This experiment was conducted to determine growth performance and cost benefit of including cooked Ipomoea asarifolia leaf meal (CIALM) in broiler diets. Eight diets were compounded by including Ipomoea asarifolia leaf meal at 0, 2.5, 5 and 7.5% to form T1, T2, T3 and T4 respectively of both starter and finisher diets. One hundred and twenty broiler birds were used in a Complete Randomized Design experiment that lasted for eight weeks. Daily feed intake and weekly weight gain were measured. Average daily feed intake, average daily weight gain, total feed consumed, feed conversion ratio and cost benefit parameters were calculated. In starter phase results showed that there were significant differences (P<0.05) between treatment means in all the parameters except initial weight of the birds. There were significant differences (p<0.05) between treatment means in all the parameters measured during the finisher phase including the cost analysis parameters except that feed cost decreasing with increasing levels of CIALM and net profit decreased from T1 to T4 because of the decrease in total weight gain from T1 to T4. Final weight gain, total weight gain, average daily feed intake, total feed intake, average daily weight gain, feed conversion ratio, feed cost and feed cost per kg weight gain all decreased with increasing levels of CIALM. Results control diet performed better than other treatment diets which suggest that lower levels of inclusion that is less than 2.5% may give positive results.

本试验旨在确定在肉鸡日粮中加入煮熟的细辛叶粉（CIALM）的生长性能和成本效益。将0、2.5、5和7.5%的细辛叶粉加入8种日粮中，分别形成起始日粮和结束日粮的T1、T2、T3和T4。120只肉鸡被用于一项持续八周的完全随机设计实验。测量每日采食量和每周体重增加。计算了平均日采食量、平均日增重、饲料消耗总量、饲料转化率和成本效益参数。在起始阶段，结果显示，除鸟的初始体重外，处理方法在所有参数上都有显著差异（P<0.05）。在精整阶段测量的所有参数（包括成本分析参数）中，处理方法之间存在显著差异（p<0.05），除了饲料成本随着CIALM水平的增加而降低，净利润由于总增重从T1到T4的减少而从T1降低到T4。随着CIALM水平的提高，最终增重、总增重、平均日采食量、总采食量、平均日增重、饲料转化率、饲料成本和每公斤增重饲料成本均呈下降趋势。结果对照饮食比其他治疗饮食表现更好，这表明较低的包容性水平低于2.5%可能会产生积极的结果。

Feed resource availability and quality are two of the major factors limiting dairy production in the Philippines. Utilization of microbial-based feed additives and agricultural by-products such as cassava pulp aided by fermentation technology can help provide the needed resource. This study aimed to determine the effect of activated yeast (Saccharomyces cerevisiae) solution (AYS) and yeast-fermented cassava pulp (YFCP) on milk production and feed cost-efficiency in dairy buffaloes. The study followed RCBD design using 63 dairy buffaloes at the Philippine Carabao Center in Ubay Stock Farm, Bohol. The average daily milk yield (ADMY) of buffaloes supplemented with 0.5L AYS and 1L AYS twice daily were greater than that of control buffaloes by 0.67L and 0.69L, respectively (P = 0.0039).On the other hand, the ADMY of buffaloes fed with YFCP and YFCP+AYS were greater than that of control buffaloes by 0.64 and 0.68L, respectively (P = 0.0320). Supplementation of AYS and feeding YFCP yielded the lowest cost per liter of milk produced at PhP 20.25 and PhP 16.24, respectively. It is recommended to supplement milking dairy buffaloes with AYS or feeding YFCP in areas with cassava pulp to increase feed resource, increase milk production and improve feed cost-efficiency thereby increasing significantly the farmer’s income.

