Abstract

The objetive of this study was to evaluate pregnancy rates in ewes using extenders based on coconut water (in natura: NCW or in powder: PCW-102®) following intra - cervical (Trial 1) or intrauterine laparoscopic insemination (Trial 2). Trial 1. Semen from 4 Santa Inês rams were collected, diluted at 32°C (T1: NCW; T2: PCW-102®) and cooled to 4°C. 56 adult Santa Inês ewes were inseminated intra-cervically following syncronization, 31 using the extender NCW and 25 the extender PCW-102®. Trial 2. Semen from 5 rams (Santa Inês: n=04; Dorper n=01) were collected and processed as described. 64 adult crossbred multiparous ewes were inseminated intrauterine by laparoscopy following oestrus syncronization. 37 ewes using the extender NCW and 27 the extender PCW-102®. The pregnancy diagnosis was performed by ultrasonography. The fertility rates between treatments for each method of insemination and within each extender for both methods were analysed by Chi-square test (p<0,05). The pregnancy rates following intra-cervical (NCW: 25.8% vs PCW-102®: 48%) and intrauterine (NCW: 72.9% vs 70.3%) inseminations were not influenced by the extenders. The pregnancy rate was influenced by insemination method (intra-cervical: 35.7% vs laparoscopy: 71.8%; p<0,05). The extenders based coconut water as basis can be used following cervical or intra-uterine laparoscopic inseminations in ewes from Northeast of Brazil under field conditions.
