Restricted grain supplementation effects on animal performance, carcass weight, meat quality and fatty acids profile were investigated on finnishing steers under grazing conditions, focused on their influences on human health. During 194 days (from June to December 2008), 24 Uruguayan Hereford steers were assigned to different treatments (T) considering herbage allowance (HA) and level of grain (ground sorghum) supplementation (G) according to the liveweight (LW) of the animals.
Treatments were a combination of pastures (P) and G levels, where T1 (P at 4% HA of LW); T2 (P at 2% HA of LW + G at 0.8% of LW); T3 (P at 2% HA of LW + G at 1.6% of LW) were applied. It was proven that increasing levels of G supplementation improved animal peformance and carcass weight, having minor influences on meat quality traits (pH, meat colour, tenderness). Intramuscular fat was not affected by T. The concentrations of linolenic (18:3 n-3) followed the pattern of T1=T2>T3. In the
case of linoleic acid (18:2 n-6), T2 had higher concentrations than T1 and T3. The long chain arachidonic (20:4 n-6), eicosapentaenoic-EPA (20:5 n-3) and docosapentaenoic-DPA (22:5 n-3) fatty acids were significant lower for T3 in comparison with T2. Human health recommendations for PUFA:SFA and ?6:?3 ratios are over 0.45 and below 4.0, respectively. The PUFA:SFA ration fell into the range of 0.22 to 0.36, while ?6:?3 ratio was always below 0.4. However, T2 had better PUFA:SFA
ratio than the rest of the treatments, while T1 produced the best ?6:?3 ratio. It is highlighted the potential utilization of restricted amounts of grain supplementation G in beef finishing system under grazing conditions for increasing productivity as well as promoting healthy meat. This proposal could have productive and economical benefits for livestock farmers in extensive regions of Uruguay and for the beef industry.
