Influence of various commercial dietary salts as a mineral source supplementation on performance of broiler

The present study was carried out at SAU- Tandojam during, 2013 where, one hundred twenty (120) day-old Hubbard broiler were kept under study and divided in four groups (A, B, C and D). The treatments were: common salt (CS), rock salt (RS) and black salt (BS) at the rate of 0.3 percent while, the group A was kept as control without addition of salts supplementation. The feed intake was recorded (3700, 3644, 3560 and 3610) g/bird with water intake (7545, 8080, 8120 and 7880) ml/bird and an average live body weight was noted (1680, 1800, 1850 and 1750) g/bird in different groups as; A, B, C and D, respectively. The feed conversation ratio was also recorded (2.20, 2.02, 1.92 and 2.06) and the carcass weight (975, 1080, 1140 and 1030) g/bird whereas, the dressing percentage (58.03, 60.00, 61.62 and 58.85) was recorded in sequenced groups. The heart, liver, gizzard, crop, spleen, intestine and proventriculus weight was found to be non significant in respective groups. Simultaneously, the mortality ratio was observed in which, the higher was found (10.00%) in group-A (control) and the lowest (3.33%) in group-C. Finally, economics of broiler was calculated and net profit (Rs. 13.90, 29.93, 34.48 and 12.16) per bird was taken in sequenced groups. These figures indicated that the birds in group C fed on mash ration contained (0.3%) rock salt had remarkably higher net profit (Rs. 34.48) as compared to broiler in other treated groups. The analysis of variance of feed and water intake, live body weight and carcass weight results found the significantly different (P<0.05) whereas, the net profit in group C remarkably higher.
