![]() ![]() Furthermore, use of the HOB film, which ensures a longer shelf life of silage during consumption, reduced the detrimental effect of yeasts, molds, and aerobic and anaerobic spore-formers on the nutritional and microbiological quality of the unloaded silage.Īerobic deterioration corn silage dry matter loss oxygen barrier film.Ĭopyright © 2014 American Dairy Science Association. This led to a net economic gain when the HOB film was used on both farms due to the increased DM recovery and reduced labor time required to clean the upper layer, even though the HOB film cost about 2.3 times more than the PE film. The use of the HOB film prevented almost all of the silage in the upper layer from spoiling only 2 out of 32 samples had a mold count >6log10 cfu/g. The top layer of silage conserved under the HOB film had a higher lactic acid content and lower pH lower counts of yeasts, molds, and aerobic and anaerobic spore-formers higher aerobic stability and lower DM losses than the silage conserved under the PE film. We also determined the economic benefit of applying the novel covering. During spring-summer consumption, the bags were unloaded, weighed, and subsampled to analyze the dry matter (DM) content, neutral detergent fiber and starch contents, pH, lactic and monocarboxylic acids, yeast and mold counts, aerobic and anaerobic spore-former counts, and aerobic stability. ![]() Plastic net bags with fresh chopped corn were buried in the upper layer (close to and far from the wall) and in the central part of the bunkers. Two bunkers (farms 1 and 2) were divided into 2 parts lengthwise so that half of the silo would be covered with PE film and the other with HOB film. This is also used as feed for livestock, often dairy cattle. In 2010 alone, 26 Americans were killed in silo accidents. Silos are used to store silage, which is whole corn stalks that have been harvested partially green and blown into tall tubes that keep the air out and allow the corn, leaves, stems, ears and all to go through a fermentation process, kind of like making Saur kraut. Accidents happen, and they’re often fatal. RF 2AK01XR Corn storage inside a house in Kampong Cham, Cambodia.

The enormous grain bins that dot the Iowa landscape store enough dried corn to swallow a body completely, squeezing the breath and life from a person in seconds. Image shows five new silos glowing in the sun with a field of corn in the foreground. This study examined the effect on the fermentation, chemical, and microbiological quality of corn silage covered with a new-generation high oxygen barrier film (HOB) made with a special grade of ethylene-vinyl alcohol (EVOH) compared with a standard polyethylene film (PE). He was alone in the stifling darkness, being slowly crushed to death. ![]()
