Predicting Voluntary Forage Intake Of Supplemented Beef Cattle, Connor Biehler

Masters Theses

A major priority of beef cattle production is to meet animal nutrient requirements in order to achieve a desired level of productivity. Accurately predicting voluntary forage intake (VFI) is necessary to accurately predict the total nutrient intake of grazing or forage-fed beef cattle that are also supplemented with other sources of nutrients. Therefore, the objectives of this experiment were to utilize data from published literature to 1) identify factors that explain variation in VFI, and 2) develop and validate one or more mathematical models that predict VFI or total nutrient intake of grazing or forage-fed and supplemented beef cattle. A …

Effect Of Including Arachis Pintoi In Tropical Forages Diets Megathyrsus Maximus And Brachiaria Humidicola On In Vitro Methane Production, Diana Marcela Valencia Echavarría, Luis Alfonso Giraldo Valderrama, Alexandra Torres, Alejandra Marín Gomez

IGC Proceedings (1997-2023)

Ruminants have the capability to ferment structural carbohydrates found in forages and obtain from them a usable form of energy to produce high quality food, i.e milk and meat (Kamra et al., 2012). However, as a gaseous by-product from the enteric fermentation of those carbohydrates, methane is produced in a significant proportion, being considered as one of the most important greenhouse gases (GHG). In Colombian tropical livestock, inclusion of legumes in on poor quality grasses diets based have allowed an improvement of their nutritive quality, besides enteric methanogenesis reduction because their content of condensed tannins (CT); however, this is not …

Salinity Tolerance Of Forage Range Legumes During Germination And Early Seedling Growth, D. Sevanayak, A. Edna, R. V. Koti, M. B. Doddamani, D. Deb

IGC Proceedings (1997-2023)

Salinity is one of the rising problems causing tremendous yield losses in many regions of the world especially in arid and semiarid regions. In India, about 5.95M ha areas were affected by salinity. Five states viz. Haryana, Punjab, Rajasthan, Gujarat and Andhra Pradesh accounts for 48% of the total salt affected soils of the country. Establishment of seedlings at early growth stages of crop plants as one of the most important determinants of high yield is severely affected by soil salinity. Increasing salinity levels significantly decreased germination parameters, shoot and root length, shoot and root fresh and dry weights …

Selection Of Suitable Varieties Of Grasses For Myanmar, Nang Khan Hline, Khin San Mu, Moe Thida Htun, Lwin Naing Oo, Soe Min Thien, Dezin Soe Lwin, Jue Jue, Aung Aung, Jenny Hanks, Werner Stür, Ganda Nakamanee

IGC Proceedings (1997-2023)

The basal feed resources for ruminants available in most developing countries in the tropics are crop residues, pasture from infertile land, for example communal land, or agro-industrial by-products. These are low in protein and of low digestibility. A major problem facing livestock producers in tropical areas is proper nutrition for their animals during the dry season when pastures, cereal residues and maize stover are limiting in nutritional quality. The researchers in Myanmar have tried to improve the nutritive value of fibrous agricultural residues. Aung Aung et al. (2006) supplemented the sesame and chickpea husk to bulls fed on urea-treated …

IGC Proceedings (1997-2023)

Rye (Secale cereal L.) is well known for its overwintering ability and has the highest tolerance to cold temperature of the small grain cereals such as wheat, barley, and oat. Rye is used as livestock pasture and as green manure in Korea, and its cultivation area for fodder is about 50,000 ha in 2014. Most rye is grown as a fall-sown annual crop, generally called “winter rye”. In Korea, rye cultivation for whole crop silage (WCS) in the winter-season rice field can be considered as a promising way to enhance feed supply. The WCS production can be an efficient …

IGC Proceedings (1997-2023)

Cowpea (Vigna unguiculata (L.) Walp) is a leguminous crop grown throughout West Africa, often in association with pearl millet and sorghum. Cowpea is well adapted to the harsh growing conditions, including low soil fertility, high temperatures, and drought. Cowpea can fix atmospheric nitrogen to improve soil fertility and cropping system productivity. Additionally, farmers feed cowpea fodder to livestock to increase income, and collect the manure produced for use in their fields thereby reduces farmers’ reliance on commercial fertilizers and sustains soil fertility. Previous studies with cowpea indicated that this legume improves soil fertility and enhances the intake and utilization …

The Australian Pastures Genebank, Steve Hughes

IGC Proceedings (1997-2023)

Australian grazing enterprises, including all food and fibre productions, as well as crop rotation, are worth $42 billion per annum to the Australian economy, employing around 693,000 Australian workers. Australia has been a major beneficiary from the introduction and utilization of genetic resources in pasture and forages. Assured access to plant genetic diversity underpins Australia’s ability to maintain agricultural productivity in the face of environmental and economic challenges.

