Method for processing chicken green green feed
1. Chopping method: The simplest processing method for green and green feed when chopping is used for farmers to raise chickens in small quantities. After chopping the greenish feed, it is beneficial for the chicken to swallow and digest.
2, drying method: dried pasture and leaves after crushing and processing, can be used as raw materials for chicken diet to supplement the crude fiber, vitamins and other nutrients in the diet. The harvesting period of green and green forage is as follows: from heading to flowering, legumes from early flower to full bloom, and leaves in autumn. The drying method can be divided into natural drying and artificial drying.
Natural drying is to expose the forage grass in the field for 5 to 7 hours, but when the moisture content is reduced to 30% to 40%, it is moved to the dark place and dried. When the water content drops to 16% to 17%, it can be used.åž› or packaged for storage. When stacking, vent holes should be left in the middle of the stack. In the northern part of China, the moisture content of hay can be stored within the limit of 17%, and should not exceed 14% in the southern part. The natural dryness of the leaf greenish feed should be placed in a well-ventilated place, and should be frequently flipped to prevent heat and sun. So as not to affect the quality of the product. When the water content falls below 12%, the pulverization can be carried out. After smashing, it is best to use a nylon bag or a plastic bag to seal the package for storage.
There are two methods of artificial drying: high temperature drying method and low temperature drying method. The high temperature drying method is carried out at 800 to 1100 ° C for 3 to 5 seconds to reduce the water content of the green feed from 60% to 85% to 10% to 12%; the low temperature drying method is to use 45 to 50 ° C for several hours to make the green The feed is dry.
The artificial drying of the green-green feed can ensure that the green-green feed can be harvested at any time, dried at any time, processed into grass powder at any time, can reduce mildew, and can be made into high-quality hay or hay powder, which can preserve 90%-95% of the green feed nutrient. Only 40% of the green feed nutrients can be maintained, and the loss of carotene is exhausted. However, the manual drying process requires high requirements, is technically strong, and requires certain mechanical equipment and costs.
