🛑When do you start preparing your cows for AI?
The comment from a client below speaks volumes about breeding success - planning for AI shouldnt be an after thought, it should be a part of your yearly business model.
✅ DID YOU KNOW… the majority of programs that achieve lower than expected outcomes are a direct result of something that happened (or didn’t happen) in the planning & implementation stages of the program?
WHEN SHOULD YOU START PLANNING?
➡️ As early as possible!
➡️ It takes weeks for an egg to develop on a cows o***y and be able to respond to reproductive hormones and processes.
➡️ Any management changes in the 8 week period BEFORE AI or joining can and do impact the results.
➡️ Management of a cows body condition and your breeding objectives should be thought about year round to get the best results.
➡️ Breeding season is also a busy time for service providers such as vets, techs and repro centres so make sure you get your preg testing, semen testing and collections booked in early!
WHAT SHOULD I BE MANAGING?
🔶 Nutrition - the big one! Cows must come into joining on a rising plane of nutrition, actively maintaining or ideally, gaining weight. This allows the cow to respond to the reproductive hormones correctly & gives her the best shot at maintaining that pregnancy. Any changes to nutrition like the addition or removal of supplements, changing paddocks or changing dry matter type can all lead to nutritional fluctuations, keep this to a minimum in the 8weeks before and after joining to maximise reproductive potential.
🔶 Herd Health - ensure cattle are vaccinated for reproductive diseases and other diseases relevant to your region, and get boosters done several weeks before the day of AI. This reduces the risk of embryo loss from disease incursion and gives the cow enough time to get over the small stress of vaccination and handling associated with it.
🔶Pregnancy testing, repro tract scoring & evaluation - not only does preg testing prior to AI help with identifying animals that shouldn’t be included in the program but it also gives you the chance to conduct a repro tract score so that you can set expectations for pregnancy based on the physical attributes of each animal. This is particularly useful in heifers as they have no prior repro history and it can be hard to pre-determine success rates.
