OUTPUTS: Resources were used to maintain land, equipment, and livestock so they are available and functional for research purposes. Funding for research comes from other sources. Cows were maintained in early- vs. normal-weaning and low- vs. high-winter feeding treatments to evaluate long-term effects and interactions of treatments. EW steer calves were allocated in equal numbers to feedlot, bale-grazed oats, bale-grazed winter triticale, and to graze unharvested corn. Heifer calves from each weaning treatment were allocated to subsequent treatments of post-weaning development on pasture or in drylot. Four yearling heifers in each post weaning treatment from 2009-10 were fitted with GPS collars to determine grazing behavior when summer grazed. Ewes were used in an experiment to evaluate graded levels of glycerol as a flushing supplement to increase fertility. A field day at the Antelope Station was held Oct 1st. Cattle Research: NRI/5 States Ruminant Consortium research concluded its final year of research at the Antelope station. Cows were either early or normal-weaned, as they have been since 2005. Heifer calves were retained for graduate student research (Nikki Hojer) on heifer development protocols. They were placed into either drylot or range development treatments. Steer calves from both weaning treatments were sent either directly to the UNL Panhandle feedlot or to Ludlow to graze round bales (oats or triticale). Sheep Research: Year two of the sheep research project was completed. Ewes will be ultrasonographed in January to determine pregnancies off CIDR, and again in February to determine pregnancy rates. Year three of the sheep research was started in November 2010, 96 ewes (16 ewes per treatment) were assigned to one of five glycerol treatments, or the 21 days range cake supplementation. Blood samples were collected and will be analyzed for glucose and insulin. Pregnancy determination will be completed on year three sheep via ultrasonography in January and February of 2011. YFA Research: Exclosures were not grazed at Antelope in 2010. However, a final assessment of survival of the 11 populations was taken in July after the plants had made good growth in May and June. Additional data regarding biomass, canopy volume, and reproduction was collected for the last time as well. Alfalfa was interseeded in May 2010. Seedling frequency and seedling height data regarding initial establishment was collected in July 2010. Photosynthetically Active Radiation (PAR) readings were taken in mid-August. This study was the second of two identical experiments at the Antelope Station and was completed in August 2010. Data is currently being analyzed and a graduate student thesis is being written.

Impacts
SHEEP: February ultrasongraphs showed a high rate of pregnancy lost. Lambing rates for all treatments were less than 1 lamb per ewe, due to environmental conditions. The blood samples were analyzed for glucose and insulin. Approximately 10 individuals attended the 2010 field day held Saturday, September 25th. SDSU Faculty spoke on topics such as calf performance as feedlot animals, yellow- flowered alfalfa and heifer development on range. COWS: EW cow weights (663/660kg for HI/LO) and BCS (5.7/5.7 for HI/LO) were higher than for NW cows (weights=635/611kg for HI/LO and BCS=5.1/4.8 for HI/LO) in November as expected due to reduced requirements for dry EW cows compared to NW cows with suckling calves. Pre-calving (February) weights and BCS were lowest for cows in the NW-LO treatment (wt=553 kg, BCS=3.9) and highest for cows in the EW-HI treatment (wt=647kg, BCS=4.8). By EW (August), weights were higher in the EW treatments (629,611; 607,579 kg) and BCS were similiar = (5.2,4.9; 5.1,4.8) for EW-HI, EW-LO, NW-HI, and NW-LO, respectively. Cow pregnancy rates (evaluated in fall) in 2010 ranged from 83 to 97% for the four treatment combinations

Impacts
COWS: EW cow weights (584/571 kg for HI/LO) and BCS (5.1/5.1 for HI/LO) were higher than for NW cows (weights=555/546 kg for HI/LO and BCS=4.8/4.8 for HI/LO) in November 2008 as expected due to reduced requirements for dry EW cows compared to NW cows with suckling calves. Pre-calving (February) weights and BCS were lowest for cows in the NW-LO treatment (wt=546 kg, BCS=4.2) and highest for cows in the EW-HI treatment (wt=584 kg, BCS=4.7). All pre-calving cow weights and body condition scores were lower in spring 2009 than in spring 2008 for all treatment combinations, likely due to the severe 2008/09 winter conditions. By pre-breeding (June), weights and BCS were similar among treatments (619, 603, 614, 593 kg and BCS=4.7, 4.6, 4.6, 4.4 for EW-HI, EW-LO, NW-HI, and NW-LO, respectively). Those similarities continued until EW (August). Cow pregnancy rates (evaluated in fall) in 2008 ranged from 96 to 98% for the four treatment combinations. EWES: Following 2008 treatments, there were no differences in ewe fecundity. Response to 2009 treatments will be measured in early 2010. YELLOW-FLOWERED ALFALFA: Response continues to indicate higher survival in locally adapted alfalfa populations with higher percentage of YFA in their genetic background.

