This study aimed to evaluate the effect of powered coconut water as preservant of cocks semen in different times. The experimental method was completely randomized, with treatments constituted by different times (1, 5, 10 and 15 minutes) of powered coconut water as preservant of cocks semen (Rhode Island Red lineage with 30-weeks). After collect and use of powered coconut water as preservant, the semen samples were used for inseminated of breeders of same lineage and age (16 per treatment). 280 eggs were collected for evaluation of effects on chicks (70 eggs per treatment). Were evaluated the incubation yields, chick/egg relation and gastrointestinal tract development of chicks. The data collected were submitted for variance analysis and evaluated by Tukey test at 5% of significance. Differences (p<0.05) were observed in incubation yields, chick/egg relation and gastrointestinal tract development, with the exception (p>0.05) of oropharynx + oesophagus length and yolk sac weight. From these results, it was concluded that the powered coconut water can be used as preservation of cocks semen up to 15 minutes. Cells exposed more time to nutrients provided by the powdered coconut water showed eggs and chicks most heavier, and better results in the incubation yields and embryo development.
