An Hsi Report: Adopting A Cage-Free Production Policy For Animal Products In Brazil, Humane Society International

HSI REPORTS

Farm animal welfare is becoming an important concern for governments, producers, and consumers worldwide. In particular, intensive confinement systems, such as battery cages and gestation crates, have been acknowledged as severely impairing to the physical comfort and expression of natural behaviors of animals. The European Union and select states in the United States have already passed bills eliminating these housing systems over the next several years. Numerous international retail and food production companies, including Burger King (North America), Smithfield Foods, and McDonald’s (Europe) are committed to gradually eliminating the use and sale of eggs and pork produced via intensive confinement …

A Critical Review Of Electrical Water-Bath Stun Systems For Poultry Slaughter And Recent Developments In Alternative Technologies, Sara J. Shields, A. B. M. Raj

Agribusiness Collection

Prior to slaughter, most farmed birds move through a constant-voltage, multiple- bird, electrical water-bath stun system. Using this system subjects live birds to stressful and painful shackling, and the potential exists for them to receive prestun electric shocks and induction of seizures while still conscious. The existing elec- trical water-bath stunner settings, particularly those used in U.S. slaughter plants, are not necessarily based on sound scientific data that they produce a consistent, immediate stun, and research indicates that they are not effective in all birds. Further, in multiple-bird, electrical water-bath systems, birds may miss the stunner completely. Evidence suggests that …

The Welfare Of Animals In The Pig Industry

Agribusiness Reports

The discordance between the behavioral needs of pigs and the life afforded to those raised commercially for the meat industry has created many animal welfare problems. Methods of pig production have changed substantially over the last several decades, and industrialized confinement operations have largely overtaken small, diversified farms. Overcrowded in indoor, barren environments, pigs in commercial production facilities are offered little opportunity to display their full range of complex social, foraging, and exploratory behavior. Behavioral abnormalities, such as tail-biting and aggression, arise due to environmental and social deficiencies. Poor air quality and intensive confinement may lead to health problems, and …

The Welfare Of Piglets In The Pig Industry

Agribusiness Reports

Pig production has changed dramatically over the last several decades, and most piglets are now raised on industrialized commercial operations that confine thousands of animals on one site. In these facilities, piglets are born and reared under conditions that dramatically contrast with the natural environment they are biologically adapted to fit. In nature, a mother sow builds a nest of twigs and leaves for the birth of her litter, and, after several days, the piglets gradually begin to leave the nest, explore their environment by rooting and nibbling, and slowly integrate into a larger family group. Piglets on commercial production …

Welfare Issues With Furnished Cages For Egg-Laying Hens

Agribusiness Reports

Furnished cages were developed in response to criticisms about conventional battery-cage confinement of laying hens in commercial egg production. Battery cages—small, barren, wire enclosures—restrictively confine the birds, depriving them of the opportunity to display many important patterns of behavior. In contrast, furnished cages are typically equipped with a nest box, perch, and dustbathing area, thereby providing more behavioral outlets than conventional cages. However, similar to conventional battery cages, furnished cages provide an unacceptably limited amount of space per bird; prevent many important locomotory activities, including running, jumping, flying, and wing-flapping; and constrain perching, dustbathing, and nesting. The severe locomotory restriction …

The Impact Of Animal Agriculture On The Environment And Climate Change In Brazil

Agribusiness Reports

The intensification of farm animal production in industrialized agricultural systems, or factory farms, compromises animal welfare and degrades the environment. Animal agriculture inefficiently consumes natural resources, contributes to deforestation, and produces immense quantities of animal waste, threatening water and air quality and contributing to climate change. The Food and Agriculture Organization (FAO) of the United Nations estimated in 2006 that animal agriculture was responsible for 18% of global, anthropogenic, or humaninduced, greenhouse gas emissions and was ―by far the single largest anthropogenic user of land."

Understanding Mortality Rates Of Laying Hens In Cage-Free Egg Production Systems

Agribusiness Reports

In cage-free egg production systems, concerns have been raised over hen mortality rates. High mortality is an obvious indicator of poor welfare, and problems should be addressed without delay. It is important to note, however, that mortality can vary substantially between hen flocks, and that some cage-free systems have healthy flocks that do not suffer substantial death losses. These systems can serve as models for the rest of the industry, since mortality is not inherent to any particular system, but a consequence of how well the system is managed.

Aircraft Leasing With Contracts, Qiong Zuo

Dissertations and Theses Collection (Open Access)

We study a problem of rental rate pricing and rental contract designing in aircraft leasing industry. In a framework of Stackelberg game, the system is composed of an airline company (carrier) and an aircraft leasing company (lessor). Acting as the leader, the lessor announces daily rental rates and/or provides long-term contracts on a finite horizon with multiple periods. For each period, the carrier determines the aircraft leasing number to adjust the flight capacity, and applies a dynamic pricing policy for air-tickets based on a seasonally stochastic demand and some economic factor, such as oil price. We find the optimal policies …

Procure Financing For Shipping By Auctions, Kekun Wu

Dissertations and Theses Collection (Open Access)

