dose she still have her calf on ? and is she giving you a good letdown ? alfalfa hay will help with the cream line , and if she is holding up for the calf then you will get less cream till you wean her calf ,
I had a customer ask about my cream line right now , as it is skimpy , and I explained that I was calf sharing , and I was separating the calves at night and leaving 1/2 for the calves when I milked ,as the cream is in the hind milk, which means the calves get the creamier milk , and that once I wean calves the cream line will jump up , some people do not believe this but it is true , I had 1 Swiss cow that held up so bad ,that I had to pull her calf for 4 days before she gave me a good let down , another trick you can try is to separate the calf for a couple hours , and tie the calf where it can just
reach her side but not the udder , and when she lets down milk 2 or 3 quarters for the house and then let the calf have the other quarters that you did not milk ,and see if there is improvement in the cream line
