“…Moreover, seaweeds have also shown positive effects on semen quality and fertility traits in ruminants (9,10) and nonruminant animals such as rabbits (11,12) under summer conditions. However, digestibility studies on seaweeds, and particularly Ulva lactuca, as a feed supplement to animals are scarce (3,13). More studies are needed to evaluate seaweed as a feed supplement in the diets of ruminants; therefore, the current study was conducted to evaluate the effects of feeding a diet supplemented with different amounts of seaweed (Ulva lactuca) on the growth performance of Naimey sheep and in vitro gas production, estimated energy, and microbial protein synthesis.…”

This study was carried out to determine the effect of dietary seaweed (Ulva lactuca) supplementation on growth performance of sheep, in vitro gas production, estimated energy, and microbial protein synthesis. A total of 18 Naimey male sheep with average live weight of 22.78 ± 0.24 kg were randomly allocated to 3 groups. Sheep in group 1 were fed a diet containing commercial feed without seaweed as a control diet, sheep in group 2 were fed the control diet with 3% seaweed, and sheep in group 3 were fed the control diet with 5% seaweed. The supplementation of seaweed had no effect (P > 0.05) on the average daily gain, feed intake, and feed conversion efficiency. The extent of gas production at 72 h was similar among the 3 groups (P > 0.05). There were no significant differences (P > 0.05) in the potential degradability, gas production rate, metabolizable energy, net energy, organic matter digestibility, and microbial protein synthesis among the experimental diets. This study concluded that dietary supplementation of seaweed (Ulva lactuca) has no effect on growth of sheep, in vitro gas production, potential degradability, estimated energy, organic matter digestibility, and microbial protein synthesis.

“…Gracilaria sp. waste was given in the form of flour after the waste was washed to remove salt content, sun-dried to obtain 15% moisture (Ventura et al, 1994) then milled into flour. Multi-enzyme additive used was Allzyme SSF from Alltech Ltd. consisted of Non Starch Polysaccharides breaker enzyme or NSP (cellulase, xylanase, pectinase, β-glucanase), amylase, phytase and protease enzyme at a dose of 150 g/ton of feed.…”

Abstract. This study was aimed to evaluate the effect of diet containing waste of seaweed Gracilaria sp. on local lipid profiles of duck blood including cholesterol, triglycerides, low density lipoprotein (LDL), and high density lipoprotein (HDL). The material in this study were 72 female Tegal ducks aged 22 weeks with 1,318 ± 121 g average body weight, diets containing Gracilaria sp. waste (GW) with 18% protein and 2900 kcal/kg metabolic energy and 150 g/ton feed commercial multi-enzyme (ME). Data were subject to Completely Randomized Design with 6 treatments, (T0) Basal Diets, (T0+) Basal Diets with ME, (T1) Diets with 10% GW, (T1+) Diets with 10% GW + ME, (T2+) Diets with 12.5 % GW + ME, and (T3+) Diets with 15% GW + ME. The treatment was given for 12 weeks and blood sample was taken on the last week. The serum was separated and analyzed for blood lipid profiles using CHOD-PAP. Results showed that diet with 12.5%GW plus multi-enzyme additives significantly (P<0.05) affected blood lipid profiles of local duck, tended to lower triglycerides and LDL Cholesterol, but increase blood HDL levels.Key words: blood lipids, local ducks, Gracilaria sp. waste, multi-enzyme Abstrak. Penelitian ini bertujuan untuk mengevaluasi pengaruh ransum yang mengandung limbah rumput laut Gracilaria sp. Terhadap profi lemak darah itik local antara lain kolesterol, trigliserida, low density lipoprotein (LDL), dan high density lipoprotein (HDL).Materi yang digunakan dalam penelitian ini adalah itik Tegal betina umur 22 minggu dengan bobot badan rata-rata 1.318±121g sebanyak 72ekor, ransum mengandung limbah Gracilaria sp. (LG) dengan protein 18% dan energy metabolis 2900 kcal/kg dan multienzim (ME) komersial dengan dosis penggunaan 150 g/ton pakan. Penelitian menggunakan Rancangan Acak Lengkap dengan 6 perlakuan yaitu (T0) Ransum Basal, (T0+) Ransum Basal dengan ME, (T1) Ransumdengan 10% LG (T1+) Ransumdengan 10% LG + ME, (T2+) Ransum dengan 12,5% LG + ME (T3+) Ransum dengan 15% LG + ME. Perlakuan dilakukan selama 12 minggu dan pengambilan sampel darah pada minggu terakhir. Serum dipisahkan dan dianalisis profile mak darah menggunakan metode CHOD-PAP. Hasil menunjukkan bahwa pemberian ransum mengandung LG 12,5% ditambah aditif multienzim berpengaruh nyata (P<0,05) terhadap profil lemak darah itik lokal, cenderung menurunkan Trigliserida, Kolesterol LDL sebaliknya meningkatkan kadar HDL darah.

