In order to evaluate the efficiency of these methods, the scientific community need a reliable, easy to use and cost-effective in-ovo invasive sexing method. Figures Abstract Chicken meat and eggs are important sources of food for the world population. In order to establish such an assay, we addressed the performances of existing methods and, at the same time, developed two new assays based on PCR and real-time quantitative PCR Q-PCR respectively. Poultry Trends. The technology for sexing sperm has not changed greatly in the past 7 years, but refinements have speeded up the process and reduced damage to sperm. Samples were then centrifuged for 5 minutes at g at room temperature. Nevertheless, none of the previously developed methods was neither assayed in terms of performances nor fully satisfied all requirements of a reference assay such as sensitivity, specificity, robustness, rapidity and low-cost. Both new assays performances were extensively evaluated on chicken embryo samples. And is it possible to compare cities through a gendered lens? It also brings a gendered focus to key debates in urban studies such as urban comparativism. Overview of sexing sperm. All relevant data are within the manuscript and its Supporting Information files. How to resist heteronormative and patriarchal forces that continue to haunt the cityscape? Data Availability: Other approaches raise a biological concern since egg sexing must be run under non-sterile environment i. How and when and who can claim the right to the city?

Tronico provided support in the form of salary for LC but did not play any role in the study design, data collection and analysis, decision to publish, or preparation of the manuscript. Meanwhile, in India, calls for a safe city for women continue to dominate public debate. Sexing the City aims to unravel this proliferation of new gendered and sexed dynamics and subjectivities within recurring and persistent heteronormative discourses. Brain was chosen for DNA extraction since it is a soft tissue easy to aspirate with a P pipette. Fertile eggs were incubated in a dedicated incubator Masson, Soyans France at However, this technology is characterized by high costs, complexity of implementation and lower pregnancy rates than with control sperm.

Among these approaches, odour analysis represents the sole non-invasive technique that does not require eggshell opening. Nevertheless, none of the previously developed methods was neither assayed in terms of performances nor fully satisfied all requirements of a reference assay such as sensitivity, specificity, robustness, rapidity and low-cost. In order to evaluate the efficiency of these methods, the scientific community need a reliable, easy to use and cost-effective in-ovo invasive sexing method. How to feel safe while navigating the city autonomously? Data Availability: In Sexing the City we wish to unpack the gendered dimensions of rapid urban changes taking place today through the themes of autonomy, respectability and precarity. Poultry Trends. Nevertheless, sexed, frozen bovine sperm are being produced commercially in many countries, although from a limited number of bulls. In other words, the reference assay serves as a standard to validate future new non-invasive egg sexing assays. However, this technology is characterized by high costs, complexity of implementation and lower pregnancy rates than with control sperm. Each year, all over the world, around 6 billion male chicks are considered as useless products Source: Competing interests: Tronico provided support in the form of salary for LC but did not play any role in the study design, data collection and analysis, decision to publish, or preparation of the manuscript. Although this technology has been used for many species, the overwhelming majority of pregnancies have been in cattle, nearly all as a result of sperm that were sexed and subsequently frozen. We address questions such as: These assays exploit the genetic differences between males that have two Z sexual chromosomes ZZ and females have one Z and one W sexual chromosome ZW using different genes as markers. How and when and who can claim the right to the city? What impact creative forms of protest can have? Tronico employs Lise Catherinot. Brain was chosen for DNA extraction since it is a soft tissue easy to aspirate with a P pipette. The process of commercialization of sexed sperm has accelerated recently. Because of the slow speed of sexing sperm, fewer sperm are used per insemination dose of sexed than conventional sperm, and pregnancy rates with this product are often only slightly decreased. Ethical and economical concerns emerging from chicken culling need to be solved in the near future. Fertile eggs were incubated in a dedicated incubator Masson, Soyans France at A number of laboratory all over the world are looking for innovative non-invasive sexing methods to determine the sex of chicken in the early stages of the development before hatching.

The technology for sexing sperm has not changed greatly in the past 7 years, but refinements have speeded up the process and reduced damage to sperm. However, up to now, this is not yet a reliable method for egg sexing. However, this technology is characterized by high costs, complexity of implementation and lower pregnancy rates than with control sperm. Tronico employs Lise Catherinot. How to feel safe while navigating the city autonomously? November 9, ; Accepted: Data Availability: It raises ethical and economical concerns that must be fixed as soon as possible, mostly to avoid animal suffering. A number of laboratory all over the world are looking for innovative non-invasive sexing methods to determine the sex of chicken in the early stages of the development before hatching. The process of commercialization of sexed sperm has accelerated recently. Although this technology has been used for many species, the overwhelming majority of pregnancies have been in cattle, nearly all as a result of sperm that were sexed and subsequently frozen. Among these approaches, odour analysis represents the sole non-invasive technique that does not require eggshell opening. A reference in-ovo sexing method that is highly reliable, rapid, user friendly and cost effective to validate ex-ovo approaches is required for the development of non-invasive assays. In the same line with other groups, we exploited the differences betweed males ZZ and females ZW chicken sexual chromosomes. How chicken are cultivated and processed in food industry is no longer acceptable. Overview of sexing sperm. Many countries and companies around the world are running scientific programs in order to be able to determine the sex of living chicken embryos at the early stages of development. Because of the slow speed of sexing sperm, fewer sperm are used per insemination dose of sexed than conventional sperm, and pregnancy rates with this product are often only slightly decreased. Figures Abstract Chicken meat and eggs are important sources of food for the world population. The main application of sexed sperm to date has been to breed dairy heifers to produce female calves. In order to establish such an assay, we addressed the performances of existing methods and, at the same time, developed two new assays based on PCR and real-time quantitative PCR Q-PCR respectively. These assays exploit the genetic differences between males that have two Z sexual chromosomes ZZ and females have one Z and one W sexual chromosome ZW using different genes as markers. As costs decline, sexed sperm will be used increasingly for cattle breeding, horse breeding and niche applications in other species. Competing interests: Indeed, in egg production industry, male chicken are killed at the age of 1-day post-hatching since they are not egg producers.
