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 ...

Local immune response against larvae of Rhipicephalus (Boophilus) microplus in Bos taurus indicus and Bos taurus taurus cattle

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 ...

Culture of preantral ovarian follicles of Bos taurus indicus with alpha-lipoic acid.

Zygote (Cambridge. Print), 2021
The aim of this study was to evaluate follicular development, morphological integrity, and antioxidant potential of preantral ovarian follicles from Bos taurus indicus females grown in vitro with alpha-lipoic acid. Ovaries (n = 24) of Bos taurus indicus (

Effects of vulvar width and antral follicle count on oocyte quality, in vitro embryo production and pregnancy rate in Bos taurus taurus and Bos taurus indicus cows.

Animal Reproduction Science, 2020
It was hypothesized that Brahman cows have greater in vitro embryo production than Simmental cows, and that regardless of breed, antral follicle count (AFC) and vulvar width (VW) are positively associated with oocyte quality, embryo number and pregnancy ...

Importance of temperament in the pregnancy by timed insemination in bovine females Bos taurus indicus

, 2020
The aim of this research was to evaluate the effects of the temperament of bovine females Bos taurus indicus submitted to a timed artificial insemination (TAI) protocol on the concentrations of cortisol, diameter of the largest follicle, pregnancy by TAI

Effect of early luteolysis in progesterone-based timed AI protocols in Bos indicus, Bos indicus×Bos taurus, and Bos taurus heifers

Theriogenology, 2008
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 ...

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

Reproduction, Fertility and Development, 2009
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.
