Animal Production Science, 2021
Context Understanding the welfare indicators that affect animal performance can facilitate modifications that improve both animal welfare and profitability. Aims A cross-sectional study was conducted to investigate the prevalence of animal welfare indicators and quantify their possible associations with feed conversion ratio (FCR) and daily feed intake

Residual feed intake of Angus beef cattle divergently selected for feed conversion ratio
Livestock Science, 2010Abstract A divergent selection experiment using feed:gain ratios as the selection criterion was conducted in the early 1980s using Angus beef cattle located at the Eastern Agricultural Research Station (EARS), Belle Valley, OH. Numbers of bulls completing the 140-d postweaning performance test in 1979 through 1983 were 35, 34, 35, 34, and 33 ...

Feed-conversion ratio of finisher pigs in the USA
Preventive Veterinary Medicine, 1998Although the feed-conversion ratio is recognized as a prominent indicator of profitability for pork producers, only 212 (50.7%) of 418 producers who were asked the feed-conversion ratio for finisher pigs provided a response during the USA National Animal Health Monitoring System 1995 National Swine Study.

Feed conversion ratio (FCR), which is used as a description of growth as a function of feed intake, depends mainly on the feeding rate but also on temperature. The estimation of the FCR is simple; however, the practical application of this ratio is limited to cases in which fish are fed beyond maintenance rate.

Feed Conversion Ratio, Profitability and Farm Size in China’s Pig Industry
Research Papers in Economics, 2015The paper is based on a survey we have designed to document the feeding practices in China’s hog industry. We estimate the live weight FCR to be 2.99, in which commercialized farms (>500 head/year) are the most efficient with FCR of 2.73, followed by specialized farms (50-499 head/year) of 2.90, and the main inefficiency in feeding comes from ...

Effects of Feeding Tryptophan-limiting Diets on the Conversion Ratio of Tryptophan to Niacin in Rats
Bioscience, Biotechnology, and Biochemistry, 1996We investigated the effects of feeding various types of nicotinic acid-free, tryptophan-limiting diets on the conversion ratio of tryptophan to niacin in rats. Various tryptophan-limiting diets were made by adding zein, gelatin, glycine, threonine, methionine, or glycine + threonine + methionine to a nicotinic acid-free, 9% casein diet.

Abstract The aim of the study was to derive the economic value (s) (EVs) of growth rate, feed intake, feed conversion ratio, mortality and uniformity for Nile tilapia (Oreochromis niloticus). A smallholder production system where fish are cultured in earthen ponds and oxygen is a limiting factor for production, was simulated using a deterministic bio-
