Valor nutritivo de silagens de sorgo
Souza Viviane Glaucia de,Pereira Odilon Gomes,Moraes Salete Alves de,Garcia Rasmo
Revista Brasileira de Zootecnia , 2003,
Abstract: Foram avaliados os consumos e as digestibilidades aparentes dos nutrientes de silagens de sorgo dos híbridos AG2006, AGX215, AGX213, AGX202 e AG2002. Utilizaram-se 20 carneiros adultos, sem ra a definida, castrados, com peso médio de 50,7 kg, distribuídos EM um delineamento em blocos casualizados, com quatro animais por tratamento. N o houve diferen a significativa entre as silagens para o consumo dos diversos nutrientes. Os consumos de matéria seca e nutrientes digestíveis totais expressos em g/dia revelaram valores variando de 936,2 (AGX202) a 1156,4 (AG2006) e de 460,9 (AGX215) a 613,4 (AGX213), respectivamente. Os coeficientes de digestibilidade diferiram entre as silagens, registrando-se maiores coeficientes de digestibilidade aparente da matéria seca e da matéria organica para a silagem do híbrido AGX213, em rela o às silagens dos híbridos AGX215, AG2006 e AG2002. Com base nos consumos e digestibilidades dos nutrientes, excetuando proteína bruta, os híbridos AGX 213e AGX202 mostraram-se promissores para a produ o de silagem.
Desempenho produtivo e parametros de carca a de cordeiros mantidos em pastos irrigados e suplementados com doses crescentes de concentrado = Productive performance and carcass traits of lambs grazing on irrigated pastures and receiving increasing concentrate levels
Rafael Araújo Souza,Tadeu Vinhas Voltolini,Luiz Gustavo Ribeiro Pereira,Salete Alves de Moraes
Acta Scientiarum : Animal Sciences , 2010,
Abstract: O presente estudo teve como objetivo avaliar o desempenho produtivo e os parametros de carca a de ovinos terminados em pastos irrigados de Tifton 85 que receberam doses crescentes de concentrado. Foram comparadas quatro doses de concentrado (0; 0,66; 1,33 e 2,00% da matéria seca - MS) em rela o ao peso corporal dos animais. O período experimental foi de 84 dias, divididos em quatro sub-períodos de 21 dias. Foram utilizados 24 animais testadores, machos, castrados, da ra a Santa Inês com peso corporal médio inicial de 20,5 ± 3,8 kg. O delineamento utilizado foi o inteiramente casualizado com seis repeti es. O aumento no teor de concentrado proporcionou maior peso corporal final, ganho médio diário, ganho de peso total, escore de gordura pélvico-renal, consumo de matéria seca total, comprimento externo da carca a, largura da garupa, largura do tórax, profundidade do tórax, perímetro da garupa e perímetro do pernil, além de menor consumo de forragem e contagem de ovos por grama de fezes. Entretanto, o rendimento de carca a quente n o foi influenciado pelas doses de suplemento concentrado. O aumento nas doses de concentrado para ovinos mantidos em pastagens de Tifton 85 melhorou o desempenho produtivo e o peso da carca a. The objective of this present study was to evaluate the productive performance and carcass traits of lambs finished on Tifton 85 irrigated pastures and receiving increasing levels of concentrate. Four levels of concentrate were compared on a dry matter basis (0, 0.66, 1.33 and 2.00%) in relation to the body weight of animals. The experimental period was 84 days, divided into four sub-periods of 21 days. Twentyfour Santa Ines male sheep, castrated, weighting 20.5 kg, were used as testers. The experimental design was completely randomized with six replications. The increase in concentrate levelspromoted higher final body weight, average daily gain, total weight gain, total dry matter intake, pelvic-renal fat score, external body length, rump width, chest width and depth, croup perimeter and ham perimeter, as well as lower forage dry matter intake and eggs per gram of feces. However, hot carcass dressing was not affected by concentrate supplementation. The increase in concentrate supplementation levels for lambs grazing on Tifton 85 irrigated pastures promoted higher productive performance and carcass weight.
Urea levels in multiple supplement for lambs grazing on buffelgrass = Teores de uréia no suplemento múltiplo de cordeiros mantidos em pastos de capim-búffel

