Piglet performance in nursing phase when fed diets containing soybean protein concentrate/Desempenho de leitoes na fase de creche alimentados com racoes contendo proteina concentrada de soja
The experiment was developed in order to evaluate the effects of soy protein concentrate on performance and economic viability of piglets in nursery phase. We evaluated the following treatments in prestarter diets (25 to 37 days old), initial I (37 to 50 days age) and initial II diets (50 to 64 days...

Zusammenfassung: | The experiment was developed in order to evaluate the effects of soy protein concentrate on performance and economic viability of piglets in nursery phase. We evaluated the following treatments in prestarter diets (25 to 37 days old), initial I (37 to 50 days age) and initial II diets (50 to 64 days old): FS with corn and Hypro soybean meal, PCS-60% with corn and usual soy protein concentrate; PCSH-2h with corn and using PCS hydrolized by protease enzyme during 2 hours; PCSH-8h with corn and using PCS hydrolized by protease enzyme during 8 hours. In the period between 25-50 days were observed differences for the daily gross income (p = 5.1%) and gross margin (p = 2.1%). Treatments PCS-60% and PCSH(2h or 8h) showed the lowest values for daily gross income and gross margin, but in both cases, the PCS-60% treatment did not differ from FS. The inclusion of PCS-60%, and PCSH(2h or 8h) in diets for piglets in total nursery phase did not affect (p > 0.05) animal performance and economic viability. In view of performance the three PCS can be considered viable proteic ingredients in diets for piglets in the nursery phase. Keywords: proteic feedstuff, economic analysis, weight gain, nutrition, swine production. O experimento foi desenvolvido com os objetivos de avaliar os efeitos da proteina concentrada de soja nas dietas de leitoes no desempenho e viabilidade economica durante a fase de creche. Foram avaliados os seguintes tratamentos em dietas pre-inicial (25 a 37 dias de idade), inicial I (37 a 50 dias de idade) e inicial II (50 a 64 dias de idade): FS a base de milho e farelo de soja Hypro; PCS-60% proteina concentrada de soja; PCSH-2h com PCS hidrolisada com enzima protease por um periodo de 2 horas; PCSH-8h com PCS hidrolisada com enzima protease por um periodo de 8 horas. No periodo entre 25-50 dias foi observada diferenca significativa para a receita diaria (p = 5,1%) e para a margem bruta (p = 2,1%). Os tratamentos PCS-60%, PCSH-2h e PCSH-8h apresentaram os menores valores para receita diaria e margem bruta, porem, em ambos os casos, o tratamento PCS-60% nao diferiu do FS. A inclusao da PCS60%, PCSH-2h e PCSH-8h em dietas para leitoes na fase de creche nao influenciou (p > 0,05) o desempenho dos animais e a viabilidade economica. As tres PCS podem ser consideradas como opcao de ingredientes proteicos viaveis no ponto de vista de desempenho em dietas para leitoes na fase de creche.
