Reproductive Profile of Etawah Crossbred Does Fed Flushing Diet Containing Different Kinds of Plant Oil and Animal Fat.

BACKGROUND AND OBJECTIVE: Reproduction system is affected by nutrient status of the animal. Flushing is one of reproduction program where the animal should give good quality diet. This study was aimed to evaluate etawah crossbred does reproduction performance giving flushing diet with different fat sources. The fat of plant oils are sunflower and flaxseed and from animal oils are tallow and Lemuru fish. MATERIALS AND METHODS: Twenty four of Etawah crossbred does (average body weight 33.83±3.70 kg) were used in this experiment by using completely randomized block design. There are four treatments with four animals of each treatment. The treatments were flushing diet containing 5% sunflower oil (R1), 5.2% flaxseed oil (R2), 5.3% tallow (R3) and 5% Lemuru fish oil (R4). Treatment was given three weeks before and two weeks after matting, following 2 weeks before partus. During pregnant, the does were given basal diet (ratio concentrate:napier grass was 70:30). Body condition score, nutrient status, blood metabolite and hormone and also performance reproduction were evaluated. RESULTS: The nutrient consumption was same in all treatment. Blood glucose were same in all treatments but the highest blood cholesterol was in R3 during estrus and in R4 during mid gestation. The highest plasma estradiol was in R1 during early gestation, while the highest plasma progesterone was in R2 during late gestation. Litter size and birth weight were same in all treatment, while the highest total embryo was in R2 treatment. CONCLUSION: It is concluded that flaxseed oil for flushing diet was significantly increased number of total embryo.

The Need for a New Cut-off Value to Increase Diagnostic Performance of Bioelectrical Impedance Analysis Compared with Dual-Energy X-ray Absorptiometry to Measure Muscle Mass in Indonesian Elderly.

BACKGROUND: the use of bioelectrical impedance analysis (BIA) is affected by the population setting, the type of BIA, and the cut-off point being used. The aim of this study was to determine the diagnostic performance of BIA to measure muscle mass in Indonesian elderly outpatients aged 60 years or more. METHODS: a cross-sectional study was conducted at the Geriatric Clinic of Cipto Mangunkusumo Hospital from April to June 2018. The muscle mass was measured using BIA Tanita MC-780MA (Tokyo, Japan) with dual-energy x-ray absorptiometry (DXA) as the reference test. Analysis on the cut-off point was performed based on the Asian Working Group of Sarcopenia (AWGS) criteria and the new cut-off point. RESULTS: from 120 subjects, 74 were female (61.7%). The diagnostic performance of BIA based on AWGS criteria only showed sensitivity and specificity of 79.2% and 66.7%. The diagnostic performance of BIA based on the new cut-off point showed sensitivity and specificity of 75% and 92.7%. The new cut-off point using BIA was found to be <6.9 kg/m2 in males (sensitivity 70.6%; specificity 82.8%) and <5 kg/m2 in females (sensitivity 85.7%; specificity 97%). CONCLUSION: the diagnostic performance of BIA Tanita MC-780MA (Tokyo, Japan) was good to measure muscle mass in Indonesian elderly outpatients using a new cut-off point of <6.9 kg/m2 for males and <5 kg/m2 for females.
