Produksi dan kualitas Susu Kambing Perah Anglo Nubian Satu Masa Laktasi (Studi Kasus di Balitnak Ciawi Bogor)
No full textKambing perah merupakan bangsa ternak yang menghasilkan daging dan susu. Kambing anglo nubian merupakan kambing hasil silangan dari kambing perah Jamnapari dan kambing Zaraibi, lalu disilangkan dengan bangsa ternak lokal yang ada di Inggris dan dikembangkan. Tujuan penelitian ini adalah untuk mengamati produksi dan kualitas susu kambing perah anglo nubian pada 1 masa laktasi. Sebanyak 22 kambing perah betina anglo nubian yang berasal dari Balai Penelitian Ternak Ciawi. Kambing berada pada bulan laktasi yang berbeda dengan bobot dan masa laktasi yang berbeda. Ternak anglo nubian diberikan pakan hijauan sebesar 4% dari bobot badan dengan perbandingan hijauan dan konsentrat 60:40. Pencatatan suhu kandang, produksi susu, pemberian pakan, dan sisa pakan dilakukan setiap hari. Pengujian susu selama 3 kali pada awal, tengah, dan akhir pengamatan. Pengamatan dilakukan selama 8 minggu. Data hasil penelitian dianalisis secara deskriptif. Hasil yang didapat yaitu rataan konsumsi pakan konsumsi BK 1 824 g ekor-1 hari-1, pakan protein sebesar 218 g ekor-1 hari-1, lemak 203 g ekor-1 hari-1, energy 48.964 Kcal kg-1, serat kasar 237 g ekor-1 hari-1dan abu 134 g ekor-1 hari-1. Rataan persentase konsumsi BK yaitu 4.13%. Bobot rataan ternak 47.20 kg dengan PBBH 0.71 g. Produksi susu dengan rataan sebesar 0.400±0.166 kg. Kualitas susu kambing anglo nubian dengan rataan berat jenis 1.025, lemak 5.671%, protein 4.06%, laktosa 4.12%, SNF 8.4% dan titik beku -0.841. Produksi susu anglo nubian masih rendah dengan kualitas susu tergolong baik
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Produksi dan kualitas susu kambing persilangan Anglo Nubian dan kambing PE
No full textSusu kambing perah memiliki keunggulan dibandingkan susu sapi, karena
mudah dicerna dan tidak menimbulkan gangguan pencernaan dan alergi. Mutu
kambing perlu ditingatkan untuk memenuhi kebutuhan masyarakat. Salah satu
pengembangan kambing perah yang dilakukan di Balai Penelitian Ternak yaitu
menyilangkan kambing anglo nubian (AN) dengan kambing peranakan etawah
(PE). Tujuan dari penelitian ini adalah untuk mengidentifikasi produksi susu
kambing persilangan anglo nubian (AN) dengan peranakan etawah (PE) yang
memproduksi susu dan menguji kualitas susu selama masa laktasi. Penelitian
dilakukan di Balai Penelitian Ternak Ciawi Bogor dari bulan Maret sampai April.
Kambing yang digunakan dalam penelitian ini yaitu kambing betina laktasi
sebanyak 20 ekor pada laktasi bulan 1-8 selama 1 bulan dengan periode laktasi
berbeda. Pengukuran produksi susu dilakukan berdasarkan catatan pemerahan
harian dan kualitas susu diperoleh dengan uji susu menggunakan Lacto-scan. Data
yang dikumpulkan dianalisis menggunakan metode analisis deskriptif. Produksi
susu kambing berada pada puncak laktasi pada bulan pertama dan mengalami
penurunan pada bulan berikutnya. Kualitas susu kambing persilangan AN dan PE
di Balitnak Ciawi dapat dikatakan baik karena memiliki komponen susu lebih
baik dari SNI, yaitu dengan rataan protein 4.2% dan rataan kandungan lemak
sebesar 5.6%
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
Factors Affecting Twinning and the Impacts of Twinning in Cattle
Full text linkEfforts to increase cattle production can be done through increasing the population and productivity of cattle, one of which is through the birth of two offsprings per parent (twin). The incidence of twinning in cattle ranged 1-10%, and influenced by genetic/breed, parity, management, season of breeding. This paper presented factors and technology that increase twinning rate and the impacts of twin births in cattle. There are genetic and non genetic factors affecting twinning rate. Increased twin births can be done through some technologies such as selection, reproduction and management. The problems in twinnings are the high incidence of abortion, early embryonic loss, distochia, retained placenta, metabolic disorders, and ketosis resulting in longer calving interval. Intensive management to dam bearing twins can reduce the problems. Economically, the profits of twinning are different between beef and dairy cattle. Twin births give benefit to beef cattle farming through the increase in total weaning per cattle. The pros and cons of twin births occur in dairy cows farming, especially on milk production
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
