Abstract

ABSTRACT This study was conducted to investigate the effect of a commercial antioxidant (CAO; Rendox Plus®) treatment in stabilizing the poultry byproduct meal (PBPM) and then the subsequent effect of the treated PBPM on growth of broilers. Five batches A, B, C, D and E of PBPM were treated with CAO at 0, 250, 500, 750 and 1000 mL/ton, respectively and stored for 42 days. Oxidative stability of PBPM was estimated on day 0 and then weekly using Peroxide Value and Thiobarbituric Acid tests. PBPMs treated with 750 &1000 mL/ton presented the least oxidation and were selected to be included in broiler diets. A total of 240 one-day-old non-sexed Hubbard broilers were randomly divided into two flocks of 120 birds each. Each flock was further divided into four groups with three replicates of 10 birds each. The selected PBPMs (D and E) were added at 4%, 5%, 6% and 7% in the starter and grower diets. The experiment lasted for 35 days. The PBPM treated with 1000 mLCAO/ton exhibited the lowest (p 0.05) broiler feed intake, weight gain, feed conversion ratio, final body weight, carcass traits, or mortality rate. It was concluded that CAO was effective in stabilizing PBPM, and up to 7% (70 g/kg) of CAO-treated PBPM can be safely included in broiler diets without any harmful effect on their performance.

Highlights

The cost of feed ingredients is increasing day by day due to their shortage
On storage day 42, higher peroxide values (POV) and thiobarbituric acid values (TBAV) (5.39 ± 0.01 mEq/kg and 3.20 ± 0.05mg MDA/ kg, respectively) were observed in the control batch (A) relative to the other batches B, C, D and E, and the lowest values (p
Similar findings have been reported by Pereira et al (1975), who indicated that the fat oxidation accelerated at high temperatures can be controlled by the addition of the same CAO evaluated in the present study

Summary

Introduction

Protein- and energy-rich ingredients of poultry feeds are the most expensive. Protein is supplied both from vegetable and animal sources, such as oilseed meals, legumes, abattoir waste, poultry byproduct meal (PBPM), and fish processing byproducts. Exploring and utilizing feed resources that have high protein value for poultry and cannot be consumed by humans is necessary. In this regard, the use of unconventional poultry feed sources may be a solution. Unconventional feed ingredients include synthetic singlecell proteins, different animal processing byproducts, such as poultry byproduct meal (PBPM), and insects (fly larvae). Poultry byproduct meal is called poultry byproducts, poultry offal meal, poultry meal, poultry offal, poultry viscera meal, poultry slaughterhouse waste, chicken offal, chicken byproduct meal, hen meal and spent heal meal (Heuze et al, 2015)
