dc.description.abstractSiruvidai and Peruvidai chicken are the major indigenous chicken ecotypes of Tamil Nadu state, India. A study was conducted to assess the fertility and hatchability of Siruvidai chicken hatching eggs incubated in a homestead incubator. The fertility, hatchability and embryonic mortality were recorded. The eggs failed to hatch out were break opened to determine the stage of embryonic mortality. The average fertility rate ranged from 85.00 to 91.67% in different hatches with the average value of 88.41%. The hatchability on total egg set ranged from 81.71 to 85.87% and the overall mean was 84.19; whereas the hatchability on fertile egg set ranged between 92.73 and 98.75 with the mean value of 95.28%. The breakopen study of unhatched eggs revealed 2.57% early embryonic mortality (range: 1.25 – 3.64%), 0.84% mid embryonic mortality (range: 0.00 to 1.82%) and 1.31% of late embryonic mortality including dead in shell (range: 0.00 to 2.11%). The total embryonic mortality was 4.72% with the values ranging from 1.25 to 7.27%. The results indicated good reproductive performance of indigenous Siruvidai chicken and efficient hatching of its eggs when homestead incubator is used.en_US
