Oestrous cycles in Bos taurus cattle

The oestrous cycle in cattle lasts for 18-24 days. It consists of a luteal phase (14-18 days) and a follicular phase (4-6 days). During the cycle there are generally two (dairy cows) or three (heifers and beef cows) waves of ovarian follicle growth.

Carcass and meat quality of Bos indicus x Bos taurus and Bos taurus cattle in northern Australia

Australian Journal of Experimental Agriculture, 1989
Liveweights, carcass characteristics, bruising and muscle properties of Bos indicus x Bos taurus (BiX) and Bos taurus (Bt) cattle (1070 steers and 394 cows) were compared from 7 experiments throughout Queensland. In general, the cattle were weighed (unfasted), transported as mixed genotype groups to an abattoir and given access to water from arrival ...

Heterosis in Bos taurus × Bos indicus crosses

Livestock Production Science, 1985
Abstract Data extracted from reports on Bos taurus × Bos indicus crossbreeding were used to estimate the amount of heterosis in these crosses. Traits studied were age at first calving, milk yield, lactation length, and calving interval. The estimates obtained were (percent of midparent means in parentheses): Age at first calving −3.2 to −4.4 ...
