中文摘要:选择7只50日龄、屠体质量在1.741~2.508kg之间的三黄鸡为试验对象,测量其体尺参数、全净膛质量、主要内脏器官质量及内脏总质量,分析这些参数随屠体质量的变化关系。利用螺旋CT机采集样本的CT断层扫描图像,根据样本的横纵切面图像,分别分析确定心脏、肺脏、肌胃和肾脏等主要脏器的相对位置,并估算出内脏腔体的尺寸及净膛切口的位置和尺寸。试验结果显示,随着三黄鸡胴体屠体质量的增加,胸深和胫长逐步增大,而体斜长、胸宽和胫围则显著的线性增加(P<0.01)。心脏、肺脏、肌胃和肾脏的质量也随屠体质量的增加而呈增大趋势,且具有一定的相关性。另外,根据胴体的横纵CT图像,可以清楚地确定心脏、肺脏、肌胃和肾脏的相对位置;对屠体质量分布为1.741~2.508kg的三黄鸡样本,估算出腔体尺寸为:内脏腔体长度(15.560±0.540)cm,最大宽度(7.722±0.253)cm,最大净膛开口尺寸(4.783±0.467)cm。

Abstract:Seven Sanhuang chicken carcasses, which were 50d old and the carcasses weight was in the range of 1.741~2.508kg, were selected as experimental samples. Their body size parameters, eviscerated weight, main organs weight and viscera weight were measured and then the relationships of these parameters with the carcass weight were analyzed and investigated. After the sample’s cross sectional images were captured by using a spiral CT machine, the relative positions of heart, lung, stomach, kidney and other major viscera were observed and in the same time, the visceral cavity size and the position and size of the eviscerated incision were estimated according to these images. Experiment results showed that their breast depth and shank length were gradually increased with the raise of carcass weight of Sanhuang chicken. Furthermore, the body length, breast width and shank circumference were significantly increased (P<0.01) linearly as the carcass weight was increased. The weight of heart, lung, stomach muscle and kidney also showed a trend of increase with the rise in carcass weight, which had certain relevance. In addition, the relative position of the heart, lung, muscle stomach and kidney could be clearly determined based on the horizontal and vertical cross sectional CT images of carcass;for the Sanhuang chicken samples with carcass weight distribution of 1.741~2.508kg. The estimated cavity size was (15.560±0.540)cm long, (7.22±0.253)cm wide, and the maximum incision length was (4.783±0.467)cm.

Transactions of the Chinese Society for Agriculture Machinery (CSAM), in charged of China Association for Science and Technology (CAST), sponsored by CSAM and Chinese Academy of Agricultural Mechanization Science(CAAMS), started publication in 1957. It is the earliest interdisciplinary journal in Chinese which combines agricultural and engineering. It always closely grasps the development direction of agriculture engineering disciplines and the published papers represent the highest academic level of agriculture engineering in China. Currently, nearly 8,000 papers have been already published. There are around 3,000 papers contributed to the journal each year, but only around 600 of them will be accepted. Transactions of CSAM focuses on a wide range of agricultural machinery, irrigation, electronics, robotics, agro-products engineering, biological energy, agricultural structures and environment and more. Subjects in Transactions of the CSAM have been embodied by many internationally well-known index systems, such as: EI Compendex, CA, CSA, etc.
