Morphometerical observations of intestine in Japanese quail

Abstract

The present study was conducted on duodenum, jejunum, ileum, caecum and colorectum of Japanease quail. The weight of the duodenum on day 7th and 42nd was 0.47±0.05 g and 1.45±0.09 g, respectively. The length of the duodenum was found to be 8.60±0.36 cm and 14.13±0.55 cm on the same observation days. The weight and length of the jejunum ranged from 0.47±0.07 g to 1.62±0.19 g and 11.99±0.33 cm to 23.70±1.10 cm on day 7th and 42nd old birds, respectively. The values for the weight and length of the ileum were 0.30±0.03 g to 1.32±0.12 g and 10.21±0.80 cm to 20.88±1.61 cm, respectively at 7th and 42nd old birds of age. The weight and length of caecum were ranged from 0.22±0.03 g to 1.13±0.18 g and 4.13±0.07 cm to 7.69±0.30 cm. The values for the weight and length of the colorectum were 0.10±0.01 g to 0.51±0.05 g and 3.36±0.16 cm to 6.93±0.33 cm. The total length and weight of the five constituents, i.e. duodenum, jejunum, ileum, caecum and colorectum together formed the entire weight and length of the intestine which ranged from 1.55±0.08 g to 6.02±0.43 g and 37.97±1.04 to 73.34±1.61 cm, respectively at 7th and 42nd old birds of age.
