“…On the other hand, evidence suggests that low amplitude, low-frequency "purring" of domestic cats and other mammals may be indicators of positive affect (Kiley-Worthington, 1984;Fisher and Mathews, 2001;Peters, 2002). Recently, Pond et al (2010) demonstrated spectral differences between positive and negative quality vocalizations in the domestic horse using hidden Markov models. These studies show promise for the eventual detection and differentiation of affective states in animal vocalizations, but the clear distinction between changes in affect intensity and affect quality remains elusive, and no consistent acoustic pattern that distinguishes positive and negative affect has emerged.…”

“…Examples include an ultrasonic vocalization in rats produced during purported positive affective states such as during play and non-aggressive physical contact (Panksepp and Burgdorf, 2003), and antecedents of human laughter found in great apes (Davila Ross et al, 2009, 2010. In addition, Pond et al (2010) differentiated horse vocalizations produced in positive (feeding) and negative (social separation) contexts. Investigations that attempt to differentiate between positive and negative affect in animal vocalizations are of particular importance because analysis of vocalizations has been offered as a tool to measure the well-being of captive animals (e.g., Pond et al, 2010;Boissy et al, 2007;Schön et al, 2004;Manteuffel et al, 2004).…”

However, this approach can be useful only if vocalizations reflect the quality of affect (i.e., positive versus negative affect), in addition to the intensity of affect (i.e., the degree of arousal independent of affect quality).…”

As in other mammals, there is evidence that the African elephant voice reflects affect intensity, but it is less clear if positive and negative affective states are differentially reflected in the voice. An acoustic comparison was made between African elephant "rumble" vocalizations produced in negative social contexts (dominance interactions), neutral social contexts (minimal social activity), and positive social contexts (affiliative interactions) by four adult females housed at Disney's Animal Kingdom®. Rumbles produced in the negative social context exhibited higher and more variable fundamental frequencies (F(0)) and amplitudes, longer durations, increased voice roughness, and higher first formant locations (F1), compared to the neutral social context. Rumbles produced in the positive social context exhibited similar shifts in most variables (F(0 )variation, amplitude, amplitude variation, duration, and F1), but the magnitude of response was generally less than that observed in the negative context. Voice roughness and F(0) observed in the positive social context remained similar to that observed in the neutral context. These results are most consistent with the vocal expression of affect intensity, in which the negative social context elicited higher intensity levels than the positive context, but differential vocal expression of positive and negative affect cannot be ruled out.

Summary Veterinary surgeons are required to assess an animal's welfare in a range of different circumstances in the course of their daily work. These assessments may relate to the long‐term welfare of an individual animal under their care, or the current welfare of a population of animals that are unfamiliar to them as individuals. The welfare assessment made may subsequently have implications for the treatment that an animal receives or for the decision of whether or not an animal should remain in its current home. Yet welfare assessment is not straightforward. Here we review the challenges that welfare assessment presents and review the tools currently available to meet them. Lastly, we look towards the future of equine welfare assessment, with examples of current research to develop tools and optimise welfare assessment.

“…Among various vocalization types especially loud calls represent signals potentially encoding inter-species relationships in wild members and possibly among domestic breeds as well (Policht et al, 2011).The most pronounced loud call of horses is the whinny. This signal contains information about behavioural context, individual identity, social status, including body size (Kim et al, 2010;Lemasson et al, 2009;Pond et al, 2010;Proops et al, 2009), and therefore represents an ideal model signal to test this question.…”

Loud acoustic signals of mammals may contain information about their progenitors. There is a question whether such phenomenon is possible to expect in domestic animal breeds as well, since the time of breed establishment has been a rather long one. Therefore we tested whether a significant morphological distinction of a newly established horse breed and its important founding contributor differed in their vocalization. We analyzed 304 whinnies of 35 individual horses (197 whinnies of 23 individuals belonging to Czech Warmblood and 107 calls of 12 Thoroughbreds). Despite of the fact that the two breeds differed significantly in most of their morphological measurements (height at withers, thoracic perimeter, cannon bone perimeter, and body weight), they did not differ in any of the measured acoustic parameters (both frequency and temporal ones). Our results indicate that morphological distinction of Thoroughbred and Czech Warmblood was not accompanied by distinct vocalization.
