Cow Preference And Usage Of Free Stalls Compared With An Open Pack Area, J. A. Fregonesi, M. A. G. Von Keyserlingk, D. M. Weary Nov 2009

Cow Preference And Usage Of Free Stalls Compared With An Open Pack Area, J. A. Fregonesi, M. A. G. Von Keyserlingk, D. M. Weary

Housing and Confinement of Farm Animals Collection

Free-stall housing systems are designed to provide a comfortable and hygienic lying area, but some aspects of stall design may restrict usage by cows. The aim of this study was to compare free-stall housing with a comparable lying area (open pack) without stall partitions. We predicted that cows would spend more time lying down and standing in the bedded area when provided access to an open pack than when in free stalls. We also predicted that cows would spend less time standing outside of the lying area and less time perching with the front 2 hooves in the lying area …

Prevalence And Risk Factors For Skin Lesions On Legs Of Dairy Cattle Housed In Freestalls In Norway, C. Kielland, L. E. Ruud, A. J. Zanella, O. Østerås

Housing and Confinement of Farm Animals Collection

Appropriate indoor housing facilities for dairy cattle promote improved animal welfare. Skin alterations are an indicator of dysfunctional housing. The purpose was to determine the relationship between different housing design and skin lesions, hence providing farmers more insight into how to reduce the occurrence of lesions. A cross-sectional study was conducted on 2,335 animals in 232 Norwegian freestall-housed dairy cattle from September 2006 to June 2007. A model was established to investigate risk factors related to the presence of lesions including hair loss, swelling, and wounds on the legs of dairy cattle. Separate models were developed to investigate risk factors …


Obesity Economics For The Western United States, Mariah D. Ehmke, Tina Willson, Christiane Schroeter, Ann Marie Hart, Roger Coupal Oct 2009

Obesity Economics For The Western United States, Mariah D. Ehmke, Tina Willson, Christiane Schroeter, Ann Marie Hart, Roger Coupal

Agribusiness

The estimated obesity-related health care costs across the Western region in 2008 were $16.2 billion (this is an inflation-adjusted estimate based on the work of Finkelstein, Fiebelkorn, and Wang (2004)). 25 The Western populations, the percentage of obese adults in each state, and the estimated annual obesity-related expenditures by state are summarized in Table 1. The cost estimates include only direct health care expenditures related to obesity. The actual cost of obesity is much higher and includes not only obesity-related illness and disease, but also indirect costs resulting from missed work days and lower worker productivity as well as valued …


Managing Maize Production In Shifting Cultivation Milpa Systems In Yucatan, Through Weed Control And Manure Application, David Parsons, Luis Ramirez-Aviles, Jerome H. Cherney, Quirine M. Ketterings, Robert W. Blake, Charles F. Nicholson Sep 2009

Managing Maize Production In Shifting Cultivation Milpa Systems In Yucatan, Through Weed Control And Manure Application, David Parsons, Luis Ramirez-Aviles, Jerome H. Cherney, Quirine M. Ketterings, Robert W. Blake, Charles F. Nicholson

Agribusiness

Milpa cultivation involving cutting an area of forest, burning, and planting crops has existed in the Yucatán Peninsula for more than three millennia. Fallow periods are short and decreasing, leading to a productivity collapse of the system. Technologies that increase yield and maintain plots under cultivation have the potential to decrease the land area needed for family food production, resulting in more mature forests. This study was undertaken to examine the relative importance and potential interactions of declining fertility and increasing weed pressure in reducing maize (Zea mays L.) yields, and to examine the effectiveness of combinations of weed …


Lying Behavior: Assessing Within- And Betweenherd Variation In Free-Stall-Housed Dairy Cows, K. Ito, D. M. Weary, M. A. G. Von Keyserlingk Sep 2009

Lying Behavior: Assessing Within- And Betweenherd Variation In Free-Stall-Housed Dairy Cows, K. Ito, D. M. Weary, M. A. G. Von Keyserlingk

