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 ...
Evaluation of the efficacy of high levels of microbial phytase in broilers
(University of Missouri--Columbia, 2006)
Three experiments were conducted to evaluate the efficacy of high levels of microbial phytase in broiler diets. In experiment one (EXP 1), phytase was included in the diets at 0, 250, 500, 10,000, and 20,000 PU/kg diet. ...
Genomics of heifer pregnancy, days open, and days to conception in Red Angus heifers
(University of Missouri--Columbia, 2022)
. The DC model resulted in higher accuracy than other models. There was a high correlation between HP and DO (r = - 0.61 and 0.85 from the linear model and the liability scale model, respectively). The de-regressed estimated breeding value (EBV) genomewide...
Evaluation and development of early pregnancy diagnosis in dairy cattle
(University of Missouri--Columbia, 2018)
Early chemical pregnancy tests for use in dairy cattle are necessary to aid in reducing the costs associated with days the animal is not pregnant. Identifying non-pregnant dairy cattle sooner would allow for efficient ...
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 ...
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...
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, ...
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 ...
Relative influence of the sire and dam upon the inheritance of speed in standard trotting horses
(University of Missouri--Columbia, 1915)
Since the study of the transmission of character began, a diversity of opinion has existed and some data have been secured upon the relative influence of sire and dam in the production of offspring. From the limited data ...
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, ...
Evaluation of modified montmorillonites in poultry diets
(University of Missouri--Columbia, 2007)
The present work was conducted to determine if modification of MONTs with Cu and Zn would enhance the protection of broiler chicks against the adverse effects of AF, and to determine if the modified MONTs would be bioavailable ...
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 ...
