Feed industries are seeking new ways to cope with increased raw material costs, and one approach is to apply enzymatic treatment in the production of feed ingredients from animal by-products. Keratinases, a group of proteases, are capable of hydrolyzing keratin-rich material and have been applied in the production of cost-effective feather by-products for use as feed and fertilizers. The curren...

In a completely randomized design (CRD) experiment with 6 treatments and 4 replicates per treatment, the effect of energy and protein dilution during 6-12 days of age was tested in broilers. Rice hull was used for dilution of energy and protein at levels of 0.05 (control), 10, 15, 20, 25 and 30 percent. The metabolizable energy and crude protein content of the experimental diets were 3089, 2780...

Recent interest in renewable energy production has exponentially increased the utilization of ethanol, a biofuel produced largely from corn in the United States. Increased production of ethanol has redistributed corn from livestock production to ethanol production. In 2002, 11% of the US corn crop was used in ethanol production; with the increase in production as much as 30% of US corn was bein...

two types of paddy combine harvester (head-feed and whole-crop) are commonly available in different widths in developed countries. the use of combine harvesters can greatly decrease labor costs and efficiency. combine harvesters have been introduced in several east asian countries (china, japan, south korea) to decrease costs, but their technical and economic performance has not yet been studie...

Two experiments were conducted to investigate the effect of dietary energy levels on the performance of Arian broiler chicks. Trial 1 was performed in summer and trial 2 in fall. Both experiments were accomplished in 5×2 factorial designs, involving 5 levels of dietary metabolizable energy and two sexes. Each of the 10 resulting treatments was replicated 4 and 3 times in trials 1 and 2, respect...

in the process of milk production, the highest cost relates to animal feed. based on reports provided by the experts, around seventy percent of dairy livestock costs included feed costs. in order to minimize the total price of livestock feed, according to the limits of feed sources in each region or season, and also the transportation and maintenance costs and ultimately milk price reduction, o...

Sustained price increases for traditional cereal grain and protein meal feed commodities have forced the pork industry to consider the dietary inclusion of alternative feedstuffs. Crop seed may serve as feedstuffs but their demand as feedstock for human food, biofuel, and bioindustrial products has increased. Together with these products, coproducts such as distillers dried grains with solubles...

 Contribution change of factor costs analysis may help managers in decision making and in adjusting to changes. Over the last two decades, production and enhancement of kutum fingerlings have increased in Iran, reaching to more than 229 million fingerlings by 2005, but declined to 187 million from 2005 to 2008. Over the years 2002-2006, a study of fingerling production costs for kutum fish was ...
