Utilisation Of Whole-Crop Pea Silages Differing In Condensed Tannin Content As A Replacement For Soya Bean Meal In The Diet Of Dairy Cows, K. J. Hart, R. G. Wilkinson, L. A. Sinclair, J. A. Huntington
IGC Proceedings (1977-2023)
Adesogan et al. (2004), has demonstrated that ensiled pea wheat intercrops can reduce the amount of concentrate fed to dairy cows by 50% without affecting milk yield or composition. A limitation of forage peas for high yielding dairy cows is the low by-pass protein content, but it has been suggested by Broderick (1995), that feeding forages that contain low levels of condensed tannin can improve nitrogen utilisation. The objective of the current experiments was to evaluate the potential of whole-crop pea silage differing in condensed tannin content to replace soya bean meal in the diet of late lactation, pregnant …

Ensiled High Moisture Barley Or Dry Barley In The Grass Silage-Based Diet Of Dairy Cows, S. Jaakkola, E. Saarisalo, R. Kangasniemi
IGC Proceedings (1977-2023)
Ensiling high moisture grain is based on a procedure similar to ensiling grass. Soluble carbohydrates of grain are partly fermented into acids and some protein is degraded. Thus the nutritional quality is modified by the preservation method. Two trials were conducted to compare the effects of dry barley (DB) and ensiled barley (EB) in a total mixed ration (TMR) on feed intake and milk production of dairy cows.

Effects Of Species, Maturity And Additive On The Feed Quality Of Whole Crop Cereal Silage, E. Nadeau
IGC Proceedings (1977-2023)
Chemical composition of whole crop cereals differ among species and maturity stages. These chemical differences create variations in silage quality (Bergen et al., 1991). There is only limited information available on the effects of plant species and maturity on the use of additives for whole crop cereal silage. The objective of this experiment was to determine the effects of species, maturity, additive and their interactions on nutrient composition and fermentation characteristics of whole crop cereal silage.

Comparison Of Different Maize Hybrids Cultivated And Fermented With Or Without Sorghum, Sz. Orosz, Z. Bellus, Zs. Kelemen, E. Zerényi, J. Helembai
IGC Proceedings (1977-2023)
In Hungary our key forage crop is silage maize, however, the joint growing of maize and sorghum is increasingly important in arid regions. The reason is, that sorghum varieties tolerate well the various ecological stresses (drought). The joint growing of maize and sorghum varieties has several advantages and disadvantageous in respect of yields, safety of production, fermentability of the crop and nutrient content of the silage. The basis of realising the complementary qualities of the two crops and of the successful joint growing and preservation is the suitable pairing of hybrid varieties.

Utilisation Of Coffee Grounds For Total Mixed Ration Silage, C. Xu, Y. Cai, N. Hino, N. Yoshida, M. Ogawa
IGC Proceedings (1977-2023)
In the beverage industry, wastes from coffee grounds are of particular importance given their rapid increase in recent years. Although a small part is converted into raw compost material, wastes generated from tea grounds are generally incinerated. There is increasing demand for efficient use of by-products due to economic and environmental concerns. Approximately 200,000 t of coffee grounds are produced annually in Japan. These grounds usually have high protein, fat, fibre, and nitrogen-free extract and possibly could be a source of nutrients for ruminant (Xu et al., 2004). The objectives of this study were to evaluate the fermentation characteristics …

Forage Preferences Of Horses, C. E. Müller
IGC Proceedings (1977-2023)
In the northern climates the forage fed to horses has by tradition been hay. However, hay is subjected to moulding unless it is stored dry. Mould spores together with actinomycetes are responsible for the condition Recurrent Airway Obstruction (RAO), which is the second largest reason for culling of warm-blood horses in Sweden (Wallin, 2001). Therefore, the possibility of replacing hay with haylage and silage in the feed rations of horses is interesting. The objective of this study was to investigate the preferences among horses for different types of conserved grass, to gain more knowledge about the suitability of haylage and …

The Effect Of Silage Harvester Type On Harvesting Efficiency, J. P. Frost, R. C. Binnie
IGC Proceedings (1977-2023)
Choice of harvesting system can significantly influence production costs. Whether a tractor-powered or self-propelled forage harvester or a self-loading forage wagon system is used will depend on particular circumstances. However, in order to make an informed choice relevant information has to be available. A trial was commissioned by Landmec Pottinger (Ivybridge, UK) and Traynors (Clonmel, Ireland) at this Institute to investigate the performance of a self-propelled forage harvester system and a self-loading forage wagon system.

