Predicting Nutritional Requirements And Lactation Performance Of Dual-Purpose Cows Using A Dynamic Model, O. Reynoso-Campos, D. G. Fox, R. W. Blake, M. C. Barry, L. O. Tedeschi, C. F. Nicholson, H. M. Kaiser, P. A. Oltenacu

Agribusiness

A dynamic application of the Cornell Net Carbohydrate and Protein System (CNCPS) model was developed to predict annual cycles in animal nutrient requirements and performance of dual-purpose (milk and beef) cows. Interactions from mobilisation and repletion of body tissue reserves and feed biological values are accounted with a time step of one day, which considers physiological status of the animal, variation in dietary composition, and other environmental factors. This outcome was achieved by modifying the input and output structure of the CNCPS version 4.0 to compute body weight and changes in body reserves based on predicted milk production, intake of …

Agroecosystems Analysis From The Grass Roots: A Multidimensional Experiential Learning Course, Mary Wiedenhoeft, Steve Simmons, Ricardo Salvador, Gina Mcandrews, Charles A. Francis, James W. King, David Hole

Department of Agricultural Leadership, Education, and Communication: Faculty Publications

An intensive, experiential travel course in Agroecosystems Analysis was conducted in Iowa, Minnesota, and Nebraska (United States) during summers of 1998 and 1999. The intended student audience was advanced undergraduate and beginning graduate students. Pretravel readings and a week-long series of farm visits, which consisted of in-depth interviews with the farmers and their families, prepared student teams to analyze and evaluate the production, economic, environmental, and social sustainability of 10 farms. Students shared their analyses both orally and in written reports. Based on a multifaceted student evaluation process, we found that participants were highly motivated, strongly engaged with the course …

Effects Of Three Types Of Free-Stall Surfaces On Preferences And Stall Usage By Dairy Cows, Cassandra B. Tucker, Daniel M. Weary, David Fraser

Housing and Confinement of Farm Animals Collection

One important criterion in choosing appropriate housing systems for dairy cattle is that the freestall provides a comfortable surface for the cow. This paper describes two experiments testing the effects of commonly used lying surfaces on stall preference and stall usage by Holstein cows. In both experiments, 12 cows were housed individually in separate pens. Each pen contained three free stalls with a different surface: deep-bedded sawdust, deep-bedded sand, and a geotextile mattress covered with 2 to 3 cm of sawdust. The animals were restricted to each surface in turn, in a random order for either 2 (Experiment 1) or …

The Eu Ban On Battery Cages: History And Prospects, Michael C. Appleby

State of the Animals 2003

On June 15, 1999, the European Union (EU) passed a directive on the welfare of laying hens, requiring that battery cages (so called because they are arranged in batteries of rows and tiers) be phased out by 2012. Enriched laying cages (which may also be arranged in batteries but which provide increased area and height, when compared with conventional cages, and a perch, nest box, and litter area) will still be allowed. This chapter outlines how this directive came about, and the social, economic, and political issues involved. It considers prospects for the future, both within and outside the EU, …

The State Of Meat Production In Developing Countries: 2002, Neil Trent, Peter Ormel, Jose Luis Garcia De Siles, Gunter Heinz, Morgane James

Two organizations—one dedicated to the elimination of animal suffering and the other to encouraging sustainable agriculture and rural development— have joined forces to address animal welfare issues in the global livestock industry. The mission of The Humane Society of the United States (HSUS) and its international arm, Humane Society International (HSI), is to create a humane and sustainable world for all animals, including people, through education, advocacy, and the promotion of respect and compassion. The Food and Agriculture Organization (FAO) of the United Nations has as a specific priority to increase food production and food security while conserving and managing …

Horse Welfare Since 1950, Katherine A. Houpt, Natalie Waran

State of the Animals 2003

There are approximately 6.9 million horses in the United States, more than in any other country in the world (American Horse Council 2000) (Table 1). That fact alone should inspire Americans to improve equine welfare, although it must be said that the state of domesticated horses is better now than it was fifty years ago.

At the turn of the millennium, the most pressing welfare issues of the domestic horse surround conditions found in slaughter and transport to slaughter; pari-mutuel racing; the pregnant mare urine (PMU) industry; the competitive and show industry; and in the development of husbandry-related stereotypes. (Urban …

The Tenderisation Of Shin Beef Using A Citrus Juice Marinade, Roisin Burke, Frank Monahan

Articles

The effectiveness of organic acids (acetic, citric, lactic) and a citrus juice marinade as tenderising agents in shin beef muscle was investigated. At 0.2 M, citric acid was more effective as a tenderising agent than acetic or lactic acid. Immersion of shin beef strips in citric acid (0–0.05 M) showed that a significant tenderising effect was obtained above a concentration of 0.013 M. When shin beef strips were immersed in the citrus juice marinade (31% orange juice, 31% lemon juice, 38% distilled water) mean pH decreased from 5.7 to 3.1 and mean sample weight increased by ∼65%. The mean Warner–Bratzler …

Reconstruction Services For Iraq, Department Of Agriculture And Food, Western Australia

As Iraq enters a new phase in its history, Australia is poised to play a leading role in the reconstruction of Iraq's agricultural sector. Initially, food security will be the main priority with later phases of the development process concentrating on harnessing agriculture as an engine for economic growth and poverty alleviation.

