Fermentation, losses, and aerobic stability of sugarcane silages treated with chemical or bacterial additives

Association of Biological and Chemical Additives on Nutrient Composition, Total Losses, Microbiological and Fermentative Profile of Sugarcane Silage

The aim of this study was to determine the effects of a bacterial inoculant and chemical additives on nutrient composition, in vitro degradation, total loss, aerobic stability, microbiological quality, and fermentative profile of sugarcane silage. Treatments were distributed to forty-eight mini-silos in a 2 × 4 factorial arrangement: two levels of microbial inoculant (INO, 0 or 4 g/t of fresh s...

Improving the aerobic stability of silages

Improving the aerobic stability of silages M ICRO-ORGANISMS involved in the ensiling process include beneficial bacteria (homolactic acid bacteria), detrimental bacteria (for example, clostridia) and unwanted yeasts and moulds. In a good silage pit (or bun), air is eliminated by respiration from the plant and packing, thus preventing the growth of detrimental aerobic microbes. When air is elimi...

The Effects of Additives in Napier Grass Silages on Chemical Composition, Feed Intake, Nutrient Digestibility and Rumen Fermentation

The effect of silage additives on ensiling characteristics and nutritive value of Napier grass (Pennisetum purpureum) silages was studied. Napier grass silages were made with no additive, fermented juice of epiphytic lactic acid bacteria (FJLB), molasses or cassava meal. The ensiling characteristics were determined by ensiling Napier grass silages in airtight plastic pouches for 2, 4, 7, 14, 21...

Aerobic Spoilage of Silages

The effect of a surface open to air on the ensiling process was investigated in 15 × 60 cm PVC silos in four trials, three with alfalfa (30, 41, and 49% dry matter, DM) and one with whole-plant corn (35% DM). Silos were sampled 1, 2, 5, 7, 14, and 28 d post-filling at 5, 20, 35, and 50 cm from the open surface. At 5 cm, little fermentation occurred as oxygen contents were at 10% or higher, and ...
