This study aimed to determine if light exercise increases intake in mature horses, and if horses on ad libitum forage achieve the benefits previously observed. Eight mature, stock-type geldings (594.3±50.5 kg; 12.0±1.7 yr) were adapted to a diet of ad libitum grass hay. Baseline dry matter intake (DMI) was measured for 7 d. Horses then remained idle (CON, n=4) or entered an exercise program (EX, n=4) for 3 weeks. Voluntary DMI was quantified daily. Body weight (BW), heart girth (HG), girth to height ratio (G:H), neck circumference (NC), neck circumference to height ratio (NC:H), rump fat thickness (RF), percent body fat (BF), serum insulin, plasma ghrelin, and plasma leptin were quantified weekly. An oral sugar test was conducted on day 0 and 21, and insulin to glucose ratio (Ins:glc) and 60-min insulin sensitivity index (ISI60) were calculated. Statistical analysis was performed using repeated measures. Insulin, ghrelin, Ins:glc, and ISI60 were not normally distributed, so they were log-transformed for analysis. P≤0.05 was considered significant. The EX group showed no difference in DMI or (log) ghrelin compared to the CON group. The CON group showed increases in BW, RF, and BF, while the EX group showed decreases in HG, G:H, NC, NC:H, (log) insulin, and leptin. EX showed lower (log) Ins:glc than CON after treatment. Overall, light exercise did not alter DMI in mature horses on ad libitum forage, but resulted in improvements in morphometric measurements, (log) Ins:glc, and plasma leptin concentrations, and avoided gains in BW and rump fat.}, number={3}, journal={COMPARATIVE EXERCISE PHYSIOLOGY}, author={Moore, J.

A survey tool including 15 evaluation criteria was available online and at the registration desk of the 2005 Joint Annual Meeting of the American Dairy Science Association and the American Society of Animal Science. The analyzed data set included 47 faculty (41 tenured and 6 tenure-track) with a substantial teaching responsibility from 27 different departments in 25 states. Four criteria were perceived as currently overemphasized: student evaluation of the instructor, student evaluation of the course, authoring peer-reviewed publications, and authoring an undergraduate textbook or book chapter. Nevertheless, more than 50% of respondents reported that these criteria should be used. One criterion emerged as being currently underemphasized: documentation of personal assessment of one's own teaching by preparing a portfolio. The lack of consensus for the remaining 10 items may have reflected substantial differences in institutional practices. The significance of overemphasis or underemphasis of certain criteria varied substantially depending on the respondent's perceived institutional mission. When asked about recognition within their department, 68% of respondents indicated that efforts in teaching improvement were properly rewarded. Respondents doubted the meaningfulness and appropriateness of student ratings tools as currently used. Results also suggested that animal and dairy science faculty placed a higher value on criteria recognizing excellence in teaching based on intradepartmental recognition (e.g., interactions with close-up peers and students) rather than recognition within a broader community of scholars as evidenced by authorship or success in generating funding for teaching. Proposed improvements in the evaluation of teaching for promotion and tenure include 1) providing tenure-track faculty with written guidelines at the time of hiring; 2) ensuring that student ratings tools are reliable and valid; 3) carefully mentoring new faculty within the departmental and institutional culture; and 4) encouraging self-reflection and documentation of attempts to address pedagogical issues in one's own teaching. Educational leaders in doctoral/research universities should promote changes to enhance teaching performance of future faculty graduating from their institutions.}, number={7}, journal={JOURNAL OF DAIRY SCIENCE}, author={Wattiaux, M.

 @article{coverdale_moore_tyler_miller-auwerda_2004, title={Soybean hulls as an alternative feed for horses}, volume={82}, DOI={10.2527/2004.8261663x}, abstractNote={Soybean hulls have been successfully fed to ruminant animals as an economical substitute for hay. This feedstuff is a source of highly digestible fiber that does not contain starch. The purpose of this trial was to evaluate soybean hulls as a replacement fiber in horse diets. Four cecally cannulated Quarter Horse geldings, aged 6 to 10 yr and averaging 502 kg, were used in a 4 x 4 Latin square design with 21-d periods. Diets consisted of alfalfa/bromegrass hay (14.4% CP, 58.1% NDF, 39.1% ADF; DM basis) with the replacement of either 0, 25, 50, or 75% (as-fed basis) unpelleted soybean hulls (13.1% CP, 60.6% NDF, 43.7% ADF; DM basis). Diets were offered at 1.8% of BW (DM) daily and body weights were measured weekly. Cecal samples (90 min after feeding) and total fecal collections (3 d) were taken at the end of each treatment period. Fecal collection bags were emptied every 6 h and 10% of the total amount was frozen for later analysis. Total cecal VFA production increased linearly (P = 0.02) from 70 mM to 109 mM as proportions of soybean hulls in diets increased. Proportions of propionate increased linearly (P < 0.01) with means of 15.7, 18.0, 16.6, and 21.9 mol/100 mol total VFA for the 0, 25, 50, and 75% soybean hulls diets respectively. Proportions of butyrate decreased linearly (P < 0.01) from 5.3 to 3.9 mol/100 mol total VFA. The acetate:propionate ratio decreased linearly (P = 0.02) and cubically (P = 0.03) with means of 4.9, 4.2, 4.9, and 3.3. Apparent digestibility of DM (P = 0.95), OM (P = 0.70), NDF (P = 0.34), ADF (P = 0.31), cellulose (P = 0.93), and hemicellulose (P = 0.25) did not differ among treatments. Apparent digestibility of N decreased linearly (P < 0.01) as concentrations of soybean hulls increased in the diet, and this response was associated with increased cecal fermentation and microbial biomass production. Cecal pH decreased linearly (P = 0.01) from 7.00 to 6.45 as the level of soybean hulls increased, but there was no change (P = 0.68 for the linear effect) for cecal ammonia (mean concentration of 3.85 mM). Soybean hulls stimulate cecal fermentation and are a suitable replacement for hay in equine diets.}, number={6}, journal={Journal of Animal Science}, author={Coverdale, J. A. and Moore, J.

