| dc.description.abstract | The hypothesis that, intensive recording is needed for sustainable breeding programs in
developing countries in the face of climate change was tested.Using stochastic simulation, genetic
gain realised by breeding strategies using local and imported genetic materials under limited and
intensive recording in the local population was compared. Local breeding strategy (LBS) was
within breed selection based on local breeding goal. Imported strategies were admixture
conventional (ACS) and organic (AOS). They involved importationof semen from conventional
(ACS) and organic (AOS) breeding programs in developed countries to inseminate local sows. All
candidates in ACS and AOS were recorded for all traits in the index. Only 0.25% of the candidates
in LBS were recorded under limited recording. Thereafter, intensity of recording in LBS was
increased from 0.25-100%. With limited recording, LBS realised genetic gain of €13.87 compared
to €44.89 and 55.59 for ACS and AOS, respectively. The LBS, however, outperformed ACS and
AOS as intensity of recording increased. At 20% recording LBS realised 49 and 37%more genetic
gain than ACS and AOS, respectively. The LBS realised genetic gain of €142.09, compared to
€56.55 and 70.75 for ACS and AOS, respectively, when all candidates were recorded.These
findings confirm that intensive recording would be required to sustain the local breeding programs
and make the within breed selection attractive as an intervention strategy to climate change.
Intensive recording could be realised by creating awareness among farmers on importance of
records in farm management and adoption of new technologies likegenomic selection. | en_US |
