Synchronizing Estrus And Improving Subsequent Production And Performance With Prostaglandin F2 Alpha And Pregnant Mare Serum Gonadotropin, Bryan Kutz
Masters Theses & Specialist Projects
Two-hundred-seventy-two sows were utilized in two trials to evaluate the effects of prostaglandin and pregnant mare serum on reducing weaning to estrus interval, increasing the degree of estrus synchrony and improving fertility at estrus resulting in improved pregnancy rates and subsequent litter performance. Sows were randomly allotted to treatments. In trial 1, sows were assigned to one of three treatments: T1 (n=18; l0mg of PGF2α /hd 24-48 hrs. after parturition), T2 (n=20; lOmg of PGF 2 α /hd at weaning) and controls (n=20). No differences (P>.05) were observed for survival rate and 21D litter wt. among treated and the …

Evaluation Of Continuous Flow Constructed Wetlands Treating Swine Waste, Stephanie Rivard
Masters Theses & Specialist Projects
The ability for wetlands to purify contaminated water is not a new concept. Natural wetlands have been cleansing water within our environment for ages. After studying the process of natural wetlands the same concept was applied to municipal waste. It is the success of constructed wetlands treating municipal waste that created the new idea for the application of a wetland system to treat wastewater from livestock facilities. Through proper design and management, constructed wetlands may be useful for reducing the nutrient concentration of waste (Rieck el al., 1996). Taking into consideration the higher nutrient loads of livestock waste, the same …
