Complete Collection of Concentrated Feed Formula Tables, Ingredient Ratios at a Glance

Concentrated feed refers to feed made by mixing various protein ingredients with a certain proportion of additives according to livestock and poultry feeding standards. So what is in a concentrated feed formula table?

1. Concentrated Feed Formula Table

At present, there are many kinds of concentrated feed on the market, each with its own recommended formula that has been calculated. These recommended formulas are generally scientific, but it cannot be denied that some individual recommended formulas are not ideal. At present, it has been found that some farmers change the formula at will, mainly as follows: one-sidedly increasing the amount of soybean meal, believing that feed with high protein is good in quality and that livestock and poultry grow quickly, but in fact the result is contrary to their wishes. If some areas lack a certain feed source and need to change the recommended formula, it should also be adjusted according to the original formula, or the manufacturer should be asked to test the replacement new feed source and re-formulate it.

Moderate feed particle size not only ensures that the feed intake of individual livestock and poultry is consistent with the nutritional level ingested, but also prevents the occurrence of metabolic diseases and improves feed conversion. However, some farmers grind feed sources to too large a particle size, and the feed coarseness for small broilers exceeds 5 mm. Feed coarseness should be: young chickens below 1 mm, medium chickens above 1 mm, large chickens 2 mm (pelleted feed 4.5 mm), adult chickens 2-2.5 mm (pelleted feed 6 mm).

The added amount of concentrated feed is only 5% or 6%, while 95% or 94% of the bulk ingredients are feed sources. At present, the quality of feed sources on the market varies greatly, and some are even adulterated. If such high-moisture, low-protein soybean cake is used, the feeding effect can be imagined. The following feed source quality standards are recommended.

Corn: moisture <14%, protein >8%, aflatoxin <50ppm. Soybean meal: moisture <12%, protein >44%, urease activity 5%-25%.

Wheat bran: moisture <13%, protein >14%, crude fiber <12%. Fish meal: moisture <10%, protein >55%, salt <3.5%, free of Salmonella, Escherichia coli, etc.

2. Use of Concentrated Feed

Concentrated feed refers to feed made by mixing various protein ingredients (such as fish meal and soybean meal) with a certain proportion of additives according to livestock and poultry feeding standards. The protein content in concentrated feed is above 35%, and the contents of various essential amino acids, vitamins and inorganic salts are relatively sufficient, so no additional addition is needed.

Some farmers have their own feed ingredients such as corn, rice and wheat, and can choose different concentrated feeds according to the needs of livestock and poultry at different growth stages to prepare different series of complete feed. The proportion of concentrated feed in the daily ration of livestock and poultry varies according to its nutritional content, and generally can account for 25-40%. The proportion for the daily ration of young poultry or young livestock is: corn 60%, wheat bran 5%, concentrated feed 35%. The proportion for the daily ration of growing livestock and poultry is: corn 65%, wheat bran 10%, concentrated feed 25%. Livestock and poultry in the fattening period are mainly raised with high-energy and low-protein feed, so farmers only need to add an appropriate amount of concentrated feed to the energy feed to obtain good feeding results.

Different concentrated feeds have different formulas, but their simple and convenient use makes them very suitable for small farms and farming households.
