DESCRIPTION:PhD Oral Defence of Bernard Ato Hagan\, Animal Science\n\nMost 
 livestock producers and breeders seek to maximize genetic gains for econom
 ically important traits and at the same time increase the rate at which ge
 netic gains are achieved. Genetic gains are only brought about by genetic 
 selection. Dairy producers in Canada\, however\, do not have appropriate t
 ools to monitor what selection and the amount of selection producers and A
 I organizations are making in their herds and studs\, respectively. Geneti
 c evaluations for Canadian Holstein\, Ayrshire\, Jersey\, and Brown Swiss 
 dairy cattle breeds were used to define and compute the realized genetic s
 election differentials (GSD) for 28 economically important traits and to i
 nvestigate generation intervals in the four dairy cattle populations along
  the 4-path selection model. The findings from this study indicate that ye
 ar of conception was the main environmental factor that was most important
  in the GSD realized in all four paths of selection (male-to-male\, female
 -to-male\, male-to-female\, and female-to-female)\, whilst there were cons
 iderable variations in the GSD realized among herds in all four dairy catt
 le populations.\n\nThe results from the analyses in this study have been u
 sed to develop a prototype software tool and visualization model to help d
 airy producers and advisors monitor the selection realized in their indivi
 dual dairy herds. This will enable dairy producers to determine whether th
 e selection they are making align with their breeding objectives. The conc
 ept of the developed software tool is applicable to all livestock species 
 for which genetic evaluations are routinely computed and published.\n\nEve
 ryone in the McGill community is welcome to attend a PhD Oral Defence. Ple
 ase join us in celebrating the accomplishments of our PhD candidates.\n\n
