At the bottom of my father’s papers that Mum and I sorted through after he passed away some years ago was a document titled “Breeding Tables”. It lists the main types of domestic farm animals together with information on the duration of various breeding aspects. I came across the document again earlier today and decided to create a blog article outlining the core content. Here goes!
