Developmental exposure to bisphenol a (BPA) and ethinyl estradiol (EE) and effects on F1 parental care and F2 pup parameters in California mice (Peromyscus californicus)
(University of Missouri--Columbia, 2017)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Environmental exposure during the perinatal period can promote health and disease in offspring, otherwise coined developmental origins of health and ...
Effects of low crude protein diets with amino acid supplementation on broiler performance in the starter period
(University of Missouri--Columbia, 2009)
A series of experiments were conducted to examine the effects of feeding low crude protein (CP) corn and soybean meal diets with crystalline amino acid supplementation to broilers from 0-3 weeks of age. It was hypothesized ...
Evaluating pig performance, carcass merit and processed pork quality when chestnuts and acorns are fed to Duroc-influenced pig genetics during late finishing
(University of Missouri--Columbia, 2019)
The objective of this study was to determine effects of feeding chestnuts and acorns on growth performance, carcass quality and further processed products of Duroc/Duroc crossbred finishing barrows. Barrows (n = 30) were ...
Effects of late gestational copper, zinc, and manganese source and inclusion in beef cattle
(University of Missouri--Columbia, 2019)
A study was conducted to determine the effects of source and inclusion of Cu, Zn, and Mn during late gestation on cow and calf mineral status, fetal growth, and offspring immune function and pre-weaning performance. Cows ...
Zinc ion fluxes on the pathway to mammalian sperm fertilization competency
(University of Missouri--Columbia, 2019)
For decades, the role of the divalent ion calcium was the focus of understanding mechanisms leading to sperm fertilization competency and management of semen storage. Little focus has been placed on other divalent ions, ...
Estimates of correlation between estrus behavior and estradiol concentrations during estrus
(University of Missouri--Columbia, 2020)
Estrus traits have economic value in dairy production systems and can potentially be incorporated into genomic selection. Three studies were performed to further understand selection responses. Study one and two explored ...
Conceptus interferon gamma is essential for pregnancy maintenance in the pig
(University of Missouri--Columbia, 2021)
Establishment and maintenance of pregnancy in the pig is a complex process that relies on adequate communication between the conceptus and maternal uterine endometrium. During the peri-implantation period, the conceptuses ...
Factors affecting neonatal and peripartum maternal metabolism and behavior in beef cattle and horses
(University of Missouri--Columbia, 2018)
Three studies were conducted to investigate perinatal changes in metabolism and behavior of beef cattle and horses. In the first study, effects of parity on perinatal nutrient availability assessed through calf size and ...
New perspective on the role of conceptus estrogens in conceptus development, maternal recognition, and the establishment of pregnancy in pigs.
(University of Missouri--Columbia, 2018)
The proposed signal for maternal recognition of pregnancy in pigs is estrogen, produced by the elongating conceptus. To understand the role of estrogen in porcine conceptus elongation and pregnancy establishment, a loss ...
Regulation of fetal brain development in short versus long lived mice
(University of Missouri--Columbia, 2022)
How fetal brain development is regulated in mice with reduced life span is a primary objective of this research. Three studies were performed to investigate the fetal brain development in short and lived mice strains. The ...
Effects of essential oils on the performance, health, and feeding behavior of growing cattle
(University of Missouri--Columbia, 2021)
Concerns and changes in policy related to use of antimicrobials in livestock has led to increased interest in using alternative feed additives such as essential oils (EO). Essential oils are plant secondary metabolites ...
The role of the mammary gland during heat stress
(University of Missouri--Columbia, 2019)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Disruptive effects of climate change, such as increasing environmental temperature, have direct impacts on economic viability and efficiency of food ...
Uterine regulation of preimplantation embryo development in fertility-classified heifers
(University of Missouri--Columbia, 2018)
Infertility and subfertility represent pervasive problems in domestic animals and humans, and embryonic mortality is a major factor influencing reproductive efficiency. In cattle, the majority of embryonic loss occurs ...
Extracellular vesicles : novel mediators of conceptus-maternal interactions in sheep
(University of Missouri--Columbia, 2018)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Infertility and pregnancy loss are common problems affecting reproductive efficiency, health and development in livestock. Pregnancy loss occurs most ...
Investigating the role of a lncRNA (4833427F10Rik) in mouse placental development and function
(University of Missouri--Columbia, 2022)
Long non-coding RNAs (lncRNAs) have traditionally been viewed as transcriptional noise. However, experimental evidence of their cell-type-specific expression, presence of functional genetic elements, along with their role ...
Factors affecting neonatal beef calf metabolism and vigor
(University of Missouri--Columbia, 2021)
Two studies were conducted to investigate factors affecting neonatal beef calf metabolism and vigor. In the first study, effects of late gestational nutrient restriction on colostrum yield, neonatal vigor, and blood chemistry ...
Genetics in practice : applications of quantitative genetics to environment and educational pursuits
(University of Missouri--Columbia, 2018)
"The ability to elucidate quantitative trait architecture and introduce potentially beneficial traits makes introgression a useful tool. Unfortunately, due to the nature of inheritance there are certainly limitations to ...
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 ...
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
