Challenges of beef cattle production from tropical pastures [PDF]

Revista Brasileira de Zootecnia, 2018
The live weight gain of cattle on tropical pastures is reviewed and found to be low and dependent on the length of the growing season. Supplements may be added to address the primary limiting nutrient, which, in the dry season, is crude protein.

Multi-breed genomic evaluation for tropical beef cattle when no pedigree information is available [PDF]

Genetics Selection Evolution, 2023
Background It has been challenging to implement genomic selection in multi-breed tropical beef cattle populations. If commercial (often crossbred) animals could be used in the reference population for these genomic evaluations, this could allow for very ...

Genetic Architecture of Carcass and Meat Quality Traits in Montana Tropical® Composite Beef Cattle

Frontiers in Genetics, 2020
The Montana Tropical® Composite is a recently developed beef cattle population that is rapidly expanding in Brazil and other tropical countries. This is mainly due to its improved meat quality and adaptation to tropical climate conditions compared to ...

The Welfare Impact of Heat Stress in South American Beef Cattle and the Cost-Effectiveness of Shade Provision [PDF]

Animals
Heat stress represents a pervasive welfare challenge for beef cattle and other species in tropical and subtropical regions. While its physiological and production impacts are well-documented, quantitative measures of the welfare impact of heat stress ...

Effect of incremental proportions of Desmanthus spp. in isonitrogenous forage diets on growth performance, rumen fermentation and plasma metabolites of pen-fed growing Brahman, Charbray and Droughtmaster crossbred beef steers.

PLoS ONE, 2022
Desmanthus (Desmanthus spp.), a tropically adapted pasture legume, is highly productive and has the potential to reduce methane emissions in beef cattle.

Tropical Beef: Is There an Axiomatic Basis to Define the Concept?

Foods, 2021
Cattle production in tropical regions has been estimated to account for just over half of cattle worldwide, yet it has not been demonstrated that sufficient similarities in the cattle exist to describe tropical cattle and, even less so, to characterize ...

Genetics and nutrition impacts on herd productivity in the Northern Australian beef cattle production cycle

Veterinary and Animal Science, 2022
Genetics and nutrition drive herd productivity due to significant impacts on all components of the beef cattle production cycle. In northern Australia, the beef production system is largely extensive and relies heavily on tropical cattle grazing low ...

Feedlot growth performance and carcass characteristics of steers backgrounded on buffel grass or buffel–Desmanthus mixed pastures

Frontiers in Veterinary Science, 2022
Feedlot performance and carcass characteristics of tropical beef steers backgrounded on buffel grass (Cenchrus ciliaris) only or buffel grass oversown with desmanthus (Desmanthus spp. ; 11.5% initial sward botanical composition) were evaluated.
