Effect of Probiotic Supplementation on the Performance of Broilers

Intermittent feeding programme and addition of <i>Bacillus subtilis</i> based probiotics to the diet of growing broiler chickens: Influence on growth, hepatic enzymes and serum lipid metabolites profile

“…The results of our experiment showed that intermittent-fed birds were able to adapt to the feeding strategy for improving feed conversion and nutrient requirements, because they had similar body weight gain with control birds from 22 days of age to the end of the study. In previous studies, researchers indicated that addition of probiotic can stimulate growth and improve feed conversion ratio in broilers (Onderci et al 2008, Bansal et al 2011. In this study, a BSP diet did not affect body weight gain and feed intake but improved birds feed conversion ratio (P<0.05) from 36 days of age to the end of the experiment.…”

Synergetic Effects of Multispecies Probiotic Supplementation on Certain Blood Parameters and Serum Biochemical Profile of Broiler Chickens

“…Probiotics have been shown to have many benefits to the host animal but the most substantial one is that probiotic additives neither has any residues in animal production nor exerts any antibiotic resistance by consumption (Alkhalf et al, 2010). Many other positive impacts of probiotic supplementation in poultry have been well documented, including, accelerate development of normal microflora in the newly hatched chicks and protecting them against enteropathic disorders (Timmerman et al, 2005;Bansal et al, 2011), improving production performance, such as, feed intake, feed conversion efficiency and weight gain (Cruywagen et al, 1996;Cavit, 2003;Lesmeister et al, 2004;Awad et al, 2009;Alkhalf et al, 2010). Furthermore, the most important effect that it exerts body's resistance to infectious diseases (Santos and Ferket, 2006) and help lowering of chick mortality (Dhama et al, 2008;Hatab et al, 2016).…”

Effect of Different Levels of Supplemental Yeast on Body Weight, Thyroid Hormone Metabolism and Lipid Profile of Broiler Chickens

“…Santin et al [52] showed that cell walls of Saccharomyces cerevisiae improve nutrient absorption from the intestinal mucosa and suggested that this factor may be responsible for the improvement in performance of broilers supplemented with Saccharomyces cerevisiae. Probiotics act by reducing feed conversion, resulting in an increase of daily live weight gain [6,38]. This is achieved through a natural, physiological way, improving digestion by balancing the resident gut microflora.…”
