Summary:Pig breeding in Haiti : a difficult choice !. Three simple methods were tested to predict oestrus in adult Texel ewes in conjonction with progesterone essays or the use of vasectomized ram. The pH of the vaginal mucus enables oestrus detection : more acid during oestrous and more alkaline during the luteal phase. The use of cervico-vaginal mucus elasticity as a predictor of oestrus was difficult due to its scarcity during some phases of the cycle and even the total lack of mucus by some ewes. The temperature measurement has been ineffective for heat detection.
