First, different feeding methods are adopted according to different growth stages of the grass chickens. The chicks began eating with concentrated ingredients. From the 4th day of age, the chicks were able to add about 20% of chopped green vegetables to their concentrates. Because of its small esophageal capacity, it should be fed less frequently, so that chickens form a good condition for the food to reflect, so as to lay the foundation for the food in the pasture from the grassland food. When the grass chickens are 36-80 days old, they can adopt grazing and feeding conditions. During the grazing period, they should pay attention to early and late feeding of grass chickens with full price ingredients. If there are no stocks that are stocked, green roughage can be added to the diet in a 1:1 ratio. The feeding method is to feed the chickens with a single full price feed, and then put an equal amount of green roughage in the bucket for 1 hour so that the chickens can feed freely. Grass-fed chickens can reduce the amount of green roughage feed 15 days before slaughter, so as to help shorten the fattening period and increase daily weight gain.
Second, the use of green roughage should be diversified to ensure quality. Any kind of green roughage does not have a comprehensive nutritional value. If it is used in various ways, it can play a complementary role in improving the utilization of various amino acids in feed, and at the same time, reduce feed costs. Such as legumes and grass feed, aquatic feed and sweet potato vine powder or flour, but avoid straw powder and oyster shell, rice husk, reconstitute with.
Third, pay attention to the processing and modulation of green roughage. The green roughage is best chopped, beaten, and fed with concentrated feed. If it is stored for a long time or it is boiled, nitrite poisoning and even death of grass chickens can be caused. Roughage such as sweet potato vines, bitter vines, peanut vines, alfalfa, champagne grass should be sun dried immediately after harvest, and try to maintain its integrity, it can be silage or processed into a dry powder, remove and mix with the fine material when needed.
Fourth, guarantee the uniform supply of green roughage throughout the year. Affected by the seasons, the supply of green roughage for all seasons in many areas of our province is not balanced. However, as long as we strengthen the planning of pasture planting, this problem can be solved. Such as spring planted chicory, Rumex, wolfberry; early summer champagne grass, grain pods; winter species purple Yunying, winter cabbage, yellow cabbage, can also be some autumn roughage dried or silage up, for Use off-season.