Housing and Confinement of Farm Animals Collection

One of the most important design criteria for dairy cow housing is access to a comfortable lying area. Behaviors such as the time cows spend lying down and how often they lie down can be used to evaluate the quality of stalls; however, assessing lying behavior on farms can be challenging. Indices such as the cow comfort index (CCI) and stall use index (SUI) have been widely used in on-farm assessments. The aims were to establish reliable sampling and recording methods for measuring lying behavior, to evaluate the adequacy of the CCI and SUI as estimates of lying behavior, and …


Preference And Usage Of Pasture Versus Free-Stall Housing By Lactating Dairy Cattle, A. L. Legrand, M. A. G. Von Keyserlingk, D. M. Weary Aug 2009

Preference And Usage Of Pasture Versus Free-Stall Housing By Lactating Dairy Cattle, A. L. Legrand, M. A. G. Von Keyserlingk, D. M. Weary

Housing and Confinement of Farm Animals Collection

The aim of the current study was to assess if cows preferred pasture or indoor housing, and how diurnal and environmental factors affected this preference. Lactating dairy cows (n = 5 groups, each containing 5 cows) were sequentially housed either in a free-stall barn on pasture, or given the choice between the 2 environments. Each group was tested 3 times under each condition, for a total of 21 d, to assess the effects of varying climatic conditions (outdoor temperature ranged from 9.9 to 28.2°C and daily rainfall from 0 to 65 mm/d over the course of the experiment). When provided …


Preference For Pasture Versus Freestall Housing By Dairy Cattle When Stall Availability Indoors Is Reduced, A. C. Falk, D. M. Weary, C. Winckler, M. A. G. Von Keyserlingk Aug 2009

Preference For Pasture Versus Freestall Housing By Dairy Cattle When Stall Availability Indoors Is Reduced, A. C. Falk, D. M. Weary, C. Winckler, M. A. G. Von Keyserlingk

Housing and Confinement of Farm Animals Collection

Providing cattle with access to pasture has been shown to yield benefits, including access to more space, fewer agonistic interactions, better air quality, and the ability to perform a greater range of normal behaviors. Preference for pasture appears to depend on several parameters, including weather conditions and availability of shade. The primary aim of this study was to evaluate the preference for pasture versus inside a freestall barn with variable stocking densities at the stalls. We also investigated the effect of temperature-humidity index (THI) and precipitation on this preference. Overall, cows spent on average 13.7 ± 2.6 h/d (mean ± …

The Stall-Design Paradox: Neck Rails Increase Lameness But Improve Udder And Stall Hygiene, F. Bernardi, J. A. Fregonesi, C. Winckler, D. M. Veira, M. A. G. Von Keyserlingk, D. M. Weary Jul 2009

The Stall-Design Paradox: Neck Rails Increase Lameness But Improve Udder And Stall Hygiene, F. Bernardi, J. A. Fregonesi, C. Winckler, D. M. Veira, M. A. G. Von Keyserlingk, D. M. Weary

Housing and Confinement of Farm Animals Collection

Housing conditions for dairy cows are thought to af-fect lameness, but almost no experimental work has addressed this link. The aim was to assess the effect of one feature of free-stall design, the position of the neck rail, testing the prediction that cows will be more likely to become lame if using pens with the neck rail positioned such that it prevents standing fully inside the stall. Cows (n = 32) were housed in 8 pens. Treat-ments were tested using a crossover design; treatments were allocated alternately to pens at the beginning of the experiment and switched halfway through the …


Exponential Growth, Animal Welfare, Environmental And Food Safety Impact: The Case Of China’S Livestock Production, Peter J. Li Jun 2009

Exponential Growth, Animal Welfare, Environmental And Food Safety Impact: The Case Of China’S Livestock Production, Peter J. Li

Agribusiness Collection

Developmental states are criticized for rapid “industrialization without enlightenment.” In the last 30 years, China’s breathtaking growth has been achieved at a high environmental and food safety cost. This article, utilizing a recent survey of China’s livestock industry, illustrates the initiating role of China’s developmental state in the exponential expansion of the country’s livestock production. The enthusiastic response of the livestock industry to the many state policy incentives has made China the world’s biggest animal farming nation. Shortage of meat and dairy supply is history. Yet, the Chinese government is facing new challenges of no less a threat to political …

Cow Comfort In Tie-Stalls: Increased Depth Of Shavings Or Straw Bedding Increases Lying Time, C. B. Tucker, D. M. Weary, M. A. G. Von Keyserlingk, K. A. Beauchemin

