Laughlin most broiler breeder farms are company owned and/or farming space is in short supply (and stocking densities are higher), the strategy would be to have 5% production at 23 weeks of age, with first light stimulation before 21 weeks. Breeder management strategies and techniques have evolved since the late 1950s, with some ideas originating in scientific studies gaining wide acceptance and many being modified through field experience. Some ideas, although theoretically promising, have failed to gain widespread use due to cost or practicality or the management strategy being followed in a specific region or time period.

However, moving from QTL to causal mutation (the quantitative trait nucleotide – QTN) is difficult and has only been successful in a few cases, such as for IGF2 in pigs and DGAT1 in cattle (Andersson and Georges, 2004). , 2004), which makes it possible to genotype individuals using genome-wide SNP assays containing over 20,000 SNPs per assay, will greatly contribute 32 P. Bijma and H. Bovenhuis to identifying QTNs. g. the callipyge mutation described by Takeda et al. (2006). This illustrates that even with the availability of the chicken genome sequence and genome-wide SNP assays the identification of QTNs is difficult.
