The effects of rumen protected methionine supplementation on the performance of primiparous dairy cows using the Presynch‐Ovsynch protocol

The purpose of this study was to examine the effects of rumen‐protected methionine (RPM) supplementation on the reproductive and productive performance of primiparous dairy cows fed two levels of protein. The Presynch‐Ovsynch protocol was used to synchronize 36 lactating Holstein cows that were assi...

Description
Summary:The purpose of this study was to examine the effects of rumen‐protected methionine (RPM) supplementation on the reproductive and productive performance of primiparous dairy cows fed two levels of protein. The Presynch‐Ovsynch protocol was used to synchronize 36 lactating Holstein cows that were assigned randomly to one of six dietary treatments: (1) 14% CP and without RPM diet (14CP‐0RPM; n = 6), (2) 14% CP and 15 g/head/day RPM (14CP‐15RPM; n = 6), (3) 14% CP and 25 g/head/day RPM (14CP‐25RPM; n = 6), (4) 16% CP and without RPM diet (16CP‐0RPM; n = 6), (5) 16% CP and 15 g/head/day RPM (16CP‐15RPM; n = 6), and (6) 16% CP and 25 g/head/day RPM (16CP‐25RPM; n = 6). Independent of CP levels, feeding RPM had reduced the calving interval (P
