Look at the manufacturers. The current feed market is confusing and has a wide variety of products. Generally choose large companies' concentrates. The technology, equipment, and funds of small plants are relatively weak, and it is difficult to ensure high quality and low price in the long term. However, large enterprises are different and quality is guaranteed. At the same time, large factories have more sales points and better after-sales service. Technical personnel will arrive at the point of sale on a regular basis. Give lectures to chicken farmers, release farming technical data, and provide technical services at home. Look at the date. Selecting the manufacturer's concentrates depends on the production date. Any product has a shelf life. The shelf life of the concentrates is generally six months. Feeds that exceed the shelf life cannot be fed. Identify true and false. 1 Look at the packaging: The quality and color of the bags of the same brand should be the same, the descriptions and trademarks on the bags should be clearly visible, and the inferior products should not be. 2 Look at the feed: Look at the shape, color, smell, and evenness of the feed. High-quality products have a high degree of evenness and a specific color and odor. However, poor-quality products have rough processing, poor uniformity, unusual odors, and differences in color and high-quality products. Even feeds have impurities such as bones that have not been completely crushed. 3 do analysis: If you do not rest assured after the above checks, you can send samples to the relevant departments for feed analysis to determine whether the content of each nutrient is consistent with the instructions. Look at the effect. The choice of a good concentrate is to maximize the chicken's growth needs and egg production needs. If the chicken grows fast, the feathers are shiny, the egg production rate is high, and the peak period of egg production is maintained for a long time, indicating that the concentrated material is of good quality and suitable for the breeder. If the chicken grows slowly and the egg production rate is low, it is necessary to analyze whether it is the reason for the concentrated feed, because there are many factors that affect the growth of chickens, breeds, diseases, feeding and management can all lead to slow growth of chickens and low egg production. If it is indeed the reason for the concentrate, the concentrate should also be changed scientifically. It is generally divided into two refuelings. The ratio of the first raw concentrate and the new concentrate is 1:1, and the feed is fed for about 5-7 days. The second time, all the new brand concentrates are used so as to avoid the replacement of the concentrate. The stress response produced by the material and the egg production rate decreased. Compare it. In the production of chickens often compared with the previous batch of chicken used in the enrichment of the material, under the premise of excluding other factors, can only draw general conclusions. To reach an accurate conclusion, chicken farmers must conduct comparative tests on the same batch of chickens, that is, divide the chickens into two groups (equal numbers in each group, the egg production rate is as close as possible, and group differences are as small as possible), and other conditions are the same Next, using two brands of concentrate, according to the growth, egg production rate and the time of peak egg production, to determine the advantages and disadvantages of the two brand concentrates (note that the contrast test generally takes at least a month, the time is too short accurate).