“…Tetapi penggunaan rumput laut dalam ransum unggas berpengaruh terhadap penurunan performa ternak, sebagaimana penelitian yang dilakukan oleh Ventura et al (1994), bahwa penggunaan rumput laut Ulva rigida 20% dan 30% menurunkan AME (Apperent Metabolism Energy), pertambahan bobot badan, dan peningkatan konversi pakan; Zahid et al (1995), penambahan 20% dan 30% rumput laut menyebabkan penurunan bobot tubuh, hal ini disebabkan oleh garam yang terkandung dalam rumput laut yang menyebabkan ternak terserang diare; Zaid et al (2001), pemberian 20%, 30%, dan 40% menunjukkan penurunan petumbuhan pada ternak; Al-Harthi dan El-Deek (2011), penggunaan 6% rumput Tabel 1.

“…Pada beberapa penelitian, rumput laut yang digunakan dalam penelitian dicuci dengan air tawar terlebih dahulu untuk menanggalkan sisa-sisa pasir, karang-karang kecil dan garam yang menempel pada rumput laut tersebut (Zahid et al, 1993;Ventura et al, 1994;Ginzberg et al, 2000;Zahid et al, 2011;Wisnu dan Rachmawati, 2005;Kumar dan Kaladharan, 2007;El-Deek dan Brikaa, 2009a;El-Deek dan Brikaa, 2009b;Ozaki et al, 2013). Selain itu, ada suatu penelitian oleh Naidu et al (1993), rumput laut yang digunakan dalam penelitian dibersikan dengan air laut untuk tujuan yang sama.…”

ABSTRAKTulisan ini dibuat untuk mengetahui potensi, faktor pembatas, dan pengolahan rumput laut coklat (Phaeophyceae) sebagai pakan ayam petelur. Rumput laut coklat (Phaeophyceae) adalah rumput laut yang mengandung pigmen klorofil a, karotin, xanthofil dan fukosantin, pigmen yang dominan adalah fukosantin yang menutupi warna lainnya dan menyebabkan rumput laut ini kelihatan berwarna coklat. Rumput laut coklat memiliki potensi sebagai bahan pakan ayam petelur karena ketersediaan yang melimpah, tidak bersaing dengan kebutuhan manusia, mengandung zat-zat nutrisi, tidak bersifat toksik, kaya asam lemak omega 3, mengandung pigmen fukosantin, alginat dan fukoidan. Faktor pembatas penggunaan rumput laut ini, yaitu 1) Kandungan nutrisi dan kualitas: alginat tinggi, protein rendah, dan energi rendah; 2) Kandungan anti nutrisi: kadar garam tinggi dan phlorotannin; 3) Penanganan dan pengolahan: membutuhkan berbagai pengolahan khusus sebelum digunakan sebagai pakan ternak. Faktor-faktor pembatas tersebut dapat diatasi dengan perlakuan fisik (pencucian, pengeringan, autoklaf, perebusan dan freezing), fermentasi dan penambahan enzim dalam pakan sebagai upaya untuk meningkatkan ketersediaan zat nutrisi dan mendetoksifikasi senyawa antinutrisi. Rumput laut coklat (Phaeophyceae) memiliki potensi sebagai bahan pakan penyusun ransum ayam petelur.
