The separate pen rearing technique of black porpoise

After the diet of the dolphins is stable, it is generally 15-25 days after birth, depending on the weather, hot in summer for 15-20 days and cold in winter for 20-25 days. Can be divided into ponds for adult dolphin feeding and management. It is generally raised in pools according to body weight and physical strength. In order to prevent the phenomenon of early mating of close relatives, it can also be raised by male and female groups. It can put 5 to 8 animals per square meter, which is convenient for activity, which is beneficial to eat evenly and balance the growth and development. at the same time, it can also make the weak young dolphins recover quickly and catch up with the growth rate of strong black dolphins. In the case of hot weather in summer and lack of green materials in winter, we should pay attention to replenish the black dolphin. For the newly fenced dolphins, they should do a good job of keeping warm and cold in winter and add some dry straw or sawdust to the barn. The windows should be sealed with plastic film, and glass windows should be used if possible.

The feces in the barn should be cleaned frequently, and the residual food in the basin should be cleaned during feeding; wash the basin and water basin regularly and disinfect it. After the feces in the pool are cleaned, the bedding grass or sawdust should be put back in time to absorb moisture. Summer generally does not need bedding grass or sawdust, but after cleaning up feces, it is necessary to disinfect the fence house with quicklime. Prevent cats and dogs from entering or shouting. In order to prevent natural enemies such as rodents from entering the house, rats do great harm to black dolphins. You can place some Qiu's bromine baits around the dolphin house with good results. Be sure to give the black dolphin a quiet, clean and comfortable environment to grow.
