“…The number of somatic cells was not influenced with the addition of CSFA in the diets, and the obtained average (3.32 log 10 cells/mL × 1000) is close to values of 3.26 log 10 cells/mL × 1000 reported by Ribeiro et al (2008) in goats. However, Gomes et al (2012) observed values of 2.84 and 3.07 log 10 cells/mL × 1000 in post peak periods and at the end of lactation, respectively, for multiparous Saanen goats. Although there is currently no legal limit of the number of somatic cell count for goat milk in Brazil (Brasil, 2000) the values observed are higher than the limit of 1,000,000 cells/mL (3.0 log 10 cell/mL × 1000) established by Food and Drug Administration in the United States of America.…”

“…In a study conducted where lactating Saanen goats received different roughage:concentrate proportions, Zambom et al (2005) observed a value of 1.05 for the FE, when the goats were provided with 60% oat hay, a value that is close to the obtained average. Gomes et al (2012) reported a FE of 1.63, while Mendes et al (2010) observed an average FEc of 1.26 for Saanen and Brown-Alpine goats, respectively, receiving corn silage. When roughage sources as the corn silage, that present a lower cell wall content and grains, are added to the ruminant diets, better conditions of rumen fermentation are promoted, which contributes to greater feed efficiency values, when compared to those results obtained with dry roughage such as the used oat hay.…”

According on the fat source included in the diets for goats, the milk production can be increased and milk fatty acid composition can be improved. This study was conducted to evaluate the inclusion of protected fat (CSFA - calcium salts of fatty acids) in the diets of lactating Saanen goats on milk production and composition. Five Saanen goats (63.23 ± 9.08 kg body weight and 105 ± 3 days of lactation) were distributed in a Latin square design (5 × 5) with five diets: control (without the addition of CSFA) and the other diets with: 6.25, 12.50, 18.75 and 25.0 g CSFA per kg dry matter (g/kg DM), respectively. Dry matter intake (DMI) and milk production (MP) were evaluated. Milk samples were collected to determine milk composition and fatty acid profile. Feed efficiency (FE) was estimated. The supplementation of CSFA up to 25 g/kg DM did not influence the DMI, MP and FE. Milk components production (g/d) was not influenced by the inclusion CSFA in the diet; however, there was a linear reduction of 0.87 g protein per kg of milk for each 1% CSFA included in the diet. The concentration of linolenic acid (18:3n-3) in milk was improved with a maximum point of 24 g of CSFA per kg DM. CSFA can be included in the diets of lactating Saanen goats up to 25 g/kg DM with no interference on DMI and MP.

“…Thus, based on these results, we analyzed the data by isolating the effect of the genetic group as a random effect in the model, such that it was possible to study the effect of yeast isolated. Lima, Alcalde, Gomes et al (2012) also found no significant difference in digestibilities when soybean meal was replaced by yeast in diets for goats. The behavior presented by NFC digestibility once more demonstrates the need to study the genetic variation of animals.…”

ABSTRACT. This study was performed in order to evaluate the effect of dried yeast from sugar cane when replacing soybean meal in dairy heifers' diets. Twenty-four heifers, with an initial body weight (BW) of 178 kg, were distributed in a completely randomized design. The treatments were four levels of inclusion of dried yeast from sugar cane replacing to soybean meal (0, 33, 67 and 100% on a dry matter (DM) basis). While there was no difference in DM, neutral detergent fiber (NDF), metabolizable energy or roughage intakes, the intakes of non-fiber carbohydrates and concentrate were increased. The crude protein intake decreased according to the dried yeast from sugar cane when replacing soybean meal. The digestibility coefficients of DM and NDF showed no difference. Replacement of soybean meal with dried yeast from sugar cane had no effect on performance, because average daily gain and body measurements studied were similar for all animals and inclusion levels. Soybean meal can be completely replaced with dried yeast from sugar cane in diets for growing dairy heifers without restrictions; this will not affect the intake, digestibility, physical development of animals or metabolization of protein compounds.Keywords: digestibility, intake, nitrogen balance, soybean meal.Desempenho de fêmeas leiteiras alimentadas com levedura seca de cana-de-açúcar RESUMO. Objetivou-se avaliar o efeito da levedura seca de cana-de-açúcar em substituição ao farelo de soja em dietas de novilhas leiteiras. Vinte e quatro novilhas leiteiras com peso médio inicial (BW) de 178 kg foram distribuídas em delineamento inteiramente casualizado. Os tratamentos foram níveis de inclusão de levedura seca de cana-de-açúcar em substituição ao farelo de soja (0, 33, 67 e 100% com base na matéria seca (MS)). Não houve diferença para a ingestão de MS, fibra em detergente neutro (FDN), energia metabolizável e volumoso; entretanto, houve aumento na ingestão de carboidratos não fibrosos e concentrados. A ingestão de proteína bruta diminuiu de acordo com o aumento do nível de levedura em substituição ao farelo de soja. Os coeficientes de digestibilidade da MS e FDN não foram alterados. A substituição do farelo de soja pela levedura não promoveu efeito sobre o desempenho, pois o ganho médio diário e as medidas corporais estudados foram os mesmos para todos os animais, em todos os níveis de inclusão. O farelo de soja pode ser completamente substituído por levedura seca de cana-de-açúcar em dietas para novilhas leiteiras em crescimento, pois não afeta consumo, digestibilidade, desenvolvimento físico dos animais e metabolismo de compostos proteicos.Palavras-chave: digestibilidade, consumo, balanço nitrogenado, farelo de soja.

-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 ...
