Research ArticleOpen accessPhrase in the titleCorpus Luteum Morphology and Function After Timed Artificial Insemination (TAI) in Nelore Heifers Supplemented with Sunflower Seed in their DietsGabriel Molinari de Mattos, Beatriz de Moraes Ropelli, Claudia Maria Bertan Membrive et al.The dietary Polyunsaturated Fatty Acids (PUFA) supplementation, before the Timed Artificial Insemination (TAI) protocol, may contribute to a reduction in embryonic mortality. In this context, we hypothesized that dietary supplementation with sunflower seed, before the TAI protocol, will promote an increase in the ovulatory Follicle Diameter (FD), with a consequent increase in the Corpus Luteum Diameter (CLD) and the plasma … …American Journal of Animal and Veterinary Sciences, Vol. 16, Issue 3 · 12 Jul 2021 · 7,053 accessesView PDF Cite
