5. WHAT IS THE REASON FOR
THIS MORE RAPID GROWTH?
Industrial poultry production is based on 4 pillars: genetics, nutrition,
management, and health, whose improvements have resulted in better growth
rates. Also, the permanent incorporation of technologies and equipment that
further improve natural results enables higher productivity levels.
6. HOW IMPORTANT IS THE
NUTRITION OF CHICKEN?
Science has taught us the nutritional needs of birds at each of their life stages.
Based on this knowledge, different types of balanced feeds started to be
developed, prepared by specialists who adjusted the nutritional needs of birds.
As such, between 3 to 4 types of feed are used during their 42 days of life, and
the basic composition is made with corn and soybean meal.

WHAT WAS THE GROWTH RATE
OF CHICKEN BEFORE AND HOW
MUCH DO THEY GROW NOW?
In the 1960s, when the industrial production of
poultry products started, the birds reached a weight
of approximately 2 kg in 80 days and consumed 5.8
kg of food. Currently, birds reach an average weight
of 2.6 kg in just 42 days of life and consume 4.6 kg
of food. The growth pattern of birds is so fast that a
1-day chick that weighs 50g will weigh approximately
2.5kg in 40 days, meaning a 50-fold growth rate from
its initial weight.
7. HOW DOES GENETICS INFLUENCE
THE GROWTH OF BIRDS?
Within a flock of birds, those with excellent productive characteristics (fast
growth, muscle development, nutritional efficiency, among others) are selected
and bred in order to genetically pass desirable characteristics to their offspring.
Among their descendants, those showing the desired traits are once again
selected and bred. The advantages seen in current genetic lineages result from
intensive classical genetic breeding programs. There is no genetic engineering
in the development of new lineages, but permanent selection breeding enables
the achievement of predetermined goals.
