The organic-rich shale of the Member 1 of the Keluke Formation (in this paper referred to as Member 1) has been newly discovered as a good source rock reservoir in the western Delingha Depression, Huaitoutala area in the east part of the northern margin of Qaidam Basin, but the factors that control the enrichment of the organic matter in the shale are still unclear. In this paper, the paleo-climate, redox condition, paleo-salinity, hydrothermal activity and primary productivity of the dark shale in Member 1 are studied based on the analysis results of the total organic carbon (TOC), the element geochemistry and the whole rock mineral testing, and the enrichment mechanism of organic matter is discussed. Based on the vertical variation of the TOC contents, the Member 1 shale section is divided into two sub-sections (Sub-section I and Sub-section II), with the TOC content of Sub-section II (avg.

The aim of this study is to investigate the physiological characteristics and regulatory mechanisms of porcine intramuscular fat (IMF), subcutaneous fat (take back fat (BF), for example), and visceral fat (take perienteric fat (PF), for example) to address the challenge of optimizing meat quality without excessive fat deposition. Many improved breed pigs have fast growth rates, high lean meat rates, and low subcutaneous fat deposits, but they also have low IMF content, resulting in poor meat quality. There is usually a positive correlation between intramuscular fat and subcutaneous fat deposits.

: Fat deposition traits in pigs directly influence pork flavor, tenderness, and juiciness and are closely linked to overall pork quality. The Tibetan pig, an indigenous breed in China, not only possesses a high intramuscular fat content but also exhibits a unique fat metabolism pattern due to long-term adaptation to harsh environments. This makes it an excellent genetic and physiological model for investigating fat deposition characteristics.

Mesometrium is the "gateway" through which the endometrium exchanges nutrients and substances with the outside world due to blood vessels entering endometrium across mesometrium. Therefore, dissecting the transcription atlas of the mesometrium will be a great help in understanding the role of mesometrium during implantation. In this study, we collected samples from the mesometrium and adjacent endometrium on the 12 day of estrous cycle and pregnancy.

A novel method is proposed based on the improved YOLOV5 and feeding functional area proposals to identify the feeding behaviors of nursery piglets in a complex light and different posture environment. The method consists of three steps: first, the corner coordinates of the feeding functional area were set up by using the shape characteristics of the trough proposals and the ratio of the corner point to the image width and height to separate the irregular feeding area; second, a transformer module model was introduced based on YOLOV5 for highly accurate head detection; and third, the feeding behavior was recognized and counted by calculating the proportion of the head in the located feeding area. The pig head dataset was constructed, including 5040 training sets with 54,670 piglet head boxes, and 1200 test sets, and 25,330 piglet head boxes.
