Effects of Physical Sizes of Clinoptilolite on Protein Efficiency Ratio, Intestinal Morphology and Growth Indices of Broilers

摘要: A total of 448 Ross 308 seven-day old male broiler chicks were assigned to seven treatments with four replicates, each containing 16 chicks, determine effects physical sizes and rate dietary inclusion clinoptilolite. The fed diet clinoptilolite at 1.5% particle size 0.4-0.8 mm showed significantly higher body weight gain than the control group that did not receive (P<0.05). Adding dietcaused a significant improvement infeed conversion ratio during 22-42 7-42 days age(P<0.05). Broilers had lower feed other groups. Addition improved protein efficiency in periods 3% longer villus height duodenumand those jejunumthan Among different treatments, groupreceiving thegreatest crypt depth. In conclusion supplementation positive on performance intestinal morphology broilers.
