“…This agrees with the results of LIMA et al (2012a), who reported that feeding dry yeast as a protein source to lactating goats reduced the ether extract intake compared with soybean meal. The explanation for Parturition order influenced (P<0.05) both prepartum and postpartum body weight, intake of dry matter, nutrients and total digestible nutrients, with multiparous goats showing the highest values (Table 3).…”

-The aim was to evaluate the replacement of soybean meal by inactive dry yeast (Saccharomyces cerevisiae) from sugar cane on nutritive value of diets for Saanen goats in the peripartum. Twenty-four Saanen goats (nine primiparous, 55.35 ± 4.55 kg and fifteen multiparous, 73.12 ± 8.51 kg) in prepartum and postpartum periods were distributed in a completely randomized design with a 3 × 2 (diet × parturition order) factorial arrangement. Diets were composed of soybean meal, soybean meal plus dry yeast or dry yeast as protein source, and other ingredients: ground corn, mineral supplement and limestone. The roughage source used was the whole plant corn silage (40% of the total diet). Diets were evaluated as dry matter intake and digestibility of nutrients. The diet with total dry yeast inclusion promoted a reduction on the ether extract intake (postpartum) and ether extract digestibility (prepartum and postpartum), due its lower ether extract content when compared to the other diets. Multiparous goats presented higher intakes for dry matter, nutrients and total digestible nutrients in both evaluated periods due their higher intake capacity. Primiparous goats in postpartum had better coefficients of digestibility for dry matter, organic matter, crude protein and total carbohydrates, and so a higher energetic value, attributed to total digestible nutrients compared to multiparous ones. Dry yeast can replace soybean meal with no changes on nutritive value of diets for Saanen goats.Keywords: Digestion. Intake. Protein source. Saccharomyces cerevisiae. VALOR NUTRITIVO DE DIETAS COM LEVEDURA SECA INATIVA PARA CABRAS SAANEN NO PERIPARTORESUMO -O objetivo foi avaliar a substituição do farelo de soja por levedura seca inativa (Saccharomyces cerevisiae) de cana-de-açúcar sobre o valor nutritivo de dietas para cabras Saanen no periparto. Vinte e quatro cabras Saanen (nove primíparas, 55,35 ± 4,55 kg e quinze multíparas, 73,12 ± 8,51 kg) durante os períodos pré-parto e pós-parto, foram distribuídas em delineamento inteiramente casualizado, com arranjo fatorial 3 × 2 (dieta × ordem de parto). As dietas foram compostas por farelo de soja, farelo de soja e levedura seca ou levedura seca como fonte de proteína e os demais ingredientes: milho moído, suplemento mineral e calcário. A fonte de volumoso utilizada foi a silagem de milho de planta inteira (40% da ração total). As dietas foram avaliadas quanto a ingestão de matéria seca e digestibilidade dos nutrientes. A dieta com inclusão total de levedura seca promoveu redução na ingestão de extrato etéreo (pós-parto) e na digestibilidade de extrato etéreo (pós-parto e pré-parto), devido ao seu menor teor de extrato etéreo quando comparada as demais dietas. As cabras multíparas apresentaram maiores ingestões de matéria seca, nutrientes e nutrientes digestíveis totais, em ambos os períodos avaliados, devido a sua maior capacidade de ingestão. As cabras primíparas em pós-parto apresentaram melhores coeficientes de digestibilidade para matéria seca, matéria orgânica, proteína bruta ...

“…Also, the replacement of soybean meal by dry yeast as protein source in ruminant nutrition have been showed variable responses on intake and digestibility of dry matter and nutrients (FREITAS et al, 2011;GOMES et al, 2012;LIMA et al, 2012a).…”

“…Thus, the values showed in this study ranging from 2.87 g/kg to 3.92 g/kg were similar to recent studies on lactating goats that showed DMI (g/kg BW) ranging from 2.93 g/kg to 4.50 g/kg (Fonseca et al, 2008;Serment et al, 2011) According to the NRC (2007), the intake of animals is based on a combination of factors, such as its energy requirement, characteristics of the feed, BW, and BW at maturity. Lima et al (2012) reported higher DMI for 2-yearold goats compared with 1-year-old goats. This difference was attributed to the different BW (10.69 kg) between the ages at the first kidding.…”

-Twenty-four Saanen goats, 15 multiparous and nine primiparous, were distributed in a completely randomised design in a factorial arrangement (3 diets × 2 parities). The treatments were soybean meal (SB), soybean + dry yeast (SBDY), or dry yeast (DY) as a protein source in the diet, and ground corn, mineral supplement, and corn silage (400 g/kg). The study was conducted to evaluate the nutritive value of diets containing inactive dry yeast as a protein source postpartum, postpeak, and during late lactation in dairy goats. To estimate the faecal excretion of indigestible material, neutral detergent fibre was used as an internal marker. The diets did not affect dry matter intake (DMI). However, DMI and nutrient intake were higher for multiparous goats compared with primiparous goats. The digestibility of dry matter and total digestible nutrients (TDN) were higher for primiparous goats in the postpartum period. In the postpeak and late lactation periods, there were no differences in digestibility of DM and nutrient between parities. The TDN was similar in the diets in the postpeak period and at lactation end. The goats fed the DY diet had lower urea nitrogen in blood. The use of inactive dry yeast to substitute soybean meal in diets for primiparous and multiparous lactating Saanen goats is a good alternative for maintaining the nutritional value of diets.

“…SCY products are widely used as dietary supplements to increase milk yield in ruminants [46][47][48][49][50][51][52][53][54][55][56][57][58] and to improve the reproductive performance of sows and growth of offspring [59][60][61][62][63][64][65]. These products include active SCY, inactive SCY (SCYS) and yeast cell wall products (YCWPs), such as beta-glucan, MOS or combined products.…”

Saccharomyces cerevisiae Yeast-Based Supplementation as a Galactagogue in Breastfeeding Women? A Review of Evidence from Animal and Human Studies

Perceived insufficient milk production (PIM) adversely affects breastfeeding duration. Women sometimes use galactagogues with the intent to increase breast milk production and support lactation. Saccharomyces cerevisiae yeast-based supplement (SCYS) is an inactive form of Saccharomyces cerevisiae yeast (SCY) either obtained from the fermentation process or grown on molasses. Anecdotal evidence suggests SCYS is a galactagogue. SCYS is promoted on the internet as a galactagogue in various forms and doses. Dietary supplementation with SCYS during gestation and lactation significantly increases milk yield in ruminants. No human study has evaluated efficacy of SCYS as a galactagogue. SCYS is rich in B vitamins, beta-glucan, mannan oligosaccharides and bioavailable chromium; these may impact breast milk production or composition, thus may alleviate PIM. The safety of taking SCYS during lactation is not well studied. Studies have reported contamination of SCYS with ochratoxin A (OTA) as well as minor side effects from SCYS. Studies are needed to evaluate the efficacy of SCYS on breast milk production and composition and to assess the safety of taking SCYS during lactation in humans.
