In our previous research, kemuning leaves (Murraya paniculata L. Jack) was shown to have the capability as an anthelmintic candidate for PE (Ettawa crossbred) lactating dairy goats by reducing 43.67% of the egg per gram (EPG) of Strongylida compared to 0.0005% in orally treated with Oxfendazole as a control. To confirm it, the aim of this in vitro study was to determine the effective dosage of kemuning leaves from two extraction methods (infuse and maceration) to reduce the Trichostrongylidae and to evaluate the bioactive compounds of the leaves. The research was conducted using a randomized complete design with 11 treatments and 5 replications. The treatments consisted of control (0.0005% and 0.005% Oxfendazole), kemuning leaves infuse extract (KIE) and maceration extract (KME) each with level of 1%, 3%, 5%, and 7% (w/v). The results showed that the LT50 gradually decreased (shortening the lethal time) and the mortality of Trichostrongylidae gradually increased associated with the increased concentration of treatment (P<0.01). The infusion of 7% kemuning extract demonstrated the highest efficiency in reducing the larval development, infective larvae, and the adult Trichostrongylidae by 93.16%, 94.39%, and 90%, respectively.  This treatment could be developed as the most prospective herbal anthelmintic drug in controlling the infection by Trichostrongylidae.
在我们之前的研究中,克穆宁叶(Murraya paniculata L. Jack)作为一种候选驱虫药,可以使育奶山羊(Ettawa杂交)的圆线虫每克产蛋量(EPG)降低43.67%,而口服奥芬达唑作为对照,每克产蛋量仅为0.0005%。为了证实这一观点,本实验通过测定两种提取方法(浸提和浸提)对克穆明叶的有效剂量,并对其生物活性成分进行评价。本研究采用随机完全设计,共11个处理,5个重复。对照(0.0005%和0.005%奥芬达唑)、克穆宁叶浸膏(KIE)和浸膏(KME)分别为1%、3%、5%和7% (w/v)。结果表明:随着处理浓度的增加,毛圆虫的LT50逐渐降低(致死时间缩短),死亡率逐渐升高(P<0.01);7%克穆宁浸膏对毛圆虫幼虫发育、感染幼虫和成虫的抑制率分别为93.16%、94.39%和90%,效果最好。该药有望成为控制毛圆虫感染最有前途的中药驱虫药。

Three Iranian horse breeds, Turkoman, Caspian, and Kurdish, are the most important Iranian horse breeds which are well known in all around of the world because of their beauty, versatility, great stamina, and  intelligence. Phenotypic characterization was used to identify and document the diversity within and between distinct breeds, based on their observable attributes. Phenotypic characterization and body biometric in 23 traits were measured in 191 purebred horses belonging to three breeds, i.e. Turkoman (70 horses), Kurdish (77 horses), and Caspian (44 horses).  Caspian breed was  sampled from the Provinces of Alborz and Gilan. Kurdish breed was sampled from the Provinces of Kurdistan, Kermanshah, and Hamadan. Turkoman breed was sampled from the Provinces of Golestan, Markazi, and Isfahan. Multivariate analysis of variance (MANOVA) was implemented. In addition, Canonical Discriminate Analysis (CDA), Principal Component Analysis (PCA), and Custer analysis were executed for assessing the relationship among the breeds. All statistical analysis was executed by SAS statistical program. The results of our investigation represented the breeds classification into 3 different classes (Caspian, Turkoman, and Kurdish) based on different morphometrical traits. Caspian breed with smaller size in most variables was detached clearly from the others with more distance than Kurdish and Turkoman breeds. The result showed that the most variably trait for classification was Hind Hoof Length. Adaptation with different environments causes difference in morphology and difference among breeds. We can identify and classify domestic population using PCA, CDA, and cluster analysis.
