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.

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 ...

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.

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.

Novel insight into the feed conversion ratio in laying hens and construction of its prediction model. [PDF]

Poult Sci
Feed efficiency (FE) is an important economic factor in poultry production, and feed conversion ratio (FCR) is one of the most widely used measures of FE. Factors associated with FCR include genetics, the environment, and other factors. However, the mechanisms responsible for FCR in chickens are still less well appreciated.

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

Feed Intake and Feed Conversion Ratio of Ongole Crossbred Cattle Fattened at Different Ages and Feed

KnE Life Sciences, 2022
This research aimed to determine the effect of the dietary treatments and age on the fattening process in cattle. Thirty-six Ongole crossbred cattles were allotted into two different dietary treatments and three different age groups, with six replications for 24 weeks period, 4 weeks of preliminary followed by 20 weeks of data collection at the Beef ...
