PENGARUH PEMBERIAN CORN STEEP LIQUOR DAN ASAM AMINO ESENSIAL PADA AIR MINUM TERHADAP PERFORMA BROILER FINISHER

Abstract

Penelitian ini bertujuan untuk mengkaji pengaruh pemberian Corn Steep Liquor (CSL) dan asam amino esensial melalui air minum terhadap konsumsi pakan, pertambahan bobot badan, dan Feed Conversion Ratio (FCR) ayam broiler fase *finisher*. Sebanyak 80 ekor ayam broiler fase *finisher* berumur 22 hari digunakan dalam Rancangan Acak Lengkap (RAL) dengan empat perlakuan dan empat ulangan. Perlakuan yang diterapkan adalah P0 (kontrol), P1 (4% asam amino esensial dan CSL), P2 (5%), dan P3 (6%). Uji Beda Nyata Terkecil (BNT) dilakukan setelah analisis data menggunakan Analisis Varians (ANOVA). Hasil penelitian menunjukkan bahwa konsumsi pakan dan pertambahan bobot badan dipengaruhi secara nyata (P<0,05) oleh pemberian CSL dan asam amino esensial, sedangkan nilai FCR dipengaruhi secara sangat nyata (P<0,01). Perlakuan P3 memberikan hasil terbaik dengan konsumsi pakan terendah (1701,80 g), pertambahan bobot badan tertinggi (1435,90 g), dan nilai FCR terendah (1,43). Pemberian CSL dan asam amino esensial melalui air minum berpotensi meningkatkan efisiensi penggunaan pakan dan performa broiler fase finisher.

The Effect of Corn Steep Liquor and Essential Amino Acids Supplementation in Drinking Water on the Performance of Finisher Broilers.

Abstract

This study aimed to examine the effect of administering *Corn Steep Liquor* (CSL) and essential amino acids via drinking water on feed intake, body weight gain, and the Feed Conversion Ratio (FCR) of broiler chickens during the finisher phase. A total of 80 broiler chickens (22 days old) were used in a Completely Randomized Design (CRD) with four treatments and four replicates. The treatments applied were P0 (control), P1 (4% essential amino acids and CSL), P2 (5%), and P3 (6%). The Least Significant Difference (LSD) test was conducted following data analysis using Analysis of Variance (ANOVA). The results showed that feed intake and body weight gain were significantly affected (P<0.05) by the administration of CSL and essential amino acids, while the FCR value was highly significantly affected (P<0.01). The P3 treatment produced the best performance, with the lowest feed intake (1701.80 g), the highest body weight gain (1435.90 g), and the lowest FCR (1.43). Supplementation of CSL and essential amino acids through drinking water has the potential to improve feed utilization efficiency and enhance the performance of finisher broiler chickens.
