Qian DONG,Huiying LIU,Xinyun LI,Wei WEI,Shuhong ZHAO,Jianhua CAO

《农业科学与工程前沿（英文）》 2014年第1卷第2期页码 137-143 doi: 10.15302/J-FASE-2014014

摘要： Meat quality is an important trait in the pig industry. To identify genomic regions and haplotype blocks responsible for meat quality traits in pigs, a genome-wide association study was conducted for five traits including intramuscular fat content, pH at 45 min and 24 h, drip loss within 24 h and water-holding capacity in 231 Yorkshire barrows using illumina porcine 60k SNP chips. The results showed that a total of 344 single nucleotide polymorphisms (SNP) were significantly associated with five meat quality traits ( <1×10 ). Moreover, 323 SNPs were within the reported QTL regions, of which 21 were novel. Also, 158 SNPs fell into the proximal region of meat quality related genes. In addition, 25 haplotype blocks based on 116 SNPs were revealed with SNP combination patterns for five traits. Our study added new SNP information for identification of meat quality traits in pigs and will help elucidate the mechanisms of meat quality in pigs.

Mohammod Abdul HAMID,Xi WANG,Xiangdong DING,Chuduan WANG,Xingbo ZHAO

《农业科学与工程前沿（英文）》 2014年第1卷第3期页码 236-241 doi: 10.15302/J-FASE-2014034

摘要： Pig meat off-flavor is attributed to trimethylamine (TMA) concentration, and it is considered as the precursor of the fishy off-flavor problems. In this study, TMA concentrations in pig meat were determined, and the interactions with breed and gender effects were discussed. In addition, the TMA threshold for meat off-flavor and pig meat natural quality was measured in relation to meat storage and movement, and the influential factors including the pig breed and storage time were discussed. The results indicated positive effects on the precursor of the fishy off-flavor and the TMA threshold. Native breeds were found to have lower TMA concentrations than European breeds ( <0.01), and females and castrated males had significantly lower TMA concentration than males ( <0.01), The threshold concentration of TMA when meat was classed as off-flavored was 25 μg·g , and this occurred after 35–38 h of storage. The natural qualities, such as appearance, flavor, color and overall acceptable scores declined significantly after 4 days in storage ( <0.01). It is concluded that pig meat off-flavor, breed and gender were essential factors affecting flavor for meat breeding programs, and storage time is important for pig meat natural quality.

Guangxue WU , Zhenhu HU , Mark G. HEALY , Xinmin ZHAN ,

《环境科学与工程前沿（英文）》 2009年第3卷第3期页码 300-306 doi: 10.1007/s11783-009-0031-6

摘要： Since the solubilization of meat and bone meal (MBM) is a prerequisite in many MBM disposal approaches, enhancement of the solubilization by means of thermochemical pretreatment was investigated in this study at two temperatures (55°C and 131°C) and six sodium hydroxide (NaOH) concentrations (0, 1.25, 2.5, 5, 10 and 20g/L). The MBM volatile solid (VS) reduction ratio was up to 66% and 70% at 55°C and 131°C, respectively. At the same temperature, the VS reduction ratio increased with the increase in the dosage of NaOH. The study on the methane (CH) production potential of pretreated MBM shows that the addition of NaOH at 55°C did not cause the inhibition of the succeeding CH production process. However, CH production was inhibited by the addition of NaOH at 131°C. The CH production potential was in the range of 389 to 503mL CH/g VS MBM and 464 to 555mL CH/g VS MBM at 55°C and 131°C, respectively.

THE ROLE OF LONG-TERM EXPERIMENTS IN VALIDATING TRAIT-BASED APPROACHES TO ACHIEVING MULTIFUNCTIONALITY

《农业科学与工程前沿（英文）》 2022年第9卷第2期页码 187-196 doi: 10.15302/J-FASE-2021438

摘要：

Quantifying the relationships between plant functional traits and ecosystem services has been promoted as an approach to achieving multifunctional grassland systems that balance productivity with other regulating, supporting and cultural services. Establishing trade-offs and synergies between traits and services has largely relied on meta-analyses of studies from different systems and environments. This study demonstrated the value of focused studies of long-term experiments in grassland systems that measure traits and services in the same space and time to better understand the ecological constraints underlying these trade-offs and synergies. An analysis is presented that uses data from the Park Grass Experiment at Rothamsted Research on above-ground productivity, species richness and soil organic carbon stocks to quantify the relationships between these three outcomes and the power of variance in plant functional traits in explaining them. There was a trade-off between plots with high productivity, nitrogen inputs and soil organic carbon and plots with high species richness that was explained by a functional gradient of traits that are indicative of contrasting strategies of resource acquisition of resource conservation. Examples were identified of using functional traits to identify opportunities for mitigating these trade-offs and moving toward more multifunctional systems.

