The karyotype of Bos indicus is identical with that of Bos taurus except for the morphology of the Y chromosome. The Y chromosome of B. taurus is a small metacentric, but that of B. indicus is a small acrocentric. Autoradiographs of DNA synthesis during the late S phase invariably show a late replicating small acrocentric.

Acquisition and Expression of Resistance by Bos indicus and Bos indicus x Bos taurus Calves to Amblyomma americanum Infestation [PDF]
The Journal of Parasitology, 1985 Purebred and crossbred Bos indicus calves were infested 1, 2, or 3 times with 10 female and 5 male Amblyomma americanum. Resistance was acquired by both the purebred and the crossbred calves after 1 infestation and resulted in statistically significant decreases in the percentages of females that engorged, the mean weights of engorged females, and the ...

Tropical Animal Health and Production, 2023
Fertility is an important trait associated with reproductive performance and animal welfare concern. Lethal alleles affect fertility through early embryonic death, abortions, and stillbirth depending on the genetic expression of the allele. Holstein Friesian and Jersey are two major Bos taurus breeds used widely for increasing milk yield along with ...

Reproductive cycles in Bos indicus cattle
Animal Reproduction Science, 2011Several studies using transrectal ovarian ultrasonic scanning in Bos taurus (B. taurus) cattle and more recently in Bos indicus (B. Indicus) females evaluated the reproductive cycles of heifers and cows under different conditions. In general, B. indicus cattle have more follicles and more follicular waves during the estrous cycle and ovulate from ...
