Twelve bulls were sorted into three groups of four animals each and assigned to three treatment hours: control (0), 4, or 6, using a complete randomized design (CRD). The results of the study show that there are no significant differences (p > 0.05) in slaughter weight, hot carcass weight (HCW), chilling loss, total edible and non-edible offal, fat thickness (FT), deboned meat yield (kg), meat to bone ratio, muscle distribution, and proportion of kidney, pelvic, and heart fat (KPH%) among the treatment groups. However, the hot carcass-based dressing percentage was significantly lowered (p < 0.05) in bulls that work 4 or 6 hours a day. Meat yield was strongly correlated with HCW (r = 0.74) and FT (r = 0.73). Therefore, the number of hours the bull spent on draught work did not negatively impact meat yield or quality. Consequently, the research suggests that utilizing Hararghe highland bulls for draught service, four or six hours a day is viable for dual advantages: crop cultivation and marketable carcass.展开更多

It is becoming fashionable in markets inside and outside China with its fresh, pure and refreshing taste. Drinking draught beer has become the vogue these days. "Huasi" draught beer is a kind of fresh beer produced by the Beijing Huasi Lubao Beer Co. Ltd. through years of painstaking research with the characteristics of pure and refreshing taste, high nutrition and a genuine hops flavour. Using selected materials of high quality,展开更多

The results showed that the water potential threshold for inducing embolism in three species was -0 1-0 3MPa, and the embolism reached its maximum value at the water potential of -2 5-3 5MPa. The xylem embolism vulnerability of three species was in the order of Hippophae> Ulmus> Corylus. The refilling of embolized xylem could occur while the water potential is below zero in all the species. In Hippophae, fully restoring occurred after thirty minutes under the water potential of -0 5MPa and -1 0MPa, but for Ulmus and Corylus, the restoration could reach about 90% in thirty minutes under the water potential of -0 60MPa and -0 34MPa, respectively. Ulmus could restore fully through one night (12hours) under the water potential of -0 59MPa. The refilling capacity of three species was Hippophae> Ulmus> Corylus . The xylem of the three draught-tolerant species is not only very vulnerable to embolization or very sensible to water stress but also capable of refilling its embolized xylem in a short period of time. Vulnerable and drought-tolerant species had significant xylem embolism in higher water potential, which decreased the hydraulic conductivity so that limited water loss. Drought-tolerant species had more ability to refill its embolized xylem in a short period of time. These were the ways through which trees resist and tolerate drought or water stress.展开更多
