“…Butyric acid concentrations were unaffected (P = 0.57) by protein (Table 4), which agrees with other results obtained with straw-based diets (Fike et al 1995;Zorrilla-Rios et al 1991) but not with those obtained by Sunvold et al (1991) or Hunt et al (1989). Butyric acid concentrations were reduced (P = 0.01) in animals fed concentrates on alternate days (Table 4).…”

[467][468][469][470][471][472][473][474][475][476][477][478][479]. Five ruminally cannulated crossbred steers (474 ± 30 kg) were fed diets containing 70% barley straw and 30% concentrate in an unbalanced 5 × 5 Latin square design experiment to investigate the effects of frequency of feeding concentrate (daily, alternate days or every third day) with different dietary protein concentrations (7.9 and 11.5%) on ruminal liquid and particulate dilution rates, pH and metabolite concentrations. Dilution rates of cobalt-ethylene diamine tetraacetic acid (Co-EDTA) and chromium-mordanted fibre did not differ when low-and high-protein concentrates were fed. Supplemental protein increased (P < 0.05) mean ruminal ammonia concentrations (3.3 vs. 1.6 mM), but had no influence on ruminal concentrations of organic acids. Frequency of concentrate feeding had no influence on dilution rate of digesta markers, pH or on mean ruminal concentrations of ammonia, lactic acid, propionic acid, isobutyric acid, valeric acid and isovaleric acid. Mean concentrations of total volatile fatty acids, acetic acid and butyric acid were, however, reduced (P < 0.05) when steers were fed concentrates on alternate days. The reduced (P < 0.01) ruminal acetic:propionic acid ratios observed in steers fed concentrates on alternate days were consistent with reduced heat productions. Positive relationships (P < 0.05) were obtained between heat production of steers and ruminal concentrations of isobutyric and valeric acids. It was concluded that the low-protein diet did not provide sufficient protein to meet microbial requirements and that under controlled feeding conditions cattle can be fed concentrate on alternate days or every third day without the occurrence of lactic acidosis. Additional research is warranted to examine the relationships between reduced heat production of steers fed concentrates on alternate days and ruminal concentration and production of organic acids. expérience en carré latin 5 × 5 non équilibré qui devait préciser les effets de la fréquence à laquelle un concentré à teneur variable en protéines (7,9 et 11,5 %) était servi (tous les jours, un jour sur deux ou aux trois jours) sur les fluides, le taux de dilution des particules, le pH et la concentration des métabolites dans le rumen. Le taux de dilution du cobalt-EDTA et des fibres mordancées au chrome ne varie pas avec la teneur en protéines du concentré. Le supplément protéique accroît (P < 0,05) la concentration moyenne d'ammoniaque dans le rumen (3,3 c. 1,6 mM), mais n'influe pas sur la concentration des acides organiques. La fréquence à laquelle on sert le concentré n'agit pas sur le taux de dilution des marqueurs des digest, sur le pH ni sur la concentration moyenne d'ammoniaque, d'acide lactique, d'acide propionique, d'acide isobutyrique, d'acide valérique et d'acide isovalérique dans le rumen. Toutefois, on remarque une baisse (P < 0,05) de la concentration moyenne des acides gras volatils, de l'acide acétique et de l'acide butyrique quand on donne le concentré aux bouvillo...

“…Trabalhos têm mostrado que melhores resultados com amonização têm sido relatados em forragens com baixa qualidade, ou seja, menos de 6% de proteína bruta (PB) e 48% de nutrientes digestíveis totais (NDT), valores encontrados na maioria dos subprodutos agro-industriais e restos de culturas (Castrillo, et al, 1995;Fike, et al, 1995;Oliveira, et al, 1994). Goonewardene et al (1998), utilizando cevada (planta toda) amonizada ou não (1% base MS) na alimentação de novilhos com peso médio de 284 kg, não observaram diferenças no ganho de peso diário e na ingestão de matéria seca para os tratamentos.…”

“…Estes resultados podem ser atribuídos aos baixos níveis de amônia anidra adicionada às silagens (1,2%) e ao bom valor nutritivo. Fike et al (1995) utilizaram palhada de trigo amonizada (3% de NH 3 base MS) como volumoso para vacas de corte, e suplementação concentrada com os seguintes tratamentos: controle (sem suplementação), suplementação com 2,0 kg de concentrado contendo 12% de PB, suplementação com 2,0 kg de concentrado contendo 20,1% de PB e suplementação com 2,0 kg de concentrado contendo 31,7% de PB. Verificaram crescente ganho de peso e melhor condição corporal, à medida que se aumentou a proteína do concentrado.…”

