Estimated parameters for allometric regression between excretion of urinary creatinine (mg/d) as a function of BW, cold carcass weight, and muscle weight
| Body weight, kg | |
| Goat | Ŷ = 17.28(±10.56)X1.0472(±0.17) |
| Sheep | Ŷ = 22.22(±17.37)X0.9563(±0.23) |
| Goat and sheep | Ŷ = 15.8(±7.23)X1.064(±0.13) |
| P = 0.37 | |
| Cold carcass weight, kg | |
| Goat | Ŷ = 74.48(±42.76)X0.7939(±0.22) |
| Sheep | Ŷ = 76.69(±31.81)X0.9221(±0.15) |
| Goat and Sheep | Ŷ = 65.19(±22.27)X0.8643(±0.13) |
| P = 0.15 | |
| Weight of muscle, kg | |
| Goat | Ŷ = 89.04(±31.44)X0.9797(±0.16) |
| Sheep | Ŷ = 109.8(±47.50)X0.8002(±0.20) |
| Goat and Sheep | P < 0.01 |
Equations obtained by comparison of nonlinear fit of a single or double allometric regression model using the X2, or model identity test (Regazzi et al., 1999); and the significant parameters (P < 0.05) were maintained in the adjusted equations.
