Abstract

This study was conducted to evaluate the effects of different nutrient density on PERFORMANCE of Hy-line (W-36) LAYING HENs in late phase of laying. This experiment was conducted with two hundred and fifty six LAYING HENs from 73 to 83 weeks in a completely randomized design with 4 treatments and 4 replicates with 16 birds in each replicate. Experimental diets were isocaloric and included: diet with nutrients recommended by Hy-line company for commercial production of LAYING HENs in late phase of laying (control), diet with 5 percent lower level of nutrients than nutrients recommended, diet with 10 percent lower level of nutrients than nutrients recommended and diet with 15 percent lower level of nutrients than recommended for 10 weeks. The results of this experiment showed that the PERFORMANCE and EGG QUALITY in LAYING HENs did not affected by different experimental diets (P>0.05).The comparison of PERFORMANCE and EGG QUALITY among treatments showed that 15 percent reduction of nutrient level than recommended by Hy-line company levels for commercial production of LAYING HENs in late laying period not only had not any adverse effect on PERFORMANCE and EGG QUALITY of LAYING HENs but also in more circumstance have positive effects on PERFORMANCE and EGG QUALITY and can reduce the price of feed production per kg of egg. Based on the results of this experiment reduction of 15 percent nutrient level than nutrients recommended by Hy-line Company for LAYING HENs in late laying period (73 to 83 weeks) had not any adverse effect on PERFORMANCE and EGG QUALITY.
