Karakteristiky Jack Russell teriéra a energy needs
Jack Russell teriéři byli vyšlechtěni pro intenzivní hunting activities vyžadující extraordinary stamina a alertness. Jejich metabolická rychlost je o 10-15% vyšší než u běžných terierů podobné velikosti.
Průměrný 6kg Jack Russell potřebuje 450-600 kcal denně podle úrovně aktivity, což odpovídá 75-100 kcal per kg body weight. Working or highly active dogs mohou potřebovat až 700-800 kcal denně.
Mental stimulation requirements jsou equally important - nedostatek mentální stimulace vede k destructive behavior, excessive barking a compulsive activities. Nutrition může support both physical a cognitive function.
Optimální složení stravy pro hyperaktivní plemena
High-quality proteins (26-30%) jsou foundation pro sustained energy a muscle maintenance. Avoid highly processed protein meals; preferujte whole meat sources jako chicken, turkey, fish pro better amino acid profile.
Complex carbohydrates (40-45%) poskytují sustained energy release without blood sugar spikes které mohou exacerbovat hyperactivity. Sweet potato, brown rice, oats jsou preferable nad refined grains nebo high glycemic ingredients.
Moderate fat content (12-16%) supports coat health ale excessive fat může contribute k weight gain v less active periods. Omega-3 fatty acids are particularly important pro brain function a behavioral stability.
Nutrients pro behavioral balance
Tryptophan je amino acid prekurzor serotoninu který může help reduce anxiety a hyperactivity. Turkey, milk proteins, a some fish jsou good sources. Timing je important - avoid high tryptophan před high activity periods.
B-vitamins, especially B6 a thiamine, support nervous system function. Deficiency může worsen behavioral issues. Nutritional yeast, whole grains, liver jsou excellent sources, ale supplementation by měla být veterinary guided.
