    An experimental test of the efficiency of family selection in chickens (1980)
    Springer
    Theoretical and applied genetics 56 (1980), S. 5-9 
    Details
    ISSN: 1432-2242
    Keywords: Genetics ; Poultry ; Family selection ; Individual selection
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Summary Responses to single trait selection on individual phenotype and sire-family mean phenotype for survivor's egg weight and rate of lay were measured for a single generation in 13 replicates. Each replicate-selection criterion-trait subclass consisted of eight sire families or 72 females measured and was reproduced from the best 25% of the families or individuals. The realized heritability of egg weight was 0.39 and that of rate of lay was 0.31, both of which were significantly greater than zero but not significantly different from the predicted values based on halfsib correlations in the base population. The standardized response to sire-family selection was less than the response to individual selection for both traits and the difference was significant for rate of lay (0.10; 0.31) but not for egg weight (0.22; 0.39). The predicted responses to sire-family selection were less than those for individual selection for both traits, and the observed responses to sire-family selection were not significantly different from the predicted values for either trait. These experimental results do not disagree with the theoretical expectations of the relative efficiencies of individual and sire-family selection.

    Genetic gains from reciprocal recurrent and within-line selection for egg production in the fowl (1974)
    Springer
    Theoretical and applied genetics 44 (1974), S. 364-372 
    Details
    ISSN: 1432-2242
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Summary Selection for survivors percent egg production from first egg to 40 weeks of age was conducted for six generations. Within-line selection (WLS) on the basis of an index of individual records plus sire family and dam family means was compared with reciprocal recurrent selection (RRS) based on sire family selection among cross progeny. Genetically heterogeneous synthetic populations, the Cornell Control and the Purdue Pool strains were used. The responses to WLS (3.84 °) and RRS (2.57 °) were both significantly greater than zero, but were not significantly different from each other. Nevertheless, the responses were proportional to their predicted values (.363 vs. 340). The advantage of WLS was due to the mechanics of selection resulting in slightly greater selection intensity and an increased correlation between the criterion of selection and the trait being improved. On the contrary, the RRS method had a slightly larger realized heritability as would be expected in the presence of non-additive genetic variance. Four of five pure-lines selected under both methods had statistically significant declines in performance due to inbreeding depression effects. All of the results observed are comparable with known genetic theory. Some problems in comparing genetic gains from different selection methods or selection criteria are discussed.

    A replicated single generation test of a restricted selections index in poultry (1978)
    Springer
    Theoretical and applied genetics 52 (1978), S. 227-231 
    Details
    ISSN: 1432-2242
    Keywords: Poultry ; Genetics ; Index selection ; Egg mass
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Summary Predicted and realized responses in a single generation of mass selection for an index and for its component traits were compared. The index included the log transformed traits determining egg mass in chickens to 40 weeks of age (days tested from sexual maturity, egg weight, rate of lay). The index was restricted to allow no increase in log days tested. Other traits measured were egg mass, age at first egg, egg weight, rate of lay, number of eggs and body weight. When averaged over replicates, realized and predicted responses were in close agreement for index values and for the component traits. Significant corresponding correlated responses were obtained for egg mass and weight. The restricted trait, log days tested, and the correlated trait age at first egg did not change. Egg mass was increased solely through change in egg weight.
