Residual feed intake (RFI) is a measure of feed efficiency that is independent of level of production, such as size and growth rate in beef cattle, and thus is a useful new trait for studying the physiological mechanisms underlying variation in feed efficiency. Five major physiological processes are likely to contribute to variation in RFI, these being processes associated with intake of feed, ...

            In this study, rainbow trout were fed for a total of 144 days with different feed mixes containing 0.00%, 0.10%, 0.40%, 0.70%, 1.00% and 1.30% black cumin oil. The effect of black cumin oil on the growth performance, feed content and fatty acid composition of rainbow trout was researched. The starting weight of fish in the experimental group was approximately 60 gr., which increased...

Feed is the largest single cost of producing beef. Producers who have access to alternative feeds often have economic advantages due to the lower costs of production. However, alternative feeds can present challenges due to variable consistency, variable supply, potential toxicants, and unusual composition. Rice straw, a by-product of the rice grain industry in Northern California, is a potenti...

in this study, the effect of garlic extract on the growth performances ( body weight increase (bwi), specific growth rate (sgr), condition factor (cf), final length (fl) and weight (fw)), feed indices (feed conversion rate (fcr), protein efficiency ratio (per), protein production ratio (ppr)) and body composition (protein, fat, moisture and ash) of mugil cephalus larvae were studied in four tre...

an experiment was conducted to predict the true metabolizable energy (tmen) of compounded starter feeds of broiler chickens trough their chemical composition using precision-feeding method of sibbald in male boilers. in the first, eight compounded feed samples provided from eight feed plants and their chemical composition determined in laboratory. results of chemical composition showed that ave...

P arallel process units are often encountered in chemical process systems for different considerations, e.g., parallel reactors from reactor network synthesis, parallel columns for heat integration. One notable example is the feed split configuration of heatintegrated distillation columns. In this work, the control of parallel processes is illustrated with the heat-integrated distillation colum...

Sustainable feed formulation (defined here as nutritional and economic feed optimization) is substantial in feed chain production from crop farmers to livestock producers. Diet formulation employing a static linear programming (LP) approach, which is widely used in trading firms and feed production facilities, does not allow for intertemporal flexibility. Our approach allows the interaction bet...

In recent years, the development of ”News Feed” interfaces have transformed the ways in which individuals seek and encounter information in social network sites. Rather than primarily searching for information, a networked information feed provides a constantly updated stream of information about ongoing activity in the networked community. In the following paper, the components of networked in...

This study was conducted to determine the chemical composition and nutritive value of sunflower residues silage (SRS) and effects of its substitution with alfalfa hay and corn silage on lactation performance, feed intake, nutrient digestibility and some blood parameters of Mohabadi dairy goats. Four experimental diets were formulated to gradually replace alfalfa hay and corn silage with SRS as ...

Currently, artificial neural networks (ANN) are being applied to livestock production as alternatives to regression analysis for forecasting egg prices [1, 2], selecting the feed mix in the feed industry [3], and predicting the amino acid composition of feed ingredients [4, 5]. The advantages of ANN have been reported. Unlike regression analyses, ANN do not require that a mathematical model be ...
