Experiments were conducted during the summers of 2021 and 2022 to evaluate the effects of feeding strategy and shade on growth performance, animal comfort, water usage, apparent diet digestibility, and ruminal fermentation characteristics of growing heifers during periods of heat stress. In Exp. 1, 852 heifers (initial body weight [BW] = 251 ± 13 kg) were assigned to one of 4 treatments: high-energy diet limit-fed at 2.

Article Synopsis
  • - The study aimed to examine how different feeding strategies (ad libitum roughage-based diets vs. limit-fed high-energy diets) affect growth performance, behavior, health, and digestion in growing cattle, along with their impact on feedlot outcomes and carcass traits.
  • - Two experiments involved feeding different groups of crossbred heifers a total mixed ration with varying energy levels, notably contrasting ad libitum feeding with limit-fed approaches, while maintaining consistent diet types throughout the finishing phase.
  • - Findings showed that limit-fed heifers had significantly better gain-to-feed ratios, while ad libitum heifers exhibited longer rumination times, and certain carcass traits were observed based on the weight sorting of heifers before finishing.

Two separate cross-over experiments were conducted to evaluate the effects of incorporating wheat middlings into wet corn distillers grains with solubles (WDGS) on apparent diet digestibility and ruminal fermentation characteristics in growing and finishing diets. In experiment 1, four ruminally cannulated heifers (313 ± 42.9 kg) were limit fed a high-energy growing diet that included WDGS (CON) or WDGS + wheat middlings (CON + WM) at 40% of diet dry matter (DM).

Almond hulls and shells are a by-product of almond production that can be incorporated as a feed ingredient in beef cattle diets. Three experiments were conducted to determine the effects of hammermill screen size on almond hull and shell bulk density and inclusion of ground or non-ground almond hulls and shells in limit-fed growing diets on growth performance, diet digestibility, and ruminal fermentation characteristics of beef cattle. In experiment 1, almond hulls and shells were ground with a laboratory-scale hammermill using no screen, a 11.

Bunk requirements for optimal growth performance of growing calves limit-fed high-energy corn and corn co-product diets have not been widely evaluated. Three-hundred eighty-five crossbred steers (initial body weight = 215 ± 25 kg) were purchased in Texas, transported to the Kansas State Beef Stocker Unit, and weighed at arrival. Steers were stratified by body weight and randomly assigned to 1 of 28 pens containing 12 to 14 head.

Two growth performance studies and two digestibility trials were conducted to evaluate the effects of feeding Enogen Feed Corn silage and corn grain to growing cattle. In Exp. 1, there were a total of four diets offered for ad libitum intake.

Recent research demonstrated that mid- or late-summer prescribed fires can be employed to manage sericea lespedeza () infestations in the Kansas Flint Hills. The effects of prescribed fire applied during the growing season (i.e.

Effects of dietary energy level and intake of corn by-product-based diets on antibody production, acute phase protein response, stress, and immunocompetency of healthy and morbid newly received growing cattle were evaluated. Four dietary treatments were formulated to supply 0.99, 1.
