There are 7,000 livestock entries at this year's Royal Welsh Show - from rare breed sheep to huge commercial beef cattle. Anna Hill meets the farmers with a passion for showing their animals including a sister and brother pair who've picked up rosettes for their Welsh Black Cattle.

We also hear from a scientist who grows duckweed on slurry with the aim of producing a new source of protein for animal feed, and quiz Wales' Shadow Rural Affairs Minister over water pollution, bovine TB and funding for farming.