RESUMO -Foram utilizadas 16 novilhas ½ Holandês/Indubrasil, com peso vivo médio de 230 kg, alojadas em baias individuais cobertas, distribuídas em um delineamento inteiramente casualisado, com quatro tratamentos e quatro repetições, definidos conforme a alimentação: T1 -Bagaço sem tratamento (controle); T2 -Bagaço tratado com 2,5% de Na 2 S; T3 -Bagaço tratado com 4% de NH 3 e T4 -Bagaço tratado com 2,5% de Na 2 S + 4% de NH 3 . Todos tratamentos foram feitos com base na matéria seca do bagaço. O bagaço de cana-de-açúcar ficou armazenado por 10 meses e, após a abertura dos silos, foi fornecido aos animais ad libitum, pela manhã (7 h), para obter sobras em torno de 10%, e todos animais receberam 3,5 kg/cabeça/dia de concentrado contendo 19% de proteína bruta. Verificou-se efeito para ganho de peso diário e total, observando-se ganhos maiores para os tratamentos com NH 3 . Os valores médios encontrados para ganho de peso diário foram 702, 684, 1026 e 1005 g/cab, respectivamente, para o bagaço sem tratamento, tratado com Na 2 S, tratado com NH 3 e tratado com NH 3 mais Na 2 S. O consumo de MS, em função do peso vivo, variou de 1,92 (controle) a 2,46% PV (NH 3 ), enquanto o consumo de FDN variou de 0,84 (controle) a 1,14% PV (NH 3 ).Palavras-chave: amonização, bagaço, resíduo Diets with of Sugarcane Bagasse Treated with Anhydrous Ammonia and/or Sodium Sulfate Fed HeifersABSTRACT -Sixteen ½ Holstein/Indubrasil heifers, averaging 230 kg of live weight, housed in individual boxes, were allotted to a completely randomized design, with four treatments and four replicates, according to the following treatments: T1 -bagasse without treatment (control); T2 -bagasse treated with 2.5% Na 2 S; T3 -bagasse treated with 4% NH 3 and T4 -bagasse treated with 2.5% Na 2 S + 4% NH 3 . All treatments were based on bagasse dry matter. Sugarcane bagasse was stored for 10 months e, after silo opening, animals were ad libitum fed, in the morning (7 a.m.), to obtain orts of approximately 10%, and all animals were fed 3.5 kg/head /day of concentrate with 19% crude protein. It was verified effect for daily and total weight gain, and the higher gains were observed for the treatments with NH 3 . The average values observed for daily weight gain were of 702, 684, 1026, and 1005 g/head, respectively, for the bagasse without treatment, treated with Na 2 S, treated with NH 3 and treated with NH 3 plus Na 2 S. DM intake, as a function of live weight, ranged form 1.92 (control) to 2.46% LW (NH 3 ) and NDF intake ranged from 0.84 (control) to 1.14% LW (NH 3 ).

-The objective of this study was to evaluate the effects of mineral and protein-energy (MPES), exogenous fibrolytic enzyme supplements (ES), combination of MPES + ES, and straw without supplement (WS) on digestibility, fermentation kinetic parameters, cumulative gas production, methane, CO 2 production, and volatile fatty acid concentration of rice straw of low and high nutritional value, estimated by in vitro techniques. The experimental design was randomized and factorial 2 × 4: two straws (low and high nutritional value) incubated with four supplements (MPES, ES, MPES + ES, and WS) and their interactions. Four experimental periods were used, totaling four replications per treatment over time. Data were analyzed by PROC MIXED of SAS. The in vitro dry matter and organic matter digestibilities of the rice straw with high nutritional value was improved by MPES, while the combination of MPES + ES supplements inhibited the digestibility of this straw. Dietary carbohydrate and nitrogen increased through MPES and MPES + ES supplements resulted in an increase in NH 3 -N concentration and a decrease in CO 2 production due to the microbial mass formation. However, this increase was not enough to improve organic matter degradability parameters, cummulative gas production, gas production kinetics, and acetate:propionate ratio and reduce methane emissions. The straw with high nutritional value showed greater content of nitrogen fraction a, effective degradability, cummulative gas production, and methane and CO 2 productions comparing with low-nutritional value straw. The use of MPES and MPES + ES supplements can be used as strategy to mitigate CO 2 in ruminant production systems that use rice straw.Key Words: digestibility, digestion kinetics, fatty acid, gas production, methane Revista Brasileira de Zootecnia
