Rearing early weaned piglets artificially for the purpose of increasing the efficiency of the sow is an attractive management concept. However, high death losses resulting from diarrhea in artificially reared piglets have dampered enthusiasm for early weaning. Enterotoxigenic Escherichia coli, transmissible gastroenteritis virus and rotavirus are the three main enteropathogens responsible for causing the diarrhea. The enteropathogens infect the small intestine, which produces a secretory or malabsorptive diarrhea. In nature, the nursing piglet is protected from the enteropathogens by antibody bathing his gut. The source of the antibody is the dam's colostrum and milk. It should be possible to protect artificially reared, early weaned piglets from enteropathogens by feeding them diets that contain antibodies to putative enteropathogens.

European foulbrood (EFB) is a bee larvae-specific infectious disease and the causative pathogen is Melissococcus plutonius. Broad-spectrum antibiotics have classically been used in many countries to control the pathogens; however, their use in apiaries was discontinued in several countries due to concerns regarding the health of bees and humans. Therefore, the development of alternative treatments for use in apiaries that are safe for bees and humans is essential.

(Matsumura) (Diptera: Drosophilidae) is a global invasive pest attacking soft-skinned fruit. The specialist larval parasitoid wasp, (Ihering), was recently approved in Europe and the United States for classical biological control releases against . Rearing methods are essential for supporting innundative releases but current methods using fresh fruit are costly and susceptible to variation in host quality.

Artificial rearing (AR) of lambs is nowadays a common practice in Mediterranean dairy sheep production systems to enhance the milk available for cheese or yoghurt manufacturing. The sufficient growth of lambs in an AR system is vital for the economic success of dairy sheep farms. However, AR is often associated with negative impacts on the performance and physiology of lambs.

Grapholita molesta (Busck) (Lepidoptera: Tortricidae) is a major pest of many fruit trees. The large-scale artificial propagation technology of the insect is the basis for the field application of the sterile insect technique and biological control products based on host mass reproduction. However, a low-cost diet with easily accessible materials remains lacking.

We present an artificial intelligence (AI)-enhanced monitoring framework designed to assist personnel in evaluating and maintaining animal welfare using a modular architecture. This framework integrates multiple deep learning models to automatically compute metrics relevant to assessing animal well-being. Using deep learning for AI-based vision adapted from industrial applications and human behavioral analysis, the framework includes modules for markerless animal identification and health status assessment (e.
