The objective was to determine if low- or high-residual feed intake (LRFI or HRFI, n = 24 for each) Hereford × Angus cows on continuously or rotationally grazed rangeland altered their grazing behavior when provided a protein supplement in late autumn. Treatments included continuously grazed, control (CCON, n = 12); continuously grazed, supplemented (CTRT, n = 12); rotationally grazed, control (RCON, n = 12); and rotationally grazed, supplemented pastures (RTRT, n = 12). Cows in each treatment had grazing time (GT), resting time (RT), and walking time (WLK) measured for 2 years with accelerometers. Bite rate (BR) was also measured. Time distributions of GT and RT differed by year (p < 0.05), being influenced by colder temperatures in 2016. Cattle in 2016 spent more time grazing during early morning and late evening (p < 0.05) and rested more during the day (p < 0.05). In 2017, cattle in the CCON treatment walked more (p < 0.05) during early morning time periods than did the CTRT cattle, indicative of search grazing. All supplemented cattle had greater BR (p < 0.05) than control cattle in 2017. Cattle with increased nutritional demands alter grazing behavior in a compensatory fashion when grazing late-season rangelands.

The Impact

Abstract Developing alternative parasite management strategies is critical as anthelmintic resistance continues to be a global concern in small ruminant grazing operations. Converting cropland to pastureland may serve as one strategy to develop parasite free pasture, thus reducing the need for anthelmintic treatment. The objective of this study was to evaluate the impact of pasture contamination with gastrointestinal parasites and protein supplementation on the mitigation of parasitic infection in grazing lambs. We hypothesized that lambs grazing on newly established pasture (clean) without supplementation would perform similarly to those lambs grazing on permanent sheep pasture (infected) provided supplementation. A total of 96, 60-day old lambs (30 kg ± 4.0 kg), were randomly assigned to one of four treatments: 1) clean pasture without supplementation (CN); 2) clean pasture with supplementation (CS); 3) infected pasture without supplementation (IN); and 4) infected pasture with supplementation (IS). Packed cell volume (PCV) and fecal egg counts (FEC) were monitored biweekly. Data were analyzed using PROC MIXED in SAS. Based upon fecal egg fluorescence, 66% of the fluoresced eggs in the mixed infection population were Haemonchus contortus. There was a pasture × supplementation × day effect for PCV in that CN lambs had a greater PCV than IS lambs on days 28, 42, 56, and 70 (P &lt; 0.0001). However, on days 98 and 112, IS lambs had a greater PCV than CN lambs (P &lt; 0.001). In addition, there was a pasture × supplementation × day effect for FEC such that IS lambs demonstrated a greater FEC over time from day 28 to day 112 compared to CN lambs (P &lt; 0.001). Offering supplemental protein to lambs grazing pastures contaminated with gastrointestinal parasites may help lambs cope with a heavy parasite burden. Therefore, developing additional management strategies will be key in reducing the future use of anthelmintics.

Hansen, M. J., Owens, V. N., Beck, D. and Sexton, P. 2013. Suitability of cover crop monocultures for late-season forage in South Dakota. Can. J. Plant Sci. 93: 589–597. Cover crops provide many agronomic benefits and can produce large amounts of forage that is suitable for grazing. The objectives of this study were to determine (1) suitable cover crop forages based on yield and nutrient values; and (2) changes in feed value and yield of these crops through the late fall. Five cover crop monocultures consisting of lentil (Lens culinaris Medikus), cowpea (Vigna unguiculata L.), foxtail millet (Setaria italica L.), oats (Avena sativa L.), forage radish (Raphanus sativus L.), and a mixture of these crops were planted after winter wheat (Triticum aestivum L.) harvest in 2010 and 2011 in central and southeastern South Dakota. Forage data were collected on approximately Oct. 01, Nov. 01, and Dec. 01 each year. Yields increased after the first harvest date at both sites, both years. Oats, radish, and the cover crop mixture all yielded >4000 kg of dry matter per hectare on the second harvest date in 2011 in central South Dakota and radish and oats yielded >4000 kg ha−1 in southeastern South Dakota on the second and third harvest dates, respectively. Forage quality tended to decrease after each harvest date. Radish in central South Dakota in 2010 had the highest protein values for the study (194–313 g kg−1) whereas oats in southeastern South Dakota had the lowest protein concentrations (63–108 g kg−1), both years. All cover crops except cowpea were viable forages through the late fall when they had good establishment with the potential need for protein supplementation with oats, foxtail millet, and the cover crop mixture, depending on animal requirements.

Mixed perennial ryegrass and white clover swards are often used as the basis of upland sheep grazing systems. This study’s objective was to examine voluntary herbage intake and diet selection in 30 lactating Scottish-Blackface ewes grazing mixed perennial ryegrass (PRG) and white clover (WC) swards supplemented with or without protein. The work was part of a wider study of nutrition and parasitology in organic sheep systems.

Reducing Costs

Florida has 915,000 beef cows and 125,000 replacement heifers (USDA, 2016). Developing these heifers so that they can become productive females in the cow herd is a tremendous investment in a cow/calf operation, an investment that takes several years to make a return. The good news is that there are options to develop heifers on forage-based programs with the possibility of reducing costs while simultaneously meeting performance targets required by the beef industry. Mild winters in Florida allows utilization of cool-season forages that can significantly enhance the performance of grazing heifers. During the warm-season, integration of forage legumes into grazing systems will provide additional nutrients to meet the performance required to develop a replacement heifer to become pregnant and enter the mature cow herd. In this document, we will propose a model for replacement heifer development, based on forage research performed in trials at the NFREC Marianna.
