Abstract

THE GROWTH OF PERFORMANCE “BANGKOK” CHICKEN AT THE STARTER PHASE GIVEN FEED IN LEVELS OF DIFFERENCE PROTEIN. This study was conducted to evaluate the levels of protein in ration affecting consumption, average daily gain, feed conversion and mortality of “Bangkok” chicken at the starter phase. Birds used in this study were 36 chicken at the age of 2 weeks old. Treatments in this study were rations with protein levels of 18 percents (Ration A), 20 percents (Ration B), and 22 percents (Ration C).Variables observed were feed consumption (g/h/d), Average daily gain (g/h/d), feed conversion and mortality (percents). Method of completely randomized design were applied in this study using 3 treatments with 6 replications at each treatment. Each treatment and replication was filled 2 chicken of “Bangkok” strain. Results of this study showed that protein levels of 18 to 22 percents in the diets did not affect feed consumption, average daily gain, feed conversion and mortality. Therefore, it can be concluded that the protein levels of 18 to 22 percents in the diets had the same responses in growing performance of “Bangkok” strain at starter phase.Kata Kunci:“Bangkok” strain chicken, growing performance, protein levels.

Abstract

ABSTRACT EFFECT OF SUBSTITUTION OF FISH MEAL WITH MAGGOT (Hermetia illucens) IN THE DIETS ON BROILER CHICKEN PERFORMANCE. Maggots (maggot meal) have been widely studied as a good alternative to fish meal in broiler chicken and pigs. The present study was designed to elaborate the effect of substituting fish meal with maggot (Hermetia illucens) meal in the diets on feed efficiency of broiler chicken. Eighty day old chicks (DOC) broiler chicks were placed in battery cages and were assigned to each dietary treatment (5 treatments) which was replicated four times in a completely randomized design (CRD) arrangement anddatawere all submitted to the ANOVA procedure. Differences were considered significant at P< 0.05.  Diets were formulated to meet or exceed starter and finisher broiler requirements as recommended by NRC (1994). Treatment diets were formulated as follow: R0 =  100.0% fish meal (15.0% in the diet) + 0% maggot meal (0% in the diet); R1 =  75% fish meal (11.25% in the diet) + 25.0% maggot meal (3.75% in the diet); R2 = 50.0% fish meal (7.5% in the diet) + 50.0% maggot meal (7.5% in the diet); R3 = 25.0% fish meal (3.75% in the diet) + 75.0% maggot meal (11.25% in the diet); and R4 = 0% fish meal (0% in the diet) +100.0% maggot meal (15.0% in the diet). Parameters measured were: feed consumption, daily gain, and feed efficiency ratio. Research results showed that feed consumption, daily gain, and feed efficiency ratio of starter and finisher broiler chicks in the present study were significantly decreased as maggot meal substituted fish meal at the level of 100% or 15.0% in the diet (R4). It can be concluded that maggot (Hermetia illucens) mealcould replace fish meal up to 75.0% or 11,25% in the diet without any negative effects on feed efficiency ratio of broiler chicken. Keywords: Fish meal, Maggot (Hermetia illucens) meal, Broiler chicken, Feed efficiency ratio

Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh persentase carboxy methyl cellulose (CMC) terhadap waktu leleh, pH, dan sifat sensoris es krim probiotik. Es krim probiotik menggunakan bakteri probiotik yakni Lactobacillus acidophilus, Lactobacillus bulcariccus, dan Streptococcus thermophiles sebagai starter. Bahan-bahan lain yang digunakan adalah: CMC, susu UHT, telur, agar-agar, whipped cream dan susu bubuk serta gula. Penelitian ini menggunakan rancangan acak lengkap (RAL) dengan 6 perlakuan dan 5 ulangan untuk pengujian waktu leleh, dan pH, sedangkan untuk pengujian sensoris (warna, aroma, tekstur, dan cita rasa) es krim probiotik dengan menggunakan uji Skala Hedonik terhadap 45 panelis tidak terlatih. Perlakuan yang di gunakan pada penelitian ini antara lain : tanpa perlakuan P0 : Es Krim Probiotik + 0% CMC, P1 : Es Krim Probiotik + CMC 0,4% , P2 : Es Krim Probiotik + CMC 0,8%, P3 : Es Krim Probiotik + CMC 1,2%, P4 : Es Krim Probiotik + CMC 1,6%, P5 : Es Krim Probiotik + CMC 2,0%. Hasil analisis keragaman menunjukkan bahwa penggunaan carboxy methyl cellulose (CMC) memberikan respon berbeda tidak nyata terhadap sifat sensoris warna, tekstur dan aroma es krim probiotik, tetapi berbeda nyata terhadap waktu leleh, pH, dan sensoris (citarasa) es krim probiotik. Untuk variable yang berbeda nyata dilanjutkan dengan uji BNJ. Berdasarkan hasil pada penelitian yang dilakukan disimpulkan bahwa es krim probiotik penggunaan persentase CMC 1,2% merupakan perlakuan terbaik terhadap  uji waktu leleh, pH dan sensoris (citarasa) es krim probiotik.Kata Kunci : CMC, es krim probiotik, waktu leleh, pH, dan cita rasa
