  This study was to evaluate the effects of several Chinese processing methods by steaming,boiling,braising,pan-frying,frying,roasting,drying on eating quality of beef.The shear force,color and TPA (hardness,chewiness,springiness,cohesiveness and resilience) were used to evaluate the eating quality of beef comprehensively.The results indicated that each of these Chinese style processing methods had a significant influence on the eating quality.The shear force values in the process of steaming,boiling,pan-frying,roasting and drying groups were significantly higher than in the raw group (P<0.05).The variation between a* and L*values showed opposite trend,all processed groups were reduced gradually for a* values and clearly distinguished from the raw group (P<0.05).The b* values in the process of steaming,boiling and braising groups were significantly higher while the drying group was lower than in the raw group (P<0.05).We also found that the effects of most processing methods on hardness and chewiness of beef were significant (P<0.05),the highest value was 40862.51 g at the dried group,the lowest value was 8684.92 g at the raw group.When it comes to springiness and cohesiveness values,there were significant difference between processed and raw groups (P<0.05).Resilience showed a significant difference between processed and unprocessed groups except steamed group.A comprehensive analysis revealed that raw beef maintained higher eating quality than steamed,braised and fried.These data can be used to provide a theoretical basis for consumers to choose a reasonable and scientific processing method with good eating quality.

本文主要通过益生菌基本定义的概述,对今后益生菌发展方向的阐述,发现益生菌在今后发展过程中遇到的困难进行综述,同时将益生菌种类进行了总结归纳并对益生菌在畜禽养殖中的意义做了充分的分析与总结,使得我们今后在畜禽养殖中对益生菌的使用有了更深层次的理解.
文章通过所见所闻的实例,谈环境因素对猪群生长影响.猪场(舍)环境因素主要是指温度、湿度、气流、病源微生物、有害气体、灰尘、光照和噪音.在养猪生产中,品种、饲料、防疫、环境因素是影响猪健康生长,决定养猪生产水平高低的主要因素.它们相互影响和制约.当品种、饲料、防疫问题基本解决后,环境因素对于养猪业饲养经济效益起决定作用.但在实际的生产中,有些养殖户不注重环境条件的管理和建设,主要表现为场址选择不正确
星状病毒(Astrovirus,AstV)是一类广泛存于在人等31种哺乳类和6种禽类的动物体内的病毒.该病毒常常与其他的病毒混和感染宿主导致的严重的病症,该病毒基因组存在变异性高的情况,在不同物种间的基因重组现象也不断被发现.通过对猪星状病毒衣壳蛋白的抗原特性研究,利用猪星状病毒PAstV1-GX1分离株(GenBank:KF787112)ORF2高变区编码的重组蛋白PET-C做为包被抗原,利用制
广西南宁某规模化猪场近期暴发疫情,临床表现为断奶仔猪发热,喘气,腹式呼吸,关节肿大.剖检发现病猪胸腔积液,心脏呈现"绒毛心"症状以及肿大关节有粘液.通过实验室检测发现该猪场蓝耳病抗体水平离散度高,从病猪身上可以检测到蓝耳病病毒,分离的细菌经鉴定为血清5型副猪嗜血杆菌,且出现了一定程度的耐药现象.该病例是由于猪场免疫效果不理想以及断奶转群等因素造成的蓝耳病和副猪嗜血杆菌病混合感染,提醒应注意蓝耳病的