Progress 01/01/08 to 12/31/08
Outputs
OUTPUTS: During the 2008 growing season, intense grazing of alfalfa plants and associated vegetation occurred monthly for one day at exclosures on the Antelope Station. Survival and vigor of grazed and protected alfalfa plants was observed shortly before each grazing treatment. Survival, vigor and associated characteristics were recorded (SD00155-H). In spring/summer 2008, EW and NW heifers grazed separate rangeland pastures at the Antelope Research Station. Heifers will remain in original weaning and winter feeding treatments throughout the study. Cows were maintained in their previous calving and winter feeding treatments to evaluate long-term effects and interactions of treatments. Heifer calves were synchronized and bred AI followed by cleanup bulls; cows were bred natural service. Calves of EW cows were weaned 12 August; calves of NW cows will be weaned in November. EW heifer calves were allocated to 2 groups based on age; groups were randomly assigned to post-weaning environment of range (LI) or drylot (HI). NW heifer calves will be allocated similarly (SD00197-G and SD00H224). Research to evaluate nutrition regimens to improve fecundity in range ewes was initiated in the fall by evaluating response to graded levels of glucogenic precursors in ewe diets immediately prior to breeding (SD00H260). PARTICIPANTS: Participants in SD 00155 include Roger Gates, Chris Misar, Xu Lan and Arvid Boe. Participants in SD00197-g and SD00H224 include Ken Olson, Pat Johnson, Roger Gates, Robin Salverson, Mindy Hubert and Doug Young. Participants in SD00H260 are Julie Walker and Doug Young. TARGET AUDIENCES: SDSU Field Day was held at the Buffalo Community center. Target audience was 40 producers. Research results and current projects and topics were discussed. The overall target audience for this research is livestock producers, range managers, and animal and range scientists. PROJECT MODIFICATIONS: Nothing significant to report during this reporting period.
Impacts
Survival data in June 2008 revealed that locally adapted alfalfa populations with a high percentage of YFA in their genetic backgrounds had the highest survival. Alfalfa populations with lower survival, which were naturally or artificially selected in different environments, tended to be associated with lower persistence in northwestern South Dakota after two seasons of grazing. These 11 populations will continue to be grazed and monitored for survival for several more years, after which surviving plants will be evaluated for use in the development of a new cultivar for improving forage production and quality on semiarid rangeland (SD00155).

OUTPUTS: Activities: Resources were used to maintain land, equipment, and livestock so they are available and functional for research purposes. Funding for research comes from other sources. Projects that supported research on this study site included SD00197G, SD00155-H, SD00174, SD00213, SD00R216, SD00H224, SD, SD00292-H, and SD00351-H. Additionally, an ongoing study funded by the 4-State Ruminant Consortium was conducted to evaluate beef cow-calf system responses to early weaning and winter feeding systems. Two weaning treatments (August or November) and two winter feeding levels (range grazing with supplement or hay feeding) were applied in a 2 by 2 factorial treatment structure. Early weaning allowed cows to gain body condition in late summer and reduced level of forage utilization. Early weaned calves required less days on feed to reach slaughter, but were lighter at slaughter and therefore had reduced gross income relative to November-weaned calves. Early weaned calves also suffered greater morbidity during the post-weaning period. These included evaluation of range, beef cattle, and sheep management practices. A tour was provided in June for Ag Administrators of the four universities in the 4-State Ruminant Consortium, followed by a 4-State Ruminant Consortium Conference in Rapid City. There was a station field day for the public in November. PARTICIPANTS: K. Olson: PD,PI P. Johnson: PD,PI R. Gates: PD,PI R. Perry: PD,PI A. Smart: PD,PI R. Salverson: PD,PI M. Beutler: PD,PI S.

Impacts
Knowledge has been gained to improve range and livestock management. This knowledge ranges from understanding patterns of forage production on rangelands, to improving estrus synchronization protocols, and evaluating alternative livestock management strategies, such as early weaning and winter feeding programs. Research conducted at the Antelope Range Livestock Research Station is intended to provide information to livestock producers and rangeland managers to allow them to develop economically and environmentally sustainable livestock production systems. Early weaning provides the opportunity to improve cow nutritional status in the fall, thus reducing winter feeding requirements and costs. Early weaning also reduced range forage utilization, further reducing costs per cow, but also potentially sparing limited forage supplies during drought. However, alternative management is needed to ensure postweaning health and performance of early-weaned calves.
