ABSTRACT
A 35-day experiment was carried out in a completely randomized design to determine the
efficacy of two phytogenic feed additives as veritable alternatives to antibiotics using 320 dayold
unsexed commercial Ross 308 broiler chicks. The chicks were randomly divided into four
groups of 80 birds each and assigned to four isocaloric (12.60, 13.2 and 13.4 MJ/Kg AMEn) and
isonitrogenous (25.0, 22.5 and 20.07 % CP levels) diets designated as follows: diet 1- maizesoybean
based diet without additives (negative control), diet 2- maize-soybean based diet
containing 10% tylosin (positive control), diet 3-maize-soybean based diet containing
phytonutrient (product 1) and diet 4-maize-soybean based diet containing phytonutrient (product
2). Diet 2 contained 200g/ton of antibiotics, while diets 3 and 4 contained 1L/ton each of
phytogenic feed additives. Each treatment was replicated 8 times with 10 birds per replicate.
Birds had adlib access to feed and water. At 35th day of the experiment, 8 birds per treatment,
one from each replicate pens were randomly selected, electrically stunned at 70V and killed by
cervical dislocation for meat quality, carcass and organ weights determinations. The birds had
their left and right tibias removed for bone strength and mineral assessment. Eight birds per
treatment were also randomly selected and euthanized according to standard ethical procedures
and used for assessment of haematological parameters. Inclusion of phytogenic feed additives
(products 1 and 2) resulted in significant reduction (p
