Method for Determining the Optimal Insemination Time for Sows by the Hand-Pressure Technique
The inseminator stands at one side of the sow in estrus, facing the sow's back, extends both hands flat, and gently places them on the sow's back, then gradually presses down with force. At this point, if the sow's back suddenly arches up and there is a sense of upward rebound, press down for another 1-2 minutes; if the sow stands still without moving, without continuous grunting or squealing, then this is the optimal time for insemination; if, when pressing down, the sow's limbs move forward and backward and she makes vocalizations, then it is not the optimal time for insemination.

What is the optimal protein level in fish feed?
Protein is the main nutritional indicator of compound feed for fish, and the protein level directly affects the intrinsic quality of the fish feed. Different fish species and different growth stages have different optimal protein requirements. Too high a protein content not only wastes feed protein resources, but also increases the pressure of pond water quality management. Too low a protein content, on the one hand, causes slow fish growth and poor disease resistance, and on the other hand, delays production timing. Therefore, mastering the optimal protein level of fish feed is of great
