Abstract

ABSTRAK. Tujuan penelitian ini untuk mengukur seberapa besar pengaruh minyak ikan yang sudah terenkapsulasi terhadap kolesterol darah dan performa pada Domba. Penelitian telah dilakukan di Sub Unit Pelayanan Pengembangan Pembibitan Ternak Domba dan Kambing (SUPPPTDK) Bunihayu, Subang pada tanggal 20 Januari 2020 sampai 27 Maret 2020. Sebanyak 18 ekor domba Ekor Tipis jantan dengan bobot 15,990,98 kg dialokasikan ke dalam 3 perlakuan secara acak. Domba tersebut diberi ransum perlakuan yang disuplementasi dengan mikroenkapsulasi minyak ikan sebanyak 0% (P0), 2,5% (P1), dan 5% (P2). Data yang terkumpul dilakukan analisis ragam dan bila hasil berbeda nyata maka dilanjutkan dengan uji Duncan. Hasil menunjukkan bahwa mikroenkapsulasi minyak ikan dapat menurunkan kolesterol darah (P0,05), namun tidak berpengaruh nyata terhadap pertambahan bobot badan, konsumsi dan konversi ransum (P0,05). Penurunan kadar kolesterol terjadi pada kelompok domba dengan perlakuan mikroenkapsulasi sebanyak 2,5% (P1) dan mikroenkapsulasi 5% (P2). Kadar kolesterol darah masing-masing perlakuan berturut-turut adalah 100,70 mg/dl (P0); 96,20 mg/dl (P1); dan 78,76 mg/dl (P2). Rataan yang terbaik pada pertambahan bobot badan, konsumsi bahan kering harian, dan konversi ransum terdapat pada P2 yaitu 63,96 g/hari, 574,13 g/hari, dan 9,08. Hasil penelitian dapat disimpulkan bahwa mikroenkapsulasi minyak ikan dapat menurunkan kolesterol darah, dengan penurunan tertinggi pada pemberian 5%. (The impact of microencapsulation fish oil in feed on blood cholesterols and performance on sheep) ABSTRAK. This study measured the effect of encapsulated fish oil on blood cholesterol and sheep performance. The study was conducted at the Bunihayu Sheep and Goat Breeding Services Bunihayu, Subang on January 20, 2020 to March 27, 2020. A total of 18 male thin-tailed sheep 15.990.98 kg were allocated randomly into 3 treatments. The sheep were given feed supplemented with fish oil microencapsulation of 0% (P0), 2.5% (P1), and 5% (P2). The data were collected and analyzed by analysis of variance and, if the result is significantly different, continued by Duncan's test. The results showed that fish oil microencapsulation decreased blood cholesterol levels (P0.05). However, it did not affect body weight gain, consumption, and feed conversion (P0.05). Decreased levels of cholesterol occurred in the group of sheep with 2.5% microencapsulation (P1) and 5% microencapsulation (P2). Blood cholesterol levels of each treatment were 100.70 mg/dl (P0); 96.20 mg/dl (P1); and 78.76 mg/dl (P2), respectively. Averagely, the highest body weight gain, dry matter intake and feed conversion were found in P2 as much as 63.96 g/day, 574.13 g/day, and 9.08, respectively. The results can be concluded that microencapsulation of fish oil can reduce blood cholesterol, with the highest decrease at the level of 5%.

