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 ... -
The effect of reduced nocturnal temperatures on the performance of broiler chicks and hen turkey poults from 0 to 21 days of age
(University of Missouri--Columbia, 2018)The world population has increased over the past century and with this increase in the world population comes an increase in demand of animal protein for consumption. The United States produced 8.78 billion broilers and ... -
Biology of uterine glands : impact on reproductive function
(University of Missouri--Columbia, 2018)Pregnancy loss is the most common complication of human gestation, and roughly one-half of conceptions result in pregnancy loss, most frequently in the first two weeks of gestation. In humans, uterine gland dysfunction is ... -
Extracellular vesicles : novel mediators of conceptus-maternal interactions in sheep
(University of Missouri--Columbia, 2018)Infertility and pregnancy loss are common problems affecting reproductive efficiency, health and development in livestock. Pregnancy loss occurs most commonly during the first weeks of gestation and may arise due to ... -
Development and analysis of a foxa2 conditional overexpression mouse model
(University of Missouri--Columbia, 2018)The uterus is essential for mammalian reproduction as it provides environment for conceptus implantation and subsequent development. Endometrial glands synthesize and secrete or transport substances critical for conceptus ... -
Galaxy evolution as seen by Herschel
(University of Missouri--Columbia, 2018)$$ The unprecedented Herschel data have revolutionized our view of the IR universe, providing new insights to galaxy formation and evolution. However, the Herschel data are still far away from being fully explored, mainly ... -
The effect of various levels of yellow grease in pre-starter rations on performance of turkey poults
(University of Missouri--Columbia, 2016)Nutritional intervention in the early growing poult can be a valuable strategy to decrease the stress experienced during the transition from endogenous yolk sac lipid reserves to an exogenous feed source. The objective of ... -
A phenomenological study of queer and trans students of color
(University of Missouri--Columbia, 2017)Queer and trans student experiences are understudied in higher education, quantitatively and qualitatively alike. Despite the number of studies growing on queer and trans students, numerous studies (e.g. Abes,2011; Bonner, ... -
Gold nanoclusters and fluorescence-based sensing
(2017)The main topic of this dissertation focuses on development of analytical methods, mainly modification and application of metal nanoclusters in fluorescence-based sensing. Based on bovine serum albumin passivated gold ... -
Genetic linkage of multiple modifications in the pig
(University of Missouri--Columbia, 2015)Genetic engineering facilitates heritable modification of target genomes. Modifications can be site-specific or random. Though inefficient, homologous recombination allows for precise genome modification. Random integration ... -
Molecular characterization of a congenital overgrowth syndrome induced by assisted reproduction
(University of Missouri--Columbia, 2017)Beckwith-Wiedemann syndrome (BWS) is a congenital overgrowth condition with increased likelihood to develop childhood tumors. Children conceived with the use of assisted reproductive technologies (ART) have an increased ... -
Ruminal degradation of protein and carbohydrate using a batch culture system, and response to roughage removal, rumen modifier inclusion and postruminal amino acid supply in feedlot cattle.
(University of Missouri--Columbia, 2017)Three main studies were conducted to characterize protein and carbohydrate ruminal degradation using a batch culture system, demonstrate and responses to roughage removal, rumen modifiers inclusion and postruminal amino ... -
The impact of fescue toxicosis & T-Snip score on post-weaning beef cattle performance
(University of Missouri--Columbia, 2017)It is well known that fescue toxicosis has a negative impact on cattle productivity. These studies were conducted to evaluate the effects of fescue toxicosis on post-weaning beef steers, as well as the impact of T-Snip ... -
Potential diagnostic methods and nutritional changes to combat bovine respiratory disease in receiving cattle
(University of Missouri--Columbia, 2017)Bovine respiratory disease (BRD) accounts for up to 70 percent of health disruptions and $500 million in associated medical costs and production losses, thus receiving considerable attention from cattle health personnel ... -
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 ... -
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)Environmental exposure during the perinatal period can promote health and disease in offspring, otherwise coined developmental origins of health and disease (DOHaD). Endocrine disruptors, such as bisphenol A (BPA, widely ... -
Phosphorus digestibility of corn and soybean meal (SBM) in broilers: in search of a consistent and reliable model to quantify individual ingredient contribution
(University of Missouri--Columbia, 2017)Two experiments were conducted to determine true digestibility of Phosphorus (P) in feed ingredients commonly in commercial broiler diets. A second objective was to determine if the true digestible P values of corn and ... -
Novel feed additives to improve lipid profiles in pigs
(University of Missouri--Columbia, 2016)Opportunities to export high quality pork products to trade partners like Japan are economically favorable outlets for US pork producers. Domestic consumers also rely heavily on fresh pork appearance, especially color and ... -
