LIST OF TABLES
Table page
2-1 Number and weight or volume of dung or urine events per day and surface area
covered (adapted from Haynes and Williams, 1993) .....................................................25
3.1 Chemical composition of excreta analyzed immediately after collection (fresh) and
after storage (stored) for up to 8 d at 40C. Each value is the mean of the analysis of
tw o subsam ples. .............................................................................53
3-2 Herbage mass, N, P, and in vitro digestible organic matter (IVDOM) concentrations
of bahiagrass herbage during excreta collection periods in 2006.....................................59
3-3. Composition of fresh dung from Average and High management intensity source
treatments during three collection periods in 2006. Each value reported is the average
across three subsamples from a composite dung sample. Dung was composite
across replicates within a management intensity treatment, so statistical comparisons
of treatm ent effects are not possible. .......................................................................... 61
3-4. Composition of urine from Average and High management intensity source
treatments during three collection periods of 2006. Each value reported is the
average across three subsamples. Urine was composite across replicates within a
management intensity treatment, so statistical comparisons of treatment effects are
n ot p o ssib le. ............................................................ ................ 6 1
3-5 Nutrients applied to dung treatments in bahiagrass swards. Calculations are based on
chemical analyses of fresh dung (Table 3-3) and a 2-kg fresh weight dung
application to a circle of 30-cm diameter. Data are expressed as kg of N, P, and K
ap p lied h a-1 ............................................................................... 62
3-6 Nutrients applied to urine treatments in bahiagrass swards. Calculations are based on
the chemical analyses of urine (Table 3-4) and a 2-L volume of urine applied to a
circle of 60-cm diameter. Data are expressed as kg of N, P, and K applied ha-1...............62
3-7 Effect of N fertilization on bahiagrass herbage responses for treatments to which no
excreta w as applied. .......................... .......................... .. .. .. ................. 65
3-8 Monthly rainfall totals for 2006 for the research location and the 30-yr average for
Island Grove, FL. Island Grove is located 10 km from the research location and is the
nearest site for which 30-yr data exist. ........................................ .......................... 65
A-1 P values for interactions and main effects on response variables discussed in Chapter
3 ........................................................... ................................. . 1 2 1
A-2 P values for main effects, interactions, and polynomial contrasts for ring number for
dung-treated plots as discussed in Chapter 4. ........................................ ...............122
