Our yield per cows been down a bit most of the winter but the fat has been usually over 4.5% which is pretty decent for an all Holstein herd. Last winters winter kill left most all our hay fields instead of mostly lush alfalfa and 16-20% protein to Timothy and weeds and 10-12% protein. This winters been bad for bare ground and ice the last 6 weeks so we have enough corn seed ordered in case we need it to jump 50% in acreage over last year with 40% ordered being BMR. For whatever reason and we'll take it the yield per cow is up 2-3 kg/cow but our MUN in the milk tank is still only 9 (milk urea nitrogen,way to test if your cows are getting a balanced diet,like to see MUN between 12-15) so I don't think the silage changed. Be interesting to see with the extra yield how much percent fat well loose. We culled a few and dried a group off and milkings average came up and the tank never really dropped even though we're down 5+ cows in the tank this week. Have 2-3 getting close to calving right away.
