Contenido : |
The use of restricted grain supplementation effects on animal performance, carcass weight, meat quality traits and fatty acids profile of intramuscular fat
was researched on finnishing steers under grazing conditions. The experiment lasted for 150 days, from 11th June to 9th December 2007, where twenty four
Uruguayan Hereford steers were assigned to different treatments (T) considering herbage allowance (HA) on pasture (P) and grain (ground sorghum) supplementation
(G) according to the liveweight (LW) of the animals. The treatments applied were a combination of P allowances and unique G supplementation level, being T1 (P at 4%
HA of LW); T2 (P at 2% HA of LW without G) and T3 (P at 2% HA of LW + G at 0.8% of LW). The increase in HA and G increased animal performance, ribeye area,
carcass weight and fatness, and pistola cuts and had limited influences on meat quality traits (marbling, pH, meat colour, tenderness). Intramuscular fat was affected
by T (T3>T1>T2; P<0.01). The concentrations of linolenic (18:3 n-3) was higher for P treatments (T1=T2>T3; P<00.1). However, linoleic acid (18:2 n-6)
concentration followed the pattern of T2>T1=T3 (P<0.01). The trend in the long chain arachidonic (20:4 n-6), eicosapentaenoic-EPA (20:5 n-3) and decosapentaenoic-DPA (22:5 n-3) was similar between treatments, where the concentration was significantly higher for T2 in comparison with T1 and T3 (P<0.01),
being, in general, T1 higher than T3. The CLA, SFA, MUFA concentrations did not vary between T. However, levels of PUFA were T2>T1>T3 (P<0.01). 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 0.11 to 0.25 (T2>T1>T3;
P<0.01), while ?6:?3 ratio was always below 4.0, ranged between 1.28 and 1.79, being T3>T1=T2 (P<0.01). This research group showed the benefits of using limited G
levels in promoting animal performance, productivity and carcass and meat quality traits under grazing conditions without affecting sustantially the wellknow
advantage of grass-fed beef for human health. MenosThe use of restricted grain supplementation effects on animal performance, carcass weight, meat quality traits and fatty acids profile of intramuscular fat

En los últimos años, en el sur de la provincia de Santa Fe, como en el resto de la región maicera típica se produjo un paulatino desplazamiento de los cultivos productores de rastrojo voluminoso, como el maíz y sorgo granífero, por el cultivo de soja. Si bien este cultivo es el más rentable, de menor riesgo y de mayor retorno por capital invertido, a largo plazo este proceso no es la mejor alternativa ya que se contrapone con un desarrollo agropecuario sustentable. |
