There are many ways to identify the advantages and disadvantages of feed: appearance inspection, chemical identification, microbiological identification, screening, magnifying glass, animal testing, physical identification (including microscopic identification). Here is the introduction of the appearance inspection method, which uses the eyes, nose, tongue, ears, and touch five sensory organs. This is the simplest and most direct method of inspection.
A look: Look at the packaging bag or label, mainly to see whether the feed name, nutrient composition, analytical guarantee value, net value, net weight, production date, shelf life, plant name, site and standard, etc., to see the shape of the feed, particle size, color , Uniformity, presence or absence of foreign matter, whether it is treated with overheated coking metamorphic discoloration, whether it is agglomerated, with or without insects, and with or without mold.
Two news: if the feed is moldy and spoiled, the protein is decomposed, the oil is rancid or the scorching occurs due to overheating.
Three tastes: A little feed sample is placed on the tip of the tongue to determine the drying procedure (moisture content) or presence of odor, presence of irritation, and presence of grit.
Four touch: Use your hands to feel the texture and dryness of the feed.
Listening: Put the feed in a wide-mouth bottle to shake and hear a crisp sound, indicating that the moisture content is low and dry.
The high-quality compound feed is free of musty, non-irritating, oily aroma, no foreign matter, uniform particles, and low moisture content and dryness.
The above methods combined with application are simple and easy to master. However, the reliable method is to look at the growth and development of livestock and poultry, the rapid increase in daily weight, and the quality of livestock products when you use the feed, indicating that the feed is good.
