breeding value


Also found in: Acronyms.

breeding value

the (economic) worth of an individual's GENOTYPE, as judged by the average performance of its offspring. From the size of the breeding value it is possible to choose suitable parents for future crosses.

Direct breeding value of average daily gain, stayability, and number of piglets born alive at the first parity: The estimated genetic correlation coefficient between DBV of ADG and STAY was significantly negative (-0.30 [+ or -] 0.13), suggesting that animals with high genetic potential for ADG could have a lower STAY.
To generate simulated populations, a Fortran-language simulator was developed using the (co)variances of the breeding values and the productive and reproductive rates and means obtained from the real populations, composed of the animals selected in the year 2014 (Generation 0).
Although this technology has been used in dairy production studies for the genetic analysis of test day models (Legarra et al., 2004; Yilmaz et al., 2011), The RRM allow getting breeding values for milk yield at any day of lactation in a continuous manner or for functions of lactation curve, instead of finite dimensional models that only give punctual predictions of breeding values.
These methods are sufficient for diagnosis of severe anomaly at an early stage on the basis of it is possible to assess the future breeding value of each individual to ensure and maintain the animal's welfare by means of starting the treatment or exclusion of severely affected animals from further breeding.
The average breeding value of foreground traits were increased to -4.4627, -4.0563, -1.9749, 0.6810, 2.4754 and 3.3358 under 0.95/0.05.
The overall trend was static and this was similar with the results presented by Hussain (2006) who reported that breeding value for rams ranged from -0.447 to 0.216 for birth weight; -1.512 to 2.859 for weaning weight, -1.686 to 2.089 for yearling weight.
One possibility to overcome this specific limitation of using crossbred animal phenotypic data would be to use GW-MAS to estimate the breeding value of individuals in the purebred lines using combined phenotypic and genotypic information collected in crossbred animal samples and just genotypic data in the purebred.
The earlier mentioned model was also used to calculate breeding values for the parents and progeny.
The section of dealing with the variation in breeding populations (81 pages; three chapters) begins with partitioning phenotypic, genetic, and environmental variance components and further describes genetic components of variance such as additive, dominance, and epistasis in terms of breeding values and allele frequencies.
This index is based on `estimated breeding values' (EBVs) for the number of kittens weaned and high growth rate after weaning (see story on page 31).
where [g.sub.i] = [[Sigma].sub.j] [b.sub.j] [x.sub.ij] is the called the breeding value or additive genetic value.
