Abstract

Sorghum (Sorghum bicolor L.) is one alternative as a substitute for corn in rations, it is known that the nutrient content of sorghum is not much different from the nutrition of corn. The purpose of this study was to determine the effect of sorghum use as a substitute for corn in the ration on the weight of the carcass part and what percentage of sorghum substitution level had an effect on the weight of the carcass parts. This study used a completely randomized design (CRD) with 5 treatments and 3 replications. In each replication using 3 CP 707 broiler chickens aged 2 weeks with homogeneous body weight. The treatment is R0 (control ration without sorghum use), R1 (ration + 7% use of sorghum), R2 (ration + 14% use of sorghum), R3 (ration + 21% use of sorghum), R4 (ration + 28% use of sorghum). Variables observed were weight of the chest, weight of the wing, weight of the thigh, weight of the back. The results showed that the use of sorghum (Sorghum bicolor L.) as a substitute for corn at all levels had no significant effect on all parts of the carcass of broiler aged six weeks and the level of use of 21% sorghum tended to increase the weight of the carcass parts.

Abstract

Sprouts waste is a potential source of poultry feed and its availability is quite a lot in the market. The purpose of this study was to determine the effect of giving fermented bean sprouts flour in the ration of 5 weeks old male quail on the weight of non-carcass grower-finisher phase, and to determine the fermentation level of bean sprouts flour waste in the ration affecting the non-carcass weight of quail. The study was conducted using a completely randomized design (CRD) with 4 treatments and 4 replications. Each replication consisted of 3 male quail, so the number of male quails used was 48. The treatments applied in this study were as follows rations without fermented bean sprouts flour as a control and rations containing fermented bean sprouts waste flour 5%, 10%, and 15%. The parameters observed were blood weight, reed, legs, head, and neck. The data obtained were analyzed for variance. From the results of the study that the provision of fermented bean sprouts waste flour in the commercial ration of male quail in the grower-finisher phase showed insignificant differences (P> 0.05) on blood, reeds, legs, head, and neck, except for intestinal weight. real (P <0.05) at the 15% level. From this research, it can be concluded that giving tougeh waste flour has no effect on the non-carcass grower-finisher phase

Abstract

Penelitian ini bertujuan untuk mengetahui kualitas terbaik antara tiga jenis rumput yaitu rumput Pakchong, rumput Zanzibar, dan rumput Biograss Agrinak pada interval pemotongan yang berbeda-beda yakni pada umur pemotongan 50 hari (U1), 60 hari (U2), dan 70 hari (U3). Metode yang digunakan dalam penelitian ini menggunakan Rancangan Acak Kelompok (RAK) pola Faktorial dengan dua faktor. Percobaan dilakukan dengan ulangan 3 kali sehingga didapatkan 9 kombinasi. Adapun variabel pada penelitian ini yaitu Bulk dencity, Daya Serap (Water Regain capacity), Daya Larut (Water Sulobility), Energi Bruto (Gross Energy), Total Degestible Nutrien (TDN). Rumput Pakchong berbeda nyata (P<0,05) paling tinggi pada bulk dencity, daya larut air (Water solubility), energi bruto (Gross energy), dan TDN (Total Digestible Nutrient) dibandingkan rumput Zanzibar dan rumput Biograss Agrinak. Umur pemotongan berpengaruh nyata (P<0,05) terhadap kualitas fisik (Bulk density) dan berpengaruh sangat nyata (P<0,01) terhadap Energi Bruto (Gross energy), pada pemotongan umur 60 hari paling tinggi. Interaksi antara jenis rumput dan umur pemotongan hanya terjadi pada variabel pengamatan daya larut air (Water solubility) tertinggi pada kombinasi perlakuan rumput Pakchong dengan umur pemotongan 70 hari (R1U3), dan variabel TDN tertinggi pada kombinasi perlakuan rumput Zanzibar dengan umur pemotongan 50 hari (R2U1).

Abstract

Kebutuhan produk makanan bergizi terutama produk makanan asal hewani saat ini terus mengalami peningkatan. Untuk mencapai produktivitas ini harus di dukung oleh pakan yang berkualitas salah satunya memanfaatkan limbah kulit nanas terfermentasi. Tujuan dari penelitian ini untuk mengetahui pengaruh pemberian tepung kulit nanas terfermentasi terhadap komposisi fisisk karkas ayam kampung super umur 10 minggu. Rancangan yang digunakan dalam penelitian ini adalah Rancangan Acak Lengkap (RAL) dengan 5 perlakuan dan 3 ulangan. Adapun perlakuan yaitu N0= Ransum tanpa kandungan tepung kulit nanas terfermentasi, N1= Ransum mengandung 5% tepung kulit nanas terfermentasi, N2= Ransum mengandung 10% tepung kulit nanas terfermentasi, N3= Ransum mengandung 15% tepung kulit nanas terfermentasi, N4= Ransum mengandung 20% tepung kulit nanas terfermentasi. Hasil penelitian menunjukan bahwa tidak terjadi pengaruh yang signifikan (P>0,05) kecuali pada perlakuan N0 berbeda nyata (P<0,05) dengan penambahan kulit nanas terfermentasi dalam ransum terhadap komposisi fisik karkas ayam kampung super 10 minggu. Pemberian tepung kulit nanas terfermentasi pada level 5% menunjukan hasil rataan yang paling baik terhadap komposisi fisik karkas ayam kampung super umur 10 minggu kecuali pada perlakuan N0 berbeda nyata. Dari hasil penelitian dapat disimpulkan bahwa Pemberian tepung kulit nanas terfermentasi dalam ransum berpengaruh tidak nyata terhadap komposisi fisik karkas (berat daging paha, berat kulit paha, berat daging dada, berat tulang dada, berat kulit dada kecuali berat tulang paha pada perlakuan N0 berbeda nyata) ayam kampung super 10 minggu.

Abstract

The increasing demand for broiler chickens occurs because the shift in people's consumption patterns from food sources of vegetable protein to food sources of livestock protein is expected to continue to increase and continue in the future. One of the factors that can influence the success of broiler chicken production is external factors, where external factors include chicken seeds (DOC), death/mortality rates, feed, labor and marketing. The aim of this research is to find out whether external factors of breeders have an influence on broiler chicken production in Gianyar Regency, Bali Province and to find out what indicators of external factors of breeders have the most dominant influence on broiler chicken production in Gianyar Regency, Bali Province. The population of this study were all broiler chicken breeders who live in Gianyar Regency, Bali Province. The number of samples for this research was 57 samples taken using the purposive random sampling method. The design used in this research was a survey method. In this research, the data collection method used was a questionnaire. Data collection was carried out by means of interviews, observations and questionnaires. The collected data was analyzed using qualitative descriptive analysis. The research results show that from the T test results, DOC (X1), Feed (X3), Labor (X4), and Marketing (X5) which are indicators of the External Factor variable (X) are proven to have no significant effect on the Broiler Chicken production variable ( Y). And the mortality rate indicator (X2) is the most dominant indicator and has a significant effect on Broiler Chicken Production (Y).
