Impacts of Flax on Female and Male Reproductive Traits When Supplemented Prior to Breeding in Sheep
(North Dakota State University, 2018)
Two experiments determined the effects of flaxseed supplementation on reproductive parameters in sheep. In experiment one, 240 multiparous Rambouillet ewes were assigned to one of two treatments: basal ration alone or basal ...
Effects of Maternal Nutrition, Intrauterine Growth Restriction (IUGR), and Estrogen (E2) Supplementation on Placental and Fetal Intestinal Growth and Development in Sheep
(North Dakota State University, 2012)
The placenta and fetal intestines are two key nutrient transport organs that sustain and nurture growing fetus. Insufficient placental development and consequently inadequate fetal nutrient supply can lead to IUGR resulting ...
Arginine Supplementation Strategies during Gestation: Impacts on Dams and Offspring
(North Dakota State University, 2015)
We hypothesize rumen-protected arginine supplementation during gestation will mitigate deleterious offspring effects caused by undernutrition. Experiment 1: non-pregnant ewes were supplemented with rumen-protected arginine ...
Management Considerations for Successful Technology Implementation in Beef Production Systems
(North Dakota State University, 2015)
Two experiments were conducted to evaluate management strategies that foster successful implementation of technology in beef production systems. In experiment 1, cow reproductive performance, BW, and serum concentrations ...
The Use of Subjective and Objective Methods of Behavioral Evaluation in Swine and Dairy Cattle
(North Dakota State University, 2017)
The objectives of the studies described in this thesis were to quantify livestock behavior and improve animal wellbeing. Subjective and objective evaluation methods can be used as an estimation parameter of animal welfare. ...
The Relationship between Pre-Harvest Stress and Carcass Characteristics and the Ability to Qualify for Kosher on Beef Steers and Heifers
(North Dakota State University, 2013)
The objective of this study was to determine if there is a difference in pre-harvest stress and carcass characteristics between kosher and not-qualified-as kosher cattle. Cattle that had a shorter time from gate to ...
The Role of Supplemental Beef vs. Sugar during Pregnancy on Fetal and Offspring Developmental Programming in Swine
(North Dakota State University, 2019)
Sugar intake is linked to developmental programming of obesity and diabetes. We hypothesized that supplementing ground beef in place of sugar during pregnancy would reduce fetal and offspring developmental programming. ...
The Effects of Feeding Seaweed Extract in the Diet of Swine on Gut Health, Performance, Carcass Characteristics, and Pork Quality
(North Dakota State University, 2017)
Consumers are concerned about antibiotic and ractopamine usage; therefore, alternatives need to be found. Objectives of this study were to investigate the effects of using seaweed as an alternative feed supplement and ...
Effects of Grain Type and Oil Concentration of Corn Dried Distillers Grains Plus Solubles of Digestion, Finishing Performance, and Carcass Quality
(North Dakota State University, 2016)
Changes in ethanol processing have resulted in a reduction of oil in the final coproduct, DDGS, available as a feedstuff. Lowering the oil concentration can decrease the total energy in the diet and, therefore, could affect ...
Effects of Alternate Day Feeding of Dried Distiller’s Grains Plus Solubles and Grass Hay on Metabolism and Performance in Cattle
(North Dakota State University, 2012)
Two studies were conducted to determine the effects of supplementing dried distiller's grains plus solubles (DDGS) on alternate days to forage-fed cattle. We hypothesized that feeding either DDGS at a low percent of body ...
