Contenido :  ABSTRACT. Aims: Comparing different winter legume species by plant traits that determine their contributions to ecosystems as service crops. Since root biomass determines soil organic matter formation and biological nitrogen fixation (BNF) increases soil organic nitrogen stock, those plant traits are more suitable than shoot biomass to select service crops. Methods: We evaluated shoot and root biomass and BNF (using 15N natural abundance method) of 10 winter legume service crop species under field conditions, in two consecutive years. Results: The legumes significantly varied in shoot (3.4 to 9.1 Mg ha?1 year?1) and root biomass (0.8 to 1.3 Mg ha?1 year?1) and in the proportion and the amount of biologically fixed nitrogen (36?61% and 43?121 kg of N ha?1, respectively). Whereas shoot biomass varied between years, root and BNF were rather constant determining a low correlation between the variables. Among the evaluated species, Trifolium pratense and T. alexandrinum were the top-ranked species for the evaluated conditions, showing the largest amount of root biomass (~ 1.3 Mg ha?1 year?1) and BNF (~ 112 kg of N ha?1 year?1). Conclusions: Selecting service crops species aimed to increase soil organic matter based only on shoot biomass may be insufficient. As a consequence, we highlight the importance of performing breeding programs aimed to increase, in addition to crop yield or shoot biomass production, other plant traits such as root biomass or biological nitrogen fixation th... Presentar Todo

Contenido :  Abstract: Sixty Hereford (H) and Braford (B) steers were assigned to two diets: D1) native pasture plus corn grain (1 % of live weight) (H n=15, B n=15); and D2) high quality pasture (H n=15, B n=15) for finishing purposes. Temperament was individually assessed and monitored during the experiment. All animals were slaughtered the same day in two groups (50 % of animals from D1 and 50 % from D2 in each group) after staying 15 and 3 hours in lairage pens, respectively. Different physiological indicators were used to assess stress after transport, lairage and immediately preslaughter. Carcass quality was determined through the incidence of bruising and final pH. Calmer animals had higher average daily gains (ADG) with no differences between diets. Transport was not a psychological stressful stage but animals were physically affected. The group that remained 3 hours in lairage pens showed a higher frequency of negative behaviour. These stressed animals did not have enough time to cope with the environment, with the consequent deleterious effects on final pH. The long lairage group had a higher metabolic response but these animals could rest and recover, and reached adequate final pH values. Braford steers were more excitable during the finishing period and also during lairage. Regardless of breed, temperament appears to be a valid tool for increasing productivity and decreasing the physiological stress response during all preslaughter stages. Further research should be carried o... Presentar Todo