Western Australia has a long tradition of supplying countries of the Middle East with high quality foodstuffs and in implementing agricultural development projects. The Middle East is one of Western Australia's key trading partners, consuming an annual food production valued in excess of $1 billion. In recent times, …

The Crop-Livestock Subsystem And Livelihood Dynamics In The Harar Highlands Of Ethiopia, Habtemariam Kassa, Robert W. Blake, Charles F. Nicholson

Agribusiness

Policy makers and extension planners often assume smallholder mixed farming systems are incapable of evolving fast enough to meet growing food demands and that livestock are relatively unimportant to household food production or welfare (FDRE, 1994), except for intensive units. The resulting policy promotes substitution of either intensive cropping or livestock production in place of the traditional mixed portfolio. Although widely promoted in the Harar Highlands, farmers resist these recommendations in favour of more diverse and integrated systems with crops, livestock, and non-agricultural activities. The contrast between what policy makers and development practitioners think and what farmers do signifies misunderstanding …

Soil, Plant And Cattle Nutrient Dynamics On Pastures Of The Western Amazon Of Brazil, B. Rueda, R. W. Blake, E. Fernandes, Charles F. Nicholson, J. F. Valentim

Agribusiness

Cattle production on Brachiaria pastures is a primary use of cleared forestland in the western Brazilian Amazon. About 6.8 million hectares in the States of Acre and Rondônia have been deforested, where 75% of land is now grazed (IBGE, 1998). The principal pasture species are B. brizantha and B. decumbens with the latter in decline from spittlebug susceptibility (Deois incompleta; Gonçalves et al., 1996). The general pattern of pasture establishment in the Amazon basin includes felling and burning forest biomass, planting annual crops for one to three years (especially on small farms), and then seeding to grasses. The …

Livestock Land Use Change, And Environmental Outcomes, Robert W. Blake, Charles F. Nicholson

Agribusiness

Rapid predicted worldwide growth in demand for animal products to 2020—the so-called “next food revolution” in animal agriculture—portends complex interactions among people, biological and geophysical resources, and economic objectives. A restructuring of global food demands is expected: in contrast to current patterns, most (>60%) global production of meat and milk will be consumed by households in the developing countries (Delgado et al., 1999). The key drivers of this change are income growth, population growth, urbanization, and increased opportunities for trade. We identified some of the environmental risks, and recuperative effects, of animal agriculture in a recent article (Nicholson et …

The Economic Feasibility Of Forming A California Wheat Cooperative, Jay E. Noel, James J. Ahern, David J. Schaffner, Jill Johnson, Kristina Muelrath, Kyle Schroeder

Agribusiness

Recent concerns relative to California farm gate prices for wheat and a lack of profitability in wheat production has been expressed by a group of California wheat growers. Their dissatisfaction has resulted in their consideration to form a California wheat grower cooperative. The cooperative would become the marketing agent for the growers and potentially allow growers to pool their production for greater market power as well as capture profits beyond the farm gate. Two feasibility issues are addressed by the study: 1) The organizational feasibility of forming the cooperative, and 2) The economic feasibility of a California wheat growers cooperative …

Taxes And Quality: A Market-Level Analysis, Jennifer S. James, Julian M. Alston

Agribusiness

A conventional assumption of product homogeneity when the commodity of interest is actually heterogeneous will lead to errors in an analysis of the incidence of policies, such as taxes. In this article, an equilibrium displacement model is used to derive analytical solutions for price, quantity, and quality effects of ad valorem and per unit taxes. The results show how parameters determine the effects of tax policies on quality. The potential for tax-induced distortions in quality, and the distributive consequences of those distortions, are illustrated in a case study of the market for Australian wine.

A Multiattribute Utility Analysis Of Technological Choice In The California Wild Rice Industry, Jay E. Noel, James J. Ahern, Jess Errecarte, Kyle Schroeder

Agribusiness

The California wild rice industry in 2001 is undergoing change. This change is being driven by increased wild rice production, changes in wild rice demand, and buyer concerns relative to product quality and food safety. These changes necessitate the need for the industry to evaluate its operational and marketing strategies. A major concern of the industry is how to meet the on-going changes while remaining profitable. The major emphasis of this study to evaluate two of the technological choices that are available to meet those changes. The technologies are a traditional technology and newer experimental technology that has been conceptualized, …
