and digest it better, when raised on a rotating on-off
lighting program. A common program is two hours of
light, which initiates a feed consumption cycle, followed
by two hours of darkness, where birds rest. Variations
exist, but if combined with pelleted feeds, then birds
will consume the most feed possible. As a side note, it
must be remembered that
more feeding positions might
be required compared to
other management programs
to allow all birds to start eating at the same time.

Water
availability

It is without saying that without water there is no feed intake. Anything that causes a
reduction in water intake will
reduce feed intake. So, extra
care should be taken to ensure all birds have adequate
access to enough water of suitable quality. This story
about water has become a stereotype, but this is because
most facilities pay little to no attention to water intake.
In my opinion, a monthly check up of every aspect of
water provision should be assigned to a properly trained
member of the staff. Otherwise, we will keep looking
for solutions to problems that should not be there.

Flavors

Most, even nutritionists, believe birds have little if
any sense of taste. This is far from truth. If we compare
the number of taste buds between a bird and a mammal,
the latter usually wins. But, if we consider the number
of taste buds per volume in the oral cavity, the two suddenly become not much different. Today, nutritionists
are investigating the use of specific flavors to enhance
feed intake in broilers. In addition, nutritionists are
already aware of specific ingredients and additives that
depress feed intake. As such, there is scope in spending
some time considering the issue of palatability in birds
when formulating a new diet.

Antinutritional factors

Balanced diets

Certain antinutritional factors, apart from imparting an undesirable taste (bitter, for example), cause a
negative reaction at the gut level (inflammation, for
example). When this happens, birds will instinctively
reduce feed intake to the point they will stop eating if
the offending ingredient is above tolerable levels. Thus,
when we need to maximize feed intake, we can reduce
the number of ingredients that contains known antinutritional factors. We will replace them with others more
innocuous, but also more expensive, and here again, we
must balance expense versus profit.

Anyone who buys complete feeds assumes the
diets are well-balanced according to widely accepted
norms. This can be far from true. A well balanced
diet requires first the services of a qualified nutritionist - you cannot simply copy such a formula from the
internet or from the pages of a book. There is a huge
gap between example formulas shown for educational
purposes and those that should be manufactured for
commercial use. Lamentably, good nutritionists are expensive to hire, and many feed mills tend to improvise
(at best) or copy using feed labels and "intuition" (at
worst). In any case, a cheap feed can be produced this
way, but the birds will either not consume it readily or if
they do, they will waste one nutrient or the other or lack
a nutrient or two. Again, it takes a Ph.D. nutritionist 10
years of education and another 10 years of experience to
be able to produce a successful commercial formula. It
is not brain surgery, but it is not like sticking a bandage
to a papercut, either!
In brief, when broilers must grow faster or their feed
intake lags behind due to any cause, there are some
measures that can be employed with more or less success to entice them to eat more. Whether this succeeds
or not is best assessed by a professional manager with
the help of a qualified nutritionist. In the end, as this is
about a commercial enterprise, the profit-loss balance is
what will determine the application of one or the other
measure. ■
