In general the US is seeing more precipitation and the timing and intensity of precipitation is also changing. While global temperatures are increasing, it is the variability and intensity of temperatures that are of greatest consequence to animal agriculture.
Impact of climate change on livestock reproduction and its ameliorative measuresDrSapunii Hanah
Climate directly or indirectly has a great impact on livestock production and reproduction such as estrus cycle, follicular growth, fertility, semen production etc. However, there is always a way to tackle the problem by implementing scientific housing system, nutritional intervention etc
Presentation by Bernard Bett at the 14th conference of the International Society for Veterinary Epidemiology and Economics (ISVEE), Merida, Yucatan, Mexico, 3-7 November 2015.
Presentation by Mario Herrero, Philip Thornton and Iain Wright to Workshop on climate change vulnerability and adaptation in the livestock sector, Kathmandu, Nepal, 28-29 October 2010.
This Thematic Paper is part of a Toolkit for Project Design (Livestock Thematic Papers: Tools for Project Design) which reflects IFAD’s commitment to developing a sustainable livestock sector in which poor farmers and herders might have higher incomes, and better access to assets, services, technologies and markets.
The paper indents to be a practical tool for development practitioners, project designers and policymakers to define appropriate livestock development interventions. It also provides recommendations on critical issues for rural development and also possible responses and actions to encourage the socio-economic empowerment of poor livestock keepers.

Animal Disease Control Programs in India.pptBhoj Raj Singh
India is a hyperendemic country for many animal diseases and zoonotic diseases. Every year billions of rupees are spent on disease control, surveillance, monitoring, and vaccination against vaccine-preventable diseases. However, due to the failure of most animal disease control programs for one or other reasons India directly losses about 20 and 25 thousand crores annually due to endemicity of FMD & brucellosis, respectively. The presentation describes the pros and cons of different ongoing disease control programs going on in India.
Farm animals have well known zones of thermal comfort (ZTC). The range of ZTC is primarily dependent on the species, the physiological status of the animals, the relative humidity and velocity of ambient air, and the degree of solar radiation. Economic losses are incurred by the U.S. livestock industries because farm animals are raised in locations and/or seasons where temperature conditions venture outside the ZTC. The objective of this presentation is to provide current estimates of the economic losses sustained by major U.S. livestock industries from thermal stress and to outline future challenges as animal productivity is improved. Species (production) considered are: chicken (meat), chicken (eggs), turkey (meat), cattle (meat), cattle (milk), and pig (meat).

Vector borne infectious diseases in the face of climate changeSEJOJO PHAAROE
To understand how climate might affect the incidence of vector-borne diseases, one must first examine the life cycles of the diseases and the environmental parameters associated with each stage
A vector-borne disease is one in which the pathogenic microorganism is transmitted from an infected individual to another individual by an arthropod or other agent, sometimes with other animals serving as intermediary hosts.
The transmission depends upon the attributes and requirements of at least three different living organisms:
- the pathologic agent,
-the vector, and the human host.
intermediary hosts such as domesticated and/or wild animals often serve as a reservoir for the pathogen until susceptible human populations are exposed
We recommend proactive planning
more surveillance of direct impacts, such as changes in the reproduction rate of the vector or the agent, the biting frequency of the vector, and the amount of time the host is exposed to the vector due to changes in temperature, rainfall, humidity, or storm patterns.
Even less information is available to evaluate the impacts of societal and individual activities on the transmission of vector-borne diseases.
Changes in hydrology, agriculture, forestry, and infrastructure in response to global warming may also indirectly affect the interrelationship among the disease agent, vectors, and hosts
The interconnections between human, animal and environmental healthUniversity of Calgary
One Health is an initiative that looks at how people, animals and the environment interact, and the health impacts that each has on the others. Researcher Dr. Baljit Singh provides a deeper insight into how One Health could improve our understanding of complex problems such as food safety, water safety, infection and disease transmission through a cross-disciplinary approach.
Co-presenter Dr. Susan Cork looks at three different case studies on vector borne diseases in Canada to illustrate the need to take a One Health approach in the face of climate change and other factors affecting in how diseases are distributed.

Climate change - influence on animal health and production
1. Climate change –
influence on animal health and production

2. Different problems are
seen for different:
• Species and breeds
• Regions
• Husbandry regimes
Climate change
affect animals
3. • Immunosuppression
• Production↓ growth, milk, egg,..
• Reproduction↓ sperm quality, embryo survival, heat symptoms
Heat sensitive animals e.g.
• Aquatic animals mostly has a narrow temperature window
• Swine and poultry can not sweat
• Full-fatted and winter coated outdoor cattle in the autumn
• High yielding animals
Heat stress cause health effects
4. The high yielding dairy cow -
an example of a heat sensitive animal
• Already high metabolism
• Effects are seen on
– body temperature
– reproduction
– milk production
– animal welfare
• Milk production is generally
“well recorded”

Eckersten, Djurle, Albihn, et al. 2015, SLU Report
6. Adaptation to increasing temperature
– to reduce the negative effects
•Possibilities to change behavior
•Grassing nighttime instead of daytime
•Supplementary cooling, ventilation
•Bedding material
•Bathing
•Adjustment of feed/feeding routines
•Adjustment of stables, transportation,..