三种伊朗马,土库曼,里海和库尔德,是最重要的伊朗马品种,因其美丽,多才多艺,耐力和智慧而闻名于世。表型表征是用来识别和记录不同品种内部和不同品种之间的多样性,基于它们的可观察属性。对土库曼(70匹)、库尔德(77匹)和里海(44匹)191匹纯种马进行了23个性状的表型表征和体生物学特征测定。里海品种的样本来自阿尔博尔斯省和吉兰省。从库尔德斯坦省、克尔曼沙赫省和哈马丹省取样库尔德犬种。土库曼品种的样本来自戈列斯坦省、马卡齐省和伊斯法罕省。采用多变量方差分析(MANOVA)。此外,采用典型判别分析(CDA)、主成分分析(PCA)和卡斯特分析(Custer)对品种间的相关性进行了评价。所有统计分析均采用SAS统计程序进行。我们的调查结果表明,根据不同的形态特征,将品种分为3个不同的类别(里海、土库曼和库尔德)。在大多数变量中体型较小的里海品种与其他品种的距离明显大于库尔德和土库曼品种。结果表明,对分类影响最大的性状是后蹄长。对不同环境的适应导致了形态的差异和品种间的差异。我们可以使用PCA、CDA和聚类分析来识别和分类国内人口。

The experiment  aimed to evaluate the production of nutrients  by different varieties of sorghum grown with high valuable indigofera legume  in intercropping system and to determine the suitable variety of sorghum that produced the highest nutrient in the system. The experiment was done at Jonggol Animal Science Teaching and Research Unit (UP3J) Jonggol, from November 2014 to March 2015. This experiment was conducted using completely randomized design with 2 factors (3 x 4) and 4 replications. The first factor was sorghum varieties (PATIR 3.2 (S1), PATIR 3.7 (S2), and CTY-33 (S3)). The second factor was indigofera composition (0% indigofera (I0), 30% indigofera (I1), 40% indigofera (I2), and 50% indigofera (I3)). Data were analyzed using analysis of variance and HSD test. There was no interaction among varieties of sorghum and indigofera composition. Indigofera population of up to 50%  in multiple cropping system had the highest (P<0.01) dry matter content, crude protein content, ash content, total fresh weight production, total dry weight production, total crude protein production, total ash production, and carrying capacity. Sorghum variety CTY-33 planted in multiple cropping system had  the highest (P<0.01) dry matter content, total dry weight production, and (P<0.05) total crude protein production. PATIR 37 sorghum variety planted in multiple cropping system had  the highest (P<0.05) ash content and (P<0.01) total ash production.  It is concluded that Indigofera population of up to 50% planted with different varieties of sorghum in multiple cropping system had  the highest nutrient production.
本试验旨在评价不同品种高价值豆科植物间作高粱的养分产量,确定间作制度下产量最高的适宜高粱品种。实验于2014年11月至2015年3月在钟果尔动物科学教学与研究单位(UP3J)钟果尔完成。试验采用完全随机设计,2因素(3 × 4), 4个重复。第一个影响因素是高粱品种(PATIR 3.2 (S1)、PATIR 3.7 (S2)和city -33 (S3))。第二个因素是靛蓝成分(0%靛蓝(I0)、30%靛蓝(I1)、40%靛蓝(I2)和50%靛蓝(I3))。采用方差分析和HSD检验对数据进行分析。高粱品种间与靛蓝成分间无交互作用。复种制度下50%以上的靛蓝群体干物质含量、粗蛋白质含量、灰分含量、总鲜重产量、总干重产量、总粗蛋白质产量、总灰分产量和承载能力最高(P<0.01)。复作高粱品种city -33的干物质含量、总干重和总粗蛋白质产量最高(P<0.05)。复作高粱品种PATIR 37灰分含量最高(P<0.05),总灰分产量最高(P<0.01)。综上所述,在不同品种高粱复种制度下,50%以上的靛蓝种群的养分产量最高。

The study to evaluate growth performance, nutrient digestibility, blood metabolites profile and meat fatty acid of Bali cattle treated with 3 different types of rations were conducted using a completely randomized block design with 4 replications. Ration treatments were R1: 40% native grass (NG) + 60% concentrate, R2: 40% NG + 60% concentrate supplemented with 5% soybean oil calcium soap (SOCS), and R3: (40% NG + 60% concentrate supplemented with 5% SOCS + 10% cashew fruit flour (CFF). Variables measured were growth performance, nutrients digestibility, blood metabolites, and meat fatty acid profile. Data were analyzed using analysis of variance (ANOVA) and the differences between treatment means were examined by Duncan Multiple Range Test. Results of the study showed that the 3 different feed treatments did not have any significant effect on dry matter intake and organic matter intake, daily body weight gain, feed efficiency, crude fiber, ADF and NDF digestibilities, cholesterol, triglycerides, low density lipoprotein (LDL), high density lipoprotein (HDL), total fatty acid contents and content of unsaturated and saturated meat fatty  acids of Bali cattle meat. Different treatment rations also did not affect dry matter digestibility, however the treatments significantly affect the organic matter, crude protein, and fat digestibility (P<0.05). Bali cattle fed 5% SOCS (R2) and 5% SOCS + 10% CFF (R3) had higher organic matter and ether extract digestibilities and linoleic acid content of meat (P<0.05) compared with the control (R1). The Bali cattle fed with R1 and R2 had higher crude protein digestibility (P<0.05) compared with that of R3. It is concluded that the supplementation of 5% SOCS and 10% CFF in the ration improved the digestibility of organic matter, ether extract and linoleic fatty acids content in Bali cattle meat.
