With the rapid development of the poultry breeding industry, most poultry farmers have gradually realized the role of compound feed in poultry production, and more and more use of compound feed to feed poultry, but little is known about the knowledge of compound feed. There are some misunderstandings when purchasing compound feed, which affects the improvement of breeding efficiency.
Misunderstanding 1: Feed color yellow must have nutrition
The compound feed pays attention to the comprehensiveness and balance of its nutrients, and the depth of the feed color is not directly related to the nutritional value of the feed itself. In the plant protein feed, the color of the bean cake (粕) is light yellow, and its nutritional value and palatability are relatively good. People think that the feed color is light yellow, that is, the bean cake (粕) is used in a large amount and the quality is good. The color of the cake (粕) cotton cake (粕) is relatively deep, and the palatability is slightly poor, which is considered bad. This is actually a misunderstanding. In fact, as long as it can be scientifically and reasonably matched, it can still be combined with a comprehensive and balanced diet, and the cost can be reduced accordingly, and better economic benefits can be obtained. In order to pursue high profits, some feed manufacturers use the psychology of the masses to pursue the color of feed, add chemical pigments in production, and shoddy to expand sales, and harm consumers, farmers must not prevent.
Misunderstanding 2: The concentration of feed aroma must be
The odor of the compound feed should be based on the inherent odor of the feed. In the compound feed, the flavoring agent, such as flavoring agent, sweetener, umami, salty agent, etc., can improve the palatability of the feed, stimulate the appetite and feed. Conversion rate to promote poultry growth. However, they only change the physical properties of the feed. The nutritional value of the feed itself is not great. If one-sided pursuit of sensory effect, excessive addition may have some toxic side effects (such as salt poisoning), and even affect the quality of the carcass and reduce its commodity utilization. rate.
Misunderstanding 3: The amount of feed and big fish meal is not bad
The high-quality fishmeal has a relatively high nutritional value in animal protein feed. The various amino acids are balanced, have good palatability, and are easily digested and absorbed. It is a good protein feed, but because of its limited production, the price is relatively high. The feed mill generally does not mix too much, but adds a fish-flavored attractant such as fish aroma to increase the fish's aroma of the feed, which means that the size of the fish's aroma does not fully prove the feed. Users should have a clear understanding of the amount of fishmeal. With the development of science and technology, practice has proved that in the absence of fishmeal, it can also cooperate with the full-price high-nutrient level compound feed, and achieve a good practical feeding effect.
Misunderstanding 4: high protein content, feed is not
Protein is the most basic substance of life activities, and it is an essential nutrient in feed. There must be enough protein feed in poultry diet to meet its growth and development needs. But not the more protein, the better, because the body's absorption and utilization of protein is different in different growth stages. Too much protein supply, not only can not all the poultry be converted into body protein, but also through the body's series of operations. It is consumed as an energy feed. This is not only a waste of protein feed, but also increases the burden on the kidneys of poultry and affects the health of poultry. Especially in the current lack of protein feed, it is even less important to add excess protein feed to poultry diets.
So, how to buy compound feed to ensure successful farming? The following five aspects of the feed identification analysis:
1. Look at the color of the feed. A certain type of feed of a certain brand, its color is relatively stable for a certain period of time. Due to the different color of various feed ingredients, different manufacturers have different formulations. Therefore, it cannot be measured by a uniform color standard, but if we change the color too much when purchasing the same brand, it should be alert.
2. Smell the smell of the feed. A good concentrate should have a pure fishy smell rather than an odor or other odor. Some inferior feeds add a higher concentration of flavor in order to cover the musty smell of some metamorphic raw materials, so some feeds are not good feeds, although they are particularly fragrant.
3. Look at the uniformity of the feed. The quality feed mix of regular manufacturers is very uniform, and there will be no polarization. The inferior feed is difficult to ensure the quality of the feed due to the simple processing equipment. From the outside, each part of the feed has no need to grab one. See the difference.
4. Look at the packaging trademark. The formal manufacturer's packaging should be beautiful and tidy, the site, telephone, and adaptable varieties, and have trademarks registered in the industrial and commercial department. Many of the fake and shoddy products on the packaging site, the phone is fake, there is no registered trademark, the registered trademark on the upper right has R mark.
5. Look at the date of production. Although some feeds are high-quality feeds produced by regular manufacturers, if the shelf life is exceeded, the feed will inevitably deteriorate. Even if the storage is good, the potency of vitamins and other nutrients in the feed will be reduced, which will affect the feeding effect. It is also important to note that it is best to purchase the feed once in the shelf life.
