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 need of feed, P2 = 80% from total feed requirement and P3 = 60% from the total need of feed). Feed was given in the amount of rabbits requirement, in which 100% of the total need was calculated based on body weight (6.7% from body weight in accordance with dried material of ration), and second factor was 3 levels of slaughter age (U1= 120 days, U2= 150 days, U3= 180 days) and each treatment was repeated 6 times. The data was 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. Hasil penelitian menunjukkan bahwa terdapat interaksi antara umur pemotongan dengan pembatasan pakan. Pakan dengan 80% dari kebutuhan dan umur pemotongan 150 hari sangat efisient untuk memproduksi kulit kelinci Rex dengan berat 261.0 ± 30.33 g, luas 928.0 ± 75.5 cm2, tebal epidermis 32.50 ± 1.1µ, dermis 2685.50 ± 15.0 µ. There was an interaction between slaughtered age and the amount of feed given to Rex Rabbits. Feeding 80% from the amount need of feed and slaughtered age of 150 day were the most efficient in producing pelt of Rex rabbits.
