بعض المعادلات لقياس كفاءة الغذاء ومعدل النمو

DIFFERENT FORMULATIONS FOR MEASURING FEED EFFICIENCY AND GROWTH RATE 






ظواهر الهضم

for the whole diet


for one nutrient


where

I = feed intake
xi,d = concentration of ingredients in diet
F = faeces
xi,f = concentration of ingredients in diet

IN = nutrient intake 
xN,d = concentration of nutrient in diet
FN = nutrient in faeces 
xN,f = concentration of nutrient in faeces



where

B = final body protein
B0 = initial body protein
I = protein intake




Growth efficiency 



where

G = growth in kJ/day
I = food ration in kJ/day
M = maintenance ration in kJ/day
