“…This study further revealed that the addition of whey and molasses increased (P <0.05) the concentration of lactic acid, reduced silage pH and the concentrations of butyric acid and NH 3 -N compared to the UPHS, indicative of wellpreserved silages (McDonald et al, 1991). This result agrees well with previous work that reported higher lactic acid concentrations, lower pH and NH 3 -N concentration when molasses (Bolsen et al, 1996;Yunus et al, 2000) and whey (Zobell et al, 2004;Bautista-Trujillo et al, 2009,) were added to a forage at ensiling compared to the control. Moreover, whey and molasses addition reduced (P <0.05) the fibre content of the silage as compared to MS and UPHS.…”

“…The silages in the present study had NH 3 -N concentrations of less than 100 g NH 3 -N/kg TN. However, treating potato hash silage at ensiling with either whey or molasses further reduced (P <0.05) the NH 3 -N concentration compared to the UPHS, confirming the work of other researchers (Yunus et al, 2000;Bautista-Trujillo et al, 2009;Nkosi et al, 2009) who found reduced NH 3 -N production. This could be explained by the fact that whey and molasses reduced the pH, resulting in a decreased production of NH 3 -N in the silage compared to the UPHS.…”

“…They are costly to the farmer and their effectiveness can be less reliable, since it is based on the activity of living organisms (Weinberg & Muck, 1996). Alternatively, food waste materials such as whey (Nkosi, 2003;Zobell et al, 2004;Bautista-Trujillo et al, 2009) and sugarcane molasses (Bolsen et al, 1996;Yunus et al, 2000;Van Niekerk et al, 2007;Nkosi et al, 2009) can be used as silage additives to ensile high moisture potato hash. The present study compared the fermentation characteristics of potato hash silage produced without or with additives (whey and molasses) with that of maize silage.…”

________________________________________________________________________________ AbstractThe aim of the study was to determine the effect of whey or molasses on the fermentation quality when added to potato hash silage. In addition, lamb performance, digestibility and feed intake of diets containing potato hash silage were compared with a diet containing maize silage (MSd). Potato hash silage (treated with no additive, or whey, or molasses) and MS were produced in 210 L drums for 90 days and the fermentation quality of the silages was determined thereafter. Diets were formulated and fed ad libitum to 32 South African Dorper lambs (23.5 ± 0.873 kg live weight) for 63 days. A digestibility study was conducted during the last week of the study. The untreated potato hash silage (UPHS) was poorly fermented as indicated by higher concentrations of butyric acid, ammonia-N and pH compared to the other silages. Higher dry matter intake (DMI) and daily weight gains (218 and 250 g/d) were obtained with MSd and molasses treated potato hash silage diet (MPHSd) compared to the other diets. Nutrient digestibility was lower in the UPHS diet compared to the other dietary treatments. It was concluded that the fermentation quality of potato hash was improved with the addition of whey and molasses. Furthermore, growth performance was higher with the MSd and MPHSd than of the other treatments, suggesting that MPHSd can safely replace MSd in a lamb diet at a dietary inclusion level of 20% without any adverse effect on animal performance. ________________________________________________________________________________

“…Selain itu juga Dass et al (2001) menyatakan bahwa penambahan asam pada amoniasi jerami padi terbukti dapat menangkap amonia yang terlepas sebesar 30 persen. Yunus et al (2000) menyatakan bahwa penambahan molases pada silase Clover-grass berfungsi untuk meningkatkan produksi asam laktat dan menurunkan asetat dan juga amonia-N. Peningkatan kecernaan amoniasi jerami padi yang ditambahkan dengan molases disebabkan karena molases digunakan sebagai sumber energy untuk berkembangbiakan bakteri rumen sehingga mampu memanfaatkan NH 3 . Selain itu suasana asam tersebut mampu merenggangkan ikatan-ikatan serat yang ada pada jerami padi, sehingga mikroba rumen mampu menghidrolisis dan memfermentasi selulosa, hemiselulosa dan karbohidrat lainnya yang ada pada jerami tersebut.…”

Aimed of this research was to find out the optimal level of molasses addition to improve quality, dry matter and organic matter digestibility of rice straw ammonization process. Materials used were rumen fluid of fistula cattle, grind of rice straw, water, urea and molasses. Research designed used Completely Randomized Design (CRD). As treatments were R0: rice straw 1000 g dry matter + 500 g water + 50 g urea + 0 percent of molasses, R1: R0 + 15 percent of molasses, R2: R0 + 30 percent of molasses. Urea and molasses dissolved in water and then entered into pollybag. All pollybag observe and let for 15 days, each treatment replicated 6 times. Variable measured were dry matter digestibility and organic matter digestibility. Research result showed that ammonization product of NH 3 , Acidity Level and crude fiber having decreased while crude protein content increased. Variance analysis indicated that treatments had significant effect (P<0.05) on dry matter and organic matter digestibility. Orthogonal polynomial test indicated that level of molasses increase (P<0.05) of dry matter and organic matter digestibility linearly. It can be concluded that addition up to 30 percent in ammoniating of rice straw using urea can improve quality of ammonization and increasing dry matter and organic matter digestibility.

“…The silage produced from normal-type napiergrass produced lactic acid as a primary fermentation product [3,4], especially when the addition of a saccharide such as glucose was added during fermentation [5,6]. Normal-type napiergrass ensiled with corn [7], molasses [8][9][10][11], formic acid [6], and ethanol [12] as additives would produce good-quality lactic-type silage.…”

Fermentation Quality of Round-Bale Silage as Affected by Additives and Ensiling Seasons in Dwarf Napiergrass (Pennisetum purpureum Schumach)

Fermentation quality of dwarf napiergrass (Pennisetum purpureum Schumach) was estimated for additives lactic acid bacteria and Acremonium cellulase (LAB + AC), fermented juice of epiphytic lactic acid bacteria (FJLB), and a no-additive control in 2006 via two ensiling methods-round-bale and vinyl-bag methods in 2006-and via two ensiling seasons-summer and autumn of 2013. Fermentation quality of dwarf napiergrass ensiled in the summer season was improved by the input of additives, with the highest quality in LAB + AC, followed by FJLB; the lactic acid content was higher, and the pH and sum of the butyric, caproic, and valeric acid contents were lower, resulting in an increase in the V-score value by each additive. The ensiling method in autumn without additives affected fermentation quality, mainly due to the airtightness, which was higher for round-bale processing than in vinyl bags, even with the satisfactory V-score of 72. Fermentation in round bales without additives had a higher quality in autumn than in summer, possibly due to the higher concentration of mono-and oligo-saccharides. Thus, it was concluded that dwarf napiergrass can be produced to satisfactory-quality silage by adding LAB + AC or FJLB in summer and even in the absence of additives in autumn.
