In adult ewes, we tested whether ovarian function, including the response to short-term supplementation, was affected by the nutrition of their mothers during the pre-/postnatal period. A 2x2 factorial was used with nutrition in early life (low or high) and a 6- day supplement (with or without) as factors. All ewes received 3 prostaglandin injections 7 days apart, and the supplement (lupin grain) was fed for 6 days from 2 days after the second until the third prostaglandin injection. We measured reproductive and metabolic hormones, studied follicle dynamics (ultrasonography), and evaluated granulosa cell numbers, aromatase activity and oestradiol concentrations in follicular fluid in healthy follicles at Days 3 and 7 of supplementation. Ovulation rate was increased by 25% by exposure to high pre-/post-natal nutrition (1.5 versus 1.2; P < 0.05), in association with a small decrease in FSH concentrations (P = 0.06) and a small increase in insulin concentrations (P = 0.07). The number of healthy astral follicles was not affected. Acute supplementation increased the number of granulose cells (3.7 ??0.2 vs 3.0 ??0.2 million; P < 0.05) in the largest follicle, and the circulating concentrations of oestradiol (4.6 ??0.3 vs 3.9 ??0.3 pmol/L; P < 0.05) and glucose (3.4 ??0.03 vs 3.3 ??0.03 mmol/L; P < 0.01). Both early life nutrition and acute supplementation appear to affect ovulation rate through changes in glucose-insulin homeostasis that alter follicular responsiveness to FSH and therefore oestradiol-FSH balance.

John Hodgson (1937?2018) is renowned worldwide as a passionate and principled researcher, dedicated to the study of interactions between grazing livestock and pasture
sward, and to whole-system management of grassland. He published over 250 scientific outputs during his 50-year career, and inspired generations of grazing ecologists.
Following his upbringing on a mixed-livestock farm in the Yorkshire Dales, John received BSc, PhD and DSc from the University of Leeds, UK. He worked in
research institutes in Hurley, England and Penicuik, Scotland, before taking a Chair in Agronomy at Massey University, New Zealand in 1986. There, he progressed to become Head of School for the Environment. John retired from university life in 2002, but never left academia. John?s global research legacy is reflected in the international authorship of this memorial review. His international impact is demonstrated by the supervision of over 50 PhD students from all over the world, and by his knowledge-sharing travels to South America and China. His peers will remember him as a thoughtful and collaborative scholar. His students will remember him as an inspiring and caring mentor. He helped to revolutionize the way that grasslands are managed, in the face of global environmental change and increasing demand on grazed systems. John lost a long battle with Parkinson?s disease in October 2018 and is survived by his wife, Ruth, and five children. His own research was often dedicated to his father, Dick Hodgson, and the first author of this tribute wishes to do the same.
