Assessment of Sex Ratio in Mandya Sheep under Farm Condition
Journal Title: International Journal of Agricultural Sciences and Veterinary Medicine - Year 2015, Vol 5, Issue 2
Abstract
Data on 1505 lambing records were collected over a period of seven years from 2010 to 2016 for establishing the sex ration in Mandya sheep maintained at LRIC (S), Nagamangala, Mandya district, Karnataka state. The overall sex ratio was found to be 51.30% male lambs and 48.70% female lambs. The chi square value confirmed that the overall sex ratio in Mandya sheep is not significantly different from the hypothetical value of 50% males and 50% females. Season of birth, year of birth, month of birth, parity and ewe age had non significant effect on the sex ratio and confirmed that these non-genetic factors does not influence the sex ratio in Mandya sheep.
