Using The Red Clover Polyphenol Oxidase Gene To Inhibit Proteolytic Activity In Lucerne, R. D. Hatfield, M. L. Sullivan, R. E. Muck

IGC Proceedings (1977-2023)

Preserving high quality forage in cool humid regions of agricultural production remains a challenge due to potentially high levels of protein degradation during ensiling. Red clover is an exception maintaining its high protein levels during ensiling. Decreased proteolytic activity in red clover is due to polyphenol oxidase (PPO) activity and appropriate o-diphenol substrates (Jones et al., 1995, Sullivan et al., 2004). This work highlights potential strategies for utilising PPO as a means of decreasing proteolytic degradation during the ensiling of lucerne and other forages.

New Results On Inhibition Of Clostridia Development In Silages, E. Kaiser, K. Weiß, I. Polip

IGC Proceedings (1977-2023)

The prevention of clostridial activity in silages is one of the most important aims in silage making. Clostridial activity in silages is especially expressed as the occurrence of butyric acid and as increased content of clostridial spores. A rapid reduction in the pH value at the beginning of fermentation process is considered as the most important factor for inhibition of clostridial development. It is assumed, that, if the “critical pH value” will be quickly achieved, clostridial activity in silages can be stopped. In experiments concerning the fermentation process it was found that the effect of acidification and dry matter content …

Ensilability And Silage Quality Of Different Cocksfoot Varieties, U. Wyss

IGC Proceedings (1977-2023)

Various factors determine the ensilability of plant crops. In addition to dry matter content, sugar and protein content, buffering capacity, plant structure, soil contaminations and epiphytic microflora are also important. In Switzerland, various mixtures and also pure swards are continuously revised on the basis of results from variety testing programs. The main parameters for these tests are the yield and nutrient contents. However, in terms of ensilability and silage quality, no systematic tests have been carried out. For this reason, we have tested the ensilability of different cocksfoot varieties as well as the quality of the silages.

Effects Of Silage Preparation And Microbial Silage Additives On Biogas Production From Whole Crop Maize Silage, M. Neureiter, C. Perez Lopez, H. Pichler, R. Kirchmayr, R. Braun

IGC Proceedings (1977-2023)

Biogas applications based on the production of energy from renewable resources have emerged in the past years due to several countries setting quotas for bioenergy thus promoting anaerobic digestion for heat and electricity generation. Maize is one of the most common substrates for biogas production based on energy crops because of the high yields per hectare with ensiling as the preferred method for storage. Experiments were performed to investigate whether conditions during the silage fermentation and the addition of starter cultures can affect the biogas yields.

Ensiling Characteristics Of Sudangrass Silage Treated With Green Tea Leaf Waste Or Green Tea Polyphenols, M. Kondo, K. Kita, H. Yokota

IGC Proceedings (1977-2023)

Green tea waste (GTW), emitted from beverage companies manufacturing tea drinks, contains high crude protein (CP) and polyphenols. Kondo et al. (2004) showed that GTW addition to forage ensiling enhanced lactic acid fermentation and decreased pH value. Ishihara et al. (2001) showed that high counts of Lactobacillus species were maintained and the counts of clostridia were decreased in the intestinal microflora of animals fed the diet containing green tea polyphenols (GTP). It is hypothesised that GTP might activate lactic acid bacteria and enhance silage fermentation. This study was conducted to evaluate the potential of GTW and GTP as silage …

A 16s Rdna-Based Quantitative Assay For Monitoring Lactobacillus Plantarum In Silage, M. Klocke, K. Mundt, C. Idler, P. O'Kiely, S. Barth

IGC Proceedings (1977-2023)

Ensilage of herbaceous biomass can be enhanced by applying pre-selected fermentative bacteria, however insufficient is known about the population dynamics of such starter cultures under a range of ensiling conditions. Classical methods for species-specific quantification of bacteria are labour intensive. An alternative approach is the detection of bacteria based on molecular markers for species-specific regions within their genomic DNA (e.g. the 16S rDNA sequence). In this study, a quantitative marker assay using the real-time PCR technique (Q-PCR) is described for Lactobacillus plantarum, a bacterium often used for silage starter cultures.

A Comparison Of The Efficacy Of An Ultra-Low Volume Applicator For Liquid-Applied Silage Inoculants With That Of A Conventional Applicator, G. Marley, G. Pahlow, H. -H. Herrmann, T. R. Owen

IGC Proceedings (1977-2023)

Liquid-applied silage inoculants are normally sprayed onto forages cut for ensiling at application rates from 1 to 3 l/t. Applicator tanks can require frequent re-filling, especially with large self-propelled forage harvesters having harvest rates in excess of 1000 t/d. This can be an issue for fields remote from the farm, for areas with restricted water availability and for contractors paid by the area harvested. This study was conducted to assess the efficacy of inoculant distribution on the crop using a simple, ultra-low volume (ULV) applicator compared with a conventional liquid-applied silage inoculant applicator.

