“…Moreover, increased melanocyte-stimulating hormone α (αMSH) connections to kisspeptin/neurokinin dynorphin (KNDy) neurons were observed. These findings collectively suggest that enhanced juvenile nutrition elevates metabolic hormone levels, influencing gene expression and neuronal projections, ultimately impacting KNDy and GnRH neurons 27 .…”

This experiment evaluated the influence of creep feeding supplementation on productive and reproductive performance and on serum metabolome profile in Nelore (Bos indicus) heifers. Female calves were assigned to treatments: Creep (n = 190), with ad libitum access to a nutritional supplement from 70 to 220 days after birth, or Control (n = 140), without supplementation. After weaning (Day 220), both groups followed the same pasture and nutritional management. Body weight (BW) and backfat thickness (BFAT) were measured over time. Blood samples were collected at 220 and 360 days for LC–MS/MS targeted metabolomics. On day 408, during the synchronization timed artificial insemination (TAI) protocol, reproductive status (RS: diameter of uterine horn and largest follicle, and presence of CL) was assessed. Creep feeding increased BW and BFAT at weaning, but no differences in BW, BFAT, or RS after weaning were observed. Nonetheless, the pregnancy per AI (P/AI) for 1st service was 28.9% higher in the Creep group. On day 220, 11 significant metabolites influenced five metabolic pathways: Glucose-alanine cycle, alanine, glutathione, phenylalanine and tyrosine metabolism, and urea cycle. On day 360, 14 significant metabolites influenced eight metabolic pathways: Malate-aspartate shuttle, arginine and proline metabolism, urea cycle, aspartate, beta-alanine, glutamate metabolism, ammonia recycling and citric acid cycle. In conclusion, creep feeding supplementation improved calf performance and induced metabolic changes at weaning and 360 days of age. Although heifers had similar productive performance and reproductive status, when submitted to TAI, those supplemented with creep feeding had greater P/AI.

Selecting viable fully grown germinal and matured oocytes were positively effect on further embryonic development and live birth. The use of feed and hormonal supplementation and biotechnologies to enhance oocyte competence was evaluated. In addition, the oocytes were selected based on ovarian follicular stage, follicles and oocytes morphology, follicular fluid characters and gene expression. Changes were obtained in oocyte maturation, fertilization and further embryo cleavage and development over selecting viable oocytes. The larger follicle diameter, the translucent follicle and the higher blood supply the higher developmental competence of resulting oocytes. The higher surrounding cumulus cells and homogeneity of cytoplasm the higher developmental competence of oocytes. In addition, oocytes obtained during luteal stage compared to those obtained during follicular phase were highly or comparably developed to embryos. Furthermore, follicular fluid characters and gene expression might predict the embryonic developmental competence of oocytes in addition to their viable staining with brilliant cresyl blue. In conclusion, the characters of ovarian follicles, oocytes, follicular fluid and gene expression have significant implications on further oocyte developmental competence in different mammalian species.
