The present study investigated the supplementation effects of ground cassava (GC) and cassava leaves (CL) with different ratios on digestibility of rice straw (RS) based-diet using in vitro technique. Two stages of in vitro ruminal digestibility were prepared and applied with different dietary treatments following: CON, consisted of 20% RS and 80% GC; T1, consisted of 20% RS, 70% GC, and 10% CL; T2, consisted of 20% RS, 60% GC, and 20% CL; T3, consisted of 20% RS, 50% GC and 30% CL; and T5, consisted of 20% RS, 40% GC, and 40% CL. Each dietary treatment was prepared in quadruplicate. All dietary treatments were incubated into rumen buffer along with three blanks for analysis of ruminal digestibility (in vitro first stage), and then continued into chloride acid solution with pepsin incubation for analysis of total digestibility (in vitro first and second stages). Previously, the rumen fluid was collected from two Bali steers that fed Pennisetum purpureum and commercial concentrate at 8:2 ratio. Both stages were conducted at 39C for 48 h, respectively. In the ruminal digestibility, an increasing ratio of CL was reported to decrease (P<0.05) dry matter digestibility (DMD) and organic matter digestibility (OMD) of diet. Digestibility of crude protein (CPD) in the rumen was highest (P<0.05) in dietary T3, followed by dietary T2, dietary T1, and then dietary T3 and T4, consecutively. Supported with results of ruminal digestibility, an increasing ratio of CL also decreased (P<0.05) DMD and OMD of diet in the total digestibility. Moreover, it also decreased (P<0.05) CPD of diet in the total digestibility. Therefore, the present study concluded that dietary treatment consisting of 70% GC and 10% CL with 20% RS presented the most optimum ratio resulting the highest digestibility through in vitro technique.
采用体外试验技术,研究了不同比例添加木薯粉(GC)和木薯叶(CL)对水稻秸秆基础饲粮消化率的影响。制备两个阶段的体外瘤胃消化率,并采用不同的饲粮处理:CON,由20% RS和80% GC组成;T1为20% RS、70% GC和10% CL;T2为20% RS、60% GC和20% CL;T3: 20% RS, 50% GC, 30% CL;T5为20% RS、40% GC和40% CL。每种饲粮处理配制四份。将所有日粮处理分别放入瘤胃缓冲液和3个空白液中孵育,进行瘤胃消化率分析(体外第一阶段),然后再放入胃蛋白酶氯酸溶液中孵育,进行总消化率分析(体外第一阶段和第二阶段)。在此之前,收集了2头以8:2的比例饲喂紫荆狼尾草和商业精料的巴厘阉牛的瘤胃液。两个阶段分别在39℃下进行48小时。在瘤胃消化率方面,CL比例的增加降低了饲粮干物质消化率(DMD)和有机物消化率(OMD) (P<0.05)。饲粮T3组瘤胃粗蛋白质消化率最高(P<0.05),其次是T2组、T1组、T3组和T4组。与瘤胃消化率结果一致,CL比例的增加也降低了饲粮总消化率中的DMD和OMD (P<0.05)。同时降低了饲粮总消化率的CPD (P<0.05)。因此,本研究通过体外消化技术得出,70% GC + 10% CL + 20% RS的饲粮处理为最佳配比,消化率最高。

The purpose of this study is to analyze the meaning contained in the morphology of the tortoise carapace and plastron using an Islamic approach in the Covid pandemic situation and the simultaneous economic and social crisis. The objects in this study include tortoises, the sociological impacts of the economy due to Covid and their relationship with the theory of H and the Al-Qur'an. Meanwhile, the methodology that will be used in this research is reflexivity and similarity in which the method is to investigate the linkages of the factors that have been mentioned. If you look at its origins, the tortoise shell which has this unique shape makes it an interesting animal to study in the field of vertebrate biology. In this study, the authors will focus on tortoise carapace and plastron. The results obtained in this study are if the tortoise carapace which has a scute of 3 and 1.9 can reflect the values contained in the meaning of Islam, this is evidenced in the Hahslm number 472319. In addition, the marginal number itself has a total scute 24 and 1 nuchal, so can get 7 digits in the numbers 2 + 4 + 1 = 7.
本研究的目的是用伊斯兰教的方法分析在新冠疫情和同时发生的经济和社会危机中龟甲和龟甲形态所包含的意义。本研究的对象包括乌龟、新冠疫情对经济的社会学影响及其与H理论和《古兰经》的关系。同时,本研究将使用的方法是反身性和相似性,其中该方法是调查上述因素的联系。如果你看看它的起源,这种独特形状的龟壳使它成为脊椎动物生物学领域中一种有趣的研究动物。在本研究中,作者将重点研究龟甲和龟甲。本研究得出的结果是,如果带有3和1.9鳞片的龟甲能够反映伊斯兰教意义中所包含的价值,这在472319号哈利姆中得到了证明。此外,边际数本身有一个总刻度24和一个颈数,因此可以得到2 + 4 + 1 = 7的7位数字。

