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.

Revista Brasileira de Zootecnia , 2002,
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: O estudo foi realizado com o objetivo de avaliar o efeito da suplementa o com fitase em dietas com diferentes níveis de fósforo disponível sobre o desempenho de frangos de corte de 22 a 42 dias. Foram utilizados 1.080 frangos Cobb-500, distribuídos em delineamento experimental inteiramente casualizado, em esquema fatorial (3 x 4) com três níveis de fósforo disponível (0,30; 0,40 e 0,50%) e quatro níveis de fitase (0; 500; 1.000 e 1.500 UF), totalizando 12 tratamentos, cada um com seis repeti es de 15 aves. As variáveis avaliadas foram: consumo de ra o, peso vivo, ganho de peso, convers o alimentar e as características de carca a. O peso vivo e ganho de peso n o foram influenciados pelos níveis de fósforo disponível e pela adi o de fitase na dieta. Houve intera o entre os níveis de fósforo disponível e os níveis de fitase para consumo de ra o e para convers o alimentar. Verificou-se melhor convers o alimentar nas aves alimentadas com dietas contendo 0,30% de fósforo disponível com 1.500 UF kg-1. Os níveis de fósforo disponível influenciaram os rendimentos da coxa e do dorso, onde o melhor resultado foi com 0,30 e 0,40%, respectivamente. Recomenda-se a utiliza o de dietas contendo 0,30% de fósforo disponível, suplementadas com 1.500 UF kg-1. The study was carried out with the objective of evaluating the effect of phytase supplements in feeds with different levels of available phosphorus on the performance of broilers from 22 to 42 days of age. We used 1080 Cobb-500 chickens distributed in a completely randomized design, in a 3 x 4 factorial scheme, with three levels of available phosphorus (0.30; 0.40 and 0.50%) and four levels of phytase (0; 500; 1,000 and 1,500 UF), totaling 12 treatments, each with six replications of 15 birds. The variables evaluated were: feed intake, live body weight, weight gain, feed conversion and carcass characteristics. Live body weight and weight gain were not influenced by the levels of available phosphorus or adding phytase to the diet. There was interaction between the levels of available phosphorus and phytase levels for feed intake and feed conversion. Better feed conversion was seen in birds fed on diets containing 0.30% available phosphorus at 1,500 UF kg-1. The available phosphorus levels affected the development of the thigh and the back, where the best results were from 0.30% and 0.40% respectively. The use of a diet containing 0.30% phosphorus, supplemented with 1500 UF kg-1 is recommended.
