Effect of zinc-bearing zeolite clinoptilolite on growth performance, zinc accumulation, and gene expression of zinc transporters in broilers.
This study investigated Zn-bearing zeolite clinoptilolite (Zn-ZCP) as a Zn supplement on performance, organ or tissue development, Zn accumulation in tissues, and gene expression of Zn transporters in the duodenum of broilers. A total of 300 1-d-old Arbor Acres chickens were randomly allocated to 5 dietary treatments with 6 replicate cages of 10 birds per treatment for a 21-d feeding period. Th...
متن کاملEffects of clinoptilolite and modified clinoptilolite on the growth performance, intestinal microflora, and gut parameters of broilers.
The purpose of this study was to evaluate the effect of natural clinoptilolite (NCLI) and modified clinoptilolite (MCLI) on broiler performance, gut morphology, and its relation to gut circumstances. A total of two hundred forty 1-d-old male chicks were randomly assigned to 3 treatments, each of which comprised 8 pens of 10 chicks per pen. Birds in the control group were fed the basal diet, whe...
متن کاملEffects of dietary supplementation of mannan-oligosaccharide on virus shedding in avian influenza (H9N2) challenged broilers
Avian influenza (AI) is a highly contagious disease causing significant economic losses worldwide. The aim of this study is to evaluate the effect of mannan-oligosaccharide (MOS) on tracheal and cloacal virus shedding in AI challenged broilers and contamination of environment with H9N2. A total of 300 1-day-old-broiler chicks were randomly divided into 3 groups (A, B and C) and supplemented 0.2...
متن کاملSafety, Protective Immunity, and DIVA Capability of a Rough Mutant Salmonella Pullorum Vaccine Candidate in Broilers
Salmonella enterica subsp. enterica serovar Gallinarum biovar Pullorum (Salmonella Pullorum) is highly adapted to chickens causing an acute systemic disease that results in high mortality. Vaccination represents one approach for promoting animal health, food safety and reducing environmental persistence in Salmonella control. An important consideration is that Salmonella vaccination in poultry ...
متن کاملEffects of Physical Sizes of Clinoptilolite on Protein Efficiency Ratio, Intestinal Morphology and Growth Indices of Broilers
A total of 448 Ross 308 seven-day old male broiler chicks were assigned to seven treatments with four replicates, each containing 16 chicks, to determine effects of physical sizes and rate of dietary inclusion of clinoptilolite. The chicks fed diet containing clinoptilolite at 1.5% and particle size of 0.4-0.8 mm showed significantly higher body weight gain than the control group that did not r...
