Revista Brasileira de Zootecnia , 2003,
Abstract: Foram realizados três experimentos com 336 poedeiras no segundo ciclo de produ o e 24 meses de idade, alojadas em condi es de cria o comercial (550 cm2/ave). O objetivo foi avaliar o alho (5 kg/t), probiótico (300 g/t) e a virginiamicina (20 g/t) como aditivos de ra es antes, durante e após o estresse induzido pela muda for ada (MF). O delineamento experimental foi o inteiramente ao acaso e os tratamentos usados foram: dieta controle (DC); DC+alho (A); DC+probiótico (P); DC+virginiamicina (V); DC+A+V; DC+A +P; DC+P+V; DC+A+P+V, constituídos por sete repeti es de seis aves. O período pré-experimental foi de 15 dias e o fotoperíodo, de 17 horas de luz/dia. O ensaio 1 foi realizado em quatro semanas antes da MF, com as aves recebendo 110 g de ra o contendo os aditivos. O ensaio 2 foi realizado durante os doze dias de MF, com as aves recebendo 10 g de milho moído, usado como veículo para diluir a dose dos aditivos consumida em 110 g de ra o. O ensaio 3 foi realizado em seis semanas, durante o terceiro ciclo de produ o, com as aves recebendo 110 g de ra o, sem os aditivos, e as coletas tiveram início após as aves terem atingido 50% de postura. Antes da MF, o alho reduziu a massa de ovos em rela o ao probiótico (48,2 vs. 39,8 g) e, durante a MF, a virginiamicina e a mistura P+V reduziram a porcentagem de intestinos em rela o ao alho (7,51 e 7,72 vs. 9,43), mas o peso e a porcentagem de ba o n o foram alterados. Após a MF, as variáveis n o foram afetadas pelos tratamentos. Nas condi es do experimento, os antimicrobianos usados n o melhoram o desempenho de poedeiras antes, durante e após o estresse induzido pela MF em rela o à ra o sem aditivos.

Abstract: Um ensaio de metabolismo foi realizado para determinar os valores de EMV e EMVn da farinha integral de vagem de algaroba (FVA) com galos cecectomizados, utilizando o método Sibbald. Um experimento de desempenho foi realizado para avaliar os efeitos da inclus o da FVA em níveis de 0; 5; 10; 15; 20; 25; e 30% em ra es peletizada e farelada para poedeiras comerciais. No experimento 1, foram obtidos valores de EMV e EMVn de 2819 e 2806 kcal, respectivamente, enquanto a FVA apresentou cinco vezes mais celulose e quatro vezes mais lignina em compara o com o milho. No experimento 2, verificou-se que a peletiza o aumentou o peso vivo, peso dos ovos e da clara e a porcentagem de clara e reduziu a porcentagem de gema. O nível de 30% da FVA reduziu o peso e a massa de ovos e piorou a convers o alimentar, em compara o ao tratamento controle. Houve efeito quadrático do nível da FVA (como efeito principal) sobre o consumo de ra o, a produ o de ovos, massa de ovos, convers o alimentar por massa e porcentagens de casca, clara e gema. O consumo da FVA cresceu linearmente nas ra es peletizada e farelada em resposta ao seu aumento na ra o. A inclus o da FVA até 13,6%, em substitui o ao milho, em ra es isoprotéicas e isoenergéticas n o afetou adversamente o desempenho de poedeiras comerciais.

Abstract: Aiming to investigate the influence of T. gondii on semen parameters and spermatozoa morphology, eight boars were inoculated with T. gondii. Experimental groups consisted of: GI (n=3) 1,5 x 104 oocysts of P strain; GII (n=3) 1,0 x 106 tachyzoites of RH strain and GIII (n=2), control noninoculated. Evaluations of semen parameters (volume, motility, strength, concentration), study of spermatozoa morphology, serology (RIFI), parasitemia and hemograms were performed. For this purpose, blood and semen collection were carried out on days -2, -1, 1, 3, 5, 7, 9, 11, 14 and weekly until 84 days post-inoculation. Non hematimetrics alterations and clinical signs were observed on animals. Parasitemia was detected in an animal inoculated with oocysts, on the 7th day post inoculation (DPI) and in a two pigs of GII (tachyzoites), on the 3rd and 49th DPI. Serology results revealed the presence of antibody anti-T. gondii on the animals inoculated with oocysts or tachyzoites since 7th DPI, with tittles of 256 and 64, reaching a maximal level of 4096 on days 11 and 9 post inoculation, respectively. The GIII (control) was negative through out all experimental period. The semen parametersevaluated did not present any alteration due to toxoplasmosis. Significative differences (P<0,05), considering spermatozoa pathology, were not observed between inoculated and control groups. Com o objetivo de investigar a influência do Toxoplasma gondii nos parametros seminais e na morfologia espermática de suínos, oito reprodutores foram inoculados com T. gondii, sendo constituídos os seguintes grupos experimentais: GI (n=3) 1,5 x 104 oocistos da cepa P, via oral; GII (n=3) 1,0 x 106 taquizoítos da cepa RH, via subcutanea e GIII (n=2), controle. Foram realizadas avalia es de parametros espermáticos (volume, motilidade, vigor, concentra o), estudo da morfologia dos espermatozóides, exames sorológicos(RIFI), parasitemia e hemogramas. Para tanto, colheitas de sangue e sêmen foram realizadas nos dia -2, -1, 1, 3, 5, 7, 9, 11, 14 e semanalmente até 84 dias pós-inocula o. Nenhuma altera o hematimétrica e nos parametros clínicos foi observada nos animais. Parasitemia foi detectada em um animal inoculado com oocistos, no 7o dia pós-infec o (DPI) e em outros dois suínos do GII (taquizoítos), nos 3o e 49o DPI.Exames sorológicos revelaram a presen a de anticorpos contra T. gondii nos animais inoculados comoocistos ou taquizoítos a partir do 7o dia pós-infec o (DPI), com títulos de 256 e 64, alcan ando pico de4096 nos dias 11 e 9 pós-inocula o, respectivamente. O GIII (controle) manteve-se nega

Abstract: the main obstacle to the use of compost from urban waste in agriculture is the presence of heavy metals. once in the soil, their effect is accumulative and they may contaminate crops and water. the present study reports the evaluation of the chemical distributions of cu, pb, mn and zn in three different sized fractions (unsieved, < 1,18mm and > 1,18mm) of compost, by means of a sequencial extraction procedure and a chemometric analysis of the total content of all metals in each fraction. the pattern recognition methods showed significant differences in total heavy metal contents for the different fractions. the finest one was the most contaminated. meanwhile, this fraction presented lower amounts of metals in avaliable forms. this behavior can be attributed to the presence of metal particles in their elemental states in this fraction.
