OBJECTIVE This study aimed to assess the effect of pelleted and expanded sorghum-based feeds prepared with different moisture levels and particle size of ingredients on metabolizable energy, ileal digestibility of amino acids and broiler performance. METHODS The experiment was performed with 720 male broiler chicks of the Cobb strain, with treatments of six replications, with 15 birds each; t...

Processing feed onfarm using a portable grinder-mixer provides an affordable and flexible manufacturing system for producers with small to intermediate size operations (50 to 400 farrow to finish sows). The portable grinder-mixer differs from a stationary mill in several important areas during feed processing. These differences will be considered by examining five functions or cost centers in a...

in this study, the effects of culban seed (vicia peregrine l.) on live body weight, feed intake, feed efficiency, egg production, egg quality characteristics, egg yolk fatty acid profiles and yolk cholesterol content in laying hens were investigated. the experiment consists of seven treatment groups with ten replications containing one laying hen in each and for 32 weeks old seventy laying hen ...

this study was conducted to investigate the effects of dietary nigella sativa meal (nsm) on the growth performance, blood parameters, carcass characteristics, egg yolk cholesterol and meat quality in japanese quail. for this purpose 300 one-day old japanese quail chicks in a completely randomized design was used with five treatments in four replicates )containing 15 birds each(. the experimenta...

To control the quality of reverse osmosis (RO) product water and reduce operational costs and environmental impacts by increasing the system’s energy efficiency, it is necessary to identify the influence of process parameters on energy consumption and permeate water quality. This paper introduces a case study focused on the application of Design of Experiments (DOE) method in an industrial-scal...

The primary objective of pelleting is to produce a palatable, high quality product with minimum production expense. Manipulation of the feed pellets during the storage, transporting, and transfer to feeding lots seriously reduces the number of feed pellets that finally reach the feed pans. It seems that the best solution for this problem is to increase the Pellet Durability Index (PDI) of the f...
