Filename: Integrated Crops Livestock Beef Data 2017.xlsx Short description: Beef Data -------------------------- METHODOLOGICAL INFORMATION -------------------------- 1. Description of methods used for collection/generation of data: Thirty bull calves were born at the WCROC from March to May 2015 and assigned to one of three replicated breed groups at birth. Breed groups were (1) purebred Holstein (HOL, n = 10), (2) crossbreds comprised of Montbéliarde, Viking Red, and Holstein (MVH, n = 10), and (3) crossbreds comprised of Normande, Jersey, and Viking Red (NJV, n = 10). At four days of age, calves were offered starter grain ad libitum and were weaned when calves consumed 0.91 kg of starter grain per day at an average age of 10 weeks of age. After weaning, steers were relocated to a loose confinement barn, remained in their respective groups, and were fed an organic total mixed ration diet consisting of organic corn silage, alfalfa silage, corn, soybean meal, and minerals from the time of weaning until 25 April 2016. During spring of 2016, dairy steers grazed either WR (n = 15) or WW (n = 14) cover crops in the vegetative state. The WR and WW were planted on 10 September 2015 on two adjacent 4-ha plots. On 25 April 2016, each replicate breed group was randomly assigned to either WR or WW and rotationally grazed until 13 June 2016 for 7 weeks with supplemented free-choice certified organic minerals. The WR and WW cover crops were balanced for steer breed. 2. Methods for processing the data: 3. Instrument- or software-specific information needed to interpret the data: SAS 9.4 Statistical Analysis Software 4. Standards and calibration information, if appropriate: 5. Environmental/experimental conditions:The current study was conducted at the University of Minnesota West Central Research and Outreach Center (WCROC) organic dairy in Morris, Minnesota. 6.
