Growth performance and carcass characteristics of choline supplemented feedlot steers
The effects of dietary choline supplementation, in the form of 60% choline chloride, were evaluated on thirty head of Brahman-influenced steers. Steers were fed to slaughter at two different endpoints, one being after 120 days on feed and the other after 140 days on feed. Analysis was performed for effects of both choline supplementation, days on feed, and the interaction between choline supplementation and days on feed. The linear effect of initial weight was also tested for significance and included in the analysis of those traits which were effected (P < .001). The results of the analysis indicate that dietary choline supplementation does not significantly effect carcass quality or marbling scores (P < .05). Growth performance effects for average daily gain and final weight were also not significantly effected by dietary choline supplementation (P < .05). Dietary choline supplementation did have a significant effect in reducing ribeye area and kidney, pelvic, and heart fat (P < .05).
