“…This may be related to the high rate of rumen degradation of yeast (Fregadolli et al, 2001;Magalhães et al, 1999), which may promote greater availability of nutrients in the rumen (Messana et al, 2009).…”

-It was used 27 goat kids (18 ¾ Boer + ¼ Saanen and nine Saanen; 18.0 ± 1.60 kg) distributed in a completely randomized design with factorial arrangement to evaluate productive performance and the total digestibility of dry matter and nutrients in the rations. Diets were composed of soybean meal, soybean meal + dry yeast or dry yeast as protein source, oat hay, ground corn and vitamin-mineral mixture with mean composition of 2.50 Mcal of ME/kg DM and 17.0% of crude protein on average. Digestibility was determined using indigestible neutral detergent fiber as marker. Intakes of dry matter, organic matter, crude protein and total carbohydrates were not altered by rations. However, inclusion of dry yeast in the rations reduced ingestions of ether extract, neutral detergent fiber and acid detergent fiber. Within breed groups, the ¾ Boer + ¼ Saanen goat kids showed the highest intakes of dry matter and nutrients, as well as the best means of daily gain, feed conversion and days in feedlot. Digestibilities of dry matter, organic matter, crude protein and total carbohydrates were higer -and the digesbility of ether extract was lower -for animals fed rations with dry yeast. There were no differences in digestibility of neutral detergent fiber. Rations with dry yeast showed the highest values of total digestible nutrients. Dry yeast can be used as alternative protein source in rations for goat kids because it does not change animal performance and it does have higher nutritional value than soybean meal. ¾ Boer + ¼ Saanen kids show, in feedlots, better performance in growth and finishing phases when compared to Saanen kids.Key Words: digestibility, goats, intake, performance, Saccharomyces cerevisiae Levedura seca de cana-de-açúcar na alimentação de cabritos em crescimento e terminação RESUMO -Foram utilizados 27 cabritos (18 ¾ Boer + ¼ Saanen e 9 Saanen; 18,0 ± 1,60 kg) distribuídos em delineamento inteiramente casualizado com arranjo fatorial para avaliar o desempenho produtivo e a digestibilidade total da matéria seca e dos nutrientes das rações. As dietas foram compostas de farelo de soja, farelo de soja + levedura seca ou levedura seca como fonte de proteína, feno de aveia, milho moído e mistura vitamínico-mineral, com composição média de 2,50 Mcal de EM/kg de matéria seca e 17,0% de proteína bruta. A digestibilidade foi determinada utilizando-se fibra em detergente neutro indigestível como indicador. As ingestões de matéria seca, matéria orgânica, proteína bruta e carboidratos totais não foram influenciadas pelas rações. No entanto, a inclusão de levedura seca nas rações reduziu as ingestões de extrato etéreo, fibra em detergente neutro e fibra em detergente ácido. Dentro dos grupos raciais, os cabritos ¾ Boer + ¼ Saanen foram os que apresentaram maior ingestão de matéria seca e nutrientes, assim como melhores médias de ganho diário, conversão alimentar e dias em confinamento. A digestibilidade de matéria seca, matéria orgânica, proteína bruta e carboidratos totais foi maior -e a de extrato etéreo menor -no...

“…Messana et al, (2009) stated that dry yeast does not alter the intake pattern in cattle. However, Aguiar et al (2007) concluded that replacing corn and soybean meal by urea and dry yeast in the diet of sheep negatively affects the energy intake and animal performance.…”

“…Early experiments were performed to evaluate the use of dry yeast as dietary protein source in diets for broiler chicks (Generoso et al, 2008), pigs (Junqueira et al, 2008), cattle (Messana et al, 2009), sheep (Aguiar et al, 2007) and meat goats (Lima et al, 2011). However, data on dairy goats are not found.…”

-The effects of inactive dry yeast (Saccharomyces cerevisiae) from sugar cane were studied in 18 primiparus Saanen dairy goats (51.07±1.43) on dry matter intake and digestibility, milk production and quality. Animals were distributed in a completely randomized design during 90 days (from day 60 of milking). Diets were composed of soybean meal; soybean meal + dry yeast; or dry yeast, as protein sources, and ground corn, mineral supplement and corn silage (40%). Animals fed the dry yeast diet showed lower intake of dry matter (DM), organic matter (OM), crude protein, ether extract and neutral detergent fiber. Diets did not influence milk yield; however the milk production efficiency (kg of milk produced/kg of crude protein ingested) was better in goats fed the dry yeast diet. Acidity, somatic cell counts and milk urea nitrogen values were not affected by treatments. Animals fed the soybean + dry yeast diet had higher fat and total solids than those fed the dry yeast diet. The digestibility of DM, OM and total carbohydrate was lower for soybean only and soybean + dry yeast diets.Total digestible nutrients were higher for dry yeast and soy bean diets than soybean + dry yeast diet. Dry yeast from sugar cane is a good alternative protein source for feeding lactating dairy goats and can be recommended because it maintains the production performance.

“…Devido ao seu alto teor energético e seu valor nutricional, o caroço de algodão está entre os alimentos que mais se destacam na alimentação alternativa para a bovinocultura de leite, suas características nutricionais se assemelha aos alimentos concentrados (Tabela 4), isso em função a seu grande conteúdo de fibra efetiva, porem devido à presença de substancias como gossipol e aflatoxinas, seu uso na dieta desses animais pode ser inviabilizado (MESSANA et al, 2009). Vilela et al (1996), trabalhando com vacas 7/8 Holandês x Zebu após pico de lactação com produção média diária de 20 kg, alimentadas com silagem de milho associada a quatro rações concentradas contendo 10, 20 e 30% de Caroço de algodão, concluíram que o caroço de algodão pode ser usado até o nível de 30% na ração concentrada sem influir no consumo dos nutrientes ou na produção de leite.…”
