Economic values for production and functional traits in Valle del Belice dairy sheep using profit functions

Autor: D. O. Maizon, Valentina Riggio, Marco Tolone, Baldassare Portolano

A deterministic static model was used to estimate the economic values (EV) of production (MY, milk yield; BW, birth weight; and ADG, average daily gain) and functional traits (ASR, adult survival rate; LSR, lamb survival rate; FE, fertility; PR, prol

Bayesian reanalysis of a quantitative trait locus accounting for multiple environments by scaling in broilers

Autor: J B C H M, van Kaam, M C A M, Bink, D O, Maizon, J A M, van Arendonk, R L, Quaas

Publikováno v: Journal of animal science. 84(8)

A Bayesian method was developed to handle QTL analyses of multiple experimental data of outbred populations with heterogeneity of variance between sexes for all random effects. The method employed a scaled reduced animal model with random polygenic a
