| Summary: | 10 hybrid ISA Brown hens, 50 weeks old, hold single in cages and fed with
combined granulated forage, were monitored for a period of 3 weeks. They were
divided into 4 groups depending on the stages of the egg formation. When 53 weeks
old, the the blood samples were prevailed and thereafter prepared to determine the
haematological parameters and the calcemia and phosphoremia..
The values of haematological parameters (the eritrocytes sedimentation rate, the
haemoglobine content, the haematocrit and the leukocitar formula) are within the
normal limits and that no variations appear depending on the egg position in the
oviduct.
The calcemia values are within the normal limits (20-35 mg%) for hens during their
laying period, The mean value is 34.19±0.96 mg %. The statistical processing of the
data does not reveal significant differences (p>0.05) among the calcemia values,
irrespective of the egg formation stage.
The phosphoremia values show significant modifications during the 24-25 hours
necessary for the egg formation: at 30 minutes postoviposition the mean value of
the phosphoremia represented 4.86±0.14 mg%, and at 22-23 hours postoviposition
the level of the blood phosphorous represented 4.64±0.10 mg%, while at 10-12
hours postoviposition the registered mean value was 6.79±0.07 mg% phosphrous. |
