Ovarian follicle count and plasma AMH concentration on Nelore and Angus heifers
(Wiley-Blackwell, 2012-08-01)
Ovarian follicle count and plasma AMH concentration on Nelore and Angus heifers
(Wiley-Blackwell, 2012-08-01)
Precocious fertility in Nelore heifers.
(Soc Study Reproduction, 2003-01-01)
Follicle populations and gene expression profiles of Nelore and Angus heifers with low and high ovarian follicle counts
(2019-02-01)
The number of antral follicles counted (AFC) by ultrasound is associated with fertility in cattle. Cows with higher follicle count (HFC) have higher performance in reproductive-assisted technologies than cows with lower ...
Corpus luteum morphology and function after timed artificial insemination (Tai) in nelore heifers supplemented with sunflower seed in their diets
(2021-01-01)
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 ...
A combination of nutrition and genetics is able to reduce age at puberty in Nelore heifers to below 18 months
(2018-03-01)
Nelore heifers usually begin their reproductive life at ≥24 months of age mainly due to suboptimal nutritional conditions and genetics. This study aimed to determine the effect of expected progeny difference (EPD) for age ...
Changes in luteinizing hormone secretion after estradiol treatment in prepubertal Nelore heifers
(2011-07-01)
Changes in luteinizing hormone (LH) secretion after 17β-estradiol (E 2) injection were evaluated during sexual maturation in 10 prepubertal Nelore heifers. Heifers were divided into 2 groups: intact (I) and ovariectomized ...
Changes in luteinizing hormone secretion after estradiol treatment in prepubertal Nelore heifers
(Canadian Vet Med Assoc, 2011-07-01)
Changes in luteinizing hormone (LH) secretion after 17 beta-estradiol (E-2) injection were evaluated during sexual maturation in 10 prepubertal Nelore heifers. Heifers were divided into 2 groups: intact (I) and ovariectomized ...
Effects of temperament on growth, plasma cortisol concentrations and puberty attainment in Nelore beef heifers
(2019-06-01)
Excitable temperament disrupts physiological events required for reproductive development in cattle, but no research has investigated the impacts of temperament on growth and puberty attainment in Bos indicus females. ...