Abstract

ABSTRACT. Pasundan cattle is currently proposed as a potential livestock to support national meat self-sufficiency program. However, the information regarding their reproductive performance is still very limited. This study was conducted to evaluate the semen production characteristics of Pasundan bull at different body weight. A total of 178 semen samples which were collected from one Pasundan bull were used in this study. The semen collection was done for 31 months and during this period, the body weight of Pasundan bull was classified into 4 categories, namely 400 kg, 400 to 500 kg, 500 to 600 kg, and 600 kg. The results showed that overall mean semen volume, semen pH, sperm concentration, total sperm, individual sperm motility, total motile sperm, post-thawing sperm motility, recovery rate of sperm motility, and frozen semen production were 5.89 ml/ejaculate, 6.69, 1.04 billion/ml, 6.04 billion/ejaculate, 55.75%, 3.40 billion/ejaculate, 40.91%, 58.20%, and 265.11 doses/ejaculate. The difference in body weight significantly affect semen volume (P=0.001), semen pH (P=0.001), sperm concentration (P=0.043), total sperm (P=0.002), individual sperm motility (P0.001), total motile sperm (P0.001), and frozen semen production (P=0.004). There was no significant effect (P0.05) of body weight on post-thawing sperm motility and recovery rate of sperm motility. In conclusion, the semen production traits of Pasundan bull are improved with the increase in body weight up to 500 to 600 kg and remain stable at the body weight of 600 kg.(Karakteristik produksi semen sapi Pasundan pada bobot badan yang berbeda)ABSTRAK. Sapi Pasundan saat ini diajukan sebagai salah satu ternak potensial untuk mendukung program swasembada daging nasional. Akan tetapi, informasi tentang penampilan reproduksinya masih sangat terbatas. Penelitian ini dilakukan untuk mengevaluasi karakteristik produksi semen sapi pejantan Pasundan pada bobot badan yang berbeda. Sebanyak 178 sampel semen yang dikoleksi dari 1 ekor sapi pejantan Pasundan digunakan pada penelitian ini. Penampungan semen dilakukan selama 31 bulan dan pada periode tersebut, bobot badan sapi pejantan Pasundan diklasifikasikan menjadi 4 kategori yaitu 400 kg, 400 to 500 kg, 500 to 600 kg, and 600 kg. Hasil penelitian menunjukkan bahwa rata-rata volume semen, pH semen, konsentrasi sperma, total sperma, motilitas individu sperma, total sperma motil, motilitas sperma post-thawing, nilai recovery rate, dan produksi semen beku adalah 5,89 ml/ejakulat, 6,69, 1,04 miliar/ml, 6,04 miliar/ejakulat, 55,75%, 3,40 miliar/ejakulat, 40,91%, 58,20%, dan 265,11 dosis/ejakulat. Perbedaan bobot badan memberikan pengaruh terhadap volume semen (P=0,001), pH semen (P=0,001), konsentrasi sperma (P=0,043), total sperma (P=0,002), motilitas individu sperma (P0,001), total sperma motil (P0,001), dan produksi semen beku (P=0,004). Di sisi lain, bobot badan tidak memberikan pengaruh (P0,05) terhadap motilitas sperma post-thawing dan nilai recovery rate. Kesimpulannya, karakteristik produksi semen sapi pejantan Pasundan meningkat seiring dengan peningkatan bobot badan hingga 500 sampai 600 kg dan tetap stabil hingga 600 kg.

