The optimum performance of duck farm can be achieved by providing them with good quality rations. Rations with good digestibility will increase the productivity due to large amount intake of nutrients. Chitosan is type of animal fibre which assisted the growth of useful microbes in digestive system. Addition of chitosan in cattle rations will improve the ecologic of duck digestive system to be more conducive. The aimed of the research was to evaluate rations digestibility with the addition of chitosan. The research was used completely randomized design with 4 treatments and 5 repetitions. Each repetition consists of 2 ducks. The treatments are R0 stands for rations without chitosan and R1-R3 with addition of chitosan 0.5%, 2% and 2.5% respectively. Parameter measured were dried matter, organic matter and crude protein digestibility. Data processing was conducted by using SAS Windows 16. Result showed chitosan addition at 0.5% and 2.5% gave dried matter and crude protein digestibility does not higher than control (P>0.05) while chitosan addition at 2% gave result lower than control. Organic matter digestibility displays balanced in value. Abstrak (Indonesian)Optimalitas peforma ternak itik dapat tercapai jika mendapat ransum berkualitas. Ransum berkualitas dengan kecernaan yang baik akan meningkatkan produktivitas ternak. Kitosan adalah jenis serat hewan yang bermanfaat untuk memicu kehidupan mikroba menguntungkan dalam saluran cerna. Jika diberikan dalam ransum akan menyebabkan ekologis saluran pencernaan ternak itik menjadi lebih kondusif. Tujuan penelitian adalah mengkaji kecernaan ransum dengan pemberian kitosan. Penelitian menggunakan Rancangan Acak Lengkap (RAL) dengan 4 perlakuan dan 5 ulangan. Masing-masing ulangan terdiri dari 2 ekor itik sebagai satuan percobaan. Perlakuan adalah R0 = 0% kitosan, R1 = 0,5% kitosan, R2 = 2% kitosan dan R3 = 2,5% kitosan. Peubah yang diukur adalah kecernaan Bahan Kering, Bahan Organik dan Protein kasar. Data diolah menggunakan program SAS Windows 16. Hasil penelitian menunjukkan bahwa pemberian kitosan 0,5% dan 2,5% memberikan rataan kecernaan Bahan Kering dan Protein Kasar tidak lebih tinggi dari kontrol (P>0,05), sedangkan dosis 2% kitosan nyata lebih rendah dari kontrol, Kecernaan Bahan Organik menunjukkan angka berimbang.Kata Kunci: Kitosan, kecernaan bahan kering, bahan organic, protein kasar, ransum Sahara et al.
Kitosan merupakan produk limbah krustacea bersifat biodegradable, tidak beracun dan mampu mengikat kolesterol, sehingga meningkatkan kualitas telur. Tujuan penelitian adalah melihat pengaruh pemberian kitosan dalam ransum terhadap bobot dan kadar kolesterol telur itik. Penelitian menggunakan Rancangan Acak Lengkap (RAL) dengan 4 perlakuan dan 5 ulangan. Masing-masing ulangan terdiri dari 2 ekor itik sebagai satuan percobaan. Perlakuan adalah R0 = 0% kitosan, R1 = 0,5% kitosan, R2 = 2% kitosan dan R3 = 2,5% kitosan. Peubah yang diukur adalah bobot telur total selama penelitian dan kolesterol telur itik. Data diolah menggunakan program SAS Windows 16. Hasil penelitian menunjukkan bahwa pemberian kitosan memberikan rataan persentase bobot telur yang berimbang antar perlakuan (P>0,05) dan kitosan 0,5% nyata menurunkan kadar kolesterol telur itik terendah (P<0,05) yaitu 10,28 (mg/dg).Kata Kunci : Kitosan, Ransum, Bobot, Kolesterol, Telur ABSTRACTChitosan is a waste product of crustaceans that is biodegradable, non-toxic and able to bind cholesterol, thereby increasing the quality of eggs. The aim of the study was to see the effect of chitosan in the ration on the weight and cholesterol level of duck eggs. The study used a completely randomized design (CRD) with 4 treatments and 5 replications. Each replication consisted of 2 ducks as the experimental unit. The treatments were R0 = 0% chitosan, R1 = 0.5% chitosan, R2 = 2% chitosan and R3 = 2.5% chitosan. The measured variables are total egg weight during research and duck egg cholesterol. The data was processed using SAS Windows 16. The results showed that chitosan gave an average percentage of balanced egg weight between treatments (P> 0.05) and chitosan 0.5% significantly lowered the lowest cholesterol level of duck eggs (P <0.05) that is 10.28 (mg / dg).Keywords: Chitosan, Ration, Weight, Cholesterol, Eggs
ABSTRAKKondisi ekologis saluran pencernaan kondusif berpengaruh terhadap kelancaran metabolisme tubuh. Keseimbangan mikroflora hidup pada saluran pencernaan itik sangat membantu kelancaran pencernaan nutrien ransum menjadi zat yang lebih sederhana. Kitosan merupakan jenis serat hewan yang sangat cocok untuk menunjang kehidupan bakteri jenis menguntungkan dalam saluran cerna. Tujuan penelitian adalah melihat perkembangan mikroflora saluran pencernaan dengan pemberian kitosan. Penelitian menggunakan Rancangan Acak Lengkap (RAL) dengan 4 perlakuan dan 5 ulangan. Masing-masing ulangan terdiri dari 2 ekor itik sebagai satuan percobaan. Perlakuan adalah R0 = 0% kitosan, R1 = 0,5% kitosan, R2 = 2% kitosan dan R3 = 2,5% kitosan. Peubah yang diukur adalah jumlah total populasi mikroba, jumlah Salmonela dan jumlah E coli saluran pencernaan itik. Hasil penelitian menunjukkan bahwa pemberian kitosan 0,5% dan 2% memberikan peningkatan rataan jumlah total mikroba (TPC) pada saluran cerna. Kitosan juga menurunkan jumlah E coli saluran cerna serta kandugan Salmonella sp negative(<10 2 ) Kata kunci: Kitosan, mikroflora, saluran cerna, itik Tegal ABSTRACT Conducive ecological conditions of the digestive tract affect the smooth metabolism of the body. The balance of living microflora in the digestive tract of ducks greatly helps the smooth digestion of nutrients into simpler substances. Chitosan is a type of animal fiber that is potential to support the life of beneficial type bacteria in the gastrointestinal tract. The aim of this research is to see the development of microflora of gastrointestinal tract by giving chitosan. The study used Completely Randomized Design (RAL) with 4 treatments and 5 replications. Each replication consists of 2 ducks as experimental units. The treatment was R0 = 0% chitosan, R1 = 0,5% chitosan, R2 = 2% chitosan and R3 = 2.5% chitosan. The measured variables were total microbial population, number of Salmonella and amount of E coli of duck digestive tract. The results showed that giving of chitosan 0,5% and 2% give increase of total amount of microbe (TPC) in gastrointestinal tract. Chitosan also decreases the amount of E coli gastrointestinal tract and Salmonella sp negative (<102) Keywords: chitosan, microflora, gastrointestinal tract, Tegal duck
