Abstract This study was carried out to estimate the heritability and genetic correlations between adjusted weights at 210 (W210) and 450 (W450) days of age, scrotal circumference adjusted at 365 (SC365) and 450 (SC450) days of age, age at first calving (AFC), probability of precocious calving (PPC), stayability (STAY), ribeye area (REA), subcutaneous backfat thickness (BF), and rump fat (RF) traits. The covariance components and genetic parameters for all traits but PPC and STAY were estimated considering a linear animal model, for the remaining traits a threshold animal model was used. The single-step genomic BLUP (ssGBLUP) procedure was used for all traits, and the correlation estimates were obtained by two-traits analysis. The heritability estimated by single-trait analysis were 0.21 ± 0.01, 0.43 ± 0.01, 0.47 ± 0.02, 0.52 ± 0.02, 0.11 ± 0.01, 0.12 (0.07?0.16), 0.37 (0.26?0.38), 0.33 ± 0.02, 0.17 ± 0.01 and 0.33 ± 0.02 for W210, W450, SC365, SC450, AFC, PPC, STAY, REA, BF and RF, respectively. Growth traits (W210 and W450) showed high (0.95) genetic correlation with one another, moderate (0.30 to 0.66) with REA and scrotal circumferences, and low (−0.07 to 0.20) with female reproductive traits (AFC, PPC, and STAY) and fat carcass indicator traits (BF and RF). Female reproductive traits displayed moderate (−0.29 to 0.52) genetic correlations with male reproductive traits, and varied from low to moderate (−0.02 to 0.35) with carcass traits. Additionally, carcass traits exhibited low to moderate (−0.02 to 0.48) genetic correlations with all traits, except for the genetic correlation between BF and RF (0.73). Hence, higher genetic gains by direct selection would be obtained for W450, SC365, SC450, STAY, REA, and RF. Selection to increase growth traits might increase carcass yield and scrotal circumference, and it would not affect carcass fat content, precocity, and cow longevity indicator traits. The results of this study encourage the use of PPC in Nelore cattle since the selection for such trait would improve the productivity and longevity of the cows. The inclusion of carcass quality indicator traits such as BF or RF in selection indices would increase the genetic gain for carcass grade, but it will require further studies to estimate the economic value of these traits.

Abstract: This study aimed to evaluate the effects of donor age on lipid metabolism during in
vitro maturation (IVM) of pigs cumulus?oocyte complexes (COCs). We evaluated
transcript levels of genes, the percentage of ooplasm occupied by lipid droplets (LD)
and evaluated DNA methylation in COCs from sows and prepubertal gilts. Transcript
levels of six genes (ACACA, ACSS2, FASN, FABP3, SLC27A4, PLIN2), which were
analyzed in cumulus cells (CCs), increased after 44 h of IVM in the sow group. In the
gilt group, only FASN expression increased, while NR3C1 expression decreased after
IVM. The measurement of LD in oocytes showed an accumulation of lipids in sow
oocytes during IVM, while gilt oocytes showed a decrease in LD. FABP3 and NR3C1
methylation patterns exhibited a demethylation pattern in CCs and oocytes from
gilts and sows and showed statistical differences between groups. CCs from sows
had a better capacity to change transcription levels of the major genes involved in
lipid metabolism during IVM than CCs from gilts. This difference may be involved
in accumulation of lipids, acquisition of competence, and maturation of enclosed
oocytes. Our results contribute to a better understanding of mechanisms involved in
lipid metabolism and acquisition of competence in porcine COCs. |
