A nonlinear programming optimization model was developed to maximize margin over feed cost in broiler feed formulation and is described in this paper. The model identifies the optimal feed mix that maximizes profit margin. Optimum metabolizable energy level and performance were found by using Excel Solver nonlinear programming. Data from an energy density study with broilers were fitted to quad...

Feed management in shrimp culture aims to improve the quality of organisms. The application feeding regime has been developed determine best formulation diet order maximize growth rate and survival by increasing feed efficiency minimizing waste. is closely related understanding physiological morphological aspects from larval stage adult stage. success with will be a solution problem high costs ...

There is an increasing need in the aquaculture industry for more sustainable and functional feed concepts marine finfish. This study provides results effect of alternative formulations on health status, welfare parameters, sensory analysis, growth performance European seabass (Dicentrarchus labrax) over 83-day feeding trial. Fish were fed twice a day with five experimental diets. A control diet...

A 90 day study was conducted on twenty four indigenous non-descript goats allocated into four groups. They were fed ad libitum basal complete feed constituted rice straw: rhea (60:40) grass hay and concentrate mixture @ 250/animal/day. Basal complete feed contain 11.07% DCP and 54.21% TDN. Groups were control (T0) basal diet without polyherbal supplementation, treatment 1 (T1) diet with Ruchama...

The aim of present experiment was to investigate the effect of protein reduction in commercial broiler chicken rations with incorporation of de-oiled rice bran (DORB) and supplementation of limiting amino acids (valine, isoleucine, and/or tryptophan) with ration formulation either on total amino acid (TAA) or standardized ileal digestible amino acids (SIDAA). The experimental design consisted o...

The results of this project have lead to several improvements in the costeffectiveness of diet formulations and feeding schedules for channel catfish. Advancements in these areas will significantly improve production economics by reducing diet costs and increasing the eff iciency of feed utilization. The benefits obtained from these advancements will be substantial because over one-half of the ...

A revised enzyme synthesis rate expression for cybernetic models of bacterial growth is presented. The rate expression, which is comprised of inducible and constitutive contributions, provides for a basal enzyme level that is necessary to predict certain types of commonly observed continuous culture transients. The response of a continuous culture to a step change in feed stream composition is ...

The purpose of this study was to determine the implementation Etawa Goat farming techniques in research area, as well analyze livestock business feasible be cultivated and find out obstacles faced by farmers efforts made overcome these obstacles. results concluded that cultivation technique at TAMI FARM Ranch carried intensively, namely goats were kept cages continuously, feeding three times a ...

Insect meals are promising alternative feed ingredients although their application is still not commonplace. Their inclusion requires the consideration of various factors to optimise growth, animal welfare, and costs. The insect meal form (whole or defatted) impacts level inclusion, in particular feeds where low amount lipids needed (e.g. poultry). From a nutritional point view, that influence ...
