When to turn beef cattle out on jump pasture
Grass is greening only feeding beef cattle hay or forage reserves a bit longer, rather than grazing, could maintain pasture health
Leaving beef cattle to snack on feed reserves a bit longer this spring, rather than turning them out on newly light-green pastures may be the fashion to go, a Southward Dakota State University professor says.

On the question of when to turn beef cattle out on spring pastures, professor Pat Johnson says the considerations include hay reserves, the cost of purchasing additional feed, and the bear on of early on grazing on pasture grasses.
Some questions to ask include:
- How long should you continue to feed stored forages, to delay the affect of grazing on pastures?
- How early can yous turn out, relieving the cost of feeding?
- Which pasture do y'all graze first?
The answer to these questions is: It depends! Beef producers may have several options, depending on pasture resources, stored feed resources, and power to be flexible in grazing options.
Continue feeding livestock a few weeks longer
If feed reserves are available, feeding livestock a little afterwards into leap provides pasture grasses with time to shift from dependency on reserves to utilizing photosynthesis for energy. If grazing is initiated too early, production for the remainder of the growing season can be reduced, Johnson said.
Graze tame grass pastures earliest
Admission to pastures planted with introduced cool-flavor grasses, such as crested wheatgrass and smooth brome, provides early season flexibility and avoids early grazing on native pastures which may compromise production later on in the flavour, Johnson said. These pastures are typically ready to be grazed two or more weeks before native pastures.
Flash grazing winter pastures
A recent study demonstrated that native winter pastures could be grazed in mid-May at most 25% relative use without a subtract in stockpiled winter forage. Exceeding 25% utilize or extending grazing into mid-June, even so, could reduce forage in those pastures that'south needed for next wintertime.
Wait to graze native pastures until grass is "gear up"
Research suggests that grass plants are most vulnerable to grazing before they have formed three new leaves. Knowing how many growing degree days are required to reach the three-leaf stage provides a general "rule-of-pollex" nearly plant evolution. The date that grasses reach the three-leaf stage varies considerably, so examining the important plants in your own pasture is recommended.
I style to come with a date to brainstorm examining your grasses is to use "growing degree days" (GDD, base 32 degrees later March 1).

GDD is calculated for each twenty-four hours as (Tmax + Tmin)/2 – Tbase, where Tbase is 32. GDD is then summed for all days after March 1. For introduced grasses, the iii-foliage stage by and large requires accumulation of about 500 GDD; many native cool-season grasses require about 1200 GDD. The calendar date when these growing conditions occur varies considerably from one location to some other and from year to twelvemonth.
A no-no: Same pasture, same time, twice
A "rule-of-thumb" which should exist remembered at spring pasture turn-out is "never graze the same pasture at the same fourth dimension of the yr, ii years in a row."
While many operations, of necessity, have a calving pasture which is grazed at the same time of the year, every yr, nearly operations can vary where cows and calves begin grazing later on calving is completed.

"The management goal is to distribute defoliation force per unit area on desirable species to unlike times of the flavour in different years," Johnson notes. "If a pasture is grazed at the aforementioned time every year, the vigor of institute species which are most vulnerable at that flavour volition exist reduced and they may eventually be eliminated from that pasture."
