摘要

对牲畜胴体组成的评估产生有关肉制品质量和最终产量的相关信息。这项工作的目的是评估超声测量的腰最长肌体内与物理化学成分的相关性一岁圣伊内斯羊在广泛的系统中饲养。超声评估肋眼面积(USrea)、腰深(USld)、腰宽(USlw)和皮下脂肪厚度(USsft)。屠宰后,对肉块称重并计算胴体产量。将左侧的第12根肋骨从胴体中分离并解剖,然后分离单个骨骼,肌肉和脂肪并称重。这些组件被重新组合、研磨并收集起来进行百分位评估。超声测量值与肉质指标之间呈显著正相关(p < 0.05),除腰长呈低相关外。肌肉与USld、USrea和USsft测量值之间存在显著相关(p < 0.05)。骨密度与USld、USrea呈显著负相关(p < 0.05)。USsft与胴体产量呈显著相关(p < 0.05)。因此,与腰最长肌相关的超声测量可以构成一个有价值的工具,用于评估在广泛系统中创建的一岁Santa Inês羊的物理化学成分和胴体。

Estimated correlations of ultrasound carcass measurements and physical-chemical components of Santa Ines sheep meat
The evaluation of the carcass composition of livestock generates relevant information on the quality and final yield of the meat products. The objective of this work was to evaluate correlations the ultrasound measurements in vivo of the Longissimus lumborum with the physical-chemical components of one-year-old Santa Ines sheep bred in extensive systems. The ultrasound evaluation was performed of the rib eye area (USrea), loin depth (USld), loin width (USlw) and subcutaneous fat thickness (USsft). After slaughter, meat cuts were weighed and carcass yield was calculated. The 12th rib on the left side was separated from the carcass and dissected, after which individual bones, muscles and fat were separated and weighed. The components were regrouped, ground and collected for centesimal evaluation. Significant positive correlations (p < 0.05) were found between the ultrasound measurements and meat metrics, except for the loin length, which had low correlation. Significant correlations (p < 0.05) were found between muscles and the measurements of USld, USrea and USsft. The correlations (p < 0.05) between the bones and USld and USrea were negative and significant. USsft presented correlation (p < 0.05) with carcass yield. Thus, the ultrasound measurements associated with the Longissimus lumborum could constitute a valuable tool for evaluating the physical-chemical components and carcass of one-year-old Santa Inês sheep created in extensive systems.
