All animals in both trials were offered ad libitum a total mixed ration (TMR) supplemented with concentrates containing the YE.
Gozho et al. [ 5] induced SARA in dairy cows by replacing 25% (DM basis) of the total mixed ration containing 44% concentrate with a concentrate made of 50% wheat and 50% barley.
One group was fed a control diet comprising 65% forage and 35% mixed concentrate (low concentrate group, LC), while the other group received a high-grain diet containing 65% mixed concentrate and 35% forage (high concentrate group, HC).
Steers were fed a total mixed ration containing dietary concentrate to corn silage ratio of 50 50 on a DM basis.
Dietary treatments consisted of 1) milk replacer control, 2) pectin-based concentrate, 3) neutral detergent fiber-based concentrate, 4) starch-based concentrate, and 5) mixed concentrate (equal amounts of concentrates of treatments 2, 3, and 4).
Prothrombin complex concentrates contain the vitamin K-dependent coagulation factors.
Animals were offered a completely mixed diet containing grass silage and concentrates, with the level of concentrate in the diet either 30 or 70% of dry matter (DM).
When dairy cows were fed a control diet containing 70% of forage and 30% mixed concentrates (DM basis), a high grain diet (38% wheat-barley pellets, 32% mixed concentrates, and 30% of forages), or a diet containing alfalfa pellets (45% of mixed concentrates, 32% of alfalfa pellets, and 23% of other forages), the ruminal LPS concentrations were 8,333, 124,566, and 18,425 EU/mL, respectively [ 7].
Multiparous Holstein cows were assigned at parturition to a total mixed diet containing 33% corn silage, 17% chopped alfalfa hay, and 50% concentrate mix on a DM basis for 10 wk.
Cows were fed a total mixed ration containing 36.1% corn silage, 8.3% alfalfa hay, and 55.6% concentrate (dry matter basis).
