Abstract
The present study was conducted in a private farm in Gharbia
Governorate, Egypt, during period from December 2017 to February 2018.
This study the effects of adding a probiotic (dry yeast or Aspergillus
awamori) as antioxidant agents to diets containing oxidized palm oil on the
productive performance of egg quality traits, some blood components,
economic efficiency and relative economic efficiency of Gimmizah laying
hens.
In this study, one hundred and eighty (180), 28 weeks old Gimmizah
laying hens were used in the experiment. Hens were distributed at random
into 6 similar treatment groups. Each treatment group was divided into 3
replicates of 10 layers each in a completely randomized design. Layers
were housed in individual cages. The first group was fed a basal diet
contains 16.41% crude protein, 2748 ME kcal/ kg diet (positive control,
T1). The second group was fed basal diet added with 2% oxidized dietary
palm oil supplementation (negative control T2). Other groups three and four
were fed negative control with 0.5% and 1% dry yeast (Saccharomyces
cervices T3 and T4), respectively. While, five and six group were fed the
negative control with 0.5% and 1% Aspergillus awamori T5 and T6,
respectively.
