: Colostrum volume after calving, transition and mature milk outputs in the time from 1 st to 10 th milkings were evaluated at 30 primiparous and 30 multiparous cows milked twice daily. Colostrum volume at the first milking after calving varied from 1.5 to 19.2 kg (mean 9.44 ±5.6 kg SD) in multiparous and from 1.2 to 9.8 kg (mean 5.65 ± 2.3 kg SD) in primiparous cows. Timing of the first milking did not negatively influence colostrum volume. Colostrum volume of the second milking decreased over all multiparous and primiparous cows because the period of time between first and second milking was shorter (10.5 hours). The hourly milk outputs increased sharply from the second to the fourth milking in multiparous and primiparous Holstein Friesian cows. Applying a linear regression model we observed a significant large positive relationship between volume of colostrum at first milking and subsequent transition and mature milk outputs from 2 nd to 10 th milkings. A low colostrum volume secreted was identified in multiparous cows, as a results of sorter dry period and in primiparous cows, probably as a result of low secretory capacity of mammary gland. Extended feeding with transition milk can be real health benefits for the newborn calf.
对30头每日两次挤奶的初产奶牛和30头多产奶牛进行产犊后初乳体积、转乳量和成熟产奶量的测定。产犊后首次挤奶初乳量,多产奶牛为1.5 ~ 19.2 kg(平均9.44±5.6 kg SD),初产奶牛为1.2 ~ 9.8 kg(平均5.65±2.3 kg SD)。第一次挤奶的时间对初乳量没有负面影响。由于第一次和第二次挤奶之间的时间较短(10.5小时),第二次挤奶的初乳量在所有多产奶牛和初产奶牛中都有所减少。多产和初产荷斯坦弗里西亚奶牛的每小时产奶量从第二次到第四次挤奶急剧增加。应用线性回归模型,我们观察到第一次挤奶时的初乳体积与随后的过渡和第2次至第10次挤奶的成熟产奶量之间存在显著的正相关关系。经鉴定,多胎奶牛的初乳分泌量较低,可能是由于乳腺分泌能力较低所致。长时间用过渡奶喂养对新生小牛的健康有益。

: Atropine is one of the commonly used drugs for clinical treatment of livestock and poultry, as well as one of the commonly used drugs for animal emergency treatment. Its main components are d-hyoscyamine and L-hyoscyamine. Atropine is a toxic colorless, odorless or white crystalline alkaloid extracted from belladonna and other solanaceous plants. It is neutral or weakly acidic when dissolved in water. Atropine is mainly an m-receptor blocker, belonging to anticholinergic drugs. It can compete with acetylcholine for M-choline receptor, thus blocking the M-like effect of acetylcholine. Atropine has a very high selectivity in blocking M receptor, and large doses can also block ganglion N1 receptor. It mainly acts on smooth muscle, relieves small vessel spasm, improves microcirculation, inhibits gland secretion, relieves vagus nerve inhibition on heart, accelerates heart beat, dilates pupils, increases intraocular pressure, excites respiratory center, and relieves respiratory inhibition. It is applied to cases of ruminant diseases such as diarrhea in calves and lambs, toxic diseases in organic phosphorus, abdominal pain caused by parasitic diseases, gastrointestinal volvulus, administration before anesthesia, improvement of microcirculation, eye diseases, etc. through oral, subcutaneous, intramuscular and intravenous injection. However, the amount of treatment has no significant effect on blood vessels and blood pressure. A large dose of treatment can cause skin blood vessels to expand. A large dose of treatment can relieve small vessel spasm when microcirculation is impaired, and expand peripheral blood vessels to improve microcirculation.
