A doctoral research assistant position is available at the University of Wisconsin, Madison, USA for a highly motivated student seeking PhD training in Dairy Science beginning in Fall 2017. The successful applicant will conduct research on dairy cow protein nutrition and methods for improving and evaluating the efficiency of nitrogen utilization.
Excess crude protein (CP) in the diets of dairy cows is excreted in the urine as urinary urea nitrogen (UUN). This source of N reduces the environmental sustainability of dairy farms because it can contribute to atmospheric ammonia and nitrous oxide emission and to nitrate contamination of waters. Avoiding excess CP in the ration of dairy cows may contribute to the economic and environmental sustainability of the dairy industry if milk production is maintained.
Applicants must have earned a MS degree (or equivalent) in a relevant field and a record of peer- reviewed publications.
Applications by 1 March 2017. For more information and how to apply click here
The Paddy Rice Research Group’s Sub-America’s division met on 13-15 July this year in Stuttgart, Arkansas, USA. The meeting was attended by 10 GRA Member countries: Argentina, Brazil, Canada, Chile, Colombia, Indonesia, Japan, New Zealand, Uruguay and USA, and a meeting report will soon be available. The presentations for the meeting are now available in the Members’ Area of the website.
The college of Agricultural and Environmental Science, UC Davis has posted an interesting article on “Facts and Fiction on Livestock and Climate Change” by Frank Mitloehner, Professor UC Davis.
Professor Mitloehner shows the proportion of US total GHG emissions from livestock production (4.2%) in comparison with emissions from other sectors. Suggesting that a direct comparison between emissions from the US livestock sector and the energy (31%) and transport sectors (27%) brings into perspective the amount of difference that can be made by reducing livestock emissions.
Of course that is not to suggest that the livestock sector is not required to play its part in reducing emissions. The article shares impressive statistics from the US beef and dairy sectors showing how production from both sectors has increased over the last 50-65 years, although the total number of livestock has decreased.
- 1950: 22 million dairy cows produced 117 million tons milk
- 2015: 9 million dairy cows produced 209 million tons of milk. (Fifty-nine percent fewer cows produced 79 percent more milk than they did in 1950.)
- 1970: 140 million head of cattle produced 24 million tons of beef
- 2015: 90 million (36 percent fewer) head of cattle produce 24 million tons of beef
The full article can be read on the UC Davis website.
For information on some of the management practices that the US are using to continue reducing emissions from their dairy sector in particular see the case studies developed by the Livestock Research Group.
Faculty from Penn State’s Departments of Animal Science, Veterinary and Biomedical Sciences, Plant Sciences, and Agricultural Economics are developing the world’s first Dairy Production and Management MOOC (Massive Open Online Course). The course is designed to deliver fundamental knowledge and best practices related to sustainable dairy production systems in their broadest sense. Participants will gain a broad and comprehensive understanding of all aspects of dairy management including genetics, nutrition, reproduction, animal health, milk hygiene, farm economics, and sustainability of dairy production systems. There’s something in this course for everyone, whether you are just looking for the basics or have years of experience in the dairy industry. The course is launching March 7th, 2016. For more information and to register please visit the course’s website: https://www.coursera.org/
The USDA has officially released a report that provides scientific methods for quantifying the changes in greenhouse gas (GHG) emissions and carbon storage from various land management and conservation activities in the USA.
The report, ‘Quantifying Greenhouse Gas Fluxes in Agriculture and Forestry: Methods for Entity-Scale Inventory,’ will help USDA evaluate current and future GHG conservation programs, as well as develop new tools and update existing ones to help farmers, ranchers and forest landowners participate in emerging carbon markets.
