White-rumped Shama (Copsychus malabaricus) has become a favorite pet among Indonesian bird keepers lately. A champion bird with beautiful chirps and colours would be valued high. There are very limited scientific information on its species, and this study results will enrich the biological data. The purpose of this study was to trace and record white-rumped shama contour feathers growth including feather types and changes of size during fledgling phase. There were 8 mixed sex chicks (a crossbreed of Medan x North Bengkulu) aged 30 days with similar body weight and size used in this study. Daily individual observation on parameters were conducted from day-1 of nurturing until chick’s individual first moulting day. Observation results showed that contour feathers on white-rumped shama chicks body which easily to observed were retrices and remiges. Then, based on anatomical feather during pledgling phase on chick’s part of forehead, nape, chest, back, wing and tail we recorded 3 types of feathers which were filoplumae, plumulae and plumae. Average of retrices length and width in tail were 69.62 mm and 11.10 mm per chick, and average of remiges primarie length and width in wing were 63.32 mm and 9.74 mm per chick, respectively. Researchers found that as similar as to other species of aves, the size of White-rumped Shama retrices is longer and wider than remiges.

Biodiversitas 21: 865-874. Purpose of this research was to estimate number of White-rumped Shama (Copsychus malabaricus) or locally known as murai batu which are kept by Bengkulu's bird keepers, analyze its population density, population distribution, and the profile of bird keepers. Researcher used field observation method by conducting interviews during June-September 2019. Respondents were determined using purposive sampling method and sampling was continued by snowball sampling method. Bird population data were analyzed by using population density formula and population distribution formula, while profile of bird keepers was analyzed descriptively. In 9 sub-districts of Bengkulu City total of 642 birds that are kept by bird keepers in ex-situ habitat, consisting of 434 males and 208 females with sex ratio approximately of 2:1. Population density was 4.23 birds per km2 (2.86 male birds/km2 and 1.37 female birds/km2). Population distribution by a Variance-Mean Ratio formula was 4.8 or VMR > 1. Furthermore, there were 79 keepers consist of 78 male bird keepers (98.7% ) and 1 female keeper (1.27%). Eleven bird keepers (13.9%) were categorized as captive breeders and 68 keepers (86.1%) were categorized as bird hobbyists. In conclusion, density population of ex-situ White-rumped Shama in Bengkulu City was 4.23 birds per km2, and population distribution interpreted as negative binomial distribution. Bird keepers were divided into two groups, captive breeders and bird hobbyists.

Abstract. Putranto HD, Hasibuan GP, Yumiati Y, Ginting SM. 2017 . Effect of katuk (Sauropus androgynus) powder supplementation on the levels of progesterone (P4) and estradiol-17β (E2) hormones in kacang goat (Capra aegragus). Nusantara Bioscience 9: 86-91.Kacang goat (Capra aegragus) is one of Indonesian endemic ruminant species which commonly retained by the community in Indonesia. This species is classified as a small ruminant which has many benefits i.e easy to be domesticated and to adapt, and has an economical value especially for saving purposes to farmers in marginal areas. This study aimed to observe the effects of the katuk powder supplementation (Sauropus androgynus) in the feed of kacang goats on the level of reproductive hormones (progesterone (P4) and estradiol-17β (E2)) in female kacang goats. A total of 9 female kacang goats which meet the prerequisite samples i.e reaching the age of a sexual maturity, having a homogenous weight (12.00 ± 1.00 kg) and in healthy condition were then devided into three groups of treatments using a Completely Randomized Design method. Each treatments consisted of 3 kacang goats as a replication. The treatments consisted of: (i) feed without katuk powder supplementation (control), (ii) feed with the concentration of katuk powder supplementation was 3% of kacang goat's body weight, and (iii) feed with the concentration of katuk powder supplementation was 6% of kacang goat's body weight. After 60 days of treatments, the results showed that the supplementation of katuk powder on female kacang goats had no significant effect on the level of progesterone and estradiol-17β in the first sampling (day-0, P>0.05), however the treatment had a significant effect to the level of progesterone and estradiol-17β on the second sampling (day-28) and the third sampling (day-56) with a significance level of P<0.05. It was concluded that the supplementation of katuk powder could increase the level of progesteron and estradiol-17β hormones in kacang goats. The katuk powder supplementation about 3% of goat weight has sufficiently increased the level of reproduction hormones in female kacang goats.

ABSTRAKKambing kacang dikenal sebagai kambing lokal dan merupakan salah satu plasma nutfah ternak ruminansia Indonesia. Kambing lokal ini lazim dipelihara oleh peternak dan menjadi salah satu pensuplai kebutuhan protein hewani masyarakat. Penelitian ini bertujuan untuk melihat pengaruh dari suplementasi tepung katuk (Sauropus androgynus) dengan level pemberian yang berbeda terhadap profil komponen leukosit dan deferensiasinya pada kambing kacang betina fase prasapih. Rancangan percobaan yang dipergunakan adalah Bujur Sangkar Latin (Latin Square). Sebanyak 9 ekor kambing kacang betina prasapih (umur 4 sampai 6 bulan, berat rerata 8,45 ± 1,00 kg) selama 7 minggu dipelihara dalam kandang individu dan mendapat perlakuan 3 aras suplementasi tepung katuk (A: pakan hijauan dan konsentrat ad libitum (HK) + non suplementasi, B: HK + suplementasi 3% dari berat hidup, dan C: HK + suplementasi 6% dari berat hidup) masing dengan 3 ulangan. Hasil analisis ragam menunjukkan bahwa bahwa perlakuan suplementasi tepung katuk berpengaruh tidak nyata terhadap profil komponen leukosit dan deferensiasinya yaitu limfosit, monosit, netrofil dan eosinofil (P > 0,05). Kondisi (umur, berat badan, seks) kambing betina prasapih yang seragam dalam penelitian ini diperkirakan sebagai penyebabnya. Kondisi individu yang seragam berakibat pada kondisi fisiologis tubuh serta kemampuan produksi antibodi yang sama pula.Kata Kunci: Kambing kacang betina prasapih, Leukosit, Suplementasi tepung katuk ABSTRACT Kacang goat has been well known as one of Indonesian local small ruminant species. This goat can be found easily captived by Indonesian farmers and became as one of animal protein resources. The objective of this study was to monitor the effect of supplemented katuk powdered-feed on pre-weaning kacang does on leukocyte component profile (limfosit, monosit, netrofil dan eosinofil). There were 9 preweaning does (4 to 6 month of age, average weight 8,45 ± 1,00 kg) used in this study and they kept in individual cages during 7 weeks of supplementation period. There were 3 level of supplementation treatments and 3 replications (non-supplemented, supplemented 3%, and supplemented 6%). The result showed that supplementation did not affect goat's leukocyte component profile (P > 0.05). We assumed that similarity of goat age, weight and sex in study led to a similarity for goat physiological status and capability for antibody production.
