Effects of Different Levels of Methionine and Lysine Inclusion in Lohmann Silver Layers Ration on Production, Quality, Fertility and Hatchability of Eggs

Tewahdo Teshome

This study was conducted to evaluate the effects of feeding of inclusion of different levels of methionine and lysine on egg production, quality, fertility and hatchability on subsequent performance of Lohmann silver layers in poultry farm of Debrezeit Agricultural research center. 360 laying hens and 54 cocks of mature Lohmann silver breeds of similar age and weight group were used for this study. The birds were randomly allocated into six treatment groups of 60 birds in each treatment with three replications consisting of 20 layers each and three cocks. The birds were kept in deep litter floor housing covered with teff straw litter material. The treatment rations were T1: Standard layers diet without Met or Lys, T2=0.6% Lys and 0.2% Met, T3=Only 0.7% Lys, T4=Only 0.3% Met, T5=0.7% Lys and 0.3% Met, T6=0.8% Lys and 0.4% Met.
