Objectives: Study effects of two limit-fed diets formulated to provide two levels of dietary energy and offered at two different intake rates to target similar gains and analyze the efficacy of a novel DNA-immunostimulant administered on arrival.
Study Description: A 56-day pen study was conducted utilizing 370 Angus × Brahman heifers shipped from Florida (1,455 mi) to study the effects of limit-feeding at 2 intakes based on prior research conducted at the Kansas State University Beef Stocker Unit, Manhattan, KS, to achieve similar gains and effects of Zelnate under the dietary conditions.

Many producers have used limit- or programmed-feeding in the past with success, especially during periods of drought when forage is not adequate. In a nutshell, limit- or program-feeding refers to the practice of limiting calves to two-thirds to three-quarters of the dry matter that they can normally consume. This feeding strategy varies greatly with traditional management where calves generally have free-choice access to forage. Traditionally, limit-fed diets have consisted of 80 to 85% whole shelled corn and the remaining balance as a protein supplement. The total amount of the ration delivered is increased every two weeks or so to account for increased body weight gain based upon the desired level of gain.
