Feed efficiency(FE) is the ratio of mean dailyweight gainto mean daily feed consumption over a given period (Gilbert, 2015). It can also be expressed as the ratio of growth to energy intake, which depends less on energy density in the diet. However, in practice, the inverse of FE is ...
feed efficiency 英[fi:d iˈfiʃənsi] 美[fid ɪˈfɪʃənsi] 释义 饲料效率,饲料转化效率 实用场景例句 全部 Effects of galactooligosaccharides ( GOS ) onfeed efficiencyand calcium absorption ratio in mice were investigated.
Ratio efficiency traits included energy conversion ratio (ECR), Kleiber ratio (ADG/BW), relative growth rate (RGR), residual EI (REI), and residual daily gain (RDG). Residual intake and gain (RIG; i.e., a dual index of both REI and RDG) and residual midtest metabolic weight (RMW) ...
2]. Feed conversion ratio and residual feed intake are two traits that have been routinely used to evaluate feed efficiency [3]. An animal with a low feed conversion ratio and low residual feed intake consumes less feed per unit of body weight than expected...
3.5.2Feed conversion ratio (FCR) and efficiency of herbage utilisation (EHU) Both Plantain and Chicory mixes had lower (P<0.05) FCR than Pasture mix in both experiments (Table 6).Feed conversion ratiowas not different (P>0.05) between the Plantain and Chicory mixes in both experiments. In...
The efficiency of food use makes a major contribution to the economic sustainability of broiler production (chickens reared for meat), where feed represents the greatest variable cost.4 Feed efficiency can be measured using the feed conversion ratio (FCR), which is a composite trait defined as fe...
average daily gain in rabbits fed ad libitum; ADGR, average daily gain in rabbits fed under restriction; ADFIAL, average daily feed intake in rabbits fed ad libitum; ADRFIAL, average daily residual feed intake in rabbits fed ad libitum; ADFCRAL, average daily feed conversion ratio in rabbits...
Integration of epigenomic and genomic data to predict residual feed intake and the feed conversion ratio in dairy sheep via machine learning algorithms ArticleOpen access31 March 2025 Background Improving feed efficiency (FE) is a priority for most livestock species because it is a key component of...
FCR is the ratio between the total of feed intake and the individual weight gain over a specific time, RFI index was first proposed by Koch et al. (1963) and has successfully applied to the artificial selection of feed efficiency in livestock, which is defined as the difference between ...
This study was conducted to determine the optimum test duration and the effect of missing data on accuracy of measuring feed efficiency and its 4 related traits ADG, DMI, feed conversion ratio, and residual feed intake in beef cattle using data from 456 steers with 5,397 weekly averaged feed...