饲料资源的可用性和质量是限制菲律宾乳制品生产的两个主要因素。在发酵技术的帮助下，利用微生物饲料添加剂和木薯浆等农业副产品可以帮助提供所需的资源。本研究旨在确定活性酵母（酿酒酵母）溶液（AYS）和酵母发酵木薯浆（YFCP）对水牛产奶和饲料成本效益的影响。这项研究遵循了RCBD的设计，在波荷尔乌贝畜牧场的菲律宾卡拉包中心使用了63头水牛。每天两次添加0.5L AYS和1L AYS的水牛平均日产奶量分别比对照水牛高0.67L和0.69L（P=0.0039），补充AYS和喂养YFCP产生的每升牛奶成本最低，分别为20.25和16.24 PhP。建议在产奶水牛中添加AYS或在木薯浆地区添加YFCP，以增加饲料资源，增加牛奶产量，提高饲料成本效率，从而显著增加农民收入。

Nutrition and rearing systems are some of the main factors affecting productivity of cows. Body condition score (BCS) is a method used to assess nutritional status and evaluate rearing systems of each animal. This study was done to analyze effect of BCS on reproductive performance and chest girth of Bali cow in different rearing systems. This study was conducted at the Field Station of Sekolah Peternakan Rakyat Kuamang Abadi, Bungo Regency, Jambi, Indonesia. A total of 62 heads of Bali cow with BCS of 2, 3, and 4 (scale 1-5) reared on intensive, semi-intensive and extensive systems were used in this study. This study was conducted using survey and direct observation. Variables observed were as follows: BCS, calving interval (CI), days open (DO), service per conception (S/C) and chest girth (CG). Data were analyzed using simple correlation and regression analysis in SPPS, followed by descriptive analysis. Result showed that the BCS of Bali cow in different rearing systems did not affect CI, DO, S/C and CG. BCS had a weak correlation coefficient (r), with the reproductive performance of CI, DO, and S/C at 0.09, 0.09, and 0.08, respectively. In addition, the relationship between BCS and CG was highly significant, with a correlation coefficient (r) of 0.532. Therefore, BCS had a positive relationship with CI, DO, S/C, and CG. Moreover, BCS cannot be used as the only indicator to assess the reproductive performance of Bali cow in different rearing systems.

Broiler litter waste is increasing as the population of broiler chickens increases, on the other hand the need for ruminant feed is increasing so that alternative feeds are needed in the form of complete feed made from litter. This study was aimed to determine the effect of fermentation time on the nutritional content and digestibility of the complete feed. A completely randomized design with 4 treatments and 5 replications were applied in this study. Treatment T0 = not fermented; T1 = fermentation for 10 days; T2 = fermentation for 24 days; T3 = fermentation for 38 days. Parameters observed were nutrient content, VFA, NH3, dry matter digestibility and organic matter digestibility in vitro using cow rumen. Results showed that fermention of complete feed with 2.5% EM4 starter and 5% probiofeed for 38 days (T3) had a significant effect (P<0.05) on nutrient content, dry matter digestibility, organic matter digestibility, VFA and NH3. The T3 significantly affected ash content, crude fat, crude protein, BETN, TDN, dry matter digestibility, organic matter digestibility, VFA, and NH3 but had no significant effect on water content and crude fiber. It is concluded that the complete feed could be used as an alternative feed for ruminants, and it is easy to obtain, cheap and able to reduce environmental pollution.

随着肉鸡数量的增加，肉鸡窝垃圾也在增加，另一方面，对反刍动物饲料的需求也在增加，因此需要替代饲料，即用肉鸡窝制成的全饲料。本试验旨在研究发酵时间对全饲料营养成分和消化率的影响。本研究采用完全随机设计，4个处理，5个重复。处理T0 =不发酵;T1 =发酵10天;T2 =发酵24天;T3 =发酵38天。通过奶牛瘤胃观察营养物质含量、VFA、NH3、干物质消化率和有机物消化率。结果表明，添加2.5% EM4发酵剂和5%益生菌饲料的完全饲料发酵38 d (T3)对营养物质含量、干物质消化率、有机物消化率、VFA和NH3有显著影响(P<0.05)。T3显著影响了粗灰分、粗脂肪、粗蛋白质、BETN、TDN、干物质消化率、有机物消化率、VFA和NH3，但对水分和粗纤维无显著影响。综上所述，该饲料可作为反刍动物的替代饲料，且易于获取、价格低廉且能减少对环境的污染。

