CATDOLL : CATDOLL: Formulated feed for breeding freshwater silver pomfret

Formula feed for breeding freshwater silver pomfret

Freshwater silver pomfret is a feeding fish. In intensive farming such as ponds, cages and running water, freshwater silver pomfret is fed with compound feeds. This is also an important measure to increase production, promote growth and shorten the breeding cycle. Practice has proved that breeding with compound feeds has the following advantages:

1. High nutritional value, suitable for intensive breeding, high yield and management.

2. The feed sources have been expanded. The feed raw materials include cakes and meal, bran, beans, dregs, roughage and animal feed.

3. Feeds with different nutritional ingredients can be prepared according to the type and size of fish to make them most suitable for the needs of farmed fish.

4. Modern advanced processing technology can be used for mass production to meet the needs of fish farming development.

5. Suitable for automatic feeding, which improves labor productivity and is conducive to development in the direction of mechanization and industrialization.

Formulating principles of compound feed:

Although the nutritional requirements of freshwater silver pomfret have not yet been determined, general principles should be mastered when designing and formulating its feed in the future.

1. Nutritionally balanced feed formulas must be formulated based on the nutritional needs of farmed fish and the nutritional value of feed. When formulating, the energy needs of fish must be met first. Protein, fat and carbohydrates in feed are all organic substances containing energy, so as long as these three nutrients are met in fish feed, the energy value is generally easy to meet. The focus should be on the content and proportion of protein and amino acids in the feed to meet the requirements of nutritional standards. In addition, the crude fiber content in the feed should be controlled within the minimum range to avoid a decrease in the digestibility of other nutrients and the total digestibility of the feed.

2. Choose a variety of feed raw materials to match and try to achieve a balance between protein and amino acids. The nutritional value of various feed raw materials has its own strengths and weaknesses. They complement each other and generally have higher nutritional value than a single feed. Appropriate additives should also be selected to improve the nutritional content of the feed and enhance the fish farming effect of the feed.

3. The digestibility of each nutrient in the feed raw materials and the palatability of the feed must be considered. Pay attention to choosing the appropriate feed according to the digestive physiological characteristics, feeding habits and preferences of different fish.

4. When designing compound feed and selecting feed formula, the greatest economic benefit should be sought, taking into account both the source of raw materials and the convenience of storage, transportation and use.

Freshwater silver pomfret feed formula example:

Although the nutritional needs of freshwater silver pomfret have not been studied in depth and are currently in the experimental stage, freshwater silver pomfret has a variety of diets and is not very selective in feed. Different units have selected a variety of feed formulas for production practice and have achieved good fish farming results. Several formulas are introduced below.

The above formula has a good effect after use. In order to improve the utilization rate of the compound feed, green vegetables, melon peels and other green feeds can be fed intermittently while feeding the compound feed, which is beneficial to the rapid growth of freshwater silver pomfret.

Freshwater silver pomfret broodstock and fingerlings are suitable for compound feeds with 30-33% crude protein, and adult fish are suitable for compound feeds with 25%. Since freshwater silver pomfret has a wide range of diets and does not require high levels of crude protein, local areas can formulate cheap, efficient and practical formulas based on local feed raw materials and prices.

Feeding technology of compound feed:

After the fish species and feed are solved, feeding technology is particularly important in fish farming. To achieve efficient use of fish feed and maximum economic benefits, it is not only necessary to have a reasonable feed formula and comprehensive nutrition, but also to a greater extent to rely on correct and effective feeding technology.

For fish fingerlings: fish meal 10%, soybean cake 25%, sesame cake 25%, rice bran 10%, bran 9%, mixed material 13.7%, mixed salt 2%, leftover flour 5%. Vino multivitamin for fish 0.1%, Vino mycotoxin and multimineral 0.1%, Vino compound probiotics 0.1%.

The feed formula of freshwater silver pomfret is as follows: Formula 1: fish meal 40, meat and bone meal 5, soybean meal 36, cottonseed cake 5, wheat bran 2, yellow corn 5, molasses 2, soybean oil 3, vitamin mixture 1, mineral mixture 1. The crude protein content of the feed is 40%, which is used to feed young fish. Formula 2: fish meal 30, meat and bone meal 5, soybean meal 20, cottonseed cake 5, wheat bran 17, yellow corn 16, molasses 2, soybean oil 3, vitamin mixture 1, mineral mixture 1. The crude protein content of the feed is 30.9%, which is used to feed fingerlings.

In fact, it is quite difficult to mix this kind of feed. On the one hand, the selection of its raw materials and the texture need to be carefully selected.
