Penelitian ini bertujuan untuk mengidentifikasi perbedaan produktivitas ayam broiler, yang diukur melalui pertambahan bobot badan (PBB) dan Feed Conversion Ratio (FCR), antara lantai 1 dan lantai 3 pada kandang tertutup bertingkat. Penelitian ini dilakukan di CV Dian Pratama Farm yang berlokasi di Desa Cendana, Kecamatan Kutasari, Kabupaten Purbalingga, Jawa Tengah. Materi penelitian yang digunakan adalah ayam broiler strain Cobb dengan populasi masing-masing 16.000 ekor pada lantai 1 dan lantai 3. Variabel yang diamati dalam penelitian ini adalah Feed Conversion Ratio dan pertambahan bobot badan ayam pedaging. Data diperoleh melalui survei dilapangan, data primer didapatkan dari recording dan data sekunder dari wawancara dengan kepala kandang. Data Primer yang telah didapatkan diuji menggunakan independent simple t-test. Hasil uji t berbeda nyata, rata-rata Pertumbuhan Bobot Badan (PBB) pada lantai 1 sebesar 1044,49 ± 27,34 g/ekor dan lantai 3 sebesar 1111,10 ± 41,70 g/ekor. Rata-rata Feed Conversion Ratio (FCR) lantai 1 sebesar 1,48 ± 0,03 dan lantai 3 sebesar 1,39 ± 0,05. Berdasarkan hasil penelitian, dapat disimpulkan bahwa pertambahan bobot badan dan nilai FCR ayam broiler yang dipelihara di lantai 1 dan lantai 3 menunjukkan perbedaan yang signifikan (P<0,05). Perbedaan ini diduga disebabkan oleh kondisi mikroklimat dan makroklimat yang lebih optimal di lantai 3, terutama terkait suhu, kelembapan, dan ventilasi. Selain itu, perbedaan signifikan pada nilai FCR antara kedua lantai juga teramati pada periode awal pemeliharaan, yaitu pada rentang usia 0-21 hari.

This research aimed to identify differences in broiler productivity, measured by Average Daily Gain (ADG) and Feed Conversion Ratio (FCR), between the first and third floors of a multi-tiered closed house. The study was conducted at CV Dian Pratama Farm located in Cendana Village, Kutasari Subdistrict, Purbalingga Regency, Central Java. The research material consisted of Cobb strain broiler chickens with a population of 16,000 birds on each of the first and third floors. The variables observed were Feed Conversion Ratio and the weight gain of broiler chickens. Data were collected through field surveys, with primary data obtained from daily records and secondary data from interviews with the farm manager. The primary data obtained were analyzed using an independent simple t-test. The t-test results showed a significant difference, with the average Average Daily Gain (ADG) on the first floor being 1044.49 ± 27.34 g/bird and on the third floor being 1111.10 ± 41.70 g/bird. The average Feed Conversion Ratio (FCR) on the first floor was 1.48 ± 0.03 and on the third floor was 1.39 ± 0.05. Based on the research results, it can be concluded that the average daily gain and FCR values of broiler chickens raised on the first and third floors showed a significant difference (P<0.05). This difference is thought to be due to the more optimal microclimatic and macroclimatic conditions on the third floor, particularly regarding temperature, humidity, and ventilation. In addition, a significant difference in FCR values between the two floors was also observed during the early rearing period, specifically between 0-21 days of age.
