“…Amer et al (1994b) argued that the optimum endpoints are not constant across genotypes. Using neoclassical production economics theory, the profit maximizing level of backfat thickness at slaughter depended on breed and sex and ranged between 5.9 mm to 11.8 mm for common beef cattle breeds in Canada.…”

“…In practice, the results will not differ between the two approaches when the underlying model of the production system and its primary constraints are the same. Using the neoclassical production economics approach, Amer et al (1994b) reported the economic value for dressing percentage in a Canadian feedlot enterprise to be $8.40 per animal per 1% of the mean. Here, the absolute economic value for dressing percentage ranged from $8.59 to $9.44 per animal per 1% of the mean, depending on whether inputs (range or purchased feed) or output (beef sold) was fixed.…”

“…The range of economic values obtained for practical examples of production and marketing circumstances has not been determined for beef production systems. Economic values have previously been reported for beef production systems (Simm et al 1986;Bourdon and Brinks 1987;Ponzoni and Newman 1989;Newman et al 1992;Kolstad 1993;Amer et al 1994b;MacNeil et al 1994), but few results are directly comparable. The marketing and production systems and the assumptions employed all vary between studies.…”

Koots, K. R. and Gibson, J. P. 1998. Effects of production and marketing circumstances on economic values for beef production traits. Can. J. Anim. Sci. 78: 47-55. The effect of altering production and marketing circumstances on economic values is quantified for a complete beef production system. Absolute and relative economic values were found to vary substantially with large, but realistic fluctuations in prices and costs. In addition, several examples of different management and different genotypes gave markedly different economic values than in the base situation. Also investigated were the effects of rescaling the enterprise to accommodate three alternative limitations; fixed feed available from pasture, fixed dollars available for feed or fixed amount of beef produced. The effects of rescaling were highly dependent on whether or not fixed costs were accounted for. When fixed costs were ignored (corresponding to a small positive profit) the economic value for mature size decreased while that for fertility increased, but other traits were largely unaffected by rescaling. Overall, production circumstances that reduced survival and fertility yielded the largest changes to economic values.

“…More complex systems are better described by computer modelling (Bourdon & Brinks, 1987;Lamb et al, 1992;Wilton et al, 2002). Amer et al (1994b) used bioeconomic models to derive economic values for a limited number of traits in particular segments of the production system. These ignore the reality that animals must perform in all segments and levels of a production system.…”

The purpose of this article is to review the development of breeding objectives in beef cattle breeding and the derivation of economic values. There seems to be general consensus that definition of breeding objectives should be the primary step in the design of structured breeding programs. Development of the breeding objective can be described in terms of the following phases: specification of the breeding, production and marketing system, identification of sources of income and expense in commercial herds, determination of biological traits influencing income and expense, derivation of economic values, choice of selection criteria, and estimation of phenotypic and genetic parameters. The modelling methods to derive economic weights can be divided into simulation, dynamic programming and profit functions.

“…Using alternative types of model farms, the economic value of genetic traits can also be estimated for alternative production environments. Yet another application to the comparison beef cattle genotypes for feedlot traits has been provided by Amer et al (1994).…”

Summary The decline in biodiversity of farm animal genetic resources (AnGR) has come to the forefront of concern in the discussion of animal conservation and breeding programmes. To improve decision‐making regarding conservation and breeding programmes, a number of evaluation techniques of farm AnGR are available. This paper presents an overview of the different values associated to AnGR and of the techniques for their measurement being employed in the economic literature. Those include linear programming and farm simulation models, dynamic models estimating the value of research and development and econometric models estimating the demand for breed characteristics. While farm programming and simulation models are fairly well developed, they do have large data requirements. Alternatively, contingent valuation methods are available, in particular when the goal is to capture non‐market values embedded in breeds.
