Effects of dietary fat and crude protein on feedlot performance, carcass characteristics, and meat quality in finishing steers fed differing levels of dried distillers grains with solubles1,2

The objective of this experiment was to determine the effects of grain type (rolled corn vs. rolled barley) and oil concentration of dried corn distillers grains plus solubles (DDGS; moderate = 7.9% vs. low = 4.5% ether extract) on site of digestion. Seven ruminally and duodenally cannulated Holstein steers (716 ± 8.9 kg) were used in a 4 × 7 Youden square with experimental periods of 24 d. True ruminal organic matter (OM) and crude protein (CP) digestibility (% of intake) as well as intestinal (% of entering duodenum) and total tract starch digestibility was greater (P ≤ 0.03) in steers fed diets containing barley than in steers fed diets containing corn. Ruminal disappearance and ruminal, intestinal, and total tract OM, CP, and starch digestibility were not influenced (P ≥ 0.11) by feeding diets containing DDGS with differing oil concentration. Total tract lipid digestibility (%) was greater (P < 0.001) in steers fed diets containing moderate-oil DDGS than low-oil DDGS. These data indicate that including a low-oil DDGS, as compared with a moderate-oil DDGS, in finishing diets containing rolled corn or rolled barley does not influence intake or site of digestion of nonlipid components.

This study investigated the effects of Hibiscus (Hibiscus sabdariffa L.) seeds inclusion in diet of cattle. Fifty-five Sudan Baggara bulls were selected and divided into five treatment groups, and fed iso-caloric and iso-nitrogenous experimental diets where groundnut cake was the source of protein in the control diet (0% Hibiscus seeds), while in the other experimental diets, Hibiscus seeds replaced groundnut at a rate of: 25, 50, 75, and 100%. The crude protein was significantly lower in the 100% group than in the control group, whereas muscle fat content was significantly lower in the 25, 75, and 100% groups than in the control group. There were no significant differences between the tested groups for the carcass linear measurements, but there were so for the redness and yellowness color components of the fat, water-holding capacity, and cooking loss. In conclusion, the growth performance and meat quality attributes of the cattle were improved as the level of Hibiscus seeds increased up to 75%, without any adverse effect.
