Deposition rule of yolk cholesterol in two different breeds of laying hens

P. K. Yang, Tian, Y. D., Sun, G. R., Jiang, R. R., Han, R. L., and Kang, X. T., Deposition rule of yolk cholesterol in two different breeds of laying hens, vol. 12, pp. 5786-5792, 2013.

The objective of this study was to investigate the deposition rule of yolk cholesterol in Lushi Green-shelled and Silky Fowl layers. A total of 90 layers of each breed were selected at an age of 15 to 51 weeks. Productive performance was recorded on a weekly basis, whereas yolk cholesterol was determined at 4-week intervals from 21 to 51 weeks of age. The average yolk cholesterol content of Silky Fowl layers during the laying period was higher than that of Lushi Green-shelled layers (58.16 and 49.67%, P > 0.05).
