Llanes, A., Whisnant, C. S., Knox, W. B., & Farin, C. E. (2018, November 30). Domestic Animal Endocrinology.

By: A. Llanes n, C. Whisnant n, W. Knox n & C. Farin*

author keywords: Pregnancy; Artificial insemination; PSPB; Ovulation synchronization; Small ruminants
MeSH headings : Animals; Delayed-Action Preparations; Dinoprost / administration & dosage; Drug Delivery Systems / instrumentation; Enzyme-Linked Immunosorbent Assay / veterinary; Equipment Reuse / veterinary; Estrus Synchronization / methods; Female; Gestational Age; Goats / blood; Goats / physiology; Gonadotropin-Releasing Hormone / administration & dosage; Insemination, Artificial / methods; Insemination, Artificial / veterinary; Litter Size; Ovulation / physiology; Pregnancy; Pregnancy Outcome; Pregnancy-Specific beta 1-Glycoproteins / analysis; Progesterone / administration & dosage
topics (OpenAlex): Reproductive Physiology in Livestock; Genetic and phenotypic traits in livestock; Reproductive Biology and Fertility
TL;DR: Reuse of CIDRs, even with reuse extending for a total of 21 d, was as effective as new CIDR for synchronization of ovulation, and PSPB concentrations detected using a commercially available ELISA at Day 48 or 85 of gestation could distinguish does carrying single versus multiple fetuses.

MeSH headings : Age Factors; Amino Acid Sequence; Animals; Base Sequence; Blotting, Northern; Blotting, Western; Cell Communication; Connexin 43 / biosynthesis; DNA, Complementary / metabolism; Female; Granulosa Cells / metabolism; Immunohistochemistry; In Situ Hybridization; Molecular Sequence Data; Ovarian Follicle / metabolism; Ovary / metabolism; RNA, Messenger / metabolism; Reverse Transcriptase Polymerase Chain Reaction; Swine
topics (OpenAlex): Connexins and lens biology; Heat shock proteins research
TL;DR: Results indicate that substantial amounts of Cx43 are first expressed in granulosa cells following activation of follicular development and that this expression increases throughout follicular growth and maturation, and suggest an association between the enhancement of intercellular gap-junctional communication and onset of follicle growth.
