Economic values in broiler breeding
Poultry Science, 1998 The objectives of this study were to derive economic values in broiler breeding and to determine their relationship with production circumstances. Economic values were derived using a deterministic economic model based on profit equations with a fixed amount of broiler meat output of the production system.

Multibreed analysis by splitting the breeding values [PDF]
Genetics Selection Evolution, 2006 Abstract An equivalent model for multibreed variance covariance estimation is presented. It considers the additive case including or not the segregation variances. The model is based on splitting the additive genetic values in several independent parts depending on their genetic origin.

ADAPTIVE CAPACITY AND BREEDING VALUE OF VEGETABLE VARIETIES OF PEAS COLLECTION
Овощи России, 2015 Adaptive properties and selection value of vegetable pea collection based on «seed weight per plant» have been studied. The genotypes with high total and specific adaptive capacity, relative stability, and breeding value for multiple purposes have been ...

Animal, 2015 Estimated breeding values (EBVs) and genomic enhanced breeding values (GEBVs) for milk production of young genotyped Holstein bulls were predicted using a conventional BLUP - Animal Model, a method fitting regression coefficients for loci (RRBLUP), a method utilizing the realized genomic relationship matrix (GBLUP), by a single-step procedure (ssGBLUP)

FEATURES OF BREEDING VALUE INHERITANCE SIRES OF HOLSTEIN BREED
Animal Breeding and Genetics, 2021 In our studies, the phenotypic manifestation of the additive form of inheritance of breeding value by milk yield (intermediate and parental dominance) was in 334 (82.2%) bulls, and non-additive form (over-dominance and regression) – in 72 (17.8%) including: over-dominance in 55 (13.5%) and regression in 17 heads (4.2%).

Estimation of the breeding value of sport horses in the Czech Republic
Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2004 The performance of 10671 horses in 10911 sport competitions was used to estimate the breeding value of the population of the Czech warm-blooded horses using the Best Linear Unibased Prediction method.

Estimation of prediction error variances via Monte Carlo sampling methods using different formulations of the prediction error variance [PDF]
, 2009 peer-reviewedCalculation of the exact prediction error variance covariance matrix is often computationally too demanding, which limits its application in REML algorithms, the calculation of accuracies of estimated breeding values and the control of ...
