Model Pendugaan Energi Metabolis Pakan dan Bahan Pakan Ayam Broiler Berdasarkan Analisis Proksimat dan Energi Bruto

This study aimed to make estimation model of metabolizable energy (ME) broiler chicken ration and feedstuffs based on proximate analysis gross (GE). The used multiple simple linear regression with in vivo data approach. A total 34 starter commercial data, 33 finisher 17 experimental 14 corn 8 palm kernel cake (PKC) from Center for Quality Testing Feed Certification Laboratory other research while the moisture content (MC), ash, crude protein (CP), ether extract (EE), fiber (CF), GE ME were as database analyzed using SPSS version 20. results showed that equation = 2,444.89 + 201.34x(MC) - 415.85x(ash) 0.87x(CP) 282.58x(EE) 284.96x(CF), 6,451.05 244.99x(MC) 226.72x(ash) 101.40x(EE) 363.12x(CF), 3,001.07 41.39x(MC) 19.49x(ash) 12.82 x(CP) 87.31x(EE) 160.99x(CF), ME= 8,504.07- 301.32x(MC) 196.41x(ash) -252.58x(CP) 114.52x(EE) 47.99x(CF) PKC 6,197.28 111.45x(CF) 3,821.79 0.15GE, 12,266.23 2.19 (GE), 1,416.83 0.398x(GE), -2,958.80 1.68x(GE), -5,769.41 2.09x(GE). These two models could be estimate ration, corn, whereas both not feed starter.
