Cytokine supplemented maturation medium improved development to term following somatic cell nuclear transfer (SCNT) in cattle

Jacob Keim, Ying Liu, Misha Regouski, Rusty D. Stott et autres

CONTEXT: In vitro maturation is an important process in the production of embryos. It has been shown that three cytokines, fibroblast growth factor 2, leukemia inhibitory factor and insulin-like growth factor 1 (FLI), increased efficiency of in vitro maturation, somatic cell nuclear …

PSI-19 Influence of cattle breed and forage type on organic dairy heifer performance

Sawyer Fonnesbeck, Kara J Thornton, Blair L. Waldron, Rusty D. Stott et autres

Abstract Many breeds of dairy cattle exist, but questions remain about their relative performance within exclusively forage-based systems in the United States. This paucity of data is especially apparent in relation to heifer development, which is the second largest expense on most …

PSXIII-7 Effects of different organic pastures on dairy heifer rumen fluid characteristics

Reganne K Briggs, Jacob Hadfield, Marcus F. Rose, Rusty D. Stott et autres

Abstract This study investigates the effects that different forages in a rotational grazing system have on pH and VFA proportions of rumen fluid in organically raised dairy heifers. In 2018, 81 yearling Jersey heifers were assigned to one of nine treatments, including …

The effects of organic grass and grass-birdsfoot trefoil pastures on Jersey heifer development: Heifer growth, performance, and economic impact

Jacob Hadfield, Blair L. Waldron, S. Clay Isom, Ryan Feuz et autres

Dairy heifers developed in certified organic programs, especially those utilizing pasture-based management schemes, have lower rates of gain than heifers raised in nonorganic confinement production systems in temperate climates, such as in the Intermountain West region of the United States. This study …

1 Effect of cytokine-supplemented maturation medium on bovine somatic cell nuclear transfer embryo development

Jacob Keim, Y. Liu, Misha Regouski, Rusty D. Stott et autres

In vitro maturation is an important process in the in vitro production of embryos. It has been shown recently that 3 cytokines: fibroblast growth factor 2 (FGF2), leukemia inhibitory factor (LIF), and insulin-like growth factor 1 (IGF1), increase the efficiency of IVM, …

Fatty Acid Metabolism on Pasture- and Feedlot-Finished Cattle

Cuk Tri Noviandi, Robert Edwin Ward, J.-S. Eun, Dale R. ZoBell et autres

Feeding high-grain diets to finishing beef cattle results in high proportions of saturated fatty acids (SFA) in the beef, which is considered to confer negative impacts on human health. In contrast, pasture-finished cattle produce lower proportion of SFA, greater n-3 and less …

355 Effects of lactation and negative energy balance on endometrial expression of selected transcripts of Holstein dairy cows at day 7

Sameer Alhojaily, Rusty D. Stott, Heloísa M. Rutigliano, John R. Stevens et autres

Dairy cows often experience a state of negative energy balance (NEB) during the first few months of lactation, resulting in dramatic fluctuations in circulating levels of hormones and metabolites that may have a negative impact on uterine environment and overall cow fertility. …

Urine volume and nitrogen excretion are altered by feeding birdsfoot trefoil compared with alfalfa in lactating dairy cows1

Mohammad Ghelichkhan, J.-S. Eun, Rachael G. Christensen, Rusty D. Stott et autres

Legumes that contain condensed tannins may have lower ruminal protein degradation than alfalfa. The present study investigated the effects of feeding birdsfoot trefoil (Lotus corniculatus L.) hay on lactational performance and N utilization and excretion. Eight multiparous Holstein cows in midlactation (150 …
