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 Feb 2023

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 (1993-2023)

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 Feb 2023

Sustained Aerobic Stability Of By-Products Silage Stored As A Total Mixed Ration, N. Nishino, H. Hattori, H. Wada

IGC Proceedings (1993-2023)

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 …

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 Feb 2023

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 (1993-2023)

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 Feb 2023

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 (1993-2023)

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 Feb 2023

Effect Of Stage Of Maturity On The Nutrient Content Of Alfalfa, Y. Tyrolova, A. Vyborna

IGC Proceedings (1993-2023)

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.

How Noise Thresholds Affect The Information Content Of Stellar Flare Sequences, Elmer C. Rivera, Jay R. Johnson, Jonathan Homan, Simon Wing

Faculty Publications

Systems that exhibit discrete dynamics can be well described and reconstructed by considering the set of time intervals between the discrete events of the system. The Kepler satellite has cataloged light curves for many Sun-like stars, and these light curves show strong bursts in intensity that are associated with stellar flares. The waiting time between these flares describes the fundamental dynamics of the stars and is driven by physical processes, such as flux emergence. While it is rather straightforward to identify large flares, the identification of weaker flares can be challenging because of the presence of noise. A common practice …
