“…Supplementation of yeast cell wall products in animal feed has been reported as a potential alternative to antimicrobial growth promotors (Hashim et al 2013;Fowler et al 2015a). Yeast cell wall is capable of changing the microflora community structure in the gastrointestinal tract and changing the histological structure of the gut mucosa (Reisinger et al 2012;M'Sadeq et al 2015).…”

Different supplements or strategies have been proposed as alternatives to the use of antibiotics at sub‐therapeutic levels in chickens. Mannan oligosaccharides and β‐glucans, yeast cell wall fractions (YCW), have been reported to beneficially influence broiler performance and health. Two differently produced yeast cell wall fractions derived from Saccharomyces cerevisiae were evaluated in this study using two different supplementation strategies offered to full‐term broilers. The birds were placed in floor pens on used pine‐shaving litter to increase potential microbial stress and mimic industry practice. The study utilized a three‐phase feeding program with a 1‐ to 21‐day starter, 21‐ to 35‐day grower and 35‐ to 42‐day finisher phases. Five dietary treatments were compared in this study. The experimental diets consisted of a control basal broiler diet; or the basal diet supplemented with the two differently produced fractions of YCW. The YCW products were supplemented at a constant 250 ppm or a decreasing concentration program (500, 250, 125 ppm) throughout the three feeding phases. Birds fed diets supplemented with either YCW products at any inclusion regimen demonstrated higher (P < 0.05) body weight (BW) in all three phases than control birds. The difference in final 42‐day BW of the YCW treatments (3041 g) averaged 165 g higher (P < 0.05) than the control group. For all YCW treatments, productivity index was higher (P < 0.05) in the grower (418) and finisher phase (441) versus control birds (389 grower and 415 finisher). These results suggested that both YCW fractions prepared from Saccharomyces cerevisiae can improve broiler performance when added at either a constant rate (250 ppm) or at a decreasing rate from 500 ppm for the starter to 125 ppm for the finisher phase.

“…Da mesma forma, Gurbuz et al (2011) constataram que a suplementação de 50 g/t de parede celular de levedura aumentou a produção de ovos, consumo de ração e o peso das aves, mas não verificaram efeito sobre o peso do ovo, taxa de mortalidade e da conversão alimentar. Já o uso de mananoligossacarídeos (1.000 g/t) de acordo com Çabuk et al (2006) efeitos benéficos sobre a casca dos ovos com o uso de mananoligossacarídeos, porém os mecanismos envolvidos ainda não são bem conhecidos (BOZKURT et al, 2012b;HASHIM et al, 2013). As altas temperaturas são conhecidas por afetar a qualidade da casca dos ovos, Bozkurt et al (2012a) (SILVA & NÖRNBERG, 2003).…”

Yeast culture ( YC ) positively affects the performance of laying hens. The purpose of the present study was to explore the underlying mechanism for the YC-mediated performance improvement. Sixty 67-week-old Hy-Line Brown laying hens were randomly allocated into 2 experimental groups with 5 replicates of 6 birds each. One group was fed a control diet, whereas the other received the control diet supplemented with YC at 3.0 g/kg; treatment lasted for 8 wk. The results showed that dietary YC supplementation increased ( P < 0.05) the total egg weight (11.2–13.6%) and egg-laying rate (13.0–13.5%) but decreased ( P < 0.05) the feed/egg ratio by 9.3 to 11.0% during weeks 5 to 6 and 7 to 8 compared with the control. However, egg quality, including eggshell strength, eggshell thickness, egg weight, albumen height, egg yolk color, and Haugh unit, was not affected ( P > 0.05) by YC supplementation. Furthermore, dietary YC supplementation increased ( P < 0.05) chymotrypsin and ɑ-amylase activities by 54.8 to 62.5% in the duodenal chyme and reduced ( P < 0.05) plasma endotoxin by 44.1%. YC dietary supplementation also upregulated ( P < 0.05) the mRNA levels of intestinal barrier–related genes (occludin and claudin 1) and antimicrobial peptides genes (β-defensin 1 and 7 and cathelicidin 1 and 3) in the duodenum or jejunum compared with the control. In conclusion, dietary YC supplementation improved the performance of aged laying hens, potentially through the upregulation of intestinal digestive enzyme activities and intestinal health-related gene expression.
