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.

International Journal for Parasitology, 2010
Bos taurus indicus cattle are less susceptible to infestation with Rhipicephalus (Boophilus) microplus than Bos taurus taurus cattle but the immunological basis of this difference is not understood. We compared the dynamics of leukocyte infiltrations (T cell subsets, B cells, major histocompatibility complex (MHC) class II-expressing cells ...

Tropical Animal Health and Production, 2020
The climate-related problems that affect animal production in tropical countries have encouraged seeking solutions to increase herd productivity and one alternative is the use of breeds adapted to high-temperature environments. The objective of this study was to evaluate the effect of temperature on 77 Caracu and Nelore males submitted to three ...

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 ...

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,