Housing and Confinement of Farm Animals Collection

Over half of US dairy operations use tie-stalls, but these farming systems have received relatively little research attention in terms of stall design and management. The current study tested the effects of the amount of 2 bedding materials, straw and shavings, on dairy cattle lying behavior. The effects of 4 levels of shavings, 3, 9, 15, and 24 kg/stall (experiment 1, n = 12), and high and low levels of straw in 2 separate experiments: 1, 3, 5, and 7 kg/stall (experiment 2, n = 12) and 0.5, 1, 2, and 3 kg/stall (experiment 3, n = 12) were …

Assessing Lameness In Cows Kept In Tie-Stalls, K. A. Leach, S. Dippel, J. Huber, S. March, C. Winckler, H. R. Whay

Housing and Confinement of Farm Animals Collection

Identifying lame cows and quantifying the prevalence of lameness are important elements of cattle welfare assessment that are generally achieved by methods involving observations of each animal walking. There is no published method for assessing lameness in cows confined in tie-stalls. The objective of this study (carried out within the European Commission’s Welfare Quality® project) was to develop a suitable method and validate it for lameness detection against a published locomotion score. A series of indicators of lameness visible in tied cows was formalized into a stall assessment protocol. This was validated against a traditional locomotion score and tested for …

Stephens, Christopher B. Barrett, Douglas R. Brown, Johannes Lehmann, David Mbugua, Solomon Ngoze, Charles F. Nicholson, David Parsons, Alice N. Pell, Susan J. Riha

Agribusiness

We investigate natural resource-based poverty traps using a simulation model of smallholder farms in highland Kenya. Simulation modeling allows for detailed examination of the complex interactions and feedback between farm-household economic decision-making and long-term soil dynamics, which may contribute to persistent poverty among smallholders in this region. We examine the effects of changing initial endowments of land, labour and stocks of on-farm soil organic matter on the long-term welfare of these households. We find that larger farms are better able to cope with both labour shocks and deteriorating natural capital than smaller farms, with smaller farms remaining poor and unable …

Assam is endowed with copious aquatic wealth in the form of beels, swamps, ponds and rivers. The floodplain wetlands (beels) extending over one lakh hectare, constitute the most important fishery resource of the state. The beels are considered as one of the most productive ecosystems owing to their characteristic interactions between land and water system. These wetlands are the common property resource and under different management regimes. Livelihood of fishers’ family from time immemorial is dependent upon fishing in floodplain wetlands. Fishers include the actual fishermen belonging to the Schedule castes and the Maimal community of the district of Cachar. …

Human Health Collection

What we eat is rapidly becoming an issue of global concern. With food shortages, the rise in chronic disease, and global warming, the impact of our dietary choices seems more relevant today than ever. Globally, a transition is taking place toward greater consumption of foods of animal origin, in lieu of plantbased diets. With this transition comes intensification of animal agriculture that in turn is associated with the emergence of zoonotic infectious diseases, environmental degradation, and the epidemics of chronic disease and obesity. Health professionals should be aware of these trends and consider them as they promote healthier and more …

Setting Agricultural Science Strategy In Tumultuous Economic Times, Jennifer S. James, Julian M. Alston, Philip G. Pardey

Agribusiness

The international competitiveness and prosperity of U.S. agriculture depends on steady and rapid productivity growth fueled by public agricultural research and development (R&D). Agricultural science benefits consumers and the environment, not just farmers. Enhanced productivity as a result of agricultural R&D means that consumers have access to a more abundant, cheaper, safer, higher quality, and more diverse and convenient food supply, produced with less stress on natural resources and the environment. From a global perspective, productivity growth allows agricultural production to increase faster than demand; food has become much cheaper over time in spite of a rapidly growing world population …

The Economics Of Agricultural R&D, Julian M. Alston, Philip G. Pardey, Jennifer S. James, Matthew A. Andersen

Agribusiness

Agricultural research has transformed agriculture and in doing so contributed to the transformation of economies. Economic issues arise because agricultural research is subject to various market failures, because the resulting innovations and technological changes have important economic consequences for net income and its distribution, and because the consequences are difficult to discern and attribute. Economists have developed models and measures of the economic consequences of agricultural R&D and related policies in contributions that relate to a very broad literature ranging across production economics, development economics, industrial organization, economic history, welfare economics, political economy, econometrics, and so on. A key general …