Abstract

ABSTRACT. Stakeholders and their network place top rank of value chain business and ruled prominent roles in the livestock development sector particularly poultry commodity. The involvement of many stakeholders and other parties is questionable because they perform and shape the market and business chain. The study was done in Manokwari using focus group discussion towards twenty-four various represented individuals, groups and mass organizations. The key queries discussed concerning the introduced background of the organization, shared resources, inter-connectivity amongst actors, intervention and innovation preferences and shared by actors. Stakeholder Network Analysis was employed to run the network and relationship between actors using the Pearson Correlation Coefficient and Hierarchical Clustering Analysis. The finding is that the stakeholders in the poultry farming systems are dominated by private group actors who are working in groups to manage the farms and its value chain process and officially have been under laws. These actors commonly act like positive important stakeholders, who ruled the farms. The threats are real and exist and should be lowering as much as possible to mitigate the turn-back effect. The top five shared resources are access, spaces, time, policy, knowledge and skills. Those resources will stay longer to sustain the strong needs of poultry farms. The relationship of actors is dominated by the ranges of correlation are varying in between negative, neutral to positive. Actors are not delivering the intervention and innovation yet. Actors with low interest and low power should then be promoted to high interest and high power by using aids, guidance, and services from each actor from its value chain and cooperation and farming business. (Pemetaan Pemangku Produksi dan Bisnis Unggas Strategis dan Berkelanjutan Dengan Aplikasi Analisis Jaringan Stakeholder) ABSTRAK. Pemangku kepentingan dan jaringannya menempati peringkat teratas dalam bisnis rantai nilai dan memegang peran penting dalam sektor pengembangan peternakan khususnya komoditas unggas. Keterlibatan banyak pemangku kepentingan dan pihak lain patut dipertanyakan. Penelitian dilakukan di Manokwari dengan menggunakan FGD terhadap dua puluh empat perwakilan individu, kelompok dan ormas. Pertanyaan utama membahas tentang latar belakang organisasi yang diperkenalkan, sumber daya bersama, interkoneksi antar aktor, preferensi intervensi dan inovasi dan dibagikan oleh aktor. Analisis Jaringan Pemangku Kepentingan digunakan untuk menjalankan jaringan dan hubungan dengan menggunakan Koefisien Korelasi Pearson dan Analisis Pengelompokan Hirarkis. Temuannya adalah bahwa para pemangku kepentingan dalam sistem peternakan unggas didominasi oleh pelaku kelompok swasta yang bekerja dalam kelompok untuk mengelola peternakan dan proses rantai nilainya dan secara resmi berada di bawah undang-undang. Aktor ini biasanya bertindak seperti pemangku kepentingan penting yang positif, yang mengatur pertanian. Ancaman itu nyata dan ada dan harus diturunkan sebanyak mungkin untuk mengurangi efek balik. Lima sumber daya bersama teratas adalah akses, ruang, waktu, kebijakan, pengetahuan, dan keterampilan. Sumber daya tersebut akan bertahan lebih lama untuk menopang kebutuhan kuat peternakan unggas. Hubungan antar aktor didominasi oleh rentang korelasi yang bervariasi antara negatif, netral hingga positif. Para pelaku belum melakukan intervensi dan inovasi. Pelaku dengan kepentingan rendah dan kekuasaan rendah kemudian harus dipromosikan menjadi kepentingan tinggi dan kekuasaan tinggi dengan menggunakan bantuan, bimbingan, dan layanan dari masing-masing pelaku dari rantai nilai dan koperasi dan usaha tani.