Competitiveness of layer business was determined by the level of efficiency, which was influenced by the level of technology adoption, production costs, and economy of scale. This study was carried out from April to July aim to analyse the performance of small-scale layer poultry farming. The study site was in the layer production centre, namely in Payakumbuh West Sumatera, Blitar East Java and Sidrap South Sulawesi. Primary data were collected through interviews with 50 farmers and 12 poultry shops at all study sites. Analysis of the efficiency level is using DEA (Data Envelopment Analysis) software and business feasibility using financial analysis. The following were the main research findings: (1) the development of layer farming technology had not been responded well by farmers so that the production level and mortality of chickens were still below standard; (2) relatively, the level of layer poultry farming efficiency in Sidrap and Payakumbuh was better than in Blitar with a value closer to one, where the inefficiency was due to the use of excessive inputs; and (3) small-scale layer poultry farming was financially feasible, where the determining factors were feed and eggs price. The study recommended the need to add both technical service staff from poultry shops and local agricultural extension workers. Feed costs should be reduced by IDR 1,000 in Blitar and IDR 57 di Sidrap per kilogram of eggs produced per period. In addition, an accurate and better allocation of corn for feed was needed to optimise the ratio of feed and egg price optimal.

分层企业的竞争力由效率水平决定，而效率水平又受技术采用水平、生产成本和规模经济的影响。本研究于4月至7月进行，旨在分析小规模蛋鸡养殖的生产性能。研究地点位于层生产中心，即西苏门答腊的Payakumbuh，东爪哇的Blitar和南苏拉威西的Sidrap。通过对所有研究地点的50名农民和12家家禽店的访谈收集了主要数据。效率水平分析采用DEA(数据包络分析)软件，业务可行性分析采用财务分析。主要研究结果如下:(1)蛋鸡养殖技术发展反响不佳，鸡的生产水平和死亡率仍低于标准;(2)相对而言，Sidrap和Payakumbuh的蛋鸡养殖效率水平优于Blitar，其低效率水平接近于1，其低效率是由于过度投入造成的;(3)小规模蛋鸡养殖在经济上是可行的，其中决定因素是饲料和鸡蛋价格。该研究建议需要增加家禽店的技术服务人员和当地农业推广人员。每期每生产一公斤蛋，饲料成本应降低1000印尼盾(以布里塔为单位)和57印尼盾(以西德拉为单位)。此外，需要准确、合理地分配玉米作饲料，以优化料蛋价格比。

This study aimed to determine the effect of fortification of duck eggshellnano-calcium and different types of packaging on the quality of chicken sausage. The sausage was made of duck eggshellnano-calcium, chicken fillet, sugar, garlic powder, salt, pepper, tapioca, ice, oil, soy protein isolate, sodium tripolyphosphate, monosodium glutamate, collagen casing, polyethylene, nylon, and retort pouch packaging. Treatment for fortification of duck eggshellnano-calcium was P0 (0%) and P1 (0.3%) of the total dough. Vacuum packaging treatments were K1 (polyethylene), K2 (nylon), and K3 (retort pouch). All chicken sausages were vacuum-packed and stored at -18°C for 0 and 14 days of observation. Parameters tested were water content, pH value, peroxide value, and total plate count. Data collected were analyzed by analysis of variance in a completely randomized design with factorial patterns and if there was a significant difference (P<0.05) then further tested with Duncan's New Multiple Range Test. Sausage fortified with duck eggshell nano-calcium with vacuum retort pouch packaging was the best treatment with the lowest peroxide value at day 14 shelf life. Sausage fortified with nano-calcium duck eggshell with vacuum retort pouch packaging at day 14 shelf life had moisture (51.59%), pH value (6.83), peroxide value (64.64 meq O₂/kg), and total plate count (3.50 X 10³ cfu/g).

