Abstract

1. Accurate sex identification of one-day-old chicks is crucial in layer poultry production. Establishing an early sexing method during the chicken embryonic period is essential for animal welfare. However, PCR-based sexing has limitations in terms of specialised equipment and is time-consuming.2. This study presents a rapid, simple and fluorescent visual technique for chicken sex identification based on Loop-mediated isothermal amplification (LAMP)-clustered regularly interspaced short palindromic repeats (CRISPR)/CRISPR-associated protein 12a (Cas12a). It targets the chicken Z chromosome gene DMRT1 and W chromosome-specific fragment EE0.6 using designed primers and sgRNA. The LAMP amplicon is cleaved by Cas12a, producing a fluorescent product detectable by a portable light apparatus.3. The method has high sensitivity, capable of detecting as few as two copies per microlitre of the EE0.6 template and 20 copies per microlitre of the DMRT1 template. This has significant potential for distinguishing chicken embryo gender very early in embryonic development.

期刊介绍： From its first volume in 1960, British Poultry Science has been a leading international journal for poultry scientists and advisers to the poultry industry throughout the world. Over 60% of the independently refereed papers published originate outside the UK. Most typically they report the results of biological studies with an experimental approach which either make an original contribution to fundamental science or are of obvious application to the industry. Subjects which are covered include: anatomy, embryology, biochemistry, biophysics, physiology, reproduction and genetics, behaviour, microbiology, endocrinology, nutrition, environmental science, food science, feeding stuffs and feeding, management and housing welfare, breeding, hatching, poultry meat and egg yields and quality.Papers that adopt a modelling approach or describe the scientific background to new equipment or apparatus directly relevant to the industry are also published. The journal also features rapid publication of Short Communications. Summaries of papers presented at the Spring Meeting of the UK Branch of the WPSA are published in British Poultry Abstracts .
