摘要：This research aimed to study the supplementation effects of mangosteen pericarp meal (MPM) and vitamin E (VE) in the diets on the egg quality and blood profile of laying hens. This research used 160 laying hens of Lohman strains 24 weeks of age. The observation was conducted for 11 weeks. A completely randomized design with four treatments and four replications (10 birds each) was used in this experiment. The treatments consisted of R0 (control diet), R1 (R0 + 1 g MPM/kg ration), R2 (R0 + 2 g MPM/kg ration) and R3 (R0 + 200 mg VE/kg ration). Variables measured were egg quality, yolk cholesterol, and blood profiles. The data were analyzed by using analysis of variance (ANOVA) and any significant difference between the treatment means were further tested by Duncan’s Multiple Range Test. The results showed that supplementation of 1 g MPM/kg ration in the diet significantly (P<0.05) decreased blood triglycerides compared with the control, laying hens fed with diet suplemented with of 2 g MPM/kg ration, and laying hens with diet suplemented with 200 mg VE/kg ration. Supplementation of MPM and VE did not affect (P>0.05) egg quality (except shell thickness), blood cholesterol, and HDL, respectively. In conclusion, supplementation of 1 g MPM/kg in the diet of laying hens could decrease blood triglycerides.
其他摘要：Penelitian ini bertujuan untuk mengkaji pengaruh suplementasi tepung kulit manggis (TKM) dan vitamin E (VE) di dalam ransum pada kualitas telur dan profil darah ayam petelur. Penelitian ini menggunakan 160 ekor ayam petelur strain Lohman umur 24 minggu yang dipelihara selama 11 minggu. Rancangan yang digunakan adalah rancangan acak lengkap dengan 4 perlakuan dan 4 ulangan (10 ekor setiap ulangan). Perlakuan terdiri atas R0 (pakan kontrol), R1 (R0 + 1 g TKM/kg as fed), R2 (R0 + 2 g TKM/ kg as fed), dan R3 (R0 + 200 mg VE/ kg as fed). Peubah yang diukur adalah kualitas fisik telur, kolesterol telur, dan profil darah. Data yang diperoleh dianalisa secara statistik menggunakan analysis of variance (ANOVA) dan jika terdapat perbedaan nyata antar perlakuan maka dilakukan uji lanjut Duncan’s Multiple Range Test. Hasil penelitian menunjukkan bahwa suplementasi 1 g TKM/kg as fed di dalam ransum menurunkan (P<0,05) trigliserida darah jika dibandingkan dengan kelompok kontrol, ayam petelur yang diberi makan ransum yang disuplementasi 2 g TKM/kg as fed, dan 200 mg VE/kg as fed. Perlakuan suplementasi TKM dan VE tidak mempengaruhi (P>0,05) kualitas telur (kecuali tebal kerabang), kolesterol darah, dan HDL. Kesimpulannya, suplementasi 1 g TKM/kg as fed dalam ransum ayam petelur dapat menurunkan kadar trigliserida darah.
