Effects of cottonseed meal supplementation and wheat pasture maturity on forage intake and digestion characteristics of cows grazing winter wheat pasture

The influence of RFI classification and cow age on body weight and body condition change, supplement intake, and grazing behavior of beef cattle winter grazing mixed-grass rangelands

“…Cows were also grouped into six age classes (1, 2, 3, 4, 5 to 7, and ≥8 yr old) to evaluate the effects of RFI, and age on average daily individual supplement intake (g ∙ kg body weight −1 ∙ d −1 ), coefficient of variation (CV) of supplement intake (%), intake rate (g ∙ min −1 ), as well as changes in body weight (kg) and condition. Additionally, each year, cows were stratified by age (2, 5, and 8 yr olds) and RFI (high, low) and within strata, randomly assigned to wear 1 of 30 Lotek 3300LR GPS collars (Lotek Engineering, Newmarket, ON, Canada; five collars per RFI class within age class; Parsons et al, 2019 ).…”
