FEED•LOT December 2018 19 is less than ideal, consider sup- plementing before cows start to lose condition. Once cows lose condition, it can be expensive to gain back. A proactive approach to supplementation is best. "Cattle supplements with intake control properties can provide nu- trients to complement your forage and maintain cow body condition through all seasons," says Back- es. "If cows need more nutrients, they'll consume more supplement. If cows are getting the nutrition they need from forages, they'll consume less." Backes' biggest takeaway? Nev- er let your cows have a bad day. "Set cows up for success by pro- viding them with quality mineral and protein supplements," says Backes. "A good, year-round nutri- tion program supports improved breeding rates." Visit purinamills.com/breeding to learn more about better-than-average breed- ing results. FL in which a cow calves impacts how quickly she will return to estrus. "A good body condition score can decrease the postpartum in- terval so cows get bred earlier in the breeding season," says Back- es. "Cows bred earlier in the sea- son have calves born early in the calving window, which results in more weight at weaning. And, when a calf gains between 2.25-2.5 pounds per day, every heat cycle is worth about 50 pounds." A body condition score of 6 is ideal, and every point matters. Re- search shows that when cows calve with a body condition score of 6, 98 percent showed estrus by day 40 of the breeding window and 90 percent were confirmed pregnant by day 40.1 The same research showed a drop in BCS to 5 resulted in only 80 percent in estrus and 65 percent confirmed pregnant by day 40. At BCS 4, only 56 percent were in estrus and 43 percent were con- firmed pregnant. Act on BCS, Forage Conditions Turning valuable BCS data into action is key. Monitor scores reg- ularly so you can adjust nutrition plans in real-time. Don't forget to keep an eye on forage quality.
