Abstract
The nutritive value of brewers' spent grains (BSG) and two commercial
poultry feeds produced try Arewa and Pfizer companies and the effect of
feeding sodium metabisulphite-treated (1%) feed to day-old pullets have
been investigated.
The feed mashes were found to contain inadequate levels of a number
of amino acids some of which are essential for birds.
The BSG was found to be fairly rich in essential amino acids but it
alone could not support the growth of s t a r t e r pullets while 25% BSG
added to Pfizer chick mash when fed to starter pullets, resulted in
significant (P < 0.05) growth retardation and increased mortality r a t e.
However, a similar addition to Pfizer growers mash had no detrimental
effect on the chicks.
Addition of sodium metabisulphite to the wet BSG (3,000 ppm)
enhanced the keeping quality of the BSG.
Feeding day-old pullets with Arewa diet containing 1% sodium me tabisulphite
for 8 weeks did not have any significant effect on d i g e s t i b i l i t y and feed
consumption but resulted in gradual growth retardation without abnormal
histological changes in the liver, kidneys and spleen.
Blending the grain size of Arewa feed to fine particles resulted
in a marked retardation in growth of and the amount of the feed
consumed by the day-old chicks.
