Effects of Cultivar and Distillers Grains Supplementation on Grazing and Subsequent Finishing Performance of Stocker Steers Grazing Tall Fescue Pasture
Four hundred thirty-two yearling steers grazing tall fescue pastures were used to evaluate the effects of fescue cultivar and dried distillers grains (DDG) supplementation during the grazing phase on available forage, grazing gains, subsequent finishing gains, and carcass characteristics. Fescue cultivars evaluated were highendophyte ‘Kentucky 31’ and low-endophyte ‘Kentucky 31,’ ‘HM4,’ and ‘Ma...
متن کاملEffects of selected endophyte and tall fescue cultivar combinations on steer grazing performance, indicators of fescue toxicosis, feedlot performance, and carcass traits.
Five tall fescue [Lolium arundinaceum (Schreb.)] pastures [wild-type 'Kentucky-31' with 78.0% of plants infected with ergot alkaloid-producing endophyte Neotyphodium coenophialum (KY31 E+), 'Jesup' AR542 endophyte-infected contaminated with 30.3% tall fescue containing ergot alkaloid producing-endophyte (Jesup AR542 E+); 'GA-186' AR584 endophyte-infected contaminated with 11.8% tall fescue cont...
متن کاملEffect of domperidone supplementation of fescue-fed heifers on plasma and follicular fluid fatty acid composition and oocyte quality.
This study continues a series of investigations evaluating fescue endotoxin exposure in beef heifer production. The objectives were to evaluate fatty acid compositions in plasma and follicular fluid, and to assess oocyte quality from cattle fed fescue diets. The ability of domperidone, a dopamine antagonist, to mitigate these variables was also assessed. Thirty heifers were divided into 3 treat...
متن کاملImpact of endophytic fungi on seed and seedling characteristics in tall and meadow fescues
Tall fescue and meadow fescue are naturally infected with fungal endophytes, Neotyphodiumcoenophialum and Neotyphodium uncinatum, respectively. Seed traits are an important measureof the effects of the endophytic fungi which has been less addressed. In this study we usedendophyte-infected (EI) and endophyte-free (EF) clones of tall and meadow fescue genotypes inthe field to investigate the effe...
متن کاملEffect of endophyte type on carcass traits, meat quality, and fatty acid composition of beef cattle grazing tall fescue.
Fourteen Hereford steers were used to compare carcass traits, meat quality, and fatty acid composition of beef from cattle grazing tall fescue infected with either wild-type (E+; n = 6) or novel, nil ergot alkaloid (AR542; n = 8) endophyte for 209 d. Average daily gain, live weight, and HCW were greater (P < 0.05) for AR542 cattle than for E+. No differences in LM color or pH were observed betw...
