| Popis: | Postnatal development of the infundibular region of the oviduct in Kuttanad ducks was studied using 78 ducklings from dayold to 24 weeks of age. The material was collected from six birds in each group at fortnightly intervals. lnfundibulum was not differentiated until 10~h week of age, but by 12 weeks it entered into a rapid phase of differentiation and the infundibulum was divisible into funnel and neck regions. Kuttanad duck showed a relatively short infundibulum similar to that of chicken and turkey. From 12"~ week to 24"' week of age, the funnel and neck parameters of infundibulum showed highly significant positive correlation with age and weight and length of the oviduct. However, no significant correlation was noticed between infundibular parameters and the body weight during postnatal period. It was observed that during the egg-laying period the weight-wise and length-wise contribution of infundibulum was found to be more than that in the pre-laying period. |
