Black carp farming feed formulas are mainly based on highland barley, with different ratios at each stage

AbstractThe farming feed formulas for black carp are mainly made by combining barley, corn, soybean cake, fish meal, wheat bran, crude protein, silkworm pupae, rapeseed cake and wheat bran in different proportions, and the feed ratios for black carp also differ to a certain extent at different farming stages.

Feeding methods for black carp

1. In the process of farming black carp, it is generally better to feed them corn, wheat, soybean cake and rapeseed cake, among which the feed for black carp is mainly river snails, and only by feeding reasonably can we benefit the growth of black carp.

2. At the two-year-old fish stage, feeding is generally carried out from 7-9 am and 4-7 pm every day, mainly with highland barley feed such as wheat and corn. Feeding should not only be done at fixed times, but also at fixed locations; put the feed into the feeder in time so that it can be fed evenly, and the daily feeding amount is about 4% of the pond body weight. When feeding, we can also combine river snails, feeding them with highland barley feed at a ratio of 5:1.

The black carp farming feed formulas are as follows:

1. Feed formula composition: silkworm pupae 30%, rapeseed cake 10%, barley 20%, dried grass meal 40%, feed coefficient 3.

2. Feed formula composition: cotton cake 30%, soybean cake 10%, rapeseed cake 5%, green dried grass 40%, fish meal 5%, naked barley 5%, silkworm pupae 5%, feed coefficient 3.

3. Feed formula composition: soybean cake 47.5%, fish meal 35%, inorganic salts and others 16.5%, yeast 1%, feed coefficient 2.26.

5. Feed formula composition: fish meal 5%, local flour 10%, yeast 5%, rapeseed cake 10%, soybean cake 35%, wheat bran 18%, corn 15%, soybean oil 1%, crude protein 27.4%, multivitamins 0.15%, inorganic salts 1%.
