Effect of induced hypocalcemia in nonlactating, nonpregnant Holstein cows fed negative DCAD with low, medium, or high concentrations of calcium

Autor: Marisa Klister, Austin P Prichard, Dennis Nuzback, Adrienne A. Cheng, Laura A Amundson, P.M. Crump, S. S. Bascom, Laura L. Hernandez, Angela D Rowson, Ken P Zanzalari, Collin E Wimmler, Samantha R. Weaver

Publikováno v: Journal of Animal Science. 96:5010-5023

The main objective of this study was to determine how feeding different dietary calcium (Ca) concentrations in combination with a negative dietary cation–anion difference (DCAD) would affect the cow’s response to induced hypocalcemia. We conducte

Publikováno v: Journal of Dairy Science. 100:5434-5448

The objectives of this study were to measure performance responses and to evaluate indictors of N utilization in late-lactation cows fed diets with incremental reductions in crude protein (CP) concentration. Holstein cows (n = 128; 224 ± 54 d in mil

Short communication: The effect of ruminal administration of 5-hydroxy-l-tryptophan on circulating serotonin concentrations

Autor: Laura L. Hernandez, M.K. Connelly, P.M. Crump, Aaron M. Marshall

Publikováno v: Journal of dairy science. 103(11)

The monoamine serotonin has been shown to regulate peripartal calcium homeostasis in multiparous cows and be a possible mitigation tool for hypocalcemia. Increasing circulating serotonin concentrations via prepartum intravenous (IV) administration of

Low Dietary c9t11-Conjugated Linoleic Acid Intake from Dairy Fat or Supplements Reduces Inflammation in Collagen-Induced Arthritis

Autor: P.M. Crump, Jeffrey W. Bishop, Mark E. Cook, Shane M. Huebner, Jake M. Olson, James P. Campbell

Publikováno v: Lipids. 51:807-819

Dietary cis-9,trans-11 (c9t11) conjugated linoleic acid (CLA) fed at 0.5 % w/w was previously shown to attenuate inflammation in the murine collagen-induced (CA) arthritis model, and growing evidence implicates c9t11-CLA as a major anti-inflammatory

Our objective was to evaluate the effect of a second PGF 2α treatment and duration of an Ovsynch protocol that included a progesterone-releasing intravaginal device (PRID) on progesterone (P4) concentrations and pregnancies per artificial inseminati

Critical reevaluation of the 4-(dimethylamino)cinnamaldehyde assay: Cranberry proanthocyanidin standard is superior to procyanidin A2 dimer for accurate quantification of proanthocyanidins in cranberry products

Autor: Jessica Parker, Xin Chen, Christina Khoo, Jannie P.J. Marais, P.M. Crump, Nathan J. Chesmore, Christian G. Krueger, Jess D. Reed, Dhanansayan Shanmuganayagam

Publikováno v: Journal of Functional Foods, Vol 22, Iss, Pp 13-19 (2016)

The 4-(dimethylamino)cinnamaldehyde (DMAC) assay is currently used to quantify proanthocyanidin (PAC) content in cranberry products. In a multi-operator/multi-day study design, a cranberry proanthocyanidin (c-PAC) standard was compared to procyanidin

Effect of ensiling time and exogenous protease addition to whole-plant corn silage of various hybrids, maturities, and chop lengths on nitrogen fractions and ruminal in vitro starch digestibility

Autor: Randy D. Shaver, P.M. Crump, Luiz F. Ferraretto

Publikováno v: Journal of Dairy Science. 98:8869-8881

The objective of this study was to evaluate the effects of ensiling time and exogenous protease addition on soluble CP (% of CP), ammonia-N (% of N), and ruminal in vitro starch digestibility (ivSD) of whole-plant corn silage (WPCS) from 3 hybrids, 2
