Chicken eggs are relatively tolerant compared to some waterfowl eggs, but if you are struggling with hatchability, then you might want to try the weight loss method. Egg weight loss With the correct humidity,eggs need to lose 13 to 14% of their weight*.This needs to be over the entire ...
Changshun green-shell laying hen is a notable indigenous chicken breed in Guizhou province, China, and has strong broodiness. It is well known for its more nutritious green-shell eggs with better amino acid composition, higher contents of protein and lower fat and cholesterol content. Recently, ...
Fresh eggs were artificially collected from nest boxes and storaged at the following environmental conditions no more than 7 days: room temperature of 15°C–18°C, relative humidity of 70–75%. These eggs were numbered and weighted individually at the range of 84.0 ± 2.0g and divided into...
This study evaluated the subsequent effect of photoperiods during incubation on post-hatch growth and stress response of commercial broiler chickens. A total of 875 Ross 308 broiler breeder (48 weeks of age) eggs were hatched using different durations (0, 4, 8, 12, 16, 20, and 24 h a ...
However, previous research of photostimulation during incubation has mainly focused on rapidly growing broilers or high-yield laying hens, and only a few have assessed geese. Hatchability is considerably lower for fertile goose, than chicken eggs. Low hatchability is attributed in part to poorly ...
