You can see why Avi-Sci, Inc recommends that you listen to the Surgeon General of the United States
when he recommends controlling your intake of fat to be less than 30% of the calories and that the fat be
comprised mostly of unsaturated type fat. Also, you should be certain to have adequate protein and exercise,
and no smoking. These recommendations are applicable to birds. Dr D's feeds are formulated with these
recommendations in mind because they apply to sound nutritional principles. You say your bird does not
smoke! When one smokes in the bird's presence and it breathes in the smoke that is exhaled or that which
floats off the cigarette, those conditions are not conducive to good health. I have heard about gout being
diagnosed in birds and that too much protein in the diet was being blamed for the condition. This raises
several questions dealing with the diagnoses. The actual cause of the problem and whether too much protein
(actually amino acids) in the diet was responsible for the condition. Gout reflects a kidney problem, and many
physiological changes can cause kidney problems. An ionic imbalance in the body (blood reflects this) is a
most common cause. Urate production markedly increases and sometimes this is a secondary problem
rather than the primary cause of the sickness. So, one has to be careful how to diagnose this clinical sign to

One driving force to eat is the body's mechanism to maintain it's body temperature. This is true for all
warm-blooded animals, especially birds, which have a much higher body temperature than humans. In fact,
caloric concentration of the diet is very important in dietary formulations in order to arrive at the proper
balance of body heat output Vs heat input. The diet supplies the heat via calories, and the calories are
necessary to maintain body temperature. The calories can come from fats, carbohydrates, and (believe it)
protein or amino acids. We do not want to bum protein or amino acids for energy because of reasons that
will be discussed at another time. Obesity occurs when the heat input (calories) exceeds the heat output.
Extra calories not used for energy are converted to fat. There are many factors that need to be considered
when formulating diets, and one of these is the energy (calorie) concentration of the diet. Based on that
energy concentration, a diet can be formulated to be correct to maintain weight, or create an obese situation,
or one for losing weight.
Determining the correct caloric value is the secret for making certain that diets do not make sedentary
pet birds fat. Instead, the diet must be formulated to create a slim bird that has a better chance for a longer
life. Dr D's formulations are designed to make birds converted from seed-type diets to lose their excess fat
and slim down to a "youthful" figure. Those that are fed Dr D's pelleted diets maintain their slim figures. You
will note that many show judge's grades favor fat birds, which actually is contrary to all of the health rules for
animals. Whoever controls the judging rules should take notice that fatty shapes are not what is best for the
birds. These are old time rules that were in existence before pelleted diets came into being and when seeds
were mostly what one would feed. This is not 1940, and it is time that the judge's committees recognize that
good health habits arrive from proper nutrition, and that proper nutrition for birds is just as important as
proper nutrition is for people. That means keeping the body from depositing excess fat. So, the rules for
judging should change and the emphasis should be on birds that are not fat. This would also improve
breeding since fat animals do not breed as well.
