Summary: The effect of condensed tannins (CT) in the pasture (Lotus uliginosus cv. E-Tanin) and/or quebracho and chestnut extracts on lamb carcass and meat quality was evaluated. Two experiments were conducted in consecutive years with 60 crossbreed lambs each year. The animals were stratified by live weight (LW) and randomly assigned to the treatments: white clover grazing (WC); WC plus concentrate supplementation (WC + C); WC plus concentrate supplementation and quebracho and chestnut extract (WC + C + CT); Lotus uliginosus grazing (E-Tanin); E-Tanin plus concentrate supplementation (E-Tanin + C); E-Tanin plus concentrate supplementation plus quebracho and chestnut extract (E-Tanin + C + CT); with two repetitions each year. Pasture type affected loin weight, which was greater (P < 0.05) in lambs grazing WC than E-Tanin. Meat color redness (a*) was greater (P < 0.05) in supplemented treatments with C (with or without CT) than those exclusively grazing. Intramuscular fat content was not affected (P > 0.05) by the pasture, the supplementation, or the year. The proportion of dihomo-gamma-linolenic acid (C20:3-n6) was greater (P < 0.05) in lambs grazing E-Tanin compared to WC. Supplementation affected (P < 0.05) the saturated (SFA) and monounsaturated fatty acids (MUFA) proportions, and the omega 6:omega 3 ratio. Estimation of dry matter intake under grazing conditions would allow a better understanding of the effect of CT on carcass and meat quality. Resumen: Se evaluó el efecto de los taninos condensados (TC) en la pastura (Lotus uliginosus cv. E-Tanin) y/o extractos de quebracho y castaño en la calidad de la canal y carne de corderos. Se realizaron dos experimentos en años consecutivos con 60 corderos cruza cada año. Los animales fueron estratificados por peso vivo (PV) y asignados al azar a los tratamientos: pastoreo de trébol blanco (TB); pastoreo de TB más ración (TB + R); pastoreo de trébol blanco más ración y extracto de quebracho y castaño (TB + R + TC); pastoreo de Lotus uliginosus (E-Tanin); pastoreo de E-Tanin más ración (E-Tanin+R); pastoreo de E-Tanin más ración y extracto de quebracho y castaño (E-Tanin + R + TC), cada uno con dos repeticiones cada año. La pastura afectó el peso del bife, que fue mayor (P < 0,05) en los animales que pastorearon TB respecto a aquellos sobre E-Tanin. La intensidad de rojo (a*) del color de la carne fue mayor (P < 0,05) en los tratamientos suplementados con R (con y sin TC) respecto a aquellos exclusivamente pastoriles. El contenido de grasa intramuscular no fue afectado (P > 0,05) por el tipo de pastura, suplementación, o año. Los corderos que pastorearon E-Tanin presentaron una mayor (P < 0,05) proporción del ácido dihomo-gamma-linolénico (C20:3-n6) que aquellos sobre TB. La suplementación afectó (P < 0,05) las proporciones de ácidos grasos saturados (AGS) y monoinsaturados (AGM), y la relación omega 6:omega 3. Estimaciones del consumo en condiciones de pastoreo permitirían conocer mejor el efecto de los TC en la calidad de la canal y la carne.

The objective of this study was to evaluate the effects of the energy restriction of gestation of adult ewes from day 45 to day 115 on lamb live performance parameters, carcass and meat traits. In experiment I, dietary energy was restricted at 70% of the metabolizable energy (ME) requirements, after which ewes were re-fed ad libitum until lambing. In experiment II, dietary energy was restricted at 60% of the ME requirements, and ewes were re-fed to ME requirements until lambing. All ewes grazed together from the end of the restriction periods to weaning. Lambs were weaned and lot fed until slaughter. Feed intake, weight gain and feed efficiency were recorded, and body fat thickness and ribeye area (REA) were measured in the longissimus thoracis muscle. After slaughter, carcass weight and yield, fat depth, carcass and leg length, and frenched rack and leg weights and yields were determined. Muscle fiber type composition, Warner-Bratzler shear force, pH and color were determined in the longissimus lumborum muscle. In experiment I, energy restriction followed by ad libitum feeding affected lamb birth weight (P0.05) were observed on later BW, REA, BF or carcass traits. Lambs born to non-restricted-fed ewes had higher (P<0.05) weight and yield of the frenched rack cut and their meat tended (P=0.11) to be tender compared with that of lambs from restricted ewes. The percentage of oxidative muscle fibers was lower for lambs born to non-restricted ewes (P<0.05); however, no effects of ewe treatment were observed on other muscle fiber types. For experiment II, energy restriction followed by ME requirements feeding, affected (P<0.01) pre-weaning live weight gain, weaning and final weights. Lambs from restricted ewes had higher (P<0.05) feed intake as % of leg weight and a trend to be less efficient (P=0.16) than lambs from unrestricted dams. Ribeye area and BF were not influenced by treatment. Treatment significantly affected slaughter weight, but had no effects on carcass yield and traits or on meat traits. The results obtained in both experiments indicate submitting ewes to energy restriction during gestation affects the performance of their progeny but the final outcome would depend on the ewe's re-feeding level during late gestation and the capacity of the offspring to compensate the in utero restriction after birth.
