Impacts of temperament on Nellore cattle: Physiological responses, feedlot performance, and carcass characteristics
(2015-11-01)
Forty-four feedlot-finished Nellore cattle were used to evaluate the impacts of temperament on performance, meat and carcass traits, and serum concentrations of hormones, proteins, enzymes, and immunoglobulins. Individual ...
Genomic Heritability and Genome-Wide Association Studies of Plasma Metabolites in Crossbred Beef Cattle
(Frontiers Media Sa, 2020-09-24)
Metabolites, substrates or products of metabolic processes, are involved in many biological functions, such as energy metabolism, signaling, stimulatory and inhibitory effects on enzymes and immunological defense. Metabolomic ...

Evaluation of an inexpensive needle test for the diagnosis of phosphorus deficiency and management of phosphorus supplementation for cattle: A multiple case study
(Academia Brasileira de Ciências, 2018)
ABSTRACT The needle test (NT) is a point-of-care test developed in Brazil to evaluate the Phosphorus (P) status in cattle. Based on bone resistance, the NT is a very inexpensive method which allows the diagnosis of any ...
Estimation of segregation variance for birth weight in beef cattle
(Elsevier, 2002-08)
Genetic evaluation using multibreed covariance theory requires estimating the segregation variance. The segregation variance is the amount by which the additive variance in the F2 exceeds that in F1. The goal of this ...
Evaluation of TFAM and FABP4 gene polymorphisms in three lines of Nellore cattle selected for growth
(Funpec-editora, 2010-01-01)
We analyzed the polymorphisms TFAM HaeIII, TFAM MboI and FABP4 MspA1I in three Nellore lines selected for growth in order to evaluate how selection affects the frequencies of these polymorphisms and evaluate their association ...
