Inheritance of teat number and relationship of teat number to various maternal traits in swine



Inheritance of teat number and relationship of teat number to various maternal traits in swine



Jour Animal Sci 20(4): 876-879



The estimates of heritability of total teat number obtained in a population of Minnesota No. 1 swine were 0.10 [plus or minus] 0.04 from the dam-offspring regression analysis and 0.23 [plus or minus] 0.20 from the paternal half-sib correlation. The regressions of various maternal traits on total teat number were small and statistically non-significant for the traits considered Significant regression values of 0.27 and 1170 were found for the regression of number of pigs weaned and pounds of pigs weaned on functional teat number after removing the effect of number of pigs born alive.
