Feed efficiency and fecal microbiome of nursery pigs from parents with divergent breeding value for feed conversion ratio. [PDF]

Transl Anim Sci
Abstract Improving feed efficiency (FE) is essential for the swine industry’s economic and environmental sustainability. Genetic selection, particularly through estimating breeding values for feed conversion ratio (EBV_FCR), is a common strategy to enhance FE.

Response to selection for feed conversion ratio in Japanese quail

Poultry Science, 2010
We investigated the effect of selection for 4-wk feed conversion ratio (FCR) on genetic improvement of FCR, BW, weight gain (WG), feed intake (FI), and residual FI (RFI) in Japanese quail. The F line was selected for reduced FCR and the C line was maintained as a randombred control.

Influence of production factors on feed intake and feed conversion ratio of grow-finishing pigs

Semina: Ciências Agrárias, 2017
The aim of this study was to identify and quantify, through mathematical models, the production factors of grow-finishing (GF) phases that influence the daily feed intake (DFI) and feed conversion ratio (FCR) in pigs.

Factors affecting the daily feed intake and feed conversion ratio of pigs in grow-finishing units: the case of a company. [PDF]

Porcine Health Manag, 2016
The aim of this study was to use mathematical modeling to identify and quantify the main factors that affect daily feed intake (DFI) and feed conversion ratio (FCR) in grow-finishing (GF) pig units. We evaluated the production records of 93 GF farms between 2010 and 2013, linked to a company, working in a cooperative system, located in western Paraná ...

Differences in gut microbiota composition in finishing Landrace pigs with low and high feed conversion ratios [PDF]

Antonie van Leeuwenhoek, 2018
The goal of this study was to evaluate the microbial communities in the gut and feces from female finishing Landrace pigs with high and low feed conversion ratio (FCR) by 16S rRNA gene amplicon sequencing. Many potential biomarkers can distinguish between high and low FCR groups in the duodenum, ileum, cecum, colon, and rectum, according to linear ...

Feed Intake and Feed Conversion Ratio of Broiler Supplemented with Herb Extract

IOP Conference Series: Earth and Environmental Science, 2022
Abstract Traditional ingredients from herbal plants can be used as antioxidants because they contain curcumin compounds that can affect the metabolic processes of the livestock body. Herbal are obtained from several rhizomes such as turmeric, ginger, lemongrass, and Curcuma. This study investigated the effects of herbal ingredients added

Genome wide association study on feed conversion ratio using imputed sequence data in chickens. [PDF]

Asian-Australas J Anim Sci, 2019
Feed consumption contributes a large percentage for total production costs in the poultry industry. Detecting genes associated with feeding traits will be of benefit to improve our understanding of the molecular determinants for feed efficiency. The objective of this study was to identify candidate genes associated with feed conversion ratio (FCR) via ...
