“…The results from the pooled analysis showed that ADG and FCR were significantly improved in birds receiving diets containing CBM588. The results from this meta‐analysis are similar to those reported for a study that used a quantitative meta‐analysis approach to evaluate the efficacy of probiotics in broilers (Blajman et al., ). In that study, the authors reported a mean difference of 0.611 g/bird (95% CI 0.499–0.822 g/bird) between birds receiving probiotics and those fed control diets based on the results from 48 fully randomized and controlled studies available in the literature, and a mean difference of −0.281 g feed/g weight (95% CI −0.404 to −0.571) for FCR based on the results from 46 studies (Blajman et al., ).…”

The objective of this study was to assess the effects of a probiotic strain Clostridium butyricumMIYAIRI 588 (CBM588) on broiler and weaned piglet health and zootechnical performance. Five field studies were carried out in broilers and five in weaned piglets under European feed additive guidelines. Each study followed a randomized blocked design with two treatments: Control (basal diet) and CBM588 supplemented groups. The zootechnical performance parameters selected were body weight, daily gain, feed intake and feed efficiency (feed:gain). Broilers fed diets with CBM588 gained significantly more weight (+2%, p < .001) and exhibited significantly better feed efficiency (-1.6%, p < .001) in comparison with Controls. Similarly, analysis of pooled data of weaned piglet trials showed that CBM588-fed piglets were significantly heavier than Controls (+2.6%, p = .014), exhibited significantly higher mean daily gain (+4.7%; p = .004), and significantly improved feed efficiency (-4.2%, p = .001). In addition to the zootechnical efficacy studies, the preventive effect of CBM588 on necrotic enteritis (NE) was assessed in a natural challenge model in broilers where CBM588 reduced the incidence and severity of NE lesions. These data indicate the potential of CBM588 to improve broiler and weaned piglet zootechnical performance, and to make a positive contribution to animal health.

“…The obtained results also revealed that the effect of BL on blood cholesterol levels depends on the level of OCM inclusion. The influence of probiotics in reducing the total cholesterol can be attributed to its role in breaking down the total lipids and bile acids to avoid the re-synthesis of cholesterol [24,33]. Similar results were obtained when chicks fed diets supplemented with different probiotic strains [3,41].…”

“…In this study, broilers' feed may elevate the body fat bulk, which may be the reason for the increasing abdominal fat level in broilers fed the control diet in comparison to OCM and/or BL. Probiotics are well known for their function in facilitating the gut absorption of essential nutrients to improve the growth and, accordingly, the general health status, which means reducing the accumulation of nutrients in the gut such as abdominal fat [33].…”

Olive cake meal (OCM) is characterized by its high nutritional value and is used as an alternative source of protein and fats in poultry diets. However, due to the high percentage of fiber in OCM, beneficial bacteria cells are used to improve the digestion rates. Therefore, the influence of OCM and Bacillus licheniformis (BL) on the growth, nutrient utilization, blood chemistry, and muscle fatty acid profile of broilers was exclusively examined in this study. Three hundred and sixty birds were randomly divided into six experimental groups (6 replicates/10 birds each): Control, OCM (2%), OCM (4%), BL, OCM (2%)/BL, and OCM (4%)/BL groups. Although feed intake was not meaningfully influenced by dietary treatments, weight gain was enhanced and feed conversion ratio was reduced (p < 0.05). The abdominal fat was lowered in broilers fed OCM (2%), OCM (4%), OCM (2%)/BL, and OCM (4%)/BL diets without a difference to those fed BL only (p < 0.05). Interestingly, blood total protein, albumin, Newcastle disease (ND) titer, and high-density lipoprotein (HDL) cholesterol were significantly increased, while total cholesterol was decreased by the mixture of OCM and BL (p < 0.05). Muscle oleic and linoleic acids, as well as vitamin E, increased significantly in broilers fed both OCM (4%) and BL, while linolenic acid increased in all groups except those fed BL and control diets (p < 0.05). Liver malondialdehyde (MDA) was decreased by feeding BL or both OCM at 2% or 4% and BL (p < 0.05). In conclusion, the inclusion of BL to OCM diets resulted in improved fat utilization and, accordingly, enhanced growth, nutrient utilization, and antioxidative response in broilers. Based on the obtained results, it is recommended to use BL to improve the nutritional value of OCM and to increase the feed utilization of OCM by broilers.

“…However, so far, there are no reported studies evaluating the effect of P. xylanexedens, as a probiotic feed additive, on the broiler growth performance. Previous meta-analysis results have showed that the BWG and FCR were improved in birds that received probiotics in compare to the basal diet without additives (10). Studies with inulin and lactulose also showed pronounced effect on broiler performance by selectively stimulating the beneficial microorganisms (11,14,33).…”

The effects of Paenibacillus xylanexedens, alone or in combination with inulin and lactulose were evaluated on growth performance and intestinal histomorphology of male broilers. A total of 168 one-day-old male broiler chickens were randomly allocated to 4 experimental groups as follows: C, basal diet (control; without supplementation); P, 1×10 9 cfu/kg-feed P. xylanexedens; IN, 1×10 9 cfu/kg-feed P. xylanexedens and 1% inulin; LAC, 1×10 9 cfu/kg-feed P. xylanexedens and 0.5% lactulose. Addition of P. xylanexedens and synbiotics significantly increased broiler body weight gain (P<0.001) and feed conversion ratio (P=0.023) from 1 to 21 day of age. Moreover, a significant increase in body weight gain was observed when birds were fed with synbiotic supplemented diets during the overall experimental period (P=0.013). The addition of probiotic and synbiotics increased (P=0.047) villus height in ileum on day 42. Our results indicate that P. xylanexedens can be used as a probiotic feed additive in broiler diets and can improve broiler performance and intestinal histomorphology. Broyler rasyonlarında probiyotik ve sinbiyotik kullanılmasının broyler performans ve bağırsak histomorfolojisi üzerine etkisiÖzet: Paenibacillus xylanexedens'in tek başına veya inulin veya laktuloz ile birlikte kullanılmasının erkek broylerlerin büyüme performansı ve bağırsak histomorfolojisi üzerine olan etkisi incelendi. Toplamda 168 adet günlük erkek civciv dört deneme grubuna ayrıldı: C, bazal rasyon (kontrol); P, 1×10 9 cfu/kg-yem P. xylanexedens; IN, 1×10 9 cfu/kg-yem P. xylanexedens ve %1 inulin; LAC, 1×10 9 cfu/kg-yem P. xylanexedens ve %0.5 laktuloz. P. xylanexedens ve sinbiyotik ilavesinin 1-21. günlerde broyler canlı ağırlık artışını (P<0.001) ve yemden yararlanma oranını (P=0.023) önemli düzeyde arttırdığı sonucuna varıldı. Tüm araştırma periyodu dikkate alındığında sinbiyotik ilavesinin canlı ağırlık artışını önemli ölçüde (P=0.013) etkilediği görüldü. Araştırmanın 42. gününde probiyotik ve sinbiyotik ilave edilen gruplarda ileum villus yüksekliğinin daha fazla olduğu tespit edildi (P=0.047). Sonuç olarak, P. xylanexedens'in broyler büyüme performansını ve bağırsak histomorfolojisini olumlu yönde etkilediği ve rasyonlarında probiyotik yem katkı maddesi olarak kullanılabileceği görüldü.
