Introduction to the steps of fermenting chicken manure as feed by chicken manure starter

The production of pig feed with chicken manure can generally be fermented in plastic bags.

First, the processing method of chicken manure feed.

Collection and preparation of ① chicken manure. Collect fresh chicken manure, pick up sundries, mash and add 5% Mel 10% energy feed, such as corn flour, wheat bran, etc. Yijiayi EM solution 0.5-1%.

② moisture adjustment. The method of anaerobic fermentation requires that the water content of fermentation raw materials is about 60%, fresh wet chicken manure is added with about 10% wheat bran, and its content can basically meet the requirements of 60%. The dry chicken manure needs to be naturally soaked with water for 1 hour, and the wet chicken manure mixed by hand is grasped tightly by hand. When there are water droplets exudating but not dripping, it shows that the amount of water is basically appropriate.

③ filling. The apparatus for anaerobic fermentation can be a cylinder, a cement pool or a plastic bag. When fermenting with a plastic bag, after filling with chicken manure, the remaining air in the plastic bag should be fully discharged and the mouth of the bag should be tied up tightly.

④ fermentation time. When the ambient temperature is 10 ℃-15 ℃, it takes 10 days for fermentation. If it is more than 20 ℃, it will take 5 days. It takes 2 days at 30 ℃.

⑤ pay attention to the problem. A, to master the appropriate water content, the requirement is about 60%. B, to create an anorexic environment, the raw materials must be layered and compacted, especially in the corners and edges, and should be sealed after filling to prevent air from entering. If chicken manure is caked, white and moldy, it shows that it has become moldy and cannot be used to feed animals, otherwise it is easy to cause disease or even death.

Second, the technology of feeding pigs with chicken manure feed.

① decides pigs with chickens.

The feces of 1000 laying hens can be fed by 75 pigs, so the ratio of chickens to pigs is 13:1. If the chicken droppings cannot be collected completely, the proportion of chicken droppings should be in the range of 13, 15, 15 and 1. Most of the modern chickens are raised in cages, on-line or flat with thick bedding materials, and the chicken manure is processed in time within 24 hours to prevent the chicken manure from rotting and reducing the nutritional value. After the collection of chicken manure is fermented and processed, it can be used to raise pigs, but attention should be paid to the proportion.

② diet containing chicken manure.

When preparing diets, because the energy value of chicken manure is low, in order to balance the diet, it is necessary to add more feed with high energy value (such as corn) in pig feed. According to the results of the experiment, the following suggestions are put forward for the proportion of chicken manure: 20mur35kg growing pig, chicken manure accounts for 8% Mel 10% Muv 35kg 60kg pig, Chicken dung accounts for 10% Rue 20%. 60 Mel 100 kg fat pig and chicken manure account for 20% Mel 25%. When matching the diet, you can go through the three stages of checking feeding standards, trial blending and adjustment. Example of ③ feed formula. Fermented chicken manure 20%, corn 48.43%, secondary flour 4.63%, wheat bran 19.69%, bean cake 2.87%, cottonseed cake 3.28%, trace element additive 1%, salt 0.24%, multivitamin 0.01%.