The progression of many diseases due to viruses and bacteria makes for an increase in natural alternative medicine. One source of natural medicine is honey and propolis of stingless bees. Efficacy physical and chemical properties of honey are influenced by the type of pollen and the environment, while geological factors influence the composition of propolis. Bee and stingless bee colonies have a behavior called feed preference. This preference is influenced by several aspects, such as food source location and the selected plant species that produce pollen, nectar, and resins. Therefore, this research was conducted to study the diversity of pollen and the composition of propolis bioactive compounds of stingless bees from Kedungpoh Meliponiculture in Gunungkidul, Yogyakarta. Identification of bees was carried out using a Digital Microscope Super eye . Pollen preparation was made using a modified acetolysis method and observed under a light microscope. The competition of bioactive compounds of propolis was investigated by GC-MS, Gas Chromatograph-Mass Spectrometry. The results showed the diversity of pollen of stingless bees ( T. laeviceps) from Kedungpoh Meliponiculture in Gunungkidul, Yogyakarta was from various plants belonging to 27 families consisting of herbs, shrubs, and trees. The dominated pollen family was from Arecaceae, 26,00 % of the total amounts of pollen. GC-MS result showed that the propolis was composed of 42 types o f t h e bioactive compound and grouped into four categories: terpenoid (62,50%), phenolic (29,22%), steroid (7.08%), fatty acid (1,20%). The most dominant bioactive compound was (Z)-3-(pentadec-8-en-1- yl) phenol (C 21 H 34 O) (23.32%) from the phenolic group.
由于病毒和细菌引起的许多疾病的进展使得自然替代药物的增加。天然药物的一个来源是蜂蜜和无刺蜜蜂的蜂胶。蜂蜜的功效理化性质受花粉种类和环境的影响,而蜂胶的组成受地质因素的影响。蜜蜂和无刺蜂群有一种行为叫做饲料偏好。这种偏好受到几个方面的影响,例如食物来源的位置和所选择的产生花粉、花蜜和树脂的植物物种。因此,本研究对日惹Gunungkidul地区Kedungpoh Meliponiculture地区无刺蜂花粉的多样性和蜂胶生物活性物质的组成进行了研究。利用数码显微镜超级眼对蜜蜂进行鉴定。采用改良的乙酰解法制备花粉,并在光镜下观察。采用气相色谱-质谱联用、气相色谱-质谱联用等方法研究蜂胶中生物活性成分的竞争关系。结果表明,来自日惹Gunungkidul地区Kedungpoh meliponiciculture的无刺蜂(T. laeviceps)花粉的多样性来自草本、灌木和乔木27科的多种植物。主要花粉科为槟榔科,占总花粉量的2600%。GC-MS结果表明,该蜂胶由42种生物活性化合物组成,分为萜类(62,50%)、酚类(29,22%)、甾类(7.08%)、脂肪酸(1,20%)4类。酚基中生物活性最高的化合物为(Z)-3-(pentadeco -8-en-1- yl)苯酚(c21 H 34 O)(23.32%)。

Rice bran is a feed material that is commonly given to poultry, but the amount of its use is relatively low because of its high fiber content. Water hyacinth (Eichhornia crassipes) leaf has a chemical composition similar to rice bran and its availability is abundant but its quality as feed material for poultry is also low because of the high content of the fiber. Some studies showed that fermentation could improve the nutrient content of feedstuffs. A study was conducted to evaluate the efficacy of fermentation using two different cultures incubated for 0, 7, 14, and 21 days. The results showed that protein contents did not differ significantly between the two microbial cultures, but the mixture of rice bran and water hyacinth leaves fermented using a culture containing 5 types of microbes resulted in lower fiber content. The duration of incubation significantly affected both the fiber and protein content. It was concluded that the nutrient content of the mixture of rice bran and water hyacinth leaves could be improved by fermentation using a microbial mixture for 14 days.
米糠是一种常用的家禽饲料材料,但由于其纤维含量高,其使用量相对较低。水葫芦(Eichhornia crassipes)叶的化学成分与米糠相似,可用性丰富,但由于纤维含量高,作为家禽饲料的质量也很低。有研究表明,发酵可以提高饲料的营养成分含量。本研究采用两种不同的培养物,分别培养0、7、14和21天,以评价其发酵效果。结果表明,两种微生物培养物的蛋白质含量差异不显著,但5种微生物混合发酵的米糠和水葫芦叶的纤维含量较低。孵育时间对纤维和蛋白质含量均有显著影响。综上所述,水葫芦叶与米糠混合发酵14 d可提高其营养成分含量。
