Four diets were formulated with partial substitution (weight for weight) of maize with CWCC. Diet 1 contained no test ingredient (CWCC) and served as the control.
All ingredients except maize and cooked wild cocoyam [Colocasia esculenta (L.) Schott] corms (CWCC) that was substituted for maize were the same for all four diets.
A similar trend was obtained for the cost per kg feed such that the control diet (0% CWCC) was the highest (N50.01) which significantly (P < 0.05) decreased to N38.42, N36.84 and N35.26, for diets formulated with 10, 20 and 30% CWCC, respectively.
Results of the study revealed that LWand DW reduced as dietary inclusion level of CWCC increased.
Results of the blood chemistry evaluation of broiler finishers as affected by contents of anti-nutritional factors in CWCC arepresented in Table 6.
The determined nutrients composition reflected the variability in the original contents of maize and CWCC which were the variable ingredients.
The non-significant variation in feed intake across the dietary treatments was a result of minimal anti-nutritional factors (ANFs) in CWCC due to processing.
Reduced packed cell volume, haemoglobin and total protein have been linked to low levels of nutrients in feeds .That the birds fed the control diet had the highest cholesterol and subsequent reductions in serum levels of this parameter with increased inclusion level of CWCC may be linked to contents of saponins in the CWCC-based diets.
The objective of the meeting was increasing cooperation between the CWCC and the local manufacturers,in addition to increasing cooperation and coordination among them as well, in order to achieve complete domestication of the technology and industrial processes involved and thereby increasing investment opportunities in the sector.
The Deputy Governor of CWCC, Eng.Thabit Bin Suwaider Al Lehaibi said that some of the local industrialists have already started the process of initially manufacturing the membranes used in the reverse osmosis process,as well as some of the chemicals used in desalination processes.
