Abstract:

A study to determine the growth pattern and development of digestive organs of male and female quails was conducted using a total of 420 day-old Japanese Seattle quails. The birds were weighed weekly for growth monitoring. Two birds were sacrificed from each of the 6 replicates every 3 days from day 1 to day 79.

Results showed that female quails were heavier (P<0.01) than males starting day 35 and onward. The relative growth of the gastrointestinal tract (GIT) was highest during the first week of growth and females had heavier (P<0.01) GIT than that of males starting day 46. The proventriculi of females were also heavier than that of males at day 67 while gizzard did not vary between the 2 sexes. The liver and the Intestines grew rapidly during the first 2 weeks of age. These two digestive organs contributed much to the heavy weights of the GIT In females.
