“…Dosis 2 g TKM dipilih untuk menguji pengaruh antioksidan yang dimiliki TKM jika diberikan dua kali lipat di dalam pakan. Dosis 200 mg VE/kg pakan merupakan hasil terbaik dari beberapa penelitian (Jiang et al, 1994;Mori et al, 2003;Florou-Paneri et al, 2006 …”

INTISARIPenelitian ini bertujuan untuk mengkaji pengaruh penambahan jangka panjang herbal alami: tepung kulit manggis (TKM) dan non-herbal: vitamin E (VE) di dalam ransum terhadap organ pencernaan, aksesori, reproduksi dan karkas ayam petelur. Ayam yang digunakan adalah 160 ekor ayam petelur strain Lohman (umur 24 minggu) yang dipelihara selama 11 minggu. Rancangan yang digunakan adalah rancangan acak lengkap dengan 4 kelompok perlakuan dan 4 ulangan (setiap ulangan terdiri dari 10 ekor ayam). Perlakuan terdiri dari: R0 (pakan kontrol), R1 (R0 + 1 g TKM/kg pakan) dan R2 (R0 + 2 g TKM/kg pakan), R3 (R0 + 200 mg VE/kg pakan). Variabel yang diamati adalah: organ pencernaan (persentase tembolok, gizzard, usus halus, dan sekum), organ aksesori (persentase jantung, limfa, ginjal, hati dan empedu), organ reproduksi, bobot hidup, dan karkas ayam petelur. Hasil penelitian menunjukkan bahwa semua perlakuan (R0, R1, R2 dan R3) tidak mempengaruhi organ pencernaan (persentase tembolok, gizzard, usus halus, dan sekum), organ aksesori (persentase jantung, limfa, ginjal, hati, dan empedu), organ reproduksi, bobot hidup dan karkas ayam petelur. Dapat disimpulkan bahwa penambahan jangka panjang tepung kulit manggis 1-2 g/kg pakan dan vitamin E 200 mg/kg di dalam pakan tidak memberikan pengaruh terhadap organ pencernaan, organ aksesori, organ reproduksi, bobot hidup dan karkas ayam petelur.(Kata kunci: Ayam petelur, Karkas, Organ pencernaan, Tepung kulit manggis, Vitamin E) (percentage of crop, gizzard, small intestine and ceca), accesory organs (percentage of heart, spleen, kidney, liver and bile) ABSTRACT This research aimed to study long-term addition natural herbal: Mangosteen pericarp meal (MPM) and non-herbal: vitamin E (VE) in the diet on digestive organs, accessory organs, reproductive organs, and carcass of laying hens. A total of 160 laying hens of Lohman strains (24-wk-old) were used, the observation was conducted for 11 weeks. Designs were a completely randomized design with four treatments and four replications (10 birds each). The treatments consisted of R0 (control diet), R1 (R0 + 1 g MPM/kg diet), R2 (R0 + 2 g MPM/kg diet) and R3 (R0 + 200 mg VE/kg diet). The variabel observation was digestive organs

“…However, the egg weight was not affected by retinol and retinol ester supplementation of the diets (Table 3). Vitamin A has been reported to be essential for egg production; egg production has been shown to decrease in laying hens fed diets deficient in vitamin A (11). Some studies have shown that when retinol ester supplementation contains vitamin A at the required level, egg production remains the same in hens (2,20), and that R-acetate supplementation above the required level increases egg production (2,11).…”

“…This effect was associated with the fact that the feed intake did not change but egg production increased in those groups. It has been reported that vitamin A at the required level for laying hens (2,20) or above the required level for laying quails (21) and R-acetate supplementation for laying hens do not change (2,10,11) or adversely affect (20) the FCR.…”

“…In this study, the retinol content of the egg yolk was determined to increase in the groups with R-palmitate and R-acetate supplementation by 66.2% and 32.1%, respectively, in the first month, and 51.4% and 46.2%, respectively, in the second month (Table 6). Some studies also reported an increase in the retinol content in the egg yolk with retinol (26) and R-acetate supplementation of hen diets (10,11,23). Depending on the forms (12) and the levels (23) of vitamin A in the diet, the liver plays an important role as a regulator of this vitamin's metabolism.…”

“…The National Research Council (NRC) (8) recommends including a calculated amount of vitamin A precursors, which should ultimately yield 3300 IU/kg of feed, to meet the basic requirements of poultry. Studies of poultry have evaluated the effects of the use of various levels of retinol (9), retinyl acetate (R-acetate) (2,10,11), and retinyl palmitate (R-palmitate) (12) on laying performance and egg quality. However, no data are available concerning the use of retinyl propionate (R-propionate) in poultry.…”
