Evaluating new ventilation rate and evaporative cooling for modern swine production
Heat and moisture production (HMP) rates of animals are used for calculation of ventilation rate (VR) in animal housing. New swine HMP data revealed considerable differences from previously reported data. This project determined new design VR for swine barn and evaluated differences from previously …

Evaluation of Constructed Wetlands for the Waste Management of a Large Scale Swine Production Unit
… the levels of the Fecal Coliform Bacteria from a swine operation was evaluated. The indicator of proper waste purification will be the result of testing for the following: ammonia nitrogen, nitrate nitrogen, total phosphorus, total suspended solids, dissolved solids, dissolved oxygen, biological …

An Assessment of the Discommodity Effects of Swine Production on Rural Property Values: A Spatial Analysis
It is also important to have a spatially balanced sample when the range of impact from a source is spatially limited. Stratified area sampling, taking all observations within a certain distance band, performs better than random sampling. Finally, spatial non-linearities in property value arising …

Essays on Organizational Form and Function in Agricultural Production Alliances
… choice of organizational form for industrialized swine production. Using models derived from various theories of the firm an integrated organizational form is shown to be more efficient in the long run relative to network (alliance) production. Secondly, system dynamics models are used to model …

Determining the outcomes of vaccination against Mycoplasma hyosynoviae by identifying optimal application times
A swine-specific bacterial microorganism that is commensal in nature but has also been proven to be pathogenic and cause disease is Mycoplasma hyosynoviae (M. hyosynoviae). The most common clinical sign associated with M. hyosynoviae infection is lameness in growing and finishing pigs and breeding …

Dynamic system modeling and decision support for grow-finish swine barn operation
Understanding both swine growth performance and swine barn management under different conditions is essential to evaluate the swine production system. The integrated effect of swine growth and swine barn management is difficult to investigate because of their complex relationships. To estimate the …

Development of dynamic computational model for an integrated farming system
… This dynamic system model for IFS integrates swine production, swine barn energy requirements, anaerobic digestion (AD) processes, anaerobic digester heat requirements, combined heat and power (CHP) production, and nitrogen requirements for crop production. In this system, swine manure is …

Evaluation of a mechanical foam mitigation device
Foam production in deep-pit swine manure storages has become a significant problem for the swine industry in recent years. Foaming creates management and safety issues for swine producers, including increased risk of flash fires or explosions and reduced manure storage capacity. Due to these …

Productivity variation and group optimization
… but never formalized its treatment in a production economics setting. In group production, individuals enter the production process and exit the production process at the same time. In this dissertation, I show that the effect of Jensen's inequality must be formally accounted for in a …

Detecting estrus in sows using a robotic imaging system and neural networks
… with the growth of the population. Traditional swine farming presents disadvantages such as low breeding efficiency and high labor cost. Estrus detection is crucial to reproductive management of sows. Due to the longevity of the sperm and eggs, achieving timely and accurate estrus detection can …

Effect of sire line and rate of gain on pork quality
… selection is a critical factor in modern day swine production as it has the ability to influence characteristics that affect the financial stability of the producer and packer while concomitantly influencing the eating experience of the consumer. Pietrain pigs are often utilized in swine …

The effect of antibiotic treatment on Haemophilus parasuis colonization, disease and immunity
… source of economic losses in commercial swine production systems. The success of controlled exposure in the field suggests that early exposure (colonization) with pathogenic H. parasuis protects pigs from Glasser's disease. However, little is known about the immune response that is …

Maternal programming of piglet microbiomes
… factors to positively influence pig health and production without the need to resort to individualized interventions such as dietary antimicrobials later in life. The objective of this thesis was to investigate the manipulation of several different maternal factors in swine production systems in …
