Effect of Diet Containing Gracilaria Sp. Waste and Multi-Enzyme Additives on Blood Lipid Profile of Local Duck

Abstract

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.

Blood Mineral Response of Local Duck Fed the Diet Containing Seaweed Gracilaria sp. Waste and Additives Multienzyme

“…Environmental causes acid lipase activity to be limited, so that the reduced fat digestion and subsequent formation of body lipid would be decreased. Decrease in blood lipid has been investigated by Frasiska (2016) showed significantly decreased results after the provision of rations containing seaweed wastes and multienzyme.…”

Seaweeds, Intact and Processed, as a Valuable Component of Poultry Feeds

“…Seaweeds contain polysaccharides (brown algae: alginate, cellulose, fucoidan, laminarin; red: agar, carrageenan, cellulose, porphyran, xylan; green: cellulose, inulin, pectin, xylan, ulvan), proteins, essential amino acids, minerals (K, Ca, Mg, Zn, Cu, Co, I, B), vitamins (B12, K, C, E, A, D), lipids, polyunsaturated fatty acids (PUFA), pigments such as carotenoids (carotene xanthophyll), chlorophylls, phycobilins (e.g., phycoerythrin) and many antioxidant compounds, Figure 1. Examples of seaweeds used in poultry feeding [15,18,[20][21][22][30][31][32][33][35][36][37][38][39][40][41].…”

“…The second source of seaweeds used in feeding experiments on poultry is waste generated from the algae cultivation, which still has a valuable chemical composition. Frasiska et al (2016) estimated that about 65-70% of the total seaweed cultivation (Gracilaria sp. in Indonesia) is waste which has no commercial value and can be converted into feed material for poultry [38].…”

“…Frasiska et al (2016) estimated that about 65-70% of the total seaweed cultivation (Gracilaria sp. in Indonesia) is waste which has no commercial value and can be converted into feed material for poultry [38]. Ventura et al (1994) in the feeding experiments on adult cockerels and 3-week-old chicks used green seaweed Ulva rigida, which was cultivated, then washed with fresh water, air-dried (~85% dry matter) and finally ground [41].…”

“…Appropriately selected seaweeds applied at low inclusion levels can improve not only poultry growth performance and the quality of products, but also their health status (e.g., immune function) due to alteration of gut microbiome and antioxidant properties and can be considered an alternative to antibiotic growth promoters (AGP) used in poultry production [21,[28][29][30][31][32][33][34][35][36]. Most often, seaweeds are used as feed additives for hens and broilers, but there are also a few reports on their application in duck [30,37,38], Japanese quail [39,40] and cockerel [41] feeding.…”
