The composition of egg yolk absorbed by fasted ostrich (Struthio camelus L.) chicks from 1 to 7 days posthatching and for ostrich (Struthio camelus L.) chicks from 1 to 16 days posthatching on a prestarter broiler diet

Yolk sac utilization in ostrich (Struthio camelus) chicks.

The mass of residual yolk sac expressed as a percentage of initial mass of the egg from which the chick hatched decreased sharply in the first 2 days post-hatching. A gradual reduction occurred between 3 and 10 days after which a sharp decline was noted between 11 and 13 days post-hatching. The highest number of chicks with unabsorbed yolk sac was noted on day 5 post-hatching followed by days 6...

Proventricular-Ventricular Impaction in Ostrich (Struthio Camelus)

In this study from 58 of 4 month male and female ostrich with 3 pieces of dead ostrich during 24 hours and 8 ostrich with dangerous general conditions history of manufactured flock have gotten after prime survey about farm condition, lack of enough space, unsuitable availability to drinkers and feeders and most important, lack of suitable litter for breeding and increase of stress to birds were...

Declawing ostrich (Struthio camelus domesticus) chicks to minimize skin damage during rearing

Leather is one of the main products derived from ostrich farming. Current rearing practices lead to a high incidence of skin damage, which decreases the value of ostrich skins. In the emu and poultry industry, declawing is commonly practiced to reduce skin damage and injuries. We consequently investigated declawing of ostrich chicks as a potential management practice to minimize skin lesions th...

Road transportation effect on rectal temperature, respiration and heart rates of ostrich (Struthio camelus) chicks

The responses of rectal temperature (RT), respiratory rate (RR) and heart rate (HR) of ostrich (struthio camelus) chicks during road transportation were investigated using standard recording procedures. The RT and RR of the ostriches increased significantly (P<0.05) from 39.5 ± 0.1 0C and 12.2 ± 2.0 breaths per minute (bpm), respectively, before transportation, to 40.2 ± 0.3 0C and 50.7 ± 9.1 b...
