Antimicrobial peptides (AMPs) are the arsenals of the innate host defense system, exhibiting evolutionarily conserved characteristics that are present in practically all forms of life. Recent years have witnessed the emergence of antibiotic-resistant bacteria compounded with a slow discovery rate for new antibiotics that have necessitated scientific efforts to search for alternatives to antibiotics. Research on the identification of AMPs has generated very encouraging evidence that they curb infectious pathologies and are also useful as novel biologics to function as immunotherapeutic agents. Being innate, they exhibit the least cytotoxicity to the host and exerts a wide spectrum of biological activity including low resistance among microbes and increased wound healing actions. Notably, in veterinary science, the constant practice of massive doses of antibiotics with inappropriate withdrawal programs led to a high risk of livestock-associated antimicrobial resistance. Therefore, the world faces tremendous pressure for designing and devising strategies to mitigate the use of antibiotics in animals and keep it safe for posterity. In this review, we illustrate the diversity of farm animal-specific AMPs, and their biochemical foundations, mode of action, and prospective application in clinics. Subsequently, we present the data for their systematic classification under the major and minor groups, antipathogenic action, and allied bioactivities in the host. Finally, we address the limitations of their clinical implementation and envision areas for further advancement.

Livestock industry is one of the important pillars for country economy. Sperm sexing has the potential of significantly improving the quality and quantity of production in the livestock industries. Over years several attempts, involving several different parameters of sperm cells, have been made to develop an efficient sperm sorting procedure. Till date, the only commercially available method for bovine sperm is flow cytometry. The disadvantages associated with this approach, however, points towards the need for developing a more non-invasive and cost efficient approach for separation of X and Y chromosome bearing spermatozoa. In this review paper, we attempt to highlight all the previously developed approaches, as well as other emerging immunological and proteomics based methods that might have the potential of being developed as a promising breakthrough approach for semen sexing. Furthermore, we discuss the advantages and applications of semen sexing in India and around the world.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
