Multiple regression and machine learning based methods for carcass traits and saleable meat cuts prediction using non-invasive in vivo measurements in commercial lambs
(2019-02-01)
The aim of this study is to investigate the performance of multiple linear regression and machine learning methods to predict carcass traits and commercial meat cuts in lambs using non-invasive in vivo measurements. Bayesian ...
Relationships between temperament, meat quality, and carcass traits in Nellore cattle
(Oxford Univ Press Inc, 2019-12-01)
The aim of this study was to evaluate the relationship between temperament in Nellore bulls with carcass and meat quality traits. In total, 1,400 bulls were studied, and temperament was assessed using two measurements: ...
Common factors method to predict the carcass composition tissue in kid goats
(Sociedade Brasileira de Zootecnia, 2013-03-01)
The objective of this work was to analyze the interrelations among weights and carcass measures of the longissimus lumborum muscle thickness and area, and of sternum tissue thickness, measured directly on carcass and by ...

Fixed-Nitrogen Loss Associated with Sinking Zooplankton Carcasses in a Coastal Oxygen Minimum Zone (Golfo Dulce, Costa Rica)
(2017)
Oxygen minimum zones (OMZs) in the ocean are of key importance for pelagic fixed-nitrogen loss (N-loss) through microbial denitrification and anaerobic ammonium oxidation (anammox). Recent studies document that zooplankton ...
Genetic correlation of traits measured by ultrasound at yearling and 18 months of age in Nellore beef cattle
(2015-01-01)
The objective of this study was to estimate genetic parameters for carcass traits measured by ultrasound at yearling (Y) and 18 months of age (post-yearling, PY) in order to identify the most appropriate age for the ...
Feedlot performance, feed efficiency and carcass traits in Nellore cattle selected for postweaning weight
(Sociedade Brasileira de Zootecnia, 2013-02-01)
The objective of this study was to evaluate the correlated responses to selection for growth in feed efficiency and carcass traits of Nellore animals. A total of 121 animals of the Nellore control (NeC) and selection herds ...
Mapping QTLs on chicken chromosome 1 for performance and carcass traits in a broiler x layer cross
(Blackwell Publishing, 2006-04-01)
With the objective of mapping quantitative trait loci (QTLs) for performance and carcass traits, an F-2 chicken population was developed by crossing broiler and layer lines. A total of 2063 F-2 chicks in 21 full-sib families ...
