Application of spray dried Blood Cell protein Powder in Suckling Pig Feed

What is the utilization rate of spray dried blood cell protein powder in teaching trough feed and suckling pig feed, what is the appropriate dosage, and what is the actual use effect? Experts are welcome to express their opinions and suggestions, and doers are also welcome to participate in the discussion-they are not very palatable and dare not use them. -- I heard that there is a broken blood cell protein powder. I wonder if it is a propaganda selling point created by the manufacturer. if so, what is the effect of using it? Based on my experience, I suggest to you: put less than 5% of the material in the teaching slot, and if the color can pass, you can slightly increase the dosage, preferably no more than 8%. In the suckling pig feed can be added to 2-3% (without color requirements), the effect is very good, red fur, fast growth, is a high-quality protein raw material! -- the effect is not bad.-- never used it. I don't know-- thank you. I'll try it out, too.
