Observations on oestrus length and time of ovulation in zebu cattle



Observations on oestrus length and time of ovulation in zebu cattle



Observacoes sobre a duracao do estro e momento de ovulacao no gado zebu:



At Uberaba Experimental Station, length of oestrus of 38 milking zebu, 13 Indo-Brazilian and 19 Nellore cows averaged 17.5, 14.8 and 12.9 h resp., and ovulation occurred an average of 13.6, 13.7 and 13.8 h resp. following the end of oestrus. Parity had no significant effect on time of ovulation. Repeatability of oestrus length was 0.44 and that of length of the interval from the end of oestrus to ovulation was 0.02.
