Rapid identification of the quality of several feed ingredients

Feed formula can affect the quality of feed, and the quality of feed ingredients has a significant impact on feed quality. In today's market, feed ingredients are often mixed with some pseudo-miscellaneous substances, which brings certain difficulties to formulation, and causes feed plants and farmers to suffer huge economic losses. Here are some quick identification methods for common feed ingredients.

(I) Fishmeal Fishmeal is a high-quality protein feed. However, the quality of fishmeal on the market is uneven, and adulteration has occurred from time to time.

1. What are the common ways of fish meal adulteration?
Common fish meal adulteration includes: vegetative substances such as rice hull flour, wheat bran, grass flour, rice bran, sawdust, and cottonseed meal and rapeseed meal; animal materials such as feather meal, blood meal, and meat and bone meal; There are nitrogenous compounds such as urea and hinge salt as well as gravel, stone powder, yellow mud and so on.

2. How to identify the quality of fishmeal through the senses?
(1) Visually identify high quality fishmeal with the same color (dry color depth, light natural dry color) and uniform particles. Poor fishmeal is light yellow, bluish white, or dark brown with poor fineness and evenness. If there is brown debris in the fishmeal, it may be the outer skin of the cottonseed husk; there are white and gray or light yellow thread, which may be mixed with feather powder or waste powder of the tanning industry. If the color of fishmeal is darker and darker, there may be a burnt smell, which may be burnt fishmeal.
(2), smell smell high-quality fish meal has a rich salty smell, poor quality fish meal has stench, rancid or Hacha taste, adulterated fish meal has a light smell, oil smell or ammonia. If the number of adulterants is large, it is easy to identify. The fishmeal mixed with cottonseed meal and vegetable vinegar has the flavor of cotton aphid and vegetable amaranth; the fishmeal mixed with urea has a slight ammonia smell.
(3) Hand touch to identify high-quality fishmeal, feel the texture soft and loose. Adulterated fish meal has a rough texture and feels like a bar. Through handcuffs and careful observation, it is sometimes found that yellow sand and feather dust are incorporated.

3, fish meal mixed with bran, peanut shell powder, rice hull flour or sand how to test?
Take a few samples into a clean glass cup, add 5 times volume of water, stir well, and stand still to observe the floating and bottom sediments. If the water surface contains feather fragments or vegetal matter (eg, rice husk flour, peanut shell flour, wheat bran, etc.) or minerals such as sand and stones on the bottom of the water, it means that fishmeal is mixed with such substances.

4. How to test urea in fishmeal?
Some imported and domestic fishmeal were mixed with urea to increase the protein content of the test results, posing as high-grade fishmeal. Identification method can be used burning test: Put about 20g of fish meal on a clean iron sheet, heated to 70 °C with an electric oven, such as emitting a pungent smell of ammonia is likely to incorporate urea.

(2) Soybean meal Soybean meal is the most commonly used protein feed. Due to its large amount, slight variations in its quality may lead to serious consequences.

1. What are the adulteration methods of soybean meal?
The adulterants commonly used in soybean meal are corn, loess, sand, urea and other substances.

2. How does the soybean meal undergo sensory identification?
Soybean pods are in the form of flakes or powder, with aroma of beans, but they should not have spoilage, mildew or coking taste, nor should they have a green bean flavor. Soybean meal can be roughly judged by its appearance color and shell powder proportion. If there are too many shells, the quality is poor. The light yellow color indicates insufficient heating, and the dark brown color indicates excessive heat treatment and poor quality.

3, how to identify soybean meal mixed with loess or sand?
Detection by flotation, first take a few pods into the glass, then add water and stir until the beginning of the precipitation, the mixture slowly poured out, if there is sediment in the bottom of the cup, indicating that the pod or soybean meal mixed with Sand stone. Due to the different processing techniques, loess can be deposited without precipitation, but it is only one of characteristics that makes water yellow and turbid.

(c) How does bran quickly identify bran quality?
Bran is often found to contain talcum powder, rice bran, etc. The hand was inserted into a pile of bran and then withdrawn. If a white powder adhered to the finger and it was not easy to shake off, then it was accompanied by talcum powder. Grab a handful of bran with your hand. If bran is very easy to clump, it is pure bran. Then grab a handful of bran and rub it with your hands, and when you feel your hand is up, you have rice bran; if you have a slippery feel, then you have talcum powder.

(4) Bone meal adulterated with bone powder is often poor in phosphorus and can easily cause livestock and poultry paralysis. Non-degummed bone powder is prone to spoilage and often causes poisoning in livestock and poultry. Fake bone meal is often mixed with stone powder, shell powder, fine sand and other debris.

1. How to identify the quality of bone meal by naked eye?
Pure bone powder is grayish white powder or granular, and some of the particles are honeycombed and emit an inherent odor. Adulterated bone meal has only a few honeycomb particles, or no honeycomb particles, and the bone powder of Becker shell powder is whitish.

2. What other methods can identify the authenticity of bone meal?
Bone powder does not decompose when soaked in water. Some bone powder soaks for a long time and becomes powdery. It settles after standing. In addition, the fine powder of the steamed bone powder and the raw bone powder floats on the surface of the clear water, and the stirring does not sink. However, there are few floating particles of the degummed bone meal.
