Antibiotics have been used by pig producers for several decades, and are now used routinely. This study documents the current productivity and economic impacts of the use of antibiotics for growth promotion (AGP) by pig grower/finishers at the farm level. We evaluate the impacts of an AGP ban, and use of AGP by all pig grower/finishers for 61S90 days (a more production-efficient level), using data from the National Animal Health Monitoring System Swine 2000 Survey. Findings indicate that pig productivity improves with AGP. Relative to current use, an AGP ban would decrease producer profits by $1,400 per 1,020-head barn, and profits would increase by $1,992 for each grower/finisher barn when AGP is fed for 61 to 90 days. There is increasing concern about...

Potential HPAI Shocks and Welfare Implications of Market Power in the U.S. Broiler Industry

Liang, Jing; Fabiosa, Jacinto F.; Jensen, Helen H.; Miller, Gay Y..

Recent outbreaks of highly pathogenic avian influenza (HPAI) in Asia, Europe, and Africa have caused severe impacts on the broiler sector through production losses, trade restrictions and negative shocks to demand. This study develops a multimarket econometric model that is the basis of simulations to assess the spread and market implications of a potential HPAI outbreak in U.S. broiler industry. It takes into account market power that might exist within the livestock and meat sectors and endogenizes the optimal production condition on the model system. The results imply that the HPAI shocks affect prices at different marketing levels unequally and change the price margins along the supply chain with the existence of market power. The change in the price...

Few farm-to-table analyses of the risk pathways for foodborne illnesses exist, and no such analysis exists for the case of salmonellosis and pork products. This paper presents a Monte Carlo simulation model of the US pork system and the transmission pathways of Salmonella. For the year 2000, we estimate the cost of illness attributable to porkborne Salmonella at $45.7 million, with an estimated 43,505 cases of salmonellosis attributable to pork occurring annually.

Production risk from live weight variation of market pigs has become a more important concern in U.S. swine production. Packers are concerned about the variation in carcass size because of the demand for standardized cuts and the use of automation in the slaughter process. Swine producers care about standardized pigs because of revenue implications and possible links to animal health and productivity. Pig size variation can be due to various condition and inputs including antibiotics. However, discussions on risk reduction from antibiotic use have generally not been considered. Our work extends previous studies by systematically examining the aspects of production risk reduction and highlights the potential results of banning antibiotics from a risk...

Based on a spatiotemporal hedonic farmland price model and county-level data in Illinois from 1979 to 1999, we examined the impact of swine production on farmland values. Our results show that, in addition to the conventional determinants of farmland values, an increase in swine production intensity has a negative relationship with farmland values while an increase in swine operation scale had a positive association with farmland values at the county level in Illinois. We also estimate the impact of changes in the Illinois swine industry over the period 1980-1999 on farmland values at the state level and find that changes in swine inventory and scale of swine operations have led to changes in farmland prices from $-10.56 to $62.96 per acre. In general, the...

PRODUCER INCENTIVES FOR ANTIBIOTIC USE IN U.S. PORK PRODUCTION

Antibiotics have been used in animal production for several decades. Antibiotics are used routinely now in pork production (NAHMS 2002). There is increasing concern about the use of antibiotics in animal production. There is no hard evidence supporting the link of antibiotic use in animals to observations of antibiotic resistance infections in people. Nonetheless a careful examination of the value of continued antibiotic use in agricultural, and in pork production in particular is warranted. Therefore, the objective of our study is to validate the productivity and economic impacts of antibiotic use for pig producers at the farm level. We use data from the NAHMS 2000 swine survey. We estimate the combined affects from antibiotics used for growth...

We combine econometric and financial analyses of the NAHMS 2000 Swine Survey data to examine whether evidence exists for reducing risk by using antibiotics for growth promotion (AGP) in the U.S. swine industry. A stochastic dominance analysis of alternative lengths of time (days) of AGP application reveals that AGP used in the range of 65—75 days is preferred by risk-averse producers. Risk is reduced and profits are increased from use of AGP. The combined impacts of increased average daily gain and decreased variability in pig live weight increase producer profits by $2.99 per pig marketed.

CHARACTERISTICS OF CONSUMERS DEMANDING AND THEIR WILLINGNESS TO PAY FOR CERTIFIED SAFER PORK

Miller, Gay Y.; Unnevehr, Laurian J..

A telephone survey of 609 Illinois households was conducted in spring 1999. Most consumers surveyed have concerns about pork safety. Concerns were greatest among households with children, lower incomes, older consumers, and Blacks. Lower consumption of pork was associated with higher concern. Consumers had more confidence in USDA certification of enhanced pork safety than in industry certification. Most consumers were willing to pay some price premium for a certified safer product. Those willing to pay more were more likely women, older consumers with incomes less than $70,000, who live in an urban household, and have concern about pork safety.

