Objective: To evaluate the effect of high- and low-protein diets with or without tryptophan supplementation on behavior of dogs with dominance aggression, territorial aggression, and hyperactivity. Design: Prospective crossover study. Animals: 11 dogs with dominance aggression, 11 dogs with territorial aggression, and 11 dogs with hyperactivity. Two of the diets 1 low-protein and 1 high-protein were supplemented with tryptophan. Owners scored their dog’s behavior daily by use of customized behavioral score sheets. Mean weekly values of 5 behavioral measures and serum concentrations of serotonin and tryptophan were determined at the end of each dietary period. Results: For dominance aggression, behavioral scores were highest in dogs fed unsupplemented high-protein rations. For territorial aggression, [corrected] tryptophan-supplemented low-protein diets were associated with significantly lower behavioral scores than low-protein diets without tryptophan supplements. Conclusions and clinical relevance: For dogs with dominance aggression, the addition of tryptophan to high-protein diets or change to a low-protein diet may reduce aggression. For dogs with territorial aggression, tryptophan supplementation of a low-protein diet may be helpful in reducing aggression. Abstract Objective: To evaluate the effect of high- and low-protein diets with or without tryptophan supplementation on behavior of dogs with dominance aggression, territorial aggression, and hyperactivity.
However, you may have heard friends, dog trainers, or even veterinarians talking about feeding a low protein diet to treat behavior issues. But what does a low-protein diet really mean, and how do these testimonials compare to the science? Unfortunately using terms like low or high can be rather confusing in pet nutrition. Healthy adult dogs over one year of age need a minimum of 4. You can convert the numbers by using the calculator here. Each trainer, veterinarian, or nutritionist might have different ranges for what they consider in each category. So long as diets are nutritionally complete and balanced for your pet are above the minimum 4.
Know diet aggression protein high and can help nothing but
This then increases the relative amount of tryptophan, which due to enzyme kinetics supposedly increases the amount of serotonin produced. Reply to this topic Start new topic. Lieberman reported that this amino acid reduced sensitivity to pain. There is also no maximum or safe upper limit for protein, but some pets may have limitations on the protein they can safely consume due to medical conditions. Posted November 25, edited.
