Judul: Egg Quality Appearance of Medium Type Layer Hens in Different Feeding Time and Protein Levels.
Abstrak: Domesticated fowls, in particular the layer hens, play an important as one of the egg and meat producing fowls. The primary commodity produced by these layers composes highly nutritional value and are considered as a highly demanding commodity. This research was conducted at Housing-B of the Poultry Field Laboratory, Faculty of Animal Production, Bogor Agricultural University. The research used 162 hens of Isa Brown medium type layer, 20 weeks old which were raised at individual cages constructed completely with feeder and drinker. The aim of this research was to observe the egg quality of the Isa Brown medium type layer assigned to different feeding times and protein levels. The research used 3x3 Factorial Completely Randomized Design with three feeding time (morning at 08.00, afternoon at 18:00, and dawn at 04.00); and three different protein levels (12, 15 and 18%), treatment consisted of three replicates. Each replicate consisted of six birds. Ration was fJrmuiated iso-caloric energy (2650 Kcal/kg). The variables observed were external egg quality which consist of egg weight, entirety, translucency, egg index, shell thickness, and specific gravity; and internal egg quality which consist of Hallgh Unit, egg yolk color, and yolk and albumen weight. The result showed that here was not effect of interaction between time of feeding and protein level on the observed parameters Feeding time had significant effect on shell thickness. The protein level treatml:uts showed significantly (p<=0.05)on egg weight, shell thickness, egg yolk color, yolk and albumen weight. Based on the cleaness entirely, almost all of the eggs colected were considered clean and undamaged. Key words: feeding time, protein level, egg quality, layer medium hens.

Judul: Organic Mineral Mixed Supplementation In The Feed Of Isa Brown Laying Hens On The Performance And Quality Of Eggs Aged 68-75 Weeks
Abstrak: Penelitian ini dilakukan untuk mengevaluasi suplementasi campuran mineral organik dalam pakan terhadap performa dan kualitas telur ayam Isa brown umur 68-75 minggu. Penelitian ini menggunakan 2033 ayam petelur strain Isa brown berumur 68 minggu sampai 75 minggu. Dalam pengujian kualitas, 24 sampel digunakan. Penelitian ini menggunakan 2 perlakuan dan 12 ulangan. Metode yang digunakan adalah Rancangan Acak Lengkap (RAL) yaitu: T0 (pakan kontrol), dan T1 (pakan kontrol + suplementasi campuran mineral organik). Variabel yang diamati adalah kualitas telur (warna kerabang, kekuatan kerabang, ketebalan kerabang, dan haugh unit) dan performa yang diamati (konsumsi pakan, produksi telur, bobot telur, konversi pakan, dan produksi massa telur). Data dianalisis menggunakan uji paired sample T-test dan uji wilcoxon dengan taraf 5%. Hasil penelitian menunjukkan bahwa suplemen campuran mineral organik berpengaruh nyata (P<0,05) terhadap produksi telur ayam, konversi pakan, produksi massa telur, warna cangkang, ketebalan cangkang, dan kekuatan cangkang, tetapi tidak terdapat perbedaan nyata (P>0,05) terhadap bobot telur, konsumsi pakan, dan haugh unit. Dapat disimpulkan bahwa penggunaan suplementasi campuran mineral organik dapat memberikan hasil yang baik pada performa dan kualitas telur ayam sehingga dapat diaplikasikan., This study was conducted to evaluate organic mineral mixed suplementation In the feed of Isa brown laying hens on the performance and quality of eggs aged 68-75 Weeks. This study used 2033 laying hens strain Isa brown aged 68 weeks to 75 weeks. In quality testing, 24 samples were used. This study used 2 treatments and 12 replications. The method used was Completely Randomized Design (CRD) were: T0 (control feed), and T1 (control feed + organic mineral mixture supplementation). The observed variables were egg quality (shell color, shell strength, shell thickness, and haugh unit) and observed performance (feed consumption, egg production, egg weight, feed conversion, and egg mass production). Data were analyzed using paired sample T-test and wilcoxon test with a level of 5%.The results showed that organic mineral mix supplement had a significant effect (P<0,05) on hen day production, feed conversion, egg mass production, shell color, shell thickness, and shell strength, but there was no significant difference (P>0,05) on feed consumption, egg weight, haugh unit. The results of this study can be concluded that the use of organic mineral mixture supplementation can provide good results on the performance and quality of chicken eggs so that it can be applied.
