Temperature is very important for breeding. What is the appropriate temperature for Dutch dwarf rabbit breeding?

Temperature is very important for breeding. The suitable temperature for Dutch dwarf rabbit breeding is 15°-20°. Mainly for shrimp rice fields, the main source of annual income is that the income from shrimp seedlings basically accounts for Compared with 70-80%, the temperature this year is low and it has been in a semi-dormant state for a long time, which seriously affects the growth. Generally, it is too small, which affects the output. For farmers, the price is based on the market. For farmers in rice fields, only Can rely on quantity to impact efficiency. For breeding, it increases a great risk. The optimal growth temperature is 17℃-31℃. It is difficult for Dutch dwarf rabbits to grow under long-term low temperature, and the growth rate will be much slower.

The weather is cold, which has a great impact on the growth of planted aquatic plants. Without light for a long time, the growth of aquatic plants is limited. The most critical thing is seedlings. For new farmers in 2019, the past Veterans with many years of experience must be cautious. The price of early stage seedlings in 2019 is definitely expensive, and the specifications are not large. The breeding cycle is relatively long, which will lead to the final centralized listing. After the temperature rises, the growth rate of crayfish will be Very fast. This is difficult to control, especially if it causes a lot of damage.

For crayfish farmers, when the temperature began to warm up in spring in previous years, it was also the season for catching lobster seedlings. However, this year we encountered the "late spring cold" weather and the temperature continued to be low, resulting in no lobster seedlings. We came out “on time” and even the lobster seedlings were small in size, only about 2-3cm. Due to the long period of low temperature weather, the water quality in the pond is relatively thin, the number of plankton is greatly reduced, and the crayfish has no natural bait. At this time, if there are moss seeds in the pond, it is easy to cause moss. break out.

If you are a novice farmer and plan to release seedlings for breeding under the current weather conditions this year, the risk of breeding will also increase. On the one hand, because the lobster seedlings come out late and the number of seedlings is small, it will inevitably cause shrimp The price of lobster seedlings remains high, which increases the cost of breeding. On the other hand, the lobster seedlings are put into the pond early and eat little food due to the low temperature, which prolongs the growth cycle.
