223 PREANTRAL FOLLICLES POPULATION IN BOS TAURUS INDICUS AND BOS TAURUS TAURUS FEMALES
Reproduction, Fertility and Development, 2009Bos taurus indicus females provide a greater in vivo oocyte recovery (2-4 times more) in comparision with Bos taurus taurus. This aspect has strongly contributed for the success of the embryo industry in Brazil. Little information is available to explain this difference.

Animal Reproduction Science, 2009
In vitro studies have shown that Bos taurus indicus (B. t. indicus) embryos submitted to heat shock at early stages of development are better able to survive as compared to Bos taurus taurus embryos. Embryo genotype influences resistance to heat shock thus leading to the question as to whether embryos sired by thermo-tolerant breeds exhibit the same ...

Composition and Yield of Milk from Beef-Type Bos Taurus and Bos Indicus × Bos Taurus Dams
Journal of Animal Science, 1987Yield, butterfat, protein, lactose and solids-not-fat of milk from mature dams (n = 128) representing eight Bos taurus and Bos indicus X Bos taurus breed types were evaluated approximately 60, 105 and 150 d postpartum. Breed type was a significant source of variation in milk yield at each stage of lactation. Average 24-h milk yields (kg) were: Hereford,

Neoplasms in Calves (Bos taurus)
Veterinary Pathology, 1982From January 1, 1977 through December 31, 1978, 529,077 calves were slaughtered at a Wisconsin abattoir. Tissues from 36 calves found unfit for human consumption because of suspected neoplasia were examined histologically, and 19 lymphomas, seven mesotheliomas, one embryonal nephroma, one fibroma and one hemangiosarcoma were found.

Oestrous cycles in Bos taurus cattle
Animal Reproduction Science, 2011The 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. Each wave of follicle growth consists of a period of emergence of a cohort of follicles, selection of a ...