Osteoporosis can be prevented by consuming calcium lactate. Calcium that is consumed is generally in a micro-size. Micro-sized calcium is only absorbed by the body by about 50% which can cause deficiency. Eggshells are poultry waste that is rich in calcium and can be used as a cheap source of dietary calcium through nanotechnology. Nanotechnology has been developed to increase calcium absorption. This study aimed to synthesize nano-calcium lactate from chicken eggshells,and commercial calcium oxide by precipitation method. Synthesis was carried out by reacting a solution of 1 mol/L eggshell calcium oxide and commercial calcium oxide (control) as much as 20 ml mixed with a solution of 6 mol/L lactic acids as much as 30 ml with a ratio of 1:1.5 (v/v) for 30 minutes at 50°C at a speed of 500 rpm/minute using a magnetic stirrer. Ethanol 50% was added as much as 20 ml (v/v), oven-dried at 105°C for 72 hours then crushed to produce eggshell nano-calcium lactate (NCaL) powder. Characterisation of NCaL using Transmission electron microscopy (TEM), X-ray diffraction (XRD), and Fourier transform infrared (FTIR). Result showed that NCaL in the form of white crystals could be synthesized from chicken eggshells by precipitation method. Characterization with XRD showed that the diffraction angle was 2θ with the peaks of NCaL, namely 9.3800°, 10.3869°, and 22.9570°. Characterization with FTIR obtained a peak in the wavenumber from NCaL, namely 1,589.34 cm^-1. Characterization using TEM showed that the crystal size of NCaL was 75 nm.

骨质疏松症可以通过摄入乳酸钙来预防。人们摄入的钙通常是微量的。微量钙只能被人体吸收约50%，这可能导致缺钙。蛋壳是富含钙的家禽废物，可以通过纳米技术作为廉价的膳食钙来源。纳米技术被用来增加钙的吸收。以鸡蛋壳和商品氧化钙为原料，采用沉淀法合成纳米乳酸钙。以1 mol/L的蛋壳氧化钙溶液和20 ml的商品氧化钙(对照)与30 ml的6 mol/L乳酸溶液以1:1.5 (v/v)的比例在50℃下磁力搅拌器以500转/分钟的速度反应30分钟，进行合成。加入50%乙醇20 ml (v/v)， 105℃烘干72小时，粉碎制得蛋壳状纳米乳酸钙(NCaL)粉末。利用透射电镜(TEM)、x射线衍射(XRD)和傅里叶变换红外(FTIR)对NCaL进行表征。结果表明，用沉淀法可以从鸡蛋壳中合成白色晶体形式的NCaL。XRD表征表明，其衍射角为2θ， NCaL峰分别为9.3800°、10.3869°和22.9570°。用FTIR表征得到了NCaL波数中的一个峰，即1,589.34 cm-1。TEM表征表明NCaL晶体尺寸为75 nm。

The aim of this study was to determine effect of types and dose levels of foliar fertilizers on morphology and production of Clitoria ternatea. This study was conducted from September to November 2020 at Forage Research Garden for Animal Feed and Pasture, Faculty of Animal Science, Gadjah Mada University, Yogyakarta. Materials used were Clitoria ternatea, liquid organic fertilizer of rabbit and gandasil D fertilizer. This study was designed in a Completely Randomized Design (CRD) with factorial pattern of 2x4. The fertilizer dosages were: 0,1.5,3.0 and 4.5 g/l/plot. The parameters measured were plant height, stem diameter, leaf area, number of branches, fresh and dry matter productions. Data were analyzed by the analysis of variance at 5%, with Duncan's Multiple Range Test (DMRT). Results showed that types of foliar fertilizers did not affect morphological characteristics and production of Clitoria ternatea (P>0.05), but the fertilizer dosages had significant effect (P<0.05) on morphological characteristics except for leaf area and production of Clitoria ternatea. The higher the dose level of foliar fertilizer the greater the plant height, stem diameter and number of branches. Dosage of 4.5 g/l/plot resulted in the highest plant height, stem diameter and number of branches each 160.02, 1.14 cm and 18.96 branches, respectively. Dosage of4.5 g/l/plot gave the highest fresh and dry matter production of 19.22 and 16.75 tons/ha. It is concluded that increasing the dosage level of foliar fertilizer up to 4.5 g/l/plot resulted in an increased quantity measures of several morphological characteristics and production.

