The Effect of Three Dietary Crude Protein Levels on Digestibility and Tests Function in Male Pubertal Rabbits
Summary
Six healthy crossbred rabbits (New Zealand white &
Chinchilla) were assigned to each of three isocaloric
rations viz: treatment A (control) with 20% crude
protein on dry matter basis (CP), treatment B with 14%
CP and treatment C with 24% CP. The performance
parameters considered included dry matter and CP
digestibility, feed intake, growth rate, and reproduction
parameters like paired testes weight, paired testes
volume/density, gonadal sperm reserves and daily
sperm production. The results showed that CP
digestibility was significantly affected (P= 0.05) while
dry matter digestibility was not significantly affected.
Average weight gain was significantly different (P= 0.05) between treatment B and C but not between B
and C and control. There was no significant dietary effect on relative testis weight among treatments but
testis volume was significantly enhanced by dietary CP. Daily sperm production and gonadal sperm
reserves were significantly enhanced (P= 0.05) with increasing dietary CP. It is concluded that dietary
crude protein significantly enhances the reproduction efficiency of pubertal rabbits.
