Abstract:
Ipomoea carnea, a swainsonine containing plant, is known to cause a neurologic disease in grazing livestock in Brazil and other parts of the world. To better understand the relative toxicity and nutritional content of I. carnea we investigated swainsonine, calystegine, and crude protein concentrations in leaves of I. carnea on a monthly basis for one year in northern and northeastern Brazil. Swainsonine concentrations were detected at concentrations that could potentially poison an animal throughout the year although there was some variation between months. At one location swainsonine concentrations were generally the highest during the rainy season or the months immediately following the rainy season. Total calystegine concentrations were similar to those reported previously while crude protein concentrations are similar to those found in other Ipomoea species and are such that they may explain why I. carnea becomes desirable to grazing livestock as forage becomes limited during the dry season. |

SUMMARY.
The association between residual feed intake (RFI) and growth, carcass and meat quality traits were investigated using 233 Hereford steers. Individual feed intake, body liveweight, average daily gain and ultrasound measurements were recorded during 70-d post-weaning period to calculate RFI. Steers were categorized into high efficient (<0.5 SD below the RFI mean; 72), medium (mid ± 0.5 SD; 85), and low efficient steers (>0.5 SD above the RFI mean; 76). After the feed intake test, steers grazed on sorghum pasture and oat with corn supplementation during summer and autumn and winter, respectively, until achieving the slaughter weight (with back fat thickness 6.35 mm). During the finishing phase, the efficient steers had some lighter weights (P<0.05) at the start of finishing but achieved the same slaughter weight (P<0.001). Average daily gains during finishing were similar among efficiency groups. No differences were found among groups on ultrasound measures except a slight difference on UBFAT at pre-slaughter between medium and lower efficient (P=0.009). No differences were found among RFI groups for any carcass or meat quality traits. Phenotypic correlations with RFI were close to zero for all traits. These results suggest that increasing feed efficiency by RFI does not lead to unfavorable effect on finishing performance, carcass and meat quality. Larger dataset will allow the estimation of genetic correlation among these traits and the prediction of genetic correlated responses. Keywords: Residual feed intake, beef cattle, growth, tenderness.
