Penelitian ini bertujuan untuk mengetahui perbedaan performa ayam broiler pada fase starter dan finisher yang dipelihara pada ketinggian lantai kandang berbeda dengan sistem closed house dengan populasi 16.000 ekor ayam per kandang strain Ross CP-707. Parameter yang diamati meliputi konsumsi pakan, pertambahan bobot badan harian (PBBH), Feed Conversion Ratio (FCR), deplesi, serta Indeks Performa (IP). Data diperoleh melalui observasi langsung selama satu periode pemeliharaan di kandang A CV Dian Pratama. Hasil penelitian menunjukkan bahwa konsumsi pakan pada lantai 1 cenderung lebih tinggi dibandingkan lantai 2, namun hasil uji statistik menunjukkan tidak terdapat perbedaan nyata (P>0,05). Nilai PBBH pada kedua lantai relatif sama pada fase starter maupun finisher. Nilai FCR pada lantai 2 cenderung lebih rendah yang menunjukkan efisiensi pakan lebih baik, tetapi secara statistik tidak berbeda nyata (P>0,05). Persentase deplesi pada kedua lantai berada dalam kisaran normal. Nilai Indeks Performa pada lantai 2 sebesar 352 lebih tinggi dibandingkan lantai 1 sebesar 338. Secara keseluruhan, perbedaan lantai kandang dalam sistem closed house tidak memberikan pengaruh signifikan terhadap performa produksi broiler.

This study aimed to determine the differences in broiler performance during the starter and finisher phases raised at different floor levels in a closed house system with a population of 16,000 birds per house of Ross CP-707 strain. The observed parameters included feed consumption, average daily gain (ADG), feed conversion ratio (FCR), depletion, and performance index (PI). The data were obtained through direct observation during one production cycle in house A of CV Dian Pratama. The results showed that feed consumption on the first floor tended to be higher than that on the second floor; however, statistical analysis indicated no significant difference (P>0.05). The ADG values on both floors were relatively similar during both the starter and finisher phases. The FCR value on the second floor tended to be lower, indicating better feed efficiency, but statistically it was not significantly different (P>0.05). The depletion percentage on both floors was within the normal range. The performance index value on the second floor was 352, which was higher than that on the first floor (338). Overall, differences in floor levels in the closed house system did not have a significant effect on broiler production performance.
