Utilization of phosphorus and other minerals from broiler litter and swine waste
… absorption of P and certain other minerals from swine waste and broiler litter. The effect of source and level of P on rumen cellulytic bacterial populations was also determined. Animals were fed a low P basal diet until serum inorganic P averaged 5.5 mg/dl, then randomly assigned to the …

Swine waste lagoon effluent: its nutrient supplying potential and efficiency in corn production
… to evaluate the variability of nutrients in swine waste lagoons, to determine the effects of swine lagoon effluent on yield and nutrient concentrations of corn, and to study the downward movement of elements in surface applied effluent. Chemical analyses showed that elemental concentrations …

Fermentation, utilization, and palatability of swine waste ensiled with various proportions of ground orchardgrass hay or ground corn grain
The feasibility of ensiling swine waste (primarily feces) with ground orchardgrass hay or with ground corn grain was determined by mixing and ensiling the following proportions of each (as is basis): 80:20, 70;30, 60:40, 50:50, 40:60, 30:70 and 20:80. In the swine waste-orchardgrass hay trials, …

Eicosapentaenoic Acid (EPA) from Porphyridium Cruentum: Increasing Growth and Productivity of the Microalgae for Pharmaceutical Products
… possible growth of P. cruentum in ultra-filtered swine wastewater was also evaluated in this study. P. cruentum was grown in different waste dilutions (total nitrogen concentrations of 12.4, 49.4, 82.4 and 115.3mg/L) to achieve the optimum nutrient condition for producing EPA. Various salinities …

Evaluation of Macrolide-Lincosamide-Streptogramin B Antimicrobial Resistance at Swine Farms
… B (MLSB) antimicrobial resistance at swine farms were quantified. A variation of fluorescence in situ hybridization (FISH) was developed to detect the methylation of a specific adenine residue (A2058 in Escherichia coli) in the 23S rRNA responsible for MLSB resistance. A robust and …

Production and Degradation of 4-Ethylphenol in <i>LACTOBACILLUS SP. </i>pep8 Cultures and in Blended Swine Lagoon Enrichments
<p>4-Ethylphenol (4-EP) is a malodorant of swine waste and is derived from a component of lignin called p-coumaric acid (p-CA). The production of 4-EP from lignin in swine waste is untested. Additionally, the effect of Fe (III) on 4-EP levels is unknown. Four experiments were performed to determine …
