Meta Analysis to Draw the Appropriate Regimen of Enzyme and Probiotic Supplementation to Pigs and Chicken Diets

Abstract

Along with the recent changes in animal feed supply circumstances, many enzyme and probiotic feed supplements have been introduced and applied to pigs and chicken diets. Therefore, both selection of the appropriate feed supplements and their proper supplementation becomes critical to justify the supplementation. Meta-analysis was proposed as an appropriate tool to assess the large amount of relevant information. In this review, reliable data from recent publications was compounded then analyzed to determine the best practice of effective enzyme supplementation from the perspectives of animal species, age, characteristics of feed, target substrates, optimum multi enzymes combination and intended objectives. The results of the analysis suggested pratical methods of probiotic supplementation regarding intestinal microbiota, physiological limitation of probiotics, maximization of the probiotic benefit and synergism with prebiotic supplements.

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

“…Today, addition of probiotic in diet is a common strategy for animal nutrition, because probiotic is a natural growth promoter instead of feed antibiotic (Rekiel et al 2007). Adding probiotic in the diet improves the animal immune system and the host's resistance to enteric pathogens, affects intestinal morphology as well as intestinal function, feed conversion, weight gain and performance of birds (Dalloul et al 2003, Chichlowski et al 2007, Vila et al 2009, Ohh 2011. Li et al (2006) also reported that addition of Bacillus subtilis culture to the layer diet decreased cholesterol concentration in egg yolk.…”

A β‐mannanase from Paenibacillus sp.: Optimization of production and its possible prebiotic potential

“…The prebiotic nature of MOS has been demonstrated previously and has also been revealed to have a positive effect on gut motility [21,32]. Although there were few reports on oligosaccharide production from KGM [33] and CM, and copra mannan hydrolysates were used for prebiotic analysis, resulting in 0.09-2.15 log cfu/mL enhancing activity [34], but no report was available with LBG, GG, WB, and OB.…”

“…5). The results in the been reported to reduce incidence of pathogens in animals [8,32]. Yet, few studies have investigated MOS as prebiotic to check their inhibitory effect.…”

Effects of Phytase Transgenic Corn on Growth Performance and Calcium and Phosphorus Utilization in Broilers

“…The efficacy of PTC was affected by the age of the broilers. Since the young broiler gastrointestinal tract is unable to secrete sufficient amounts of pepsin and gastric acid, this could explain why phytase was more efficient with more mature broilers (Ohh, 2011). It is concluded that partly replacing non-genetically modified corn with PTC can fully keep good growth performance despite halving the amount of diacalcium phosphate in the diet.…”
