They graze for approximately three months before coming back in for a short, sharp finishing period. While it means that they are older than 16 months-of-age at slaughter and thus sold for a flat price, off the QPS grid and non-quality assured, Harry likes the cheap weight gain that he achieves during the grazing period.“Last year we nearly averaged 1.8kg of weight gain per day as a group,” he told me when I visited the farm in early March.
