Effects of diet calcium : phosporus ratio and metabolizable energy content on development of osteochondrosis, foot bending and performance in blue foxes
The study evaluates the effects of two dietary Ca : P ratios (1·5 : 1 v. 2·5 : 1) and metabolizable energy (ME) contents (17·3 MJ/kg dry matter ( DM) v. 19·2 MJ/kg DM) on the development of osteochondrosis, foot bending and performance in juvenile male blue foxes (Alopex lagopus). Four experimental...

Four experimental groups (no. = 10 per group) were formed : (1) low energy, low Ca : P ( LELC); (2) normal energy, low Ca : P ( NELC); (3) low energy, normal Ca : P ( LENC); and (4) normal energy, normal Ca : P ( NENC).
