Effect ofBacillus SubtilisSpore (GalliPro^®) Nutrients Equivalency Value on Broiler Chicken Performance

Abstract

The experiment was conducted to evaluate the nutrients equivalency value of Bacillus subtilis spore (GalliPro ® ) 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 ® (Bacillus subtilis 4×10 9 CFU/g DSM 17299) and using nutrients equivalency of GalliPro ® for feed formulation; negative control (NC) was the same as main treatment without GalliPro ® (subtracted the nutrients equivalent value of GalliPro ® ); positive control (PC) was the same as MT diet in nutrients content but without GalliPro ® . 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 ® compared with PC showed that GalliPro ® liberated 0.4 crude protein from MT diet and consequently decreased the broiler feeding cost.

Hematological parameters and selected intestinal microbiota populations in the Indonesian indigenous crossbred chickens fed basal diet supplemented with multi-strain probiotic preparation in combination with vitamins and minerals

“…It was apparent in the present study that dietary treatments did not produce any effect on carcass traits of the Indonesian indigenous crossbred chickens. Concomitant to our finding, treatment with either AGP [ 12 , 16 ], commercial B. subtilis [ 43 ] or multi-strain probiotic preparation in combination with vitamins and minerals [ 11 , 12 ] had no impact on the carcass traits of broiler chicks. Different from the above-mentioned studies, Shabani et al .…”

Comparison of two probiotic preparations on growth performance, intestinal microbiota, nutrient digestibility and cytokine gene expression in broiler chickens

“…In addition, some researchers have reported that probiotics increased enzyme secretion from pancreas and intestinal mucosa (Chen et al 2009). On the other hand, it was reported that using B. subtilis spore (GalliPro®) at 0.2 g/kg as a feed additive reduced broilers' requirements of amino acids, CP, and consequently their feed cost (Zaghari et al 2015).…”

Growth performance, fatty acid profile and lipid oxidative stability of breast muscle in chickens fed probiotics and antibiotics or their mixture

“…Birds fed probiotics alone (Diet 3) and probiotic-antibiotic mix (Diet 4) had lower (P <0.05) feed conversion ratio than other treatments. Similarly, Zaghari et al (2015) reported that Bacillus subtilis strain (GalliPro) supplementation reduced feed intake and improved feed conversion ratio with no effect on weight gain throughout the trial, indicating that the probiotic exerted some beneficial effect on broilers. The superiority of the feed conversion ratio observed in birds fed Diets 3 and 4 corroborates the findings of Khaksefidi & Rahimi (2005), Biggs et al (2007) and Taherpour et al (2009), in which probiotic administration decreased feed conversion ratio in broilers.…”
