Feed intake and efficiency are economically important traits because feed is the greatest variable cost in beef production. Feed efficiency can be measured as residual feed intake (RFI), which is the difference between actual DMI of an animal and the expected DMI based on its BW and growth rate. Feed conversion ratio (FCR) is the inverse of gross feed efficiency and is the ratio of DMI to ADG. ...

In this work, the backward Bayesian multiple linear regression (BBMLR) as a new approach is presented to predict the adsorption efficiency (AE) of Cd(II) ions by ostrich bone char (OBC) in the fixed bed adsorption with four operational variables consisting of pH (2-9), inlet Cd(II) concentration (Co= 25-100 mg/L), bed depth (h= 3-9 cm) and feed flow rate (Q= 0.5-30 mL/min). The performance of t...

the aim of the present study was to compare different periods of feed deprivation (day number of starvation in four physical feed restriction programs) on total immunuglobulins and lymphocytes percentage in pullets and cockerels of broiler breeder. a 4x2 factorial experiment based on a completely random design. 160 pullets and 160 cockerels of broiler breeder. feed intake content weekly was the...

Background and purpose: Nonlinear analysis methods for quantitative structure–activity relationship (QSAR) studies better describe molecular behaviors, than linear analysis. Artificial neural networks are mathematical models and algorithms which imitate the information process and learning of human brain. Some S-alkyl derivatives of thiosemicarbazone are shown to be beneficial in prevention and...

FEED manufacturers are often forced by circumstances to focus on short-term concerns such as: How many tons were produced this week? How many customers do I have, or how much down time did I have this week? While important, short-term problems can cause manufacturers to focus on solving problems rather than pursuing the company’s mission. Manufacturers who regularly examine their company’s miss...
