Correlations between blood polymorphic systems and fertility in Italian Friesian cows



Correlations between blood polymorphic systems and fertility in Italian Friesian cows



Rivista di Zootecnia e Veterinaria 8(6): 430-435



During 1969-73, data were collected on infertility in a herd of 2067 cows. The cows were classified as normal or were put into 4 subfertile grades. The cows were also typed for the A, B, C, F/V, J, L, M, Su, Z and R'/S' blood group systems, and for biochemical polymorphism at the Al, Tf, Am, Ca and Hb loci.
