Abstract. Sexually mature Indonesian native hens (Sentul hens) were housed singly in laying
cages and artificially inseminated with combination of three different levels of diluted pooled

sperm number and Insemination intervals had no significant interaction (P>0.05) on % fertility
and hatchability. The best fertility around 90 %; P
