Ethical and commercial issues are associated with animal welfare in pig farming, in that sense, the objective of this work was to evaluate physiological and blood parameters in addition to weight gain in pigs raised with and without sunlight and environmental enrichment (EE), as well as to correlate physiological and environmental parameters as welfare indicators. Twenty-four pigs distributed in a randomized block design with a 2 × 2 factorial arrangement were used. Blocks were represented by shifts (morning and afternoon), and factors by the presence or absence of EE and sunlight. Blood and environmental parameters of thermal comfort, in addition to weight gain, were registered. Physiological parameters showed to be shift dependent (p < 0.05), with the afternoon shift being superior when compared to the morning shift, thus indicating climate influence. Weight gain showed significant interactions (p < 0.05) in the presence and absence of sunlight and EE in the stalls. Temperature correlated positively with the physiological parameters. Moisture showed negative correlations with physiological parameters. The packed cell volume was lower (p < 0.05) in the presence of EE. The EE provides physiological well-being and weight gain for pigs in the nursery stage, especially when sunlight was absent in the stalls.

“…Differences in cortisol levels between the pigs submitted to the pre-slaughter and stunning stress and those ones that were not exposed to this condition was reported, suggesting that cortisol level might be also used as welfare status indicator [ 24 ]. Other authors [ 25 ] evaluated the Phosphocreatine Kinase (PCK), the Lactate Dehydrogenase enzymes and the glucose in blood samples, in addition to the salivary cortisol levels, normal heart rate, and heart rate during the pre-slaughter handling of pigs, and found that the pre-slaughter resting period significantly influenced the concentrations of lactate in the blood and the salivary cortisol levels. However, during the transportation, the heart rate was greater than elsewhere evaluated.…”

Simple SummaryThis research aimed to analyze the possibility of assessing piglets’ welfare using the records of their vocalization. The trial was done in a pig commercial farm, and we recorded the vocal signals from piglets in several stressful exposure situations. Data mining techniques were applied to the processed signals in order to obtain a stress classification using the recorded data. We found that, using the piglets’ vocalization, it was possible to identify the most frequent stressful conditions at the farrowing phase, namely: pain, cold and hunger.AbstractAssessing pigs’ welfare is one of the most challenging subjects in intensive pig farming. Animal vocalization analysis is a noninvasive procedure and may be used as a tool for assessing animal welfare status. The objective of this research was to identify stress conditions in piglets reared in farrowing pens through their vocalization. Vocal signals were collected from 40 animals under the following situations: normal (baseline), feeling cold, in pain, and feeling hunger. A unidirectional microphone positioned about 15 cm from the animals’ mouth was used for recording the acoustic signals. The microphone was connected to a digital recorder, where the signals were digitized at the 44,100 Hz frequency. The collected sounds were edited and analyzed. The J48 decision tree algorithm available at the Weka® data mining software was used for stress classification. It was possible to categorize diverse conditions from the piglets’ vocalization during the farrowing phase (pain, cold and hunger), with an accuracy rate of 81.12%. Results indicated that vocalization might be an effective welfare indicator, and it could be applied for assessing distress from pain, cold and hunger in farrowing piglets.

“…Em razão das condições de estresse pré-abate, há também um aumento da concentração do cortisol plasmático em suínos (LUDTKE et al, 2012), o qual pode ser mensurado na saliva ou soro através de reações imunoenzimáticas [69] ou por meio de técnicas de radioimunoensaio (RIA) (SANTANA et al, 2009;DALLA COSTA et al, 2009;(LUDTKE et al, 2012),). Essa análise é utilizada como marcador de estresse e da qualidade cárnea, já que há uma correlação entre a acidez da carne a altos níveis de cortisol e adrenalina (FOURY et al, 2005).…”