Structural Changes In U.S. Agricultural Production And Productivity, Jennifer S. James, Julian M. Alston, Philip G. Pardey, Matthew A. Andersen Jan 2009

Structural Changes In U.S. Agricultural Production And Productivity, Jennifer S. James, Julian M. Alston, Philip G. Pardey, Matthew A. Andersen

Agribusiness

The structure of U.S. agricultural production changed dramatically during the 20th Century. Major technological innovations transformed the relationship between agricultural inputs and outputs, and contributed to rapid increases in agricultural productivity. However, evidence is mounting that suggests we have entered a new era, with substantially lower rates of productivity growth. In this article, we examine trends and spatial patterns in agricultural input use, production of outputs, and productivity. We focus on productivity growth over the period 1949–2002, and find a statistically significant slowdown in productivity growth after 1990.


Economics And Policy Context For The Biological Management Of Soil Fertility (Bmsf) In Ethiopia, Habtamu T. Kassahun, Charles F. Nicholson, Dawit Solomon, Amy S. Collick, Tammo S. Steenhuis Jan 2009

Economics And Policy Context For The Biological Management Of Soil Fertility (Bmsf) In Ethiopia, Habtamu T. Kassahun, Charles F. Nicholson, Dawit Solomon, Amy S. Collick, Tammo S. Steenhuis

Agribusiness

Many developing countries implement programs and policies to increase or maintain soil fertility, with the objectives of increased crop yields and decreased poverty. However, few countries give emphasis to the biological management of soil fertility (BMSF) compared to more traditional approaches. Ethiopia emphasizes the use synthetic fertilizers to increase food security and reduce poverty, with little attention to BMSF. This paper examines the long term fertilizer consumption and agricultural productivity response trend and discusses the potential for BMSF to promote agricultural productivity and reduce poverty in Ethiopia. The paper also discusses the Economics and Policy Context for BMSF for the …

Relationship Between Pre-Slaughter Stress Responsiveness And Beef Quality In Three Cattle Breeds, V. Muchenje, K. Dzama, M. Chimonyo, P. E. Strydom, J. G. Raats Jan 2009

Relationship Between Pre-Slaughter Stress Responsiveness And Beef Quality In Three Cattle Breeds, V. Muchenje, K. Dzama, M. Chimonyo, P. E. Strydom, J. G. Raats

Slaughter and Slaughtering Practices Collection

The relationship between stress responsiveness and beef quality of 40 Nguni, 30 Bonsmara and 30 Angus steers was determined. The L* values, pHu, cooking loss (CL) and Warner-Bratzler shear force (WBSF) were determined. Catecholamine levels were determined from urine samples collected at slaughter. Bonsmara steers had the highest (P < 0.05) levels of catecholamines with respective epinephrine, norepinephrine and dopamine concentrations of 10.8, 9.7 and 14.8 nmol/mmol. Nguni steers had the lowest (P < 0.05) levels of catecholamines, with respective catecholamine concentrations of 5.1, 4.3 and 4.0 nmol/mmol. In the Nguni steers, there were significant (P < 0.05) correlations between catecholamines and L* and between dopamine and tenderness in meat aged for two days (WBSF2). In the Bonsmara, dopamine was correlated (P < 0.05) pHu, WBSF2 and CL. No significant correlations were found in the Angus. Therefore the relationship between stress responsiveness and certain beef quality traits may not be similar in different breeds.

Welfare Issues With Conventional Manual Catching Of Broiler Chickens And Turkeys

Agribusiness Reports

Approximately 9 billion chickens and 270 million turkeys are raised for meat annually in the United States. When these farmed birds reach market weight, they must be caught and crated for transport from production facilities to slaughter plants. Conventional manual catching results in severely compromised welfare. Birds experience stress and fear, and can be physically harmed, suffering bruises, broken bones, dislocated joints, and other injuries. Alternatives to conventional manual catching practices that improve bird welfare exist, including mechanical harvesters, gentle manual catching, and, for turkeys, herding into specially designed transport crates.
