Some factors affecting on nutritive value of whole plant corn silage

Abstract |
In Egypt, the total planted area of com crop was about 1 million feddans (420,000 hectare), but only 140 thousand feddans cultivated with yellow com hybrids, the area of com crop used as a silage was about 250 thousand feddans (National Campaign of Com Crop Rising, 2007). Whole plant com silage is a popular forage source for ruminants due to its high yielding properties, energy content, relatively high palatability and incorporating easily into TMR (Cherney et al., 2004). Recently, agronomists, nutritionists, and dairy producers have placed increased emphasis on factors effecting the nutritive value of whole plant com silage (Bal et al., 2000).
Com hybrids with high stay-green rankings were found to have higher moisture and protein concentrations and lower starch content than average stay-green hybrids, but the fermentation process was unaffected by stay-green ranking. Stay-green hybrids should be harvested at about 34% DM (66% moisture) as this maturity stage gave the best combination of yield, nutritive value and low fungal counts. Due to the higher moisture content of high stay-green hybrids, they should not be harvested at DM concentrations below 30% particularly during rainfall or in wet years because excess moisture can cause undesirable fermentations (Adesogan, 2006).
The present investigation was undertaken to study the effect of hybrid type, cultivation season, stage of maturity and plant density on yield, fermentation characteristics, chemical composition, nutrients digestion, nutritive values and nutrients yields of whole com plant silage.
