example 1

[0031]Silage was made with fresh cut sugar cane from plants that were approximately 12 months old. The sugar cane was manually harvested and chopped using a laboratory-type chopper (Pinheiro, model: PP-47) to an approximate length of 30 mm. 3 kg of the chopped material was mixed with the inoculants and conditioned in PVC plastic buckets (mini-silos, 10 cm in diameter and 60 cm in length), which were sealed with tight lids containing Bunsen valves for gas release. The material in the silo was compacted to a density of approximately 630±19.9 kg m-3. The mini-silos were stored at room temperature and analyzed after 61 days of storage, and three replicates were prepared for each silo.

[0032]Silage was produced using the Lactobacillus plantarum SIL 34 (L. plantarum are commonly used as silage inoculant) and the Lactobacillus hilgardii strains SIL 51 (CNCM I-4784 filed on Jun. 26, 2013) and SIL 52 (CNCM I-4785 filed on Jun. 26, 2013) as inoculants. The Lactobacillus plantarum and the Lacto...

Aerobic Stability of Corn Silages

[0048]Corn silage was produced in micro-silos as described in Example 1 using the Lactobacillus buchneri, NCIMB 40788 (U.S. Pat. No. 6,326,037 to Mann et al.), the Lactobacillus plantarum SIL 34 and the Lactobacillus hilgardii strains SIL 51 (CNCM I-4784 filed on Jun. 26, 2013) and SIL52 (CNCM I-4785 filed on Jun. 26, 2013) as inoculants. Silage without any inoculants was used as a control. The inoculants were cultured as described in Example 1.

[0049]After 90 d of ensiling, the mini-silos were opened, and samples of approximately 3 kg were removed from each mini-silo and placed in 5 kg plastic buckets to assess the aerobic stability. A data logger was inserted into the silage mass, at a depth of 10 cm, for 7 days. The ambient temperature was measured using a data logger located close to the buckets. The data on aerobic stability of silages are shown in Table 4

Abstract

There is provided a method for treating silage which includes adding to the silage a silage inoculant including a silage preserving effective amount of Lactobacillus hilgardii. The silage inoculant being effective to prevent or reduce aerobic spoilage.

Description

[0001]The present description relates to silage. More specifically to silage inoculants and method of use of silage inoculants for enhancing aerobic stability of silage.[0002]Silage is fermented, high-moisture forage to be fed to ruminants, such as cud-chewing animals like cattle and sheep. The silage is fermented and stored in a storage silo, a process called ensilage. Silage is most often made from grass or cereal crops, including ryegrass, alfalfa, fescue, corn (maize) or sorghum. Silage is made from the entire plant, or part of it. Silage can also be made from many other field crops, including sugar cane, and other names such as, for example oatlage for oats, haylage for alfalfa are sometimes used when this is done. Sometimes a mixture is used, such as oats and peas.[0003]The production of silage and the associated crop husbandry have over recent years developed to an extent that a number of different processes can be defined. These are: (i) the ensiling of young grass with part...
