This second volume includes 31 scientific articles, in the text of individual chapters in this Frontiers Research Topic. The editors are grateful to all 197 authors ...

IntroductionModern broiler chickens are most certainly a most visible manifestation of genetic advancements. At hatch, a Cobb500 broiler weighs 42 grams. This newborn chick grows 31 % (55 g/bird) in just twenty-four hours. By day 35 of age, this chicken reaches a body weightof 2,521 grams, representing 5,902 % relative to hatching mass (Cobb-Vantres 500, 2022). Genetic selection, food, health, and ...

1. IntroductionPoultry and mycotoxins have been closely linked for several decades, as they are one of the most sensitive animal species to the toxic effects of mycotoxins. In the poultry industry, the ingestion of aflatoxin B1 (AFB1) lead to the impairment of all the essential productive parameters [1,2] and decreased resistance to common infectious diseases due to the depression of the humoral a ...

1. Introduction Mycoplasma synoviae (MS) and Mycoplasma gallisepticum (MG) are the most important Mycoplasma species for commercial poultry in Mexico. For decades, these species have been recognized as the cause of chronic respiratory disease (CRD) [1–3]. In addition, they decrease the fertile egg production in broiler breeders, cause late-stage embryonic death, or result in the births of in ...

INTRODUCTIONFluoroquinolones are the third generation of quinolone development. Nalidixic acid and pipemidic acid are examples of the first generation and currently have limited activity against Gram-negative bacteria. Fluorinated 4-quinolones were introduced to the market in the 1980s and were the top of the line antibiotics, offering a broad spectrum of activity and high efficacy in a wide range ...
