Sensitivity of nitrogen losses to interannual climate variation in subtropical hybrid dairy systems. [poster].
This study provides insights into N losses in hybrid dairy systems, emphasizing the importance of tailored strategies to minimize environmental impacts, considering the diverse spatiotemporal responses across different farmland uses and covers.
Efficient implementation of random regression models for dairy cattle genomic evaluations. [1141 - abstract].
ABSTRACT.- Random regression models (RRM) with ssGBLUP are used worldwide for dairy cattle genetic evaluations. This study aimed to improve the efficiency of implementing RRM with ssGBLUP for national dairy evaluations using the BLUPF90 software suite and to test a method to approximate reliabilities with genomic information.
Approximating reliabilities of indirect predictions based on SNP effects from large single-step genomic best linear unbiased prediction evaluations. [1520 - abstract].
ABSTRACT.- With the algorithm for proven and young (APY), the computing cost of ssGBLUP is linear with the number of noncore animals and cubic with the number of core, which is less than 20K for single breed and 50k for multibreed evaluations.
