Abstract: Três experimentos foram realizados com o objetivo de avaliar o efeito da suplementa o enzimática em ra es à base de milho e soja sobre o desempenho (Experimento 1), a digestibilidade de nutrientes (Experimento 2) e o desempenho e o fluxo de nutrientes na digesta ileal (Experimento 3) em frangos de corte. No Experimento 1, para o cálculo das ra es experimentais, a composi o química do farelo de soja (FS) e da soja integral extrusada (SIE) foi superestimada em 7% para os valores de EM e PB e 5% para Met, Met+Cis e Lis (Trat. C, D e E) e 9% para EM, 7% para PB e 5% para Met, Met+Cis e Lis (Trat. F, G e H), quando houve a adi o de enzimas (Allzyme Vegproa e Allzyme Lipasea). Conclui-se que os valores de EM, PB e aminoácidos (Met, Met+Cis e Lis) da soja puderam ser superestimados em 9, 7 e 5%, respectivamente, quando houve a adi o de complexo multienzimático (Allzyme Vegproa) às ra es para frangos de corte (1-42 dias), sem prejuízo ao desempenho das aves. Os tratamentos utilizados nos experimentos 2 e 3 foram: A e B - ra es contendo farelo de soja (FS), sem e com adi o de complexo multienzimático (Allzyme Vegproa); e C e D - ra es contendo farelo de soja (FS) e soja integral extrusada (SIE), sem e com adi o de complexo multienzimático (Allzyme Vegproa). No experimento 2, n o foram observadas diferen as entre os tratamentos para os coeficientes de metaboliza o aparente de matéria seca, proteína bruta, energia bruta e a EMAn. No Experimento 3, para os períodos inicial (1-21 dias de idade), de crescimento (22-42 dias de idade) e total (1-42 dias de idade), n o foram observadas diferen as no consumo de ra o, no ganho de peso e na convers o alimentar das aves que receberam ra es suplementadas com enzimas. Na determina o do fluxo de nutrientes na digesta ileal, n o foram verificadas diferen as entre os tratamentos estudados, aos 21 e 42 dias de idade.

Abstract: The trial was performed to evaluate the effect of phosphorus sources on forage mass quality of Momba a grass (Panicum maximum Jacq. cv. Momba a), according to in vitro dry matter and organic matter digestibility and TDN concentration. Every month, samples of available forage mass were taken, from December, 2002 until April, 2003. The treatments were three phosphate sources (1-Yoorin ê magnesium thermophosphate; 2-Gafsa ê natural phosphate; 3-simple superphosphate + triple superphosphate) and the control (no fertilizer). They were arranged in a randomised block design with three replications. It was used 12 plots sized from 0,7 to 1,0 hectare, which were delimited by two-line eletric fence. The grazing method was continuous stocking and variable stocking rate (“put-and-take”). The IVDMD, IVOMD and TDN coefficients decreased along sampling period. IVDMD, IVOMD and TDN concentration didn’t show significantly differences among treatments (P>0.05). O trabalho foi realizado com o objetivo de avaliar o efeito de fontes de fósforo sobre a qualidade de massa de forragem do capim-Momba a (Panicum maximum Jacq. cv. Momba a), no que se refere à digestibilidade “in vitro” da matéria seca e da matéria organica e concentra o de NDT. Foram feitas amostragens mensais da massa de forragem disponível, no período de dezembro de 2002 a abril de 2003. Os tratamentos avaliados foram três fontes de fósforo (1-termofosfato magnesiano Yoorin ê; 2-fosfato natural Gafsa ê; 3-superfosfato simples + superfosfato triplo) e tratamento testemunha, distribuídos em delineamento de blocos casualisados com três repeti es. Foram utilizados 12 piquetes com tamanho de 0,7 a 1,0 hectare, separados por cerca com dois fios eletrificados. O método de pastejo utilizado foi o da lota o contínua com carga variável (“put-and-take”). Os coeficientes de DIVMS, DIVMO e NDT reduziram ao longo do período de coleta. Entre os tratamentos, a DIVMS, DIVMO e concentra o de NDT n o tiveram diferen a significativa (P>0,05).

Abstract: the objective of this work was to evaluate the chemical composition and aerobic stability of corn grain silage, added with crude soybean, sunflower or urea. the following treatments, arranged in a completely randomized design, with four replications, were evaluated: corn grain; corn grain plus soybean grain; corn grain plus sunflower grain; and corn grain plus urea. plastic barrels with 200 kg of capacity were used as experimental silos and kept closed for nine months. chemical composition, dry matter and crude protein ruminal degradability, starch ruminal disappearance, and the aerobic stability of silages were evaluated. the addition of soybean, sunflower or urea on silages influenced the effective degradability of dry matter and crude protein, and the chemical composition, especially in relation to crude protein and ether extract contents. the addition of 20% soybean, sunflower or urea (1%) in corn grain silage improves chemical composition, but decreases the effective degradability of dry matter and crude protein. urea addition to moist corn grain silage reduces losses on dry matter and improves the aerobic stability.