Variabel fisiologis sapi meliputi suhu rektal (Tr), suhu kulit (Ts), frekuensi pernapasan (RR) dan denyut jantung (HR). Tr dan TS digunakan menghitung suhu tubuh sapi (Tb). Tr dan RR digunakan menghitung Heat Tolerance Coefficient (HTC). Uji beda (t-test) digunakan untuk mengetahui ada tidaknya perbedaan kondisi iklim dan respon fisiologis sapi Pesisir di dataran rendah dan tinggi Sumatera Barat. Hasil penelitian menunjukkan potensi iklim di dataran rendah adalah rerata suhu lingkungan 29,96C, rerata kelembapan 64,22%, rerata THI 79,96 sedangkan potensi iklim di dataran tinggi adalah rerata suhu lingkungan 25,42C, rerata kelembapan 69,48%, rerata THI 74,3. Rerata daya tahan panas sapi di dataran rendah 1,78 dan dataran tinggi 1,82. Kesimpulan penelitian menunjukkan potensi iklim dataran rendah untuk pemeliharaan sapi termasuk zona cekaman panas sedangkan dataran tinggi dalam cekaman ringan. Kondisi fisiologis sapi Pesisir di dataran rendah yang berbeda dengan sapi yang di dataran tinggi adalah suhu rektal, suhu kulit, suhu tubuh dan denyut jantung sedangkan frekuensi pernapasan didapatkan sama di kedua dataran. Daya tahan panas sapi Pesisir cukup baik ditemui di kedua dataran Sumatera Barat.(Microclimate and physiological responses of Pesisir cattle at lowland and highland of West Sumatra) ABSTRACT. This research aimed to investigate the potential of microclimate and physiological responses of Pesisir cattle that are maintained in lowland (Padang City (0-300 m asl)) and highland (Padang Mengatas BPTU ( 600 m asl)) in West Sumatra. The experimental animals were 8 pesisir cattle. The measured variables were abiotic environment and physiological responses of Pesisir cattle. Abiotic environmental measures were ambient temperature (Ta), humidity (RH) and Temperature Humidity Index (THI). Physiological variables were rectal temperature (Tr), skin temperature (Ts), respiratory rate (RR), and heart rate (HR). Tr and Ts were used to determine body temperature (Tb). Tr and RR are variables for calculating Heat Tolerance Coefficient (HTC). To determine whether there are differences in climatic conditions and physiological values in the two regions, the data were analyzed using a t-test. The results showed that climate potential in the lowlands was the average Ta 29.96 C, the average Rh 64.22% with an average THI 79.96 while the potential climate in the highlands was the average Ta 25.42C, the average Rh 69, 48% with a mean THI of 74.3. The average HTC of cattle in the lowlands is 1.78 and the highlands is 1.82. The conclusion showed the climate potential of lowland for raising beef cattle includes heat stress zones, while the highlands there was mild stress. The physiological conditions of Pesisir cattle in the lowlands different from the highlands are Tr, Ts, Tb, and HR while RR is found the same in both plains. HTC of Pesisir cattle is good in both plains of West Sumatera.

Abstract

ABSTRAK. Hati adalah kelenjar terbesar yang terdapat di dalam tubuh dan dapat dianggap sebagai organ pusat dalam pemeliharaan suplai energi. Penelitian ini bertujuan untuk mengetahui histologi, histomorfometri, dan histokimia sebaran glikogen pada hati ayam buras sebelum dan sesudah menetas. Sampel penelitian dibagi menjadi empat kelompok tingkat umur berbeda dan masing-masing kelompok berjumlah enam hati ayam. Hasil penelitian menunjukkan perbedaan nyata (P0,05) pertumbuhan hati ayam buras secara makroskopis. Pada setiap perkembangan sudah terdapat hepatosit berbentuk poligon yang memiliki inti sel bulat di tengah hepatosit, terdapat juga vena central yang dilapisi sel endotel pipih selapis serta didapati sinusoid yang berada diantara hepatosit, dan juga ditemukan Kupffers cell hanya pada hati ayam setelah menetas hari ke-7. Hasil pengukuran diameter vena central hati ayam buras hari ke-7, hari ke-14, hari ke- 20 sebelum menetas dan hari ke-7 setelah menetas berturut-turut adalah 17,70 1,16 m; 60,32 2,22 m; 49,316 1,93 m; dan 129,11 7,43 m. Hasil histokimia sebaran glikogen pada hati ayam buras hari ke-14, hari ke- 20 sebelum menetas dan hari ke-7 setelah menetas berturut-turut adalah 1,44 0,93; 2,27 0,74; dan 2,77 0,15. Dapat disimpulkan, bahwa diameter vena central dan sebaran glikogen meningkat seiring pertumbuhan ayam buras.(Histological, histomorphometrical, and histochemical of liver on native chicken (Gallus gallus domesticus) during pre and posthatch period) ABSTRACT. The liver is the largest gland in the body and considered as a central organ in maintaining energy supplies. The study aimed to determine the histologic, histomorphometric and histochemical of glycogen distribution in the liver of native chicken during pre and posthatching period.. The study sample were divided into four different age groups and each group consisted of six chicken livers. The results showed a significant difference (P0,05) in native chicken liver growth macroscopically. In every development there are already polygonal hepatocytes that have a round cell nucleus in the middle of the hepatocytes, there is also a central vein that is coated with a layer of flat endothelial cells and also sinusoids that are between the hepatocytes, and kupffer's cells also found in chicken liver 7th day posthatching. The results measurements of the central vein diameter in liver native chickens on the 7th, 14th, 20th pre hatching period and 7th post hatching were 17.70 1.16 m; 60.32 2.22 m; 49.32 1.93 m; and 129.11 7,43 m; The measure results of the glycogen distribution in liver native chickens on the 14th, 20th pre hatching period and 7th post hatching were 1,44 0,93; 2,27 0,74; and 2,77 0,15. It can be concluded, that central vein diameter and glycogen distribution were increased by growth of native chickens.

