Effects of scrotal insulation on sperm production, semen quality, and testicular echotexture in Bos indicus and Bos indicus × Bos taurus bulls

Animal Reproduction Science, 2003
The objectives of the present study were to evaluate the effects of scrotal insulation on sperm production, semen quality, and testicular echotexture in Bos indicus and Bos indicus x Bos taurus crossbred bulls. In one experiment, B. indicus bulls (n=12) were allocated to control and whole-scrotum insulation groups, while in a second experiment ...

Endometrial biopsy inBos indicusbeef heifers

Reproduction in Domestic Animals, 2017
ContentsAn endometrial biopsy allows for a comprehensive assessment of the uterine environment of a breeding female. Although routine in mares, devices used for endometrial biopsies are impracticable in heifers due to the size and structure of the cervix.

Cryopreservation of bos taurus vs bos indicus embryos: are they really different?

Theriogenology, 2002
Cryopreservation with storage at very low temperatures is essential to make full use of this technology for both biological and commercial reasons. However, most mammalian cells will die if exposed to these temperatures unless they are exposed to cryoprotectant solutions and cooled and warmed at specific rates.

Spermatogenesis in Bali cattle (Bos sondaicus) and hybrids with Bos indicus and Bos taurus

Research in Veterinary Science, 1990
Semen quality, testis size and efficiency of sperm production in Bali cattle (Bos sondaicus) and hybrids with Bos indicus and Bos taurus were determined. Mean (+/- SEM) daily sperm production per gram of testis parenchyma (DSPG) in six purebred Bali bulls was 12.2 +/- 0.7 x 10(6).

Identification of genes involved with tick infestation in Bos taurus and Bos indicus.

Developments in biologicals, 2008
Tick resistant cattle could provide a potentially sustainable and environmentally sound method of controlling cattle ticks. Advances in genomics and the availability of the bovine genome sequence open up opportunities to identify useful and selectable genes controlling cattle tick resistance.