Improving The Aerobic Stability Of Whole-Crop Cereal Silages, I. Filya, E. Sucu, A. Karabulut

IGC Proceedings (1977-2023)

Whole-crop cereal silages, such as wheat, sorghum, and maize are susceptible to aerobic deterioration, especially in warm climates. This is because aerobic yeasts are the most active at 20-30°C (Ashbell et al., 2002). Therefore, it is very important to find suitable additives that inhibit fungi and protect the silage upon aerobic exposure. Propionibacterium acidipropionici is propionic acid bacteria (PAB), which produce propionic and acetic acid in silage. Results with these micro-organisms in laboratory studies were promising with regard to aerobic stability. The purpose of the present work was to study the effects of PAB, lactic acid bacteria (LAB) and …

Microbial Changes And Aerobic Stability In High Moisture Maize Silages Inoculated With Lactobacillus Buchneri, R. A. Reis, E. O. Almeida, G. R. Siqueira, T. F. Bernardes, E R. Janusckiewicz, M. T. P. Roth

IGC Proceedings (1977-2023)

Oxygen exposure changes microbial and chemical profiles of silages after silo opening. Yeast and fungi are the main active microorganisms responsible by consumption of nutrients and fermentative residual products, which increases temperature in the ensilaged mass. The Lactobacillus buchneri (L. buchneri) has been considered an aerobic stability controller. This work aimed to evaluate the effect of L. buchneri in ensilage process of high moisture maize.

Aerobic Stability And Nutritive Value Of Low Dry Matter Maize Silage Treated With A Formic Acid-Based Preservative, I. Filya, E. Sucu, A. Karabulut

IGC Proceedings (1977-2023)

Aerobic stability is one of the major problems of the ensiling process, especially in warm climates. Ashbell et al. (2002) have shown that at 30°C, the development of aerobic yeast and moulds in silages is most intensive. In Turkey all silages are susceptible to air penetration during storage and unloading with a large proportion of the silage spoiled and in extreme cases all the silage is spoiled. The purpose of the present work was to study the effects of formic acid-based preservative (FAB; Kemisile® 2000, Kemira Oyj-Industrial Chemicals, Finland) on the aerobic stability and nutritive value of maize silage.

An In Vitro Study On The Influence Of Residual Sugars On Aerobic Changes In Grass Silages, S. D. Martens, G. Pahlow, J. M. Greef

IGC Proceedings (1977-2023)

The Effects Of The Growth Stage And Inoculant On Fermentation And Aerobic Stability Of Whole-Plant Grain Sorghum Silage, E. Tabacco, G. Borreani

IGC Proceedings (1977-2023)

Grain sorghum (Sorghum bicolor) is well adapted to environments with limited rainfall and low soil fertility. Today, on dry land, improved grain sorghum hybrids may be a valid alternative to maize silage and they may give DM yields and digestible energy that are comparable to maize, but at lower production costs (Legarto, 2000). Harvesting crops for silage at an early stage of maturity (low DM content) may result in silage with a higher acid content and low nutritional quality, while harvesting crops at a later stage of maturity may make the forage more difficult to chop and pack. …

Perennial Ryegrasses Bred For Contrasting Sugar Contents: Manipulating Fermentation And Aerobic Stability Using Wilting And Additives (1) (Eu Fp V -Project ‘Sweetgrass’), P. O'Kiely, H. Howard, G. Pahlow, R. J. Merry, F. P. O'Mara

IGC Proceedings (1977-2023)

Higher concentrations of water-soluble carbohydrate (WSC) in silage offer ruminant nutrition and environmental attractions. Both successful field wilting and alternative silage additives provide the opportunity to manipulate silage WSC by modifying fermentation and/or improving aerobic stability. This experiment evaluated the fermentation and aerobic stability of silages made from perennial ryegrass cultivars of high or normal WSC genotype that differed in field wilting or additive use.

Perennial Ryegrasses Bred For Contrasting Sugar Contents: Manipulating Fermentation And Aerobic Stability Of Unwilted Silage Using Additives (2) (Eu-Project ‘Sweetgrass’), H. Howard, P. O'Kiely, G. Pahlow, F. P. O'Mara

IGC Proceedings (1977-2023)

Grass cultivars bred for elevated concentrations of water-soluble carbohydrate (WSC) could have improved silage preservation but possibly disimproved aerobic stability. Additives can be used to manipulate fermentation and thereby increase silage WSC. They can also influence aerobic stability. This experiment evaluated the fermentation and aerobic stability of unwilted silages made from perennial ryegrass cultivars of high or normal WSC genotype that differed in additive use.

Perennial Ryegrasses Bred For Contrasting Sugar Contents: Manipulating Fermentation And Aerobic Stability Of Wilted Silage Using Additives (3) (Eu-Project ‘Sweetgrass’), H. Howard, P. O'Kiely, G. Pahlow, F. P. O'Mara

IGC Proceedings (1977-2023)

Rapid field-drying of grass prior to successful ensilage restricts fermentation and can assist preservation, but can consequently result in silages that are prone to aerobic deterioration at feedout. Additives that directly (e.g. potassium sorbate or sodium benzoate) or indirectly (e.g. formic acid or Lactobacillus plantarum, via manipulation of fermentation) alter yeast activity at feedout could modify silage aerobic stability. This experiment evaluated the fermentation and aerobic stability of wilted silages made from perennial ryegrass cultivars of high or normal water soluble carbohydrate (WSC) genotype that differed in additive use.

The Effect Of Additive Containing Formic Acid On Quality And Aerobic Stability Of Silages Made Of Endophyte-Infected Green Forage, L. Podkówka, J. Mikołajczak, E. Staszak, P. Dorszewski

IGC Proceedings (1977-2023)

Festuca species grasses are very often infected with endophytic fungi Neothypodium, that produce ergotic alkaloids, peramins etc. (Podkówka et al., 2003). Produced green forage can be dangerous to animals. The basic preservation method of such green forages is ensiling, especially with organic acids addition. Organic acids demonstrate destructive action on fungal organisms, as well as influence the quality and aerobic stability of forage. The objective of this study was to determine if the preservation of endophyte-infected green forage by ensiling with formic acid affects quality and aerobic stability of produced fodder.