Huiqin HE, Thomas A. MONACO, Thomas A. JONES

《农业科学与工程前沿（英文）》 2018年第5卷第1期页码 139-147 doi: 10.15302/J-FASE-2017175

摘要： We conducted 30- and 60-d greenhouse experiments to compare functional traits of (invasive annual grass) and four perennial bunchgrasses under well-watered or drought conditions. Even under drought, experienced significantly less stress (i.e., higher xylem pressure potential and greater shoot water content, water use per day and water-use efficiency) and biomass production than the perennial grasses after 30 d. However, after 60 d, its superiority was reduced under infrequent watering. Differences among perennial grasses were more pronounced for physiological traits under infrequent watering and for morphological traits under frequent watering. (fast-growing species) had a higher transpiration rate, lower leaf temperature, and lower water-use efficiency than the other grasses after 30 d. In contrast, (slow-growing) had lower xylem pressure potential and higher leaf temperature than all other grasses under infrequent watering. Under frequent watering, shoot dry mass and specific leaf area of was matched by (moderate-growing species). Our results indicate that multiple-species plantings or seedings are necessary to foster greater weed resistance against . We also emphasize that when choosing plant material for restoration, performance during both pulse (resource-rich) and inter-pulse (resource-poor) periods should be considered.

《农业科学与工程前沿（英文）》 2014年第1卷第2期页码 91-95 doi: 10.15302/J-FASE-2014005

摘要： Backfat thickness is a good predictor of carcass lean content, an economically important trait, and a main breeding target in pig improvement. In this study, the candidate genes and genomic regions associated with the tenth rib backfat thickness trait were identified in two independent pig populations, using a genome-wide association study of porcine 60K SNP genotype data applying the compressed mixed linear model (CMLM) statistical method. For each population, 30 most significant single-nucleotide polymorphisms (SNPs) were selected and SNP annotation implemented using Build 10.2. In the first population, 25 significant SNPs were distributed on seven chromosomes, and SNPs on SSC1 and SSC7 showed great significance for fat deposition. The most significant SNP (ALGA0006623) was located on SSC1, upstream of the gene. In the second population, 27 significant SNPs were recognized by annotation, and 12 SNPs on SSC12 were related to fat deposition. Two haplotype blocks, M1GA0016251-MARC0075799 and ALGA0065251-MARC0014203-M1GA0016298-ALGA0065308, were detected in significant regions where the and genes were identified as contributing to fat metabolism. The results indicated that genetic mechanism regulating backfat thickness is complex, and that genome-wide associations can be affected by populations with different genetic backgrounds.

《工程（英文）》 2017年第3卷第5期页码 738-752 doi: 10.1016/J.ENG.2017.03.011

摘要：

活性氧（ROS）对人类和其他动物健康的负面影响非常值得关注。ROS可能由机械伤害、热刺激、感染和化学刺激产生。核转录相关因子（Nrf2）及其伴侣蛋白Keap1组成的Nrf2/Keap1系统在抗氧化作用中扮演着重要角色。Nrf2/Keap1系统通过与抗氧化反应元件（ARE）相互作用，调控一系列解毒酶和抗氧化酶基因的表达来维持机体氧化还原的平衡状态。膳食植物化学物质在蔬菜、水果、谷物和草药中普遍存在，研究发现其有益健康，还可通过多种途径调节Nrf2介导的II相酶来提高家畜的生长性能和肉质。然而，关于植物化学物质作用效果的大量数据有些混乱，需要根据植物化学物质的功能和作用机制进行相应的分类。在本文中，我们首先介绍了植物化学物质的抗氧化性及其与Nrf2/Keap1系统的关系，并总结了植物化学物质通过靶向Nrf2/Keap1系统，对家畜生长性能、肉质和肠道菌群的影响。这些详尽的数据有助于阐述植物化学物质在家畜中潜在的生物功能特性。

