Nutritive value of corn silage

Corn is one of the forages which is often used as silage and fed to ruminant animals. The good quality corn silage contains high energy and protein (average 8.1%). The keys for producing good quality corn silage are to ensure that corn is harvested at proper moisture content approximately 65% - 70%, filled rapidly and packaged well. The objective of this study is to determine the nutritive value of silage produced from grain corn. The corn was planted on April 2017 at Malaysia Veterinary Institute, Kluang Johor. It was harvested using corn harvester at 75 days after planting. The chopped corn was placed in a 9 tonnes capacity bunker; it was piled in a large heap and compressed using skid steer loader to purge as much oxygen as possible, then it was covered with a heavy plastic sheet and old tires. Fresh corn and 30 days ensilage corn was sent to a laboratory for proximate analysis. Dry matter (DM) of fresh corn is 32.2% with 9.6% crude protein (CP) and 10.67MJ/kg metabolism energy (ME). Meanwhile, the nutritive value of ensilage corn which is DM, CP and ME are 30.6%, 8.5%, and 10.14MJ/kg respectively, with TDN value 67%. The results also showed that pH of ensilage corn is 3.7 which is perfect pH for silage (range pH is 3.5 – 4.2). All nutrient contents of corn silage are slightly reduced compared to fresh corn but still preserved the values for animal’s requirement and in the desirable range of target values.
