Virocon - https://imnpyrophos.in/ols/products/v... Chickens are primarily kept for their meat and eggs, and are an important source of food for many people around the world. They are also commonly used in scientific research, particularly in genetics and developmental biology, due to their relatively simple genome and embryonic development. Chickens have a lifespan of around 5-10 years and are social animals that form complex hierarchies within flocks. They are known for their distinctive vocalizations, which vary depending on the situation and can convey a wide range of emotions. Overall, chickens are fascinating and important animals that have played an important role in human history and continue to do so today. The commercial importance of these types of birds has stimulated investigation of their basic physiology. For example, selection for increased numbers of eggs laid has resulted in strains of chickens that lay 250–300 eggs per hen annually, while the tendency for these strains to cease laying and incubate their eggs has been nearly eliminated. The most significant environmental cue for reproductive activity in birds is the photoperiod, especially in chickens. Light that affects reproductive stimulation and timing is perceived by photoreceptors that are located in the hypothalamus. Many experiments has shown that light must pass through the avian skull and that the pineal gland and eyes are not critical for perception of daylength.
