Special Issue Information

Dear Colleagues,

Reproductive success in cattle is a complex parameter that is affected by many factors such as genetic selection and reproductive physiology as well as nutritional management. It is known that the fertility of cows has decreased along with the great demands on milk production. Therefore, it is essential to achieve advances in reproductive management to reduce the incidence and effects of various problems that affect the reproductive efficiency of dairy cattle, such as the extended postpartum anovulatory period, poor heat detection, low pregnancy by insemination and high pregnancy loss. The aim of this Special Issue is to publish research articles or original reviews on advances in dairy cattle reproduction and nutrition management. Topics of interest include the adequate management and nutrition of transition period, postpartum health monitoring programs aimed at reducing reproductive illnesses and solid reproductive strategies, which include manipulation of the ovarian cycle to allow a higher insemination rate, embryo transfer programs, as well as the introduction of fertility traits in selection programs.

For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Animals is an international peer-reviewed open access semimonthly journal published by MDPI.

Abstract
The purpose of this study was to determine the link between insulin-like growth factor 1 (IGF-1), progesterone (PROG), non-esterified fatty acids (NEFAs), β-hydroxybutyrate (BHB), and glucose (GLU) and pregnancy probability after the first artificial insemination (AI) and during the first 100 days in [...] Read more.
The purpose of this study was to determine the link between insulin-like growth factor 1 (IGF-1), progesterone (PROG), non-esterified fatty acids (NEFAs), β-hydroxybutyrate (BHB), and glucose (GLU) and pregnancy probability after the first artificial insemination (AI) and during the first 100 days in milk (DIM), during the critical transition period. We determined levels of serum IGF-1, PROG, NEFA, BHB, and GLU in Holstein dairy cows via ELISA, using blood samples collected 7 days before parturition (DAP) until 21 days postparturition (DPP). The group was split into cows diagnosed pregnant at 100 DIM (PREG) and those that did not conceive at 100 and 150 DIM (NPREG). Serum IGF-1 and PROG median levels at 7 DAP were significantly higher in PREG vs. NPREG (p = 0.029), the only statistically significant differences across the subgroups. At 7 DAP, IGF-1 levels within the initial group showed a strong negative correlation with PROG (r = −0.693; p = 0.006), while for the PREG subgroup, the IGF-1 levels exhibited a very strong positive correlation with GLU (r = 0.860; p = 0.011) and NEFA (r = 0.872; p = 0.013). IGF-1 and PROG levels detected at 7 DAP may be useful to predict pregnancy at 100 DIM. The positive correlation of NEFA and GLU levels during the transition period demonstrates that the initial group is not in NEB; thus, the NEFA level was not a decisive factor for reproduction success.
