SILAGE

Corn stalks after harvest (especially corn harvesting corn cobs) occupies a very large volume. For efficient utilization of by-products, the TS. Le Dang Danh (Nong Lam University. HCM) studied successfully brewed corn stalks as a food source for cattle reserves

How fresh silage corn stalks

To reduce wastage, stem fresh corn (maize harvesting corn cobs) cut to be incubated immediately, then use the mower into the small trunk of about 2-3cm long, then mix additives may be 0.5 % salt or sugar molasses 5% (compared to corn brewed weight) into a plastic bag sucked air (can avail milking machine) and compacted, each muffs around 10-30kg.

Often brewed corn yellow green salt, sour concentration, also brewed with molasses sugar green-yellow-brown, slightly warm sour smell accompanied by sweet molasses. Also can be incubated with formic acid (limiting mold) corn silage, yellow green in color, slightly sour concentration, very palatable to cattle.

How dry cornstalk silage

Process itself corn silage dry (corn harvest dry corn field) was carried out as follows Corn chopped dried brought, 3-5cm lengths, mixed with additives, can 0.5% saline (salt ratio than cornstalk weight), 5% corn milling or 5% molasses, entered incubated bag of about 4-5kg / bag.

Cut corn relatives in plastic bags, use a vacuum out the air (using milking machines) and fasten it with an elastic band Bag. Preservation of this composting bag not exposed to the sun shining directly. How to 20cm above the ground millet. When incubated for more cornmeal, molasses fermentation to make faster, how to lower the pH below 4 is best for corn storage incubation.

Compare

Both fresh and dried corn stalks at 30 days after incubation, through analysis, nutrient composition of maize itself has not changed much. Dry corn stalks after incubation with dark golden brown, slightly sour smell concentration during incubation, and fresh yellow corn stalks bluish, sour smell strong concentration, aroma of molasses.

After 45 days of incubation fresh corn from 3.9 to 4.3 pH lower than dry corn stalks (pH = 5). This proves even more fresh corn sugar should melt more easily fermented, dried material resolution in the rumen of cows in dry maize corn higher fresh, brewed with molasses separately with the highest resolution.
With silage in plastic bags, preserved corn stalks about 1 year, but the best is to feed cattle silage before 9 months.
