| description | The experiment was conducted to evaluate the nutrients equivalency value of <em>Bacillus subtilis</em> spore (GalliPro<sup>®</sup>) for broiler chickens and its potential for decreasing feed nutrients concentration and cost. A total of 720 day old Ross 308 broiler chicks was allocated in 6 treatments (2 sexes×3 diets) with 6 replication for 7 weeks. Dietary treatments: main treatment (MT) was routine broiler diet added 0.2 g/kg GalliPro<sup>®</sup> (<em>Bacillus subtilis</em> 4×109 CFU/g DSM 17299) and using nutrients equivalency of GalliPro<sup>®</sup> for feed formulation; negative control (NC) was the same as main treatment without GalliPro<sup>®</sup> (subtracted the nutrients equivalent value of GalliPro<sup>®</sup>); positive control (PC) was the same as MT diet in nutrients content but without GalliPro<sup>®</sup>. Effect of dietary treatments on body weight (BW) was not significant. However, the average BW of male and female chicks receiving negative control diet was 2.0% (68 g) lower than PC and MT groups (P>0.05). Dietary treatments had no significant effect on average daily feed intake. Feed conversion ratio of chicks receiving PC and MT diets were 2.7% better than NC chicks (P<0.01). Male chicks were superior to female in all measured traits (P<0.01). Effect of treatments on carcass characteristics was not significant. There was no interaction between factors on measured parameters. Performance of chicks receiving diet with GalliPro<sup>®</sup> compared with PC showed that GalliPro<sup>®</sup> liberated 0.4 crude protein from MT diet and consequently decreased the broiler feeding cost. |
