Novel cultivars, BarOptima PLUS E34, Jesup MaxQ, and Texoma MaxQ II, possess different endophyte strains that do not have negative effects on cattle but still protect from insect grazing. Our study investigated if different cultivars have different effects on insect dung decomposers such as dung beetles and determined if ergovaline could be detected in cow dung. Ergovaline at 0.04 and 0.27 μg/g was detected only from Kentucky 31 dung samples from 2017 and 2018 collections, respectively. From the 2017 dung collection, we tested Onthophagus taurus oviposition substrate preferences for each cultivar versus dung from uninfected pasture and also larval survival and development for each dung-type. From the 2018 dung collection, O. taurus and Digitonthophagus gazella oviposition substrate preferences, larval survival and development were tested for Texoma MaxQ II versus Kentucky 31 dung-types. Among the four cultivars, for making brood-balls O. taurus preferred dung from Texoma MaxQ II while dung from Kentucky 31 and BarOptima PLUS E34 were avoided. Both beetle species preferred dung from Texoma MaxQ II versus Kentucky 31 pasture. Larval survival was not affected by dung-type with the 2017 samples. However, with the 2018 samples both beetle species had reduced larval survival on Kentucky 31 than on Texoma MaxQ II brood-balls. Development time for O. taurus was shorter for larvae from Texoma MaxQ II versus Kentucky 31 or uninfected dung brood-balls. Adult mass was not affected in the 2017 collection but was reduced in 2018 Kentucky 31 samples when compared with Texoma MaxQ II. Finally, dung beetles can differentiate dung from pastures with different tall fescue cultivars. Novel cultivar, Texoma MaxQ II, provides more benefits for dung beetles. Pasture renovations with Texoma MaxQ II may improve pasture ecology by enhancing dung beetle populations.}, journal={APPLIED SOIL ECOLOGY}, author={Shymanovich, Tatsiana and Crowley, Grace and Ingram, Sammuel and Steen, Chey and Panaccione, Daniel G. and Young, Carolyn A. and Watson, Wes and Poore, Matt}, year={2020}, month={Aug} } @article{rogers_poore_ingram_harmon_2019, title={On-farm demonstrations improve producer understanding of using metsulfuron for tall fescue seedhead suppression.}, volume={97}, ISSN={["1525-3163"]}, DOI={10.1093/jas/skz053.011}, abstractNote={Abstract}, journal={JOURNAL OF ANIMAL SCIENCE}, author={Rogers, Johnny R. and Poore, Matthew H. and Ingram, Sam and Harmon, Deidre}, year={2019}, month={Jul}, pages={5–6} } @article{ingram_poore_poole_2019, title={Renovating toxic-infected tall fescue pastures for profitability, animal performance, and soil health.}, volume={97}, ISSN={["1525-3163"]}, DOI={10.1093/jas/skz053.084}, abstractNote={Abstract}, journal={JOURNAL OF ANIMAL SCIENCE}, author={Ingram, Sam and Poore, Matthew H. and Poole, Daniel H.}, year={2019}, month={Jul}, pages={37–38} } @article{ingram_poore_poole_2019, title={Renovating toxic-infected tall fescue pastures for profitability, animal performance, and soil health.}, volume={97}, ISSN={["1525-3163"]}, DOI={10.1093/jas/skz053.044}, abstractNote={Abstract}, journal={JOURNAL OF ANIMAL SCIENCE}, author={Ingram, Sam and Poore, Matthew H. and Poole, Daniel H.}, year={2019}, month={Jul}, pages={20–20} } @article{ingram_poore_2018, title={Comparison of a Full Season and Early Maturing Forage Sorghum Silage to Corn Silage for Growing Cattle.}, volume={96}, ISSN={["1525-3163"]}, DOI={10.1093/jas/sky027.058}, abstractNote={Brachytic dwarf brown mid-rib forage sorghum varieties are an alternative to corn silage (CS) in certain production systems. Agronomic characteristics, cattle performance and carcass data were collected during this project. Full season forage sorghum (FS,110–115 days), early maturing forage sorghum (ES, 85–89 days), and a full season CS were grown and harvested in a replicated field trial in Bahama, NC. Overall mean yield (kg DM/ha) did not differ (P < 0.12; 6772 kg/ha). Silages contained 30.9, 27.5, 28.3% DM for CS, FS and ES, 68.5, 63.5, 64.7 TDN (% of DM); and 9.6, 8.2, 8.7% CP, respectively. Sixty-six Angus and Angus cross steers (initial BW 329 ± 35 kg) were penned by BW and randomly assigned to one of three treatments. Steers were individually fed ad libitum utilizing Calan gates for a 77-d growing period and a 88-day finishing period. Diets were formulated to 14% CP and were 75% CS, FS or ES and 25% concentrate (DM basis) during growing and 15% CS and 85% concentrate (DM basis) during finishing. Cattle were harvested in Pennsylvania and carcass data were collected. During the growing period, DMI and ADG for the growing period differed among treatments (P < 0.05; P < 0.01) with intake and gain being greatest (9.85 kg/d; 1.95 kg/d) for CS with no difference between FS (8.51kg/d; 1.46 kg/d) and ES (8.69 kg/d; 1.50 kg/d). During finishing, ADG was higher (P < 0.02) for FS (1.80 kg) and ES (1.86 kg) compared to CS (1.66 kg) while finishing DMI did not differ (P < 0.78; 12.10 kg). Feed:gain during the growing period differed (P < 0.01) with CS (4.83) being more efficient than FS (5.90) and ES (6.02). Feed:gain during finishing was lower (P < 0.05) for FS (6.80) and ES (6.65) compared to CS (7.27). Loin eye area did not differ (P < 0.41; 90.3 cm2), but quality grade (17 = low choice and 18 = mid choice) differed (P < 0.03) between CS (18.24) and ES (17.39), but not between CS and FS (17.83, P < 0.17). Brachytic dwarf brown mid-rib forage sorghum silages limited animal performance during the growing period but steers compensated during the finishing period.}, journal={JOURNAL OF ANIMAL SCIENCE}, author={Ingram, S. and Poore, M.}, year={2018}, month={Mar}, pages={31–31} }
