M Narayana Swamy and T. Veena | Sowmya Narayan
The present study was designed with the objective of understanding the ovarian antral follicular dynamics in Ankamali pigs, an indigenous south Indian breed of pig, that derives its name from Ankamali block in the Ernakulam district of Kerala, also found in Karnataka, Tamil Nadu, parts of Maharashtra and Andhra Pradesh. For the present study, the ovaries were collected from apparently healthy, non pregnant, cyclic and middle aged (2 to 5 years) Ankamali pigs slaughtered at civil meat processing and production centre, Frazer town, Bangalore during the month of February to May 2010. The February month was transition month from winter to summer and the month of March, April and May were considered as summer months. A total of 640 ovaries were collected and the surface antral follicles on the ovaries were classified into Group I (small, <3 mm), Group II (medium, 3-6.9 mm) and Group III follicles (large, 7-12 mm) on the basis of their diameter. The results of the present study revealed that the number of Group I follicles were significantly (P<0.05) higher compared to Group II and Group III follicles. Similarly, Group II follicles were significantly (P<0.05) higher compared to Group III follicles during different months of observation. An attempt was also made in the present study to find out the approximate ratio between the small, medium and large follicles wherein it was 7: 4:1 during the month of February and March and it was 6: 5: 1 during the month of April and May. The ovarian follicular dynamics established in the present study during winter to summer transition month like February and during summer months like March, April and May shall throw some insights into the ovarian physiology in Ankamali breed of pig.
