Table 4.
Plasma concentrations of saturated and monounsaturated fatty acids (µg/mL of plasma) in forage-fed beef cows receiving no supplementation (NOSUPP; n = 6 pens), or receiving a molasses-based supplement enriched with Ca salts of soybean oil (24.7% of dry matter; Essentiom, Church and Dwight Co., Inc., Princeton, NJ) via self-fed low-moisture block (LMB; n = 6 pens) or hand-fed granular concentrate daily (CONC; n = 6 pens). Supplement treatments were provided from days 0 to 42 of the experiment1
