Judul: Kausa Dan Cara Pengendalian Panaritium
Abstrak: Panaritium adalah peradangan nekrotik disertai proses pernanahan pada jaringan lunak diantara kuku hewan dari hewan berkuku genap. Adapun jenis ternak yang sering menderita adalah sapi, domba, dan babi. Panatirium yang bersifat khronis pada sapi menimbulkan rasa sakit pada sapi waktu sapi berdiri atau berjalan, sehingga hewan penderita cenderung untuk berbaring. Pada domba, sebagai akibat panaritium yang khronis sering trejadi kukunya terlepas sednagkan pada babi dapat berakhir dengan kematian akibat tejadinya spesies.

Judul: Kausa mastitis bakterial dan cara dianogsa laboratorium
Abstrak: Mestitis atau redang kelenjar ambing merupakan salah satu penyakit pada sapi peran yang menimbulkan kerugian cukup tinggi dan termasuk penyakit yang sulit diberantes. Berdasarkan kausanya mastitis dibagi menjadi mastitis infeksius dan non infeksius yang kejadiannya jarang. Mastitis infeksius disebabkan oleh mikroorganisme bakteri, fungi atau virus. Bakteri merupakan kausa mastitis yang utama. Kejadian mastitis bakterial mencapai 95% (Philpot, 1979) dan sisanya adalah mastitis yang disebabkan oleh fungi atau virus. Streptococcus agalactiae, S. dysgalactiae, S. uberis, Staphylococcus aureus dan S. epidermidis adalah bakteri- bakteri penyebab utama mastitis. Bakteri coliform yakni Escherichia coli dan Klebsiella sp. termasuk penyebab mas titis yang sporadis. Meskipun jarang, mastitis yang dise babkan oleh Corynebacterium pyogenes, Bacillus cereus, Mycobacterium tuberculosis, Pasteurella multocida, Pseudo- monas aeruginosa, Serratia marcescens, Sphaerophorus necro phorus dan Mycoplasma sp. (Blood et al, 1981, Seddon dan Abiston, 1965). ...

Judul: Characterization of The Chemical Constituents and Antioxidant Capacity of Green and Oolong Teas (Camellia sinensis) Manufactured in Thailand
Abstrak: Tea in Thailand most manufactured in northern area, especially Chiang Rai, Chiang Mai, Nan, and Mai Hang Son province. The aim of this study was to determine and compare the chemical compositions and antioxidant capacity of 4 important Thai tea products. A total of 13 of green teas of 2 major cultivars, assamicaand cv. oolong no.12 (chin hsuan oolong) and 26 of oolong tea of 2 major varieties, cv. oolong no. 12 and cv. oolong no. 17 (chin shin oolong) were collected from 18 factories in Chiang Rai province in 2011. The total polyphenol content was determined according to International Organization for Standardization (ISO 14502-1). For antioxidant capacity, DPPH radical scavenging activitiy assay and ferric reducing antioxidant power assay were determined. The catechins content and caffeine content were determined using HPLC by ISO method (ISO-14502-2). Results showed that about 95% of the 39 tea samples manufactured in Thailand had moisture content below 7%, 5% of tea samples being above 7%. The total polyphenol content in green tea was found to vary from 11.86 to 21.19%GAE, while in oolong tea was found in a range of10.22 to 17.57%GAE. The caffeine content in green tea samples were in a range of 1.69 to 3.7%, while in oolong tea samples were in a range of 1.61 to 3.26%. The catechin content in green tea samples were in a range of 8.31-14.08%, while in oolong tea samples were in a range of 6.81-12.46%. The antioxidant capacity in green tea samples was 164.01 mmole TE/100 g dry basis, while in oolong tea samples was about 132.73mmole TE/100 g dry basis. This study provided useful information for the tea industry in Thailand and other countries in processing and selecting a good-quality tea.
