“…The soluble fraction (a) of silage, which comprises a combination of preserved material of the original forage and fermentation end products, had higher values for soybeanenriched and urea-enriched silages (Table 2). This corroborates with Diaz et al (2013) who observed the addition of ammonia improved the soluble carbohydrates accumulation in the silage.…”

Because of the high total digestible nutrient and dry matter (DM) digestibility contents , high moisture silage may be an alternative to maximize animal performance. Thus, the objective of this study was to evaluate the chemical composition, ruminal degradability and aerobic stability of high moisture corn silage (pure corn grain silage and soybean-, sunflower-or urea-enriched silages). Plastic barrels with capacity of 200 kg were used as experimental silos, which remained closed for nine months. The experimental design was completely randomized with four replications. After opening the silos, the chemical-bromatological composition and the quality of silages were determined. The addition of soybean or sunflower increased the crude protein content (CP) in 48.2% on average, and the neutral detergent fiber content in 60%, but decreased the starch content when compared to pure high moisture corn silage. Moreover, additions decreased the effective DM and CP degradability. Addition of urea decreased by 30% DM losses and improved the chemical composition and aerobic stability of the silage. In general, additives improved the chemical composition without affecting the silage conservation quality.

“…Entretanto, com um tempo maior de incubação (48 horas) nas análises de digestibilidade in vitro não foi verificada diferença (P>0,5) entre as silagens avaliadas, com valores de DIVMS de 96% para SGMS, SGMSI e SGMSU. Diaz et al (2013) também não verificaram diferenças para digestibilidade de bovinos alimentados com silagem de grãos úmidos com a utilização de bactérias homo ou heterolaticas ou utilização de amonia.

Objetivou-se avaliar o efeito do uso de aditivo microbiano e de uréia na composição química, digestibilidade in vitro, no desaparecimento ruminal, e na estabilidade aeróbia de silagens de grãos úmidos de milho com adição de soja crua. Um segundo ensaio foi conduzido com o objetivo de avaliar a substituição do concentrado comercial por silagem de grãos de milho com adição de 20% de soja crua na produção e composição do leite de vacas holandesas. Para a avaliação das silagens foram feitos mini silos de pvc arranjados em delineamento inteiramente casualizado com três tratamentos (silagem de grãos úmidos de milho + 20% de soja crua; silagem de grãos úmidos de milho + 20% de soja crua + inoculante microbiano e silagem de grãos úmidos de milho + 20% de soja crua + 1,4% de ureia) e quatro repetições. As silagens apresentaram-se estáveis no período de 96 horas, com perdas de matéria seca de 3,55, 3,32 e 4,39 para silagens sem aditivos, com a adição de inoculante microbiano e com uréia respectivamente. A adição de uréia diminuiu a taxa de degradação ruminal das silagens de grãos úmidos de milho com adição de soja. Para a avaliação da produção e composição do leite foram utilizadas 20 vacas leiteiras arranjadas em delineamento inteiramente casualizado, com dois tratamentos e dez repetições. Verificouse que a silagem de grãos de milho com adição de grãos de soja pode ser usada na alimentação de vacas em lactação sem impacto sobre a produção e composição química do leite, mantendo os níveis de produção.

“…In a dairy cow experiment, where ammonium propionate at 5 L/t was applied to corn silage, no effect on intake or milk yield was observed (Levital et al, 2009). Furthermore, Diaz et al (2013) found no improvements in diet digestibility, N balance, LWG, or carcass quality of finishing steers fed ammoniated or untreated high-moisture ear corn. However, compared with untreated silage, Nadeau and Arnesson (2016) reported increased live weight at birth (6.0 vs. 5.2 kg) and a tendency for increased LWG until weaning (442 vs. 409 g/d) in lambs suckling ewes fed grass-clover silage treated with an additive, containing sodium nitrite, hexamine, sodium benzoate, potassium sorbate, and sodium propionate applied at 2 L/t.…”

Additives have been available for enhancing silage preservation for decades. This review covers research studies published since 2000 that have investigated the efficacy of silage additives. The review has been divided into 6 categories of additives: homofermentative lactic acid bacteria (LAB), obligate heterofermentative LAB, combination inoculants containing obligate heterofermentative LAB plus homofermentative LAB, other inoculants, chemicals, and enzymes. The homofermentative LAB rapidly decrease pH and increase lactic acid relative to other fermentation products, although a meta-analysis indicated no reduction in pH in corn, sorghum, and sugarcane silages relative to untreated silages. These additives resulted in higher milk production according to the meta-analysis by mechanisms that are still unclear. Lactobacillus buchneri is the dominant species used in obligate heterofermentative LAB silage additives. It slowly converts lactic acid to acetic acid and 1,2-propanediol during silo storage, improving aerobic stability while having no effect on animal productivity. Current research is focused on finding other species in the Lb. buchneri group capable of producing more rapid improvements in aerobic stability. Combination inoculants aim to provide the aerobic stability benefits of Lb. buchneri with the silage fermentation efficiency and animal productivity benefits of homofermentative LAB. Research indicates that these products are improving aerobic stability, but feeding studies are not yet sufficient to make conclusions about effects on animal performance. Novel non-LAB species have been studied as potential silage inoculants. Streptococcus bovis is a potential starter species within a homofermentative LAB inoculant. Propionibacterium and Bacillus species offer improved aerobic stability in some cases. Some yeast research has focused on inhibiting molds and other detrimental silage microorganisms, whereas other yeast research suggests that it may be possible to apply a direct-fed microbial strain at ensiling, have it survive ensiling, and multiply during feed out. Chemical additives traditionally have fallen in 2 groups. Formic acid causes direct acidification, suppressing clostridia and other undesired bacteria and improving protein preservation during ensiling. On the other hand, sorbic, benzoic, propionic, and acetic acids improve silage aerobic stability at feed out through direct inhibition of yeasts and molds. Current research has focused on various combinations of these chemicals to improve both aerobic stability and animal productivity. Enzyme additives have been added to forage primarily to breakdown plant cell walls at ensiling to improve silage fermentation by providing sugars for the LAB and to enhance the nutritive value of silage by increasing the digestibility of cell walls. Cellulase or hemicellulase mixtures have been more successful at the former than the latter. A new approach focused on Lb. buchneri producing ferulic acid esterase has also had mixed success in improving the efficiency of ...
