Abscisic Acid-Mediated Drought Stress
Drought is one of the major constraints to rain-fed agricultural production, especially under climate change conditions. Plants evolved an array of adaptive strategies that perceive stress stimuli and respond to these stress signals through specific mechanisms. Abscisic acid (ABA) is a premier signal for plants to respond to drought and plays a critical role in plant growth and development.

Method of Pest Control in Insects
Modern agriculture and public health management both depend heavily on insect pest control. It includes a range of tactics and strategies meant to control and lessen the negative effects that insect pests have on human, animal, and agricultural populations.Chemical pesticides are a primary method of controlling insect pests. These chemicals are intended to target particular pests and disturb their life cycles or kill them. However, a heavy dependence on pesticides can result in damage to non-target creatures, environmental contamination, and pesticide resistance. Consequently, integrated pest management (IPM) has grown in popularity. IPM incorporates several tactics, such as mechanical measures (traps and barriers), cultural practices (rotation crops or modifying planting timings), and biological management (using natural predators or parasites to reduce pest populations). This minimizes the need for chemical treatments. Sustainable and environmentally friendly pest management techniques have become more popular recently, placing a focus on the use of biopesticides (naturally occurring organisms or their derivatives) and genetically modifying crops to ward off pests. Furthermore, developments in monitoring technology like remote sensing and data analytics assist farmers in making wise choices about pest control. Finally, insect pest management is a complex enterprise that has evolved to strike a balance between the need for pest mitigation and worries about the environment and human health, eventually maintaining food security and the health of ecosystems.

Grapevine Cane Extracts
Grapevine canes are viticulture waste that is usually discarded without any further use. However, recent studies have shown that they contain significant concentrations of healthpromoting compounds, such as stilbenes, secondary metabolites of plants produced as a response to biotic and abiotic stress from fungal disease or dryness. Stilbenes have been associated with antioxidant, anti‐inflammatory, and anti‐microbial properties and they have been tested as potential treatments of cardiovascular and neurological diseases, and even cancer, with promising results. Stilbenes have been described in the different genus of the Vitaceae family, the Vitis genera being one of the most widely studied due to its important applications and economic impact around the world. This entry presents an in‐depth study of the composition and concentration of stilbenes in grapevine canes. The results show that the concentration of stilbenes in grapevine canes is highly influenced by the Vitis genus and cultivar aspects (growing conditions, ultraviolet radiation, fungal attack, etc.). Different methods for extracting stilbenes from grapevine canes have been reviewed, and the extraction conditions have also been studied, underlining the advantages and disadvantages of each technique. After the stilbenes were extracted, they were analyzed to determine the stilbene composition and concentration. Analytical techniques have been employed with this aim, in most cases using liquid chromatography, coupled with others such as mass spectrometry and/or nuclear magnetic resonance to achieve the individual quantification. Finally, stilbene extracts may be applied in multiple fields based on their properties. The five most relevant are preservative, antifungal, insecticide, and biostimulant applications. The current state‐of‐the‐art of the above applications and their prospects are discussed.

Antioxidant
The primary objectives of modern agriculture includes the environmental sustainability, low production costs, improved plants’ resilience to various biotic and abiotic stresses, and high sowing seed value. Delayed and inconsistent field emergence poses a significant threat in the production of agri-crop, especially during drought and adverse weather conditions. To open new routes of nutrients’ acquisition and revolutionizing the adapted solutions, stewardship planswill be needed to address these questions.One approach is the identification of plant based bioactive molecules capable of altering plant metabolism pathways which may enhance plant performance in a brief period of time and in a cost-effective manner.A biostimulant is a plant material, microorganism, or any other organic compound that not only improves the nutritional aspects, vitality, general health but also enhances the seed qualityperformance.

Tetranychus urticae in Northern Africa
In North Africa, Tetranychus urticae Koch, 1836 represents one of the most destructive generalists among mite herbivores. Unfortunately, it is a source of important annual casualties in crop production. It is a phytophagous mite that can feed on hundreds of host plants and produces significant damage. The control of Tetranychus urticae in North Africa has been principally based on acaricide sprays. However, new alternative methods have shown effective results, such as artificial ultraviolet-B, natural enemies, and the introduction of new genetic methods.

