유전 및 육종 : 산양의 생존율에 대한 유전적 및 비유전적 요인 = Breeding and Genetics : Effect of Genetic and Non - Genetic Factors Other Then Disease on Kid Survivability in Goat

다국어 초록 (Multilingual Abstract)

This experiment was conducted to investigate the genetic and non-genetic factors affecting kid survivability in goats from birth to 90 days of age. The purebreds had lower survivability than the crossbreds, with significant (p<0.05) difference amongst themselvess for the age of 31 to 90 days. The locational effect on survivability was insignificant for all the periods except 16 to 60 days (p<0.05) of age. The sex and birth type also had significant (p<0.05) effect on survivability for all the periods except 0 to 7 days of age. The survivability was found to be significantly (p<0.05) higher for kids born in summer season followed by those born in winter and rainy season. Milk produced by the does were significantly (p<0.05) affected on the survivability of kids during the period from 16 to 60 days of age. The survivability of kids were highest and lowest having milk yield of doe found to be 400∼600 g/day and 80∼200 g/day, respectively. Birth weight had significant (p<0.05) effect on survivability for all the stages of growth up to 90 days of age. Survivability was positively correlated with does` milk yield as well as kids birth weight. Interactions of sex with location or birth type were significant (p<0.01 and p<0.05, respectively) though interaction between sex and genetic group was insignificant.
