Abstract

This study was conducted on a private farm in Nagiup Mahfouz, Housh Isaa, Al-Beheira, Egypt, from March to April 2023, to examine the impact of a diet supplemented with algae (Spirulina platensis, Chlorella vulgaris, or their combination) on growth performance, carcass characteristics, meat composition, fatty acid content, certain serum biochemical parameters, histomorphological intestinal measurements, European productive efficiency, and economic efficiency under experimental conditions.
This study involved a total of four hundred and twenty unsexed, one-day-old Ross (308) broiler chicks, which were randomly allocated into seven dietary treatment groups, each group having a comparable average body weight of 42g.  Each group was represented by three replicates of 20 chicks each, maintained under similar management conditions.  Basal stander, grower, and finisher diets were supplemented with or without feed additives (two types of algae, SP, as, Spirulina and CV, Chlorella) as, T1, basal diet without supplementation (control), T2 and T3 fed a basal diet with 1g and 2g SP/ Kg diet at respective, T4 and T5 were chicks fed the basal diet with 1g and 2g CV/ Kg diet, T6 was fed a basal diet with 0.5g SP + 0.5g CV/ Kg diet and T7 was fed a basal diet with mixture algae 1g SP + 1g CV/ Kg diet of broiler chicks, respectively.
