Biochemical changes associated with fatty liver in geese

Area of Science:

• * Biochemistry
• * Animal Science
• * Genetics

Background:

• * Understanding the biochemical alterations in geese liver during the cramming period is crucial for optimizing production.
• * Previous research has not fully elucidated the specific enzymatic and lipid changes associated with liver fattening in geese.

Purpose of the Study:

• * To investigate biochemical changes in goose blood and liver during cramming.
• * To identify potential biochemical markers for liver fattening and genetic differentiation in geese.
• * To assess the impact of transportation on blood constituents.

Main Methods:

• * Analysis of liver enzymes (MDH, LDH, AST, ME, ALP, ICDH, G6PDH) and serum constituents (enzymes, total lipids, albumin, hematocrit, glucose, proteins, phosphorus).
• * Correlation analysis between liver size and biochemical parameters.
• * Comparison of biochemical profiles between gray and white goose families.

Main Results:

• * Significant increases in liver enzymes (MDH, LDH, AST, ME) and serum parameters (ME, ICDH, LDH, MDH, AST, ACP, SDH, total lipids) were observed.
• * Decreases in alkaline phosphatase (ALP), serum albumin, and hematocrit were noted.
• * Good correlations were found between liver size and certain biochemical parameters, suggesting their utility as markers for liver fattening.

Conclusions:

• * Specific biochemical parameters in blood and liver can indicate the presence and extent of liver fattening in geese.
• * Observed differences between goose families suggest the potential use of these parameters as genetic markers.
• * Transportation stress affects blood constituent levels, requiring consideration in analyses.
