Early weaning in pregnant cows as a fetal programming strategy alters the muscle metabotype and carcass traits in Nelore cattle

Matheus Sousa de Paula Carlis, Gabriela Abitante, T. Nishimura, Carl R Dahlen et autres

Abstract This study evaluated early weaning (EW) versus conventional weaning (CW) and dam parity (DP) effects on carcass traits, meat quality, and the muscle metabolome of male offspring exposed in utero during the intervention. A randomized complete-block design with a 2 × …

Polymorphism in the Calpastatin Gene Alters Beef Tenderization in Excitable Cattle: A Preliminary Study

Ana Cláudia da Silva, Patricia Maloso Ramos, Aline Silva Mello César, João Pedro Sousa do Vale et autres

The variability in beef tenderness is a problem for industry and can be difficult to overcome, especially for Bos taurus indicus cattle. The objective of this study was to determine the association between calpastatin (CAST) polymorphisms (Single Nucleotide Polymorphism, SNP) and tenderness …

Guanidinoacetic Acid and Its Impact on the Performance, Carcass and Meat Quality of Growing and Finishing Nellore Cattle

Letícia Carolina Bortolanza Soares, Longjie Huang, Germán Darío Ramírez-Zamudio, Murilo Soler de Magistri et autres

This study evaluated the effects of guanidinoacetic acid (GAA) supplementation during the growing and finishing phases on Nellore bulls’ performance, carcass traits, and meat quality. Fifty-two Nellore bulls were randomly assigned to four treatments: control (CON, without GAA) and three GAA levels …

Temperament Upregulates Mitochondrial Enzymes and Negatively Affects Myofibrillar Fragmentation in Beef of Excitable Bos taurus indicus Cattle

Patricia Maloso Ramos, Eduardo Francisquine Delgado, Ana Cláudia da Silva, Nara Regina Brandão Cônsolo et autres

Background: Bos taurus indicus cattle is known to be temperamental and to produce beef with greater variability in terms of quality compared to beef of Bos taurus taurus. Cattle adaptability and resilience are of great importance to sustain beef production worldwide. Objective: …

Expression of calpain system transcripts responds inversely to beef tenderization after vitamin D3 supplementation in Nellore cattle

Lilian Ribeiro Rezende, Patricia Maloso Ramos, Adalfredo Rocha Lobo Júnior, Gustavo Gasparin et autres

ABSTRACT The calpain system is the central player for meat tenderization and the calpastatin activity plays an important role in beef tenderness of Bos taurus indicus cattle. This study investigated whether dietary vitamin D3 induced gene expression of μ-calpain (CAPN1), total calpastatin …

PSXII-19 Organ and cellular contributions to heat production in Brahman and Angus steers

Briana Hawryluk, Morgan McKinney, Chloe A Gingerich, Lindsey C. Bell et autres

Abstract Reductions in basal metabolism and growth rate appear to contribute to decreased heat production of Bos indicus breeds. Lower metabolic rate may be due to smaller organ size and lower metabolic activity. Liver and heart account for high percentage of metabolic …

Early Postmortem Metabolism and Protease Activation in Fast Glycolytic and Slow Oxidative Bovine Muscles

Patricia Maloso Ramos, Mayka Reghiany Pedrão, Lindsey C. Bell, Tracy L. Scheffler

Muscle properties and metabolism influence muscle to meat conversion. Fiber type profile impacts glycolytic capacity as well as protein turnover rate in vivo. Our objective was to investigate protease content and activation during the early postmortem period using muscles with known divergent …

Beef of Nellore cattle has limited tenderization despite pH decline in Longissimus lumborum

Patricia Maloso Ramos, Priscila R. dos Santos-Donado, Giuliana Micai de Oliveira, Carmen J. Contreras‐Castillo et autres

Bos taurus indicus temperament is variable and affects beef tenderization. Our objective was to investigate temperament and performance of non–castrated Nellore and identify groups based on Longissimus lumborum (LL) pH decline as well as beef characteristics produced by those groups. We investigated …
