Basic Information
Scope
Scope: This document specifies the terminology and definitions for the segmentation of yak stomachs (bellies), raw materials and workshop requirements, segmentation techniques, transportation, storage, logistics, and quality and waste management requirements. This document is applicable to yak slaughter and processing enterprises. Main technical content: Based on the different muscle layer thicknesses of each yak stomach, the rumen, reticulum, omasum, and abomasum are extracted. First, the rumen is divided into belly-leading and non-belly-leading parts, and lymph nodes, connective tissues, and excess fat are removed. The yak stomachs (bellies) are then standardized for segmentation. 1. Segmentation of yak stomachs: The rumen, reticulum, omasum, and abomasum are extracted. First, the rumen is divided into belly-leading and non-belly-leading parts, and the muscle layer thickness of the non-belly-leading parts and the reticulum, omasum, and abomasum are measured using a vernier caliper. 2. Segmentation method of the rumen: - Belly-leading: Segmented along the belly-leading and other parts of the yak rumen. - Non-belly-leading: Segmented according to the muscle layer thickness of less than 0.5 cm. - Reticulum, omasum, and abomasum: Segmented according to the muscle layer thickness of 0.5 cm to 1.0 cm. - Excess fat: Segmented according to the muscle layer thickness of more than 1.0 cm. 3. Segmentation method of the abomasum: - Abomasum: Segmented according to the muscle layer thickness of less than 0.5 cm. - Omega: Segmented according to the muscle layer thickness of 0.5 cm to 1.0 cm. - Reticulum: Segmented according to the muscle layer thickness of less than 0.5 cm. 4. Segmentation method of the omasum: - Omasum: Segmented according to the muscle layer thickness of less than 0.5 cm. - Reticulum: Segmented according to the muscle layer thickness of 0.5 cm to 1.0 cm. 5. Segmentation method of the reticulum: -
