With the rapid development of China's feed industry, there are more and more brands of chicken concentrates, and there are 50-60 brands in the feed market in Jiangsu Hai'an. Faced with numerous brands and various advertisements, how can chicken farmers choose concentrates suitable for their own chickens? The author interviewed nearly a hundred chicken farmers to investigate their views on this, and are summarized as follows:
(a) to see the manufacturers: the current feed market is relatively chaotic, a large number of brands. Select the concentrate first look at the manufacturers, generally choose large enterprises of 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; while large companies are different, with rich production experience, advanced equipment and technology, and quality assurance. At the same time, the big manufacturers have more sales points and better after-sales service. Technical staff regularly visit the sales point to give lectures to the chicken farmers, distribute breeding technical data, and provide technical services at home to protect the farmer's chickens. Since some foreign large feed mills often have branch factories in the local area, chicken farmers must not only look at the manufacturer's brand at the time of purchase, but also make it clear whether the concentrate is produced by a big factory or a factory. Whether there is a difference between the two.
(b) look at the date: the choice of regular manufacturers of concentrates, but also look at the production date. Any product has a shelf life, the shelf life of the concentrate is generally six months, the feed exceeds the shelf life can not be used for feeding, so when you purchase to see the production date and shelf life.
(3) Identification of true and false: Good concentrates are favored by farmers, and the majority of farmers are rushing to purchase them. At this time, counterfeit goods will be produced. Therefore, it is necessary to distinguish between true and false at the time of purchase. specific methods:
1. Look at the packaging: The quality and color of the bags of the same brand should be the same. The descriptions and logos on the bags should be clearly visible, while the inferior products should not be.
2, see feed: see feed shape, color, smell, evenness. 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 are not assured after the above checks, you can sample and send the relevant departments for feed analysis to determine whether the content of each nutrient content is consistent with the written description.
(d) 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 duration of the egg production peak is long, 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, and feeding and management can cause slow growth 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 batches. The ratio between the first raw concentrate and the new concentrate is 1:1, and the feed is fed for about 5-7 days. The second batch is entirely made up of new brand concentrates. Only in this way can we avoid the stress reaction and egg production rate caused by changing the concentrate.
(E) Comparison: 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 needed. 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, 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 branded concentrates, the quality of the two brands of concentrates was judged on the basis of growth, egg production rate, and duration of egg production peaks. (Note that comparative tests generally take at least one month, and the time is too short. accurate). Http://
