Table 2 Sensitivity analysis 1 and 2 simulating breeding schemes with 0, 15, 30 and 45% of birds in C (P0, P15, P30 and P45), using 8 (H8) or 10 (H10) offspring per hen hatched for phenotype testing, and allocating 15, 30, 45 and 60% of total genotyping to birds in C (GC15, GC30, GC45 and GC60)

From: Benefits of testing in both bio-secure and production environments in genomic selection breeding programs for commercial broiler chicken

Scenario

Total number of birds hatched for phenotyping

Total number of genotyped birds

Number of birds moved to C (% of birds hatched)

Number of birds in C genotyped (% of total genotyping)
