Bos indicus composite and Bos taurus cattle, originating from diverse production environments, were used to quantify genetic variation in marbling, 24-h calpastatin activity, and beef tenderness and to identify strategies for prevention of beef tenderness problems in Bos indicus composite cattle.
Also, beef from 3/8 Bos indicus composites aged more slowly from 1 to 7 d and was less tender at 4, 7, 14, 21, and 35 d postmortem than beef from Bos taurus cattle.
The delayed response to aging and greater toughness of beef from 3/8 Bos indicus cattle was associated with Brahman breed effects and was not related to the Bos taurus germplasm source.

 What Is Systematic Crossbreeding?
Bos indicus x Bos taurus crosses (i.e., Brahman x Hereford) yield even higher levels of heterosis, averaging double the pounds of calf weaned as those reported for corresponding traits among straightbred Bos taurus breeds.
In the hot, humid Gulf Coast, 50:50 ratios of Bos indicus to Bos taurus inheritance may be optimal.
For example, if the optimum level of Bos indicus germplasm is 25% for a specific environment, the contribution of Bos indicus can be maintained at 25% in a composite population.

 Zebu - Wikipedia, the free encyclopedia
Zebus (Bos taurus indicus), sometimes known as 'humped cattle', are better-adapted to tropical environments than other domestic cattle.
Their scientific name was originally Bos indicus, but this name is now deemed invalid by ITIS, who classify the zebu under Bos taurus along with all other domestic cattle, and their aurochs ancestors, domesticated in India about 10,000 years ago.
The Aurochs subspecies Bos primigenius namadicus or even the gaur may have contributed to the development of the zebus.

 Crossbreeding bos indicus and bos taurus for milk production in the tropics
In parallel with these broad differences in numbers and productivity of dairy cows between the developed and developing worlds, there is also a major difference in cattle types: Bos taurus breeds being exclusively used in temperate and developed areas, while Bos indicus types predominate numerically throughout most of the developing world (Figure 1.1).
The genetic difference between taurus and indicus types therefore is roughly equivalent to the gain achievable from 100 years of sustained and highly efficient selection within a population.
Bos taurus types usually fail to produce adequately, and often even to survive, in the face of the multiple challenges of climatic stress, new diseases and parasites, and nutritional insufficiency.

Therefore Bos indicus content was an integral part of the carcass pathways where there were maximum breed contents allowed in various pathways.
Bos indicus content must be declared by the supplier as either less tha 12%, less than 25%, less than 50%, less than 75% or greater than 75% Bos indicus.
This declaration is to be made on the 'Meat Standards Australia Vendor Declaration' by ticking the appropriate box along with identifying the animal in the lot with the highest known or visual Bos indicus content by its ear tag number and stating its breed make-up.

 American Romagnola Association
Manifestations of their Bos Indicus lineage include the ability of the Romagnola to sweat and to secrete an oily fluid from their sebaceous glands that is useful in repelling insects.
Like their conventional Bos Indicus cousins, they also have a muscle network in their hides that allows them to twitch their skins, also handy for removing biting flies and mosquitoes.
In addition, they are more heavily muscled, a gift of their Bos Taurus ancestors as well as a history of use as draft animals in Italy which put a large quantity of muscle over the back and loin where the choice cuts of beef are located.

 8. The formation of composite breeds using Sahiwal cattle
Breeds of Bos indicus cattle differ, in response capability for both milk and meat production and also in their adaptability to climate and associated factors, including tolerance of different diseases and parasites.
Certain populations of Bos taurus cattle in Africa and South America have become adapted to adverse conditions through natural selection, but, similar to Bos indicus breeds, they have a relatively low response capability for milk and meat production when environmental conditions are improved.
It is also assumed that the Sahiwal breed is approximately equal to indigenous breeds of Bos indicus cattle in terms of adaptability in the ecological zones of Africa that are the focus of this study.

ABSTRACT Ten Bos indicus × MARC III (initial BW = 303 ± 25 kg) and 10 MARC III (initial BW = 322 ± 16 kg) steers were used in a 2 × 2 factorial design to determine whether cattle age or Bos indicus crossbreeding influence site of digestion of a high-grain diet.
Initially, five Bos indicus × MARC III and five MARC III steers were fitted with duodenal cannulas and adapted to a 95% concentrate diet that was offered for ad libitum consumption for a 237-d feeding period (calves).
Similar feedlot performance would be expected by Bos indicus crossbred and Bos taurus steers, although performance by Bos indicus crossbred steers may be greater in subtropical environments.
