Effects Of Bovine Maternal Nutrient Restriction On Offspring Microrna And Mrna Expression And Muscle Fiber Type, Nikole E. Ineck

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

For producers in more temperate areas, such as the Intermountain West, poor nutrition during the second trimester of gestation is common due to seasonal changes in forage and nutrient availability. The majority of muscle fibers are formed and adipogenesis is initiated in the second trimester, making it a critical time for skeletal muscle and adipose development in beef cattle. However, the extent to which these changes persist in the offspring postnatally is unknown. In this study, maternal nutrition was restricted during the second trimester in order to analyze the effects of maternal nutrient restriction on offspring skeletal muscle growth. Offspring …

Effects Of Gestational Dietary Intake On Calf Growth And Early Feedlot Performance Of Offspring, Jose M. Gardner

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Fetal programming is a relatively new and quickly growing field of research in the livestock industry. The concept of fetal programming is simply defined as the effects a change in maternal nutritional intake has on offspring, whether it be a genetic or physical change. The intention of this study was to specifically look at the effects of nutrient restriction of cows during the second trimester of gestation on the growth and performance of the resulting calves.

In this study, thirty-two cows of predominantly angus influence from the Utah state university herd were chosen, naturally bred to a pure bred angus …
