Abstract

THE EFFECT OF FEED RESTRICTION ON THE PERFORMANCE OF BROILERWITH DIFFERENT STRAINS. This study aims to measure the growth performance of broilers with different strains through a feed restriction pattern at the beginning of growth (starter). This study used 72 day-old broilers consisting of 36 Cobb strains and 36 Lohman strains selected from each of them. -each 100 heads to get almost the same body weight obtained successively from PT. Charoen Phokphand and PT. Japfa Comfeed Indonesia. The design used was a completely randomized design (CRD) with a 2x4 factorial pattern with 3 replications. The A factor is the difference in strains (A1 = Lohman, A2 = Cobb), while the B factor is the time of feed restriction (B0 = no feed restriction, B1 = feed restriction starts on day 8, B2 = Feed restriction starts on day 11, B3 = Feed restriction begins On day 14. There were 8 treatment combinations. Feed restriction was carried out as much as 20 percent. The measured variables were feed consumption, body weight gain, and feed conversion. The results of the analysis of variance showed that there was a significant interaction (P <0.05) between the strains different from the start of the feed restriction on feed consumption and body weight gain, while the feed conversion variable did not show a significant interaction (P> 0.05) .Tukey's test results showed that the feed consumption in the combination of Lohman strain treatment with limitation time of 11 days (98.95) is not significantly different (P> 0.05) with the combination of A1B0 (97.52), A2B3 (91.34), but A2B0 (95.36) is significantly different (P <0.05) is higher with all combinations treatment. The results of the analysis of variance showed that there was a significant interaction (P <0.05) between factor A and factor B. The results of the Tukey test showed that the treatment of A1B2 (54.63) was not significantly different (P> 0.05) with A1B1 (51, 70), thus with treatment A2B0 (48.13), treatment A1B0 (49.93) with A2B1 (49.13), A2B3 (49.12), A2B0 (48.13) and A2B2 (47.21) . Lohman strain broiler and 20% restriction with restriction time starting on the eleventh day gave the best performance response. Keywords: Strain, feed restriction, time limitation

Abstract

Tujuan penelitian ini untuk mengetahui kualitas fisik dan kimia produk salami ayam petelur afkir menggunakan tepung sorgum (Sorghum bicolor L.) sebagai bahan pengisi dalam pengolahan salami. Penelitian dilaksanakan menggunakan Rancangan Acak Lengkap (RAL) dengan 5 perlakuan P0 (0%), P1(2,5%), P2 (5%), P3 (7,5%) dan P4 (10%) setiap perlakuan diulang 4 kali. Parameter yang diukur sifat fisik meliputi daya mengikat air, susut masak dan  keempukan;   pengujian kimia/proksimat yang terdiri dari kadar air, kadar protein, kadar lemak, dan karbohidrat. Data hasil penelitian diolah menggunakan analisis sidik ragam dan dilanjutkan dengan  Uji Tukey. Berdasarkan hasil penelitian diperoleh bahwa mutu kimia seperti kadar air 46,56%, protein 16,08%, lemak 22,03% dan karbohidrat 13,89%; mutu fisik seperti susut masak menurun dari 24,77% - 19,63%; DIA meningkat dari 26,03 % - 36,44%; keempukan meningkat dari 136,75% - 181,75%. Kesimpulan dari penelitian ini adalah penggunaan tepung sorgum (Sorghum bicolor L.) sebagai bahan pengisi pembuatan salami ayam petelur afkir sebanyak 10%, bakteri asam laktat 2% dan yeast 2%.                                                                      Kata kunci: Tepung sorgum, ayam petelur afkir, salami

Abstract

A study was aimed to evaluated the effect of partial replacement of corn with goroho banana stem mealon broiler chicken performans. The study was conducted at Faculity of Animal Science, University of Sam Ratulangi Manado. Using sixty three weeks broiler CP 707. Research used a complete randomized design, consisting of 4 treatmenst and 5 replications, ie  Ro : ration without goroho banana stem meal, R1 : 5% corn meal replaced with goroho banana stem meal, R2 : 10% corn meal replaced with goroho banana stem meal , R3 : 15% corn meal replaced with goroho banana stem meal . The variables which measured were : ration consumption, body weigth gain and ration conversion. The data were analyzed using analysis of variance ( Anova), and any significant differences were further test using Tukey test. The treatment was non significantly  diference ( P > 0,05) on ration consumption, but significantly difference ( P > 0,05 ) on body weight gain and ration conversion. The results of analysis of variance showed that the was non significantly difference (P>0.05) on ration consumption, while the addition of body weight and ration conversion were significantly difference ( P> 0,05 ). The Tukey test showed that the  body weight gain of R0 non significantly diference  ( P > 0,05 ) to the treatment  of R1 however R0  was significantly diference to R2 and R3, while the treatment of R1 with R2 and R1 with R3 showed significantly difference (P>0.05 )Based on this study, it could be conduded the Goroho banana stem meal (musa acuminata, sp) could substitute a part of corn up to 5% which made a better performance for broiler chicken Keywords : Broiler, Goroho banana steam meal, broiler performans

Abstract

DETERMINATION OF NITROGEN RETENTION AND METABOLIC ENERGY OF BANANA PEELS (Musa paradisiaca) FERMENTATION WITH Rhizopus oligosporus ON BROILER RANSOM. Banana peel is a waste that has the potential to be used as feed because it is abundant and has the nutrients needed by livestock. This study aims to determine protein consumption, nitrogen retention value (RN) and nitrogen-corrected metabolic energy (AMEn) value of broiler rations containing unfermented plantain peel flour and fermented broiler rations with Rhizopus oligosporus mold. This research was conducted using 20 broilers of strain Arbor Acres CP 707 aged 5 weeks. The design used was Student's t-test which consisted of 2 treatments, each treatment consisting of 10 broilers as replications. The rations used in this study were rations containing plantain peel flour without fermentation and rations containing fermented plantain peel flour with Rhizopus oligosporus mold. The results of the analysis of diversity showed that the treatment between no fermentation and fermentation was significantly different for protein consumption (P <0.05), nitrogen retention was significantly different (P <0.05) and the value of metabolic energy was significantly different (P <0.05). The T-Student test results for the protein consumption value of nitrogen retention values showed that the treatment without fermentation was 63.59% and 71.87% fermented products with Rhizopus oligosporus mold. The metabolic energy values in the treatment without fermentation were 2336.6 Kcal / kg and 2732.4 Kcal / kg in fermentation products with Rhizopus oligosporus mold. Based on the results of this study it can be concluded that the use of fermented plantain peel products with Rhizopus oligosporus in broiler rations can increase protein consumption, nitrogen retention, and metabolic energy of broiler chickens.Key words: plantain peel, fermentation, Rhizopus oligosporus, broiler chicken.
