PigEV – a new tool to derive economic values for pigs
نویسندگان
چکیده
The breeding objective defines the selection emphasis placed on individual traits based on the economic importance of each trait. In PIGBLUP, the $Index defines the breeding objective based on the profit function developed by Stewart et al. (1990). The profit function was based on two main equations quantifying a sow herd sub-objective (SHSO) and a growing-finishing subobjective (GFSO). Information required in the PIGBLUP $Index module included economic inputs outlining payment details and cost structures, performance levels in key characteristics of pig production and marketing weighting as outlined by Long (1991) during an earlier AGBU Pig Genetics Workshop.

Economic weights for performance and survival traits of growing pigs.
The objective of this paper was to derive economic weights for performance and survival traits of growing pigs including feed conversion ratio (FCR), daily feed intake (DFI), ADG, postweaning survival of the growing pig (SG), and carcass fat depth at the P2 site (CFD). An independent model was developed for each trait to derive economic values directly based on a typical Australian production s...
متن کاملEconomic values for meat quality traits in pigs.
The aim for this study was to derive economic values for meat quality traits. Meat quality experts from 10 slaughter and retail companies in Switzerland were asked to give an interview in which they indicated their willingness to pay different prices for carcasses from different quality classes. Economic values for the seven meat quality traits color (L*), drip loss, intramuscular fat content, ...
متن کاملEstimation of Economic Values for Fertility, Stillbirth and Milk Production Traits in Iranian Holstein Dairy Cows
The objective of present study was to derive the economic values for number of inseminations to conception, calving interval, milk yield and stillbirth, using economic data of 10 Iranian Holstein herds. The economic values were derived by using the profit function methods and differentiating a profit equation with respect to the traits of interest. The cow fertility costs herd amortization or r...
متن کاملDeveloping A New Operation-Economic Framework for Irrigation Networks without Water Market
This study focused on proposing a new operational perspective within main and lateral irrigation canals based on the economic value of water. To achieve this objective, the operation-economic framework offered in this study consisted of two main components of the PMP model and Operation model. The estimated economic values of water in different regions of the network were employed as the starti...
متن کاملTherapeutic analysis of organic acids on experimental dermatophytosis in guinea pigs
The purpose of this study was to determine the therapeutic efficacy of citric and tartaric acids on experimental dermatophytosis in guinea pigs. In this study, the susceptibility of Trichophyton mentagrophytes var. mentagrophytes to citric and tartaric acids was assessed using the macrodilution broth method. In the animal experiments, a cream consisting of the mixed acids was topically applied ...
