Thirty-two (32) male rabbits of heterogeneous stock (California X New Zealand X Chinchilla crosses), agedbetween 8 and 12 weeks, weighing between 1100g and 1250g were used in an experiment to evaluate the effects of Gmelinaarborealeaf meal on sperm production rate, gonadal and extragonadal sperm reserves. Rabbit bucks were randomly allocated into four dietary treatments designated T1, T2, T3 and T4 containing 0%, 5%, 10% and 15% of Gmelinaarborea leaf meal respectively. The results showed significant (P>0.05) influence of diets on testes andepididymalweights.Rabbit bucks fed 15% Gmelinaarborea leaf meal showedhighly significant (P0.05) influence of the dietary treatment on daily sperm production (DSP) and daily sperm production per gram testis (DSPG). The results also indicated that Gmelinaarborea leaf meal up to 15% in dietdid not adversely affect sperm production and sperm reserves in rabbit bucks.
