Cellular signaling relies on macromolecules to transduce stimuli information into conformational changes (Changeux and Edelstein, 2005). The mechanisms by which macromolecules accomplish this feat are often allosteric: a small stimulus applied at one area of the macromolecule regulates behavior at locations structurally distant from the active site of stimulation. A detailed and mechanistic und...

Background: The objectives of a series of studies undertaken was to improve farm animal reproductive efficiency in terms of embryo production efficiency, conception rate and litter size by immunoneutralization of inhibin in conjunction with other conventional reproductive techniques. Materials and Methods: A recombinant porcine inhibin alpha-subunit mature peptide was produced by mass scale and...

this prospective longitudinal study deals with the associations between digital disorders and reproduction indices in dairy cattle on a farm in the vicinity of tehran. it was carried out on 225 postparturient holstein heifers. the evaluation of lameness due to digital disorders on postpartum period of heifers were done and after diagnosis of lameness (based on a 5 points lameness scoring system...

Overall, 531 dairy cows were inseminated with the aim to study their reproductive performance following administration of GnRH analogue on different days of estrous cycle with different doses. These cows were divided into six treatment and one control group. Depending upon different treatment groups, Buserelin acetate was injected at a dose of 10.5 µg or 21.0 µg on different days (0, 5 or 12) o...

Background: The objective of this study was to assess the genetic and phenotypic parameters associated with success rate conception using 90-days non-return (NRR90F), Rate (CR) number insemination (INS) traits in service bull. Methods: A total 2590 including 1776 first time carried out during period 2018-2020 Gir cattle distributed semi-arid region RajasthanNRR90F CR were analysed as binary var...
