GUT HEALTH PROMOTES ANIMAL WELFARE
to this interaction as "nutribiosis."
"This balance is fragile and can be
disturbed by animal welfare practices,
as well as a wide range of external factors such as climate, environment or
microbial challenges," he says.
Mateboer suggests the right combination of additives and nutrients
help achieve this balance.
additive solutions used to support
gut health include organic acids,
medium-chain fatty acids, essential
oils, probiotics, prebiotics, minerals
and beta glucans.
Feed additives solutions
Here are several examples of
how feed additives can be utilized
70 PERCENT OF AN animal's
immunity is concentrated in the gut.
"Optimal gastrointestinal functionality is of the utmost importance
because it positively influences
animal health, performance, environment and welfare by preventing
loss in feed efficiency and the use of
antibiotics," Panciroli says, noting
that for this reason the use of feed
supplements, functional foods and
ingredients have been on the rise.
According to Marsteller, feed
to support animal welfare while improving gut health:
■ Protease + adaptive direct-fed microbial: This combination works
to improve gut barrier strength
through tight junctions, enhance
protein digestibility, amino acid
utilization and fiber-bound nutrient
release - as well as positively affect microbiome function. Studies
show improved liveability, average
daily gain and feed conversion ratio in grower/finisher pigs.
■ Phytase: Phytate binds protein in
the upper GIT, making it unavailable to the animal, resulting in increased acid and pepsin production
in the stomach. As the stomach
empties, increased acidity damages the gut absorptive surface and
requires more buffering through
the release of sodium bicarbonate,
negatively effecting gut function.
Phytase breaks it down before it
binds to the protein, avoiding the
anti-nutritive effects of phytate and
improving nutrient uptake for a
better functioning gut.
Animals are shown to
overcome heat stress and increase
performance during the summer
with the use of live yeast. The
live yeast, which also improves
fiber digestibility, promotes the
production of fibriolitic bacteria,
influencing the production of
short-chain fatty acids.
Establishing, maintaining gut health
Mateboer suggests nutritionists address three factors to maintain a favorable "nutribiotic" state:
■■ Nutrition: Ensure the animal has all the nutrients it
needs to reach its full potential. Limit the amount
of undigested nutrients or control the types of
undigested nutrients that reach the terminal ileum
as not to provide substrates for the non-beneficial
bacterial populations to feed and thrive on.
under control to avoid the occurrence of subclinical and clinical disease challenges that
reduce overall performance and profitability.
■■Gut + immunity function: A well-developed
gut structure and high-functioning immune
system are vital to allow animals to maximize
nutrient absorption and deal with bacterial, viral or environmental challenges. Any immune
■■ Microbiome: Create a diverse microbiome
where beneficial bacteria outnumber non-beneficial bacteria. Keep opportunistic pathogens
response mounted by the animal uses energy
and can negatively impact growth if the immune response is sustained or uncontrolled.
