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 ...

Two studies investigated methods of decreasing feed costs of cow-calf operations. In the first study, two experiments were conducted to determine the difference in grazed forage intake of beef cows of known residual feed ...

Enzymatic 11 [beta] HSD1 amplification of glucocorticoid concentrations in adipose tissue has been associated with obesity, diabetes, hypertension, dyslipidemia, and cardiovascular disease in humans and mice. Unfortunately, ...

[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Experiment 1 evaluated two long-term progestin-based and controlled internal drug release estrus synchronization protocols to determine their potential ...

[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Fescue toxicosis is results from intake of tall fescue grass containing a fungal endophyte. It affects most of herbivore species, including rodents. ...

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 ...

The Pregnancy Associated Glycoproteins (PAGs) represent a multigene family of trophoblast expressed proteins, found exclusively in the placenta of even-toed mammals such as ruminants (cattle, sheep), pig, etc. In ruminants, ...

The objective of this study was to evaluate GxE by comparing reaction norms among U.S. Angus bulls. Dependent variables were adjusted weights at birth, 205 d weaning, and 365 d yearling. Environments were defined as progeny ...

This thesis examines ruminant digestion, ecology, and evolution, particularly where they can improve livestock production systems. We performed an experiment that estimated ruminal in situ degradation parameter values of ...

Two Bos taurus breeds with known differences in heat tolerance were tested under controlled conditions to evaluate heat tolerance. Romosinuano (RO) is a tropically adapted breed. Nine Angus (304 [plus or minus] 7 Kg BW; ...

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 ...

Residual feed intake (RFI) is the difference between measured feed intake and predicted feed intake of an animal. Intake prediction is computed from a regression of intake on gain and metabolic body weight. Residual feed ...

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 ...

[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Selection for high milk production has created a physiologically different dairy cow with lower fertility. The growth hormone (GH)/insulin-like growth ...

[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 ...

[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] The need to balance no-roughage, corn-based feedlot diets for rumen degradable protein inclusion is essential in the feedlot setting. Five crossbred ...

Fescue toxicosis affects domestic animals grazing fescue pasture infected with the endophytic fungus, Neotyphodium coenophialum. Signs of fescue toxicosis include increased body temperature and respiration rate and decreased ...

It was the objective of these experiments to more fully characterize the biochemical and developmental responses of in vitro-produced preimplantation stage porcine embryos to elevated temperatures. In vitro fertilized (IVF) ...

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 ...

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 ...
