The effects of plastic slatted floor and a deep- litter system on the growth performance of hybrid Pekin ducks [PDF]

open access: yesArchives Animal Breeding, 2021
This research was conducted to evaluate the effects of plastic slatted floors and a deep-litter system using wood shavings on the growth performance of current commercial hybrid Pekin ducks. A total of 96 Pekin ducks (Star 53) were reared for 42 d. Live

Genomic divergence during artificial selection by feed conversion ratio in Pekin ducks

open access: yesAnimal Biotechnology, 2021
Pekin ducks are world-famous for its fast growth and have become the majority of breeds rearing in duck industry. Feed conversion ratio (FCR) is an important trait in Pekin ducks breeding and production, and the underlying biological processes are complex.

Effect of different weight start of feed restriction and re-feeding on growth performance and carcass traits of Lori lambs [PDF]

open access: yesپژوهش های علوم دامی, 2022
Introduction: Compensatory growth is actually a physiological process in which the animal's potential, after a period of dietary restriction, can be exploited to increase growth and growth efficiency during the free feeding period (Hornick et al 2000 ...

Experimental comparison between selection for residual feed consumption and feed conversion ratio in Tribolium

open access: yesJournal of Animal Breeding and Genetics, 1998
SummarySelection for residual feed consumption based on genotypic regression (RE) was compared with selection for feed conversion ratio (RA) using two experiments of downward selection for feed efficiency in Tribolium castaneum. The first experiment was designed to decrease feed consumption: weight gain, with residual feed consumption being based on ...

Feeding of by-products completely replaced cereals and pulses in dairy cows and enhanced edible feed conversion ratio [PDF]

open access: yesJournal of Dairy Science, 2015
When fed human-edible feeds, such as grains and pulses, dairy cows are very inefficient in transforming them into animal products. Therefore, strategies to reduce human-edible inputs in dairy cow feeding are needed to improve food efficiency. The aim of this feeding trial was to analyze the effect of the full substitution of a common concentrate ...
