The Long Haul: Risks Associated With Livestock Transport, Michael Greger

Agribusiness Collection

The Food and Agriculture Organization (FAO) of the United Nations describes live animal transport as “ideally suited for spreading disease,” given that animals may originate from different herds or flocks and are “confined together for long periods in a poorly ventilated stressful environment.” Given the associated “serious animal and public health problems,” the Federation of Veterinarians of Europe has called for the replacement of the long-distance transportation of live animals for slaughter as much as possible to a “carcass-only trade.”

In the United States, more than 50 million live cattle, sheep, and pigs and an unknown number of the more …

Acute Stress Induced By The Preslaughter Use Of Electric Prodders Causes Tougher Beef Meat, R. D. Warner, D. M. Ferguson, J. J. Cottrell, B. W. Knee

Slaughter and Slaughtering Practices Collection

Adrenergic activation and hormone release preslaughter is an inevitable outcome of the systems used to move cattle to slaughter. The aim of this experiment was to investigate the effects of acute preslaughter stress in beef cattle on postmortem muscle metabolism and the meat quality, including consumer-assessed eating quality. Eighty-four cattle were used on three separate days, with ‘mobs’ of four cattle allocated to either a ‘control’ (no electric goads used preslaughter) or a ‘stress’ (six prods given with an electric goad over 5–10 min) treatment at 15 min preslaughter. Cattle undergoing the ‘stress’ treatment had higher plasma lactate at slaughter. …

Influence Of Free-Stall Base On Tarsal Joint Lesions And Hygiene In Dairy Cows, W. K. Fulwider, T. Grandin, D. J. Garrick, T. E. Engle, W. D. Lamm, N. L. Dalsted, B. E. Rollin

Housing and Confinement of Farm Animals Collection

The objective was to quantify the incidence of tarsal lesions and level of hygiene by stall bed type. Cows were scored on 100 dairies from Wisconsin, Minnesota, Indiana, Iowa, and New York in the fall and winter. Thirty-eight dairies used rubber-filled mattresses (RFM), 27 had sand beds, 29 had waterbeds, and 6 used compost packs (CPk). Stocking density, stall dimensions, bedding amount, bedding frequency, and type of bedding were recorded. One pen of early-lactation multiparous cows on each dairy was scored based on injury of the tarsal joints at the lateral and medial surfaces and tuber calcis at the dorsal, …

Fish Behaviour And Welfare, Lynne U. Sneddon

Ethology Collection

Fish are farmed intensively in aquaculture which is an economic necessity to provide large quantities for the food industry yet many species’ normal behaviours may be impaired by the nature of intensive aquaculture. Recommendations have suggested that for optimum welfare, animals should be able to express their natural suite of behaviours. Confining large migratory species such as salmonids to relatively small tanks or cages means they are unable to perform the extensive migrations performed by their wild counterparts so are these fish frustrated? When considering why salmonids migrate, their motivation is to find food yet if they are well fed …

Carcass Composition And Meat Quality Of Three Different Iberian × Duroc Genotype Pigs, Rosario Ramírez, Ramon Cava

Slaughter and Slaughtering Practices Collection

Carcass composition and meat quality of Longissimus dorsi (LD) and Biceps femoris (BF) muscles from three different Iberian × Duroc genotype pigs were studied: GEN1: ♂ Iberian × ♀ Duroc1; GEN2: ♂ Duroc1 × ♀ Iberian; GEN3: ♂ Duroc2 × ♀ Iberian. Duroc1 (DU1) were selected for the manufacture of dry-cured meat products while Duroc2 (DU2) were pigs selected for meat production, with high percentages of meat cuts and low carcass fat. Genotype had a significant effect on the differences found while sex had not. GEN2 showed the highest weights at days 180 and 238 of weaning and the highest …

