3.1. Physiological variables
The least squares means (±SE) for plasmatic and haematological
stress indicators are shown in Table 1. Glucose levels were significantly
(P b 0.05) higher (16.3%) in EE lambs but NEFA levelswere significantly
(P b 0.05) higher (133%) in CO lambs. No significant differences
between treatments were detected for cortisol, lactate or CK. The N/L
ratio was significantly (P b 0.05) higher (42.1%) in CO lambs. No significant
differences were found between treatments for the other haematological
variables. The IRT values were similar in both treatments.
