2018年非洲猪瘟疫情出现以来,全国及黑龙江省生猪生产、猪肉市场受到了较大的影响,生猪、能繁母猪存栏减少,生猪出场价格也经历了明显波动。2019年春节以后,随着省外调出量增加和猪源减少,黑龙江省生猪出场价格进入上升通道,超过了全国平均水平,白条猪肉批发价格和猪肉市场零售价格随之上行。通过对2019年黑龙江省生猪生产环节、屠宰加工环节、猪肉市场零售环节进行调研,对生猪出场价格、白条猪肉批发价格、猪肉零售价格、生猪和能繁母猪产能等指标进行分析,阐述了以生猪和猪肉市场为重点的肉类产销形势,为促进肉类产业高质量发展、提高市场保供能力提供参考。 相似文献

<正>非洲猪瘟疫情自去年8月在国内首次爆发至今已将近8个月,生猪养殖行业遭遇了冰火两重天。从最初的养殖户恐慌性抛售至2019年1月中旬,生猪价格刷新了2006年以来的历史低点。然而,在生猪产能遭受重创的主要因素作用下,生猪价格开始爆发性上涨,开启了本轮猪肉价格的"牛市"。预计2019年度猪肉产量将下降15%-20%,猪价有望刷新历史高点。另外,由于疫情严重影响到种猪产能,本轮猪 相似文献

<正>受非洲猪瘟等多重因素影响,国内生猪产能下滑冲击了整个养猪业,而国民猪肉主导型的消费习惯并没有发生变化,供需失衡引发了猪价强烈反弹。今年3月以来,我国猪肉价格持续上涨,屡创历史新高。为稳定猪肉价格,保障重大节假日肉类供应,9月19日、9月26日、9月29日,华商储备商品管理中心三次出手,通过竞价交易的方式,累计向市场投放3万吨冻猪肉。之后,我国生猪价格基本平稳, 相似文献

正纵观各大生猪养殖上市公司今年上半年的业绩,由于受到非洲猪瘟等因素影响,除了极少数企业外,大部分上市猪企均出现不同程度的亏损。另据农业农村部监测,截至9月6日14:00时,全国农产品批发市场猪肉平均价格为35.12元/公斤,与8月2日全国农产品批发市场猪肉平均价格24.48元/公斤相比上涨超过10元/公斤。随着生猪和猪肉价格不断上涨,在大部分上市猪企从第二季度开始步入盈利期的同时,行业也在加速洗牌。 相似文献

非洲猪瘟(ASF)是由非洲猪瘟病毒引起的一种急性烈性高接触性传染病,其发病过程从急性、亚急性、慢性发病不等,其临诊特征是高热、皮肤发绀,各内脏器官出血,同时伴有呼吸障碍和神经症状,发病率和死亡率几乎可高达100%。该病在临床上与其他败血性、出血性疾病极其类似其死亡的几率都相对较高;非洲猪瘟的出现严重的影响了生猪行业的发展,已经对养猪业产生极大的危害,从饲料加工、生猪养殖、生猪屠宰、肉品零售到肉制品加工全产业链均受到了严重的影响。简要的分析了非洲猪瘟发生的起源、流传以及在国内的现状,剖析了应该采取何种手段进行防控,来抑制住非洲猪瘟的扩散。 相似文献

近年来,在全世界范围内由非洲猪瘟病毒引发的猪瘟疫情屡见报道,并呈现频率高、影响范围广和持续时间长的特征。猪肉及其制品是我国居民消费量最大的动物蛋白质,非洲猪瘟疫情的持续爆发严重打击了消费者的消费耐心,极大阻碍了生猪养殖和猪肉制品加工产业的发展,带来了严重负面影响。该文通过对非洲猪瘟病毒、传播途径、鉴定方法和疫苗研究等方面的分析,结合我国生猪养殖产业和畜产品消费的现状等因素,提出了可行的控制措施。针对非洲猪瘟病毒及其疫情的控制,该文认为通过控制传染源、切断传播途径和采取适当措施保护生物群体,并建立长效运行机制,实现对实施过程的监督和管理。通过多维度、多层次控制措施的实施能够抑制疫情的大面积爆发,将有力保护猪肉制品生产安全,但是彻底消灭非洲猪瘟病毒需要所有国家的有效合作,将是一个十分漫长艰辛的过程。 相似文献

