PERBEDAAN ROW TERHADAP PERFORMAN AYAM PETELUR FASE GROWER DALAM KANDANG CLOSED HOUSE

This study aims to evaluate the impact of row differences on the productivity of Isa Brown laying hens during the grower phase, with a focus on body weight gain and uniformity. The research was conducted at Slorok Farm, Blitar Regency using a close house system. A total of 192 laying hens were placed in each row 1 and row 2 which had been determined in a closed cage. Weight gain and uniformity were measured weekly from 7 to 10 weeks of age. The results were analyzed using the unpaired T test to determine significant differences between the two levels. The results of the research showed that there was no real difference in body weight gain row 1 average 105 g every week and row 2 average 104 g every week and uniformity Row 1 average 92% and Row 2 average 94% uniformity,this shows that the placement of the Row does not affect the productivity of Isa Brown laying hens in the grower phase with a closed cage system.
