In animal farming, feed costs account for about 70% of the total cost. Commonly used feeds generally include compound feeds, concentrated feeds, pre-mixed feeds, concentrate supplements and additives, etc., with a wide variety of brands and brands. Therefore, how to properly purchase feed according to the scale, conditions and funds of the breeding is the key to obtaining the best economic benefits, which is related to the success or failure of the aquaculture industry.
Various feed characteristics The compound feed refers to the finished feed that contains the nutrients that can fully meet the growth needs of livestock and poultry and can reach a certain level of production. The advantage is that it can be directly used without any other ingredients, and is convenient to use. The disadvantage is high cost. The specific performance is as follows: processing costs increase the price of feed costs, a large amount of raw material storage costs increase the cost of feed costs, interest on raw materials purchase funds increases the cost of feed, and a large number of marketing and management fees increase the feed. cost price.
The concentrated feed is completely priced to remove the energy feed such as cereal feed and its by-products (corn, sorghum, bran, wheat, barley), which is a concentrated material. The addition ratio is generally 20% to 40%. The advantage is that it is easy to use and easy to grasp the appropriate formula ratio.
The premixed feed concentrates to the vegetable protein raw materials such as cakes, and the remaining part is the premix. The addition ratio is generally 0.5% to 10%, and the most common market is 5% premix. Its advantages are convenience, low cost and easy storage. It can be used according to the scientific premix of the feed experts. It is now available to form a reliable, scientific, low-cost full-price material. The disadvantage is that it is more time consuming.
The disadvantages of feed additive additive are mainly: the quality of the additive is not guaranteed, as long as one problem occurs, the whole ingredient completely fails; the additive is less, it is difficult to achieve uniform mixing, and the safety is not guaranteed; the use of additive ingredients takes time Labor, whether it is purchased or added, it is inconvenient; the balance and content of various nutrients of various kinds of additives are difficult to guarantee, and the principle of full price balance of feed is violated.
Specific use principle In order to obtain the desired benefits, the feed industry must proceed from its own reality, take it seriously in the important part of feed purchase, and carefully calculate it in order to exchange low input for high efficiency. What kind of feed is used for breeding, depending on the availability of local raw materials, refer to the following purchasing principles:
1. The local production area of ​​agricultural and sideline products such as corn, cakes and bran can be easily purchased from the local area. It is not necessary to purchase concentrated materials. It is most suitable for the premix of about 5%.
2. The local rich corn, but not rich in cake products, suitable for 20% ~ 40% concentrated materials.
3. Non-agricultural areas where local feed ingredients are poor, suitable for full-price materials.
4. Additives are suitable: 1 million households are extensively raised, and the analogy raises several pigs, dozens of chickens, dozens of ducks, and several cows. 2 The special stage of livestock and poultry: high-yield period, young hatch period, emergency period, disease stage and other stages that need to strengthen nutrition.
In addition, according to the scale of breeding, the number of animals such as farmers is small, and the conditions are simple, and the compound feed which is convenient to use can be purchased. Large-scale farms have good mixing conditions and can choose concentrated feed, pre-mixed feed and feed additives. However, no matter which type of feed is purchased, it should pay attention to the brand, quality, reputation and service of the feed, and comprehensively check whether the outer packaging of the feed, the feed label, the production license, the product approval number and the production registration number meet the requirements. Preventing the use of unqualified inferior products can guarantee the success of the aquaculture industry.
