Evaluating The Effects Of Medium Chain Fatty Acids On Sow Reproductive Characteristics, Offspring Biological Health Markers, And Growth Performance, Analicia J. Swanson
Evaluating The Effects Of Medium Chain Fatty Acids On Sow Reproductive Characteristics, Offspring Biological Health Markers, And Growth Performance, Analicia J. Swanson
Electronic Theses and Dissertations
A sow’s diet can influence and her offspring not only in the suckling period, but well after weaning. The objective of this study was to determine how supplementing medium chain fatty acids (MCFA) in gestation and lactation impacted offspring growth performance as well as the biological markers of pig quality from the suckling period until week 6 of the nursery period. A total of 77 primparious and multiparious females and their 438 offspring were utilized in this study. Sows and gilts (218.15 kg ± 32.15 kg BW at d28 of gestation) were assigned to one of 2 dietary treatments: Control …
The Influence Of Chromium Supplementation On The Insulin Pathway, Carcass Traits, And Meat Quality Of Feedlot Steers, Heather Rode
The Influence Of Chromium Supplementation On The Insulin Pathway, Carcass Traits, And Meat Quality Of Feedlot Steers, Heather Rode
Electronic Theses and Dissertations
Chromium supplementation (Cr) can increase efficiency of growth in livestock by amplifying insulin signaling. Previous research showed Cr increases nutrient utilization and changes in muscle growth and fat deposition. Therefore, the objective of this research was to determine how Cr affects carcass traits, meat quality, and the insulin pathway in feedlot steers. Calf-fed steers were allotted to 0 ppb (CON) or 400 ppb Cr propionate (Cr400) for 210d in experiment 1. Two longissimus muscle (LM) biopsies were collected to examine protein abundance and gene expression after adaptation to a terminal implant and after adaption to ractopamine hydrochloride (RAC). A follow …
The Effect Of Copper And Zinc Source On Pre-Weaning Performance Of Cows, Health And Performance Of Suckling Calves, And Post-Weaning Feedlot Performance, Carcass Composition, And Meat Quality Of Calves, Jesse Fulton
Electronic Theses and Dissertations
During gestation an elevated level of nutrient intake is required by the cow in order to meet the requirements of the maturing fetus and if these requirements are not met, changes in fetal development can occur. However, little is understood about the effects of gestational manipulation of specific nutrients, such as minerals, on progeny growth, performance and carcass traits. Previous research supports the hypothesis that minerals provided in an organic form should be more soluble and readily available to the body for absorption. Therefore the objectives of this study were to determine if source of gestational and post-natal Cu and …
Temperature Computer Measurements, Production And Carcass Traits Of Individually Fed Weight Constant Steers, Lowell M. Anderson
Temperature Computer Measurements, Production And Carcass Traits Of Individually Fed Weight Constant Steers, Lowell M. Anderson
Electronic Theses and Dissertations
During 1968, 29 Hereford steers were individually fed and marketed at one of seven constant weight classes from approximately 386 to 522 kg at intervals of 22.7 kg. During 1970, 21 Angus and Hereford crossbred steers were individually fed and marketed at one of four constant weight classes from approximately 386 to 522 kg at intervals of approximately 45.0 kg. The amounts of edible portion, trimmed fat, removed bone and the summation of the kidney, pelvic, and cod fat were determined on the steers of both years. In 1970 two experiments examined the usefulness of an analog computer for calculation …
