In vitro-produced Bos taurus indicus (zebu) and Bos taurus indicus × Bos taurus taurus (cross-bred) embryos behave differently when vitrified. The present experiment aimed to examine the effect of vitrification on embryos produced in the presence or absence of FCS.

Reproductive traits and preweaning growth of progeny from young Hereford, Red Poll, Hereford X Red Poll, Red Poll X Hereford, Angus X Hereford, Angus X Charolais, Brahman X Hereford and Brahman X Angus dams were evaluated. First-calf heifers were mated with Red Angus bulls; Santa Gertrudis sires were used for each cow's second and third breeding season.

The objective of this study was to evaluate the effects of treatment with an intravaginal progesterone-releasing device (CIDR) and estradiol benzoate (EB) on follicular dynamics in Bos indicus (n=23), Bos taurus (n=25), and cross-bred (n=23) heifers. To assess the influence of reduced serum progesterone concentrations during 8 days of treatment with a ...

Heterosis in Bos taurus × Bos indicus crosses
Livestock Production Science, 1985Abstract 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 ...

Summary Amount of circumocular pigmentation and incidence of ocular squamous cell tumors were evaluated in dams representing diverse cattle breed types. Each dam was examined twice annually during a specific stage in the life cycle (3.5 to 9.5 years old). Overall, 28.3% of dams in the herd developed at least 1 ocular squamous cell tumor.

The article is devoted to the description of the Bos taurus domesticus from the old Russian city of Voin (XI???XII) centuries that was situated in the forest-steppe zone of the present-day Ukraine. Altogether 29.5 thousands of bones were determined during excavations. These bones belonged to 500 individuals at the minimum. Adult animals amounted to 4/5
