Abstract: This study aims to determine the egg production of layer strain isa brown with different patterns of distribution of rations in the morning and in the afternoon. This research was carried out in Saentis Village, Percut Sei Tuan District, Deli Serdang Regency using 4,000 layer strain ISA brown chickens aged 20 weeks consisting of the first treatment using 200 layer strain ISA brown chickens with management giving rations 60% in the morning and 40% during the day, the second treatment used 2,000 layer chickens strain ISA brown with 50% ration management in the morning and 50% in the afternoon. Data were collected for 3 months of egg production (20 weeks to 32 weeks of chickens). Observations of research carried out by recording egg production every day for each treatment carried out. Data processing is done by tabulating the data and averaging egg production in the form of a percentage. The results obtained showed that egg production with a ration treatment of 60% in the morning and 40% in the afternoon resulted in an average egg production of 76.94% and in the treatment of giving a ration of 50% in the morning and 50% in the afternoon resulted in an egg production of 80, 40%. It can be seen that giving rations with the same amount in the morning and afternoon resulted in more egg production compared to giving rations with a higher amount in the morning and in comparison rations in the afternoon and the best ration conversion was giving 50% rations in the morning and 50% in the afternoon by 2.24 and giving 60% rations in the morning and 40% in the afternoon resulted in a ration conversion of 2.47. This is because the distribution of nutrients is more evenly distributed in the same amount, so the egg formation process can run optimally every time supported by the available nutritional value and the maintenance of the condition of the ration that is always fresh every time it is given so that it can produce better egg production and good ration conversion. 24 and giving rations of 60% in the morning and 40% in the afternoon resulted in a ration conversion of 2.47.