Caiyun LIU, Francisco PINTO, C. Mariano COSSANI, Sivakumar SUKUMARAN, Matthew P. REYNOLDS

《农业科学与工程前沿（英文）》 2019年第6卷第3期页码 296-308 doi: 10.15302/J-FASE-2019269

摘要：

The application of spectral reflectance indices (SRIs) as proxies to screen for yield potential (YP) and heat stress (HS) is emerging in crop breeding programs. Thus, a comparison of SRIs and their associations with grain yield (GY) under YP and HS conditions is important. In this study, we assessed the usefulness of 27 SRIs for indirect selection for agronomic traits by evaluating an elite spring wheat association mapping initiative (WAMI) population comprising 287 elite lines under YP and HS conditions. Genetic and phenotypic analysis identified 11 and 9 SRIs in different developmental stages as efficient indirect selection indices for yield in YP and HS conditions, respectively. We identified enhanced vegetation index (EVI) as the common SRI associated with GY under YP at booting, heading and late heading stages, whereas photochemical reflectance index (PRI) and normalized difference vegetation index (NDVI) were the common SRIs under booting and heading stages in HS. Genome-wide association study (GWAS) using 18704 single nucleotide polymorphisms (SNPs) from Illumina iSelect 90K identified 280 and 43 marker-trait associations for efficient SRIs at different developmental stages under YP and HS, respectively. Common genomic regions for multiple SRIs were identified in 14 regions in 9 chromosomes: 1B (60–62 cM), 3A (15, 85–90, 101–105 cM), 3B (132–134 cM), 4A (47–51 cM), 4B (71–75 cM), 5A (43–49, 56–60, 89–93 cM), 5B (124–125 cM), 6A (80–85 cM), and 6B (57–59, 71 cM). Among them, SNPs in chromosome 5A (89–93 cM) and 6A (80–85 cM) were co-located for yield and yield related traits. Overall, this study highlights the utility of SRIs as proxies for GY under YP and HS. High heritability estimates and identification of marker-trait associations indicate that SRIs are useful tools for understanding the genetic basis of agronomic and physiological traits.

From total quality management to Quality 4.0: A systematic literature review and future research agenda

《工程管理前沿（英文）》 doi: 10.1007/s42524-022-0243-z

摘要： Quality 4.0 is an emerging concept that has been increasingly appreciated because of the intensification of competition, continually changing customer requirements and technological evolution. It deals with aligning quality management practices with the emergent capabilities of Industry 4.0 to improve cost, time, and efficiency and increase product quality. This article aims to comprehensively review extant studies related to Quality 4.0 to uncover current research trends, distil key research topics, and identify areas for future research. Thus, 46 journal articles extracted from the Scopus database from 2017 to 2022 were collected and reviewed. A descriptive analysis was first performed according to the year-wise publication, sources of publication, and research methods. Then, the selected articles were analyzed and classified according to four research themes: Quality 4.0 concept, Quality 4.0 implementation, quality management in Quality 4.0, and Quality 4.0 model and application. By extracting the literature review findings, we identify the Quality 4.0 definitions and features, develop the quality curve theory, and highlight future research opportunities. This study supports practitioners, managers, and academicians in effectively recognizing and applying Quality 4.0 to enhance customer satisfaction, achieve innovation enterprise efficiency, and increase organizational competitiveness in the era of Industry 4.0.

摘要： This study was conducted to systematically assess the reproductive performance of transgenic ewes. In the transgenic founders (F ) and their positive offspring (F ), hematological and reproductive parameters and the global DNA methylation level in oocytes at various stages were analyzed. The values of the physiological and biochemical parameters determined from the blood samples did not differ significantly between the transgenic and wild-type ewes. Moreover, the transgenic ewes showed reproductive traits similar to the wild-type ewes. These traits included characteristics of puberty, the estrus cycle, estrus duration, gestation, the pregnancy rate and the superovulation response. Additionally, no significant differences were found between transgenic and wild-type ewes in the DNA methylation level of the oocytes at various stages. In summary, the preliminary evidence presented in this paper demonstrates that the presence of the transgene did not affect the reproductive performance in sheep.
