“…As a consequence, improved dry matter intake, feed efficiency (Mir and Mir, 1994;Wallace, 1994), rumen propionic acid and total volatile fatty acids content (Arcos-Garcia et al, 2000;Miller-Webster et al, 2002), diet digestibility (Zeoula et al, 2008), and weight gain (Haddad and Goussous, 2005) may be achieved. Therefore, given that yeast culture may be useful at improving dietary energy utilization, it is reasonable to investigate its effects on meat production.…”

To evaluate the effects of the supplementation of feed additives on carcass quality in beef cattle, 72 Nellore steers (339.5kg, 20-month old) were feedlot finished and fed for 91 days one of the following diets: 1) control with no additives; or added of 2) live yeast culture; 3) monensin; or 4) the association of both additives. After slaughter, renal, pelvic, and inguinal fat and hot carcass weights were recorded and carcass was split into muscle, bone, and trimmable fat. Carcass Longissimus muscle area and subcutaneous fat thickness at the 12 th rib were measured and steaks of Longisimus muscle were taken to determine meat color, shear force, drip, and cooking losses. Yeast increased carcass dressing percentage but there were no effects on hot carcass weight, Longissimus area, subcutaneous fat thickness, percentage and weight of retail cut yield and trimmings. Feed additives had no effect on carcass pH, meat color, fat content, shear force, and drip losses. Supplementation of yeast, monensin or the association of both additives had no important effects on carcass traits and on meat quality of feedlot finished steers.Keywords: steer, direct-fed microbial, ionophores, retail product yield, shear force, Saccharomyces cerevisiae RESUMO Avaliaram

“…Similarly to our results, Williams et al (1991) found an increase of hay degradation after 12 h incubation as an effect of supplementing live cultures of Saccharomyces cerevisiae (Yea Sacc 1026 ). Differing effects were obtained by Arcos-Garcia et al (1999) who observed changes in dry matter degradation affected by the addition of live yeast cultures only after 48 h incubation (Levucell). The addition of yeast may increase the counts of cellulolytic bacteria (Harrison et al, 1988), and, as a consequence, improve fibre digestibility (Carro et al, 1992).…”

The aim of the study was to determine the effect of two live yeast cultures (LY1 and LY2) and yeast metabolites (YM) on dry matter degradability. Dry matter degradability of maize grain, cellulose and wheat straw was determined in vitro using a Daisy II incubator (ANKOM Technology). A statistically significant increase (P<0.05) was observed in dry matter degradation of maize grain after the application of yeast, although no such effect was seen on the degradation of wheat straw. After incubation of cellulose for 12 and 14 h , the highest increase in degradability was observed after application of LY2. Yeast metabolites (YM) significantly improved (P<0.05) the degradability of cellulose after 6 h incubation.

“…Data indicate that supplementation of yeast in the ruminant diet may improve feed intake, fiber digestion, numbers of anaerobic and cellulolytic bacteria, and ruminal pH value. It may also alter the composition of volatile fatty acids, reduce lactate accumulation and the concentration of oxygen in the rumen fluid, and improve utilization of starch 1,2 . Also, yeast cultures have biologically valuable proteins combined with high potency vitamin B-complex, important trace minerals and protein…”

“…Fadel Elseed and Abusamra 28 reported yeast supplementation increased OM digestibility by 10.1% and NDF digestibility by 10.5% for 5 g/day yeast supplementation in goat's kids ration. Arcos-Garcia et al 1 reported that forage quality may affect the response to yeast culture in NDF digestion, and that more benefits can be obtained with good quality roughages.…”

SummaryThis study was carried out in two experiments. Experiment 1 was conducted with six ruminally-cannulated one-year old Kangal Akkaraman male lambs, using a crossover design with 2 periods to determine the effects of live yeast culture supplementation on rumen fermentation. Yearlings were either supplemented with 4 g/d of Saccharomyces cerevisiae (BeneSacc, 4x10 9 CFU/g) or not supplemented (control). Animals were penned individually, and were fed a diet composed of 25% forage and 75% concentrate for sixteen days. Rumen fluid was sampled on day 16, 0 h (before feeding), 3 h and 6 h after feeding. Rumen pH, the numbers of protozoa, ammonia-N and volatile fatty acids (VFA) were determined in samples. Molar proportions of acetate were decreased, and propionate was increased with supplementation of live yeast culture. No differences were observed for ruminal pH, protozoa population, total VFA and ammonia-N concentrations, between treatments. In Experiment 2, in situ nutrient degradability of barley grain, corn dried distillers grains with solubles (DDGS) and wheat straw were determined. Live yeast culture supplementation did not affect dry matter (DM) degradability of barley, DDGS or straw, crude protein (CP) degradability of DDGS, nor neutral detergent fiber (NDF) degradability of straw. But, it reduced the potential degradability of DDGS in rumen..

Deneme 1, canlı maya kültürü ilavesinin rumen fermentasyonu üzerine etkilerini tespit etmek için, rumen kanülü yerleştirilmiş 6 baş bir yaşlı Kangal Akkaraman erkek toklu ile çapraz deney düzenine göre iki dönem halinde yürütüldü. Grubun biri kontrol olarak tutulurken, diğerinin yemlerine günlük 4 g Saccharomyces cerevisiae içeren canlı maya (BeneSacc, KOB=4x10 9 ) kültürü ilave edildi. Hayvanlar bireysel bölmelerde tutuldu ve %25'i yonca, %75'i kesif yemden oluşan rasyonlarla 16 gün süreyle beslendi. 16. günde hayvanlardan yemleme öncesi, yemlemeden 3 ve 6 saat sonra rumen sıvısı örnekleri alındı. Örneklerde pH, protozoon sayısı, amonyak N'u ve uçucu yağ asitleri (UYA) belirlendi. Canlı maya kültürünün ilavesi ile asetik asit oranı azaldı, propiyonik asit oranı arttı. Ruminal pH, protozoon konsantrasyonu, toplam UYA'leri ve amonyak N'u, bakımından muameleler arasında farklılık gözlenmedi. İkinci denemede; arpa, kurutulmuş mısır damıtma ürünü (KMDÜ) ve samanın in situ besin madde yıkılabilirlikleri tespit edildi. Canlı maya kültürü ilavesi arpa, KMDÜ, samanın KM yıkılabilirliğini, KMDÜ'nün ham protein, samanın NDF yıkılabilirliğini etkilemedi. Fakat KMDÜ'nün rumende potansiyel yıkılabilirliğini düşürdü.