Acta Scientiarum : Animal Sciences , 2010,
Abstract: The objective of present trial was to evaluate the intake of supplement dry matter, productive performance, carcass traits, and weight and yields of commercial meat cuts of lambs grazing on dormant buffelgrass pastures and receiving multiple supplementation containing different urea levels. Urea levels used were: 5, 8, 11 and 14% on dry matter. Thirty-six male lambs were used, nine animals per treatment, with 18.0 ± 2.0 kg initial body weight, distributed into four groups. The experimental design was completely randomized with nine replications. Urea levels in supplement did not influence productive performance, cold and hot carcass weight and yield and commercial meat cuts weight and yield (leg, shoulder, rib and brisket). Use of multiple supplements containing 11 and 14% of urea levels for lambs in dormant grazing pastures during the dry season may increase bioeconomic performance of this activity, as they promoted lower supplement intake and similar productive performance. O objetivo do presente estudo foi avaliar o consumo de matéria seca de suplemento, o desempenho produtivo, os parametros de carca a e os rendimentos de cortes cárneos comerciais de cordeiros mantidos em pastos diferidos de capim-búffel recebendo suplementos múltiplos com diferentes teores de uréia. Foram utilizados quatro teores de uréia, sendo 5, 8, 11 e 14% na matéria seca. Foram utilizados 36 cordeiros machos, nove animais por tratamento, com peso corporal inicial médio de 18,0 ± 2,0 kg, distribuídos em quatro grupos. O delineamento experimental adotado foi o inteiramente casualizado com nove repeti es. Os teores de uréia no concentrado n o influenciaram os ganhos médios diários, os ganhos de peso totais, os pesos corporais finais, os pesos e os rendimentos de carca a quente e fria e os pesos e rendimentos de cortes cárneos comerciais (pernil, paleta, costela e carré). O fornecimento de suplementos múltiplos contendo 11 e 14% deuréia para ovinos criados em pastagens diferidas na esta o seca resultaram em melhores desempenhos bioecon micos para a atividade, já que, com menores consumos de suplemento os animais atingiram desempenhos semelhantes.

Abstract: the use of concentrate for sheep grazing buffel grass may improve the productive performance and carcass traits of animals. the objective of present trial was to evaluate the productive performance and carcass traits of sheep grazing buffel grass receiving different concentrate levels. the concentrate levels used were: 0; 0.33; 0.66 and 1.0% of dry matter in relation to body weight. forty lambs were used, ten animals by treatments, with 16.5 ± 2.0 kg of initial body weight and 20.97 kg final body weight, distributed in four groups. the experimental design was a completely randomized with ten replicates by treatments. the concentrate levels did not influence the cold and hot carcass weight. however, the increasing levels of concentrate promoted higher cold and hot carcass yield. blood, head, hide, heart, lung, kidney and liver (non carcass components) weights and proportion of slaughtered body weight (sbw) and leg, shoulder, brisket, rib, neck and loin weights (commercial meat cuts) were not affected by increasing levels of concentrate. full intestine in proportion of sbw was lower with the increase of concentrate levels, while the brisket's weight was higher with increase of concentrate.
Propostas alternativas de constru??o de políticas públicas em educa??o: novas esperan?as de solu??o para velhos problemas?

Abstract: this paper examines the possibility of constructing alternative public education policies, not only theoretical proposals, but also educational policies that have been constructed in opposition to the brazilian tradition of vertical relations between the state and civil society. even taking into account the difficulties that characterise paradigm shift in education policies, it can be seen that new approaches to such policies have been constructed in a number of brazilian cities in recent years. these experiences reflect forms of government that involve the concept of democratisation of the relations between state and society, which may represent new hope for solving old problems.

é possível a constru o de políticas públicas emancipatórias em educa o?
Salete Moraes Campos de
Revista Portuguesa de Educa??o , 2004,
Abstract: This paper proposes the construction of new spaces for democratic debate, called new agoras, which would form systems or networks for constructing educational policies. The systems would be non-hierarchical, where each part feeds and is fed by the others, and each new agora would be guided by ethical knowledge, emancipatory knowledge and multiculturalism. The paper also proposes a reconfiguration of the state also guided by ethics and multiculturalism which we call the coordinator-articulator state. We argue that this autopoietic system, in synergy with the coordinator-articulator state, would lead to the formulation of emancipatory education policies. Rather than seeking "the" alternative, the aim is to develop a theoretical proposal that will permit the elaboration of public policies that have emancipatory projects as their aim.

Abstract: intake, digestibility of nutrients, daily weight gain, and feed conversion were evaluated in beef cattle receiving diets containing the following ratios of sorghum silage:tifton 85 haylage: 0:100; 32:68; 66:34; and 100:0. diets were formulated to be isonitrogenous (12% crude protein) with a forage:concentrate ratio of 60:40, on dm basis. twenty-four crossbred holstein x zebu steers averaging 360 kg of initial body weight were distributed in a completely randomized block design with 15 days for diet adaptation followed by three experimental periods of 28 days each. indigestible acid detergent fiber (iadf) was used to estimate fecal output. mean daily intakes of dm, om, cp, ee, tc, and tdn all were not affected by treatments with mean values of: 9.46, 9.05, 1.20, 0.52, 7.4, and 6.23 kg/day, respectively. significant quadratic effects were observed for the apparent total tract digestibilities of dm, om, cp, and ee with estimated minimum digestibilities of 60.33, 61.58, 61.89, and 55.83% for the levels of 44.80, 47.18, 50.95, and 51.21% of sorghum silage in the forage portion of the diet, respectively. mean daily weight gain and feed conversion also were affected quadratically by increasing the level of sorghum silage in the forage portion of the diet with estimated maximum and minimum values of 1.25 kg/day and 7.66 for the levels of 60.95 and 67.04% of sorghum silage, respectively. results indicated that varying dietary ratios of tifton 85 haylage and sorghum silage is a good alternative for feeding forage to finishing beef cattle. inclusion of approximately 60% of sorghum silage in the total dietary forage resulted in the greatest estimated weight gain.
