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...
Studies were conducted over a 10-year period to determine the feasibility
of supplementing lactating cows being wintered on native meadow hay. The
interaction between cow feed levels and creep feeding of calves was also investigated.
Results show that a full feed of meadow hay to the cows and no creep...
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...
Sheep and cattle dietary preferences were determined on tall fescue-subclover ( Festuca arundinacea-Trifolium subterraneum) and
perennial ryegrass-subclover (Lolium perenne-Trifoliuni subterraneum)
pastures in western Oregon during the spring and summer periods
of 1964 and 1965. Esophageal-fistulated Willamette ewes and
Hereford and Hereford-Angus yearling cattle were grazed separately
on each pasture mixture...

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...
