Risk factors and detection of lameness using infrared thermography in dairy cows- a review

Novotna I., Langova L., Havlicek Z.

Published in 2019

Lameness in dairy cows is a worldwide problem, usually a consequence of hoof diseases. Hoof problems have a negative impact on animal health and welfare as well as the economy of the farm. Prevention and early diagnosis of lameness should prevent the development of the disease and consequent high costs of animal treatment. In this review, the most common causes of both infectious and noninfectious lesions are described. Susceptibility to lesions is primarily influenced by the quality of the horn. The quality of the horn is influenced by internal and external conditions such as hygiene, nutrition, hormonal changes during calving and lactation, the animal's age or genetic predisposition. The next part of this review summarizes the basic principles and possibilities of using infrared thermography in the early detection of lameness in dairy cows.

Welfare Quality® assessment protocol for cattle

Published in 2009

Welfare Quality® combines analysis of consumer perceptions and attitudes with current knowledge from animal welfare science. This has led to the identification of 12 criteria that must be properly taken into account by evaluation systems. To address these issues, it has been decided to focus on those indicators classified as animal-based, which address aspects of the immediate welfare status of animals, such as their behaviour, fear, health or physical condition. These animal-based measures include the effects of variations in farm system management (role of the farmer) as well as particular system-animal interactions. It is however clear that resource-based and management-based measures can also contribute to a welfare assessment if they are closely correlated with animal-based measures. In addition, resource- and management-based measures can be used to identify animal welfare risks and to identify the causes of poor welfare so that improvement strategies can be implemented.
This protocol describes the procedures and requirements for the assessment of the welfare of cattle and is limited to the main categories of production animals, i.e. feeder cattle, dairy cows and veal calves. The document first outlines the on-farm collection of measurement data on feeder cattle, followed by the procedures for calculating scores. The next section describes the collection of data at the abattoir to assess the welfare of feeder cattle at the time of slaughter. Next, the procedure for on-farm collection of measurement data on dairy cows and the calculation of scores for overall farm welfare assessment is described, followed by the protocols for on-farm collection of the same data from calves, along with a description of data collection protocols for measurements taken at the abattoir but relevant to farm welfare. These last two sections complement each other and are used together to calculate on-farm welfare scores for veal calves.

Douleurs animales. 2. Evaluation et traitement de la douleur chez les ruminants

The establishment of efficient and simple tools to detect pain and assess its intensity would make it possible to meet the needs of professionals (farmers and producers, veterinarians, researchers, etc.), to answer questions raised by public opinion and debate on animal pain and to meet the requirements of the regulations on the use of animals for scientific purposes (cf. Coetzee 2013, bibliographical review). Recent studies have already enabled the identification of behavioural, zootechnical and physiological indicators for the presence and even the intensity of pain (cf. review of the literature by Prunier et al 2013). However, no integrated approach involving the simultaneous use of all these indicators has been developed to date. Moreover, some indicators cannot be used in current practice, and the sensitivity (Se) and specificity (Sp) of the various potential indicators are not always optimal. One route is to combine the indicators in order to increase their informational value. Through this overview, we wish to show i) that evaluation of type and level of pain is essential for optimal pain management and ii) that an evaluation based on a multiparametric approach is best suited to such an objective.

La Conscience des Animaux

Are animals conscious beings?  How do they perceive their own worlds? These questions are being debated in the scientific community for both academic and practical reasons. Accordingly, on 7 July 2012, a group of leading scientists in England headed by Philip Low felt it necessary to publish The Cambridge Declaration on Consciousness. This manifesto states that "a convergence of evidence indicates that non-human animals have the neuro-anatomical, neurochemical and neurophysiological substrates of conscious states as well as the ability to express intentional behaviour...". It calls for further research to learn more about this capacity in animals. In 2015, INRA carried out a multidisciplinary scientific expertise in order to provide a critical review of the literature on animal consciousness. This work was executed at the request of the European Food Safety Authority (request EFSA-Q-2015-00390, contract no. EFSA/Inra/2015/01).

This study is an overview based on the report from INRA's collective scientific expertise (Le Neindre et al., 2017). It is divided into six chapters:
––the social, ethical and legal context for the expertise (chapter 1)
––consciousness in the animal kingdom: historical perspectives, epistemology and definitions (chap. 2)
––overview of current knowledge on human consciousness, with a discussion of the main current innovative concepts given their usefulness for our understanding of the available data on animals (Chapter 3)
––behavioural and neurobiological components in animals that allow us to talk about more or less elaborate content of consciousness. This chapter constitutes the core of the expertise (chap. 4).
––the positive consequences of taking consciousness into account on our understanding of welfare, suffering and pain (chap. 5)
––the importance of consciousness in the adaptive capacities of animals, especially in their phylogenetic components (Chapter 6)
The book concludes with proposals for future avenues of research resulting from the deliberations of various scientific bodies.
