THE EFFECT OF MILK FEED SUPPLEMENTATION ON EGG PRODUCTION AND EGG QUALITY OF DOMINANT LAYING HENS FROM 53 TO 66 WEEKS OF AGE RAISED IN THAI NGUYEN

Abstract

The objective of this study was to determine the effect of Milk feed supplementation on egg production and egg quality of Dominant laying hens from 53 to 66 weeks of age. The study was designed into two groups including the control group (no supplementation Milk feed) and the treatment group (supplementation 0.4% Milk feed). Each group had 85 birds, replication 3 times with 6 experimental units. The results showed that the egg-laying rate, egg production and egg weight in the control and treatment groups were 70.50 % and 73.25%; 4.94 eggs/hen/week and 5.13 eggs/hen/week; 60.95 g/egg and 61.37 g/egg, respectively. There were no significant differences on egg quality parameters between the control and treatment groups. At the age of 62 weeks, the yolk color of eggs in the control and treatment groups were 11.2 and 12.4. Feed conversion rate for 10 eggs in the control and treatment were 1.56 kg and 1.52 kg, respectively. Therefore, Milk feed supplementation with level of 0.4% to the feed of Dominant laying hens from 53 to 66 weeks of age increased their survival rate, and improved remarkably egg-laying rate, egg production and egg weight.