采用4个重复的完全随机区组设计,研究了饲喂3种不同类型日粮的巴厘牛的生长性能、营养物质消化率、血液代谢物分布和肉脂肪酸。日粮处理为:R1: 40%天然草(NG) + 60%精料,R2: 40%天然草+ 60%精料添加5%大豆油钙皂(SOCS), R3: 40%天然草+ 60%精料添加5% SOCS + 10%腰果粉(CFF)。测量的变量包括生长性能、营养物质消化率、血液代谢物和肉脂肪酸谱。采用方差分析(ANOVA)对数据进行分析,采用Duncan多元极差检验检验处理手段之间的差异。结果表明,3种不同饲料处理对巴厘牛干物质采食量和有机物采食量、日增重、饲料效率、粗纤维、ADF和NDF消化率、胆固醇、甘油三酯、低密度脂蛋白(LDL)、高密度脂蛋白(HDL)、总脂肪酸含量以及不饱和和饱和肉脂肪酸含量均无显著影响。不同处理日粮对干物质消化率无显著影响,但对有机物、粗蛋白质和脂肪消化率有显著影响(P<0.05)。饲喂5% SOCS (R2)和5% SOCS + 10% CFF (R3)的巴厘牛肉质有机物和粗脂肪消化率及亚油酸含量均高于对照组(R1) (P<0.05)。饲粮R1和R2的巴厘牛粗蛋白质消化率高于饲粮R3 (P<0.05)。由此可见,日粮中添加5% SOCS和10% CFF可提高巴厘牛的有机物消化率、粗脂肪和亚油酸含量。

The crossbreeding between broiler and kampong chickens has been performed to develop a kampong-broiler strain chicken. The chicken stocking condition needs more attention as a part of animal welfare. This study was performed to identify the relationship between the stocking density and the stress based on Temperature Humidity Index (THI) and the effect of stocking density on meat quality, i.e., physical, microbiological, and organoleptic. Ninety DOCs of Kampong-Broiler (KB) were assigned into a completely randomized design with 3 treatments of stocking density  i.e., 8, 10, and 12 birds m-2. Each treatment was replicated 3 times. The experimental chickens were housed in 9 blocks of housing each with 1 x 1 m2 size. Data on physical and microbiology of meat qualities were analyzed with analysis of variance and continued with Duncan’s multiple range test. The organoleptic data were analyzed by using Kruskal-Wallis test. The result showed that the stocking density did not significantly affect the physical and hedonic quality of KB chicken’s breast. The stocking densities significantly affected (P<0.05) the microbiological variables of breast meat. The average value of THI during maintenance reached 28.98±1.25–29.33±1.32oC. The higher the animal density the higher the THI value that correlated to the stress condition. However, high stocking density did not affect the physical and hedonic quality of breast meat,  thus it can be accepted by the consumers. The higher the stocking density the higher the total plate count, Escherichia coli, and Staphylococcus aureus, without the presence of Salmonella sp. The meat quality of KB chickens raised in the stocking density of 10 birds m-2 meets the requirement of SNI 01-3924-2009.
