The “Lazy L” Gets You Ready for Herd and Stocking Rate Changes

A beef producer needs a set of “liquid cattle” – the group that is easy to round up and sell as weather changes, feed becomes short or the labor force changes. Selling this group creates opportunity for the remaining herd by lessening the demands on the operation. Life does not always go the direction that we want. And so, there may be truth in the saying, “one person’s loss is another person’s gain.” But with good planning, both should gain, even if the challenge was not desired.

Plan 70%, Leave 30% Flexible

Good advice I received when I started with the North Dakota State University Extension Service was plan 70 percent of your day and leave 30 percent open to respond to the issues of the day. If the day is booked solid, it has a high probability of ending with frustration because you have no time to respond to issues. The same is true in beef production: Book 70 percent of the ranch with core programs, core cattle, core pastures and forage, and focus the other 30 percent on meeting the issues of the year. Good years: more cattle, more forage, more labor; bad years: fewer cattle, less forage, less labor. This gives you the adaptability that is critical for long-term sustainability. This principle is certainly obvious in the world of available cattle feed.

The biggest mistake producers can make is to delay marketing decisions when feed runs short because that assures less flexibility. So it’s a good idea to start the grazing season with a plan for which cattle you would sell should summer weather not match expectations. The simplest approach is what I call a “lazy L,” a proactive management plan that evaluates cow-calf numbers and determines in advance how many pairs should be turned out to core pasture grass and allows you to plans ahead for easier adjustment to inventory should adjustments be needed.

First, let’s build a calving distribution table from the calving information. Take a sheet of paper and make five columns listing dates when cows calved across the top: first 21 days, second 21 days, third 21 days, fourth 21 days and late. Then add rows for each age of cow you have in the herd. Now you have a table with all your cow ages down the left-hand side and calving cycle across the top.Complete the table by going to your calving book and marking down each cow in the appropriate box in the table. For example, cow H8220 is a 4-year-old that calved 30 days into the calving season. Place a mark in the 3-year-old row and second 21 days column. Cow G7108 is a 5-year-old that calved 15 days into the calving season and would get marked in the 4-year-old row and first 21 days column. When finished, you will have a table that shows the distribution of your current calving season by cow age. This identifies older cows and cows not calving on time.

Determine how many “liquid cows” you need to market by drawing a “lazy L.” Adjust the “lazy L” according to need. If the goal is to have 20 percent of the herd as “liquid cows,” then move the “lazy L” up or down until the number of old and or late-calving cows approximates the number of needed “liquid cows.” If you manage more than one herd, you can put everything below and to the right of the “lazy L” into the “could be sold” pasture. Many of these cows will work just fine for someone else, and will clean up and fine-tune your own operation.

The Dickinson Research Extension Center drew a line between the 9- and 10-year-old cows and a line between the third 21 days and the fourth 21 days to create our “lazy L.” In a previous dry season, the center sold everything below and to the right of that “lazy L.” While one is at it, add the wild, poor-mothering or poor-milking cows as well.

Getting back to where we started, producers need to set up their day with 70 percent planned work and apply the same principle to the operation, with a 70 percent allocation of resources to core programs. By doing so, the day goes better and change is prepared for, more tolerable and less stressful.

  1. John Hoyt from Jolly Roger Angus always used to say ” It costs just as much to run a bad one as it does to run a good one.” All the dingbats, screaming pyscho bossies, man eaters, drop and walks, calf killers, fence crawlers, herd quitters, etc must go. I have not touched a calf in years and went completely hands free in 2017. It is possible, do not put up with garbage.

  2. Great article on being prepared. For someone like me that still calves rear round in southeast Texas and has not yet developed a liquidation plan, Johann Zietsman’s method for selecting for efficiency may be more appropriate (but more complicated) for determining your liquid cows. Part of his ranking is based on inter calving interval and time of year she rebred for each animal. A higher ranking cow will have a shorter inter calving interval that rebred during the worst forage and environmental conditions for that year. This is a more complicated method but will help to insure that you keep your “best” cows (based on your particular environment, management practices, and a selection criteria emphasizing efficiency) for rebuilding the herd after liquidation. He shows a picture of a 25 year old cow in one of his presentations that produced 25 calves over her life (one set of twins) that looks like some of my “best” looking 8 year olds
