<b>Additive containing homo and heterolactic bacteria on the fermentation quality of maize silage</b> - doi: 10.4025/actascianimsci.v35i4.18833

Abstract

This trial evaluated the addition of <em>Lactobacillus plantarum</em>,<strong> </strong><em>L. brevis </em>and<em> Enterococcus faecium </em>combo additive against a control treatment. The silages were made in laboratory silos that were stored for 30, 60, 90 or 120 days before opening. We evaluated the chemical composition of the forage before and after ensiling and the fermentative losses of silages. The additive decreased (p < 0.01) effluent production (11.4 kg ton^-1) compared to control silage (14.0 kg ton^-1), but it increased (p < 0.01) the Neutral Detergent Fiber (NDF) and Acid Detergent Fiber (ADF) from 45.6% and 24.5% to 47.0 and 25.1% for control and additive silages, respectively. The storage periods affected (p < 0.01) effluent production, Dry Matter Losses (DML), NDF, ADF and pH variables. Fermentative losses were very low because of the adequate characteristics of maize for ensilage.<br /><p class="aresumo"><strong> </strong></p> <p class="akeyword"> </p><br /

A meta-analysis on the effectiveness of homofermentative and heterofermentative lactic acid bacteria for corn silage

“…Temel et al (2015) pointed that NDF and ADF are undesired structures in fodder crops. Degradation of cell wall content during fermentation may be considered positive to the process for providing soluble carbohydrates to fermentative micro-organisms and raising silage intake by animals (Junges et al 2013).…”

Yield and nutritive value of mechanically processed corn silage from an integrated crop-livestock system

“…Although they differed significantly among the treatments evaluated, the gas losses (mean 3.7% DM) were lower than those found in the literature. Junges, Schmidt, Novinski and Daniel (2013) compared the production of gases from corn silages with and without the use of inoculants and did not observe differences in the loss of gases between treatments, which made up an average of 4.5% DM. Excessive gas losses from silage occur under fermentation conditions due to undesirable microorganisms.…”

Dual sensor measurement shows that temperature outperforms pH as an early sign of aerobic deterioration in maize silage

“…2 cm) were air inlets for the aerobic-exposure measures when rubber stoppers were removed. Ex situ determination of silage pH followed a standard protocol of extraction of 25 g of maize silage with 0.225 L deionized water for 30 min 4 , 14 , 23 .…”

“…Since utilization of acids by aerobic microorganisms leads to a rise of silage pH, the pH of a silage mass reflects the extent of aerobic deterioration 14 . Previous studies of aerobic responses of silage pH used laboratory mini-silos 7 , 15 – 18 and farm silos 5 , 10 , 19 – 23 , both with invasive sub-sampling followed by liquid extraction of silage samples. Such ex situ pH determination may interfere with silage conditions, including the anaerobic environment, and is typically completed at daily (or longer) time intervals, which obscures important short term dynamic changes.…”
