Comparative Analysis of Serum Mineral and Biochemical Parameter Profiles Between Late Pregnant and Early Lactating Jennies.

This research article compares the serum mineral, biochemical, and hematological profiles of Chinese Liaoxi jennies (a breed of donkey) during their late pregnancy and early lactation stages. It identifies significant variances between the two phases, providing useful insights into their physiological status and potential health care needs.

Research Methodology

• Twenty-five healthy Chinese Liaoxi jennies were studied during two critical stages: late pregnancy and early lactation.
• The elements and parameters scrutinized included serum trace and major elements, and biochemical and hematological aspects.
• Principal component analysis and cluster analysis methodologies were both employed to collate and interpret the data. These methods help to identify patterns and groupings within the collected data.

Key Findings

• The research identified notable interindividual variations in serum levels of Fe, TP, and AST among the jennies.
• During the early lactation stage, the jennies demonstrated significantly lower serum levels of K, Se, AST, TC, and triglycerides compared to their late pregnancy stage.
• Six principle components were identified in the late pregnancy phase, while five were observed during early lactation.
• The study found specific mineral and biochemical clusters – groups with close association – in the two stages. In late pregnancy, strong clusters of serum elements included Cu-Mn, iPhos-Se-TP, and Ca-Zn-alanine aminotransferase-TC, whereas in early lactation Ca-Zn-Se-Mn-albumin, Na-Fe-AST-triglyceride, and K-Mg-Cu-TP were the observed groupings.

Implications of the Study

• This research offers invaluable information about considerable variations in the serum levels of various mineral and biochemical parameters in late pregnant and early lactating jennies.
• Such insights hold significant potential for helping to appraise the physiological condition of these animals more accurately during these important life stages and can provide better guidance for providing appropriate health care.
