How to Determine the Harvest Time of Walnuts? A Detailed Guide to Harvesting Methods
Timely harvesting of walnuts is very important. If harvested too early, the green husk is difficult to peel off, the kernel is not plump, the yield decreases, the kernel yield rate is low, the oil yield rate during processing also decreases, and the nuts are not resistant to storage. According to measurements, harvesting 1 day early on average reduces the dry fruit weight by 0.49%, and the kernel weight by

Proper Methods for Processing and Storing Pig Feed
Using appropriate methods to process and prepare feed can increase pigs' feed intake and improve the digestion and absorption of nutrients. I. Selection of Feed Ingredients A complete feed formula alone does not guarantee a nutritionally balanced, good feed. No matter how balanced the nutrition in the formula is, if problems arise with the ingredients or storage, all the effort is wasted. When considering ingredients for formulating diets, farmers often only pay attention to low-priced, easily obtainable materials while neglecting other unfavorable factors. The following issues should be noted when using ingredients:
