Yield And Composition Of Forage Maize: Interaction Of Harvest Date, Cultivar And Plastic Mulch, E. M. Little, P. O'Kiely, J. C. Crowley, G. P. Keane
IGC Proceedings (1977-2023)
Forage maize is established as a crop with the potential to consistently supply high yields of quality forage on some Irish farms. Despite its success, considerable variability in crop yield, quality and maturity at harvest can exist from year to year. These reflect differing prevailing weather conditions, particularly temperature during May to September. The use of plastic mulch has increased the likelihood of achieving higher yields of high quality crops and has permitted maize production to extend into areas once considered unsuitable for the crop. In this experiment two cultivars of differing maturity were grown with or without plastic mulch …

Fermentation Characteristics Of Maize/Sesbania Bi-Crop Silage, M. Kondo, J. Yanagisawa, K. Kita, H. Yokota
IGC Proceedings (1977-2023)
Maize is one of the main forages for dairy production and is a suitable material for silage making because of high fermentable carbohydrates, high counts of lactic acid bacteria (LAB) and low buffering capacity (BC) (Nishino et al. 2003; McDonald et al. 1991). Whole crop maize silage is high in energy but low in crude protein (CP). On the other hand, legumes are high in CP but difficult to conserve because of their low water soluble carbohydrates (WSC) and high BC. It might be possible that maize/legume bi-crop silage compensate for their negative points. Sesbania is a legume originated …
Ensiling Of Tannin-Containing Sorghum Grain,

University of Rostock, Germany
Ensiling Of Tannin-Containing Sorghum Grain, E. M. Ott, Y. Acosta Aragón, M. Gabel
IGC Proceedings (1977-2023)
Sorghum is known as important feed-stuff in tropical regions where rainfall is insufficient for the cultivation of maize. Furthermore, those sorghum cultivars rich in tannins are naturally protected to a certain extent against bird damage, insect pests and moulds. Nevertheless, tannins impair the feed quality. Thus, the objectives of this study were to investigate whether ensiling could be a suitable preservation method for sorghum grain originally rich in tannins and if it is possible to reduce tannin content during fermentation.

Effects Of Varying Dietary Ratios Of Lucerne To Maize Silage On Production And Microbial Protein Synthesis In Lactating Dairy Cows, G. A. Broderick, A. F. Brito
IGC Proceedings (1977-2023)
Lucerne silage (LS) is high in total CP and rumen degraded protein (RDP) but low in fermentable energy, while maize silage (MS) is a good source of fermentable energy but low in RDP. Thus, these silages are complementary and feeding them at optimum ratio should increase nutrient efficiency in lactating cows. Dhiman & Satter (1997) observed greater milk yield when the dietary forage was 2/3 LS and 1/3 MS. The objective of this experiment was to optimise the dietary LS:MS ratio for production, microbial protein and N utilisation.

Sustained Aerobic Stability Of By-Products Silage Stored As A Total Mixed Ration, N. Nishino, H. Hattori, H. Wada
IGC Proceedings (1977-2023)
Ensiling a total mixed ration (TMR) has been practiced in Japan when high-moisture by-products are used as ruminant feed. Wet brewers grains (BG) are a common feed resource and approximately one million t are produced annually. Nishino et al. (2003; 2004) reported that, although silage would easily deteriorate in the presence of air when wet BG were ensiled alone, the spoilage could be avoided when stored as a TMR. Interestingly, the resistance to deterioration was consistently found whether high (> 106 cfu/g) or no (/g) yeasts were detected at unloading. In this study, changes during ensilage and after exposure …

Effect Of Variety And Species On The Chemical Composition Of Lotus When Ensiled, C. L. Marley, R. Fychan, R. Jones
IGC Proceedings (1977-2023)
Research has shown that there are positive benefits from using Lotus as a grazing forage for ruminants. These findings warrant studies into the suitability of different varieties for silage production. In this experiment, we investigated the chemical composition of 13 birdsfoot trefoil varieties and 1 greater birdsfoot trefoil when ensiled.

Cob Development In Forage Maize: Influence Of Harvest Date, Cultivar And Plastic Mulch, E. M. Little, P. O'Kiely, J. C. Crowley, G. P. Keane
IGC Proceedings (1977-2023)
Forage maize grown for silage tends to be a compromise between reproductive and vegetative yield, and the cob component is the main driver of feeding value (Keane et al., 2003). Thus the aim is to produce a well-developed crop of high dry matter (DM) and starch content reflecting large cobs of well-filled grains rather than crops with low DM and starch contents reflecting poorly developed (immature) cob components at harvest. The use of plastic mulch can increase total DM yields with the increase in cob yield accounting for 75% of the total yield increase (Easson & Fearnehough, 1997). In …

The Influence Of Crop Maturity And Type Of Baler On Whole Crop Barley Silage Production, P. Lingvall, M. Knicky, B. Frank, B. Rustas, J. Wallsten
IGC Proceedings (1977-2023)
Bale ensiling is based on long cut forages. Earlier studies (Honig, 1984; 1987) have shown the importance of laceration and high density in preventing fungi growth and storage instability. On the other hand use of an efficient baling technology reduces the time between moving and wrapping of bale to less than 10 minutes with a combi-baler compared to two hours with a separate wrapper. Even during feeding late fermentation is restricted as the bale is fed within some hours after opening. Ensiling of whole crop cereals needs the addition of silage additives to avoid clostridial fermentation (Weissbach et al., …

Effect Of Stage Of Maturity On The Nutrient Content Of Alfalfa, Y. Tyrolova, A. Vyborna
IGC Proceedings (1977-2023)
Alfalfa (Medicago sativa), one of the major agricultural crops in the Czech Republic, is grown on 15.8% of the arable land. Alfalfa silage forms a substantial part of diets for farm animals. It is very important to choose a suitable term of harvesting for ensilage from the view of optimal nutrient content. The stage of maturity at cutting has large effects on each component, except crude protein (Yu et al., 2004). Alfalfa can be difficult to ensile due to a high buffering capacity and a low WSC content.

IGC Proceedings (1977-2023)
The amount of maize grown in Poland has increased rapidly. Nowadays it takes about 600,000 ha, 40% of which is used as silage. Changing climate in Poland, with dry summer followed by wet autumn with ground frost causes extensive moulds contamination and high presence of the fusarium toxins in the maize during the harvest. The norms accepted in the EU concerning the acceptable level of deoxynivalenol (DON) and zearalenol (ZON) in feedstuffs for cattle require detailed examination of this problem as it decides on the health quality and production results. The aim of the study was to evaluate the effects …

Effects Of Feeding Legume Silage With Differing Tannin Levels On Lactating Dairy Cattle, U. C. Hymes Fecht, G. A. Broderick, R. E. Muck
IGC Proceedings (1977-2023)
Condensed tannins (CT) bind to plant proteins in the rumen, reducing protein degradation to ammonia and increasing milk production and milk protein (e.g. Waghorn, 1987). Previous research showed that the reduced soluble non-protein nitrogen (NPN) content of red clover (Trifolium pratense) silage (RCS) was related to its greater N efficiency relative to lucerne (Medicago sativa) silage (LS) (Broderick et al., 2001). Commercial cultivars of birdsfoot trefoil (Lotus corniculatus; BFT) contain modest levels of CT which reduce NPN formation in silage (Albrecht & Muck, 1991). The objective was to compare silages made from BFT …

Blood Meal As A Source Of Histidine For Cattle Fed Grass Silage And Barley, R. Berthiaume, C. Lafrenière
IGC Proceedings (1977-2023)
Previous research has shown that cattle fed grass silage are responsive to protected amino acids (Veira et al., 1991). Methionine and lysine were suggested as the most limiting amino acids for grass silage diets. Recently, Korhonen et al. (2000) have shown that histidine is the first limiting amino acids for dairy cows fed grass silage and barley-based concentrates. However, histidine is not available in a rumen protected form and needs to be provided through dietary ingredients. Blood meal is rich in histidine. This trial was designed to determine the effect of increasing histidine supply through blood meal on …

Nutritive Value For Finishing Beef Steers Of Wheat Grain Conserved By Different Techniques, P. Stacey, P. O'Kiely, A. P. Moloney, F. P. O'Mara
IGC Proceedings (1977-2023)
Wheat grain harvested at dry matter (DM) concentrations above 860 g/kg is slow to deteriorate during long-term storage. However, high moisture grain (HMG) ranging from below 600 to 750 g DM/kg is conserved on some farms in the form of anaerobic storage of acid-treated, rolled wheat (AR) and urea-treated whole-wheat (UN) (Stacey et al., 2003). This experiment quantified the nutritive value for beef cattle of standard wheat grain (propionic acid-treated and rolled:PR) compared to AR and UN at different levels of intake.

Effect Of Additive Treatment On Meat Quality, V. Vrotniakiene, J. Jatkauskas
IGC Proceedings (1977-2023)
Major components of meat quality are physico-chemical properties (including visual appearance and tenderness) and dietetic properties (i.e. fat content and fatty acid composition) (Razminowicz et al., 2004). Physico-chemical and technological properties of meat are influenced by feeding system, feeds quality and various feeds additives (Brzoska et al., 1999). The aim of the present study was compare the influence of untreated, inoculated and chemically-treated legume-grass silage on carcass composition and physico-chemical properties of meat when fed to fattening bulls.

Replacement Of Maize/Soybean Meal Concentrate By High Moisture Maize Grain Plus Wholeseed Soybean Silage For Cattle, C. C. Jobim, A. F. Branco, V. F. Gai, U. Cecato
IGC Proceedings (1977-2023)
Ensiling high moisture maize grain with wholeseed soybean can increase quality of silage, mainly in relation to protein and energy (Jobim et al., 2002) working as concentrate. This fact contributes to reduced use of concentrate and costs for milk and beef production, and costs related to grain storage on the farms. The objective of this study was to evaluate the nutritive value of high moisture maize grain plus wholeseed soybean silage through partial and total digestibility in cattle.

The Effects Of Alfalfa Silage Harvesting Systems On Dry Matter Intake Of Friesland Dairy Ewes In Late Pregnancy, H. F. Elizalde
IGC Proceedings (1977-2023)
With the recent introduction of alfalfa in Chilean Patagonia (Aisén), its utilisation as silage has to be reviewed relative to animal performance. The effect of silage chop length on the voluntary intake has been evaluated in different species, with sheep being more sensitive to chop length than cattle (Dulphy et al., 1984). The objective of this experiment was to evaluate the effects of different alfalfa silage chop lengths on dry matter (DM) intake and eating behaviour of Friesland dairy ewes in late pregnancy.

Effect Of Feeding Red Clover, Lucerne And Kale Silage On The Voluntary Intake And Liveweight Gain Of Growing Lambs, R. Fychan, C. L. Marley, M. D. Fraser, R. Jones
IGC Proceedings (1977-2023)
Despite a need for alternative forages to provide home-grown sources of protein (Wilkins & Jones, 2000), there have been few studies comparing the effects of such forages on lamb production when fed as silage. In this experiment the effects of offering ensiled red clover (Trifolium pratense), lucerne (Medicago sativa) and kale (Brassica oleracea) on voluntary intake and liveweight gain in growing lambs were compared.