Abstract: the true protein digestibility in the small intestine of different ruminant feeds were measured using in situ and in vitro techniques. two steers with average body weight of 450 kg and fitted with ruminal cannulas were used for in situ incubation of different feeds. the following feedstuffs were evaluated: animal and vegetable protein concentrate, energy concentrate, fiber by-products, and forage. protein truly digested in the small intestine was estimated by pepsin or pepsin/pancreatin incubation with or without previous ruminal incubation. out of 30 evaluated feeds, ruminal incubation decreased the true protein digestibility in the small intestine of 24 feeds, increased that of feather meal, black oat, 2.5-mm particle size corn grain, and oat and tifton hays and had no effect on sunflower meal. these results showed that the small intestinal digestibility of rumen-undegradable protein from most analyzed feeds was lower than that of the original feed protein. with the exception of black oat, all remaining feeds (29) had greater true small intestinal protein digestibility after incubation with pepsin plus pancreatin showing the contribution of abomasal digestion on feed protein. because true small intestinal protein digestibility differed among feeds, is important to take it into account on diet formulation in order to accurately determine the requirements of metabolizable protein of ruminants.

Abstract: four corriedale wethers averaging 45 kg of body weight were randomly assigned to a 4 x 4 latin square to evaluate the effects of two carbohydrate sources (soybean hulls and corn grain) and two dietary forage levels (40 and 70%) on nutrient digestibility, n balance, and portal nutrient flux. animals were fitted with catheters in the mesenteric and portal veins and in the mesenteric artery. digestibility of nutrients and n balance were determined by total collection of feces and urine. portal plasma flow was measured by continuous infusion of p-aminohippurate, and net nutrient flux calculated as the difference between venous and arterial concentration times blood flow. dry matter digestibility and intake and digestion of ether extract were greater on corn than on soybean hulls diets while the opposite was observed for intake (789.7 g/d), digestion (444.2 g/d), and digestibility (56.2%) of ndf. there was a significant interaction between carbohydrate sources and dietary forage levels for intake and digestion of nfc; corn and lower forage diets resulted in greater intake and digestion of nfc whereas no effect of forage level was observed on soybean hulls diets. energy concentration expressed as tdn was higher for corn diets. diets with 40% forage showed improved n utilization because of the reduced excretion of n in urine and feces and increased n digestibility and retention. portal and arterial glucose concentrations were higher on animals fed corn and 40% forage diets. portal ammonia and urea concentration, venous-arterial difference and portal ammonia flux were all lower on diets with 40% forage.

Abstract: O objetivo do presente trabalho foi avaliar a concentra o de N-NH3, o pH do líquido ruminal e a eficiência de síntese microbiana de ra es que continham diferentes fontes energéticas: milho (MI), milho + casca de mandioca desidratada (MC), raspa de mandioca (RM) e farinha de varredura de mandioca (FV). Foram utilizados quatro novilhos da ra a Holandesa (270 kg), portadores de canulas ruminal e duodenal, distribuídos em um delineamento Quadrado Latino 4x4. A cinza insolúvel em ácido foi utilizada como indicador do fluxo duodenal e fecal. N o houve efeito das ra es experimentais no pH ruminal. No entanto, menor concentra o de N-NH3 foi observada para a ra o com FV. O fluxo duodenal de matéria organica e nitrogênio e a composi o química das bactérias ruminais n o foram influenciados pelas ra es experimentais. A maior eficiência microbiana aparente foi obtida para a ra o com FV. Nas condi es do presente experimento a FV, possivelmente apresentou uma melhor sincroniza o com a fonte protéica (farelo de soja), diminuindo a perda de nitrogênio na forma de N-NH3 e aumentando a eficiência microbiana.

Abstract: O objetivo deste trabalho foi avaliar a digestibilidade aparente dos nutrientes, o balan o de nitrogênio e a concentra o plasmática da uréia em dietas para ovinos com diferentes níveis de inclus o de farinha de penas hidrolisada. Foram utilizados cinco ovinos machos, castrados, com 50 kg de peso vivo. O delineamento utilizado foi o quadrado latino 5 x 5, em que os tratamentos consistiram em níveis de 0, 25, 50 , 75 e 100% de substitui o do farelo de soja mais uréia pela farinha de penas. O método utilizado para a determina o da digestibilidade e do balan o de nitrogênio foi a colheita total de fezes e urina. A ingest o da proteína bruta sofreu efeito quadrático, enquanto sua digest o sofreu efeito linear negativo, com a substitui o do farelo de soja mais uréia pela farinha de penas hidrolisada. Houve efeito linear positivo na excre o fecal e negativo na digestibilidade de matéria seca (MS), matéria organica (MO), proteína bruta (PB) e fibra em detergente neutro (FDN), com a inclus o da farinha de penas. Essa inclus o também influenciou de forma linear decrescente a ingest o de nutrientes digestíveis totais (NDT) e seu valor para as dietas. A inclus o da farinha de penas influenciou todas as variáveis estudadas no balan o de nitrogênio. Houve efeito linear crescente na excre o de nitrogênio nas fezes e na urina e decrescente na digestibilidade da matéria seca e na concentra o de uréia plasmática. Quanto ao nitrogênio consumido e retido houve efeito quadrático dos níveis de substitui o.
