The new revision to the look of the future of dairy per the Journal of Dairy Science.
Philadelphia, USA. April 4, 2018
In the future, the global systems of food production will be subject to a higher pressure by the growth of population, urbanization and climate change.
In the past two years, scientists from the united States, the United Kingdom and Sweden have examined the projections and the current data to identify the ways in which the dairy industry can respond to these challenges to meet the increasing demand for dairy products in the next half-century. A new review published in the Journal of Dairy Science® projects how dairy producers will face these challenges and take advantage of the opportunities in 2067 and beyond.
It is expected that the world population will increase from 7.6 to 10.5 billion people in 2067, while the arable land per capita will decrease by 25 percent. Due to the population growth will be uneven, is also expected to increase the disparity in the arable land per capita. With the increase of the density of population has increased urbanization, which has typically led to a higher personal income and a greater demand for dairy products. It is also expected that climate change will force changes in the location of the dairy production.
In the Northern Hemisphere, where it produces 86 percent of the milk in the world, the production is more exposed to climate change since it is less the effect generated buffer for the oceans on the increase of temperature, which is observed in the Southern Hemisphere. Dairy production will move to areas with water supplies more sustainable and growing seasons are appropriate in response to changes in the climate.
To meet the growing demand by addressing these challenges will require that dairy farms are profitable and sustainable. "Dairy producers in 2067 will satisfy the global needs of essential nutrients through the adoption of technologies and practices that improve the health and longevity of cows, dairy farms profitable and sustainable agriculture"said Jack H. Britt, PhD, professor and dean emeritus associate of the North Carolina State University, Raleigh, North Carolina, USA. UU. The authors predict that dairy producers will adopt ways of managing the microbiomes of the digestive systems of cows and other systems of the body to improve the health and well-being. They also believe that more attention will be given to the management of the epigenome of a cow, which manages the responses of the long-term to the environment.
The dairy industry will increase production and safety by strengthening, modernization and specialization. World trade will be an important factor that will influence the profitability, and dairy farms larger will continue to make greater use of automation to reduce costs. Improvements in genetic selection give rise to lines of dairy cattle that are healthier, produce milk more efficiently and are more resistant to diseases and heat. The authors expect a change of the simple export of surplus production of value-added products tailored to the tastes and habits specific.
«The world is facing a challenge to feed its growing population over the next 50 years, and we predict that the dairy industry will meet this challenge by exploiting the knowledge and technology to develop best dairy cows and dairy farms more productive and sustainable"according to Dr. Britt. «
