The present study was conducted to evaluate effect of Sauropus androgynus extract (SAE) on egg production and lipid metabolism in layer chickens. Forty-eight layers aged 42 weeks (strain RIR) were distributed to 6 treatment groups as follows. One group was fed diet without SAE as the control (P 0 ), and other five groups were fed diet plus hot water-extracted SAE at level of 9 g/kg diet (W 9 ), diet plus ethanol extracted SAE at level of 0.9 g/kg diet (E 0.9 ), diet plus ethanol extracted SAE at level of 1.8 g/kg (E 1.8 ), diet plus methanol extracted SAE at level of 0.9 g/kg (M 0.9 ), and diet plus methanol extracted SAE at level of 1.8 g/kg (M 1.8 ). It was shown that SAE inclusion significantly increased egg production (p<0.05). Methanol-extracted SAE groups had lower egg production than ethanol-extracted SAE group (p<0.05). SAE supplemented groups had better feed conversion efficiency than the unsupplemented group (p<0.05). It was shown that ethanol extracted SAE resulted in the lowest feed conversion efficiency among the SAE supplemented groups (p<0.05). SAE supplementation significantly reduced abdominal fat, gizzard surrounded fat, liver fat (p<0.05), serum triglyceride, total cholesterol, VLDL+LDL-c (p<0.01), atherogenic index (p<0.05), egg cholesterol and triglyceride (p<0.05), but it had no effect on mesenteric fat, sartorial fat and fatty liver score. In conclusion, SAE supplementation could increase egg production but reduced egg cholesterol.
Abstract. Putranto HD, Setianto J, Santoso U, Warnoto, Nurmeliasari, Zueni A. 2012. Estradiol-17β hormone concentration and follicles number in exotic Burgo chicken supplemented by Sauropus androgynus leaves extract. Biodiversitas 13: 1-6. Bengkulu Province of Indonesia has an indigenous crossbreed chicken named burgo or Rejang chicken. A conservation effort in this study was represented by supplementing 4 different levels of Sauropus androgynus or katuk leaves extract (KLE) to improve number of fertile eggs. The purpose of study was to identify the effects of KLE supplementation on female burgo chicken's serum estradiol-17β (E2) hormone concentration profile and number of follicles. KLE was added into drinking water (0, 9, 18 and 27 g/chicken/day) during 8 weeks of treatment. The results showed that supplementation of KLE dosed 9 to 27 g/chickens/day had significantly affected E2 concentrations and number of follicles (P < 0.05). In contrast, the average of female burgo E2 concentration with supplemented KLE was higher than control group. The total number of small follicle yield was highest (86.5%) compared to medium follicle (7.8%) and large follicle (5.3%). Many primary follicles (primordial) and post ovulatory follicles were probably in micro size and unseen by an usual visual counting. It seems that serum E2 hormone concentration correlated to total number of preheararchal follicles. Supplemented KLE was able to improve the serum estrogen steroid hormone concentration and number of preheararchal follicle (small and medium follicles) in female burgo chicken.

Abstract. Praptosuwiryo TNg. 2017. Spore germination and early gametophyte development of Platycerium wandae (Polypodiaceae) from Papua,. Studies on gametophyte development in ferns are very important, as the data generated is often useful for supporting taxa delimitation in ferns and fern-allies. This data is also very important for understanding the ecology, reproductive biology, evolution and distribution of ferns. The study reported here aimed to develop a deeper understand of morphogenesis in the fern Platycerium wandae Racib. by investigating the process of spore germination and early gametophyte development of the species on natural media. Fresh spores of P. wandae were germinated in a mixed media consisting of minced roots of Cyathea contaminans and charcoaled rice hulls (1: 1) under green house condition. Spores of P. wandae are monolete, ellipsoid, nonchlorophyllous, dark brown, and lacking perine. Spores germinated between 7 to 14 days after sowing (DAS). Spore germination of P. wandae is of the Vittaria-type and the prothallial development is of the Aspidium-type, characterized by early development of unicelullar trichomes (30-40 DAS). Only unisexual gametophytes were observed at 60-80 DAS. New data is provided concerning the morphogenesis of P. wandae from Papua, Indonesia, on natural media. The findings are relevant to reproductive biology, would contribute to establish an efficient ex situ propagation strategies for the conservation of epiphyitic ferns and to facilitate further in situ studies of gametophyte ecology.
