Book Description
Three studies were conducted to evaluate: 1) rotationally grazed forage for late-summer stockpiling; 2) effects of lactation on self-fed supplement intake; and 3) influence of cow age on hand-fed supplement intake. For the first study, treatments consisted of non grazed, 2X and 3X grazed. Crude protein of forage grazed 3X was greater (P.10) than non-grazed. Yield of non-grazed forage was greater (P

Book Description
Two studies were conducted to evaluate the influence of supplement composition on intake and digestibility of a low-quality (6% CP), cool-season forage, as well as cow performance. Treatments included a non-supplemented control (CON), corn (approximately 8% CP), corn and urea (LU = corn + 0.09 mg/kg BW urea, approximately 27% CP; HU = corn + 0.17 mg/kg BW urea, approximately 43% CP) and a positive control of SBM (approximately 51% CP). In Experiment 1, 5 ruminally cannulated Angus x Hereford steers (560 ± 79 kg of BW) were used in an incomplete 5 x 4 Latin square with four 28-d periods to compare the effects of urea addition to a corn-based supplement on forage intake, digestibility and ruminal fermentation characteristics. Forage intake and digestibility were not influence by supplementation (P 0.10); however, intake was greater for SBM than HU (P = 0.01). Ruminal NH3-N increased with supplementation (P 0.01), increased linearly with urea inclusion (P 0.01) and was greater for HU than SBM (P 0.01), However, ruminal NH3-N for non-supplemented steers was 1.61 mM, within the range believed to support optimal growth of rumen microbes in vivo, suggesting that ruminally available-N was not limiting forage utilization. Total volatile fatty acid concentration was not influenced by supplement composition (P 0.10). In Experiment 2, 80 late gestation (approximately 190 d pregnant) Angus x Hereford cows (507 ± 10 kg) were stratified by age, BCS, and BW and randomly allotted to the treatments described in Experiment 1 (20 pens; 4 cows/pen; 4 pens/treatment). Cow BW and BCS change were improved with supplementation (P

Book Description
Management Strategies for Sustainable Cattle Production in Southern Pastures is a practical resource for scientists, students, and stakeholders who want to understand the relationships between soil-plant interactions and pasture management strategies, and the resultant performance of cow-calf and stocker cattle. This book illustrates the importance of matching cattle breed types and plant hardiness zones to optimize cattle production from forages and pastures. It explains the biologic and economic implications of grazing management decisions made to improve sustainability of pastures and cattle production while being compliant with present and future environmental concerns and cattle welfare programs. - Documents the effects of cattle grazing on greenhouse gas emissions and carbon footprints - Discusses strategies to enhance soil fertility, soil health, and nutrient cycling in pastures - Provides information on the use of stocking rates, stocking strategies and grazing systems to optimize cow-calf production of weaned calves and stockers. - Presents innovations in cattle supplementation and watering systems to minimize negative impacts on water and soil health - Includes methods for weed control to maintain pasture condition and ecosystem stability - Describes management strategies to integrate cattle operations with wildlife sustainability

Book Description
The health and profitability of grass-based livestock begins with the food they eat. In Managing Pasture, author Dale Strickler guides farmers and ranchers through the practical and ideological considerations behind caring for the land as a key part of running a successful grass-based operation, from the profitability of replacing expensive grain feed with nutrient-rich native grasses to the benefits of ecologically-minded land management. In-depth examinations of the biology and benefits of grazing plants and different grazing strategies accompany detailed plans for paddock and fencing set-ups, livestock watering, and effective methods for dealing with common pasture problems throughout the seasons, from mud to drought. For readers invested in pasture improvement strategies that offer environmental benefits beyond better meat and dairy, including carbon sequestration, erosion prevention, increased pollinator resources and wildlife habitat, and improved water quality, Managing Pasture is an approachable, accessible guide to creating and caring for the grassland that feeds animals and future generations.

Book Description
Two studies investigated methods of decreasing feed costs of cow-calf operations. In the first study, two experiments were conducted to determine the difference in grazed forage intake of beef cows of known residual feed intake (RFI) rank. Low RFI (highly efficient) cows had a 21% lower average numerical forage intake (P = 0.23) than high RFI cows (lowly efficient) during mid to late gestation in Experiment. 1. In Experiment 2, an 11% numerical difference in forage intake (P = 0.12) was observed between low and high RFI cows in late lactation, while in both experiments RFI groups had similar body weight (BW) and body condition score (BCS) change. Further research is necessary to confirm these differences due to low numbers used in this study. A second 2-year study compared performance differences between spring-calving crossbred beef cows wintered on one of three treatments: grass hay only, grass hay with grain supplementation, or non-endophyte infected stockpiled tall fescue (STF) pasture. Cows grazing STF ended the trial with higher BW and BCS than cows fed hay only in both years and cows fed hay with supplement in year 1. Differences in performance did not extend past winter grazing, and calves born had similar birth and weaning weights among treatments. Grazing STF is a viable option for wintering spring-calving beef cows, and because typical grass hay is of lower quality than STF, cows fed hay require supplementation to achieve similar performance to that observed while grazing STF.

Book Description
Forages: The Science of Grassland Agriculture, 7th Edition, Volume II will extensively evaluate the current knowledge and information on forage agriculture. Chapters written by leading researchers and authorities in grassland agriculture are aggregated under section themes, each one representing a major topic within grassland science and agriculture. This 7th edition will include two new additional chapters covering all aspects of forage physiology in three separate chapters, instead of one in previous editions. Chapters will be updated throughout to include new information that has developed since the last edition. This new edition of the classic reference serves as a comprehensive supplement to An Introduction to Grassland Agriculture, Volume I.

Book Description
Forages, Volume I, Seventh Edition is the most comprehensive text available for teachers of undergraduate Forages courses. This edition will provide students with a good balance of scientific principles, to aid in integrating the concepts they learn, and practical information on forage identification, plant characteristics, management, and utilization that can be used by forage management practitioners. Grassland ecosystems are extremely complex, including the plant/animal interface as well as the soil/climate/forage interface and the text must support understanding and integration of all of these considerations. The coverage of the science behind the plant characteristics and responses make the book applicable in many parts of the world, while other region-specific management information relates mainly to North America. This edition has been updated to address emerging areas of study, including the use of forage plants as bioenergy crops. The editors also address the renewed national interest in environmental issues such as water quality, global climate change and eutrophication in the Gulf. This edition also addresses the role of forages for wildlife habitat and food sources, another area of increased interest in recent years. These revisions respond to the generational change taking place among forage scientists and teachers in recent years.
