Y chromosome variants in cattle Bos taurus and Bos indicus [PDF]
Genetics Selection Evolution, 1982 Summary It is shown that comparison of the size of the Y chromosome between individuals may be made as reliably by computation of measurement relative to the X chromosome as by proportionation relative to the genome in the cell. By either method agreement was found with previous studies : first in placing the Y in the size range, for the cattle ...

Trace element nutrition in the tropical zebu cattle type : lessons from the Gilgel Gibe catchment, Ethiopia [PDF]
, 2014 In the tropics, cattle are majorly dependent on natural pastures growing on poor soils and as a result prone to trace element deficiencies. This work investigated several aspects of trace element nutrition in zebu (Bos indicus) cattle, the most widely ...

Sexual development in early- and late-maturing Bos indicus and Bos indicus × Bos taurus crossbred bulls in Brazil [PDF]
Theriogenology, 2004 Two experiments were conducted to evaluate sexual development in early- and late-maturing Nelore (Bos indicus) and Canchim (3/8 Bos indicus x 5/8 Bos taurus crossbred) bulls and to determine predictors of sexual precocity, and pubertal and maturity status. In Experiment 1, 12 Nelore bulls where examined from 300 to 900 days of age.

Cattle phenotypes can disguise their maternal ancestry
BMC Genetics, 2017 Background Cattle are bred for, amongst other factors, specific traits, including parasite resistance and adaptation to climate. However, the influence and inheritance of mitochondrial DNA (mtDNA) are not usually considered in breeding programmes.
