Calving at 21 months fits spring-calving herd i

摘要

Dylan and Hannah Harries had been calving heifer replacements at 23.5 months, but experimented with earlier breeding in the New Zealand Friesian cross Jersey herd in 2017, calving heifers at the end of January at 20.9 months, instead of May.The couple, who run Tyddyn y Eglwys, near Llanfyrnach, Pembrokeshire, in a joint venture with farm owners Kim and Bryony Petty, are in their third year of using this approach and are reporting multiple benefits.