Semi-domesticated reindeer are facing
a new situation concerning climate
change and ecosystem changes
8. Reindeer herding
Free-grazing, wide areas, adapted to harsh ecosystems
Highly specialized animals, sensitive to environmental perturbations
The present grazing area depend on season and weather.
By tradition high flexibility, today reduced access to alternative areas
Migration or transport
Influencing northern ecosystems - feeding and migration patterns
Important for indigenous people as Sami and Nenets
From nomadism to modern pastoralism

9. CC ads on another stressor on a
heavily burdened animal production…..
Repeated thawing/freezing events causes icing on the ground
Teethes may be seriously damaged while RD try to reach their forage
Has to be fenced for supplementary feeding
This also causes increased morbidity and mortality due to;
crowding and increases general stress load
changed diet (e.g. tree-hanging lichen to hay and pellets)
opportunistic infections (no harm to the host during optimal conditions)
Photos Ulrika Rockström, Gård och Djurhälsan
10. Secondary effects of ecosystem
changes
• The thawing tundra may
cause outbreaks of anthrax
(Bacillus anthracis) in Russia
• Possible air-exposition of
buried carcasses from earlier
large epizootics of “Sibirski”
• 13000 burial grounds, more
than half in permafrost
(Revich & Podolnaya, 2011; Glob Health Action)
Photo Ulrika Rockström,
Gård och Djurhälsan
11. • Shortage of water may cause wildlife density to increase in
the neighborhood of water sources
• The spread of infectious diseases may be enhanced, both
within and between species
• Animal production e.g. milk, needs much water
• Contamination of water sources due to increased events of
surface run-off and flooding
CC affects both water availability and quality
12. • Increased risk: Heavy rain, delayed
harvest, low dry matter content at harvest
• Fungus (Fusarium spp produce
Deoxynivalenol, Vomitoxin and Zearalenon)
in straw and seed
• Pigs are sensitive and may show
decreased growth rate and fertility
CC may cause increased problems
with mycotoxins in feed
13. Insects
Annoyance – rest and feed less
Blood suckling - anaemia, toxins, death
As vectors - transmitt diseases
14. Insect larva may eat on live animals
(blowfly strike, cutaneous myiasis)
Risk dependent on:
Temperature
Humidity
Length on season
Density of insect populations
Breed, age, flock size
Worm burden - faecal soiling
Adaptation by:
Deworming
Insecticide use
Fly traps
(Mulesing!!)
Earlier sheering of
ewes in the spring
16. Climate sensitive infections (CSI)
Here defined as: Dependent on the
natural environment for their spread
or persistence, e.g. transmitted to a
new host or species by arthropod
vectors, water or soil, or they use
wildlife as a reservoir.
CC may impact the epidemiology,
geographical distribution,
seasonality, prevalence, … of CSI
BUT - many other anthropogenic
environmental factors may also
influence CSIOIE, 2008
(World Organisation of Animal Healt)
18. Vectorborne diseases (VBD)
Dependent on the abundance and density of
arthropod vectors and other animals
used to feed on, as intermediate hosts or
as reservoir animals
CC may cause e.g. increased winter
survival and more suitable habitats for
vectors and other animals
A competent arthropod vector can carry,
reproduce and transmit the pathogen,
this is dependent on the ambient
temperature and many other
environmental factors
VBD mostly zoonotic infections
humans - animals
19. Borreliosis/Lyme diseases
• Tick has changed its distribution to
higher latitudes (Lindgren et al.,
2000)
• Influence of temp., humidity,
vegetation
• Rodents are reservoir species
• Deer, humans and others
are mostly ”dead end host”
20. A surprisingly quick spread of a VBD
Schmallenberg virus (ortobunya)
affect ruminants
Infection during first half of gestation
causes dead or malformed
offspring
In the end of 2011 in central Europe
Swedish survey 2012 of farm based
milk containers (Chenais et al. 2013)
May -1/ 723 farms pos.
Nov – 521/ 723 (72%) pos.
Virus detected also in
midges (Culicoides spp.)
aborted lambs and calves,
In wildlife as roedeer and moose
21. Bluetongue - an epizootic among ruminants
• From Africa, 2006 to several EC countries, 2008 to Swe
•Infected midgets (Cullicoides) windspread from Denmark
•Hot summer and dense populations
of midgets caused spread in Swe
• Costly disease control, vaccination
22. Identification of ”epidemiological hotspots” -
to predict VBD outbreaks
Decrease the cost for vector
surveillance
Increase the success of handling of an
outbreak
A process-based model includes
temp, precipitation, vector
abundance, biology/distribution,
traits of pathogen
Prediction models – aim to model the
potential transmission
intensity of a pathogen
Good models need good
data, but a model will
never be perfect

Animal welfare aspects
24. • Environmental and ecosystem changes
affects animals in many ways as heat-
stress, infectious diseases and
availability of feed and water
• CC starts complex and dynamic
interaction between ecosystems, vectors,
pathogens, animals and humans
• For vector-borne diseases, changes are
ongoing in geographical distribution,
seasonality, prevalence,…
• Wildlife may be seriously affected
themselves but also act as a disease
regulators for domestic animals and
humans
• Lessons learned from other regions - but
adaptation needed to local conditions
• Healthy animals produce more
Conclusions
25. Climate change adaptation –
to avoid that surprises turn into crises
As more we know as better we can adapt
