Scanning maiden heifers fed low DMD silages

 We visited a farmer outside Kiltegan, Co. Wicklow, who presented maiden dairy heifers, for pregnancy assessment. Pregnancy rate to first service was close to 90% in a group of 40 heifers. The heifers were fed poor quality baled silage with a DMD of 52 to 59. The heifers were also fed 4k.g of a 21% protein ration. He claimed that this diet worked extremely well for another colleague who was implanting embryos.
