Policy Measures For Extensive Farming Systems In Southwest Norway, Lief Jarle Asheim, Pål Thorvaldsen, Odd J. Øvreås Apr 2020

Policy Measures For Extensive Farming Systems In Southwest Norway, Lief Jarle Asheim, Pål Thorvaldsen, Odd J. Øvreås

IGC Proceedings (1977-2023)

The open landscapes produced over centuries by farming in southwest Norway are threatened by agricultural abandonment, raising public concern for maintenance of the species rich and valuable coastal grasslands. A study in two municipalities revealed that semi-natural grasslands, traditionally grazed in spring and fall and mowed in-between, are most affected. Two linear programming models, one for part time sheep farms and one for larger mixed dairy and meat farms, were developed to study measures for stimulating production, in particular effects on grazing and land utilization of altering support between leys, farm pasture, and grazing animals. Yields and fertilization level in …


Manipulation Of The Spatial Grazing Behaviour Of Livestock In Extensive Grassland Systems, Derek W. Bailey, Mitch B. Stephenson, Milton G. Thomas, Juan F. Medrano, Gonzalo Rincon Dec 2019

Manipulation Of The Spatial Grazing Behaviour Of Livestock In Extensive Grassland Systems, Derek W. Bailey, Mitch B. Stephenson, Milton G. Thomas, Juan F. Medrano, Gonzalo Rincon

IGC Proceedings (1977-2023)

Spatial behaviour of livestock is a critical factor in grassland management. Recent and ongoing research suggests that new approaches can be used to manipulate where cattle graze. The combination of strategic supplement placement and low-stress herding can be used to target cattle grazing and potentially may be useful for managing fine fuels. A phenotype to genotype association study of cattle spatial behavior suggests that use of rugged terrain and areas far from water is inherited. Although more research is needed, selection for animals specifically adapted for mountainous terrain or extensive paddocks may be an alternative for managing grasslands in the …


Effects Of Irrigation And Season On Performance Of Grazed Pastures Of Brachiaria Brizantha Cv. Mg5, Rita De C. R. Carvalho, Wellington W. Rocha, Bruno S. Pires, César T. Piza, Luziney D. Silva, Paulo R. V. Leite, Eliel A. Ferreira Dec 2019

Effects Of Irrigation And Season On Performance Of Grazed Pastures Of Brachiaria Brizantha Cv. Mg5, Rita De C. R. Carvalho, Wellington W. Rocha, Bruno S. Pires, César T. Piza, Luziney D. Silva, Paulo R. V. Leite, Eliel A. Ferreira

IGC Proceedings (1977-2023)

In Brazil, livestock production is based primarily on systems with continuously grazed natural or cultivated pastures (FAO 2009). Intensifying animal breeding, handling and knowledge strategies is necessary to obtain improvements in production indices for economically feasible and sustainable grazing systems (Cedeño et al. 2003). Beef cattle breeding on irrigated pasture, like all forms of intensive grazing, requires the use of forage species with high potential for production and quality, and Brachiaria brizantha cv. MG5 is considered a good option. This study aimed to evaluate the effects of irrigation on the performance of B. brizantha cv. MG5 grazed rotationally by …


Mob Vs. Rotational Grazing: Impact On Forage Use And Artemisia Absinthium, Heidi Reed, Alexander Smart, David E. Clay, Michelle Ohrtman, Sharon A. Clay Jan 2018

Mob Vs. Rotational Grazing: Impact On Forage Use And Artemisia Absinthium, Heidi Reed, Alexander Smart, David E. Clay, Michelle Ohrtman, Sharon A. Clay

Short duration (≤24 h), high stocking density grazing systems (e.g., mob grazing) mimics historic prairie grazing patterns of American bison (Bison bison), and should minimize selective grazing. We compared mob [125 cow-calf pairs on either 0.65 ha for 12 h; or 1.3 ha for 24 h] vs. rotational [25 cow-calf pairs on 8.1 ha for 20 days starting in mid-May with or without 2,4-D application prior to grazing; and 15 days starting mid-April (no herbicide)] grazing systems based on forage utilization and impact to Artemisia absinthium (absinth wormwood) in a tall grass pasture of Eastern South Dakota. Grass …
