Abstract:
An experiment was performed
to assess the potential of microbial phytase and Saccharomyces cervisiae
(Sc47) on improving the utilization of phytate P and subsequently on
broiler performance fed wheat-corn-soybean meal basal diet from 7 –
49 day of age. A 3x2x2 factorial arrangements of treatments were used:
3 levels of Sc47 (0.0, 0.1 and 0.2 % of diet); two levels of phytase
(0 and 800 U / kg of diet) and two levels of nonphytate P (50% and 100%
of NRC (1994) recommended). Each treatment contained 3 pens with 15
birds/pen. Measurements included body weight gain (BWG), feed conversion
ratio (FCR), serum parameters, Tibia ash, P and Ca retention. During
the experimental periods effects of Non phytate phosphorous (NPP) levels
on all measured parameters was significant (P< 0.01). Phytase inclusion
at 800 U/kg of diet induced improvement (P< 0.05) in BWG, FCR, tibia
ash, P and Ca retention and also increased concentration of serum P
and protein (p< 0.05). Inclusion phytase on the diet containing the 50%
NRC (1994) NPP resulted improvement on the utilization of phytate P
and Ca by increasing P and Ca retention which led to an increase in
toe ash content. The experiment demonstrated dietary supplementation
of Saccharomyces cervisiae had a positive influence on the bird`s
performance. However, significant improvement (P< 0.05) was observed
in BWG and FCR during starter phase in chickens fed the diets containing
Saccharomyces cervisiae. Maximum responses to live yeast achieved
when broiler chicks were fed diet with 100% NRC (1994) recommended available
phosphorous. In conclusion, the finding of this study suggested combination
of supplemental phytase and live yeast (Sc47) had some beneficial effects
on improving the nutritive value of broilers diets in particular in
the low level of NPP.
