Effects of Mesolites from Moghueieh Region and their Particles Size on Performance, Blood Biochemical Parameters and Nutrient Digestibility in Broiler Chickens

Abstract

In this study the effects of mesolites from Moghueieh region and their particles size on performance, blood biochemical parameters and nutrient digestibility in broiler chickens were evaluated. The experiment was conducted on a completely randomized design with three treatments: without mesolite (control) and with fine particle mesolite (passed of 1 mm sieve and stay in 0.225 mm sieve) or large particle mesolite (passed of 3.36 mm sieve and stay in 1.68 mm sieve). Mesolite added in amount of 2% in diet from 7 day of age. Results indicated that chickens fed large particle mesolite showed reduced performance and fine particle mesolite had no effect on broilers performance. When compared with the controls, body weight gains were significantly lower for birds fed diets containing large particle mesolite. Birds fed large particle mesolite showed higher feed conversion ratio. At the end of the experiment (42 day of age), control group had higher serum TG. Concentration of serum HDL in chickens fed large particle mesolite was higher than control group. Level of serum alkaline phosphatase, glucose, albumin, thyroxin, cholesterol, LDL and uric acid and digestibility of dry matter and protein were not affected by treatments.
