“…Overviews of primate repertoires broadly support expected differences across contexts that putatively correspond to different levels of motivation, but there are exceptions that indicate additional influences of external referents and social contexts on call structure Gouzoules and Gouzoules 2000;Hauser 1993;Schrader and Todt 1993). More convincing support comes from empirical observations of changes in call structure in a variety of species in which researchers experimentally manipulated affective states (Fichtel et al 2001;Watts et al 1999;Weary et al 1998). Results reveal a more complex relationship than simply changes in absolute frequency and tonality.…”

Researchers studying nonhuman primate vocal repertoires suggest that convergent environmental, social, and motivational factors account for intra-and interspecific vocal variation. We provide a detailed overview of the vocal repertoire of white-faced capuchins, including acoustic analyses and contextual information of vocal production and vocal usage by different age-sex classes in social interactions. The repertoire is a mixture of graded and discrete vocalizations. In addition, there is general support for structural variation in vocalizations with changes in arousal level. We also identified several combined vocalizations, which might represent variable underlying motivations. Lastly, by including data on the social contexts and production of vocalizations by different age-sex classes, we provide preliminary information about the function of vocalizations in social interactions for individuals of different rank, age, and sex. Future studies are necessary to explore the function of combined vocalizations and how the social function of vocalizations relate to their Int J Primatol (

“…In addition, Puppe et al (2005) showed that the entropy of the high-frequency vocalisation was lower during castration compared with the pre-surgical period. Similarly, Watts and Stookey (1999) observed that, compared with controls, calves subjected to hot-iron branding showed a greater frequency range in the fundamental or lowest harmonic of the audiospectrogram of their vocalisations, a higher maximum frequency and a higher peak sound level. However, many animals also vocalise during non-painful handling.…”

One important objective for animal welfare is to maintain animals free from pain, injury or disease. Therefore, detecting and evaluating the intensity of animal pain is crucial. As animals cannot directly communicate their feelings, it is necessary to identify sensitive and specific indicators that can be easily used. The aim of the present paper is to review relevant indicators to assess pain in several farm species. The term pain is used for mammals, birds and fish, even though the abilities of the various species to experience the emotional component of pain may be different. Numerous behavioural changes are associated with pain and many of them could be used on farms to assess the degree of pain being experienced by an animal. Pain, as a stressor, is associated with variations in the hypothalamic-pituitary-adrenal axis as well as in the sympathetic and immune systems that can be used to identify the presence of pain rapidly after it started. However, most of these measures need sophisticated equipment for their assessment. Therefore, they are mainly adapted to experimental situations. Injuries and other lesional indicators give information on the sources of pain and are convenient to use in all types of situations. Histopathological analyses can identify sources of pain in experimental studies. When pronounced and/or long lasting, the pain-induced behavioural and physiological changes can decrease production performance. Some indicators are very specific and sensitive to pain, whereas others are more generally related to stressful situations. The latter can be used to indicate that animals are suffering from something, which may be pain. Overall, this literature review shows that several indicators exist to assess pain in mammals, a few in birds and very few in fish. Even if in some cases, a single indicator, usually a behavioural indicator, may be sufficient to detect pain, combining various types of indicators increases sensitivity and specificity of pain assessment. Research is needed to build and validate new indicators and to develop systems of pain assessment adapted to each type of situation and each species.

“…Collection of some of the physiological measurements require the animal to be restrained, compromising the ability to interpret changes as painful as opposed to stressful. Other pain assessment systems have been developed in response to this, and they rely on monitoring short-term behaviors such as vocalizations [96], escape attempts [97], lameness [94], or posture changes [57,98] where animals try to adopt a position that limits the pain experienced. Many of these indicators are not pain specific and can be seen in response to other affective states such as fear or stress, or even positive states such as joy.…”

Why Pain Is Still a Welfare Issue for Farm Animals, and How Facial Expression Could Be the Answer

Pain is a sensory and emotional experience that significantly affects animal welfare and has negative impacts on the economics of farming. Pain is often associated with common production diseases such as lameness and mastitis, as well as introduced to the animal through routine husbandry practices such as castration and tail docking. Farm animals are prey species which tend not to overtly express pain or weakness, making recognizing and evaluating pain incredibly difficult. Current methods of pain assessment do not provide information on what the animal is experiencing at that moment in time, only that its experience is having a long term negative impact on its behavior and biological functioning. Measures that provide reliable information about the animals' affective state in that moment are urgently required; facial expression as a pain assessment tool has this ability. Automation of the detection and analysis of facial expression is currently in development, providing further incentive to use these methods in animal welfare assessment.
