Phenotypic morphometric parameters of indigenous pig of Nagaland

Abstract

The present study was conducted to measure the phenotypic morphometric parameters of Naga indigenous pig in Kohima, Peren and Phek district of Nagaland at birth, weaning and adult stage in both male and female animals. These parameters were collected through measurement and field survey. The morphometric parameters such as body weight (g or kg), body length (cm), heart girth (cm) and height at wither (cm). The result revealed that there was a significant difference between the male and female in different districts and in different age groups for all the morphometric parameters except body weight at weaning and heart girth at weaning and adult. Similarly, the significant difference was observed among the different districts of Nagaland for all the parameters except that of heart girth at birth and adult and body length at adult. The phenotypic parameters were significantly higher in male than in female animal in three stages. Similarly, body weight at birth and weaning stage was significantly higher in Phek district, body length at weaning and adult, heart girth at birth, body weight and height at wither at adult were significantly higher in Peren district and height at wither at birth and weaning, body length at birth and heart girth at weaning and adult were significantly higher in Kohima district. These phenotypic morphometric parameters analyses may be useful in selection of breeding stock for future parents and select the place for breeding programme of local indigenous Naga pigs.
