Calcium requirement of growing rabbits.
T HE minimum calcium requirement of growing rabbits has not been determined. In practice dietary calcium levels have been based largely on information gained from other animals. Commercial rabbit diets commonly contain 0.8 to 1.0% calcium. Since the domestic rabbit is extensively used as an experimental animal and is increasingly used as a source of edible meat, particularly in the Los Angeles ...

Estimates of maintenance requirement of growing lambs.
1. Total body energy retention (ER) and metabolizable energy intake (MEI) values from experiments with 231 lambs (Suffolk male x (Border Leicester male x Cheviot female) female) housed indoors and given thirteen forage diets were used to estimate the metabolizable energy (ME) required for maintenance. 2. ER was measured using the comparative slaughter technique, and the lambs were fed at severa...
متن کاملProtein level affects the relative lysine requirement of growing rainbow trout (Oncorhynchus mykiss) fry.
The effect of two digestible protein levels (310 and 469 g/kg DM) on the relative lysine (Lys; g Lys/kg DM or g Lys/100 g protein) and the absolute Lys (g Lys intake/kg 0.75 per d) requirements was studied in rainbow trout fry using a dose-response trial. At each protein level, sixteen isoenergetic (22-23 MJ digestible energy/kg DM) diets were tested, involving a full range (2-70 g/kg DM) of si...
متن کاملEstimating the requirement of dietary crude protein for growing blue-breasted quail (Excalfactoria chinensis).
Two experiments were conducted to investigate the requirement for dietary crude protein (CP) in growing blue-breasted quail (BBQ). In Experiment 1, 300 1-day-old quails were randomly assigned to 10 groups according to a 2×5 factorial arrangement of treatments with two metabolisable energy (ME) levels (12.13 and 13.39 MJ/kg) and five CP concentrations (160, 190, 220, 250 and 280 g/kg) for 8 week...
