The objectives of this presentation are to evaluate and compare the environmental burdens of the two different concentrate feed supply systems to Japanese domestic livestock industry. Life-Cycle Assessment (LCA) method is used on the two systems such as the conventional system depending on US-imported corn and the proposed new system. Japanese domestic livestock industry could reduce 78,462 ton...

Bambara groundnut is an indigenous African vegetable grown mainly for human food and animal feed due to its high protein content. Different factors like varieties and origin can influence the chemical composition of Bambara groundnut cultivars. Therefore, the aims of this study are to produce defatted flour and protein concentrate from newly developed Bambara groundnut cultivars [Accessions No:...

Pre-ruminant calves were pair-fed a concentrate feed in either liquid form (LC) from a nipple bottle or in dry form (DC). We then studied the effects of these two forms of feed on body weight gain, feed utilization, digestibility, digestive enzyme secretion and volatile fatty acids in the rumen liquor. The live weight gain of calves receiving the liquid concentrate was depressed by 34 p. 100. T...

An experiment was conducted to study the effects of lamtoro (Leucaena leucocephala) leaf supplementation in fermented kumpai grass (Hymenachne amplexia calis) based rations on the productivity of Bali cattle. Variables measured were dry matter and organic matter intakes, nutrient digestibility (dry matter, organic matter, crude protein, and crude fiber), body weight gain, and feed efficiency. T...

There are several flow configurations for RO that allow the user to get the most out of the system. This paper will cover a few of the techniques used in RO design to optimize system performance. These techniques include the use of concentrate staging and concentrate recirculation to increase recovery, permeate staging to attain ultrapure standards of separation, and permate throttling and inte...

The potential of rapeseed protein concentrate as an alternative to fishmeal in diets for common carp (initial average weight 26.7±0.8 g) was evaluated. Triplicate groups of fish were fed isonitrogenous (40.4±0.2% crude protein) and isocaloric (21.4±0.1 kJ/g) experimental diets with 0%, 33%, 66%, or 100% replacement of fishmeal by rapeseed protein concentrate. At the end of the 56-day feeding pe...

There were no considerable up to date on the trace element requirements of commercial poultry in recent years in despite of the progress in their performance traits. One of the more prevalent problems in modern broiler production system which could be attributed to the trace mineral inadequacy is skeletal disorders. Zinc, is an essential trace element which acts as a co-factor in several metalo...

The new copper processing plant of the Sarcheshmeh copper complex consists of two parallel circuits. After a primary crushing, the ore is sent to a SAG mill, and the product is further ground in a ball mill. The overflow of the hydrocyclones is fed to a flotation circuit that contains 8 rougher tank cells (RCS130), 3 cleaner cells (RCS50), 5 scavenger cells (RCS50), and a flotation column (as r...
