DAI Z H,LI T P,ZHAO X Y.Breeding and management technology of "Duwu Golden Phoenix" laying hens (Ⅱ). Key words: dietary CP level Dawu Golden Phoenix commercial laying hens peak egg production production performance egg quality The eyes are dark reddish brown, The toes are light to dark blue.In this study,the effects of dietary crude protein (CP) level on the production performance and egg quality of Dawu Golden Phoenix commercial layer were studied to determine the CP requirement.In the experiment,480 31-week-old Dawu Golden Phoenix commercial layers were selected and randomly divided into 4 treatment groups with 12 replicates in each group and 10 layers in each replicate.The CP levels of the 4 treatment groups were 13.5%,14.5%,15.5% and 16.5%,respectively.The pre-test period was 7 d,and the formal period was 63 d.During the experiment,the number of eggs laid by layers,egg weight and unqualified eggs were recorded every day.Feed intake was counted by repetition every 2 weeks,and average daily feed intake (ADFI) and feed-to-egg ratio (F/E) were calculated.At week 6 of the experiment,three eggs were taken for each iteration to determine egg quality.The results showed that:① The CP level in the diet had a significant impact on the daily egg production,average daily feed intake and feed-to-egg ration of laying hens ( P<0.05).The average daily feed intake and the daily egg production of laying hens in 16.5% CP group was significantly higher than that in 13.5% and 14.5% CP groups ( P<0.05),and the daily egg production increased linearly with the increase of the CP level in the diet ( P<0.05).The feed-to-egg ratio in 16.5% CP group was significantly lower than that in 13.5%,14.5% and 15.5% CP groups ( P<0.05).②Dietary crude protein level had a significant effect on the proportion of egg shell and yolk color ( P<0.05).The proportion of egg shell in the 13.5% CP group was significantly higher than that in the 16.5% CP group ( P<0.05),and the proportion of egg shell decreased linearly with the increase of the dietary CP level ( P<0.05).The yolk color in 13.5% CP group was significantly higher than that in 16.5% CP group ( P<0.05),and the yolk color decreased linearly with the increase of diet CP level ( P<0.05).By establishing the regression curve between feed-to-egg ratio and protein level (y=275x 2-86.4x+8.7356),the protein level for the minimum feed-to-egg ratio was 15.7%.Therefore,considering the results of production performance and egg quality,the dietary crude protein level of Dawu Golden Phoenix commercial layer during peak egg production period was recommended to be 15.7%. The special qualities of the Phoenix breed are that the chickens are typically small, ornamental birds, with long tails. White egg What is a phoenix chicken look like? ![]() The egg will emit flame particles when the light level is right. They require a light level of at least 9 to hatch. Phoenix eggs can be placed by right clicking the ground. How do you hatch a phoenix egg in Minecraft? Like all other birds, the phoenix reproduce by laying eggs. Phoenix Chicken Eggs They are often reported to lay around three white, creamy, or light brown eggs a week, although some sources put the number as low as one! As if that wasn’t bad enough, Phoenix chicken eggs are small. Also, they should be turned at least 3 times per day. It takes about 21 days for them to hatch. White How long does it take for a phoenix egg to hatch? Phoenix chicken How many eggs does a Phoenix chicken lay? The size for a Phoenix breeds Standard Male is 5.5 pounds and a Standard Female is 4 pounds. A Bantam is a chicken of a smaller breed, the male of which is noted for aggression. ![]() The Phoenix breed is a Standard Class: English / Bantam, Single Comb, Clean Legged chicken. Phoenix chickens are recognized by the American Poultry Association as a standard breed in three varieties: Silver (1965) and Golden (1983) Black Breasted Red (approximately 2003). ![]()
