Modification of porcine rhodopsin by CRISPR/Cas9 : towards a model for Retinitis Pigmentosa
(University of Missouri--Columbia, 2016)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Retinitis Pigmentosa (RP) is a disease characterized by progressive vision loss, which affects approximately 1 in 4,000 people in the United States. ...
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, ...
Contemporary light sources and their impact on the discoloration and oxidation of fresh beef products
(University of Missouri--Columbia, 2017)
Discolored fresh meat products in a retail setting are often perceived negatively by consumers when making purchasing decisions. Prolonging fresh meat color is critical for the retail industry in regard to sales and consumer ...
Evaluation of heat-processed sorghum, high-oleic and low-trypsin inhibitor soybean cultivars as alternatives for corn and conventional soybeans for broilers
(University of Missouri--Columbia, 2017)
Four 21-d experiments were conducted to compare soybean meal (SBM) from high oleic to parent soybean cultivars on growth performance, energy and ileal AA (IAA). Soybean meal was prepared by laboratory-scale mechanical ...
Biological role of conceptus derived factors during early pregnancy in ruminants
(University of Missouri--Columbia, 2016)
In cycling domestic animals, pregnancy loss during early gestation is a major cause of infertility. The majority of pregnancy loss during this time is due to errors in mitotic division early in development, or occurs later ...
Effect of preovulatory follicle size on cumulus cell and follicular wall transcript abundance in beef cows
(University of Missouri--Columbia, 2017)
Gonadotropin releasing hormone (GnRH)-induced ovulation of small dominant follicles decreased pregnancy rates and increased late embryonic/fetal mortality in postpartum beef cows, which could be caused by inadequate oocyte ...
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 ...
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 ...
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 ...
Autophagy and ubiquitin-proteasome system during post-fertilization sperm mitophagy
(University of Missouri--Columbia, 2016)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Maternal inheritance of mitochondria and mitochondrial DNA (mtDNA) is a universal principle in developmental biology. Mammalian sperm-borne mitochondria ...
Dietary fat source alters pork fat quality
(University of Missouri--Columbia, 2010)
During the last decade, several changes have taken place in the swine industry. There has been an increase in the use of distillers dried grains with solubles (DDGS) which, depending on the level included in the diet, may ...
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 ...
Multivariate genome-wide association studies and genomic predictions in multiple breeds and crossbred animals
(University of Missouri--Columbia, 2016)
The aim of the first research project is to design a commercialized genomic test that strongly predicts meat tenderness and other carcass traits in multiple breeds and crossbred cattle. We have identified single nucleotide ...
Diet shifts provoke complex and variable changes in the metabolic networks of the ruminal microbiome
(University of Missouri--Columbia, 2016)
Grazing mammals rely on their ruminal microbial symbionts to convert plant structural biomass into metabolites they can assimilate. To explore how this complex metabolic system adapts to the host animal's diet, we inferred ...
Postpartum hormones and metabolites affecting fertility in Holstein and Jersey dairy cows
(University of Missouri--Columbia, 2016)
Dairy cows have experienced major changes in productivity during the past 70 years. A selective pressure was applied to increase milk yield, but fertility declined. During early lactation, dairy cows are exposed to ...
Nutritional intervention in the early growing broiler chick
(University of Missouri--Columbia, 2016)
As the broiler chicken continues to grow faster and larger, the time to slaughter continually decreases. Broilers are commonly slaughtered at 5-8 weeks of age and so the post-hatch period has become a larger and more ...
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 ...
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 ...