将肉鸡与甘榜鸡进行杂交,培育出甘榜肉鸡品系。作为动物福利的一部分,鸡的饲养状况需要得到更多的关注。以温度湿度指数(THI)为基础,研究了放养密度与胁迫的关系,以及放养密度对肉质(物理、微生物和感官)的影响。选用90只棉肉鸡(KB),采用完全随机设计,饲养密度分别为8、10和12只m-2。每个处理重复3次。试验鸡饲养在9个鸡舍中,每个鸡舍的面积为1 × 1 m2。肉品质的物理和微生物学数据采用方差分析,并继续进行Duncan多元极差检验。采用Kruskal-Wallis试验对感官数据进行分析。结果表明,饲养密度对KB鸡胸肉的物理品质和享乐品质影响不显著。放养密度对胸肉微生物指标影响显著(P<0.05)。维持期间THI平均值为28.98±1.25 ~ 29.33±1.32℃。动物密度越大,与应激状态相关的THI值越高。然而,高放养密度并不影响胸脯肉的物理和享乐品质,因此可以被消费者接受。放养密度越高,培养皿总数、大肠杆菌和金黄色葡萄球菌越高,不存在沙门氏菌。在10只m-2的放养密度下饲养的KB鸡肉质符合SNI 01-3924-2009的要求。

The objective of this study was to show the risk factors affecting the conception rate in Holstein heifers after synchronization of estrus. A total of 275 Holstein heifers housed in a free barn were used for the experiment. The herd was visited regularly at four week intervals for synchronization of estrus using Heatsynch and CIDR-Heatsynch protocols. A group of four to 14 animals, depending on the availability, were referred to the experiment at each visit. Estrus induction rates in the two protocols were 93.9% and 94.9%, respectively. There was no difference in the conception rate between the two protocols. Conception rate after artificial insemination (AI) or embryo transfer (ET) were 46.3% and 51.4%, respectively. The risk factors affecting conception rate in heifers were daily weight gain (odds ratio [OR]= 4.673; P= 0.036) and body condition score (BCS) (OR= 3.642; P= 0.018). Furthermore, estrus synchronization protocol (OR= 1.774; P= 0.083) and the absence of corpus luteum (CL) at the initiation of treatment (OR= 0.512; P= 0.061) had a tendency to affect the conception rate, while age (OR= 0.715; P= 0.008) was a protective factor to conception rate.  In conclusion, positive daily weight gain before AI or ET, higher BCS, younger age, and the presence of CL at the initiation of estrus synchronization in dairy heifers increased the likelihood to conceive.
本研究旨在探讨影响荷斯坦小母牛同期发情后受孕率的危险因素。试验使用了275头荷斯坦小母牛,饲养在一个自由的谷仓里。采用Heatsynch和CIDR-Heatsynch协议,每隔4周定期回访牛群,同步监测发情情况。每次访问时,根据可用性,一组4到14只动物被转介到实验中。两种方案的发情诱导率分别为93.9%和94.9%。两种方案的受孕率无差异。人工授精(AI)和胚胎移植(ET)受精率分别为46.3%和51.4%。影响母牛受孕率的危险因素为日增重(优势比[OR]= 4.673;P= 0.036)和体况评分(BCS) (OR= 3.642;P = 0.018)。此外,发情同步方案(OR= 1.774;P= 0.083)和治疗开始时黄体(CL)缺失(OR= 0.512;P= 0.061)有影响受孕率的趋势,而年龄(OR= 0.715;P= 0.008)是影响受孕率的保护因素。综上所述,人工授精或体外授精前的日增重、较高的BCS、较年轻的年龄以及在发情同步开始时出现CL增加了奶牛怀孕的可能性。

This experiment aimed to determine nutrient content, protein fraction, and in vitro rumen fermentation of some alternative beans in comparison to soybean. Samples used were napier grass, soybean, redbean, groundnut, pigeonpea, cowpea, bambarabean, and mungbean. Samples were determined for their proximate composition, Van Soest’s fiber fraction, and Cornell protein fraction. The samples were subsequently evaluated for their fermentation characteristics and digestibility by using a two-stage in vitro rumen fermentation technique, maintained at 39 oC for 2 × 48 h. The in vitro incubation was performed in three consecutive runs by following a randomized complete block design in which each sample per run was represented by four fermentation tubes. Results revealed that all experimental beans contained high crude protein (CP), i.e. above 200 g/kg dry matter (DM), but only soybean and groundnut had CP contents higher than 300 g/kg DM. Redbean had the lowest crude fiber and acid detergent fiber contents among the beans. Soybean contained high proportion of rapidly degraded CP fraction, but low in slowly degraded and unavailable CP fractions. High proportion of slowly degraded CP fraction was found in redbean and bambarabean. Redbean, pigeonpea, cowpea, and mungbean were better than soybean, groundnut, and bambarabean with regard to DM degradability and DM digestibility values (P<0.05). Concentration of total VFA was the highest in the incubation of redbean. It was concluded that groundnut, redbean, pigeonpea, cowpea, and mungbean have the potency to be used to substitute soybean for ruminant feeding.
