• Transferred into eggs, milk …

• Decrease quality of food ( changes in lipid profiles, antioxidant

concentrations…)

• Affect blood composition

MTX+ in Hatchery

• Reference with MT.x+ used in our farm.

• It’s very please to say you that MT.x+ done very good job for saving our economical losses in breeders.

• We have got nice results :

MTX+ in Hatchery

•We observed that wrinkle eggs and

shell-less eggs come down

• Our hatchery eggs percentage also

improved by 2.3%.

MTX+ in Hatchery

• In hatchability percentage : we improved our hatchability up to 2%

• We save cull percentage by 1.5% where as standard 2.0%.

• Cumulative hatchery performance

improved by 3.5%.
