Penelitian ini bertujuan membandingkan efek pemberian ampas kedelai nonfermentasi dan yang difermentasi Aspergillus niger terhadap jumlah folikel telur ayam kampung (Gallus domesticus). Hewan yang digunakan dalam penelitian ini adalah 15 ekor ayam kampung betina umur 16 bulan dengan berat badan berkisar 1,2-1,7 kg dan dibagi dalam 2 kelompok perlakuan. Masing-masing kelompok perlakuan terdiri atas 5 ekor ayam kampung. Kelompok I (P0) sebagai kontrol diberi pakan komersil 324-2 sebanyak 100 g/ekor/hari dan Kelompok II (P1) diberi pakan komersil sebanyak 85 g + ampas kedelai non fermentasi sebanyak 10 g/ekor/hari, dan Kelompok III (P3) diberi pakan komersil sebanyak 85g + ampas kedelai fermentasi sebanyak 10 g/ekor/hari, dan air minum diberikan secara adlibitum. Masing-masing kelompok diberi perlakuan selama 30 hari berturut-turut. Pada hari ke-31, ayam dibedah untuk melihat jumlah folikel telur pada masing-masing kelompok perlakuan. Rata-rata (±SD) jumlah folikel telur pada P1 dan P2 berturut-turut adalah 15±27,5 dan 23,2±16,7 folikel. Hasil penelitian menunjukkan bahwa jumlah folikel telur ayam kampung yang diberi ampas kedelai fermentasi lebih tinggi dan berbeda nyata (P<0,05) dari kelompok yang diberi ampaskedelai nonfermentasi
The aim of the research was to prove that the different feed forms affects the performance and carcass production. In total 240 New Lohmann MB 202 day-old chickens were randomly divided into five groups of treatment for 35 days of rearing period. There were 6 replications with 8 birds per pen. The chickens were fed starter feed at 1-21 days and finisher feed at 22-35 days with different feed forms: mash-mash (MM), mash-crumble (MC), mash-pellet (MP), crumble-crumble (CC), and crumble-pellet (CP). The data were obtained and statistically analyzed by ANOVA, then followed by Duncan’s New Multiple Range Test. Feed form did not give any effect to feed consumption and weight gain but it affected feed conversion (P>0.05). MP kept the highest rate of feed conversion by the end of rearing period. Carcass yield showed that various feed form on days 0-21 did not affect carcass percentage of broiler chickens. The birds which ate pelleted feed on days 22-35 have higher (P>0.05) carcass weight than those consumed mashed and crumbled feeds. It is concluded that chicken fed with mash-pellet feed had the best feed conversion. Besides, the birds which ate pelleted feed on days 22-35 had highest carcass weight.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