The Effects Of A New Plastic Film On The Microbial And Fermentation Quality Of Italian Ryegrass Bale Silages, G. Borreani, E. Tabacco
IGC Proceedings (1977-2023)
Problems associated with big bale silage include the high permeability of plastic wrapping films to O2, their low resistance to damage and the large amount of plastic that must be used to limit aerobic deterioration during conservation. Low permeability film, used in the packaging of food and recently proposed for bunker silos (Degano, 1999), could reduce fungal development in bale silage. The aim of this work was to compare the microbial and fermentation quality of big-baled silage, wrapped with commercially available plastic film and a new stretch film with low O2 permeability, over different conservation periods.
The Effect Of Neutralising Formic Acid On Fermentation Of Fresh And Wilted Grass Silage,

The Effect Of Neutralising Formic Acid On Fermentation Of Fresh And Wilted Grass Silage, E. Saarisalo, S. Jaakkola
IGC Proceedings (1977-2023)
Rapid drop in pH is essential for minimising proteolysis and successful ensiling. Use of acid additives typically reduces protein degradation and restricts fermentation. The effects of acid additive depend on application rate and type of herbage. Corrosiveness and risks in handling formic acid (FA) can be reduced by using salts of FA like ammonium formate (AF). Increasing proportions of AF replacing FA were applied into grass at two dry matter (DM) contents to evaluate the effects of neutralised FA on silage pH and fermentation.

Influence Of Different Alfalfa-Grass Mixtures And The Use Of Additives On Nutritive Value And Fermentation Of Silage, P. Lättemäe, U. Tamm
IGC Proceedings (1977-2023)
Legumes have a high nutritive value but they are known to be difficult to ensile and often result in poorly fermented silage. This is usually due to high buffering capacity and low available sugar concentration. However, the results have shown that silage quality can considerably be improved by using additives or when legume-grass mixtures are ensiled (Lättemäe & Tamm, 2002). Different legume-grass mixtures differ in their ensiling properties and also may affect the fermentation. The objective of this experiment was to study the effect of alfalfa-grass mixtures and the use of additives on nutritive value and fermentation of silage.

Effects Of Inoculation Of Lab On Fermentation Pattern And Clostridia Spores In Easily Ensilable Grass Silages, J. Thaysen, G. Pahlow, E. Mathies
IGC Proceedings (1977-2023)
Clostridia can damage the protein quality of grass silages. They cause high gas losses during the fermentation process and quality problems in dairy products like semi-hard cheeses. In comparison to the effect of chemicals such as nitrite on undesirable clostridia in grass silages the respective inhibitory mechanism of LAB requires further investigation. The objective of this experiment was to study under laboratory conditions novel isolates of lactic acid bacteria (LAB), selected for their inhibitory effect on clostridia in grass silages.

IGC Proceedings (1977-2023)
Forage paddy rice is currently one of the most important silage crops in Japan. In fact, the use of paddy rice culture for silage production has been steadily increasing in recent years, not only because this represents a new way towards achieving self-sufficiency in animal feed, but also because of the interest of combining crop cultivation and livestock farming as a more effective use of idle paddy fields that often remain unused. However, the preparation of quality silage from paddy rice and its long-term storage are often challenging (Cai et al., 1999, 2003). In this study, a new bacterial …

Effects Of Stage Of Growth And Inoculation On Fermentation Quality Of Field Pea Silage, G. Borreani, L. Cavallarin, S. Antoniazzi, E. Tobacco
IGC Proceedings (1977-2023)
Field peas (Pisum sativum L.) are a short-term catch crop with a high crude protein content, which provides a high forage yield in a short growing period. Since field peas are a succulent crop and are difficult to field cure, it is preferable to directly ensile them to prevent weather damage and excessive grain losses. The onset of lodging is delayed in field pea varieties, since the crop is supported by the tendrils in a more erect manner, and this allows easy harvesting without soil contamination even at advanced stages of maturity (Koivisto et al., 2003). To …

IGC Proceedings (1977-2023)
Inoculants are the most common additives used in making silage. While inoculant effects on fermentation and dry matter (DM) recovery are understood, animal performance effects are often greater than expected. In vitro analyses may help uncover how inoculants affect rumen fermentation and ultimately dairy cattle performance. Our objective was to study how inoculation of lucerne silage affected in vitro gas production.

IGC Proceedings (1977-2023)
Silage quality is determined by factors including the content of butyric acid and ammonium-N. These parameters have to be restricted especially in lightly wilted silages due to a higher risk of clostridia contamination. In this study a novel silage additive was tested in grass silages of low dry matter content. The objective of this experiment was to explore the effect of the silage additive on quality parameters in comparison to an untreated control.

IGC Proceedings (1977-2023)
Silages inoculated with microbial inoculants frequently have a lower pH than non-inoculated crops. Less often inoculated crops have a positive effect on milk production (Weinberg & Muck, 1996). One hypothesis is that bacterial inoculants produce a probiotic effect that could enhance animal performance (Weinberg & Muck, 1996). Our objective was to use the method of Blümmel et al. (1997) to study differences in in vitro fermentation among lucerne silages inoculated with three microbial inoculants.