本试验旨在比较几种替代大豆的营养成分含量、蛋白质含量和体外瘤胃发酵量。所使用的样品有甘草酸、大豆、红豆、花生、鸽豆、豇豆、竹豆和绿豆。样品的近似组成、Van Soest纤维组分和Cornell蛋白组分被确定。随后,采用两阶段体外瘤胃发酵技术,在39℃下保持2 × 48小时,评估样品的发酵特性和消化率。按照随机完全区组设计,连续三次进行体外培养,每次培养的样品由四个发酵管代表。结果表明,试验大豆的粗蛋白质含量均在200 g/kg干物质(DM)以上,但只有大豆和花生的粗蛋白质含量高于300 g/kg干物质,粗纤维和酸性洗涤纤维含量最低的是红豆。大豆中快速降解粗蛋白质的比例较高,缓慢降解和不可用粗蛋白质的比例较低。在红豆和竹豆中发现了高比例的慢降解CP。红豆、鸽豆、豇豆和绿豆的干物质降解率和消化率均优于大豆、花生和竹豆(P<0.05)。总VFA浓度以红豆孵育时最高。结果表明,花生、红豆、鸽豆、豇豆和绿豆具有替代大豆作为反刍动物饲料的潜力。

The research was conducted to evaluate embryo development, post-hatch performances, and growth rate of kampung chicken treated in-ovo feeding of L-Arginine. A total of 135 kampung chicken fertile eggs (weight 42-43 g) were used and divided into 5 treatment groups of three replications. They were placed in the semi-automatic incubator. The first group was without in-ovo feeding (negative control); the second group was in-ovo feeding of saline 0.9% (positive control); the 3, 4, and 5 groups were in-ovo feeding of 0.5, 1.0, and 1.5% L-Arginine, respectively. In-ovo feeding of L-Arginine were injected into albumen on day 10 of incubation period using automatic syringe in the narrow end side of egg by inserting needle through a small hole at 10 mm depth. After hatching, all day old chicks were placed in floor pens (1 x 0.5 x 0.5 m) accordance with the previous egg groups. The results showed that in-ovo feeding of L-Arginine increased weight and circumference of the embryo, but did not affect the length of embryo. In-ovo feeding of L-Arginine resulted in a higher body weight gain and a lower feed conversion even though feed intake was not significantly different compared to the control groups. The growth rate performance up to 6 weeks rearing increased significantly by increasing L-Arginine administration to 1.0%. It can be concluded that embryo development and post-hatch performances of kampung chicken were markedly increased by in-ovo feeding of L-arginine.
