Effects of Using Safflower Meal on Performance and Quality and Quantity Characteristics of Egg in Laying Hens Ali Ehsani a ehsani63@yahoo com February 27 2012 Department of Animal Science College of Agriculture Isfahan University of Technology Isfahan 84156 83111 IranDegree M Sc Language FarsiAmir Hossein Mahdavi mahdavi@cc iut ac irAbdolhosein Samie asamie48@cc iut ac irAbstractOne of the major problems facing poultry nutrition in Iran is large fluctuation in market price of proteinresources In order to reduce feeding costs attempts have been made to use agricultural and industrialbyproducts as feed ingredients In line with this strategy this study was conducted to evaluate the effects ofenzyme supplementation of safflower meal included diets on productive performance egg qualitycharacteristics and some blood parameters of laying hens A total of 250 white leghorn hens Hy Line W 36strain were divided in 50 cages n 5 Based on a 5 2 factorial arrangement of treatments ten isocaloric andisonitrogenous diets ME 2750 Kcal Kg and CP 14 61 g Kg including 5 levels of safflower meal 0 0 25 0 50 0 75 0 and 100 0 g kg 1 with and without enzyme Bergazym P 0 0 and 1 0 g kg 1 wereassigned to hens in 5 cages replicates During the 10 weeks of experimental period eggs were collected andweighed daily and feed consumption was weekly recorded After 48 and 55 days of experiment birds wereinjected with 1 mL of 7 Sheep Red Blood Cells SRBC intramuscularly At the end of experiment theantibody titer against SRBC and differential circulating leukocyte count were measured for investigating ofimmune status Data was analyzed based on completely randomized design using GLM procedure of SAS Dietary inclusion of safflower meal and enzyme supplementation had no significant effect on egg qualitytraits However the performance was improved in the hens fed on safflower meal diets as well as enzyme supplemented diets Birds received dietary inclusion of safflower meal have higher egg production significantly P 0 05 Dietary safflower meal inclusion improved egg production of hens in the levels of 2 5and 5 P 0 05 during weeks 7 till 8 however this parameter was not affected during the all experimentalperiod 1 10 Hens fed safflower meal diets improved feed conversion ratio in the levels of 0 0 2 5 and 5 however the reverse trend was found in the levels of 7 5 and 10 Using safflower meal diets increased feedintake during the all experimental period slightly P 0 095 Also enzyme supplementation improved thefeed conversion ratio during the experiment P 0 11 Antibody titer against SRBC was not affected bytreatment however dissipation count of white blood cells was affected markedly P 0 05 Therefore ourresults indicated that safflower meal can be included in diets of laying hens up to 5 with no adverse effecton performance Also administration of cocktail commercial enzyme to the diets of laying hens would havebeneficial effect on performance especially in terms of egg production and feed conversion ratio Key words Safflower meal enzyme laying hens performance blood parameters
