The present study was designed to investigate the influence of Moringa oleifera on Laying Hens Performance, β-carotene, cholesterol, and minerals contents in egg yolk. Two hundred and forty 30 weeks of healthy laying hens with homogeneous body weight in a complete randomized design with four treatments and 6 replications. Laying hens were randomly divided into four groups: M0: diets without administration of Moringa oleifera leaves, M1: diets with 2% Moringa oleifera leaves; M2: diets with Moringa oleifera leaves 4%; and M3: diets with 6% Moringa oleifera leaves, respectively. Each treatment consisted of six replication cages with 10 birds randomly assigned to each cage. This study showed that administration of the Moringa leaves powder were increased significantly different on egg productions, egg mass, feed efficiencies, yolk color, shell thickness, Mg and Ca contents in eggshell, but not the efficiency of feed consumption. The administration of 2-6% Moringa leaves powder in diets results in significantly lower yolk cholesterol contents. It was concluded that supplementation of 4-6% Moringa leaves powder in diets, increased egg production, egg mass, feed efficiencies, yolk color, shell thickness, β-carotene, Mg and Ca contents in the yolk, but decreased yolk cholesterol contents in laying hens.

Selection program applied to improve the animal genetic potential.  This program can be carried out based on the performance and breeding values ??of the economic trait of each individual.  The research was carried out for 5 month (from May until September 2018).  The purpose of this study was to find out the superior Bali bull by determining of chest girth male Bali cattle. This study used purposive random sampling method. The number of male Bali cattle with incisor of I0,I1,I2 used in this study were 147,29,19 heads respectively. Performance test was calculated by formula of BV = h2 ( Pi – P ) (Hardjosubroto, 1994).  The results showed that the average of chest girth male Bali Cattle for I0, I1 and I2 were 135,65±16,98cm; 159,57±13,75cm and 166,26±19,94cm respectively. Based on the breeding value, male Bali cattle coded BK030 with I1 and BK101 with I2 were recommended as a superior Bali bulls because of  their highest ranking.

Penelitian ini bertujuan untuk mempelajari pengaruh penggunaan pollard terfermentasi oleh ragi tape terhadap produksi telur ayam Lohmann Brown umur 42-50 minggu. Rancangan yang digunakan adalah rancangan acak lengkap (RAL) dengan tiga perlakuan dan enam kali ulangan dan setiap ulangan menggunakan dua ekor ayam Lohman Brown umur 42 minggu. Ransum yang digunakan selama penelitian mengandung protein kasar 17% dan energi metabolis 2750 kkal/kg. Ransum tanpa pollard (A) sebagai ransum kontrol, ransum dengan penggunaan 15% pollard (B), dan ransum dengan 15% pollard terfermentasi oleh ragi (C). Ransum dan air minum diberikan ad libitum. Variabel yang diamati, yaitu konsumsi ransum, berat telur total, berat telur rata-rata, jumlah telur, tebal kulit telur, berat jenis, warna kuning telur, efisiensi penggunaan ransum, dan kadar kolesterol telur. Hasil penelitian menunjukkan bahwa penggunaan 15% pollard terfermentasi oleh ragi (perlakuan C) ternyata tidak berpengaruh nyata (P>0,05) terhadap konsumsi ransum, berat telur, hen-day production, warna kuning telur, dan FCR dibandingkan dengan kontrol. Sebaliknya, secara nyata (P<0,05) menurunkan kadar kolesterol telur ayam. Penggunaan 15% pollard ternyata secara nyata (P<0,05) meningkatkan konsumsi ransum. Akan tetapi secara nyata (P<0,05) menurunkan efisiensi penggunaan ransum, hen-day production, dan tebal kulit telur dibandingkan dengan kontrol. Dari hasil penelitian ini dapat disimpulkan bahwa penggunaan 15% pollard dalam ransum ternyata menurunkan produksi telur, dan sebaliknya setelah mengalami fermentasi oleh ragi tape nyata memberikan hasil yang sama dengan kontrol serta mampu menurunkan kadar kolesterol telur ayam Lohmann Brown umur 42-50 minggu.

Seleksi merupakan salah satu tindakan yang dilakukan untuk meningkatkan mutu genetik suatu populasi ternak.Respon seleksi yang terjadi tergantung pada intensitas seleksi, heritabilitas dan simpangan baku sifat yang diseleksi.Simpangan baku sifat atau performans ternak yang diseleksi akan menunjukkan keragaman (variasi) sifat tersebutdalam populasi yang dikenal dengan koefisien variasi (keragaman). Penelitian ini bertujuan untuk mengetahuikoefisien keragaman dan efisiensi respon seleksi yang terjadi, bila seleksi dilakukan pada dimensi tubuh (panjangbadan, tinggi gumba dan lingkar dada) yang didasarkan intensitas seleksi dan estimasi heritabilitas yang samaterhadap semua dimensi tubuh yang diukur. Penelitian ini dilakukan secara purposive random sampling padalima kelompok ternak di lima kecamatan di kabupaten Jembrana. Jumlah induk sapi bali yang digunakan dalampenelitian ini sebanyak 275 ekor. Variabel yang diukur adalah panjang badan, tinggi gumba dan lingkar dada. Hasilpenelitian menunjukkan rataan panjang badan, tinggi gumba dan lingkar dada sapi bali induk di lokasi tersebutberturut-turut 117,19±8,84cm; 115,12±6,35cm dan 165,43±12,54cm dengan koefisien keragamannya berturut-turut7,54%; 5,52% dan 7,58%, sedangkan respon seleksinya berturut-turut 0,60cm; 0,76cm dan 1,25cm. Kesimpulanyang dapat diambil dari hasil penelitian ini adalah respon seleksi yang paling efektif untuk peningkatan mutugenetik dimensi tubuh sapi bali betina adalah terhadap lingkar dadanya. Kata kunci: sapi bali, seleksi, respon seleksi

The objective of this research was to determine the ration containing dragon fruit peel meal fermentation for productivity and intestinal profiles of broiler as been implemented for 4 weeks. The study design used is completely randomized design (CRD) where used with 3 treatment s and 5 replications of each has 10 birds. A number of 150 of one weeks age broiler were used in this experiment. The treatments were R0= control diet without dragon fruit peel meal fermentation, R1= diet with 5% fermentation dragon fruit peel meal; RD2= diet with 7% fermentation dragon fruit peel meal. The variables studied were: feed consumption, feed conversion, final body weight, body weight gain, intestinal profile. The results of this study indicate that feed consumption, feed conversion, weight gain, carcass weight, carcass percentage, intestinal profile were not significant (P> 0.05) effect after treatments of R0, R1, R2 but feed conversion ratio (FCR) and final body weight for R2 treatment has a significant effect (P0 <0.05). It can be concluded that the use of 3% -7% fermented dragon fruit peel meal on the ration did not a significant effect on broiler productivity and intestinal profile but the treatment with 7% fermented dragon fruit skin flour was significantly different to the final body weight and FCR.
