How to add green roughage to grass chickens

In order to make the grass chickens gain weight quickly and put them out of the slaughter early, some farmers ignore the grass chickens' habit of eating grass and feed a single concentrated feed throughout the period, which increases the cost of grass chickens. With the continuous rise of feed prices, it is necessary and feasible to add a certain amount of green roughage to the diet of grass chickens, but the following issues need to be paid attention to during the addition process:

Different feeding methods are adopted according to different growth stages of grass chickens. Chickens are fed with concentrate, and about 20% of chopped green vegetables can be added to the concentrate from the age of 4 days. Due to the small capacity of the esophagus, it should be fed less frequently, so that the chicks can form a good conditioned reflex for food, and lay the foundation for them to forage grassy food in the pasture after dewarming. When the grass chickens are 36 to 80 days old, grazing can be adopted if conditions permit. During the grazing period, pay attention to supplementing the grass chickens with full-price ingredients in the morning and evening. If there is no condition for stocking flocks, green roughage can be added to the diet at a ratio of 1:1. The feeding method is to feed a single full-price feed to the chickens first, and then put the same amount of green roughage in the feeding bucket after 1 hour, so that the chickens can eat freely. The feeding amount of green roughage can be appropriately reduced 15 days before the grass chickens are released to help shorten the fattening period and increase the daily weight gain.

The use of green roughage should be combined in a variety of ways to ensure quality. None of the green forages have comprehensive nutritional value. If they are matched in various ways, they can complement each other, improve the utilization rate of various amino acids in the feed, and reduce the cost of the feed. For example, legume feed is matched with grass feed, aquatic feed is matched with sweet potato vine powder or flour, but straw powder should not be matched with husk, rice husk, and bran.

Pay attention to the processing and modulation of green roughage. The green roughage is best to be chopped, beaten and mixed with the concentrated feed. If it is stored for too long or is simmered, it may cause nitrite poisoning or even death of grass chickens. Forages such as sweet potato vine, bitter vine, peanut vine, alfalfa and champagne grass should be dried immediately after harvesting, and their integrity should be kept as far as possible.
Ensure the uniform supply of green roughage throughout the year. Affected by the seasons, the supply of green forage in many areas in our province is not balanced throughout the seasons, but as long as the planning of forage planting is strengthened, this problem can be solved. For example, plant chicory, Rumex, and alfalfa in spring; plant champagne grass and amaranth in early summer; plant vetch, winter cabbage, and cabbage in winter. You can also dry or silage some green roughage in autumn for Use off-season.
