for determination of grazing capacity, information of forage quality is essential which is influenced by various factors. the main objective of this research was investigation on effects of species, phenological stages, and life form on values of forage quality indices of six range species. species were two grasses (bromus tomentellus and dactylis glomerata), two forbs (ferula ovina and coronil...

this study was carried out to determine regression equations for prediction of apparent metabolizable energy corrected by nitrogen (amen) using 11 barley cultivar (valfajr, karon, bahman, aras, dasht, afzal, zarjo, kavir, reihani, makui and yousef) the seeds obtain from alborz province, iran. all of the cultivar were analyzed based on proximate analysis, starch, ndf and adf. result showed that ...

An experiment was conducted to study the effect of metabolizable energy (ME) and protein of Japanese quails diets on offspring performance and antibody production against sheep red blood cell (SRBC). A total of 432 Japanese quails (13 week-old) were divided into nine treatments. Each treatment comprised four replicates of twelve birds (9 female and 3 male). Nine diets including three levels of ...

Feed is the greatest single cost factor in pig production. In pig diets, energy accounts for the largest proportion of the cost. Therefore, it is critically important that the energy content of a diet is characterized in the best possible way. There are several systems available for the characterization of dietary energy. The most common ones digestible and metabolizable energy describe the ene...

The presence of microbial load and high fiber content in various non conventional feedstuffs limit their utilization in poultry feed. In the present study, the feedstuffs were treated with acidified sodium chlorite (ASC) and its impact on  the microbial load and metabolizable energy availability was assessed in  the chickens. The effect of supplementation of feed grade enzyme was also evaluated...

Energy utilization in broilers as influenced by supplementation of enzymes containing phytase or carbohydrase activities was investigated. Day-old male broilers (480) were allocated to four slaughter groups, thirty broilers in the initial slaughter group and 150 broilers in each of the final slaughter groups on days 7, 14 and 21. Broilers in each of the final slaughter groups were allocated to ...