The Welfare Of Animals In The Meat, Egg, And Dairy Industries

Agribusiness Reports

Each year in the United States, approximately 11 billion animals are raised and killed for meat, eggs, and milk. These farm animals—sentient, complex, and capable of feeling pain and frustration, joy and excitement—are viewed by industrialized agriculture as commodities and suffer myriad assaults to their physical, mental, and emotional well-being, typically denied the ability to engage in their species-specific behavioral needs. Despite the routine abuses they endure, no federal law protects animals from cruelty on the farm, and the majority of states exempt customary agricultural practices—no matter how abusive—from the scope of their animal cruelty statutes. The treatment of farm …

Welfare Issues With Selective Breeding Of Egg-Laying Hens For Productivity

Agribusiness Reports

Today’s commercial laying hens have been selectively bred to produce more than 250 eggs per year. This unnaturally high level of productivity is metabolically taxing, often causing hens to suffer from “production diseases,” including osteoporosis and accompanying bone fractures, and can lead to reproductive disorders. Research suggests that the problem of osteoporosis may be worsening, possibly due to industry’s continuous push toward maximizing productivity. For decades, economic considerations have been valued and emphasized over the welfare of individual birds. An immediate change in priorities is needed to aggressively address welfare problems associated with selective breeding for egg production.

Farm Animal Welfare: In Legislatures, Corporate Boardrooms, And Private Kitchens, Andrea Gavinelli, Miyun Park

State of the Animals 2007

According to the Food and Agriculture Organization of the United Nations, globally, approximately 56 billion land animals—including nearly 48 billion broiler chickens— are slaughtered for human consumption in a single year (Food and Agriculture Organization of the United Nations 2004), in addition to an untold number of aquatic animals. The numbers of individual animals raised and killed by the meat, egg, and dairy industries far surpass the number of animals with whom human beings have any other relationship—whether they be those seen as fabric, target practice, test tubes, companions, or sideshow spectacles.

Canada’S Commercial Seal Hunt, Rebecca Aldsworth, Stephen Harris

State of the Animals 2007

Like efforts to end the commercial hunting of whales, the campaign to stop the slaughter of seals in Canada has become a major focus for animal and environment protection groups and governments the world over. For decades the face of the harp seal pup has been a symbol—to many, the symbol—of environment and animal advocacy. But as much as the campaign to save the seals has become an icon for those who would protect wildlife, the campaign to continue the hunt has become a focus for those who would block the progress of the animal protection and environmental movements.

Effect Of Stall Base Type On Herd Health, Costs, And Producer Satisfaction, W. K. Fulwider, T. Grandin, D. J. Garrick, T. E. Engle, W. D. Lamm, N. L. Dalsted, B. E. Rollin

Housing and Confinement of Farm Animals Collection

The objective of this field study was to compare effect of stall base on herd health, stall maintenance, bedding cost, and producer satisfaction. Ninety-one dairies visited during a 4-mo period starting October 14, 2005 included 33 rubber-filled mattress (RFM), 27 sand, and 31 waterbed (WB) dairies. In this study, percent culled was higher for RFM (P = 0.001) and sand (P = 0.06) than WB stall base dairies. Percent of cows in fourth lactation or greater was higher on WB than either RFM (P = 0.01) or sand (P = 0.02) dairies. There was no difference between base types for …

‘Concentration Camps For Lost And Stolen Pets’: Stan Wayman’S Life Photo Essay And The Animal Welfare Act, Bernard Unti

Laws and Legislation Collection

In the 1960s, LIFE was America's single most important general weekly magazine, its photo-essay formula catering to a middle class constituency of millions. By the halfway point of that tumultuous decade, readers were accustomed to seeing searing and unpleasant images of a changing nation, one racked by civil unrest and entangled in a bloody war in Southeast Asia. But when LIFE's February 4, 1966 issue landed on newsstands and in mailboxes across the United States, with the cover's warning "YOUR DOG IS IN CRUEL DANGER," tens of millions of readers became acquainted for the first time with another kind of …
