Influence of the breed of bull (Bos taurus indicus vs. Bos taurus taurus) and the breed of cow (Bos taurus indicus, Bos taurus taurus and crossbred) on the resistance of bovine embryos to heat

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 ...

223 PREANTRAL FOLLICLES POPULATION IN BOS TAURUS INDICUS AND BOS TAURUS TAURUS FEMALES

Reproduction, Fertility and Development, 2010
Bos 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. Our objective was to test the hypothesis that the difference in oocyte yield is a

Output/input differences among nonpregnant, lactating Bos indicus-Bos taurus and Bos taurus-Bos taurus F1 cross cows.

Journal of Animal Science, 1991
Nonpregnant F1 crossbred cows, progeny of either Hereford (H) or Angus (A) dams and sired by Brahman (Bm), Sahiwal (Sw), Pinzgauer (Pz), H, or A sires, were fed to maintain initial weight while rearing Charolais (C)-sired progeny for a period of 126 d in drylot commencing at about 48 d postpartum.

Composition and Yield of Milk from Beef-Type Bos Taurus and Bos Indicus × Bos Taurus Dams

Journal of Animal Science, 1987
Yield, 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,

38 VITRIFICATION OF BOS TAURUS INDICUS AND BOS TAURUS INDICUS×BOS TAURUS TAURUS EMBRYOS PRODUCED IN THE PRESENCE OR ABSENCE OF FETAL CALF SERUM

Reproduction, Fertility and Development, 2012
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.

Neoplasms in Calves (Bos taurus)

Veterinary Pathology, 1982
From 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.

Effect of high temperature on physiological parameters of Nelore (Bos taurus indicus) and Caracu (Bos taurus taurus) cattle breeds

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 ...

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 ...

Cryotolerance and global gene-expression patterns of Bos taurus indicus and Bos taurus taurus in vitro- and in vivo-produced blastocysts

Reproduction, Fertility and Development, 2014
In a 2 × 2 factorial experimental design, embryo development, cryotolerance and global gene expression of Nellore (Bos taurus indicus) and Simmental (Bos taurus taurus) blastocysts produced in vitro (IVP) and in vivo (multiple ovulation derived embryo, MODE) were assessed. Blastocyst production was higher in Nellore than in Simmental (47.7 ± 2.0% vs 27.