The Control (hay) diet was supplemented with 5.7% soybean meal to bring total dietary protein to 12.5%, by-products were brought to a higher Ca:P ratio with limestone or dicalcium phosphate to make total dietary Ca:P 1.5:1, and soybean meal was added to soyhulls to bring them up to 17% CP (wheat midds = 17% and corn gluten feed = 21% CP). Total DMI (916 g/d+/-57 or 3.2%+/-0.2 BW) did not differ (P > 0.92) among treatments. Initial BW (P = 0.25), final BW (P = 0.48), and ADG (P = 0.56) did not differ for the four treatments. Carcass weight was greater (P = 0.05) for goats fed soyhulls (16.0 kg) or wheat midds (15.6 kg) as compared with goats fed the hay diet (14.5 kg), with carcass weight from goats fed corn gluten feed being intermediate (15.3 kg, SEM = 0.3 kg). Carcass grade did not differ (P = 0.80) and averaged 5.42+/-0.4. Dressing percentage tended (P = 0.12) to be lower for goats fed the hay diet (46.4%) compared with soyhull (48.3%), corn gluten feed (48.3%), or wheat midd (48.8%) diets (SEM = 0.7). Ruminal pH was highest (P < 0.01) for goats fed the hay diet (6.52) and lowest for goats fed wheat midds (6.23) with soyhull (6.41) and corn gluten feed diets (6.35) being intermediate (SEM = 0.05). Digestibility of DM (70.1+/-2.5%), OM (70.3+/-2.6%,), CP (75.5+/-2.0%), GE (68.5+/-2.7%), NDF (68.1+/-3.0%), ADF (65.4+/-3.4%), cellulose (70.1+/-2.9%), and lignin (31.1+/-8.2%) did not differ (P > 0.15). Total ruminal VFA did not differ (86.0+/-6.1 mM, P = 0.59), but acetate:propionate ratio was higher (P < 0.01) for hay (3.1) and soyhull diets (3.3) than for corn gluten feed (2.4) and wheat midd diets (2.4, SEM = 0.11). Ruminal ammonia (mg/100 mL) was lower (P < 0.01) for goats fed hay (15.4) and soyhull diets (11.6) than those fed corn gluten feed (25.2) and wheat midd diets (23.0, SEM = 1.35). Ruminal pH was lower for goats fed the byproducts, but remained above 6. Serum urea nitrogen (mg/100 mL) averaged 21.0+/-1.0 (P = 0.11) with soyhulls tending to be lowest (19.3) and corn gluten feed tending to be highest (22.8). Soyhulls, corn gluten feed, and wheat midds appear to be viable feed ingredients for meat goat diets.}, number={7}, journal={Journal of Animal Science}, author={Moore, J. A. and Poore, M.

In this study, kinetic estimates derived from chromium-mordanted hay or pellets were compared to estimates derived from rare earth markers (Yb, Dy, or Er) applied individually to samples. Twelve yearling rams (52 kg) were given ad libitum access to either hay or a commercial pelleted diet in a crossover experiment. Digesta kinetic estimates were obtained both by nonlinear analysis with two age-independent rates (G1G1) or with gamma time dependency in the fast compartment (G2G1 to G4G1) and by linear regression of natural log transformed fecal marker concentrations (LN method of estimate). Model did not influence total tract (P > .21) or ruminal mean retention times (P > .87). Partitioning of total retention time was similar (P > .21) for the LN, G3G1, and G4G1 models, but the G1G1 and G2G1 models did not adequately fit these data. Nonlinear models overestimated, and LN underestimated, fecal DM output by 9% (SEM = 4.7) for the hay diet. All the nonlinear models provided fecal DM output estimates that were within 5% of actual fecal DM output, but the LN model underestimated it by 18% (SEM = 3.3) for the pelleted diet. Ruminal outflow rate was slower (P < .01) and both ruminal and total mean retention time estimates were longer (P < .01) for Cr than for the rare earths. Despite the marker chosen, relative diet effects were similar. The three rare earth markers gave identical results for digesta kinetic estimates, indicating that they are useful for simultaneous study of more than one ingredient or particle, but direct comparison of rare earth and Cr-mordant passage rates is not advisable.}, number={11}, journal={JOURNAL OF ANIMAL SCIENCE}, author={MOORE, JA and POND, KR and POORE, MH and GOODWIN, TG}, year={1992}, month={Nov}, pages={3528–3540} }
