Oxytocin synthesis and release by the bovine corpus luteum

Creator:: Abdelgadir, Salaheldin Eltigani
Abstract:: Four experiments were conducted to determine oxytocin concen tration of bovine luteal tissue at different stages of the estrous cycle and to study the effects of prostaglandins F₂α (PGF₂α), E₂ (PGE₂), luteinizing hormone (LH), cycloheximide, colchicine and cytochalasin B on oxytocin synthesis and release in vitro. In experiment 1, luteal...

Litter productivity at first and second parity by gilts mated at different weights at first or second estrus

Creator:: Tachasirinugune, Sommai
Abstract:: Purebred Yorkshire gilts with weights ranging from 70 to 105 kilograms were moved from a total-confinement rearing unit to a total-confinement brood stock unit where approximately ten gilts per pen were mixed to provide new penmates. Each gilt was thus exposed to an unfamiliar environment and to foreign penmates along...

Comparison of Canine Spermatozoa Motility, Morphology, and RNA Integrity Using Three Different Cell Purification Solutions

Creator:: Hegedus, Rachel M.
Abstract:: Transcriptome gene expression studies of sperm RNA have been utilized in a variety of different species to investigate causes of male infertility. Previous research investigators have optimized cell separation and RNA isolation techniques for each species of interest. To date, no study has been completed for dogs. The objective of...

Effect of nutrition on reproductive performance of young female mink

Creator:: Polonen, Ilpo Juhani
Abstract:: Two distinct experiments were conducted. Experiment 1 was conducted to investigate the effects of nutritional conditioning and flushing as a means of improving reproductive performance of female mink. In Exp. 2, vegetable oil and corn syrup were fed during lactation to ascertain whether this nutritional regimen would improve growth of...

Evaluating pollinator populations and lamb productivity from simple, diverse, and legume pastures in a dual use pasture system

Creator:: Caudillo, Mia C.
Abstract:: Dual use pasture systems, sometimes referred to as dual purpose pasture systems, take advantage of the land being used to maximize multiple outputs from a single area. Developing a system to support both production of grazing livestock as well as pollinator health is of increasing importance in pasture-based farming systems....

Concerted actions of ovarian steroids and prostaglandin F₂a on smooth muscle contractility of ovine and bovine uterine arteries

Creator:: Ford, Stephen Paul
Abstract:: The role of estradiol- 17β, progesterone and prostaglandin F₂α (PGF₂α) in altering contractility of uterine vascular smooth muscle was investigated. A segment of uterine artery (3. 5 cm) supplying each uterine horn of ewes and heifers were removed at necropsy and perfused with oxygenated Krebs Henseleit Solution prior to initiating...

The use of natural plant extracts as a feed additive to prevent laminitis in lactating dairy cows

Creator:: Pierson, Miranda L.
Abstract:: Two experiments were conducted looking at both acute and sub-acute laminitis. An acute nutritional induction model was used to examine whether blood profiles and gene expression are similar to other studies conducted using an endotoxin induction model. Twelve sheep were randomly assigned to three treatment groups which were control, 4-hour...
