The effect of restricted feeding and different of slaughtering age on production of rex rabbit pelt

The purpose of this research is to study the interaction between slaughter age and restricted feed,as well as the influence of each factor on the production of rex rabbits pelt. randomized block design with factorial was used in this experiment with the first factor was 3 levels of restricted feeding treatment where the amount of feed as follow: p1= 100 % from the total feed requirement,p2 = 80% from total feed requirement and p3 = 60% from the total feed requirement. feed was given in the amount of rabbits requirement,in which 100% of the total requirement was calculated based on body weight (6.7% of body weight in dry matter basis),and second factor was 3 levels of slaughter age (u1= 120 d,u2= 150 d,u3 = 180 d) and each treatment was repeated 6 times. the data were analyzed by anova,and analyzing between the treatments used contrast orthogonal. the variable measured were pelt production (weight pelt,width pelt,thickness dermis and epidermis) of rex rabbit. there was an interaction betwen slaughtered age and the amount of feed given to rex rabbits. feeding 80% from the total feed requirement and the slaughtered age at 150 d were the most efficient in producing pelt of rex rabbits,with weight 261.0 ± 30.33 g,width 928.0 ± 75.5 cm2,and epidermal thickness 32.50 ± 1.1μ,and dermis 2685.50 ± 15.0 μ. © 2010 diponegoro university. all rights reserved.
