Abstract: O objetivo do trabalho foi avaliar o efeito de ra es fareladas, peletizadas e úmidas no desempenho de leit es na fase inicial. Realizou-se um experimento com 36 leit es mesti os (Landrace x Large White). A fim de se obter uma melhor precis o dos dados, dividiu-se o experimento em duas etapas, utilizando-se para cada etapa experimental dezoito animais na fase inicial (nove machos castrados e nove fêmeas), com peso vivo médio de idade inicial de 11kg, e 35 dias de idade, respectivamente. Em delineamento de blocos casualizados, esquema fatorial 3 x 2 (três formas físicas de ra o e dois sexos) e três repeti es, a análise conjunta dos dados demonstrou n o haver efeitos (P>0,05) para consumo diário de ra o, ganho de peso diário e final,convers o alimentar e custo com o fornecimento de ra o,assim como n o houve efeitos (P>0,05) na intera o ra o x sexo, concluindo-se que a forma física das ra es (farelada, peletizada e úmida) n o interferiu no desempenho dos leit es. PALAVRAS-CHAVE: Alimenta o, nutri o, tipo de processamento, suínos.

Abstract: an experiment was carried out to evaluate the effect of increase levels of jackfruit (artocarpus heterophyllus lam.) seeds bran in diet of japanese quails on egg production, yolk pigmentation and dropping humidity . a total of 180 japanese quails (coturnix coturnix japonica) with 42 days oold were distributed in a completely randomized design and fed diets with differents levels of 0; 2; 4; 6; 8 and 10% of jackfruit seeds bran (jsb). the variables feed intake, egg production, egg weigh, egg mass, feed egg mass conversion and feed egg dozen conversion as well as the yolk weight and yolk percentage, egg white, egg shell and egg yolk pigmentation. the data shown that increasing jsb in the diets reduced the egg production and higher feed egg dozen conversion lineally (p<0,05). therefore the egg yolk pigmentation improved up to 7.44% of jsb in the diet and the dropping humidity was higher up to 4.9% of jsb.the presence of antitrypsin factor is a possible explanation for lower performance on the japanese quails fed diets with increase of jsb fresh. in order to solve this problem e, it is recommended to expose the seeds to a thermal treatment, otherwise the jackfruit seed fresh should not be included in the diet for japanese quails.

Revista Brasileira de Zootecnia , 2003,
Abstract: O experimento objetivou estimar as exigências de lisina total e a rela o lisina: proteína em codornas, na fase de produ o. Foram utilizadas 320 codornas, resultado do cruzamento entre a codorna japonesa e a européia de 60 a 144 dias de idade, com peso vivo médio de 178+12 g, alimentadas com ra es contendo 20 e 23% de proteína bruta (PB) e, 0,80; 0,95; 1,10; 1,25 e 1,40% de lisina. O delineamento experimental foi o inteiramente ao acaso em esquema fatorial 2x5 (dois níveis de PB x cinco níveis de lisina), que resultou em dez tratamentos, cada um com quatro repeti es de oito aves. As codornas foram submetidas a um programa de luz de 17 horas de dura o e alimentadas à vontade. As variáveis estudadas foram obtidas em quatro períodos de 21 dias. Houve efeito quadrático dos níveis de lisina sobre a produ o de ovos, sendo a exigência e o consumo, respectivamente, de 1,07% e 287 mg de lisina/dia com 20%PB e de 1,15% e 321 mg de lisina/dia com 23%PB. O nível de 23%PB aumentou o consumo de ra o, produ o, peso e massa de ovos e também melhorou a convers o alimentar por massa e dúzia de ovos. As rela es lisina: PB n o foram alteradas, sendo de 5,3 e 5,0%, respectivamente, com 20 e 23% de PB na ra o. Os resultados do presente estudo sugerem aumento quantitativo da exigência de lisina de codornas na fase de produ o, mas n o da rela o lisina: PB, à medida que a concentra o de PB na ra o é elevada.

Abstract: the effect of antimicrobial (a) replacement with dehydrated egg (de) and of type of litter (new and recycled) used in the floor covering on pullet performance was evaluated in 1,440 1-d chicks, 720 of each strain (white and brown), allotted to 72 boxes (1 x 1.5 m). recycled litter consisted of sugar cane bagasse containing droppings of broilers chicks with symptoms of coccidiose. the pullets were weighed and assigned to a complete randomized design with a 3 x 2 x 2 (three diets x two litter x two strains) factorial arrangement, in a total of 12 treatments with six replications of 20 pullets. the experimental diets (d) were: d1 = diet with commercial dose of antimicrobial; d2 = diet without antimicrobial; and d3 = diet without antimicrobial + 0.6% of de. de was composed by dehydrated yolk+albumen (55°c for 72 hours) and showed negative result to samonella spp. test. the use of recycled litter decreased pullet performance of two genetic groups, specially the brown ones, that showed lower weights of spleen and bursa of fabricius. this fact suggests better enlargement of lymphoid tissues, and that probably explains the smaller tolerance of white pullets to recycled litter. the antimicrobials minimize negative effect of recycled litter on pullet performance. dehydrated egg is a good alternative to antimicrobials and can improve performance of pullets in the pre-starter on conventional environment.
