Feeding and management techniques of adult black dolphins

separate pond rearing

Should be based on the size, strength of separate pool breeding, so that administrators management. In addition, in order to prevent close relatives or early mating, heterosexual males and females of the same parent are kept separately.

rational feeding

Adult dolphin feed should be mainly green feed, supplemented by concentrate (such meat is very delicious), morning and evening once, green feed daily amount of 250 g/each, concentrate each about 25 g, try to do regular, quantitative. If the green material is insufficient for a long time, it will lack vitamins and cause hair loss. Pay attention to vitamin supplementation. The formula fed should be relatively stable. About 10 days to feed heat-clearing and detoxifying herbs, such as Leigong root, piercing even appetite to prevent pneumonia, reduce disease, and if you choose to do commercial dolphins, it is best to stock, so that the meat is more compact, delicious.

heatstroke prevention and cooling

When the temperature exceeds 37℃, the black porpoise shows restlessness and difficulty in breathing. At this time, measures should be taken to prevent heatstroke. Specifically, do the following:

1, ventilation, open all doors and windows.

2, conditional installation of fans or exhaust fans.

3, pay attention to density: each pool put 2~3 is only good (0.3 square meters of pool).

4. Wet sandbags in the breeding pool, pour cold water 1~2 times a day at noon, or splash water in the corridor to cool down.

5. Shade the top of the breeding house.

6. Feed more juicy feeds, such as watermelon peel, sweet potato, sweet potato, carrot, vegetable leaves, etc.

Freezing and keeping warm

Before winter, we should feed enough nutrient-rich feed, do a good job of fattening and improving physique and cold-proof. After winter, we should make the doors and windows of the porpoise house into curtains with cotton felt, put down curtains to prevent cold wind from entering, cushion soft grass or cloth in the pool, so that the porpoise can warm up inside; At the turn of winter and spring, the temperature is changeable, and the porpoise is easy to catch cold and die. Pay attention to the weather forecast, take measures to stabilize the temperature in the house and prevent low shouting.