Application of Campylobacter jejuni Phages
Campylobacter jejuni is a zoonotic bacterial pathogen found in abundance, e.g., in raw poultry. C. jejuni is part of the avian gut microbiome, causing no harm to birds. When birds are slaughtered, the bacterium is released from the intestines and contaminates the meat. Cross-contaminated foods processed in parallel to the meat cause diarrhea in humans and in rare cases may cause post-infectious complications like arthritis and paralysis of peripheral nerves. Illnesses caused by C. jejuni have been on the rise in both developed and developing countries. At the same time, C. jejuni has acquired resistance to important antibiotics, which further complicates therapeutic approaches. To decrease the Campylobacter load on chicken carcasses, chemical or thermal treatment can be used. However, this may change the taste or affect the appearance of chicken meat.

Quantify Heat Stress Response in Farm Animals
Non-invasive methods of detecting heat stress magnitude for livestock is gaining momentum in the context of global climate change. The concept of a non-invasive approach to assess heat stress primarily looks into behavioral and physiological responses which can be monitored without any human interference or additional stress on the animal. Bioclimatic thermal indices can be considered as the least invasive approach to assess and/or predict the level of heat stress in livestock. Assessing these responses can prove beneficial to quantifying heat stress and thereby enforcing suitable amelioration and mitigation strategies. There are a number of approaches to quantify heat stress, which in the current scenario with increasing animal welfare concern, can be considered as invasive and non-invasive approaches.

Conservation in South African Indigenous Goat Ecotypes
Goats were amongst the first livestock to be domesticated more than 10,000 years ago for their meat, milk, skin, and fiber. They were introduced to Southern Africa by migrating nations from Central Africa to the south. Due to local adaptation to the different agro-ecological zones and selection, indigenous goats are identified as ecotypes within the indigenous veld goat breed. Their ability to thrive in a resource-limited production system and in challenging environmental conditions makes them valuable animal resources for small-scale and emerging farmers. They play important roles in household agriculture and cultural activities as well as in poverty alleviation.

Inflammatory Bowel Diseases in Dogs
Canine inflammatory bowel diseases (IBD) are of increasing interest in veterinary medicine. They refer to complex and debilitating conditions of dogs’ gastrointestinal tract. Although little evidence for causal inferences is currently available, it is believed that IBD pathophysiology entails intricate interactions between environmental factors, the intestinal immune system, and the microbial communities that colonize the gut. To better understand the mechanisms underlying these disorders, leveraging factors associated with the development of these diseases is imperative. Of these factors, emerging evidence supports the role of dietary patterns as key players influencing the composition and function of gut microbes, with subsequent effects on health and disease.

‘Cow Signs’ in Assessing the Quality of Nutrition
Cow signs are behavioral, physiological, and management parameters that can be observed and measured. Cow signs can be used as a field approach to evaluate the composition of the ration, the quality of rumen fermentation, the quality of digestion, and the general herd health of cattle of interest. This research of cow signs associated with nutrition provides farm advisors, consultants, nutritionists, practitioners, and dairy farmers with an additional toolkit that can be used to improve the assessment of the quality of dairy cattle nutrition. ‘Cow signs’ are not to be used alone as a sole tool for assessment of the quality or nutrition of dairy cows. Some of the ‘cow signs’ are incorporated in precision technologies on many dairy farms and are extensively used in the assessment of dairy cow welfare, health, and nutrition.

Role of Riboflavin in Poultry Nutrition
Riboflavin, an essential B-vitamin, plays a crucial role in poultry metabolism, impacting energy production, growth, and immune regulation. Its role in redox reactions and energy metabolism is vital for optimal growth and development. Riboflavin is essential for adenosine triphosphate (ATP) production and the conversion of tryptophan into niacin. Deficiency can lead to skeletal deformities, impaired growth, and compromised immune function. Dietary riboflavin supplementation is necessary due to variable bioavailability in plant-derived sources. The vitamin is absorbed through specialized transport proteins, and its cellular uptake is facilitated by specific receptors. Riboflavin’s role in protein synthesis and its antioxidant properties influence poultry growth and defense against oxidative stress. Its impact on reproductive performance, hatchability, and overall poultry health underscores its significance in poultry nutrition.
