Management by providing the ability to introduce elite genetics into the cow herd for a small price and breed many cows at one time, respectively. The 2018 Beef Cow and Heifer AI Breeding Protocols are available online. However, if AI is not for you, synchronization can be utilized within natural service settings to group cows together for the bulls to breed. For more information on NS protocols and bull to cow ratios, read the Using Estrous Synchronization in Natural-Service Breeding Situations factsheet. In addition, consider how long the breeding season will be. A 60-day breeding season will give cows three opportunities to become bred. Adding an AI or estrus synch program gives them an extra chance, so four opportunities to become bred during the same 60 days. Lastly, keep in the back of your mind to conduct pregnancy checks early after bulls are pulled (45 days) to aid pasture and feed savings as we are going into another dry summer. The earlier preg check can occur, the sooner we can pull open cows off of valuable pasture. as they have difficulty resuming cyclicity and rebreeding early due to increased nutrient demands of growth and lactation requirements of their first calf at side. Depending on the number of pastures or lots available, running this group of young and old cows separate from the brood cow herd can make management easier through the summer and fall. For example, if it gets dry again, old cows may need to be the first into town, while young cows can be drylotted with cost effective feedstuffs until fall grazing season arrives. Pay Attention to Young & Old Cows Consider sorting off any young or old cows that need some supplementation or extra TLC moving from calving to breeding season. Two-year old cows may fall into this category LIMOUSIN Today | 165
