In a series of experiments, broiler-type New Hampshire, White Rock and Vantress x New Hampshire eggs from a commercial hatchery were held at temperatures ranging from 50掳 to 90掳 F. and were set at from 4 to 10 days old. In all experiments best hatchability was. obtained by holding egg...
The hatchability, embryonic development of eggs and growth of yolk sac fry were studied under controlled conditions. It was shown that the upper lethal temperature for O. mossambicus eggs was above 40°C and the lower lethal temperature between 11°C and IVC. For yolk sac fry these values ...
Then has taken two eggs from the refrigerator.“Hatches chicken's egg is depends on the big hen's body temperature to hatch, if I hatch, the egg is very easy to crush.Right, usually mother frequently said daddy's body on the stove, daddy's quilt definitely is likely hot.” I was th...

Therefore, the current investigation was conducted to determine the earliest day of incubation on which temperature transponder implantation in the egg air cell could be performed with minimal invasiveness to broiler embryogenesis. Eggs from young broiler breeder hens (Ross 308; 27 wk of age) were ...
variables. Physiological trade-offs also acted on the other end of the temperature gradient limiting the extent to which development can be delayed. Eggs of Chestnut-crested yuhina (Yuhina everetti) that were transferred to the colder temperature conditions of stubtail nests extended their embryonic...
compatible with a deletion encompassing a large part of theMLPHgene, the entirePRLHgene and a large part of theRAB17gene, according to the chicken genome annotation. Additional PCR tests confirmed that a deletion was likely to be associated withlavenderin Japanese quail, and allowed us to ...
; the remainder were stored at 55° P. for 4 days and acted as controls. All eggs were incubated in the same forced-draught incubator and those failing to hatch were broken and examined macroscopically for age at death. The hatchability of eggs from all breed...关键词:...