:阿托品是畜禽临床治疗常用药物之一,也是动物急救常用药物之一。其主要成分为d-山莨菪碱和l -山莨菪碱。阿托品是一种有毒的无色、无味或白色结晶生物碱,从颠茄和其他茄属植物中提取。溶于水时呈中性或弱酸性。阿托品主要是m受体阻滞剂,属于抗胆碱能药物。它能与乙酰胆碱竞争m -胆碱受体,从而阻断乙酰胆碱的m样作用。阿托品阻断M受体的选择性非常高,大剂量也可阻断神经节N1受体。主要作用于平滑肌,缓解小血管痉挛,改善微循环,抑制腺体分泌,缓解迷走神经对心脏的抑制,加速心跳,扩大瞳孔,升高眼压,兴奋呼吸中枢,缓解呼吸抑制。适用于犊羊腹泻、有机磷中毒、寄生虫病腹痛、胃肠扭转、麻醉前给药、微循环改善、眼疾等反刍动物疾病的口服、皮下、肌内、静脉注射。然而,治疗的量对血管和血压没有明显的影响。大剂量的治疗会导致皮肤血管扩张。大剂量治疗可缓解微循环受损时的小血管痉挛,扩张周围血管,改善微循环。

: In Cambodia, pig raising plays an important role as it provides meat and also increasing family income. Currently, researchers are trying to find the feeds that focus on using locally available natural resources as animal feeds can be used to reduce the cost of expensive feed on market such as soybean or fish meal. Based on that one experiment was designed and conducted at the campus of Svay Rieng University from 01 st April to 15 th September 2022, sited in NR 1, Sangkat Chek, Svay Rieng City, Svay Rieng Province. The aim of this experiment was to compare the feed intake of sows, the piglet performance in lactation, and the reproductive traits after weaning. Twelve sows were assigned according to Completely Randomized Design (CRD) within 3 treatments and 4 replications. The treatments of experiment were RW0, RWB20, and FM10. The results of the experiment were found that the total of feed intake in dry matter (DM) during pregnancy and lactation, were higher significantly different for the treatment of RWB20 (P < 0.01). There were no effects of all treatments on parameters in total litter size, mortality and total litter size live born of piglet performance at birth, except for total litter weight and mean live weight which was higher significantly different for RWB20 (P < 0.01). Non-significant different among the treatments on parameters in total litter size, mortality and mean piglet live weight at 21 days, except for total litter weight and litter weight change for RWB20 (P<0.01). There were higher significantly different for treatment of RWB20 in total litter size, total litter weight, litter weight change and mean piglet live weight at 45 days (P < 0.01). And there were no effects among the treatments on parameters in weaning to estrus, cycle of reproduction and number of litters per year in reproduction traits. However, length of pregnancy was higher significantly different for RWB20 (P < 0.01). It is concluded that a mixture of ensiled taro (10%) and rice wine by product (20%) were higher increased on feed intake of sows in pregnancy and lactation stages, higher increased on total litter size, total litter weight, litter weight change and mean piglet live weight in lactation period, and better effects on reproductive traits in weaning to estrus, cycle reproduction and number of litters per year. Using protein from a mixture of the ensiled taro and rice wine by product could successfully reduce the cost of pig feeds.
在柬埔寨,养猪起着重要的作用,因为它提供肉类并增加家庭收入。目前,研究人员正试图找到一种饲料,专注于利用当地可用的自然资源作为动物饲料,可以用来降低市场上昂贵的饲料(如大豆或鱼粉)的成本。在此基础上,于2022年4月1日至9月15日在世青大学校园设计并进行了一项实验,实验地点位于世青省世青市Sangkat Chek第1区。本试验旨在比较母猪采食量、仔猪哺乳期生产性能和断奶后的繁殖性状。12头母猪按完全随机设计(CRD)分为3个处理,4个重复。试验处理为RW0、RWB20和FM10。试验结果发现,妊娠期和哺乳期干物质(DM)总采食量在RWB20处理下均显著高于对照组(P < 0.01)。除总窝重和平均活重以RWB20为极显著差异(P < 0.01)外,各处理对仔猪出生时生产性能的总窝重、死亡率和总窝重参数均无影响(P < 0.01)。除RWB20的窝重和窝重变化外,各处理仔猪21日龄窝重、死亡率和平均活重均无显著差异(P<0.01)。45日龄时,RWB20处理的窝重、窝重、窝重变化和仔猪平均活重差异极显著(P < 0.01)。各处理对断奶发情、繁殖周期、年产仔数等繁殖性状无显著影响。RWB20组妊娠期长短差异有统计学意义(P < 0.01)。综上所述,青贮芋头(10%)与黄酒副产物(20%)的混合饲粮对妊娠期和哺乳期母猪采食量有较高的提高,对哺乳期母猪总窝重、窝重变化和平均仔猪活重有较高的提高,对断奶至发乳繁殖性状、周期繁殖和年窝数有较好的影响。利用青贮芋头和米酒副产品的混合物中的蛋白质可以成功地降低猪饲料的成本。

: Major histocompatibility complex is the gene complex that exists in all vertebrae like humans (HLA), dogs (DLA), bovine (BLA), ovine (OLA), swine (SLA), and equine (ELA). MHC possesses three regions (I, II, III) that control major specific immune responses and contain variety of genes which influence growth, development, reproduction, odor, and olfaction. Measuring levels of polymorphism of these genes can provide indirect measures of the immunological fitness of populations. As humans and mice, cattle have three MHC gene classes (class I, II, and III). Both BoLA class I and II play a role in antigen presentation, however the function of BoLA class III has been releated with components of the complement system. BoLA class II region is extra separated into class IIa and class IIb. In this gene, the genetic polymorphism of class II α and β genes occurs predominantly in exon 2 encoding the antigen binding site. The BoLa-A locus has 32 serologically defined alleles and minimum four further putative alleles in addition to a high frequency of null alleles. With association allele hold DRB3.2*8 (DRB3*1201) and DRB3.2*16 (DRB3*1501) genes are associated with mastitis susceptibility, and DRB3.2*22 (DRB3*1101), DRB3.2*23 (DRB3*2703) and DRB3.2*24 (DRB3*0101) with mastitis resistance. The A8 specificity and the EIAY sequence are significant markers of resistance, while the serine residue is a marker of susceptibility to dermatophlosis. According to the report 2004, BoLA-DRB3 alleles with the amino acid residues Glu, Arg, and valine (Val) at positions 74, 77, and 78, respectively, give resistance to tumor development by BLV infection. On the other hand, HaeIII CC and HaeIII BC genotypes were actually associated with resistance to FMD in contrast, the HaeIII AA genotype was associated with susceptibility to FMD. Another report on infected Egyptian buffaloes with serotype O FMDV genotype AA for FMD resistance while genotype AC for susceptibility to FMD.