Australia is custodian of potentially the world’s largest and globally significant collection of pasture and forage genetic resources. Much of this is unique and held in state-based collections and represents an invaluable …

Pasture Management To Improve Dry Matter Intake, Marcus F. Rose, Earl Creech, Blair L. Waldron, S. Clay Isom, Michael Peel, Kara Thornton-Kurth, Jacob Hadfield, Kerry A. Rood

All Current Publications

Agricultural producers are constantly looking for ways to maximize returns while reducing input costs. On dairy operations, a move from confinement feeding to pasture grazing offers the potential to reduce costs associated with harvest and storage of feed. In such a transition, producers sometimes report a decline in milk production and growth of livestock—both of which can strongly correlate to dry matter intake. Fortunately, dry matter intake is something that can be influenced by management practices. In this publication, we discuss the pasture management practices to improve dry matter intake.

Does Producing Forages Improve Livelihoods In Dry Areas? The Case Of Afghanistan (On-Going Research), Roberto Tellaria, Serkan Ates, Srinivas Tavva, Hyatullah Esmati

IGC Proceedings (1997-2023)

Agriculture is the main livelihood and a major contributor to the Afghan economy. Livestock production contributes with almost 50% of agricultural GDP in Afghanistan where out of 75% Afghans who live in rural areas, 85% keep some livestock (AusAID and ACIAR, 2011). In particular, small ruminants (sheep and goats) provide small holder rural Afghan families with livelihoods, food and capital. However, insufficient feed is a key constraint that limits productivity, income growth and sustainability in the crop-livestock farming (GIRoA, 2009). The purpose of this research was to assess and identify which forage production technologies offers high productivity and resilience to …

IGC Proceedings (1997-2023)

India is maintaining a livestock population of over 500 million and has a grim situation of forage and feed deficit to the tune of 35.6% green fodder, 10.95% crop residues and 44% concentrate. In term of nutrients, the deficit is expected to the tune of 24.6 and 19.9% respectively by the year 2020. The gap is to be bridged up through development as well as extension of appropriate fodder production technologies suitable for different farming situation strategies. Fifty-eight % of the available fodder comes from grazing land and 42% from stall feeding with crop residues (30%) and leaf fodder (12%). …

The Effect Of Slow-Feeding Hay Nets On Post-Prandial Equine Salivary Cortisol Levels, Grace Simpson

Undergraduate Honors Thesis Projects

Throughout its evolution, the Equus caballus, or horse, developed a physiological response to environmental alterations involving the synthesis and release of cortisol from the hypothalamic-pituitary-adrenal axis, to regulate blood glucose levels, vascular tone and hormone release throughout the body (Ambrojo et al., 2018). With a hypothesis that changing a horse’s feeding method can alter salivary cortisol levels, the aim of this research project was to determine if feeding forage to horses in slow-feeding haynets would significantly reduce acute cortisol salivary level fluctuations, which would be valuable to minimize horses’ stress and increase overall welfare. Two feeding methods …

Influence Of Foliar Nutrition Of Selenium On Phytochelatines Content In The Forage Of Red Clover (Trifolium Pratense L.), Iva Klusoňová, Pavel Horký, Jiří Skládanka, Markéta Komínková, Vojtěch Adam, René Kizek, Petr Škarpa, Lucia Hodulíková

IGC Proceedings (1997-2023)

Selenium (Se) is an essential element significantly influencing health status of animals and humans. The insufficient supply of organism with this element leads to many disorders. Conversely, higher intake can be toxic. As a part of selenoproteins, it regulates the antioxidant system and thus prevents the oxidative destruction of biological membranes and prevents the damage of the body by heavy metals. Consequently, its deficiency disrupts the overall health of animals and humans because of involvement of selenium compounds in many biological functions. Selenium concentration of plant biomass is derived from its content in the soil and may considerably vary depending …
