Approaches for alleviating toxic effects of aflatoxin in lactating dairy cows and weanling pigs
(University of Missouri--Columbia, 2010)
Aflatoxin (AF) is a mycotoxin found in feed ingredients used in livestock diets including dairy cattle and pigs. Aflatoxin causes reduced performance, liver damage, increased prevalence of infectious disease, and secretion ...
Genetics in practice : applications of quantitative genetics to environment and educational pursuits
(University of Missouri--Columbia, 2018)
in consumption was due to a minimum of about 10-12 genes. Such a high number of genes with little information on architecture makes reliable phenotypic selection difficult. Ultimately, we determined the phenotype was lost in LB animals but about six genes were...
Mitigation of summertime boar infertility by evaporative and conductive cooling
(University of Missouri--Columbia, 2018)
[trademark] Temperature Implant, Data Sciences International; St. Paul, MN): one implanted between the peritoneum and the body wall (core temperature); the other sutured between the testicular tunics (testicular temperature). The initial selection for the most effective...
Determination of fat percentage using three different methods within marbling scores on beef longissimus muscle
(University of Missouri--Columbia, 2010)
Consumers are concerned with fat consumption from meat products and the ability to determine fat has changed with recent technological advances. The objective of this study was to determine fat percentage within marbling ...
Evaluating progestin-based protocols to control estrous cycles of beef heifers prior to timed artificial insemination
(University of Missouri--Columbia, 2018)
FTAI and STAI following administration of the melengestrol acetate (MGA[copyright]) prostaglandin F[super script 2a] protocol. Experiment 2 (Chapter 2) evaluated FTAI and STAI following administration of the 7d CO-Synch + controlled internal drug...
Extracellular vesicles : novel mediators of conceptus-maternal interactions in sheep
(University of Missouri--Columbia, 2018)
indicating a role in intercellular communication during the establishment of pregnancy; (4) uterine EV content increases more than five-fold from day 10 to 14 of the estrous cycle; (5) the endometrial epithelia produce EVs with multivesicular endosomes...
Effects of Artemisia afra and Artemisia absinthium on fertility of male mice exposed to increased ambient temperatures for 24 hours
(University of Missouri--Columbia, 2010)
Males exposed to elevated temperatures display a decrease in reproductive performance resulting in decreased profit for producers. The use of herbs to alleviate the effects of heat in tropical countries has been documented ...
Evaluation and development of early pregnancy diagnosis in dairy cattle
(University of Missouri--Columbia, 2018)
is still not understood. ISG15 expression in peripheral blood leukocytes was greater for pregnant compared with non-pregnant Holstein cows. ISG15 increased in the circulation during early pregnancy and responded to a minimal dose of 10 pg/ml when blood...
Investigation of methods and factors influencing mouse oocyte quality, in vitro fertilization and embryo development
(University of Missouri--Columbia, 2018)
Mice are one of the most commonly used rodent species as a model for biomedical research to better understand molecular, genetic, and cellular causes of human disease and disorders. The production of good quality oocytes ...
Abundance of TRIM28, SETDB1, and TP53 mRNA is dynamically regulated during porcine early embryogenesis and is abnormal in preimplantation embryos produced by in vitro fertilization in comparison to in vivo derived and nuclear transfer derived embryos
(University of Missouri--Columbia, 2013)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] In vitro embryo production is important for research in animal reproduction, embryo transfer, transgenics, and cloning. However, in vitro-derived embryos ...
Ruminal degradation of protein and carbohydrate in the domestic and wild ruminant
(University of Missouri--Columbia, 2010)
To optimize growth and health ruminant animals in a confined setting, diets need to be formulated to provide balanced levels of rumen degradable energy and nitrogen (RDN) to maximize microbial growth while also providing ...
Effect of ovulatory follicle size on bovine pregnancy associated glycoproteins in beef cattle
(University of Missouri--Columbia, 2010)
The GnRH-induced ovulation of small dominant follicles was associated with reduced pregnancy rates and late embryonic/fetal survival around the time of embryo-uterine attachment. PAGs are secreted by binucleated trophoblast ...
Regulation of early trophoblast differentiation and development
(University of Missouri--Columbia, 2010)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Placenta is a transient organ which functions in multiple ways to support the growth and survival of the developing fetus. Placenta plays a critical ...
Biology of uterine glands : impact on reproductive function
(University of Missouri--Columbia, 2018)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Pregnancy loss is the most common complication of human gestation, and roughly one-half of conceptions result in pregnancy loss, most frequently in the ...
Uterine regulation of preimplantation embryo development in fertility-classified heifers
(University of Missouri--Columbia, 2018)
, serial embryo transfer (3-4 rounds) was used to classify heifers based on pregnancy success on day 28 as high fertile (HF; 100%), subfertile (SF; 25%), or infertile (IF; 0%). Next, a series of experiments were conducted using the fertility...

Transgenerational effects of in utero heat stress on reproduction in pigs
(University of Missouri--Columbia, 2017)
Seasonal infertility caused by high ambient temperatures and humidity during the summer months can have negative effects on the reproduction of female swine. These conditions may cause heat stress leading to large economic ...
