Abstract |
A study was conducted to evaluate the effects of manipulation of dietary
protein on the physico-chemical quality of broiler faeces and response
of these qualities to 1.5% alum (Aluminium sulphate) treatment during
storage. Chicks were allotted to corn-soy diets in a completely
randomized design for forty-two days. The diets were 22 and 20% CP with
methionine + lysine content balance and, 22 and 20% CP diets with 110%
NRC recommendation of methionine and lysine. Faecal nitrogen decreased
(P<0.05) with dietary protein levels and, methionine and lysine
supplementation of 22 and 20% dietary protein. Faecal pH of broiler fed
low protein diets were slightly acidic and ranged from 4.76-4.80. Faecal
minerals were generally lower than the range of values reported for
broilers in other investigations. Furthermore, treatment of broiler
faeces with alum (1.5%) led to reduction in pH (4.78 to 4.58). Also,
rate of reduction in faecal nitrogen and organic matter levels, and
increase in pH was observed to be lowering in alum-treated compared to
the untreated broiler faeces in a 7 days storage. In conclusion, feeding
low level of dietary protein with or without methionine and lysine
supplementation in excess of requirement is a suitable means of reducing
nitrogen and mineral excretion in broiler production. During feacal
storage, reduced nitrogen volatilization and consequently, nitrogenous
emissions from broiler faeces can be achieved by the addition of alum
treatment.
