Abstract

Computer-assisted Semen Analyzer (CASA)-based analysis of extended semen from 18 adult Paraoakan Philippine native chickens using coconut water (CW) with either tomato juice or garlic extract were carried out in this study. Only extended semen samples passing the preliminary quality evaluation were further analyzed. Pooled semen were randomly distributed into four types of semen extender: (1) Ringer’s solution (RS), (2) RS + 20% CW + 0.02 g sodium phosphate (SP), (3) RS + 20% CW + 7% tomato juice + 0.04 g SP, and (4) RS + 20% CW + 2% garlic extract + 0.04 g SP and stored at either low (7–10 °C) or room (22–25 °C) temperature. The procedure was done for 13 collection periods, which served as the blocking factor. Results showed that except for garlic-supplemented extender, semen diluted with other types of extender and maintained at low temperature (7–10 °C) demonstrated the longest average shelf life, which is characterized by the period of time observed before sperm motility falls below 20%. Collectively, the addition of 20% CW on RS, with supplementation of 7% tomato juice can maintain sperm motility above 20% for 24 h at low temperature. This can be attributed to the chemical composition of CW and tomato juice that are beneficial to sperm cell metabolism, control of pH, and osmotic pressure and inhibition of microbial growth. Results also showed that CW can be used as an effective and economical partial substitute to RS.
