Studying Virus Cell Interactiosn: Finding New Ways To Prevent Infectious Bovine Rhinotracheitis In Cattle, C. C.L. Chase, L. J. Braun, J. R. Jessen, D. J. Hurley
South Dakota Beef Report, 1995
lnfectious Bovine Rhinotracheitis (IBR; bovine herpesvirus 1 (BHV-1); Rednose) is one of several cattle respiratory viruses that plays a large role in the shipping fever complex. One of the major problems with IBR is that like other herpesviruses, once animals are infected they carry the virus for life. Investigations in our laboratory have been aimed at understanding how the IBR virus gets into cells. By understanding the mechanism that the virus uses we hope to develop strategies to prevent IBR infection. Our investigations indicate that IBR grows only in actively growing cells like those found in the upper respiratory tract …

Strict Enforcement Of Zero Tolerance: Effect On Carcass Weight And Dressing Percent, D. M. Feuz, J. J. Wagner
South Dakota Beef Report, 1995
Strict enforcement of "Zero Tolerance" regulations in the beef industry is a concern to producers and beef packers. Data on over 1,500 steers, fed and slaughtered over a four period, as part of the South Dakota Retained Ownership Demonstration Project were used to estimate the cost to producers of zero tolerance enforcement. Regression analysis was used to estimate hot carcass weight and dressing percent using the first three years data (time period prior to zero tolerance enforcement). Hot carcass weight and dressing percent were then predicted for year four. On average 13.8 Ib of additional hot carcass weight was predicted …

Can Beef Tallow Make A Comeback?, J. A. Henson, J. R. Romans
South Dakota Beef Report, 1995
A study was conducted to evaluate the use of soybean oil (SBO), beef tallow (TAL) and a 50% SBO 50% TAL blend (50150) in frying three fast-food type products (french fries, chicken nuggets, and beef fingers). Frying french fries in SBO resulted in higher cooking yields (P< .05) than frying in 50150 or TAL. No differences among oils were seen (P>.05) in color development during frying french fries. Consumer taste panelists preferred the flavor and overall acceptability (P< .05) of french fries fried in SBO and 50150 over those fried in TAL. The cooking yield of chicken nuggets was highest (P<.05) for SBO followed by 50150 (P<.05) followed by TAL. Chicken nuggets fried in 50150 were darker (P<.05) than those fried in SBO. Consumer taste panelists could not distinguish (P>.05) between oil types for flavor, crispness, or overall acceptability of chicken nuggets. Beef fingers fried in 50150 were the most red in color (P< .05) followed by TAL (P< .05) followed by SBO. Consumer taste panelists were unable to differentiate between oils (P>.05) for flavor, crispness, or overall acceptability of beef fingers.

South Dakota Beef Report, 1995
The inophore laidlomycin propionate2 (LP) became available in 1995 to improve ADG of cattle fed in confinement. Initial efficacy studies focused on finishing diets and yearling cattle. Limited data are available to quantify the benefits of using LP in calf grower programs. To evaluate LP efficacy for calves, receiving-grower diets based on corn silage were formulated to contain 0, 5.5, or 11 g/T LP and were fed to recently weaned steer calves. Five pens of 10 steers (initial BW = 483 Ib) were assigned to each diet. The grower phase was terminated after 98 days on feed. Final diet ionophore …
Effect Of Anabolic Agents On Marbling In Yearling Crossbred Steers, L. A. Senn, J. J. Wagner
Effect Of Anabolic Agents On Marbling In Yearling Crossbred Steers, L. A. Senn, J. J. Wagner
South Dakota Beef Report, 1995
A total of three hundred and twenty-four crossbred yearling steers were used in a two year study to determine the effects of anabolic agents on carcass characteristics. Steers were fed in a commercial feedlot for an average of 123 days, slaughtered and carcass data were collected. Implanted cattle gained significantly more weight (P< .05) than nonimplanted cattle. Steers that were implanted with Revalor-S gained weight more rapidly (P<.05) than Synovex-S implanted cattle. Implants significantly (P<.05) increased hot carcass weights and rib eye area when compared to nonimplanted cattle and Revalor implanted cattle tended (P= .0564) to have heavier hot carcass weights than Synovex implanted cattle. lmplants did not significantly affect yield grades. Implanted steers had lower (P< .05) marbling scores than control steers. Steers that were implanted with Revalor showed a significant (P<.05) decrease in marbling score when compared to the Synovex groups. The percentage of choice carcasses for no implant, Revalor, and Synovex treatments were 78.85, 58.82, and 67.68, respectively.
