Abstract
Two studies were conducted to determine the impact of management practices on carcass outcomes in beef cattle production systems: a) the impact of corn supplementation of cows (non-supplemented = 23 vs. supplemented = 24), when fed low-quality forage-based diets at d 110 of gestation for 22 wks on carcass outcomes of their offspring; and b) the effect of a needle-free injection device (NFID = 22) versus needle syringe (NS = 20) on injections site reactions in Angus steers vaccinated and boostered with modified live bovine viral diarrhea. Steers from both maternal treatments did not differ in carcass traits and meat quality (P > 0.05). Injection site lesions were not observed in the carcass tissue from both NF and NS-steers. In conclusion, maternal corn supplementation does not affect the carcass outcomes of the offspring. Also, the use of NF technology does not cause tissue damage and would help to eliminate the presence of broken needles that can occur with NS injections.
