The effects of various planes of nutrition upon the cost of maintenance, reproduction, and development of beef cows
(University of Missouri--Columbia, 1916)
The frequency with which valuable animals reproduce themselves has always been a factor of economic importance in the pure bred cattle business. Great economic changes during the last few years have made this an important ...
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)
content. Carcass characteristics, particle size and bacon quality were analyzed using GLM procedure of SAS. Growth performance and fatty acid composition were analyzed using MIXED procedure of SAS. Significance was determined at P-value < 0.05. Dietary...
Genetics in practice : applications of quantitative genetics to environment and educational pursuits
(University of Missouri--Columbia, 2018)
still segregating in HB animals. This indicates that this method may be effective for determining a limited number of high-impact genes after a short number of generations. To further resolve the architecture of the difference between these two strains...
Interaction of metsulfuron and nitrogen fertilizer in Tall Fescue forage systems
(University of Missouri--Columbia, 2022)
Tall Fescue (Schedonorus arundinaceus) is an introduced cool-season bunch grass that is a vital component of forage systems that support beef cattle production in Missouri and much of the eastern United States. This ...
Paternal effects on pre-implantation embryo development in cattle
(University of Missouri--Columbia, 2021)
Currently, sire fertility is measured using sire conception rate (SCR), which is not always indicative of embryo development. Since the majority of pregnancy loss in dairy cattle occurs during the early embryonic period, ...
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 ...
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)
embryogenesis in an effort to improve the acquisition of thermotolerance to high or low environmental temperatures post hatch (Tzschentke et al., 2001; Tzschentke and Basta, 2002; Yahav et al., 2004a,b; Piestun et al., 2008; Shinder et al., 2009). Birds may...
Exploration of fecal microbial transfer and the competitive exclusion concept in broilers as a possible alternative to antibiotic growth promoters
(University of Missouri--Columbia, 2021)
, and impact on immunocompetences from hatch to 21 days and hatch to 42 days of age, raised on used litter and wire mesh battery cages. Results in the studies here in showed that FMT treatment had a major effect (P<0.05) on growth performance for the first 7...
Characterization of the genetic landscape of feline oral squamous cell carcinoma
(University of Missouri--Columbia, 2022)
. The cancer pathology associated with feline oral squamous cell carcinoma is similar to human head and neck squamous cell carcinoma (HNSCC), which accounts for 90 percent of oral cancers in humans. FOSCC may present as a potential model to study HNSCC due...
Uterine regulation of preimplantation embryo development in fertility-classified heifers
(University of Missouri--Columbia, 2018)
Infertility and subfertility represent pervasive problems in domestic animals and humans, and embryonic mortality is a major factor influencing reproductive efficiency. In cattle, the majority of embryonic loss occurs ...
Self-selection of animal by-product by poultry through utilization of choice feeding
(University of Missouri--Columbia, 2020)
"The emergence of animal welfare provisions by humane societies has limited management practices. One of these provisions is the animal's freedom to express normal behavior. Animal by-product feeding to livestock and poultry is a common management...
Investigation of mechanisms associated with establishment and maintenance of pregnancy in beef cattle
(University of Missouri--Columbia, 2020)
, 30, and 55/58 was 100 [plus-minus] 0.02a, 40 [plus-minus] 0.02b, 32 [plus-minus] 0.02c,d, and 26 [plus-minus] 0.02D, respectively (a,b,c,dP < 0.05; D,dP = 0.0856). When the tendency for treatment as a main effect was evaluated, the Positive Control...
Biology of uterine glands : impact on reproductive function
(University of Missouri--Columbia, 2018)
-endometrial interactions and coordinate on-time implantation and stromal cell decidualization, thereby impacting embryo viability and pregnancy success. These studies also identified novel glandular factors that may be of significance to implantation and post...

Improved cloning efficiency by chemically induced metabolic reprogramming of donor cells used for porcine somatic cell nuclear transfer
(University of Missouri--Columbia, 2019)
The use of somatic cell nuclear transfer (SCNT) to create agricultural and biomedical models is extremely useful for understanding how we can improve the efficiency of production agriculture, as well as how we can better ...
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 ...
Factors affecting neonatal beef calf metabolism and vigor
(University of Missouri--Columbia, 2021)
Two studies were conducted to investigate factors affecting neonatal beef calf metabolism and vigor. In the first study, effects of late gestational nutrient restriction on colostrum yield, neonatal vigor, and blood chemistry ...
