The aim of this study was to evaluate the fatty acid composition of intramuscular fat and the vitamin E content of beef from different production systems. Four cattle production systems were used: cattle reared under intensive conditions and fed concentrate (INT1) from Spain, cattle raised at pasture and supplemented with concentrate (SUP1) from the United Kingdom, cattle raised at pasture and on corn silage (SUP2) from Germany and cattle reared under extensive conditions slaughtered at two and three years old (EXT2 and EXT3) from Uruguay. The highest proportion and content (mg per 100 g of muscle) of linoleic acid (C18:2n-6) and arachidonic acid (C20:4n-6) and the lowest saturated fatty acids (SFA) was found in INT1 beef. In contrast, beef reared under extensive conditions showed the highest proportion and content of linolenic acid (C18:3n-3), docosapentaenoic acid (DPA, C22:5n-3) and eicosapentaenoic acid (EPA, C20:5n-3), and SUP1 and SUP2 beef showed the highest level of palmitic acid (C16:0) and SFA. Beef from intensive system (INT1) had the lowest P/S (PUFA/SFA) ratio, whereas beef from extensive system (EXT2 and EXT3) had the lowest n-6/n-3 ratio. The results of the PCA (principal components analysis) of fatty acid composition showed that beef from intensive system (INT1) was clearly differentiated
from the other meats and was located with the C18:2n-6 and C20:4n-6 and the n-6/n-3 ratio. EXT2 and EXT3 beef were located with C18:3n-3 and long chain fatty acids. Beef from extensive systems had the highest concentration of vitamin E (3.91 mg a-tocopherol/kg muscle) MenosThe aim of this study was to evaluate the fatty acid composition of intramuscular fat and the vitamin E content of beef from different production systems.

Abstract. The objective of the present study was to evaluate two energy intake levels during the last third of gestation of beef cows, placental characteristics, ethological and morphometric variables of their female calves were evaluated. Thirty-one British multiparous cows, inseminated at fixed time and carrying females were assigned on Day ?90 (Day 0=delivery) to two levels of energy intake until delivery: i- 125 % of the requirements (ALTA? n=15) and ii- 75 % of the requirements (BAJA? n=16). In the cows, live weight (PV), body condition score (CC),
concentration of unesterified fatty acids (AGNE) and insulin were recorded. Placenta (weight, number of cotyledons and placental efficiency) was characterized and morphometric and behavioural measures were evaluated within the first 24 hours of calf life. At calving, BAJA cows had a higher concentration of AGNE (0.45 ± 0.03 vs 0.27 ± 0.03 mmol/L, P<0.01) and lower insulin (8.83 ± 0.73 vs 10.88 ± 0.71 µIU/mL, P<0.03), as well as lower PV (478 ± 15.4 vs 521 ± 11.8 kg, P<0.01) and CC (3.9 ± 0.08 vs 4.5 ± 0.06 u? P<0.01) compared to ALTA cows. The characteristics evaluated in the placentas were not affected by treatments, nor was the PV of the calves at birth. In the same way,
none of the morphometric or behavioural variables were significantly affected by the treatments. In the present experiment, the undernourished cows mobilized body reserve during the last third of gestation to protect the integrity of their offspring? this was verified by the absence of differences in the parameters evaluated. Possibly, cows grazing native pastures develop mechanisms of accumulation and mobilization of body reserves that allow them, at least for the conditions of the present study, to overcome periods of forage shortage as an adaptation strategy.
Resumen. El objetivo del presente trabajo fue evaluar dos niveles de energía en la dieta de vacas para carne durante el último tercio de gestación, sobre características de la placenta, variables etológicas y morfométricas de sus hijas. Treinta y una vacas británicas multíparas, inseminadas a tiempo fijo y gestando hembras fueron asignadas el Día ?90 (Día 0=parto) a dos niveles de consumo de energía relativo a los requerimientos de mantenimiento hasta el parto: i- 125 % (ALTO? n=15) y ii- 75 % (BAJO? n=16). En las vacas se registró peso vivo
(PV), condición corporal (CC), concentración de ácidos grasos no esterificados (AGNE) e insulina. Se caracterizaron
las placentas (peso, número de cotiledones y eficiencia placentaria) y se evaluaron medidas morfométricas y comportamentales de las terneras en sus primeras 24 horas de vida. Al parto, las vacas de BAJO presentaron mayor concentración de AGNE (0.45 ± 0.03 vs 0.27 ± 0.03 mmol/L, P<0.01) y menor de insulina (8.83 ± 0.73 vs 10.88 ±0.71 µIU/mL, P<0.03), así como menor PV (478 ± 15.4 vs 521 ± 11.8 kg, P<0.01) y CC (3.9 ± 0.08 vs 4.5 ± 0.06 u? P<0.01) respecto a las vacas de ALTO. Las características evaluadas en las placentas no fueron afectadas por los
tratamientos como tampoco lo fue el PV de las terneras al nacimiento. De la misma forma, ninguna de las variables
morfométricas ni comportamentales fue afectada significativamente por los tratamientos. En el presente experimento, las vacas subalimentadas movilizaron reserva corporal durante el último tercio de gestación pararesguardar la integridad de sus crías verificado por la ausencia de diferencias en los parámetros evaluados. Posiblemente las vacas pastoreando campo nativo desarrollen mecanismos de acumulación y movilización de reservas corporales que les permite, al menos para las condiciones del presente estudio, sobreponerse a los períodos de escasez de forraje como estrategia de adaptación.
