Roman L. Hruska U.S. Meat Animal Research Center: Reports
Feedlot performance records from the U.S. Meat Animal Research Center feedlot for 1993 through 2000 were analyzed to evaluate the impact of foot rot on ADG and total days on feed. Records from the original pool of 36,755 bull, steer, and heifer calves were sorted so that only steers that had a single foot rot incidence and no other morbidities were included in the data set (7,100 steers). To roughly pattern these data to industry production practices, time of foot rot insult during feeding was divided into 3 production periods: starting (0 to 60 d), growing (61 to 120 d), …

Crossbred, spring-calving cows (yr 1, n = 136; yr 2, n = 113; yr 3, n = 113) were used in a 3- yr experiment to evaluate the influence of supplemental protein prepartum and grazing subirrigated meadow postpartum on pregnancy rates and calf feedlot performance. A 2 × 2 factorial arrangement of treatments was used in a switchback design. From December 1 to February 28, cows grazed dormant upland range in 8 pastures (32 ± 2 ha each). The equivalent of 0.45 kg of supplement/cow per d (42% CP) was provided to half of the cows on a pasture basis …
