With the rapid development of China's feed industry, more and more brands of chicken concentrate are used. Faced with numerous brands of concentrates and various feed advertisements, how can chicken farmers choose their own chicken concentrate? The author believes that "three comparisons and one comparison" should be done:
Three look
Look at the manufacturer's choice of the concentrates of the big plants. The technology, equipment, and funds of small plants are relatively weak, and it is difficult to ensure the quality and cheapness of products for a long period of time. Dachang has a wealth of production experience, equipment, and advanced technology, and the quality is guaranteed. At the same time, there are many sales outlets in large factories, and after-sales service is also relatively good. Technical staff regularly visit the sales outlets to give lectures to chicken farmers, provide technical information, and provide technical services at home to provide escort for the raising households. Some foreign large feed mills often have branch factories in their localities. When purchasing chickens, chicken farmers must not only look at the manufacturer's brand, but also make it clear whether the concentrated material is produced by a big factory or a factory. Whether the two are different.
Looking at the date of the selection of regular manufacturers of concentrates, but also look at the production date and shelf life, beyond the shelf life of feed can not be fed.
Look at the effect of selecting a good concentrate is to meet the chicken's growth needs and egg production needs. If the chicken grows fast, the feathers are shiny, the egg laying rate is high, and the peak egg production time is maintained for a long time, indicating that the concentrated material is of good quality and is suitable for the chicken feeding of the breed; if the chicken grows slowly, the laying rate is low, it is necessary to analyze whether the concentration is concentrated. Material, if it is caused by the concentrate, the concentrate should be changed scientifically.
A discrimination
That is to say, 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. 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. Do the analysis: If you do not rest assured after the above checks, you can sample and send relevant departments for feed analysis to determine whether the content of each nutrient component is consistent with the instructions.
a contrast
There are many factors that affect chicken growth and egg production. To determine whether a certain brand of concentrate is most suitable for this breed of chicken, a comparative test is required. In the production, the chicken farmer often compares with the concentrate used in the previous batch of chickens, and can draw general conclusions on the premise of excluding other factors. To reach an accurate conclusion, the chicken farmer must conduct a comparative test on the same batch of chickens, that is, divide the chickens into two groups (the number of groups is equal, the egg production rate is similar, the group difference is as small as possible), and other conditions are the same Next, using two brands of concentrates, the quality of the two brands of concentrates was judged on the basis of growth, egg production rate, and the duration of egg production peaks.
