Post-Weaning Growth Performance of Three- Meat Type Breeds of Rabbits Oryctolagus cuniculus linn. and their Crosses as Influenced by Three Levels of Nutrition. Major Professor : Francisco F. Penalba A factorial experiment in completely randomized design was conducted to measure and evaluate the growth rate, feed consumption and feed efficiency of three meat-type of rabbits and their single crosses raised from 63 to 105 days old as in-fluenced by three dietary levels. Significant differences in all traits evaluated due to dietary levels were observed. . In general marked decrease in performance on all traits evaluated was noted among experimental rabbits fed with all-roughage diet. Significant differences in performance due to effect of Datin, type wore noted on cumulative weekly live weight from days 70 to 105, and for cumulative weekly gain in weight from days 70 and 84 to 105. On day 779 effect of mating type of cumulative weekly gain in weight was not significant, Matims - XN (23.09 /), Ow X Ow (21.36 6/d) and Cw X N (7.47 g/d) produced the highest ADG values while Cw X Cw (12.30 L/,09 C X C (13.89 ad) and C X N (3.00 ad) produced the lowest ADG values for experimental rabbits fed with all-concentrate, 50 percent concentrate plus roughage, and all-roughage diets, respectively. Results implied that the best mating combinations, taking ADG as the main consideration, were N X N, Ow X Ow and Ow X N for all concentrate, 50 percent concentrate plus roughage, and all roughage diets, respectively. Variations in performance of mating types for feed efficiency and total feed intake were not statistically significant Interactions effects between mating types and dietary levels were highly significant for average daily gain, total feed in-take, average daily crude protein intake and cumulative weekly gain in weight. In contrast, no significant interaction effect was noted on cumulative weekly body weight. The variations in income over feed cost (IOFC) among mating types and dietary levels were highly significant. Results implied that inclusion of roughage as part of the diet for rabbits reduced production cost and consequently improve the income. Finally, variations in live weight gain in weight and average daily again of purebred rabbits (C X C, Ow X Ow, N X N) were not significantly different from the crossbred rabbits (C X Cw, Cw X II', C X M.

A factorial experiment in completely randomized design was conducted to measure and evaluate the growth rate, feed consumption and feed efficiency of three meat-type of rabbits and their single crosses raised from 63 to 105 days old as in-fluenced by three dietary levels.
Significant differences in all traits evaluated due to dietary levels were observed. . In general marked decrease in performance on all traits evaluated was noted among experimental rabbits fed with all-roughage diet.
Significant differences in performance due to effect of Datin, type wore noted on cumulative weekly live weight from days 70 to 105, and for cumulative weekly gain in weight from days 70 and 84 to 105. On day 779 effect of mating type of cumulative weekly gain in weight was not significant, Matims - XN (23.09 /), Ow X Ow (21.36 6/d) and Cw X N (7.47 g/d) produced the highest ADG values while Cw X Cw (12.30 L/,09 C X C (13.89 ad) and C X N (3.00 ad) produced the lowest ADG values for experimental rabbits fed with all-concentrate, 50 percent concentrate plus roughage, and all-roughage diets, respectively. Results implied that the best mating combinations, taking ADG as the main consideration, were N X N, Ow X Ow and Ow X N for all concentrate, 50 percent concentrate plus roughage, and all roughage diets, respectively. Variations in performance of mating types for feed efficiency and total feed intake were not statistically significant
Interactions effects between mating types and dietary levels were highly significant for average daily gain, total feed in-take, average daily crude protein intake and cumulative weekly gain in weight. In contrast, no significant interaction effect was noted on cumulative weekly body weight.
The variations in income over feed cost (IOFC) among mating types and dietary levels were highly significant. Results implied that inclusion of roughage as part of the diet for rabbits reduced production cost and consequently improve the income. Finally, variations in live weight gain in weight and average daily again of purebred rabbits (C X C, Ow X Ow, N X N) were not significantly different from the crossbred rabbits (C X Cw, Cw X II', C X M.
