La césarienne est un acte fréquemment réalisé par les médecins vétérinaires belges, les procédures et les techniques peuvent varier fortement en fonction du praticien ou du nombre réalisé par an. Un sondage a été réalisé pour nous éclairer sur la situation actuelle quant aux techniques et matériaux utilisés par des médecins vétérinaires pratiquant en Belgique et en France. Dans un deuxième temps, une étude de terrain a été programmée pour analyser l’évolution de la cicatrisation des plaies cutanées suite à des césariennes sur des vaches de race Blanc-Bleu Belge dans différents élevages en Wallonie, réalisées par différents vétérinaires. Des différences significatives sont observées entre les types de fils et de sutures plus particulièrement sur l'inflammation, le suintement, la déhiscence, l'infection et la nécrose au niveau de la plaie. Caesarean section is a procedure frequently performed by Belgian veterinarians, the procedures and techniques can vary greatly depending on the practitioner or the number performed per year. A survey was carried out to shed light on the current situation regarding the techniques and materials used by veterinary doctors practizing in Belgium and in France. In a second step, a field study was programmed to analyze the evolution of the healing of skin wounds following caesarean sections on cows of the Belgian White-Blue breed in different farms in Wallonia, carried out by different veterinarians. Significant differences are observed between the type of suture material and the suture pattern, more particularly on inflammation, oozing, dehiscence, infection and necrosis at the wound.

"This book is a valuable and innovative piece of scholarship. It advances the broadening field of studies devoted to understanding how animal breeding has evolved after the advent of the science of genetics. Animal breeding is an ancient human occupation, but it has undergone profound changes which have stressed and modified old ways over the past 120 years. This book looks at the interface between science and practice in the breeding of farm animals with a special focus on Dutch livestock breeding. It argues that it is too simplistic to see the infiltration of genetics into practice as merely modernization."--

Mycotoxins represent a significant issue for the feed industry and the safety of the feed supply chain, with an impact on human health, animal health and production, economies, and international trade. The globalization of the trade in agricultural commodities and the lack of legislative harmonization have contributed significantly to the discussion about the awareness of mycotoxins entering the feed/food supply chain. The feed industry is a sustainable outlet for food processing industries, converting byproducts into high-quality animal feed. Mycotoxin occurrence in food byproducts from different technological processes is a worldwide topic of interest for the feed industry, aiming to increase the marketability and acceptance of these products as feed ingredients and include them safely in the feed supply chain. Since mycotoxin contamination cannot be completely prevented pre- or post-harvest, the modern feed industry needs new tools for monitoring and managing the risk of mycotoxins and strategies to prevent and reduce mycotoxins in compound feed manufacturing. The aim of this Special Issue book was to bring together a collection of valuable articles with innovative ideas for a sustainable and competitive feed industry.

Comfort during resting, half-closed eyes when feeding on highly palatable feed, or vigorous tail wagging when being brushed are some of the positive indicators that can be used to evaluate the quality of the environment in which domestic animals live. This has been a radical shift from the past as, until now, the welfare assessment on farms has meant assessing negative indicators, namely the number of lame animals, presence of lesions, or frequency of agonistic behaviours. However, the latest research confirms that the absence of a problem or of suffering does not necessarily imply that the animals are experiencing a good life and that their level of welfare is high. To guarantee high welfare standards, animals should experience positive conditions that allow them to live a “life worth living”, and positive indicators are needed to identify these conditions. This Special Issue focuses on the development and validation of indicators of positive welfare or on the refinement of the existing ones, as well as on the identification of suitable living conditions for providing positive welfare to farmed and companion animals.

From birth to first calving, the replacement heifer undergoes tremendous changes anatomically as well as in feeding and management practices. The calf changes from being a pseudo-monogastric to a full ruminant within a period of two months. During the same period, the calf is fed colostrum, milk, or milk replacer, and starter with or without hay. Notably, the lifetime milk production and health of a dairy cow is highly dependent on early life nutrition and management of the calf and, subsequently, the heifer. Hence, animal scientists continue to investigate critical areas such as colostrum feeding, the level of liquid feeding, gut microbial succession, energy and protein levels, housing, health management, and their interactions with the animal in an effort to help dairy producers raise successful and sustainable dairy enterprises.

Ruminants contribute significantly to human food security. However, the production of ruminants contributes to greenhouse gas (GHG) emissions that are responsible for climate change. GHGs such as methane, carbon dioxide, and nitrous oxide are produced from different processes of ruminant production. Ruminant enteric methane is a substantial component of methane produced by agriculture. This book presents novel and established methods in quantifying and reducing enteric methane emission from ruminants in different production systems. The book covers different types of ruminants including cattle, sheep, and goats. The chapters are contributed by scientists and authors from different parts of the world, demonstrating the importance of this problem and the universal drive for immediate and sustainable solutions. Although, biologically speaking, the production of enteric methane cannot be reduced to zero, high emissions are an indicator of inefficient digestion of feed in the rumen and low utilisation of feed energy. By presenting research that could lead to robust and yet practical quantification methods and mitigation strategies, this book not only contributes to the discourse and new knowledge on the magnitude of the problem but also brings forward potential solutions in different livestock production systems.

Food safety is a major problem around the world, both with regard to human suffering and with respect to economic costs. Scientific advances have increased our knowledge surrounding the nutritional characteristics of foods and their effects on health. This means that a large proportion of consumers are much more conscious with respect to what they eat and their demands for quality food. Food quality is a complex term that includes, in addition to safety, other intrinsic characteristics, such as appearance, color, texture and flavor, and also extrinsic characteristics, such as perception or involvement.
