Figure 1. The effect of treatment on labour of workers during piglets castration. CTRL: a control of castration without pain relief, as usually performed by the hosting farm; AZA-MEL: castration was carried out after two intramuscular injections, one of meloxicam, the other of azaperone; PROC-MEL: castration was carried out after an intramuscular injection of meloxicam and a subcutaneous injection of procaine hydrochloride and adrenaline tartrate. Different letters (a, b) mean significant differences (p < .001) between values.
Figure 2. Average body weight (kg) for each class of mortality during lactation of piglets in litters castrated after two intramuscular injections, one of meloxicam, the other of azaperone (AZA-MEL group). 0 (no piglet dead), 1 piglet dead, 2 piglets dead, and 3 or more piglets dead. p = .048.
Table 1. Labour, mortality and costs estimation related to the treatment group, expressed for each processed litter and for each male castrated piglet.
