OBLAKOVA, M., N. BOZAKOVA, M. LALEV, I. YOTOVA and T. STOYANCHEV, 2004. Effect of type of floor on productivity in turkey broilers. Bulg. J. Agric. Sci., 10: 623-627
The productivity of 80 turkey broilers divided in 4 groups, each of 10 males and 10 females: 1st group - B.U.T.9 on grid floor; 2nd group - B.U.T.9 on deep bedding floor; 3rd group - St. Z. -1 on grid floor and 4th group - St.Z.-1 on deep bedding floor was studied. Direct effect of type of floor (grid floor and deep (soft) bedding floor) on productivity (live weight and feed intake per kg weight gain) in raising of turkey broilers of the B.U.T. -9 hybrids and St.Z-1 hybrid was examined. The live weight of the turkey broilers was monitored every 14 days until the 113th day, and feed intake per kg of weight gain was calculated at the end of the attending period. Significantly higher (P<0.01) live weight was found in the two hybrids at 113-day of age raised on grid floor compared to birds on the deep bedding floor. After the 57th day of age, a difference in the live weight of males from all groups, maintained until the end of the feeding period, was reliably established. It was also reliably established that the females of the B.U.T.- 9 hybrid raised on grid floor were heavier as compared to those on soft bedding. In both hybrids a lower feed intake per kg weight gain was reported in turkey broilers raised on the grid floor.