The spread of African swine fever virus (ASFV) leads to high mortality in domestic pigs, and has caused huge losses in the global pork industry. Therefore, the rapid detection of ASFV is essential for the prevention and control of the epidemic. Herein, a denaturation bubble-mediated strand exchange amplification (SEA) with colorimetric detection strategy for the rapid detection of ASFV was established and the results were visible with the naked eyes. The entire detection process based on isothermal amplification was performed on a portable metal bath only. And the whole process including rapid extraction and visual detection was finished within 50 min. The limit of detection of this method reached to 104 copies/μl of plasmid containing p72 gene. And the ASFV was successfully detected in eight different tissue and seven types of pig feed which revealed a strong anti-interference ability in the presence of complex matrix. Through comparing 94 field positive and negative ASFV samples, excellent performance of SEA assay with 92.86% sensitivity and 100% specificity relative to PCR was observed. The developed method could be used for on-site detection of ASFV with simplicity, rapidity, and visuality, especially suitable for pork industry food safety and ASFV control in resource-limited areas. 相似文献

为比较瘦肉型的杂交商品猪肉和本地猪肉对湖南腊肉品质的影响,实验选取三元杂交商品猪的背最长肌(A)和腹部五花肉(B)、本地宁乡猪的背最长肌(C)和腹部五花肉(D)为原料加工湖南腊肉。测定了加工过程中腊肉理化指标变化和腊肉的颜色、挥发性性成分等。实验结果表明:在腊肉成品中,相同部位原料肉加工的腊肉,杂交商品猪肉的水分含量显著高于宁乡猪加工的腊肉样品(AC,BD),但食盐含量和亚硝酸盐含量呈现相反的变化趋势,即商品杂交猪肉腊肉具有较低的食盐含量和亚硝残留量(AC,BD);4组实验腊肉样品中,L*值均呈下降趋势,两个品种的猪肉中背最长肌的a*值呈现先下降后上升趋势,腹部五花肉的变化规律不明显;样品A、B、C、D分别鉴定出挥发性成分40种、24种、54种、23种。说明了不同原料肉品种和不同部位对湖南腊肉的品质有一定影响。 相似文献

对火毛撒坝猪、高黎贡山猪、杜洛克猪的生长性状、胴体性能、肉质性状进行比较,为云南两个优质地方猪种的保护与开发利用提供理论依据。试验饲养火毛撒坝猪、高黎贡山猪、杜洛克猪各10头(5♂,5♀),至260日龄随机屠宰各猪种6头(3♂,3♀),测定其生长性状、胴体性能、肉质性状、肌肉组织学特性、脂肪酸、氨基酸和胆固醇,并进行显著性比较分析。结果说明:高黎贡山猪猪肉风味、口感更好,营养价值更高;火毛撒坝猪胆固醇含量低,保健性能更佳,但沉脂率强,在饲养方式上有待改进;杜洛克猪仍保持外来猪种的特性,但鲜味氨基酸和总氨基酸含量比火毛撒坝猪高,还需进一步研究。 相似文献

Pigs and pork meat products are often causes of Salmonella in humans. Salmonella can enter the human food chain at any part of the meat production process. Contamination of pork can be reduced by lowering the contamination of pigs at primary production. Production of “Salmonella free pigs” will reduce the risk of this zoonozis in people. It is possible to determine the serological status of pig farms. Prevention of Salmonella in humans should aim at: prevention of entrance of Salmonella to the pig farm, reduction of the number of infected animals and stopping the spreading of microorganism. 相似文献

The meat quality of halothane heterozygotes (Nn) was investigated using British Landrace (n = 18) and Landrace × Large White pigs (n = 67). Normal and PSE meat were identified in both breeds using M. longissimus dorsi (LD). In Landrace × Large White Nn pigs, the potential meat quality identified using small biopsy LD samples (500 mg) showed a wide spectrum in water-holding capacity (WHC), ranging from normal (43%) to PSE (57%). Predictions of meat quality in live pigs were confirmed from post-mortem assessments of LD samples based on pH(1) and fibre optic probe measurements. Our results show that Nn pigs have the propensity to produce a higher proportion of PSE than normal carcasses. The predictive meat quality test performed on small biopsy LD samples offers an opportunity not currently available to the pig industry, to select Nn pigs with the potential to produce pork of superior WHC. 相似文献

Variation is inherent to living systems. Because feeding strategies are applied to groups of pigs, it contributes to the inefficient use of natural resources and may even amplify the variation among pigs at slaughter. Precision pork production and precision feeding, through management of the variation among individuals, may contribute to improving the efficiency of animal production systems. This approach relies on the prediction of the response of the animal to the nutrient supply, the continuous monitoring of the response, and a system to control nutrient supply. Most nutritional models of pig growth are based on the partitioning of nutrients between energy expenditure, and protein and lipid deposition. However, the link between chemical body composition and tissue growth, tissue composition and thus carcass quality remains a challenge in modeling. The potential of precision pork production also depends on the (real-time) information that can be obtained to control growth and carcass quality. 相似文献