VARIABILITY IN GROWTH, PIG WEIGHTS AND HOG MARKETING DECISIONS

Variability in pig growth is an intrinsic characteristic of swine production. The optimal marketing strategies are identified to minimize the negative economic impact of variability for a typical all-in-all-out swine finishing facility using a recent pricing matrix and data featuring swine production in the Midwestern region. Our results show that compared with marketing all pigs from a 1,020 head barn on the same day, marketing pigs in six truckloads on different dates as groups of pigs grow to more optimal size significantly improves the profitability of production as variability increases. This finding is in line with recent producer response to new pricing matrices that prove stronger price incentives for marketing more uniform pigs. We also find that...

Public health experts are concerned about the diminishing efficacy of antibiotics. Some have called for a ban on growth-promoting antibiotics in animal agriculture. This study identifies the contribution of growth-promoting antibiotics in the grower/finisher phase of U.S. pork production. With National Animal Health Monitoring System swine data, relationships are estimated between growth-promoting antibiotic use and productivity. Results indicate improvements in average daily gain (0.5%), feed conversion ratio (1.1%), and mortality rate (reduced 0.22 percentage points); these productivity improvements translate into a profitability gain of $0.59 per pig marketed, or an improvement of 9% in net profits associated with growth promotion antibiotics.

AN ECONOMETRIC ANALYSIS OF THE ECONOMIC CONTRIBUTION OF SUBTHERAPEUTIC ANTIBIOTIC USE IN PORK PRODUCTION

Algozin, Kenneth A.; Miller, Gay Y.; McNamara, Paul E..

There is growing concern among public health experts regarding the diminishing efficacy of antimicrobial therapy in human and veterinary medicine, and some have called for a ban on subtherapeutic antibiotic use in pork production. This paper develops an econometric analysis to identify the economic contributions of subtherapeutic antibiotic use in swine production.

MANURE VALUE, PRICING SYSTEMS, AND SWINE PRODUCTION DECISIONS

Based on a swine producer's profit maximization model in which manure value and packers' live market weight pricing systems are considered, the optimal farm inventory and optimal hog market weight are simultaneously solved for scenarios generated from the combination of two crop rotations, two forms of manure storage, two levels of manure incorporation, and two nutrient application standards. First, our results suggest that manure value has a significant impact on the optimal farm inventory as well as on the profitability of an operation. The optimal size of operation identified is quite large and varies considerably among the scenarios. Our results indicate that shallow pit buildings with lagoons can support a larger operation scale and require less...

EVALUATION OF SWINE ODOR MANAGEMENT STRATEGIES IN A FUZZY MULTI-CRITERIA DECISION ENVIRONMENT

Palavras-chave: Livestock Production/Industries.

Ano: 2003

URL: http://purl.umn.edu/22233

The paper evaluates swine odor management strategies using the fuzzy extension of the Analytical Hierarchy Process (AHP), which is a multiple criteria decision making approach based on fuzzy scales. The evaluation is conducted using data from our cost effectiveness study of odor management strategies and our on farm studies relating odor to various management practices. These strategies include manual oil sprinkling, automatic oil sprinkling, wet scrubber, diffusion-coagulation-separation (DCS) deduster, pelleting feed, and draining shallow pit weekly. The criteria employed to evaluate the strategies are odor reduction efficiency, costs, nutrients in manure, and other benefits. Two producer profiles are considered: (a) producers who are pressured to...

In this paper, statistical and economic analyses are used in identifying, analyzing, and modeling the relationships among citizen complaints, swine production and community characteristics, EPA inspections, and regulatory violations. The primary results of this research include assessments of factors that affect citizen complaints and factors that affect the probability of regulatory violations. In addition, the analyses also provide statistical results of a comparison of the efficiencies of different types of site inspections in regulatory violation detection. Our results provide information valuable for understanding issues surrounding the development of the swine production industry and local communities.

THE INFLUENCE OF SALMONELLA IN PIGS PRE-HARVEST ON SALMONELLA HUMAN HEALTH COSTS AND RISK FROM PORK

Salmonellosis in people is a costly disease, much of it occurring because of food associated exposure. We develop a farm-to-fork model which estimates the pork associated Salmonella risk and human health costs. This analysis focuses on the components of the pork production chain up to the point of producing a chilled pork carcass. Sensitivity and scenario analysis show that changes that occur in Salmonella status during processing are substantially more important for human health risk and have a higher benefit/cost ratio for application of strategies that control Salmonella compared with on-farm strategies.
