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 ...
The relation of type and conformation to production in dairy cattle
(University of Missouri--Columbia, 1916)
Text from introduction: "The object of this investigation is to determine so far as possible how much importance should be attached to form and type in the selection of dairy cows and to what extent type may be expressed ...
The value of in-breeding in the improvement of the domestic animals
(University of Missouri--Columbia, 1917)
In this paper I shall take the stand of a neutral, and all literature and available material of value upon the subject both for and against, will be studied with a view of determining our present knowledge of in-breeding ...
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 ...
Metabolic status of late gestation beef cows and neonatal calves
(University of Missouri--Columbia, 2016)
Two studies were conducted to investigate the changes in beef cattle metabolic status over time. In the first study, the effects of grazing stockpiled tall fescue (STF) versus feeding tall fescue hay during late gestation ...
Evaluation of the retail display life of ground beef stored in modified atmosphere packaging and modern lighting conditions
(University of Missouri--Columbia, 2016)
Color is the most important factor in decision making for the consumer in the retail setting. The objective of this study was to determine the color stability of ground beef patties packaged in modified atmosphere packaging ...
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 ...
Effect of pre-ovulatory follicle size on oocyte transcript abundance in beef cows
(University of Missouri--Columbia, 2016)
Inadequate oocyte competence is a potential explanation for reduced pregnancy rates and(or) increased late embryonic mortality when small dominant follicles are induced to ovulate prematurely with gonadotropin releasing ...
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 ...
Novel alkaloid management strategies for improved beef cattle production in the fescue belt
(University of Missouri--Columbia, 2019)
Tall fescue (Schedonorus arundinaceus) is an important forage crop for agriculture in Missouri and much of the eastern United States. Tall fescue is known for hardiness and herbage accumulation, much of which is attributed ...
Generation of a reference genome to investigate population fitness and transitional cell carcinoma occurrence in the fishing cat (Prionailurus viverrinus)
(University of Missouri--Columbia, 2022)
Many species are vulnerable or on the verge of extinction as a result of increased habitat degradation and fragmentation. Conservation genetics has attempted to apply an understanding of species genetics to reduce the risk ...
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 ...
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 ...
Ablation of conceptus PTGS2 provides a new understanding of early pregnancy events in the pig
(University of Missouri--Columbia, 2019)
Pig conceptuses produce and secrete estrogens (E[2]), interleukin 1 beta 2 (IL1B2), and prostaglandins (PGs) during the period of rapid trophoblast elongation and establishment of pregnancy. Previous studies established ...
Using metabolic and biochemical characteristics of postmortem muscle to investigate the interconnectedness of beef color, flavor, and tenderness
(University of Missouri--Columbia, 2021)
Understanding relationships between beef palatability and quality components are crucial for continued production of high quality and consistent beef products. Myoglobin concentrations at 48 and 336 h resulted in moderate, ...
Glutamine metabolism and interactions with mechanistic target of rapamycin complex 1 in porcine preimplantation embryos
(University of Missouri--Columbia, 2021)
The ability to culture embryos has created opportunities for animal agriculture, including the refined selection of superior genetics, and for the medical field, allowing couples experiencing infertility to have biological ...
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 ...
Taxonomic and metagenomic approaches to diet, health, and breeds of ruminants
(University of Missouri--Columbia, 2020)
Ruminant mammals maintain a symbiotic relationship with their gut microbiome, the organisms of which break complex plant matter into metabolites that are absorbed by the host animal for its nutrition. Building on prior ...
Reduced autophagy contributes to inefficient DNA damage repair in mouse oocytes
(University of Missouri--Columbia, 2022)
The DNA damage is a major problem that, in somatic cells, leads to mutagenesis and premature aging. However, this is not the case in fully differentiated germ cells. Why DNA damage repair (DDR) machinery is not robust in ...
