Genetics in practice : applications of quantitative genetics to environment and educational pursuits
(University of Missouri--Columbia, 2018)
in consumption was due to a minimum of about 10-12 genes. Such a high number of genes with little information on architecture makes reliable phenotypic selection difficult. Ultimately, we determined the phenotype was lost in LB animals but about six genes were...
Self-selection of animal by-product by poultry through utilization of choice feeding
(University of Missouri--Columbia, 2020)
practice and it is stigmatized in the public eye and some animal welfare activists. Certification processes by organizations like the Humane Farm Animal Care association are trying to remove the use of animal by-products from animal feed and move to more...
Determination of fat percentage using three different methods within marbling scores on beef longissimus muscle
(University of Missouri--Columbia, 2010)
Consumers are concerned with fat consumption from meat products and the ability to determine fat has changed with recent technological advances. The objective of this study was to determine fat percentage within marbling scores and compare three fat...
Growth, performance and quality attributes of steers supplemented with high oleic soybean oil
(University of Missouri--Columbia, 2019)
Growing concerns with saturated fatty acids on human health has led to research being done to reduce saturated fatty acid levels in animal tissues. The objective of this study was to evaluate the effect of high oleic soybean ...
Genotype by environment interaction estimated by using reaction norms in cattle
(University of Missouri--Columbia, 2008)
on environment means (SAS PROC GLM and ASREML). Regression coefficients differed among bulls for all traits (P [less than] 0.0001). Heritability estimates with pedigree information ranged from 0.293 to 0.401 for birth weight; 0.141 to 0.289 for weaning weight...
Comparison of controlled internal drug release (CIDR)-based protocols to synchronize estrus and facilitate artificial insemination (AI) in postpartum beef cows
(University of Missouri--Columbia, 2008)
Artificial insemination (AI) and estrous synchronization are reproductive technologies that enable beef producers to efficiently improve herd genetics. The recent development of protocols designed to synchronize estrus and ovulation enable producers...
Transcriptional profiling by deep sequencing indentifies [sic] differences in mRNA transcript abundance in in vivo derived vs. in vitro cultured porcine blastocyst stage embryos
(University of Missouri--Columbia, 2010)
In vitro embryo culture systems promote development at rates lower than in vivo. The goal of this project was to discover transcripts that may be responsible for a decrease of embryo competency in blastocyst stage embryos ...
Phenotypic and genetic effects of disposition on beef tenderness and quality attributes
(University of Missouri--Columbia, 2011)
and are profitable to producers. The American Simmental Association (ASA) provided records which included pedigree information, multiple WBSF core values, reported as average peak shear force (APSF), and a maximum of two EV measurements taken 42 days apart. Bayesian...
Identification and quantification of differentally represented transcripts in preimplantation bovine embryos
(University of Missouri--Columbia, 2007)
implications of embryo manipulation, but may also lead to the improvement of current assisted reproductive technologies....
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)
reductions with an assumed correlate to lower fitness. Better management strategies could be implemented if these principles can be used to determine the evolutionary context of endangered or vulnerable species. With sequencing technologies rapidly advancing...
Improving viability of immunodeficient RAG2-/- pigs by non-specific porcine antibody administration
(University of Missouri--Columbia, 2020)
was reported in our immunocompetent wildtype pigs as remaining present in vivo over 0.05 [mu]g/mL for 10 days yielding a half-life of approximately 3.5 days, even though IgG has been described to have a half-life of 21 days....
Effect of high peroxide value fats on performance of broilers in normal and immune challenged states
(University of Missouri--Columbia, 2009)
A series of trials were conducted in order to determine the effects of high peroxide value fats on performance of broilers in normal and immune challenged states from 0-49 days of age. In the first experiment, birds were ...
Comparative transcriptional profiling of the uterus according to stage of the estrous cycle and pregnancy status in gilts
(University of Missouri--Columbia, 2007)
In most mammals, female reproductive tracts undergo extensive tissue remodeling throughout the estrous cycle and during pregnancy that arise in response to an array of endocrine, paracrine, and autocrine signals. These ...
Altering the timing of fixed-time artificial insemination and the interval from progestin withdrawal to prostaglandin F2a administration in estrus synchronization protocols for beef heifers
(University of Missouri--Columbia, 2022)
(CIDR; 1.38 g progesterone) on Day -33 and removal on Day -19, and administration of prostaglandin F2a (PG; 500 [mu]g cloprostenol sodium) on Day -3. Within location, heifers were blocked based on reproductive tract score and body weight and were...
The relationship between mitochondria and residual feed intake in feedlot cattle
(University of Missouri--Columbia, 2006)
Residual feed intake (RFI) is a measure of feed efficiency that is not related to an animal's growth rate or body size. Little is known about the factors that affect RFI because, until recently, the measurement of RFI in ...
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 ...
Applications of ancestry estimation in cattle population genetics
(University of Missouri--Columbia, 2019)
Accounting for ancestry and cryptic population structure is important in population genetic data analysis. The estimation of ancestry can help elucidate the effects of admixture or stratification on allele and genotype ...
The effects of the selective estrogen receptor modulators MPP and raloxifene in normal and cancerous human and murine uterine tissue
(University of Missouri--Columbia, 2007)
The goal of this research was to determine the in vitro and in vivo effects of the Selective Estrogen Receptor Modulators (SERMs), methyl-piperidino-pyrazole (MPP), raloxifene, ICI 182,780 and 17[beta]-estradiol on endometrial ...
Selection for placental efficiency in swine
(University of Missouri--Columbia, 2004)
With the overall goal of increasing profitability by increasing litter size, two lines of pigs were divergently selected for four generations on an index of reproductive traits (n = 193 litters). The selection index (SI) ...
Determination of allelic expression of H19 in pre- and peri-implantation mouse embryos
(University of Missouri--Columbia, 2013)
H19 is a maternally-expressed imprinted non-coding RNA with tumor suppressor activity. H19 is located in an imprinted cluster which contains the paternally-expressed fetal growth factor Igf2. Monoallelic expression of H19 ...
