The effect of feeding 75% fermented urea plus (+) methionine treated sorghum beer residue (RSBR) diets supplemented with and without enzymes (Nutriad® (+N), Zymos-N® (+Z) and Fullzyme® (+F) in broiler chicks starter diets were investigated. A total of three hundred and forty five (345) day-old broiler chicks were randomly assign to five (5) dietary treatments with three (3) replicates (15 pens), each consisting of twenty three (23) birds in a completely randomised design. The dietary treatments were formulated to be iso-nitrogenous and iso-caloric such that diets 1 (control), 2, 3, 4, and 5 contained 0% RSBR, 75% RSBR, 75% RSBR + N, 75% RSBR +Z and 75% RSBR +F respectively. The starter period lasted for twenty eight (28) days. The daily feed intake and weight gain of birds on diets +N and +Z were similar but significantly higher (p<0.05) than those on control, 2 and 5 (+F) diets. The feed to weight gain ratio were similar (p>0.05) for birds on all supplemented diets but significantly lower compared to birds on control. No mortality was observed with birds on +N and +Z diets during the starter period compared to birds on other diets. Economically, it was more profitable to use 75% fermented urea plus (+) methionine treated sorghum beer residue supplemented with specific enzymes in broiler chicks starter diets than the control and the un-supplemented diets.
From the findings, it can be concluded that starter diets containing 75% fermented itrogen plus sulphur treated sorghum beer residue supplemented with enzymes (Nutriad, Zymos-N or Fullzyme) enhances better performance of broiler birds during the starter period. This is reflected in improvement in feed intake, body weight gain, and lower feed cost per kg gain.
Also RSBRN+S supplemented with either of the enzymes replaces GNC up to 75% without adverse effects on growth performance.The use of 75% RSBRN+S with either Nutriad®, Zymos-N® or Fullzyme® enzyme supplementation in the starter diets of broiler chickens as a means of reducing pressure on conventional plant protein sources, like GNC and soya bean, is recommended. Similarly, The evaluation of the effect of feeding 100% RSBRRN+S diets supplemented with multienzyme on the performance of broiler starter chicks is recommended.
