Abstract: The aims of this experiment was to study the effects of Clostridium butyricum and sodium butyrate on egg production rate,freckles,dark spots and egg quality of laying hens in different breeds.320 270-day-old Langshan chickens,Barred Plymouth Rock or Beijing You chickens were randomly divided into 2 groups with 8 repeats in each group and 20 chickens in each repeat.The control groups(CON) were fed with basic diet and the experimental groups (EXP) were fed with diet added Clostridium butyricum (100 mg/kg) and sodium butyrate (500 mg/kg).The pre-feeding period was 3 days and the period of the experiment was 5 weeks.The results showed that:Compared with the control group,①The egg production rate of Langshan chicken,Barred Plymouth Rock and Beijing You chicken were increased by 12.5%,12.0% and 24.9% respectively (P<0.01).②The grade 3 rate of the freckles of the Langshan was decreased by 34.2% in the experimental group (P<0.05),there was no significant difference of dark spot rate of Langshan chicken,and no significant difference of freckle rates and dark spot rate in Barred Plymouth Rock and Beijing You chicken (P>0.05).③The egg weight was decreased by 1.7% (P<0.05),the egg shape index increased by 2.3% (P<0.05) of Langshan chicken in experimental group.The weight of the eggs of Barred Plymouth Rock increased by 1.5% (P<0.05).The protein height increased by 13.9% (P<0.05),and the Hastelloy unit increased by 4.7% (P<0.05) of Beijing You chicken in experimental group.In summary,adding Clostridium butyricum and sodium butyrate to the basic diets could increase the egg production rate of Langshan chicken,Barred Plymouth Rock and Beijing You chicken.It also had a certain effect on improving the freckles of Langshan chicken eggs,and could help to improve the egg quality of Barred Plymouth Rock and Beijing You chicken.
