Comments Of The Ensiling Process In looking at the normal ensil ing process, there are a number of related points that should be kept in mind. 12. Temperature. The develop ment of warm silage during the ensiling process is not necessary for the production of quality sil age, although so-called "cold stor age" with high moisture hay crops may suggest clostridia-type activi ty. The best temperature for lacto bacilli is in the 2S-30 degrees C range (75-90 degrees F). 13. Heat Buildup. Air is nor mally required for any appreciable heating to occur. Heat is the result of plant respiration and the by product .of microbial activity.

Heating causes a darkening of color or "browning" effect, in which parts of the silage protein (amino acids) are bonded chemi cally to the soluble sugars, form ing a brown, lignin-like material which is indigestible to animals. Thus, heating causes a protein tie up, thereby lowering the digesti bility of the silage. This problem is the greatest in low moisture sil ages which are less dense and more open to continued air infilt ration. The degree of tie-up is dependent on the temperature reached and the length of the heat ing period. Of course, in addition to this type of loss, the fact that heating occurs means energy (dry REVENGER RV WHITEWALL >lB5/70R14 882 >2OB/70R14 865.01 >215/70R14 687.01 ’215/70R15 ’5/70R15 872.01 15/70R15 678.01 ’28570R15 BLACKWALL 1649.51 '175/70R13 1651.01 JIBS/70R13 IBaa.ool ■l9B/70R14 $48.00 ■ISS/BORI3 $48.00 PlB5/BORI3 M75/BORI3 $Bl.OO ■IBS/80R13 $82.00 ■lBB/7SRI4 $BB.OO '195/75R14 sBB.oi 18/78R14 $B2. ■215/7SRI4 $B7. iRIS $84.01 ■215/78R1S $66, [2S/7SRIS $BB.

Silo Fins. If the aerobic conditions for a sufficient length of time, the temperature of the ensiling mass will continue to rise to the point where, under certain conditions, spontaneous combus tion will occur. This type of prob lem is most apt to occur with whole-plant silages in the 24-45% moisture content range stored in a non oxygen-limiting environment. Silo fires, although most prevalent in conventional, top-unloading silos, also occur in controlled atmosphere silos which are not maintained properly (i.e. develop air leaks). IS. Silage Additives.

However, under some conditions, there may be an advantage in the addition of either selected strains of lactobacillus or enzymes that aid the growth of existing acid producers. 16. Acid Production. The mois ture content of ensiling matter plays a large part in the fermenta tion process. In addition to its direct effect on air exclusion (influences silage density), it also affects acid production. Bacterial activity is lower in low moisture material, resulting in incomplete fermentation (higher pH). This reduces the protection of the sil age from spoilage organisms. On the other hand, with high moisture content material, a greater amount of acid is required, since the acid is diluted by the contained water. This may add to the fermentation problem with some plant material such as alfalfa, which already has a low sugar content, so necessary for acid production. 17. Seepage. In the extreme, where silage seepage occurs, this material, although relatively low in nutritional value, still contains the most soluble portion of the plant material. The WSC lost results in a reduced level of readi ly available sugars for fermenta tion. Seepage is caused: a) by the pressure of overlay material and b) as a by-product of the initial (aerobic) phase as a result of the Prlci 6 62. 9 eg. $ $ 72. $lO9. $ 91-01 $ 95.0( $ 87.01 EARLY ORDER SUPER SALE 6 SUPER SALE! 56” CEILING FANS CFM’s 20,S0()_* A Single Speed Reg. $99.99 sale $59.99 pleabantaireW STANDARD FANS fans /m " m 12” Single. $149.99 ■ 14” Single. $159.99 Jl 18” Single. $179.99 ijnmP' 24" Single. $219.99 Variable.. ...$189.99 Variable Not Available Variable $239.99 /ljT\ Varnblc $289.99 \Vy Prlei 633.01 634. 1635.01 636.01 641.0< 643.01 640.01 $39.0! $40.0! $43.01 $48.01 $47.

The opti mum moisture content range for efficient fermentation is 55-65%. Within silo losses (open silos) are the least at the same moisture con tent range. 18. Proteolysis. One of the actions which occurs during the ensiling of forage is a degradation process called proteolysis. This is a process which results in the con version of protein present in fresh herbage to various non-protein nitrogen (NPN) constituents. Many NPN compounds are'highly water soluble and are poorly util ized in the rumen of cattle. There is extensive absorption of these compounds through ■ the rumen wall and subsequent excretion by the animal. It is highly desirable, from a nutritional standpoint, that protein not be degraded and made water-soluble in the rumen, but pass through to be utilized in the lower intestine. Proteolysis in sil age is the result of the activity of plant enzymes called proteases and various micro-organisms. This process becomes quite rapid once the crop is cut. The rate of proteolysis is affected by forage species (higher in legumes), silage moisture content, pH, and temper ature (all less at lower values). Reduction in silage quality because of proteolysis can, to a large degree, be prevented by fol lowing good ensiling and silo management principles.
