Simulated Winter Incubation Of Soil With Swine Manure Differentially Affects Multiple Antimicrobial Resistance Elements, Daniel N. Miller, Madison E. Jurgens, Lisa M. Durso, Amy Schmidt
Simulated Winter Incubation Of Soil With Swine Manure Differentially Affects Multiple Antimicrobial Resistance Elements, Daniel N. Miller, Madison E. Jurgens, Lisa M. Durso, Amy Schmidt
United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications
Gastrointestinal bacteria that harbor antibiotic resistance genes (ARG) become enriched with antibiotic use. Livestock manure application to cropland for soil fertility presents a concern that ARG and bacteria may proliferate and be transported in the environment. In the United States, manure applications typically occur during autumn with slow mineralization until spring planting season. A laboratory soil incubation study was conducted mimicking autumn swine manure application to soils with concentrations of selected ARG monitored during simulated 120-day winter incubation with multiple freeze-thaw events. Additionally, the effects of two soil moistures [10 and 30% water holding capacity (WHC)] and two manure treatments …
Effect Of Feed Additives And Toxic Elements On Swine Growth Performance, Nutrient Digestibility, Immune Function And Reproductive Performance, Richard A. Mudarra Hernández
Effect Of Feed Additives And Toxic Elements On Swine Growth Performance, Nutrient Digestibility, Immune Function And Reproductive Performance, Richard A. Mudarra Hernández
Graduate Theses and Dissertations
To evaluate the effects of peptide in combination of zinc oxide (Zno) or acidifiers (Exp 1), and gossypol (G) from cottonseed meal (CSM) ( Exp 2&3) on growth performance, complete blood cell counts (Exp 1, 2&3), nutrient digestibility (Exp 1), plasma gossypol (Exp 2&3) and semen quality (Exp 3), weaned pigs (Exp 1), growing gilts (Exp 2) and growing boars (Exp 3) were randomly allotted to dietary treatments. Treatments for Exp 1 during phase 1&2 were: (1) Positive Control (PC), formulated to meet NRC (2012) nutrient requirements; (2) Negative control (NC), fish meal was reduced to achieve -0.13% SID lysine; …

The objective of this study was to examine structure and body conformation traits of 494 gilts/sows as a prediction of reproductive longevity in sows. This study focused on specific traits including body length, body depth, front and rear pastern angles, knee angle, and hock angle. The primary method of data collection was based on videos. Still images were pulled from the videos when the sow was standing in a natural stance. The images were analyzed and interpreted objectively with Image J which gives the availability to measure distance and angles given known references in the images. The structural data was …

Mortality within livestock production has a substantial impact on economic sustainability of enterprises. The livestock industry has a unique opportunity to maximize animal welfare and production efficiency by minimizing morbidity and mortality. To do so, investigators must appropriately balance the utilization of limited resources with the quantity necessary for robust research. The objective of the study was to illustrate the use of readily implementable statistical models to determine sample size necessary to detect statistically significant differences between groups with varying levels of mortality. To this end, a series of examples were created where the unit to which a treatment is …

Kansas Agricultural Experiment Station Research Reports
It is with great pleasure that we present the 2020 Swine Industry Day Report of Progress. This report contains updates and summaries of applied and basic research conducted at Kansas State University during the past year. We hope that the information will be of benefit as we attempt to meet the needs of the Kansas swine industry.
The Effect Of Triptorelin On Ovulation Rate And Conception Rate In Gilts And The Endocrine Profile In Non-Pregnant And Early Pregnant Gilts, Joseph Wollbrink
The Effect Of Triptorelin On Ovulation Rate And Conception Rate In Gilts And The Endocrine Profile In Non-Pregnant And Early Pregnant Gilts, Joseph Wollbrink
Electronic Theses and Dissertations
Triptorelin is a gonadotropin releasing hormone agonist that has been shown to be effective in weaned sow single fixed time artificial insemination protocols. Administration of triptorelin 96 h after weaning has been shown to be effective in synchronizing sows to be inseminated one time 24 h later without reducing pregnancy rate or the number of pigs born. In the current experiment, 23 crossbred gilts (249 d, 123 kg) were administered an intramuscular injection of PG600. Nine days after PG600 administration, gilts were fed 15 mg of altrenogest once daily for 16 d. Twelve gilts (OVU) were administered 200 μg triptorelin …
Evaluating The Effects Of Yeast Cell Wall Component, Phytochemical Oil, And Vitamin E On Sow Antioxidant Status And Growth Performance Of Dam And Offspring, Lily P. Hernandez
Evaluating The Effects Of Yeast Cell Wall Component, Phytochemical Oil, And Vitamin E On Sow Antioxidant Status And Growth Performance Of Dam And Offspring, Lily P. Hernandez
Electronic Theses and Dissertations
Times of high metabolic activity in gestation and lactation, as well as periods of stress at weaning, can lead to greater incidences of oxidative stress in the dam and offspring during the suckling and post-weaning period. Oxidative stress is an imbalance between prooxidant molecules and the antioxidant defense system that can negatively impact growth and/or reproductive performance. The objective of this research was to evaluate the effectiveness of a yeast cell wall component (Citristim, ADM Nutrition, Quincy, IL), peppermint oil, and ɣ-tocopherol in gestation and lactation diets to alleviate the impact of oxidative stress on maternal reproductive and offspring growth …
