Penelitian berjudul “Pengaruh Tingkat Kepadatan Kandang Tertutup Terhadap Pertumbuhan Mingguan Dan Bobot Badan Umur 35 Hari Ayam Broiler Strain Ross’’. Tujuan penelitian ini adalah mengkaji pengaruh tingkat kepadatan kandang tertutup terhadap pertumbuhan mingguan dan bobot badan umur 35 hari ayam broiler strain ross, memberikan informasi ilmiah, dan sebagai acuan bagi peternak dalam manajemen perkandangan model kandang tertutup. Materi penelitian yang digunakan adalah DOC broiler strain Ross sebanyak 200 ekor unsex pemeliharaan selama 35 hari dari DOC hingga panen, pakan complete feed broiler I dan II. Peralatan yang digunakan yaitu kandang tertutup dan peralatan kandang. Metode penelitian dilakukan berdasarkan rancangan acak lengkap (RAL). Perlakuan yang diujicobakan adalah kepadatan kandang tertutup berdasarkan berat badan ayam pada umur 21-35 hari, yang terdiri atas 5 perlakuan yaitu, T_1 (8 ekor/m^2), T_2 (9 ekor/m^2), T_3 (10 ekor/m^2), T_4 (11 ekor/m^2), T_5 (12 ekor/m^2), dan setiap perlakuan diulang 4 kali. Data hasil penelitian ditabulasikan, kemudian dianalisis menggunakan analisis variansi (ANAVA) dan dilanjutkan dengan uji DMRT test. Hasil penelitian dengan perlakuan pertumbuhan bobot badan minggu ke-4 diperoleh yang tertinggi T_1 (778,77 ± 11,67); dan terendah T_4 (714,74 ± 26,02). Pertumbuhan bobot badan minggu ke-5 diperoleh yang tertinggi  T_2 (646,94 ± 52,26) dan terendah T_5 (531,85 ± 35,59). Bobot badan umur 35 hari diperoleh yang tertinggi T_2 (2499,30 ± 76,72) dan terendah T_5 (2302,91 ± 61,83). Hasil analisis variansi menunjukan bahwa pengaruh tingkat kepadatan kandang tertutup berpengaruh sangat nyata (P<0.01) terhadap pertumbuhan bobot badan ayam minggu ke-4 dan berpengaruh nyata (P<0.05) terhadap bobot badan umur 35 hari, namun berpengaruh tidak nyata (P>0.05) terhadap pertumbuhan bobot badan ayam minggu ke-5. Kesimpulan bahwa semakin tinggi kepadatan kandangnya maka akan semakin turun bobot badan ayam broiler. Pada perlakuan T_1  dan T_2 dengan kepadatan kandang 8 dan 9 ekor/m^2  merupakan perlakuan dengan kepadatan yang paling ideal dibandingkan dengan perlakuan lainnya.

The study entitled "The Effect of Closed Cage Density Rate on Weekly Growth and Body Weight Age 35 Days of Ross Strain Broiler Chickens". The purpose of this study was to determine the effect of closed cage density on the weekly growth and body weight of 35-day of Ross strain broilers chickens, to provide scientific information regarding, and as a reference for breeders in managing a closed cage model. The research material used was 200 DOC broiler strain Ross with maintenance elements for 35 days from DOC until harvest, complete feed broiler I and II. The equipment used was a closed cage and cage equipment. The research method used a completely randomized design (CRD).  The treatment tested was closed cage density based on body weight of chickens aged 21-35 days, consisting of 5 treatments, T1 (8 chickens/m2), T2 (9 chickens/m2), T3 (10 chickens/m2), T4 (11 chickens/m2), T5 (12 chickens/m2), and each treatment was repeated 4 times. The research data was tabulated, then analyzed using analysis of variance (ANOVA), and continued with the DMRT test. The results of the study with weight gain treatment at the fourth week were obtained the highest T1 (778,77 ± 11,67) and the lowest T4 (714,74 ± 26,02). Weight gain in the fifth week were obtained the highest T2 (646,94 ± 52,26) and the lowest T5 (531,85 ± 35,59). The weight of the chickens at age 35 days was obtained the highest T2 (2499,30 ± 76,72) and the lowest T5 (2302,91 ± 61,83). The results of the analysis of variance showed that the effect of the level of closed cage density had a very significant effect (P<0.01) on the body weight gain of the broiler in the 4th week and had a significant effect (P<0.05) on the bodyweight of the harvest, but had no significant effect (P>0.05) to the weight gain of broiler at week -5. The conclusion is the denser the cage, the lower the bodyweight of the broilers will be. In T1 and T2 treatment with a cage density of 8 and 9 chickens/was the treatment with the most ideal density compared to other treatments.