We study a risk management problem in the scenario of ship procurement. A shipping firm faces a certain financing pressure for the procurement of a new ship. On the other hand, the capacity of the ship excesses the demand requirement of the firm. The firm wants to reduce the payment and control the risk by selling a percentage of capacity to another shipping company. We introduce an auction mechanism for the firm to select the partner and determine the sharing percentage. Acting as the auctioneer, the firm announces a certain percentage of capacity to a set of buyers. The payment …

Benchmarking And Evaluating The Comparative Efficiency Of Urban Paratransit Systems In The United States: A Data Envelopment Analysis Approach, Hokey Min, Thomas E. Lambert

Faculty and Staff Scholarship

The Americans with Disabilities Act (ADA) of 1990 encouraged public transit authorities to reassess the way they serve aging populations and physically handicapped individuals requiring door-to-door services. As the demand for paratransit services rose dramatically the last few years due to a growing number of aging baby-boomers and injured Iraq-Afghanistan War veterans, many public transit authorities have been faced with the dilemma of meeting the growing demand while controlling costs in times of ongoing budget crises. To help public transit authorities better cope with such a dilemma, this paper evaluates the comparative operating efficiency of 75 selected paratransit agencies in …

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 …

Avoiding Shipper/Consignee Double Payment Liability, Roger F. Huff

Journal of Transportation Management

The purpose of this article is neither to engage in an overly technical legal analysis nor to disparage motor carriers who bring “double liability” claims against financially viable shippers/consignees; after all the trucking company has performed a valuable service and is simply trying to be paid “once” for that service - even though the financially viable shipper or consignee may have to pay twice with the bankrupt/insolvent third party absconding. The purpose of this article is generally to provide some “front-end” practical suggestions to shippers/ consignees in how to avoid being in court on one of these claims in the …

A Longitudial Study Of Private Warehouse Investment Strategies, Jonathan W. Kohn, Michael A. Mcginnis, John E. Spillan

Journal of Transportation Management

This article revisits private warehouse investment decision making, a topic previously examined in 1989 by McGinnis, Kohn, and Myers (1990). Since then there has been a substantial amount of discussion regarding the scope and nature of logistics /supply chain management. In particular the roles of private, contract, and public warehousing has been discussed, increased emphasis on financial performance and strategic decision making may have altered the criteria for investment decisions in private warehousing, increased coordination of supply chains may have altered the relative importance of private, contract, and private warehousing, and increasing emphasis on controlling inventory investment may have shifted …

A Triadic View Of Truck Driver Satisfaction, Stephen A. Lemay, Zachary Williams, Michael Carver

Journal of Transportation Management

In this research, the authors surveyed three groups concerning job satisfaction: experienced drivers, new drivers, and managers. Statistical tests were conducted using a sample of 196 new drivers, 145 experienced drivers, and 59 managers from a large TL firm based in the U.S. The results suggest that many discrepancies exist on driver satisfaction among the three perspectives. In particular, new drivers provide managers with opportunities and challenges for satisfaction. Given the current state of the trucking industry, managers will likely benefit from approaching this segment of drivers differently to meet their expectations and keep them from leaving their firms.

Private Warehouse Investment Strategies In Small Versus Large Manufacturing Firms, John E. Spillan, Michael A. Mcginnis, Jonathan W. Kohn

Journal of Transportation Management

The research reported in this manuscript empirically compares the private warehouse investment strategies of small and large manufacturing firms. Mail surveys were administered to independent samples of small and large United States manufacturing firms. This research is based on a series of identically worded questions administered to both samples. Data was factor analyzed and cluster analyzed to identify three private warehouse investment strategies for small and large firms and two strategies for large firms. Analyses of three independent variables further evaluated differences in private warehouse investment strategies. Finally, the warehouse mix of small and of large firms was compared. This …

The Impact Of Hours-Of-Service Regulations On Transportation Productivity And Safety: A Summary Of Findings From The Literature, Hokey Min

Journal of Transportation Management

Since driver fatigue has known to be the primary cause of serious truck crashes, the Federal Motor Carrier Safety Administration (FMCSA) has attempted to implement new hours-of-service (HOS) regulations that aimed to promote safer driving environments. The new HOS regulations effective on October T‘ of2005, however, may lead to substantial cost increases for the trucking industry which will in turn hurt shippers and ultimately customers. For instance, motor carriers may need to hire additional drivers to comply with new HOS regulations requiring that drivers be placed out of service until they accumulated enough off-duty time. In particular, off-duty breaks required …

Roles And Capabilities Of The Retail Supply Chain Organization, C. Clifford Defee, Wesley S. Randall, Brian J. Gibson

Journal of Transportation Management

Supply chain management (SCM) has become a critical strategic function in recent years. Research in the discipline has been focused toward the upstream side of the supply chain on functions such as warehousing, transportation, procurement and production. As power has shifted downstream toward retailers and their customers, SCM research has been slow to respond. This represents a significant gap, and a significant opportunity. Retailers face challenges that differ from those found in upstream suppliers and manufacturers. We present findings from a study of senior supply chain executives in the retail industry that focuses on the supply chain challenges of greatest …

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

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).

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 ± …
