[QUOTE="Willow Springs, post: 690314, member: 9002"] Actually the highest nutritional needs are at peak milk yield and re-breeding which usually come together 30-60 days after calving. The cows should be calving at the same time as the best grass is coming; basically the same time the wild ungilates are birthing in your area. We do find quite a bit of feed savings on the cows in the last trimester though; they do have higher needs, but the weather is also much warmer in April/May. Dick Diven suggests May 17 in our area; we are north of Edmonton, Alberta. We start calving earlier than that; about May 1st. I want to be done calving by the first week of June if possible. As Dun said the later calves don't do well on the later summer grass. We have found that the mid June and later calves do poorly. My thoughts are that by the time they start eating any amount of grass it is starting to decline in quality by early to mid-August. The cows are definitely more fertile when calving in June though; most will cycle in 20-30 days and stick to the service; even first calf heifers. [/QUOTE]
