Abstract

This study aimed to evaluate the correlations between mineral profile, physical and chemical characteristics, and proximate composition of ewe meat receiving different water supply levels (100% - ad libitum group; 80%; 60% and 40% ad libitum group). Thirty-two Santa Ines ewes were assigned to a randomized block design, with 4 treatments, and 8 replications, during the 63-day experimental period. Significant correlations between all minerals (P<0.05) were found in the 60% and 40% water supply levels. A correlation (P<0.05) was observed for minerals P, K, Ca, Mg, S, Cu, and Fe with crude protein at 100% water supply. Negative correlations (P<0.05) between N, P, K, Ca, Mg, S, Cu, Fe, and Zn were detected in the meat of animals supplied with 60% water. Principal component analysis (PCA) of macrominerals explained 82.9% data variance. Zinc had a strong contribution to PC1. Cooking losses had a similar contribution to PC1 and PC2. PC1 and PC2 explained 66.7% data variance in chemical characteristics. The decrease in water supply causes the correlation of nitrogen with the other minerals in meat, in addition to altering the correlation between the physical and chemical profile of the meat.

水分限制条件下Santa Ines母羊肉的矿物特征、物理化学特性和接近成分之间的相关性

本研究旨在评估接受不同供水水平（100%-随意组；80%；60%和40%随意组）的母羊肉的矿物特征、理化特性和接近成分之间的相关性。在63天的实验期内，32只Santa Ines母羊被分配到一个随机区组设计中，共有4次处理和8次复制。在60%和40%的供水水平下，所有矿物质之间存在显著相关性（P<0.05）。在100%供水条件下，矿物质P、K、Ca、Mg、S、Cu和Fe与粗蛋白质之间存在相关性（P<0.05）。在添加60%水的动物肉中，N、P、K、Ca、Mg、S、Cu、Fe和Zn呈负相关（P<0.05）。常量矿物的主成分分析（PCA）解释了82.9%的数据方差。锌对PC1有很强的贡献。烹饪损失对PC1和PC2的贡献相似。PC1和PC2解释了66.7%的化学特征数据差异。供水量的减少除了改变肉的物理和化学特性之间的相关性外，还导致氮与肉中其他矿物质的相关性。
