Abstract:

The present study was designed to analyse the factors influencing fatty liver weight.Taking the overfeeding results in 2014 and the local temperature together,effects of gender,temperature and body weight on fatty liver weight were studied and the results would provide reference information for improving fatty liver production and breeding work.Totally 415 geese at 10 weeks old were overfed for 28 days.Body weight before and after overfeeding,fatty liver weights,abdominal adipose weights were measured.Blood samples of geese were collected for DNA extraction to determine the gender.The results showed that body weight before and after overfeeding and gain weight during overfeeding period were all associated with liver weight extremely significantly and the correlation coefficient were 0.40,0.62 and 0.46,respectively (P < 0.01).The body weight after overfeeding showed extremely significant effect on fatty liver weight (P < 0.01).Gender showed no significant effect on liver weight when the body weight were similar between female and male geese (P > 0.05).Effect of temperature on liver weight was extremely significant (P < 0.01).Overfeeding work should be conducted between 13.6 to 25.2 ℃ and the optimal temperature was 20.3 ℃.Higher temperature would result in reduction of fatty liver weight.In summary,temperature was a fundamental guarantee for fatty liver production and body weight was an indirect selecting index when cultivate a breed specific for fatty liver.Further,gender showed no significant effects on fatty liver weight.

Key words: fatty liver production; body weight; gender; temperature
