How (and Why) These Eastern Canadian Cow-Calf Producers Changed and Defined Their Calving Periods

There are many interconnected variables that affect, or are affected by, calving season. Considerations such as infrastructure and facilities to remove and house bulls following a defined breeding season, herd size, regional market prices, targeted weaning time and labour availability are a few factors that impact a calving period.

These producers did their homework and planned ahead before shifting their calving seasons in order to meet the needs of their particular farms and families.

Spencer Yeo, Nova Scotia – Shorten Calving Period from Twelve to Six Weeks

Six years ago, Spencer Yeo who now farms in Nova Scotia had a large calving window, with the bull in year-round. About 60% of his herd calved during a 12-week timeframe but there were always stragglers which meant a lot of extra nights checking cows. Yeo had a small herd and was selling calves direct from the farmyard. With a mix of weights and smaller calves pulling the average price down, he saw an opportunity for change.

“If you’re going to adjust your calving window, you need to make sure your cows are in good shape to do it successfully.” – Spencer Yeo, Nova Scotia

Yeo aimed to transition to a six-week calving period to help with time management as he also works off-farm full-time. He chose to aim for February calving because it is typically a little warmer then, in his region. It is also a time of year when he has the most free-time, and it was when the majority of his cows were already calving so he was working with the herd versus against them.

The transition occurred within a single year with the breeding season shortened to May 1 through mid-June. Preg checking occurred in August, and any open females were sold. This worked well as cull cow prices were seasonally higher in August versus later in the fall, which resulted in extra income. Bull management includes the option of leasing out for a few months or selling after the breeding season. Yeo replaces the bull every two years, so only has to deal with a bull in the off-season every other year. Continue reading

*Upcoming Webinar* Grazing Game Plan: How to Develop a Grazing Plan- February 9



Grazing is an essential part of raising cattle on the Canadian landscape. Whether you have been managing cattle on grass for years or are just starting, it is important to have a plan. A grazing plan matches animal numbers to predicted forage yields to help balance supply and demand. Ideally, a grazing plan is in place before cattle are turned out. An important first step in developing a plan includes defining goals and objectives for the entire grazing operation. This webinar will cover the basics of developing a grazing plan.

Register for our upcoming webinar on February 9th and hear from two industry experts from western and eastern regions of Canada as well as a producer who will be sharing their practical perspective. The speakers will provide insight and answer your questions about developing and executing a grazing plan that meets your short- and long-term goals.
