%A 1314141031 Made Lupita Sari %T PERFORMA AYAM KUB (KAMPUNG UNGGUL BALITNAK) PERIODE GROWER PADA PEMBERIAN RANSUM DENGAN PROTEIN KASAR YANG BERBEDA %X Penelitian ini bertujuan untuk mengetahui pengaruh pemberian ransum dengan kadar protein kasar berbeda terhadap performa ayam KUB. Penelitian dilaksanakan pada Juli--Agustus 2017 di kandang unggas Laboratorium Lapang Terpadu, Fakultas Pertanian, Universitas Lampung. Ayam yang digunakan adalah ayam KUB berumur 4--8 minggu sebanyak 95 ekor. Rancangan percobaan yang digunakan, yaitu Rancangan Acak Lengkap (RAL) dengan 3 perlakuan dan 8 ulangan. Setiap satu satuan percobaan terdiri dari 4 ekor ayam KUB. Perlakuan yang diberikan adalah ransum dengan kadar protein kasar sebesar P0 : 15,60%; P1 : 12,81%; P2 : 10,05%. Data yang diperoleh dianalisis ragam menggunakan taraf nyata 5% dan dilanjutkan dengan uji BNT. Peubah yang diamati adalah konsumsi ransum, konsumsi protein, pertambahan berat tubuh, konversi ransum, dan income over feed cost. Hasil penelitian menunjukkan bahwa ransum dengan kadar protein kasar berbeda berpengaruh tidak nyata (P>0,05) terhadap konsumsi ransum, konsumsi protein, pertambahan berat tubuh, konversi ransum, dan income over feed cost ayam KUB periode grower. Kata kunci : Performa, Ayam Kampung Unggul Balitnak (KUB), ransum, protein kasar. abstract The aims of this research is to know the effect of the different crude protein ration to the performance of KUB chicken. The research was conducted in July to August 2017 in poultry cage of Integrated Field Laboratory, Agriculture Faculty, Lampung University. The amount of chickens that is used in this research were 95 chickens at the age of 4-- 8 weeks old. Every trial units consist of 4 KUB chickens. The treatment that used are the ratio of different crude protein, there are P0: 15,60%; P1: 12,81%; P2: 10,05%. The obtaining data were analyzed by using the analysis of variance of 5% level and will continued by BNT Test. The observed variabels are feed consumption, protein consumption, body weight gain, feed conversion, and income over feed cost. The result showed that the different crude protein ratio has not significant (P> 0,05) on feed consumption, protein consumption, body weight gain, feed conversion, and income over feed cost.
