Corn silage is used as a high quality fodder in many dairy farms and in some fattening farms. This product is very popular due to its high performance, good digestibility, high energy and ease of adaptation to mechanized harvesting and feeding. Fodder corn can be cultivated ideally in many regions of the country as a second crop after the fall crop. Ensiling is necessary to preserve harvested forage corn. The purpose of making silos is to preserve the harvested product by anaerobic (oxygen-free) fermentation. This process uses bacteria to convert soluble carbohydrates into acetic acid and lactic acid, or "souring" the product. In a completely sealed silo, the product can be preserved for a long time without losing quality. To produce a high quality silage, it is necessary to carefully plant, store and harvest silage corn.
Although sunflowers are commonly grown for seed production, they can also be used as a forage source for livestock. About one-third is the dry matter of the sunflower plant, so large amounts of potential forage are not used when grown for seed only. Stressed or low-yielding sunflowers can be profitable if used as a forage source for livestock. As a suitable alternative in drought conditions, sunflower forage is usually fed as silage and can be a valuable option.
Fodder silage machine is a device used to prepare and store green fodder.
Silage corn is harvested before seed corn and in the milky-waxy stage (this is when the plant has 70-75% water and by ensiling it, good quality fodder is obtained). It is better to harvest silage corn that is close to The waxy stage should be done depending on the means of harvest. It should be remembered that it takes about 10 days from the end of the milky stage to the waxy stage. (when the cobs have more than 40% of dry matter) in this stage (milky to waxy stage) the digestibility coefficient of organic matter for the whole plant is almost constant.
Packaged silage can have variable nutrients depending on what kind of edible material it is made from, but what is used the most in Iran is corn silage.
The quality of corn fodder is unique in feeding dairy cows. This plant has a high nutritional value and contains large amounts of energy and starch.
Different management methods used for corn silage can affect the quality and quantity of its nutrients.
It is a machine which rolls ready silage, beet pulp, fruit pulp and various green forage plants which are filled in feeding bunker with dumper truck by pressing them in bales.
Combined silage roll baler which is produced by KOMEL company, is driven by tractor shaft (PTO) system and electric motor.
The packing operation should be done when the moisture content of the fodder is reduced to twenty percent. If the fodder is packed with high humidity, and due to the increase in the pressure of the density unit, it is possible to cut the shear pin or operate the friction clutch, the fodder will quickly mold after packaging.
