aware of the impact of sustainability on the dairy sector.
 climate change,
 animal welfare,
 biodiversity &
 soil fertility.

The dairy sector is continually finding new ways
to improve sustainability:
• human food waste & animal manure as an effective fertilizer,
• along with establishing feed efficiencies,
• farmers are ensuring an improvement in yield&
• decreasing their environmental footprint.
 increase energy efficiencies,
 reduce greenhouse gas emissions,
 reduce water wastage,
 save energy, and
 lower operating costs for dairy farms.

“Dairy Net Zero”
This means that the day aims-
The theme also marks the need to improve
waste management in the dairy sector in
order to make the industry more sustainable.
Sustainable Dairy Farming Strategy

Working towards sustainable dairy production

Dairy farms

greenhouse gasses emissions……

Improving soil quality focuses on…..
optimal crop yields combined with adding to soil ecosystem functions
such as
 water regulation,
 nutrient cycling and
 soil microbial & plant biodiversity.
Soil quality & nutrients
Nutrient application will be adapted to minimize nutrient losses
such as nitrogen & phosphorus to water and air.

Land use for growing dairy cattle feed
will impact local and global
biodiversity.

Biodiversity
Developing best practices that contribute to biodiversity is an emerging topic in dairy research.

 facilitate growth of crops,
 drinking water for animals and
 use for cleaning
Water can have many roles on the farm:
Water quality & quantity
Minimising the impact of the farm on the quality of surface & ground water is the
first sustainable objective
efficient use of water, both for crop and for milk production.
use of fertilizer, manure, biocides & other types of water
contamination.
connected to the

Animal welfare & health
Creating conditions to enable normal patterns of
animal behaviour by……
adjustments of housing & application of grazing will
have a positive impact on welfare and health.
FMD, mastitis & heat stress are important issues that require further improvement to increase animal welfare.
The introduction of measurements on animals to monitor animal welfare is an
important field of research to better understand welfare and discomfort.

This would contribute to the world food security. The challenge for the dairy sector is
to reconsider the position of the dairy cow in a circular food system.
Circular food production
The aim of a circular food system is to optimize the use
of available biomass resources in the world.
One of the goals in this circular approach is to avoid the use of
human-edible biomass (such as grains and pulses) as food source for animals.
Future feed rations should focus more on residuals from plant production &
by products from the food industry.

Incorporating sustainability themes including the optimal use of land
resources are important aspects to build strong international dairy chains
that contribute to economic growth.
Rural livelihoods/
Farm Economy
The dairy sector contributes to the economic viability &
resilience of many rural communities &
to supplying nutritious food in many countries.
Building stronger dairy chains responding to market needs & securing safe
& nutritious dairy foods are crucial goals in dairy development.

Economy of Bangladesh based primarily on agriculture...
Livestock (dairy) an essential component of the
rural economy & the livelihood of the subsistence farmers
More than 60% of the families involved in dairying
consist of small & marginal farmers….
About 84.4% of its population is living in rural areas
Dairying plays an important role in rural economy & poverty alleviation….
Dairying in Bangladesh

Open the opportunity for dairy farmers to exploit the rising demand on milk &
milk products at national as well as global dairy markets.
Dairying in Bangladesh transforming from traditional subsistence to more market-oriented &
enterprise-driven approach in the dairy production system (Uddin et al., 2020)

Mineral mobilization

Good for Skin
Milk contains many vitamins
& nutrients,helps to keep our
skin supple, soft and
glowing.

Relief Stress
Milk contains many vitamins &
minerals that work as a stress reliever.
Drinking milk reduce stress in our body.

Probiotics and bioactive compounds
 Probiotics play a role in inhibiting Heliobacter
pylori infections which cause ulcers
Live bacteria that provide a
health benefit
Fermented milk products
(yoghut, yoghurt drinks)

can act through diverse mechanisms, including modulation of
immune function, production of antimicrobial compounds and
organic acids, improvement of gut barrier integrity, formation
of enzymes, and interaction with resident microbiota
Good source of probiotic

Probiotics and bioactive compounds

Milk & Cancer
 High fat dairy foods & CLA may reduce the risk of colorectal
cancer
 Butyric & Caprylic acid of milk fat has been reported to delay
tumour growth
 Ca, vit-D, CLA, sphingomyelin, whey proteins & some fatty
acids of milk protects against cancer
 Ca & Vit.-D may reduce the risk of colon and breast cancer in
human

Milk & dental carries
Milk is the abundant source of Ca and phosphorus,
which helps in mineralization process and also
maintain buffering effect on mouth pH that helps to
prevents dental carries

Milk & Milk Products and Immunity
Immunity

 Maintaining strong immunity is the most effective approach to fight
against COVID-19 virus and for managing the continuous risk of viral
infection.
Milk and Milk Products, Immunity and COVID-19

Vitamin (A, C,
D, E, and B
complex)
Mineral (zinc
and selenium),
Water
Anti-oxidants
Certain essential
fatty acids
Bioactive
components

Vitamin D protects respiratory tract by preserving tight junctions, killing
enveloped viruses and reducing the risk of a cytokine storm leading to
pneumonia (Muscogiuri et. al., 2020).

Vitamin A comprises a group of fat soluble compounds (including retinol,
retinoic acid, and β-carotene) that play an essential role in the immune
function (Huang et. al., 2018).

Milk and milk products also contains some immune boosting
compound like lactoferrin, immunoglobulin, lactalbumin, glycopeptides,
amino acids and so on.

Lactoferrin is a broad-spectrum antiviral agent, and has immunomodulatory
and anti-inflammatory characteristics that can positively modify host
responses to the novel severe acute respiratory syndrome coronavirus 2
(SARS-CoV-2) that causes COVID-19 (Chen et. al., 2020).
Lactoferrin

Antimicrobial components of milk like immunoglobulins
provide passive immunity against enteric and respiratory
bacteria and viruses.
Prevent gastrointestinal tract infections,
upper respiratory tract infections
Plays important roles in phagocytosis
clearance of pathogens

Lactalbumin is also readily digestible and is anticarcinogenic, and affects
the immune response by regulating the intestinal flora and stimulating
glutathione synthesis, thereby improving immune function.

In fact, research strongly supports this claim, as many studies have found
that whey protein may increase levels of glutathione and, therefore,
reduce oxidative stress.
Glutathione is an important component of immune system as the balance or
imbalance of glutathione levels are known to significantly affect lymphocyte
function.
Glutathione

Milk fat contains different types of fatty acids where monounsaturated and
polyunsaturated fatty acids are known for their favorable immune-
modulatory action.
Omega-3 fatty acids support the immune system by activating cells
from both the innate and the adaptive immune systems
Omega-6 monounsaturated fatty acids have antioxidant, antimicrobial,
and antiviral effects

Fermented milk products like dahi, yogurt, cheese etc. are excellent
source of probiotics.
Probiotics are defined as “live microorganisms that, when administered in
adequate amounts, confer a health benefit on the host.

Play a role in the control
oweight gain as well as
some of the most
important risk factors for
COVID-19 complications
Important
modulators of the
immune system
Play a role in the
control of
hypertension,
diabetes,
Reduce the severity of
respiratory infections,
by increasing of IgA in
the bronchial mucosa

Milk and dairy products cannot prevent and cure this virus completely.
Milk and milk products can be a potential option to develop & maintain sound nutritional
status as well as build up immunity against COVID- 19 virus infection.
But healthy diet like milk and dairy products can also decrease the risk of, or help to
control hypertension, diabetes, obesity, and muscle atrophy, which are all considered risk
factors for COVID-19 complications.
