SEARC Agricultural Research 2017

Southeast Agricultural Research Center, Agricultural Research 2017. Topics include grazing and supplemental feed for beef cattle, forage, pasture, hay, grasses, legumes, tillage, fertilizer, corn, soybeans, wheat, and soil health and variability.

Including Legumes in Bermudagrass Pastures

Use of legumes in bermudagrass pastures did not affect summer cow gains in 2016. Forage availability was also similar where ladino clover was used in the Legume system compared with where Nitrogen (N) alone was used. Estimated forage crude protein (CP) was greater for the Legume than the Nitrogen system in early summer, but was similar by mid-summer.

Effects of Supplementation with Corn or Dried Distillers Grains on Gains of Heifer Calves Grazing Smooth Bromegrass Pastures

A total of 90 heifer calves grazing smooth bromegrass pastures were used to compare supplementation with 0.5% of body weight per head daily of corn or dried distillers grains (DDG) in 2014, 2015, and 2016. Daily gains of heifers supplemented with corn or DDG were similar (P > 0.05).

Effects of Various Grazing Systems on Grazing and Subsequent Finishing Performance

A total of 280 mixed black yearling steers were used to compare grazing and subsequent finishing performance from pastures with ‘MaxQ’ tall fescue, a wheat-bermudagrass double-crop system, or a wheat-crabgrass double-crop system in 2010, 2011, 2012, 2013, 2014, 2015, and 2016. Daily gains of steers that grazed MaxQ fescue, wheatbermudagrass, or wheat-crabgrass were similar (P > 0...

Effects of Interseeding Ladino Clover into Tall Fescue Pastures of Varying Endophyte Status on Grazing Performance of Stocker Steers

Sixty-four yearling steers grazing tall fescue pastures were used to evaluate the effects of fescue cultivar and interseeding ladino clover on grazing gains and available forage. Fescue cultivars evaluated were high-endophyte ‘Kentucky 31,’ low-endophyte ‘Kentucky 31,’ ‘HM4,’ and ‘MaxQ.’ Steers that grazed pastures of low-endophyte ‘Kentucky 31,’ ‘HM4,’ or ‘MaxQ’ gained...

Evaluation of Supplemental Energy Source for Grazing Stocker Cattle

A total of 108 steers grazing smooth bromegrass pastures were used to evaluate the effects of supplemental energy source on available forage, grazing gains, subsequent finishing gains, and carcass characteristics in 2014, 2015, and 2016. Supplementation treatments evaluated were: no supplement, a supplement with starch as the primary source of energy, and a supplement with fat as...

Including Legumes in Bermudagrass Pastures

Use of legumes in bermudagrass pastures has often increased summer cow gains. Forage production was greater where ladino clover was used in the Legume system than where Nitrogen (N) alone was used in the first sampling, but the reverse was true in midsummer. Estimated forage crude protein during 2015 was greater for the Legume than the Nitrogen system in the first and last...

Effects of Supplementation with Corn or Dried Distillers Grains on Gains of Heifer Calves Grazing Smooth Bromegrass Pastures

A total of 60 heifer calves grazing smooth bromegrass pastures were used to compare supplementation of 0.5% of body weight per head daily of corn or dried distillers grains (DDG) in 2014 and 2015. Daily gains of heifers supplemented with corn or DDG were similar (P > 0.05).

Effects of Various Grazing Systems on Grazing and Subsequent Finishing Performance

A total of 240 mixed black yearling steers were used to compare grazing and subsequent finishing performance from pastures with ‘MaxQ’ tall fescue, a wheat-bermudagrass double-crop system, or a wheat-crabgrass double-crop system in 2010, 2011, 2012, 2013, 2014, and 2015. Daily gains of steers that grazed MaxQ fescue, wheatbermudagrass, or wheat-crabgrass were similar (P > 0.05...

Evaluation of Supplemental Energy Source for Grazing Stocker Cattle

Seventy-two steers grazing smooth bromegrass pastures were used to evaluate the effects of supplemental energy source on available forage, grazing gains, subsequent finishing gains, and carcass characteristics in 2014 and 2015. Supplementation treatments evaluated were: no supplement, a supplement with starch as the primary source of energy, and a supplement with fat as the...

Effects of Various Forage Systems on Grazing and Subsequent Finishing Performance

A total of 200 mixed black yearling steers were used to compare grazing and subsequent finishing performance from pastures with ‘MaxQ’ tall fescue, a wheat-bermudagrass double-crop system, or a wheat-crabgrass double-crop system in 2010, 2011, 2012, 2013, and 2014. Daily gains of steers that grazed ‘MaxQ’ tall fescue, wheat-bermudagrass, or wheat-crabgrass were similar (P > 0.05...

Effects of Supplementation with Corn or Dried Distillers Grains on Gains of Heifer Calves Grazing Smooth Bromegrass Pastures

Thirty heifer calves grazing smooth bromegrass pastures were used to compare supplementation with 0.5% of body weight per head daily of corn or dried distillers grains (DDG). Daily gains of heifers supplemented with corn or DDG were similar (P > 0.05).
