The photoreaction which takes place between benz [a] pyrene and DNA by irradiation at 365 nm leads to a covalent combination. To ascertain the reactive sites of DNA, a sample of the macro­ molecule has been precipitated after irradiation in the presence of benz [a] pyrene and hydrolized; among the products of hydrolysis four different fluorescent substances have been isolated, one of which was ...

The achievement of a 365-day calving interval requires an early resumption of ovarian activity, an excellent oestrus detection, and a high first-service conception rate. Especially the inability to detect oestrus and to mate the cows by 60...