Abstract

ABSTRAK. Penelitian ini bertujuan untuk mengevaluasi performa tiga strain ayam broiler yang umumnya dipelihara di Aceh. Materi yang digunakan adalah 150 ekor anak ayam broiler (DOC) strain Cobb 500, CP 707, dan MB 202 masing-masing berjumlah 50 ekor. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) yang terdiri dari 3 perlakuan dan 5 ulangan. Setiap ulangan merupakan unit percobaan yang masing-masing terdiri dari 10 ekor anak ayam. Perlakuan adalah tiga strain ayam broiler: Cobb 500 (P1), CP 707 (P2), dan MB 202 (P3). Parameter yang diamati meliputi pertambahan berat badan, konsumsi ransum, konversi ransum (FCR), mortalitas, dan Income over Feed and Chick Cost (IOFCC). Hasil penelitian memperlihatkan performa broiler dipengaruhi oleh jenis strain. Strain MB 202 dan CP 707 memiliki bobot badan akhir (6 minggu) dan konsumsi ransum nyata (P0,05) lebih tinggi daripada Cobb 500. Angka konversi ransum tidak memperlihatkan perbedaan yang nyata antara ketiga strain pada semua umur panen. Nilai IOFCC tertinggi dipengaruhi oleh jenis strain dan lama pemeliharaan. Dari hasil penelitian dapat disimpulkan bahwa performa broiler dipengaruhi oleh kemampuan adaptasi strain terhadap iklim setempat (pesisir Aceh) pada periode berbeda-beda yang dapat memengaruhi tingkat keuntungannya. Strain Cobb 500 memiliki kemampuan adaptasi lebih baik selama periode awal, sedangkan CP 707 dan MB 202 selama periode akhir.(Evaluation of performances and income over feed chick cost (iofcc) of three broiler chicken strains commonly marketed in Aceh) ABSTRACT. The study aimed to evaluate the performances and Income over Feed and Chick Cost (IOFCC) of three broiler chicken strains commonly marketed in Aceh. As many as 150 chicks of three different broiler strains (50 birds each) were used in this study. The study was performed into Completely Randomized Design (CRD) consists of 3 treatments and 5 replications creating 15 experimental units containing 10 birds each. The treatments were 3 different strains of broiler chickens i.e. Cobb 500, CP 707, and MB 202. The birds were reared up to 6 weeks to expose their performances recorded as final body weight, body weight gain, feed intake, and feed conversion, as well as mortality. Economic value was evaluated by calculating IOFCC. Results of study showed that performances of broilers were significantly (P0,05) influenced by the strains. Strains MB 202 and CP 707 represented more superior than Cobb 500 for 56 weeks of raising periods. However, the later was not inferior during initial phase close to 4 weeks. There were no significant differences in FCR among all strains for different ages. The IOFCC related to the strains and their marketing ages. The highest IOFCC was obtained by Cobb 500, CP 707, and MB 202 as they were sold at the ages of 4, 5, and 6 weeks, respectively. In conclusion, the achievements of the performances in various broiler strains were affected by the site climate (Aceh) in different stages of their ages. Cobb 500 had proper adaptation during starter, while CP 707 and MB 202 appeared seem to be better than Cobb 500 during finisher period.