主要组织相容性复合体是存在于所有椎骨中的基因复合体,如人类(HLA)、狗(DLA)、牛(BLA)、羊(OLA)、猪(SLA)和马(ELA)。MHC拥有三个区域(I、II、III),控制主要的特异性免疫反应,并包含多种影响生长、发育、繁殖、气味和嗅觉的基因。测量这些基因的多态性水平可以间接测量群体的免疫适应性。与人类和小鼠一样,牛有三种MHC基因(ⅰ类、ⅱ类和ⅲ类)。ⅰ类和ⅱ类都在抗原呈递中起作用,而ⅲ类的功能与补体系统的成分有关。BoLA II类区域额外分为IIa类和IIb类。在该基因中,II类α和β基因的遗传多态性主要发生在编码抗原结合位点的外显子2上。BoLa-A基因座有32个血清学上确定的等位基因,除了高频率的空等位基因外,还至少有4个推测等位基因。带关联等位基因的DRB3.2*8 (DRB3*1201)和DRB3.2*16 (DRB3*1501)基因与乳腺炎易感性相关,DRB3.2*22 (DRB3*1101)、DRB3.2*23 (DRB3*2703)和DRB3.2*24 (DRB3*0101)基因与乳腺炎耐药相关。A8特异性和EIAY序列是耐药的重要标志,丝氨酸残基是对皮肤病的易感性标志。根据2004年的报告,BoLA-DRB3等位基因的氨基酸残基Glu、Arg和valine (Val)分别位于第74位、第77位和第78位,可以抵抗BLV感染导致的肿瘤发展。另一方面,HaeIII CC和HaeIII BC基因型实际上与口蹄疫抗性相关,而HaeIII AA基因型与口蹄疫易感性相关。另一份感染埃及水牛的报告,血清O型FMDV基因型AA对口蹄疫产生抗性,而基因型AC对口蹄疫产生易感性。

The present study was conducted from April 2015 up to the end of November 2015 in the west Hararghe Zone, Oromia region, Eastern part of Ethiopia in and around Anchar district with the aim to determine or to know the prevalence of bovine fasciolosis in and around Anchar and to recommend the controlling method of fasciolosis in study area. The method employed in the study area was sedimentation technique. A total of 385 were selected randomly from the study populations and from the total examined 79 (20.5%) cattle were positives for fasciolosis. The recorded fasciolosis prevalence was varying from 18.9% to 25.5% in the different sites of the study area and the overall prevalence rate of 20.8. The prevalence of disease in age (young) 2.45% and Adult 28, 89% Sex (Male) 1.63% and female 37.81% and body condition (poor) 22.1% and 19.46% was recorded. Infection rate different age, sex, site and body condition of animal showed not statistically significant different. Therefore, it is possible to conclude that fasciolosis is the prevalent diseases in the study area, and the disease need due consideration both from the livestock owner and the veterinarian, in the light of present study. Finally, a few points of recommendation were forwarded to alleviate the problems of fasciolosis in this area.
本研究于2015年4月至11月底在埃塞俄比亚东部奥罗米亚州西部哈拉尔河区及安恰尔区及其周边地区进行,目的是确定或了解安恰尔区及其周边地区牛片形虫病的流行情况,并提出研究区片形虫病的防治方法。研究区采用的方法为沉积法。从研究人群中随机选择了385头牛,其中79头(20.5%)呈片形吸虫病阳性。研究区不同地点的片形吸虫病流行率为18.9% ~ 25.5%,总流行率为20.8%。年龄(年轻)2.45%,成人28.89%,性别(男性)1.63%,女性37.81%,体质(差)22.1%,19.46%。不同年龄、性别、部位、体况的动物感染率差异无统计学意义。因此,可以得出结论,片吸虫病是研究地区的流行疾病,根据目前的研究,家畜主和兽医都需要对疾病进行适当的考虑。最后,提出了几点建议,以缓解该地区的片形虫病问题。
