Stay Strong (SS, Ralco Inc., Marshall, MN) is a blend of essential oils (EO) and prebiotic fiber technologies designed to promote immunity and stimulate appetite, helping to diminish health challenges and stresses experienced by newborn calves. Current feeding inclusion rates are unknown to achieve optimal performance in the first 8 weeks of life. The study objectives were to determine the optimal feeding inclusion rate of SS when added to milk replacer (MR) to achieve optimal performance when compared to a yeast cell wall (YCW). One hundred Holstein calves were blocked by birth date and randomly assigned to 1 of 5 …

An Evaluation Of Feeding A Blend Of Essential Oils And Cobalt Lactate To Lactating Dairy Cows, Olivia Jayne Kuester
Electronic Theses and Dissertations
The objective of this study was to determine if the inclusion of a blend of essential oils and cobalt lactate (EOC) in the diet of lactating dairy cows could result in improved nutrient utilization and lactational performance in addition to assessing the application of EOC to control feed mycotoxins and spoilage. The trial was conducted in two experimental periods (Phase 1 (P1) and Phase 2 (P2)) on a commercial dairy in southwest Minnesota equipped with two robotic milking units. Phases 1 and 2 were cross over design trials with two pens. Cows were housed in two freestall pens (57 ± …
