Genomic Regions Associated with Feed Efficiency Indicator Traits in an Experimental Nellore Cattle Population
(Public Library Science, 2016-10-19)
The objective of this study was to identify genomic regions and metabolic pathways associated with dry matter intake, average daily gain, feed efficiency and residual feed intake in an experimental Nellore cattle population. ...
Suplementación con cobre: efectos en indicadores reproductivos y productivos en un rodeo de cría bovina en el noroeste de ChubutCopper supplementation: effects on reproductive and productive indicators in a cattle breeding herd in northwestern Chubut
(Asociación Argentina de Producción Animal, 2022-11-16)
El cobre (Cu) es un nutriente mineral esencial. Su deficiencia en los rumiantes es frecuente tanto a nivel mundial como a nivel país (Postma et al., 2010). Se ha demostrado deficiencia primaria y secundaria de Cu en bovinos ...
Fumonisins in brewers grain (barley) used as dairy cattle feed in the State of Bahia, Brazil
(2007)
Fumonisins are mycotoxins produced by the genus Fusarium that may induce toxic effects in several animal species and may be found in several kinds of foods and feed. In the State of Bahia, Brazil, brewers grain, which are ...
Supplementing an immunomodulatory feed ingredient to improve thermoregulation and performance of finishing beef cattle under heat stress conditions
(2019-10-03)
This experiment compared physiological and productive responses in finishing beef cattle managed under heat stress conditions, and supplemented (SUPP) or not (CON) with an immunomodulatory feed ingredient (Omnigen-AF; ...
Selection criteria for feed efficiency-related traits and their association with growth, reproductive and carcass traits in Nelore cattle
(2021-01-01)
Context: Livestock feed costs have a higher impact on the profitability of beef production systems and are directly related to feed efficiency. However, these traits are hard and have high costs to measure, reducing the ...

Residual feed intake: un indicador de eficiencia que se instala en la ganadería bovina argentina
(Ediciones INTA, 2022-05)
La conversión de alimento a producto –carne o leche– es el principal condicionante del negocio ganadero bovino, en particular en la alimentación a corral con granos y subproductos. En este artículo se revisa el impacto de ...
Circulating leptin and its muscle gene expression in Nellore cattle with divergent feed efficiency
(BioMed Central, 2017)
Abstract
Background
Leptin has a strong relation to important traits in animal production, such as carcass composition, feed intake, and reproduction. It is mainly produced ...
Circulating leptin and its muscle gene expression in Nellore cattle with divergent feed efficiency
(Biomed Central Ltd, 2017-09-01)
Background: Leptin has a strong relation to important traits in animal production, such as carcass composition, feed intake, and reproduction. It is mainly produced by adipose cells and acts predominantly in the hypothalamus. ...
