Two concurrent studies were conducted to evaluate the effect
of selenium (Se) supplementation on beef cows. Trial 1 was designed
to evaluate the safety and efficacy of two intrareticular Se supplementation
delivery systems. Trial 2 was designed to evaluate the
transfer of Se across the placenta and through the colostrum...
Metabolic and performance parameters of beef calves were
compared between Se supplemented (Se) and control (C) dam
treatment groups from known Se deficient cattle. Four
trials were conducted at three locations involving 50,
36, 25 and 39 experimental dam/calf pairs. Se
supplementation was either two 30 gram oral boluses (90%...
Two studies were conducted to determine the effects of zinc (Zn), copper (Cu) and/or selenium (Se) on the humoral immune response of weaned steers fed diets deficient in these minerals. Steers were bled weekly for eight weeks to measure plasma mineral levels. Humoral immune response was measured as antibody response...
Two experiments were conducted to determine the effects of daily (D) vs
alternate day (AD) supplementation of soybean meal (SBM) or wheat
middlings (WM) on forage organic matter intake (OMI), ruminal digesta
kinetics, total tract digestibility, and ADG of steers consuming low quality
forage. In Exp. 1, five Angus x...
Two experiments were conducted to evaluate the effects of forage quality and supplemental undegradable intake protein (UIP) level on intake, digestibility, and performance of beef cattle. In Exp. 1, five ruminally cannulated steers (BW = 456 ± 6 kg) were used in a 6 x 5 incomplete Latin square with...
Two studies were conducted to evaluate the influence of supplement composition on intake and digestibility of a low-quality (< 6% CP), cool-season forage, as well as cow performance. Treatments included a non-supplemented control (CON), corn (approximately 8% CP), corn and urea (LU = corn + 0.09 mg/kg BW urea, approximately...
Two experiments evaluated nutritional management of late-gestating beef cows to enhance offspring productivity. The objective of experiment 1 was to evaluate the effects of organic and inorganic Cu, Mn, Zn, and Co supplementation to beef cows during late-gestation on performance and physiological responses of the offspring. The objective of experiment...
To evaluate the immunologic and metabolic effects of OmniGen-AF® (Phibro Animal Health corporation, Quincy, IL; OG) supplementation in growing beef cattle, we designed three studies using replacement beef heifers (8.5 and 10.5 months of age) and steers supplemented across backgrounding, transition, and finishing periods. In Study 1, the effect of...
Three experiments compared ruminal, physiological, and performance responses of beef steers consuming hay ad libitum and receiving grain-based supplements with (CAM) or without (CO) inclusion of camelina meal. In Exp. 1, 9 steers fitted with ruminal cannulas received CAM (2.04 kg of DM/d) or CO (2.20 kg of DM/d). Steers...
