| Abstract |
|
In this trial 10 linear traits were measured to formulate regression
equations for body weight prediction in Sudan local rabbits. Traits measured
beside body weight (BW) were ear length (EAR), heart girth (HG), height
at withers (HTW), body length (BL), abdominal circumference (ABC),
distance from nose to shoulder (NTS), length of the fore limb (FL),
length of the hind limb (HL), thigh girth (TG) and tail length
(TL). These traits were measured at 3, 4, 5 months and over 5 (mature)
months of ages in both sexes. We found the highest correlations (highly
significant at P≤0.01) with body weight in all age groups. HG, BL and
ABC were chosen as the indicator traits in the regression equations. The
generated sex combined equations were Y= -749.76+41.89 HG+ 23.41
BL+17.15 ABC, Y=-348.17+24.52HG+27.02BL+14.19ABC and
Y=-2197.23+69.46GH+45.41BL+33.68 ABC for 3, 4 and above 5 months of age.
Obtained prediction equations have high values of R2
at 3 and mature ages (84- 0.59), moderate values at 4 months of ages
(0.57-0.37) and low values at 5 months of age (0.31-0.15). These values
suggested that prediction equations can be used efficiently in Sudanese
rabbits to predict live weight at 3, 4 months of age and mature ages.