本试验旨在评价在蛋内饲喂l -精氨酸后甘蓬鸡的胚胎发育、孵化后生产性能和生长速度。选取135枚体重42 ~ 43 g的甘丰鸡受精卵,分为5个处理组,每组3个重复。它们被放置在半自动培养箱中。第一组不进行卵内饲养(阴性对照);第二组在蛋内饲喂0.9%生理盐水(阳性对照);3、4、5组分别饲喂0.5、1.0、1.5% l -精氨酸的蛋内饲料。在孵育期第10天,用自动注射器将l -精氨酸注射到鸡蛋窄端侧的蛋白中,针头穿过10 mm深的小孔。孵化后,将日龄雏鸡按之前的蛋组放置在1 × 0.5 × 0.5 m的落地式围栏中。结果表明:卵内饲喂l -精氨酸可增加胚重和周长,但对胚长无影响。尽管采食量与对照组相比无显著差异,但在蛋内饲喂l -精氨酸导致了更高的增重和更低的饲料系数。当l -精氨酸添加量为1.0%时,6周前的生长性能显著提高。由此可见,在蛋内饲喂l -精氨酸可显著提高甘榜鸡的胚胎发育和孵化后生产性能。

Durian seed flour contains starch consisted of amylose and amylopectin like tapioca flour, so it can be utilized as a filler in meatball production. The purposes of this research were to evaluate the nutrient content and quality of durian seed flour, the best level of durian seed flour addition to the meatball production, and the quality of beef meatball during storage in room temperature and refrigerator. Complete randomized design (CRD) was used with 3 treatments and 3 replications. The treatments used different filler ingredients consisted of: 1) 100% tapioca, 2) 50% tapioca + 50% durian seed flour, and 3) 100% durian seed flour utilization. The results showed that durian seed flour could affect the protein levels and hardness of beef meatballs. In the organoleptic test, the addition of durian seed flour had no effect on the appearance of the color, flavor, aroma, and texture. The meatballs with 100% durian seed flour had the lowest hardness. The protein content of the meatballs with 100% durian seed flour was the highest. The used of 50% durian seed flour gave the best effect to beef meatball during storage. Meatball could be stored up to 8 h in room temperature while refrigerator could keep it longer up to 12 d. It was concluded that the addition 50% durian seed flour may substitute tapioca flour as filler ingredient of beef meatball.

Glycerol or glycerin is generally recognized as a safe compound to be used in animal feed, especially for ruminants. A number of in vitro studies related to glycerol supplementation in ruminant ration have been published but to date the results have not been summarized. The objective of this study was, therefore, to evaluate in vitro digestibility, ruminal fermentation characteristics, total gas and methane production through the meta-analysis approach. Meta-analysis was applied to 13 experiments and 42 treatments dealing with glycerol supplementation in ruminants. Data were analyzed by general linear model procedure in which the glycerol levels and the different studies were treated as fixed effects. Results revealed that glycerol supplementation did not affect the in vitro digestibility and total VFA production, but significantly decreased molar proportion of acetate and iso-valerate (P<0.05). In contrast, molar proportion of propionate, butyrate, and valerate significantly increased, and thus the ratio of acetate to propionate declined linearly (P<0.05). Methane production decreased linearly and accompanied with an increase of total gas production with increasing levels of glycerol supplementation (P<0.05). It is concluded that the use of glycerol as an energy substitution in animal feed has no detrimental effects in the rumen and environmentally friendly.
甘油或甘油通常被认为是一种安全的化合物,可用于动物饲料,特别是反刍动物。一些关于在反刍动物日粮中添加甘油的体外研究已经发表,但迄今为止尚未对结果进行总结。因此,本研究的目的是通过荟萃分析方法评估体外消化率、瘤胃发酵特性、总气体和甲烷产量。对反刍动物添加甘油的13个试验和42个处理进行meta分析。数据通过一般线性模型程序进行分析,其中甘油水平和不同的研究被视为固定效应。结果显示,添加甘油对体外消化率和总VFA产量无显著影响,但显著降低了乙酸和异戊酸的摩尔比(P<0.05)。丙酸、丁酸和戊酸的摩尔比显著升高,乙酸/丙酸呈线性下降(P<0.05)。随着甘油添加水平的增加,甲烷产量呈线性下降趋势,并伴有总产气量的增加(P<0.05)。综上所述,在动物饲料中使用甘油作为能量替代品对瘤胃无不良影响,且环境友好。
