Kualitas Semen Berdasarkan Umur pada Sapi Jantan Jawa

The objective of this research was to evaluate the effect of age on semen quality in Java bull. This research was conducted from July to August 2011, and continued in June 2012, located at farmer group of Cikoneng Sejahtera, Banjarharjo, Brebes, Central Java. The materials used were 8 heads of Java bulls, those were 2 heads of <2 years old, 3 heads of 2-3 years old, and 3 heads of >3 years old. All of materials were raised at farmer group in the same management. A number of bulls at each age group were assumed as the replication. Statistical design used was One Way Classification with unbalanced data. Data were analyzed using ANOVA, then followed by Duncan test if there is effect of the bull age. The results showed that age affects semen volume, but did not affect other parameters such as color, pH, consistency, concentration, motility, mortality and normality

Korelasi Antara Bobot Badan Induk Dengan Litter Size, Bobot Lahir Dan Mortalitas Anak Kelinci New Zealand White

This study aims to determine the relationship between body weight of does with litter size, birth weight and mortality in New Zealand White (NZW) rabbits. The research was conducted at the Central Breeding and Raising Non Ruminant Livestock unit Balekambang, Surakarta, Central Java. The material used in this study was 35 does that had sexual maturity and have given birth at least once aged maximum 3 years old. In addition, the study also used 7 bucks aged approximately 2 years. Data were analysed using simple linear regression analysis. The study found that the weight of the does had a very weak correlation value to litter size, birth weight and mortality of young rabbits

Estimation Of Net Primary Production (Npp) Using Remote Sensing Approach And Plant Physiological Modeling(pendugaan Net Primary Production (Npp) Menggunakan Pendekatan Penginderaan Jauh dan Modeling Fisiologis Tanaman)

Information Net Primary Production (NPP) of tropical forests is important for the development of realistic global carbon budgets and for projecting how these ecosystems will be affected by climate changes. This research utilized remotely sensed data and micrometeorological measurement to provide information on vegetation condition. The objective of this research is to estimate spatial NPP using remote sensing approach and plant physiological/micrometeorological modeling. The estimation of NPP is conducted using modeling approach, which is based on relationship between radiation use efficiency, photosyntetically active radiation and fraction of absorbed photosynthetically active radiation by the plants's canopy. Trend of NDVI derived using micrometeorological measurement showed an increase from 2001 to 2002, and then decrease from 2002 to 2004. Average different values (delta) between both methods used to derive NDVI is relatively constant around 0.33 with a high correlation of r2 = 0.98. Using remotely sensed data, the highest NPP values estimated is in year 2003 with value range between 2000 – 2500 (gC m-2 yr-1), less than 2% of the whole forest area. In 2003, 75% area has NPP between 1500 – 2000 (gC m-2 yr-1), meanwhile for 2002 and 2004 it is only 21% and 50 %, respectively. NPP values estimated using micrometeorological measurement show the increasing of NPP values from 2002 to 2003, and then decrease from 2003 to 2004. There is strong correlation between NPP values derived from the two methods with r2 = 0.98

Junior doctors' experiences of managing patients with medically unexplained symptoms: a qualitative study

OBJECTIVES: To explore junior doctors' knowledge about and experiences of managing patients with medically unexplained symptoms (MUS) and to seek their recommendations for improved future training on this important topic about which they currently receive little education. DESIGN: Qualitative study using in-depth interviews analysed using the framework method. SETTING: Participants were recruited from three North Thames London hospitals within the UK. PARTICIPANTS: Twenty-two junior doctors undertaking the UK foundation two-year training programme (FY1/FY2). RESULTS: The junior doctors interviewed identified a significant gap in their training on the topic of MUS, particularly in relation to their awareness of the topic, the appropriate level of investigations, possible psychological comorbidities, the formulation of suitable explanations for patients' symptoms and longer term management strategies. Many junior doctors expressed feelings of anxiety, frustration and a self-perceived lack of competency in this area, and spoke of over-investigating patients or avoiding patient contact altogether due to the challenging nature of MUS and a difficulty in managing the accompanying uncertainty. They also identified the negative attitudes of some senior clinicians and potential role models towards patients with MUS as a factor contributing to their own attitudes and management choices. Most reported a need for more training during the foundation years, and recommended interactive case-based group discussions with a focus on providing meaningful explanations to patients for their symptoms. CONCLUSIONS: There is an urgent need to improve postgraduate training about the topics of MUS and avoiding over-investigation, as current training does not equip junior doctors with the necessary knowledge and skills to effectively and confidently manage patients in these areas. Training needs to focus on practical skill development to increase clinical knowledge in areas such as delivering suitable explanations, and to incorporate individual management strategies to help junior doctors tolerate the uncertainty associated with MUS

Penampilan Berahi Sapi Jawa Berdasarkan Poel 1, Poel 2, dan Poel 3

The purpose of this study was to determine the performance of Java cattle estrus that includes length of estrous, changes in the vulva, the presence of cervical mucus, and the behavior on different ages Java cattle. The study was conducted on July 18, 2011 until August 11, 2011 in KTT Cikoneng Sejahtera, Sub Banjarharjo, Brebes regency, Central Java. Materials used in this study were 11 cows Java has Poel 1 (1 ½ - 2 years) 4 heads, Poel 2 (over 2-3 years) 3 heads, and Poel 3 (above 3-3 ½ years) 4 heads. The parameters measured were the appearance of the vulva, cervix mucus abundance, behavior, and estrous length. The results showed that vulva performance scores of Java cattle Poel 1, Poel 2, and Poel 3 respectively are 1; 1; 1.5. The cervical mucus of Java cattle Poel 1, Poel 2, and Poel 3 respectively are 1; 1; and 2,5. Behavior score for Poel 1, Poel 2, and Poel 3 respectively are 1, 1; 1.5. Estrous length of Java cattle poel 1, 2, and 3 respectively is 10 hours, 12 hours, and 13.5 hours. The conclusion of this research is a female cow Java Poel 3 shows the appearance of a relatively more obvious passion and longer than females Java cows Poel Poel 1 and 2

Pengaruh Perbedaan Waktu Pelepasan Water Jacket dalam Proses Ekuilibrasi terhadap Kualitas Semen Beku Sapi Jawa pada Tahap Before Freezing dan Post Thawing

This experiment was conducted to investigate effect of different water jacket release time on frozen semen quality with two step methods. The semen was collected from four heads Java cattle, extended with skim-egg yolk extender. The extended semen packed with water jacket then release with different time (treatments) T0 (35 minutes), T1 (10 minutes) and T2 (60 minutes) until all equilibration process was finish. Data analysis preparing with normality and homogenity testing, when the data was normal and homogeneous will be followed by analysis of variance (ANOVA). The result showed average of semen quality before freezing T0; T1 and T2 for pH 6,27; 6,27 and 6,43; motility (%) 40,83; 36,67 and 32,50; live sperm percentage (%) 29,68; 33,97 and 22,20; sperm abnormality (%) 20,82; 13,26 and 14,16 respectively. Average of post thawing T0; T1 and T2 for pH 6,27; 6,27 and 6,27; motility (%) 5; 2,92 and 0,42; live sperm percentage (%) 11,21; 12,90 and 19,24; sperm abnormality (%) 22,11; 19,26 and 22,82 respectively. Statistical analysis showed the different water jacket release time did not significantly different (P>0,05) to quality semen of Java bulls at before freezing or post thawing observation
