Exploration of development characteristics of abdominal adipose tissue in Lindian chickens
In the production of broiler chickens,excessive deposition of abdominal fat can lead to series of problems such as decreased production efficiency.As one of the high-quality native chicken breeds,Lindian chickens due to excellent egg and meat production performance,delicious meat are deeply popular by the public.To explore the developmental characteristics of abdominal fat tissue of Lindian chickens,the body weight and abdominal fat weight of Lindian chickens at 3-22 weeks were measured,the size and quantity of abdominal adipocytes were observed and counted,and the relationship between adipocyte characteristics and abdominal fat deposition was analyzed in present study.The results showed that the weight of Lindian chickens continued to increase from 3 to 22 weeks,and the abdominal fat weight first increased,then decreased,and strengthened again.The abdominal fat percentage first decreased and then increased.At 3-10 weeks,adipocytes were proliferatted,while at 10-14 weeks,adipocyte enlargement dominated.After 19 weeks,both adipocyte enlargement and proliferation occurred simultaneously,but mainly enlargement.In addition,a regression model between abdominal fat weight and adipocyte characteristics was preliminarily determined in this study,and it was found that adipocyte volume had the better impact on abdominal fat weight.These results would provide theoretical references for the breeding of high-quality and distinctive new strains of Lindian chicken.
