Abstract
In this study, we have evaluated the effect of three multi-enzymes nutrient matrix values and compared the results with that fed barley and the corn diets without enzyme. In entire period, addition of all enzymes to the barley-based diet significantly (p 0.05). Litter moisture and water to feed ratio at 15, 25, and 33 days of age significantly decreased by addition of all enzymes (p < 0.05). In conclusion, considering nutrient matrix values for all used enzymes improved performance of broilers and can be used in formulating diets commercial broiler diets based on barley.
Highlights
Due to instability of the world corn prices, the producer's propensity to use the other types of cereals, such as barley, in broiler chickens diet has been rapidly increased during the last few years.Acta Scientiarum
Before formulating, all of the major dietary ingredients were analyzed for AMEn, amino acid (AA) profiles, crude protein (CP), crude fiber (CF), ether extract (EE) and macro mineral contents as described by Association of Official Analytical Chemists (AOAC, 2000)
Results of Water-feed ratio were supported with Shirzadi, Moravej, and Shivazad (2009), who showed that use of four enzymes decreased water intake of broilers fed barley without considering nutrient matrix value for these enzymes
Summary
Due to instability of the world corn prices, the producer's propensity to use the other types of cereals, such as barley, in broiler chickens diet has been rapidly increased during the last few years.Acta Scientiarum. There are large number of projects that have carried out to investigate the effects of enzyme supplementation on broiler performance only by adding enzyme over on top of diet without any consideration of matrix values for the enzyme (VukicVrajes & Wenk, 1995; Kiarie, Romero, & Ravindran, 2014; Ravindran, Tilman, Morel, Ravindran, & Coles, 2007) In this way enzyme will be added to poultry feed after formulation of diet. The nutrient matrix values for enzyme indicate the amount of nutrient that could be released when the enzyme is added to diet Documentation of such information has the potential to help the producers to add less protein and metabolizable energy (ME) in diet for poultry, to reduce the cost of required feed. The purpose of this experiment was to investigate the effect of using matrix values for three NSP-enzymes on broilers performance that fed barleybased diets and to compare these matrix values at similar energy and protein level of diet at same nutritional management
