Blazin' Grazin' And Other Wild Things
Stocking rate is the grazing decision that affects nearly everything else on the land — cattle performance, native pasture health, wildlife habitat, prescribed fire options and long-term ranch profitability. In this episode of Blazin’ Grazin’ and Other Wild Things, John Weir talks with Laura Goodman Ph.D. and Mark Turner Ph.D. about what stocking rate really means, why timing matters, and why grazing density is not the same thing. They explain how heavy stocking can reduce cow breed-up, calf weaning weights and individual gains, while also weakening the plant community and shrinking future forage production. Key takeaways: * Stocking rate means animals, acres and length of time. * Moderate stocking often provides the best balance between animal performance and gain per acre. * Rotational grazing cannot fix an overstocked pasture. * Bigger cows require more forage than the cows many ranches were stocked for decades ago. * Grazing exclosures, clipping, Web Soil Survey and RAP can help producers estimate forage and adjust before drought creates harder choices. Detailed timestamped rundown 00:00–02:13 — Intro and episode setup The Oklahoma Conservation Commission sponsors a message and show intro that set up the episode’s focus: stocking rate, cattle grazing, pasture health, wildlife, and ranch profitability. 02:13–03:19 — Why midsummer is a good time to check stocking rate John introduces the topic, and Laura explains that Oklahoma native pastures grow most warm-season forage in May and June. By July, producers can better evaluate how much forage they have for the rest of the season. 03:19–05:56 — What stocking rate actually means Laura defines stocking rate as the number of animals on a unit of land for a length of time. She explains why asking “How many cows can I run on this acreage?” is incomplete without knowing how long the animals will graze. 05:56–08:42 — Benefits of proper stocking rate The group discusses how proper stocking supports the long-term sustainability of the plant community, helps maintain dominant forage species and reduces pressure on sensitive areas such as streams. 08:42–12:14 — Animal performance under heavy stocking Laura explains research showing that heavy stocking can reduce cow breed-up, increase open cows, lower calf weaning weights and reduce individual gains in stocker cattle. 12:15–15:40 — Why grazing systems cannot fix overstocking The conversation turns to rotational grazing. Laura explains that rotation can modestly improve plant productivity and grazing efficiency, but it cannot double forage production or make up for running too many animals. 15:40–17:27 — Utilization and the mowed-lawn problem John explains why some producers want every blade of grass used evenly, but that is not always realistic or desirable. A pasture does not need to look like a manicured lawn to be properly managed. 17:27–20:15 — Why uneven grazing can help wildlife Laura discusses how grazing management thinking has changed. Varying plant heights, open space under the canopy and patchy structure can benefit wildlife and create better habitat diversity. 20:15–22:08 — Forage quality, long rest and patch burning The group talks about cattle preference for young, higher-quality forage. Laura explains why patch burning works well: it removes old growth, creates fresh regrowth and attracts grazing to areas that need use. 22:10–27:16 — How to measure forage with grazing exclosures Laura walks through how to use cattle panels, T-posts and a clipping hoop to estimate pasture production. She explains why native pasture is better measured by clipping than by using a grazing stick. 27:16–29:58 — How many samples and how many years? Mark asks how many exclosures or samples are needed. Laura recommends multiple locations and multiple years because Oklahoma forage production can swing widely from dry years to wet years. 29:58–32:45 — Measuring utilization and changing grazing distribution The group explains how clipping outside an exclosure can estimate what cattle used. They also discuss moving protein, salt, mineral and using fire to draw livestock into underused areas. 32:45–36:48 — RAP and Production Explorer Laura introduces the Rangeland Analysis Platform as a web-based tool that uses satellite imagery to estimate cover, biomass and production. She explains that Production Explorer can estimate current production and calculate stocking rates. 36:48–38:54 — Bigger cows require more forage John notes that many ranches still use older stocking assumptions even though cattle have gotten larger. Laura explains that a 1,300-pound cow consumes much more forage over a season than a 1,000-pound cow. 38:55–40:20 — Adaptive management and midseason decisions Laura explains how checking forage in midsummer can help producers decide whether to move cattle, sell animals, feed hay, retain calves longer or keep more replacements. 40:21–43:45 — Drought economics and flexible herd structure Mark connects the topic to wildlife carrying capacity. Laura explains that drought-related destocking can affect ranch economics for years and that a smaller base cow herd with flexible stockers or retained ownership can reduce long-term risk. 43:46–45:11 — Take half, leave half and harvest efficiency Laura clarifies that the old “take half, leave half” rule is often misunderstood. In stocking calculations, the goal is usually to allocate about 25% of total available productivity to livestock consumption. 45:11–48:39 — The stocking rate calculation Laura lays out the math: forage production per acre × number of acres × 0.25 harvest efficiency, then divide by animal demand and grazing days to estimate how many animals a pasture can support. 48:39–50:07 — More cows do not always mean more profit John explains that more animals can mean more input costs, more overuse, lower gains, lower weaning weights, lower body condition and more hay feeding. 50:09–51:20 — Stocking rate is the foundation The group closes by emphasizing that stocking rate is the number one grazing decision because it affects cattle, plants, wildlife, prescribed fire and long-term ranch economics. 51:20–51:58 — Outro The episode closes with a reminder to subscribe and visit the podcast website.
