ABSTRACT
In this experiment, the chloride analyses methods for testing mixing homogeneity and effects of diets of different homogeneity on broiler performance were investigated. Two hundred and forty day-old broiler chickens were used in three treatments with four replicates, each of 10 males and 10 females. The experiment was conducted in three feeding phases (starter 0-2, grower 3-5 and finisher 6th week of age) and terminated on day 42. According to the results of preliminary mixer evaluation based on values of salt analysis, it was estimated that 0.20, 0.59, and 3.75 min mixing times were required for CVs of >20, 20 to 10 and <10% of diet uniformity, respectively. Experimental feeds were produced considering these mixing times. Chloride analysis of samples was performed using titrimetric and Merckquant methods. The correlation between CVs of the titrimetric and Merckquant chloride test was statistically significant (r=0.92, P=0.0009). No significant differences were obtained among treatments for average liveweight gain, feed intake, feed conversion, mortality, carcass yield and abdominal fat pad percentage. However, CV of final BW was numerically reduced with increase in mixing time.
