid, astringent and other odor, indicating that there is mildew in raw materials or finished feed. In general, judging the quality of a kind of feed quality should be considered from the aspects of appearance quality and internal nutrition, and evaluated from the scale of the enterprise, equipment, technology, and manpower. Only by selecting high-quality and high-efficiency feed can we obtain high benefits. booster cable has four giant alligator clamps with strong jagged teeth and springs for excellent grip force.
