Homemade eco dairy cow feed

Preparations: 1. Dig out to the ground a rectangular pit measuring 10 meters long, 3 meters wide and 2 meters deep, and seal the bottom and perimeter with cement to prevent seepage and seepage through the bottom of the ground and prepare the ground for sealing. 2. After the cement tank cools, dry 30% of the corn stalks are cut into 1-3 cm sections with a lawn mower. Humidity is held by hand and no dripping occurs in the fingers. Fermentation work: 1. Distribute the chopped straw into the cement tank. Uniformly spread a layer of urea every 40 cm thick straw layer. 2. After the straw is filled with the cement tank, the top is sealed with a plastic sheet, and the soil is buried tightly around the straw. Sealed straw should be kept away from sunlight and rain as much as possible. In winter, it can be considered indoors or in a plastic greenhouse. The optimum temperature for fermentation is 10°C-30°C, 4-7 days in summer and 10-15 days in winter. Feeding work: 1. When the straw feed has obvious mellow, acid and aroma, it can be used when the texture is soft and moist. 2. Use as much as you like, and use it still closed. Once fermented stalks can be kept fresh for 1-2 years. 3. Mix 60% into each feed.