本研究的目的是确定叶面肥的类型和剂量水平对Clitoria ternatea形态和产量的影响。这项研究于2020年9月至11月在日惹加加马达大学动物科学学院动物饲料和牧场牧草研究园进行。所用材料为Clitoria ternatea、兔液态有机肥和gandasil D肥料。本研究采用完全随机设计（CRD），析因模式为2x4。施肥量分别为：0,1.5,3.0和4.5g/l。测量的参数包括株高、茎径、叶面积、分枝数、新鲜物质和干物质产量。数据通过5%的方差分析进行分析，采用邓肯多程检验（DMRT）。结果表明，不同类型的叶面肥对Clitoria ternatea的形态特征和产量没有影响（P>0.05），但除叶面积和产量外，不同的施肥量对其形态特征有显著影响（P<0.05）。叶面肥的用量水平越高，植株高度、茎径和分枝数就越大。4.5克/升/块的剂量导致最高的株高、茎径和分枝数，分别为160.02、1.14厘米和18.96个分枝。4.5克/升/块的剂量产生了最高的新鲜和干物质产量，分别为19.22和16.75吨/公顷。结果表明，将叶面肥的用量水平提高到4.5g/l/块，可以增加几种形态特征和产量的数量。

The side effect of fatty acid oxidation during lippoprotein synthesis is the release of oxygen in the tissue called reactive oxygen species (ROS). Metabolic stress in Joper brooders due to an imbalance between ROS and antioxidants causes a decrease in hatching egg production and quality. Therefore, research is needed to improve the reproductive performance of Joper broodstock by combining vitamin E-selenium supplementation and metabolic energy. This study used 200 hatched eggs resulting from a cross between 60 weeks old Sentul males and 35 weeks old ISA BROWN laying hens that had been treated. This study used a Factorial Completely Randomized Design (CRD) (2 x 4). The first factor is the energy level (2700 and 2800 kcal/kg) and the second factor is the dose of vitamin E-selenium supplementation (0, 25, 50, 75 and 100 ppm). Selenium dosage is 1ppm/mg vitamin E. The interaction between vitamin E-selenium supplementation and energy had a very significant effect (P<0.01) in increasing DOC weight. The single factor energy level and vitamin E-selenium supplementation significantly (p<0.05) in reducing embryo mortality and increasing hatchability, while fertility and eggshell quality were not affected by the two treatment factors. The conclusion of this study is the interaction between vitamin E-selenium supplementation and energy levels can increase the weight of Joper's DOC, while the single factor of vitamin E-selenium supplementation and energy levels can reduce embryo mortality and increase hatchability. The best interaction with 100 ppm vitamin E-selenium supplementation and energy 2800 kcal/kg.

唇蛋白合成过程中脂肪酸氧化的副作用是组织中活性氧（ROS）的释放。由于ROS和抗氧化剂之间的不平衡，Joper育种鱼的代谢压力导致孵化卵产量和质量下降。因此，有必要研究通过补充维生素E、硒和代谢能量来提高幼鱼的繁殖性能。这项研究使用了经过处理的60周龄Sentul雄性和35周龄ISA BROWN蛋鸡杂交产生的200个孵化蛋。本研究采用因子完全随机设计（CRD）（2x4）。第一个因素是能量水平（2700和2800 kcal/kg），第二个因素是补充维生素E硒的剂量（0、25、50、75和100 ppm）。硒的剂量为1ppm/mg维生素E。补充维生素E硒与能量的相互作用对增加DOC重量有非常显著的影响（P<0.01）。单因素能量水平和补充维生素E硒在降低胚胎死亡率和提高孵化率方面显著（p<0.05），而生育能力和蛋壳质量不受两个处理因素的影响。本研究的结论是，补充维生素E硒和能量水平之间的相互作用可以增加Joper’s DOC的重量，而补充维生素E和能量水平的单一因素可以降低胚胎死亡率并提高孵化率。补充100ppm维生素E硒和能量2800 kcal/kg的最佳相互作用。
