Abstract

UTILIZATION EFFECT OF COCONUT OIL IN RATION ON BODY WEIGHT, PERCENTAGES OF CARCASS AND ABDOMINAL FAT IN SUPER NATIVE HENS. This study was conducted to evaluate utilization effect of coconut oil in ration on body weight, percentages of carcass and abdominal fat in super native hens. This study was involving hundred unsexed super native hens at ages of eight weeks with the average initial body weight of 862.24 g ± 44.13 g. The treatments were ration without coconut oil (CO) utilization (R0), ration of 99.5% basal added with 0.5% CO (R1), ration of 99% basal added with 1% CO (R2), ration of 98.5% basal added with 1.5% CO (R3), and ration of 98.0% basal added with 2.0% CO (R4). The completely randomized design was applied as design with five treatments consisted of five replications at each treatment. Each experimental unit was put four heads of super native hens. The significant treatments were tested by Duncan’s test. Variables measured were life body weight, slaughter body weight, carcass weight and carcass percentage as well as abdominal percentage. Results showed that utilization effect of coconut oil in ration had the same effects on percentages carcassand abdominal fat, but had significant effect on life body weight and carcass weight. Therefore, it was concluded that utilizatilization of coconut oil up to 2 percents in ratio increased life body weight and carcass weight. Keyword: carcass weight, coconut oil, super native chicken.

Abstract

EFFECT OF TOMATOES STARCH (Solanum lycopersicum l) ON INTERNAL EGG QUALITY OF LAYING CHICKEN. This research has been done to determine the effect of tomatoes starch on the internal egg quality of laying chicken. The material used in this study was a 100 laying hens aged 36 weeks with the following treatments P0: basal ration without tomatoes startch; P1: 98% of basal ration + 2% of tomatoes starch: P2; 96% of basal ration + 4% tomatoes starch; P3: 94% of basal ration + 6% of tomatoes starch; P4: 92% of basal ration + 8% of tomatoes starch. Research design used was the completely randomized design (CRD) with 5 treatment and 5 replications. Duncan's multiple range test was used for further test. Variables were observed during the study include egg yolk index, yolk color, and Haugh unit (HU). The results showed that the addition of tomatoes in the diet has no significant effect (P> 0.05) on egg yolk index and haugh units (HU), but highly significant effect (P <0,01) against the color of egg yolks. Based on the research results obtained, it can be concluded that the addition of tomatoes starch in ration as much as 8% will provide a good response to the effect of egg yolk index, Haug units (HU), and yellow egg of laying chicken. Keywords :Laying Chicken, Internal Egg Quality, Tomatoes Starch.

Abstract

SUBSTITUTION OF SOME RATION WITH COCONUT OIL ON THE PERFORMANCE OF LAYING SUPER NATIVE CHICKEN. The pupose of the research is to knowing the substitution of some ratio with coconut oil on the performance of laying super native chicken. this research already implemented during 8 weeks. The material used in this study was a 80 laying hens super native chicken aged 5 month. The research design used was the completely randomized design (CDR) with 5 treatment and 4 replications. Tukey test was used for further test. Treatments were formulated as follow : R0 = 100% control diet + 0% Coconut Oil (CO); R1 = 99.5% control diet + 0.5% CO; R2 = 99% control diet + 1% CO; R3 = 98.5% control diet + 1.5% CO; R4 = 98% control diet + 2% CO. The result showed that applying the coconut oil until 2% giving increase for egg production and giving the same effect for feed consumtion and feed conversion.Keywords : laying super chicken native, coconut oil.

Abstract

Penelitian ini bertujuan untuk menganalisis faktor sosial ekonomi apa saja yang mempengaruhi minat pemuda dalam beternak sapi sehingga dapat mendorong minat mereka untuk beternak sapi sekaligus meningkatkan produktivitas ternak sapi dan pengembangan industri sapi potong di wilayah Kabupaten Minahasa Tenggara. Penelitian  dilaksanakan di Kabupaten Minahasa Tenggara dimana sampel lokasi dipilih secara purposive di Kecamatan Belang dan Kecamatan Tombatu Timur sebagai Kecamatan dengan populasi sapi potong terbanyak yaitu masing masing 888 ekor dan 678 ekor. Sebanyak 106 orang pemuda yag terdiri atas 37 orag yang beternak sapi dan 69 orang tidak beternak sapi dan  berumur 16-30 tahun dipilih secara acak sebagai sampel responden   dari 265 populasi pemuda yang beternak sapi dan yang tidak beternak sapi dengan menggunakan formulasi dari Slovin. Analisis data menggunakan model regresi linier berganda dimana variabel minat pemuda beternak sapi potong dan variabel yang mempengaruhinya di ukur dengan menggunakan skala likert berjenjang  satu sampai tiga. Hasil penelitian menunjukkan bahwa minat pemuda beternak sapi potong di Kabupaten Minahasa Tenggara, Indonesia dipengaruhi oleh faktor sosial ekonomi seperti persepsi terhadap pendapatan,  lingkungan masyarakat, status sosial dan pemilikian lahan pertanian untuk tanaman pakan ternak sedang kan faktor lingkungan keluarga tidak berdampak  signifikan terhadap minat pemuda beternak sapi potong.  Karena itu faktor faktor tersebut perlu menjadi perhatian dari pengambil kebijakan di wilayah penelitian agar pemuda yang beternak terus mendapatkan pengetahuan berupa cara beternak sapi potong yang menguntungkan dengan biaya seminimal mungkin sedangkan untuk pemuda yang belum beternak diberikan bantuan bibit sapi potong untuk memulai usahanya yang tentunya diikuti dengan pendampingan untuk mencegah penyalahgunaan ternak sapi oleh pemuda peternak.
