Effects of camelina meal supplementation on ruminal forage degradability, performance, and physiological responses of beef cattle

Creator:: Cappellozza, Bruno Ieda
Abstract:: 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...

Management of stockpiled forages and optimal use of supplements by beef cattle while consuming low-quality forages

Creator:: Suverly, Norman A.
Abstract:: Three studies were conducted to evaluate: 1) rotationally grazed forage for late-summer stockpiling; 2) effects of lactation on self-fed supplement intake; and 3) influence of cow age on hand-fed supplement intake. For the first study, treatments consisted of non grazed, 2X and 3X grazed. Crude protein of forage grazed 3X...

Influence of stocking density on grazing beef cattle performance, diet composition foraging efficiency, and diet quality on a late-spring early-summer native bunchgrass prairie

Creator:: Wyffels, Samuel A.
Abstract:: This study evaluated the influence of cattle stocking density on botanical composition of diet, diet preference, and cattle performance on the Zumwalt Prairie in Northeastern Oregon. In each of two years, 192 cow-calf pairs (549.27 kg, BCS = 4.89) and 48 yearling heifers (383.34 kg, BCS = 5.02) were stratified...

Puberty development and reproductive performance in beef heifers fed rations supplemented with Oregon by-product feeds

Creator:: Oswald, Keely E.
Abstract:: In the majority of management scenarios, it is imperative that beef replacement heifers calve at two years of age. In order to achieve this goal, yearling heifers should reach 60 to 65% of their mature body weight by 13 months of age. Feed costs represent 75 to 80% of the...

Daily vs alternate day supplementation of soybean meal or wheat middlings to steers consuming low quality hay

Creator:: Shirley, Tyson R.
Abstract:: 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...

Effects of forage quality and type of protein supplement on intake and digestibility in beef steers and performance of postpartum beef cows

Creator:: White, Jenny J.
Abstract:: 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...

Factors influencing diet composition of beef cattle grazing mixed conifer mountain riparian areas

Creator:: Darambazar, Enkhjargal
Abstract:: Two trials were conducted to evaluate changes in the quantity, quality, and moisture of available forage in the pasture, and shrub utilization by cattle during a 30-d late summer grazing period (Trial 1) and the effect of cow age (experience) on grazing distribution and diet composition (Trial 2) in mountain...

Impacts of Stocking Density on Development and Puberty Attainment of Replacement Beef Heifers

Creator:: Schubach, Kelsey M.
Abstract:: The following experiment presented herein compared growth, physical activity, stress-related responses, and puberty attainment in heifers reared on high- (HIDENS) or low-stocking densities (LOWDENS). Sixty Angus x Hereford heifers were ranked by age and BW (210 ± 2 d and 220 ± 2 kg, respectively) on d 0, and assigned...

Influence of supplement composition on utilization of low-quality, cool-season forages by beef cattle

Creator:: McGuire, Dustin L.
Abstract:: 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...
