Abstract

The experiment conducted in the field of poultry of the animal production Department _agriculture college _Kirkuk University for the period 10/5/2018 until 8/8/2018. The period of the experiment was 90 days. Amid to study the effect of using two levels of different types of ginger (Indian, American, Spaniel and South of African ) upon the performance quality and sensory traits of the ISA BROWN layer egg. Randomly distributed 108 layers at 38 weeks age to 9experimental treatments with 6 replicates for each treatment and cage (dimension of the cage were( 45 x 30 x 37) cm replicate in clouded two layers The birds fed ad libitum by the nutritional treatments as: T1(control treatment ) free from ginger adding ,T2:adding 1% of Indian ginger, T3: adding 2% of Indian ginger,T4 :adding 1% of American ginger,T5: adding2% of American ginger,T6: adding 1% of Spaniel ginger, T7: adding 2% of Spaniel ginger, T8 :adding 1% of South of African ginger, T9 :adding 2% of South of African ginger, The satirical analysis results referred to significant( p≤0.05) im provement for the birds of the treatements (2,5,6,7 and 8 ) comparing with the birds of the control treatement about (11.34, 10.79, 11.34, 11.29 and 13.88) % for the treatements above respectively in the egg production ,while the eggs weight of the birds for theT5 were significantly bigger than T8 and T9 birds egg (60.97, 58.83 and 58.40 gms of the 5, 8 and 9 treatements respectively). Egg mass for the T5and T7 birds were significantly better than T1 and T9 birds. There were no significant differennces among treatements for egg gravity weight, egg shape index and shell thickness. Feed intake significantly( p<0.05) decreased for the T7, T8 and T9 birds than T1 birds. Significantly improved the conversion rati of feed, energy, protein and methionine for the birds of the T5, T6, T7, T8 and T9 by comparing with the T1 birds. There were no significant differences among treatements for the internal and sensory egg traits, the ages percent weight of the egg components and the percentages weight of the internal organs.
