Chicken manure is a kind of protein supplement with high quality and low price. Its dry manure contains 15%-30% of crude protein, 10%-16% of crude fiber, 8%-10% of various Amino Acids, and 1 kg of chicken manure. Crude protein content is equivalent to 600 grams of concentrate, but the crude protein in chicken manure has 50% of non-protein nitrogen and is present in the form of uric acid with low energy and an ash content as high as 25%-35%. Therefore, pay attention to the processing method to increase the utilization rate. (1) Processing of chicken manure. 1 Drying: Spread the chicken excrement evenly on the concrete floor, air dry naturally, make the moisture content of the chicken manure below 13%, and the condition can be dried by a dryer. 2 Fermentation: Add rice bran, bran, grass powder, crop straw powder, etc. to the chicken manure, add appropriate amount of water, and put it in a cylinder, pit or plastic (10140, -140.00, -1.36%) bags, press tightly and seal it. Fermentation for 3-5 days can be used to feed pigs. 3 Silage: Mix 60% chicken manure, 30% straw powder and 10% bran, keep the humidity at 60%, and store silage for 30-50 days. (2) The amount of chicken droppings. Piglets can be added from 5% to 10%; fattening pigs can be added from 15% to 30%. However, when chicken manure is used as feed, it is necessary to collect non-polluted fresh chicken manure in the non-epidemic area; second, more grain feeds should be added to increase palatability and mineral balance; thirdly, chicken manure should have high ash content. The total amount of ash in the grain should not exceed the critical level; Fourth, chicken manure should be stopped 15 days before the fat pigs are slaughtered.
