Biological Abnormalities in the Ruminant Small Intestine and Its Relationship to Carbohydrate Assimilation
(North Dakota State University, 2019)
Several biological abnormalities exist between the ruminant and nonruminant small intestine and influences carbohydrate assimilation. Two experiments were conducted to identify potential mechanisms to improve carbohydrate ...
Influence of Maternal Nutrient Intake on Placental Vascular Function in Pregnant Beef Cows
(North Dakota State University, 2014)
Two experiments investigating impacts of maternal nutrition in beef cows were conducted; 1) to test the impact of duration of global nutrient restriction and subsequent realimentation throughout gestation on placentome ...
The Effects of Sex, Breed, and Slaughter Weight on Growth, Carcass, and Sensory Characteristics of Lamb
(North Dakota State University, 2018)
American lambs are often over-finished and lack consistent quality. It has been suggested that the use of intact ram lambs can decrease USDA YG and improve growth efficiency. However, ram lamb carcasses are underutilized ...
Can Hematocrit Levels at Estrus in Dairy Cows and Sheep Be an Indicator for Pregnancy Success?
(North Dakota State University, 2019)
Despite the major reproductive advances in the livestock industry, prenatal embryonic loss is still one of the major issues that causes substantial economic loss. While there are many tests available to determine pregnancy ...
Effects of Linseed Meal on Growth and Reproductive Performance in Ruminants
(North Dakota State University, 2011)
Linseed meal (LSM) was fed to ovariectomized ewes exposed to estradiol 17-ß (E2)
implants over time, and LSM was supplemented to beef cows during late gestation and
early lactation to evaluate the estrogenic potential ...
Body Weight and Adiposity Changes of Obese Gilts Provided Ad Libitum Ground Beef Versus High Carbohydrate Diets
(North Dakota State University, 2014)
This study investigated the impact of providing a red meat (GB; cooked ground beef; 63% lean) or high-carbohydrate diet (CON) on growth performance and body composition of obese gilts as a biomedical model for humans. ...
The Use of Behavioral Measures to Quantify Welfare in Dairy Cows and Lambs
(North Dakota State University, 2014)
The primary objective of the experiments described in this thesis was to use quantitative behavioral measures of livestock to evaluate animal welfare. In one study, the effects of a therapeutic drug in lame dairy cows were ...
Evaluation of a Novel Means to Euthanize Piglets
(North Dakota State University, 2012)
Research was conducted to evaluate a novel means to euthanize piglets utilizing electromagnetic energy. Experiment 1 assessed if electromagnetic energy could result in a euthanized piglet and Experiment 2 evaluated states ...
Factors Influencing the Passive, Innate, and Adaptive Immune System and Their Effects in Beef Cattle
(North Dakota State University, 2015)
To investigate the factors influencing the passive, innate, and adaptive immune system
and their effects in beef cattle, three experiments (exp.) were completed. Results from Exp. 1
indicate that there is some influence ...
Effects of Nutrient Restriction, Realimentation, and Parity on Umbilical Hemodynamics in the Pregnant Ewe
(North Dakota State University, 2016)
Sheep are normally managed within grazing systems; forage availability and quality are dependent upon seasonal conditions such as drought and humidity. It is therefore important for producers to know when during gestation ...
