In general, weight gain was lower and feed conversion ratio higher in all groups of birds including the controls as compared to the suggestions of Hubbard [20].
Feed conversion ratio was found similar in all levels which is not significantly different (P> 0.05).
The following data were collected from each of 25 randomly selected broiler farms: feed conversion ratio, production index, viability ratio, monthly medicine fee (MMF), and monthly disinfectant fee (MDF).
Feed consumed was recorded daily, the uneaten discarded, and feed conversion ratio (FCR) was calculated (total feed : total gain).
The study seems to confirm that the feed containing the highest amount of blood meal gave the poorest performance in terms of growth and feed conversion ratio [14].
Several studies reported that, similar to the results of this study, there were no statistically significant differences among the groups based on feed conversion ratio in albino and normal pigmented rainbow trout (Oncorhynchus mykiss) polyculture (Degirmenci, 1998), brook (Salvelinus fontinalis) and rainbow trout (Oncorhynchus mykiss) polyculture (Okumus et al., 1999), rainbow trout (Oncorhynchus mykiss) and turbot (Psetta maxima) polyculture (Sirtkaya, 2013), and albino and normal pigmented rainbow trout (Oncorhynchus mykiss) polyculture (Yildirim et al., 2002).
Also, feed intake and dressing weight were positively affected as a result of feeding the CFE-supplemented diet but feed conversion ratio was not affected.
The piglets' weekly average body weight, average daily feed intake, average daily weight gain and average feed conversion ratio in different stages were analyzed to compare performance according to dietary lipid allocation and feeding regime.
The feeding rate significantly (p< 0.05) influenced the final fish weight, net weight gain (NWG), average daily growth (ADG), specific growth rate (SGR), and feed conversion ratio (FCR).
Results showed that body weight and feed conversion ratio (FCR) increased significantly (P<0.05) in T4 and T1 during fourth and third week, respectively.
The feed conversion ratio was calculated by dividing the amount of feed consumed in a certain period by the gain in weight at the same period (with consideration of dead birds), expressed in the same weight units.
