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 individually housed in pens...
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 work describing the taxonomic...
Genetic and nutritional effects on reproduction in lactating dairy cows
(University of Missouri--Columbia, 2020)
background but are influenced by maternal nutrition. Study four investigated the association between milk PAG S-N in early gestation with variables related to the dam, sire and gestating fetus. Dam genetic merit for milk production did not have a large effect...
Net energy content of soybean meal and glycerol for growing and finishing pigs
(University of Missouri--Columbia, 2009)
Net energy systems are widely accepted and utilized throughout Europe. The main net energy systems used are the French INRA, the Dutch CVB and the Danish PPE. These energy systems are not widely accepted in the U.S. due ...
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 disease (DOHaD). Endocrine...
Effects of heat stress on leukocyte function and gene expression in lactating dairy cows
(University of Missouri--Columbia, 2018)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] The effects of heat stress in animal agriculture are expected to become more serious as global temperatures continue to increase. Negative effects on production, reproduction...
Cotton seed and cotton-seed products as feeds for live stock
(University of Missouri--Columbia, 1916)
The purpose of this work was to get together the results of the different experiments with cotton seed and cotton seed products in order that comparisons might be made of the feeding values of the different products with ...
Effects of the bovine slick mutation on heat stress responses and hair growth in mice
(University of Missouri--Columbia, 2020)
The bovine slick mutations result from more than one allele variant causing a slick hair phenotype and improved thermotolerance to elevated ambient temperatures in cattle. These mutations result in the truncation of the ...
Tissue inhibitor of metalloproteinase-1 contributes to reduced fecundity in a rat model of endometriosis
(University of Missouri--Columbia, 2008)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Endometriosis affects millions of women worldwide; its symptoms are pain and reduced fecundity. An established rat model was used which endometriosis is surgically induced (Endo...
Involvement of mitochondrial transcription factor A (TFAM) in porcine gametogenesis and preimplantation embryo development
(University of Missouri--Columbia, 2007)
Mitochondrial Transcription Factor A (TFAM) is responsible for maintenance and transcriptional control of mitochondrial DNA (mtDNA). TFAM knockout is embryolethal. We have studied the expression and distribution of TFAM ...
Alleviation of heat stress with Tasco in dairy cows
(University of Missouri--Columbia, 2010)
The present study determined the impact of Tasco, Ascophyllum nodosum, on heat stress in dairy cows. Thirty-two Holstein cows were utilized in a randomized complete block design, during 63 days in summer 2008. Feed intake, ...
Comparison of CIDR-based protocols to synchronize estrus in beef heifers
(University of Missouri--Columbia, 2007)
Estrus synchronization and artificial insemination (AI) are reproductive management techniques that allow beef producers to enhance the reproductive efficiency and genetic composition of their cow herd. However, U.S. beef ...
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)
result, most Cav-1- null mice die within a year. Gene expression in bulk brain tissue as well as single cells were analyzed in the Cav-1-null fetal brain compared to the wildtype (WT). The results of this study showed that lack of Cav-1 leads to extensive...
