New concepts in pediatric nutrition.
The ultimate goal of feeding puppies and kittens is to ensure a healthy adult. The specific objectives, however, are to optimize growth, minimize risk factors for disease, and achieve optimal health and longevity. Minimum nutrient requirements are easiest to determine in growing animals using growth rates as the nutritional marker. These levels ensure a minimum level of good health in most animals. Nevertheless, the optimal nutrient levels for growth may not represent the optimal levels for other physiologic functions (e.g., immune function, disease prevention, behavior). Nutritional requirements for growing animals are being redefined using physiologic parameters other than growth rate. The most common causes of malnutrition in the neonate seem to be protein-energy deficiency or overnutrition in the perinatal period. Single micronutrient abnormalities are relatively uncommon. Nevertheless, the nutritional status during neonatal development is known to affect genetic expression and to have a lifelong impact. It is thus important to tailor the nutritional plan to the individual at each life stage and to remember that pediatric nutrition should start before conception.
