Economic Values for Meat Quality Traits

چکیده

and Implications A method was developed to calculate economic values for pork quality traits for use in genetic selection. The method considers the normal variability of pork quality traits within a herd or population. The parameters required for this method are the mean, standard deviation, and range of the quality trait within the herd or population, and the relationship of the level of the quality trait with price received for pork at the consumer level. The method was applied to results from a consumer preference study of quality traits of pork loin that was conducted by the National Pork Producers Council. Resulting economic values of percentage of lipid (lipid%), Instron score, and ultimate pH were $.9112, $-.4040, and $-.3469, respectively, per kilogram of loin per unit increase in the trait. Results indicate that efforts to increase lipid% and to decrease Instron score can result in extra revenues for swine production. The sign of the economic value for ultimate pH was opposite to expectations, which is a reflection of the results of this specific consumer preference study. A second preference study is currently under way and its result will be used to reevaluate economic values. Alternative methods to select for quality traits, such as optimum linear indexes and indexes based on a quadratic aggregate genotype, were discussed.

Genetic parameters for carcass composition and pork quality estimated in a commercial production chain.

Breeding goals in pigs are subject to change and are directed much more toward retail carcass yield and meat quality because of the high economic value of these traits. The objective of this study was to estimate genetic parameters of growth, carcass, and meat quality traits. Carcass components included ham and loin weights as primal cuts, which were further dissected into boneless subprimal cu...

Economic Evaluation of Recording Meat Quality Traits from Pedigreed Animals

Before introducing a recording system for meat quality traits, the returns of this recording and the costs involved to obtain various measurements have to be compared. Some traits might be of high economic value, but on the other hand recording of these traits is also very costly. Recording of traits with low economical importance might be beneficial because of the low costs involved in obtaini...
