A total of ninety seven pre-pubertal Bunaji (BJ) and Friesian-Bunaji (FR $\times$ BJ) heifers were allotted randomly to two treatments groups for a period of 15 months. The treatment groups consisted of the followings: Mature Bull Exposure (MBE) and No Bull Exposure (NBE). Heifers were body condition scored and their live weights recorded on 28 days consecutive intervals. A heifer tactile stimulation in bull bio-stimulation. was considered to have attained puberty if she displayed oestrus, had a palpable corpus luteum with an associated P4 concentration $> $ 1ng$\cdot$mL$^{-1}$. The onset of puberty was significantly earlier in MBE heifers (23.1 $\pm$ 0.4 months) than NBE heifers (26.4 $\pm$ 0.4 months). The mean ages at puberty for ...
