Description
| - Vodní životní prostředí a unikátní biologické vlastnosti komplikují zjištění zjevně stravitelných bílkovin (ADP) a zjevně využitelných aminokyselin (AAAA) obsažených v ingrediencích krmiv pro ryby. Proto je nutné využití alternativních metod výpočtů, jako prognózy na základě chemického složení krmiv. Analýza 617 průměrů z celkem 69 studií, které zhodnocovaly stravitelnost bílkovin u 73 různých složek krmiv a 35 druhů ryb, odhalila lineární závislost (ADP=-10.0731+0.8942 CP, R2=0.9462) mezi hrubým proteinem (CP; g/kg sušiny) a ADP (g/kg sušiny) obsažených v krmivu. Ve směsných dietách (n=831, 170 studií, 49 druhů ryb) je tento vztah popsán jako ADP=-51.4001+0.9872 CP (R2=0.8632). Ověření uvedeného s hodnotami z nezávislých studií prezentovaných s vysokým stupněm shody (R2>0.8000; chyba odhadu průměru <0.1100) mezi odhadovanými a určenými hodnotami. Profily AAAA ve složkách potravy a směsných dietách, vyjádřených v g/kg sušiny, jsou odhadnutelné (R2 většinou>0.9500) z obsahu aminokyselin pomoc (cs)
- An aquatic environment and unique biological characteristics complicate the determination of apparent digestible protein (ADP) and apparent available amino acid (AAAA) contents of feed ingredients and diets for fish. This urges for alternative methods of calculation, such as prediction from dietary chemical composition. Analysis of 617 means from 69 studies, which evaluated the protein digestibility of 73 feed ingredients with 35 fish species, revealed a linear relationship (ADP=-10.0731+0.8942 CP, R2=0.9462) between dietary crude protein (CP; g/kg dry weight) and ADP (g/kg dry weight) contents. In compound diets (n=831, 170 studies, 49 fish species) this relation was described by ADP=-51.4001+0.9872 CP (R2=0.8632). Validation of the above with values from independent studies presented a high degree of agreement (R2>0.8000; meanprediction error <0.1100) between predicted and determined values. AAAA profiles in feed ingredients and compound diets, expressed as g/kg dry weight, are predictable (R2
